*** SECURITY REMINDER ***
You are browsing as root on an outdated kernel that is not likely to see timely security patches. You should at least create a non-root user (e.g. using adduser), but they would need permission to use the framebuffer i.e. FBInk, if they want to use the graphical image viewer feature. To create a user 'fbuser' with framebuffer access you can do the following: adduser fbuser addgroup fbgroup adduser fbuser fbgroup chgrp fbgroup /dev/fb0 But it looks like you have to redo that last chgrp command each session. Furthermore, Kobo seems to have disallowed write access to /mnt/onboard to anyone but root, so other users cannot save bookmarks to .elinks/ but they can at least save downloads to the /tmp directory (of course you then have to copy them as root to a more permanent location). *NOTE* You can edit the "umask 002" line in /etc/init.d/rcS to "umask 000" allow all user write access to the /mnt/onboard partition, but that would defeat the security objective. You can't have fine-grained access permission because it is a vfat format. When you create a user with "adduser bla", a /home/bla directory is created on the root partition, which DOES have fine-grained access controls, as you can see by running "ls -l /home". But the root partition doesn't have much free space, only about 60MB, as you can see by running "df". So you may prefer "adduser bla -d /mnt/onboard/.adds/koreader/home/bla" to put the home directory on the /mnt/onboard partition which has many GB of free space, which the user won't be able to write to, but at least it doesn't use up valuable root partition space. In retrospect I should have crosscompiled using "--prefix=/mnt/onboard/.adds/koreader/templib" on my desktop instead of "--prefix=$HOME/Downloads/mykobossh/templib", so I wouldn't have to use up valuable root partition space with all the certificates, as you will see. The links near the bottom of this post point to an alternative approach using a chroot. Clara HD owners also have the option to pull out the SD card and shrink the /mnt/onboard partition with a disk utility, then creating a new /home partition that is writable by non-root users. But non-Clara owners can still create a /home partition in an image file, as was done here, (but no need to create root file system - just format it and mount it.) **EDIT - Comment #3 has another way to get elinks by copying and may be easier. Otherwise: 1.Back up your SD card. 2.Don't use your Kobo for sensitive info including passwords. 3.Don't browse to unsafe sites. Or just use Firefox on your desktop to save complete webpage with image folder, or print to pdf on your cellphone, these can be webserved to your Kobo for secure graphic browsing using KOReader! As mentioned here *** HOW TO CROSSCOMPILE ELINKS AND WGET FOR THE KOBO CLARA HD (using linux desktop). --- First, follow the instructions here to determine the crosscompile tool for your device. For the Kobo Clara HD, it is gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz. Download this and source packages for openssl, elinks, and wget to $HOME/Downloads/mykobossh/. --- To build OPENSSL: (see also) cd cd Downloads/mykobossh/ tar xJf gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz export PATH=$PWD/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf/bin:$PATH tar zxvf openssl-1.1.1s.tar.gz cd openssl-1.1.1s/ mkdir $HOME/Downloads/mykobossh/templib ./Configure gcc -static -no-shared --prefix=$HOME/Downloads/mykobossh/templib --cross-compile-prefix=arm-linux-gnueabihf- make make install cd .. --- To build ELINKS: (see also) tar zxvf elinks-0.15.1.tar.gz cd elinks-0.15.1/ ./autogen.sh ./configure --help ./configure --host=arm-linux-gnueabihf --enable-own-libc --enable-sm-scripting --disable-nls --disable-xbel --disable-ipv6 --disable-leds --disable-backtrace --with-static --without-zlib --without-bzlib --without-gnutls --with-openssl=$HOME/Downloads/mykobossh/templib CPPFLAGS="-I$HOME/Downloads/mykobossh/templib/include" LDFLAGS="-L$HOME/Downloads/mykobossh/templib/lib" make cp src/elinks ../elinks111s cd .. --- DEVICE: Copy elinks111s to .adds/koreader/scripts directory on Kobo Clara HD. Run KOReader and connect to WIFI on Clara HD. Open Terminal Emulator and you will see elinks111s in working directory (/mnt/onboard/.adds/koreader/scripts). chmod +x elinks111s elinks111s (enter "mobileread.mobi/forums/") (keep pressing return key if get ssl error message) ***EDIT*** It helps to copy certificates to a $HOME/Downloads/mykobossh/templib/ssl/certs directory that you must create on your Kobo, where $HOME is /home/user, or whatever your desktop home directory was. I got certificates from my desktop /usr/share/ca-certificates/mozilla directory, but your case may differ. Also, a heavy page like amazon might stall, but I press q then cancel and it seems to get going again! *Update-wget seems to handle certs differently. A workaround might be to copy the ca-certificates.crt file from your desktop (mine was in /etc/ssl/certs) to the above directory, and let wget know by creating a .wgetrc file in /mnt/onboard/.adds/koreader with the single line: ca_certificate=/home/user/Downloads/mykobossh/templib/ssl/certs/ca-certificates.crt (or wherever you saved it). ** Update-Courtesy of qkqw's post, here is another source of Mozilla CA certificates from the Curl website. *** Press Esc key and down arrow key to get menu and key codes. Use spacebar for pagedown and 'b' for pageup, 'g' followed by '.' to browse local filesystem. Press q (followed by return key) to quit --- NiLuJe's FBInk can be configured as an image viewer for elinks, except the image gets quickly overwritten. But it is there long enough to decide if you want to download it. Turns out I had to not use the FBInk that came with my installed KOReader but to download it separately from here. EDIT elinks.conf FILE IN .elinks/ (TO CONFIGURE fbink AS IMAGE VIEWER): set document.browse.images.display_style = 1 set document.browse.images.filename_maxlen = 50 set document.browse.images.image_link_tagging = 2 set document.browse.images.show_as_links = 1 set mime.extension.jpg="image/jpeg" set mime.extension.jpeg="image/jpeg" set mime.extension.png="image/png" set mime.extension.gif="image/gif" set mime.extension.bmp="image/bmp" set mime.extension.pnm="image/pnm" set mime.handler.image_viewer.unix.ask = 1 set mime.handler.image_viewer.unix-xwin.ask = 0 set mime.handler.image_viewer.unix.block = 1 set mime.handler.image_viewer.unix-xwin.block = 0 set mime.handler.image_viewer.unix.program = "/mnt/onboard/.adds/koreader/scripts/fbink -g file=%" set mime.handler.image_viewer.unix-xwin.program = "/mnt/onboard/.adds/koreader/scripts/fbink -g file=%" set mime.type.image.jpg = "image_viewer" set mime.type.image.jpeg = "image_viewer" set mime.type.image.png = "image_viewer" set mime.type.image.gif = "image_viewer" set mime.type.image.bmp = "image_viewer" set mime.type.image.pnm = "image_viewer" --- *EDIT* Actually "fbink -G -g file=% ;sleep 2" keeps the image longer. I tried appending 2>/dev/null but that only helps outside of elinks. *You need that space between "%" and ";" for some reason. Another option is: "fbink -G -y 30 -g file=% ;sleep 2" Which keeps the image to the lower part of the display, so it doesn't get overwritten. --- To build WGET: (see also) tar zxvf wget-1.21.tar.gz cd wget-1.21/ ./configure --help env CPPFLAGS="-I$HOME/Downloads/mykobossh/templib/include" LDFLAGS="-L$HOME/Downloads/mykobossh/templib/lib" ./configure --with-ssl=openssl --with-libssl-prefix=$HOME/Downloads/mykobossh/templib --target=arm-linux-gnueabihf --host=arm-linux-gnueabihf --disable-nls --disable-ipv6 --without-zlib make CPPFLAGS="-I$HOME/Downloads/mykobossh/templib/include" LDFLAGS="-L/$HOME/Downloads/mykobossh/templib/lib -static" cp src/wget ../wget111s DEVICE: Copy wget111s to .adds/koreader/scripts directory on Kobo Clara HD. Run KOReader and connect to WIFI on Clara HD. Open Terminal Emulator and you will see wget111s in working directory (/mnt/onboard/.adds/koreader/scripts). chmod +x wget111s wget111s google.com ls index.html Here is a more sophisticated use: ***NOTE THE VERY IMPORTANT OPTION '-Q50M' WHICH LIMITS DOWNLOAD TO 50MB !!!*** (this is to keep you from inadvertently "downloading the internet") wget111s --no-check-certificate --no-parent -k -nd -D www.mobileread.mobi -E -r -A jpg,jpeg,png,gif,htm.html -l1 -Q50M -P ./mywgets/ www.mobileread.mobi/forums/ ------ THE NEXT SECTIONS ARE OPTIONAL, IF YOU WANT AN ASCIIVIEW IMAGE VIEWER. *It is for ascii images - not high resolution images, from when I could not get NiLuJe's FBInk to work within elinks. So this is mostly just a fun substitute! Spoiler:
Finally, if you have gotten this far and said, whew, that was a lot, then "HOWTO Create your own native development environment on your Kobo!" might be making a lot more sense now! *EDIT:Looks like graphical browser with Xorg is also available via chroot. Extra Clara HD config steps on post #46.. So there you have an almost graphical browser. *Actually, if you use wget (the real one you compiled above, or maybe the cURL binary installed from NiLuJe's kobostuff package - not the stripped-down one that comes with KOReader) you can with a little practice download a page WITH images and that can be opened WITH IMAGES(if they are local, like saved as complete webpage by Firefox) in KOReader for a graphical view!

***TO DOWNLOAD "COMPLETE" WEB PAGE (Firefox-style)***
Follow instructions at this link to add uri passing to our cross-compiled wget111s command from above, except name the entry "wgets", use the command "wget111s --no-check-certificate --show-progress -nd -E -k -p -Q20M %c", and assign keybinding "Ctrl-W". Press ENTER key and save by tabbing to the "SAVE" button and pressing ENTER, then ESC to get back to current page. Now, if you press g, then "g" for google, followed by ENTER, elinks will take you to the google search page. Enter "Ctl-w" and complete web page is saved to current directory. To verify, press g, then "." for current local directory, followed by ENTER, then maybe "Ctrl-r" to refresh cache, and a few down-arrow presses to scroll, and voila, your complete web page with images! Now if you want to browse this page in the luxury of the KOReader environment, turn off networking to be sure you are looking at locally saved files, and browse to your download directory in KOReader to see the "complete" web page with images displayed. *Note-this option was done while running elinks111s as root, so that the change would be written to the elinks.conf file. *LONG INSTRUCTIONS FROM LINK: Spoiler:

***PLS SEE SECURITY REMINDER ON TOP POST***
COPYING ELINKS BINARY TO KOBO CLARA HD WITHOUT COMPILING OR CHROOT: (Some may find this an easier way to get the elinks browser.) You can see dependencies of elinks from here. Depends (6) libbz2 libcrypto3 libexpat libssl3 musl zlib You can get the packages from here. You can get a CA certificate store from here. DOWNLOAD THE REQUIRED PACKAGES: $ wget https://dl-cdn.alpinelinux.org/alpin...-0.15.1-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...2-1.0.8-r4.apk $ wget https://dl-cdn.alpinelinux.org/alpin...3-3.0.8-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...t-2.5.0-r0.apk $ wget https://dl-cdn.alpinelinux.org/alpin...3-3.0.8-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...l-1.2.3-r4.apk $ wget https://dl-cdn.alpinelinux.org/alpin...-1.2.13-r0.apk $ wget https://curl.se/ca/cacert.pem RUN THESE COMMANDS FROM LINUX DESKTOP OR ENVIRONMENT(really just need to unarchive and copy some files, but the tar command fails if you try it on the vfat filesystem /mnt/onboard of the Kobo because of vfat not supporting symlinks.

Copy your elinks binary from the scripts/ folder on the PC to the /mnt/onboard/.adds/koreader/scripts/ folder on the kobo. Note the contents of /mnt/onboard/.adds/koreader/libs/ already has a libz.so.1 lib. Copy all libs except libz.so.1 from the libs/ folder on the PC to the /mnt/onboard/.adds/koreader/libs/ folder on the kobo. Note that these new libs all have a different date than the default pre-existing libs. Copy your cert.pm and certs/ca-certificates.crt to the /etc/ssl/ directory.(You may notice there is already one in the /mnt/onboard/.adds/koreader/data/ folder anyway.) RUN THESE COMMANDS IN KOREADER TERMINAL, OR FROM A TELNET/SSH CLIENT CONNECTION: ***SECURITY REMINDER*** Telnet sessions are in cleartext INCLUDING LOGIN SESSIONS, so only use on a private network, if at all! If you always have DEVMODE set to ON for whatever reasons , that means Telnet is on by default, unless you toggle it off , e.g. using NickelMenu. You can install KOReader to get the more secure SSH option, and NiLuJe's kobostuff provides a package that includes an SSH binary. You can start the KOReader SSH server via NickelMenu. ********************************** IF RUNNING FROM KOREADER TERMINAL: # elinks IF RUNNING FROM A TELNET/SSH CLIENT CONNECTION: # cd /mnt/onboard/.adds/koreader/ # export LD_LIBRARY_PATH=/mnt/onboard/.adds/koreader/libs/ # echo $LD_LIBRARY_PATH # ./scripts/elinks You then enter '.' to see current working directory, or enter a web address (just keep pressing return if you get SSL errors).

But if you download packages from the edge branch, as was the case for moon-buggy, its dependencies will keep changing as the rolling edge branch keeps updating. So at some point the provided links will be out of date, and you would have to search for the package yourself in the edge branch or the latest branch(e.g. 3.18): https://pkgs.alpinelinux.org/packages?arch=armv7 This would list the up-to-date dependencies.

There was a framebuffer-based terminal emulator that runs on the Clara HD (you have to compile it), which you can control from your phone or PC keyboard: https://www.mobileread.com/forums/sh...d.php?t=298877 These are the build directions if you have a couple of hours to kill (binary attached for your convenience.) *** On a debian PC: koreader/koxtoolchain https://github.com/koreader/koxtoolchain $ git clone https://github.com/koreader/koxtoolchain.git $ cd koxtoolchain/ $ sudo apt-get install build-essential autoconf automake bison flex gawk libtool libtool-bin libncurses-dev curl file git gperf help2man texinfo unzip wget $ ./gen-tc.sh kobo (2 hours build time on an Acer Chromebook 11 converted to an MX Linux workstation) $ cd .. *** $ mkdir fbpad-build $ cd fbpad-build/ JulianDroske/fbpads https://github.com/JulianDroske/fbpads forked from aligrudi/fbpad $ wget https://github.com/JulianDroske/fbpa...ads/master.zip $ unzip fbpads-master.zip $ cd fbpads-master/ $ make $ cd fbpad_mkfn/ $ make $ nano -l gen.sh 5 OP="-h34 -w19" 6 SZ="18h135v135" 7 # OP="-h26 -w14" 8 # SZ="18h100v100" $ ./gen.sh $ cd .. $ cd .. *** NiLuJe/FBInk https://github.com/NiLuJe/FBInk/releases $ wget https://github.com/NiLuJe/FBInk/rele...v1.25.0.tar.xz $ tar xJf FBInk-v1.25.0.tar.xz $ cd FBInk-v1.25.0/ $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ make static stripped $ cd .. ddvk / fbpad-eink forked from kisonecat/fbpad-eink https://github.com/ddvk/fbpad-eink $ wget https://github.com/ddvk/fbpad-eink/a...ads/master.zip $ unzip fbpad-eink-master.zip $ cd fbpad-eink-master/ $ cp -r ../FBInk-v1.25.0/Release FBInk/ $ cp ../FBInk-v1.25.0/fbink.h FBInk/ $ cp ../fbpads-master/fbpad_mkfn/ar.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ai.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ab.tf fonts/ $ nano -l conf.h 17 typedef int fbval_t; ... 20 #define FR "ab.tf" 21 #define FI "ab.tf" 22 #define FB "ab.tf" $ nano -l Makefile 3 CC := arm-kobo-linux-gnueabihf-gcc ... 10 xxd -i fonts/ab.tf > font.h $ nano -l font.c 40 memcpy(&head, fonts_ab_tf, sizeof(head)); ... 46 font->glyphs = (int*)(fonts_ab_tf + sizeof(head)); 47 font->data =(char*) (fonts_ab_tf + sizeof(head) + font->n * sizeof(int)); $ xxd -i fonts/ab.tf > font.h $ make $ file fbpad fbpad: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.33, with debug_info, not stripped $ cd .. *** Copy the fbpad binary to the /mnt/onboard/.adds/koreader/scripts/ directory on your Kobo.

(Try elinks if you have good eyesight.)UPDATE- Fixed font size - now very readable. Hit the lower right corner of the screen and the nickel menu comes up. Ctl-Alt-q to quit If that doesn't work, try "pkill fbpad". *** How about let's change the default elinks keybindings to allow normal use of arrow keys: The hard way (see below for the easier way): In elinks, press 'k' to bring up Keybinding manager. Press Space to expand [+]- Main mapping. Use Right arrow to move focus to Delete tab. Use Down arrow to scroll to and delete the following: [-]- Move to the next frame: Tab [-]- Move to the previous frame: Shift-Tab [-]- Return to the previous document in history: Left [-]- Go forward in history: u [-]- Follow the current link: Right [-]- Follow the current link, forcing reload...: Ctrl-Right [-]- Open a lua Console: , [-]- Move to the next link: Down [-]- Move to the previous link: Up [-]- Move downwards by a page: Ctrl-F [-]- Move upwards by a page: Ctrl-B [-]- Search link text by typing ahead: # [-]- Toggle displaying of links numbers: . Use Right arrow to move focus to Save tab. Save and Close. Press 'k' to bring up Keybinding manager again. Press Space to expand [+]- Main mapping, or Up arrow to scroll to the top if already expanded. Use Left/Right arrow to focus on Add tab. Use Down arrow to scroll to and add the following: [-]- Move to the next frame: Ctrl-f [-]- Move to the previous frame: Ctrl-b [-]- Return to the previous document in history: , [-]- Go forward in history: . [-]- Show information about current link: u [-]- Open a lua Console: Alt-l [-]- Move cursor down: Down [-]- Move cursor left: Left [-]- Move cursor right: Right [-]- Move cursor up: Up [-]- Move to the next link: Tab [-]- Move to the previous link: Shift-Tab [-]- Toggle displaying of links numbers: # Use Right arrow to move focus to Save tab. Save and Close. The easier way: Or you could just append to the end of the config file: $ vi .elinks/elinks.conf Code:
################################## # Automatically saved keybindings # bind "main" "Ctrl-F" = "frame-next" bind "main" "Ctrl-B" = "frame-prev" bind "main" "," = "history-move-back" bind "main" "." = "history-move-forward" bind "main" "u" = "link-info" bind "main" "Alt-l" = "lua-console" bind "main" "Down" = "move-cursor-down" bind "main" "Left" = "move-cursor-left" bind "main" "Right" = "move-cursor-right" bind "main" "Up" = "move-cursor-up" bind "main" "Tab" = "move-link-next" bind "main" "Shift-Tab" = "move-link-prev" bind "main" "#" = "toggle-numbered-links" bind "main" "Ctrl-Right" = "none" So the new way of navigating in elinks would be: On startup, enter '.' to see current working directory, or enter a web address. Tab and Shift-Tab to traverse the links. Enter to follow link or '.' and ',' to go forward and back. Space and 'b' to page forward and back. '[' and ']' to go left and right. Enter to edit a text field, 'd' to download link. 'a' to add a bookmark, 's' to see them, TAB to move through options. ESC followed by Down arrow and Left/Right arrows to see menus. 'g' to enter a new address, 'q' to quit. Main difference being now able to move around the page with arrows keys. Old Down/Up link travelling replaced by Tab/Shift-Tab, and old Left/Right history traversing replaced by ','/'.'. *** Also get rid of the colors in the ls command by appending this to the /korenv.sh file: # vi /korenv.sh Code:
#!/bin/sh export PATH=$PATH:/mnt/onboard/.adds/koreader/scripts:/mnt/onboard/.adds/koreader/plugins/terminal.k export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/onboard/.adds/koreader/libs export TERM=xterm export HOME=/mnt/onboard/.adds/koreader/ cd $HOME alias ls='ls --color=never' But it seems you have to run it again after running fbpad. *** To get rid of the colors in the w3m browser: In w3m, normally press 'o' to bring up the Option Setting Panel. Scroll down to the second group, Color Settings. Put the cursor on the first entry: Display with color. Tab to the ()NO option and press enter. Scroll to the end of the section, tab to the [OK], and press enter. Or just edit the config file: $ nano -l .w3m/config 38 color 0 But w3m doesn't handle very well fbpad with large font/low number of columns. Or at all, as you can see with the small-font "fbpads" that I reuploaded. Note: the "fbpads" I uploaded means "fbpad with Small font", not because it is the above JulianDroske/fbpads that I exploited earlier in the post for its font setup. Sorry for any confusion. *** Networking note: In Quitting Telnet Habit , I said that I wanted to quit telnet and turn off devmode ( Go to the Discover tab and search the store for "devmodeoff"). meaning I lost the "ForceWifiOn=true" option in [DeveloperSettings] in the /mnt/onboard/.kobo/Kobo/Kobo eReader.conf file. Unfortunately I now find the WiFi connection cutting out. Others have said leaving the Wifi applet dialog open helps, so I am trying that. *** * UPDATE: You do NOT need DEVMODEON to set the "ForceWifiOn=true" option in [DeveloperSettings] in the /mnt/onboard/.kobo/Kobo/Kobo eReader.conf file. I tested it that WiFi shuts off automatically after 1-2 minutes of inactivity, but will stay on if "ForceWifiOn=true" in [DeveloperSettings] in the /mnt/onboard/.kobo/Kobo/Kobo eReader.conf file, EVEN IF DEVMODEOFF. Also, interestingly, "EnableDebugServices=false" stopped telnet and logread from running automatically even if DEVMODEOFF. Unfortunately, that option stopped my oskansi fbpad terminal from working. I will need to investigate that.., *** Here's one with keyboard: NiLuJe/inkvt forked from llandsmeer/inkvt https://github.com/NiLuJe/inkvt $ mkdir inkpad-build $ cd inkpad-build/ $ wget http://http.us.debian.org/debian/poo....1.1-1_all.deb $ sudo dpkg -i libcxxopts-dev_3.1.1-1_all.deb OR $ sudo apt install libcxxopts-dev $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ cp ../fbpad-build/FBInk-v1.25.0.tar.xz . $ tar xJf FBInk-v1.25.0.tar.xz $ wget https://github.com/NiLuJe/inkvt/arch...ads/master.zip $ unzip master.zip $ mv master.zip inkvt-master.zip $ cd inkvt-master/ $ mv ../FBInk-v1.25.0/* FBInk/ $ mkdir cxxopts/include $ cp /usr/include/cxxopts.hpp cxxopts/include/ $ make release Extract InkVT-.zip to Kobo.

Note developer's warning on inkVT github page: Warning: this project is very experimental! It might brick your device. Only install this if you know what you are doing. Happy with just fbpad for now.

Fbpad & USB
It seems there is somewhat flaky support for USB keyboard for fbpad on the Kobo, if you have some productive time to fritter away...
* requires USB host support: https://www.mobileread.com/forums/sh...d.php?t=340418 DOWNLOAD THE AGETTY PACKAGE: $ cd myalpine/ $ wget https://dl-cdn.alpinelinux.org/alpin...-2.38.1-r1.apk RUN THESE COMMANDS FROM LINUX DESKTOP: $ tar zxvf agetty-2.38.1-r1.apk $ mv sbin/agetty scripts/ NOW CONNECT YOUR KOBO TO YOUR PC: Copy your agetty binary from the scripts/ folder on the PC to the sbin/ folder on the kobo. ***UPDATE*** CRITICAL STEP (or agetty won't run): # cp /mnt/onboard/.adds/koreader/libs/ld-musl-armhf.so.1 /lib/ *** Edit system file on your Kobo at your own risk (may blow up your device - just kidding, but type carefully) : EDIT /sbin/kobo_getty.sh Code:
#!/bin/sh [ -e /dev/ttymxc0 ] && /sbin/getty -L ttymxc0 115200 vt100 & [ -e /dev/ttyS0 ] && /sbin/getty -L ttyS0 0 vt100 & [ -e /dev/tty1 ] && /sbin/agetty -s 38400 -t 600 tty1 vt100 If I may paraphrase NiLuJe, "Here Be Dragons", where "Dragons" be a metaphor for messing up core system functionality possibly leading to failure to startup or connect, or even mysterious application malfunctions that manifest later on. These system files were put there by folks with comprehensive system level understanding, to be modified by folks who have invested many person-hours code-grokking/reverse engineering to achieve comparable understanding. Since I am neither, what is my excuse? Well on my Clara HD the first two lines are exactly the same except I added the "&" at the end. I then added the third line which I have researched the meaning of. Also I have multiple backups and contingency plans for connecting to and/or re-establishing my Clara. Also, it only cost 99 US$, is not used for work, and contains no important data. So non-expert readers, please make your own risk assessment. Edit NickelMenu config file: EDIT /mnt/onboard/.adds/nm/config.txt Code:
menu_item :main :fbpad :cmd_spawn :quiet:/mnt/onboard/.adds/koreader/scripts/fbpad /bin/sh 0</dev/tty1 chain_success :dbg_toast :Started fbpad chain_failure :dbg_toast :Error menu_item :main :Stop fbpad :cmd_spawn :quiet:/usr/bin/pkill fbpad chain_success :dbg_toast :Stopped fbpad chain_failure :dbg_toast :Error Power off your Kobo. When you restart it, set USB host mode, plug in your powered USB connected keyboard, run fbpad from NickelMenu, and type (may stall). ***** CORRECTION FOR MORE STABLE OPERATION: DO NOT EDIT /sbin/kobo_getty.sh. RETURN IT TO ORIGINAL STATE, e.g.: Code:
#!/bin/sh [ -e /dev/ttymxc0 ] && /sbin/getty -L ttymxc0 115200 vt100 [ -e /dev/ttyS0 ] && /sbin/getty -L ttyS0 0 vt100 #[ -e /dev/tty1 ] && /sbin/agetty -s 38400 -t 600 tty1 vt100 INSTEAD EDIT /etc/inittab to add the agetty line only: Code:
::sysinit:/etc/init.d/rcS ::respawn:/sbin/kobo_getty.sh ::once:/sbin/agetty -s 38400 -t 600 tty1 vt100 ::ctrlaltdel:/sbin/reboot ::shutdown:/etc/init.d/rcK ::restart:/sbin/init ***UPDATE*** See POST #7 for a better way of doing this. Avoids the most system file meddling, but you will have to kill agetty again each time you return to Nickel after exiting KOReader. *** Edit NickelMenu config file to add Stop agetty command: EDIT /mnt/onboard/.adds/nm/config.txt Code:
menu_item :main :fbpad :cmd_spawn :quiet:/mnt/onboard/.adds/koreader/scripts/fbpad /bin/sh 0</dev/tty1 chain_success :dbg_toast :Started fbpad chain_failure :dbg_toast :Error menu_item :main :Stop fbpad :cmd_spawn :quiet:/usr/bin/pkill fbpad chain_success :dbg_toast :Stopped fbpad chain_failure :dbg_toast :Error menu_item :main :Stop agetty :cmd_spawn :quiet:/usr/bin/pkill agetty chain_success :dbg_toast :Stopped agetty chain_failure :dbg_toast :Error Power off your Kobo. When you restart it, set USB host mode, plug in your powered USB connected keyboard, run Stop agetty, then fbpad from NickelMenu, and type (shouldn't stall).

OSCREEN KEYBOARD
MAKING AN ONSCREEN KEYBOARD FOR OUR TERMINAL:
Fbkeyboard is a framebuffer keyboard that we can port to Kobo's fbink library, following the fbpad-eink example. $ mkdir fbkeyboard-build $ cd fbkeyboard-build/ *** First we build fbpad as in the previous post, except we leave some rows empty at the bottom of the screen for the keyboard. Assuming you have already built KOReader's koxtoolchain, NiLuJe's FBInk library, and Aligrudi/Droske's fbpads as before: $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ unzip fbpad-eink-master.zip $ cd fbpad-eink-master/ $ cp -r ../FBInk-v1.25.0/Release FBInk/ $ cp ../FBInk-v1.25.0/fbink.h FBInk/ (First make fbpadkbS, the small font version of fbpad for onscreen keyboard.) $ nano -l conf.h Code:

25 rows = fb_rows() * 29 / 51 / fnrows; Copy the fbpadkbS binary to the /mnt/onboard/.adds/koreader/scripts/ folder on your Kobo. (Now make fbpadkb, the large font version of fbpad for onscreen keyboard.) $ cp ../fbpads-master/fbpad_mkfn/ar.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ai.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ab.tf fonts/ $ nano -l conf.h Code:

ERRORS SO FAR
ERRORS SO FAR
I think I should dedicate a post to errors since I am so error-prone. * I do not do this on purpose to torture you - sometimes things work only on my Clara that I discover later, e.g. by clean install on new SD card! CRITICAL STEP (or /sbin/agetty won't run): # cp /mnt/onboard/.adds/koreader/libs/ld-musl-armhf.so.1 /lib/ This is the the same loader ld-musl-armhf.so.1 from the elinks install in a previous post. Obviously if I am running binary from /sbin without the library path of /mnt/onboard/.adds/koreader/libs/, then I need to supply the loader in the base /lib/ directory. I did not realize that I had done this on my Clara some months ago. Your fbpad w/USB keyboard won't work without starting and pkilling agetty (or equivalent). IMPORTANT NOTE: ON MY KOBO, EITHER USB OR WIFI NETWORKING (WHETHER CONNECTED TO HOTSPOT OR NOT) HAD TO BE ENABLED OR DEVICE FREEZES (when running fbkeyboard). WHO KNOWS WHY? SORRY FOR ANY FRUSTRATION - I HAD DONE MANY SUCCESSFUL TESTS NOT REALIZING THAT ENABLING WIFI WAS RELEVANT! Somewhere I renamed fbpads in my upload to fbpadS in my NickelMenu entries. That might cause error... Anything else?Hopefully that's it. *** CAUTION: You know how Nickel does all that background work when you connect USB cable to desktop, click "connect", then later unmount? Well, there may be a risk of data corruption if you had a loop mounted file, e.g. Alpine chroot. https://www.mobileread.com/forums/sh...38&postcount=2 So better don't try this. But if you DO connect a USB cable, either exit the chroot and unmount the loop first, OR click "cancel" and use SSH/Telnet networking instead.

If you are in SideloadedMode=true, then Activity tab is second from left at bottom of screen. Oskansi keyboard can be started and stopped from NickelMenu and unlike fbkeyboard, doesn't require networking, as well as being much faster, due to sending ANSI codes with IOCTL calls instead of simulating input events with uinput. The biggest issue might be that nothing appears on the fbpad screen due to e.g. oskansi sending codes to /dev/pts/0 but fbpad being on /dev/pts/1, but that shouldn't happen if you start oskansi before any other SSH session. *Also pls see *UPDATE below for NickelMenu entry. *** And don't forget to copy the keymap1-en_us.json, keymap2-en_us.json, and Roboto-Medium.ttf files to the /mnt/onboard/.adds/koreader/ folder of your Kobo. Oskansi binary or fbmenu.sh script should be in /mnt/onboard/.adds/koreader/scripts/ folder. If you're using the fbmenu.sh script above to launch oskansi, you need: 1) NickelDBus installed https://www.mobileread.com/forums/sh...ht=nickel+dbus 2) A NickelMenu config entry like: menu_item :main :fbmenu :cmd_spawn :quiet:exec /mnt/onboard/.adds/koreader/scripts/fbmenu.sh chain_success :dbg_toast :Started fbmenu chain_failure :dbg_toast :Error If you're not using the fbmenu.sh script, you could try NickelMenu config entries like: menu_item :main :fbpadkb :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbpadkb /bin/sh 0</dev/tty1 chain_success :dbg_toast :Started fbpadkb chain_failure :dbg_toast :Error starting fbpadkb menu_item :main : oskansi :cmd_spawn :quiet:exec /mnt/onboard/.adds/koreader/scripts/oskansi chain_success :dbg_toast :Started oskansi chain_failure :dbg_toast :Error *** UPDATE *** * The NickelMenu command (if not using fbmenu.sh) for oskansi should be: menu_item :main : oskansi :cmd_spawn :quiet:export HOME="/mnt/onboard/.adds/koreader/" && cd "$HOME" && /mnt/onboard/.adds/koreader/scripts/oskansi This is because oskansi looks for the font and .json files in the current folder, which would be / by default, so it wouldn't find them if you put them in /mnt/onboard/.adds/koreader/ . *** And grab the fbpadkb.bin binary from Post #6 above and rename it fbpadkb. You need to run this before oskansi. You do not need the agetty hack from Post #7 above, and can comment out the line in /etc/udev/rules.d/90-fbpad.rules unless you are using fbpad with a USB keyboard. Note that the CTL key in oskansi is a toggle so if you forget to retap it you may get funny characters. Though it only works with alphabetic characters. ALT key is a dummy key - maybe someone will want to activate it one day! *** *UPDATE2* Unfortunately, setting "EnableDebugServices=false" in [DeveloperSettings] in the /mnt/onboard/.kobo/Kobo/Kobo eReader.conf file, stopped oskansi keyboard from talking to fbpadkb. Fortunately, you just need to run Dropbear or even telnet from NickelMenu beforehand, and then oskansi works again. https://www.mobileread.com/forums/sh...d.php?t=353810 So it seems that: -fbpad with USB keyboard needs agetty started and stopped in order to not stall. -fbkeyboard needs WiFi on (or USB networking connected), though no hotspot connection needed, in order to not eventually freeze. -oskansi needs either "EnableDebugServices=true" or dropbear/telnet started beforehand via NickelMenu in order to communicate with fbpad. *** * Must rename oskansi.zip to oskansi.xz and extract with xz -d.

FBPAD2 - WITH USER-CONFIGURABLE FONT AND PERCENTAGE OF DISPLAY
***
FBPAD2 - WITH USER-CONFIGURABLE FONT AND PERCENTAGE OF DISPLAY One fbpad to do the job of four. fbpad -> fbpad2 fbpadS -> fbpad2 -f RobotoMono-MediumS.tf fbpadkb -> fbpad2 -p 58 fbpadkbS -> fbpad2 -f RobotoMono-MediumS.tf -p 58 * fbpad2 is just a working title - I guess the actual name should be fbpad-eink-rev2 or something. *** From FBInk build of Post #4 above: $ unzip fbpads-master.zip $ cd fbpads-master/ $ cd fbpad_mkfn/ $ make Grab some fonts e.g.: RobotoMono-Medium.ttf GWMonospace.ttf Generate small fonts for fbpadkbS: $ nano -l gen.sh CODE] 5 # OP="-h34 -w19" 6 # SZ="18h135v135" 7 OP="-h26 -w14" 8 SZ="18h100v100" 9 ./mkfn_ft $OP $FP/RobotoMono-Medium.ttf:$SZ >RobotoMono-MediumS.tf 10 ./mkfn_ft $OP $FP/GWMonospace.ttf:$SZ >GWMonospaceS.tf [/CODE] $ ./gen.sh tinyfont[ 875]: height=26 width=14 tinyfont[ 2858]: height=26 width=14 Generate large fonts for fbpadkb: $ nano -l gen.sh CODE] 5 OP="-h34 -w19" 6 SZ="18h135v135" 7 # OP="-h26 -w14" 8 # SZ="18h100v100" 9 ./mkfn_ft $OP $FP/RobotoMono-Medium.ttf:$SZ >RobotoMono-Medium.tf 10 ./mkfn_ft $OP $FP/GWMonospace.ttf:$SZ >GWMonospace.tf [/CODE] $ ./gen.sh tinyfont[ 875]: height=34 width=19 tinyfont[ 2858]: height=34 width=19 $ ls -l *.tf -rw-r--r-- 136976 courr.tf -rw-r--r-- 322024 RobotoMono-MediumS.tf -rw-r--r-- 568774 RobotoMono-Medium.tf -rw-r--r-- 1051768 GWMonospaceS.tf -rw-r--r-- 1857724 GWMonospace.tf $ cd .. $ cd .. $ tar xJf FBInk-v1.25.0.tar.xz $ cd FBInk-v1.25.0/ $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ make static $ cd .. $ unzip fbpad-eink-master.zip $ cd fbpad-eink-master/ $ cp -r ../FBInk-v1.25.0/Release FBInk/ $ cp ../FBInk-v1.25.0/fbink.h FBInk/ $ cp ../fbpads-master/fbpad_mkfn/*.tf fonts/ *** $ nano -l Makefile Code:

Then you need to enter ALT-c from keyboard to start a shell, list tags with ALT-p, and switch terminals with ALT-x, where x can be one of the terminals listed in conf.h, i.e. "xnlhtr01uiva-". Run fbpad2 from an SSH session. # fbpad2 -p 63 -s 37 0</dev/tty1 & # fbkeyboard2 -c 99 -g Enter ALT-c and you get the shell prompt on the Kobo display. Enter ALT-p and you get the tags list at the bottom of the screen, e.g.: TAGS: (x) n l h t r 0 1 u i v a - Enter ALT-n then ALT-p, the tags list shows you have switched to terminal (n): TAGS: x (n) l h t r 0 1 u i v a - Enter ALT-c and enter a command e.g. "ls"<RET> Enter ALT-x then ALT-p, the tags list shows you have switched back to terminal (x): TAGS: (x) n l h t r 0 1 u i v a - Enter a command e.g. "lsof"<RET> Enter a command e.g. "ps"<RET> Enter ALT-, and you scroll up. Enter ALT-. and you scroll down. CTRL-ALT-q to end the fbpad session. CTRL-ALT-x to end the fbkeyboard session. Now try fbpad2 with the shell command as a command line argument. # fbpad2 -p 63 -s 37 /bin/sh 0</dev/tty1 & # fbkeyboard2 -c 99 -g Now the terminal appears without needing to enter ALT-c. However the tag commands no longer work and you cannnot use CTRL-ALT-q to end the fbpad session. (However you can still use "pkill fbpad" then CTRL-ALT-x to end the fbkeyboard session.)

FBKEYBOARD2 - improved key mappings + rotate modes
***
FBKEYBOARD2 - improved key mappings + rotate modes *** Notice that the Esc key causes the Kobo to go into sleep mode, which is a problem if we want to enter command mode in Vi, or call up the menu in elinks. Until we address Kobo's grabbing of the input in various other ways, we can still get by with: 1) Ctrl-c in Vi can also be used instead of Esc to enter command mode. 2) We can remap the 'm' key instead of Esc in elinks to open the menu. In Post #4 we already remapped some elinks keys by appending to the elinks config file: $ nano -l /mnt/onboard/.adds/koreader/.elinks/elinks.conf Code:
################################## # Automatically saved keybindings # bind "main" "Ctrl-F" = "frame-next" bind "main" "Ctrl-B" = "frame-prev" bind "main" "," = "history-move-back" bind "main" "." = "history-move-forward" bind "main" "u" = "link-info" bind "main" "Alt-l" = "lua-console" bind "main" "Down" = "move-cursor-down" bind "main" "Left" = "move-cursor-left" bind "main" "Right" = "move-cursor-right" bind "main" "Up" = "move-cursor-up" bind "main" "Tab" = "move-link-next" bind "main" "Shift-Tab" = "move-link-prev" bind "main" "#" = "toggle-numbered-links" bind "main" "Ctrl-Right" = "none" Up,Down,Left,Right -> move cursor Tab,Shift-Tab -> travel links on a page . -> go forward in history , -> go back in history Some handy default key mappings are: Space -> page down b -> page up [ or { -> scroll left ] or } -> scroll right. Enter to edit a text field, d -> download link a -> add bookmark s -> show bookmarks Esc -> main menu g -> enter new address or '.' for current directory q -> quit T -> open in new tab <,> -> go to previous,next tab c -> close tab W -> wrap text In the numeric layout of fbkeyboard.c, there are some empty key slots after the '/', which if pressed, currently yield "cvbnm". We will assign "aswtc" to them in char *layout[] and in keys[][26] so that in elinks we can access when in the numeric keyboard layout: a -> add bookmark s -> show bookmarks w -> wrap text t -> open in new tab c -> close tab To do this we will further append to the elinks config file as follows: $ nano -l /mnt/onboard/.adds/koreader/.elinks/elinks.conf Code:
################################## # Automatically saved keybindings # bind "main" "Ctrl-F" = "frame-next" bind "main" "Ctrl-B" = "frame-prev" bind "main" "," = "history-move-back" bind "main" "." = "history-move-forward" bind "main" "u" = "link-info" bind "main" "Alt-l" = "lua-console" bind "main" "Down" = "move-cursor-down" bind "main" "Left" = "move-cursor-left" bind "main" "Right" = "move-cursor-right" bind "main" "Up" = "move-cursor-up" bind "main" "Tab" = "move-link-next" bind "main" "Shift-Tab" = "move-link-prev" bind "main" "#" = "toggle-numbered-links" bind "main" "Ctrl-Right" = "none" # bind "main" "w" = "toggle-wrap-text" bind "main" "t" = "open-link-in-new-tab" bind "main" "m" = "menu" Also in fbkeyboard2, we will reassign top row keys when in CAPS LOCK mode from Up, Down, Left, Right, and PageDown to accelerated (4 x) direction keys,and PageUp.

The default use of 'm' followed by a character, e.g. 'a' allows you to save your place in the document, and return to it by entering "'" then your character , e.g. 'a'. bind "main" "e" = "menu" bind "main" "S" = "save-as" bind "main" "Ctrl-o" = "open-os-shell" Use 'E' to open current link under cursor into a text field. (Or 'S' for current URL.) Use "Ctrl-x" to copy link. Use "Ctrl-v" to paste link. *** Using Screen utility for copy-pasting: The screen app has only the following dependencies: Depends (4) libutempter musl* ncurses-libs* utmps-libs *already got these from elinks/nano install in Post #3.

RUN THESE FROM FBPAD2/FBKEYBOARD2 TERMINAL: # . /korenv.sh # screen (Press Ret to dismiss message) # elinks . enter 'g' to open new URL enter e.g. "g elinks doc" click on the link, e.g. "http://elinks.or.cz/documentation/index.html" enter 'a' to add to bookmarks enter 's' to show bookmarks Use the arrow keys to move to a link you want, e.g. "Documentation" Use 'E' to open current link under cursor into a text field. (Or just 'S' to open current URL.) Use "Ctrl-x" to copy link. Use "Ctrl-v" to paste link. Cancel to exit the dialog. Enter "Ctrl-a" and then 'c' to open a new screen window. Type the name of a command, e.g. 'echo > try.txt "' followed by "Ctrl-a" and then ']' and '"' and you get the text pasted to the file: # cat try.txt http://elinks.or.cz/documentation/index.html (Was it worth the effort. i.e.you could have just saved as a bookmark, then retrieved the link from /mnt/onboard/.adds/koreader/.elinks/bookmarks!) Move back and forth between screen terminals with "Ctrl-a" and then '0' or '1', or just "Ctrl-a" "Ctrl-a". Enter 'q' to exit elinks. "Ctrl-a" and then '\' to kill all windows and terminate screen. *** Some time later... OK definitely worth it for me anyway. Check this out: On your Kobo: # . /korenv.sh Create a sample html file with a form field: # nano text.html Code:

blablabla hahahaha wawawa Enter "Ctrl-n" or "Ctrl-p" to get to the start line you want, then Space (no 'Ctrl') to start the copy. Enter "Ctrl-n" or "Ctrl-p" to get to the end line you want, then Space (no 'Ctrl') to complete the copy. Enter "Ctrl-a" then '0' (no 'Ctrl') to return to the first screen window. Press Enter in the text box, then "Ctrl-a" then ']' (no 'Ctrl') to paste the text from the second window. Screen also allow off-screen scrolling in copy mode using the same "Ctrl-n" or "Ctrl-p" keys. Just remember not to press any other key,or it will be aborted.(Maybe "Ctrl-h" is permitted.) (Must stay aware of the 'Ctrl' key toggle state.) In this way I could even run 'ps' and copy offscreen process names like "/usr/local/kfmon/bin/kfmon" to the other window. Enter "Ctrl-a" then 'd' (no 'Ctrl') to detach from the session. Run KOReader. From KOReader Terminal: # screen -r And you are back in! "Ctrl-a" and then 'k' to kill window. *** *UPDATE2 - LOWKEY PROFILES FOR MORE DISPLAY SPACE $ nano -l fbkeyboard.c Code:

MIGRATE TO NEW /mnt/onboard/.adds/kordir/ FOLDER
***
MIGRATE TO NEW /mnt/onboard/.adds/kordir/ FOLDER Originally, the /mnt/onboard/.adds/koreader/scripts/ folder was a handy place to install elinks so we could run it from KOReader terminal. But it has gotten cluttered, and we have added many apps like fbpad that are not even run from KOReader terminal, not to mention some libfile clashes that have come up. So we will move everything to the /mnt/onboard/.adds/kordir/ folder and point the /korenv.sh script there. Note that you would now have to run ". /korenv.sh" from KOReader terminal to set the PATH and LD_LIBRARY_PATH, same as in fbpad, since it is no longer the default KOReader path. # cd /mnt/onboard/.adds/ # mkdir kordir # mkdir kordir/scripts # mkdir kordir/libs POST #3 FILES: # cd /mnt/onboard/.adds/koreader/scripts/ # mv elinks nano wgets w3m moon-buggy ttyper chalpine.sh chalpined.sh fbink /mnt/onboard/.adds/kordir/scripts/ # cd /mnt/onboard/.adds/koreader/libs/ # mv ld-musl-armhf.so.1 libbz2.so.1 libc.musl-armv7.so.1 libcrypto.so.3 libexpat.so.1 libssl.so.3 libformw.so.6 libmenuw.so.6 libncursesw.so.6 libpanelw.so.6 libidn2.so.0 libunistring.so.5 libpcre2-8.so.0 libpcre2-posix.so.3 libcord.so.1 libgc.so.1 libstdc++.so.6 libfbink.so.1 /mnt/onboard/.adds/kordir/libs/ # mv w3m/ /mnt/onboard/.adds/kordir/usr/lib/ Copy your cert.pm and certs/ca-certificates.crt to the /etc/ssl/ directory.

OSKANSI2 - NEW KEYDEFS, EXTRA LAYOUTS, AUTO DISPLAY SIZE, GRAB INPUT
***
OSKANSI2 - NEW KEYDEFS, EXTRA LAYOUTS, AUTO DISPLAY SIZE, GRAB INPUT Some new key definitions available: "DEL","INS","HOME","END" "F1" - "F10" (though who knows if they work properly) "EXIT" (kills oskansi - handy if OSK_GRABIN is set.) "SYM" (Brings up Symbol keyboard layout.) "S0" - "S99" (Extra symbol layouts can be defined.) "ALT" (Really just sends an escape character before any normal character, i.e any character with "keyType"= 0. Will switch off after each character, i.e. ALT-a ALT-b requires two ALT key presses.) "CTL" (Works only on a-z and A-Z. Now switches off after each character , like ALT.) "TAB" (Now properly changes to SHIFT-TAB when "CAP" active.) "CAP" (Now can be pressed twice consecutively without needing to press an intervening key.) Oskansi2 can work with the same keyboard layout JSON files as the original oskansi (keymap1-en_us.json, keymap2-en_us.json), EXCEPT they now must be renamed to: osk-keymap-LC.json osk-keymap-UC.json Plus you can have an optional symbol layout: osk-keymap-S0.json You can add additional symbol layouts (S1-S99) if you configure it in a configuration file: osk-keymap-conf.json The same configuration file can be used to define fonts and programmable key macros. Otherwise the font defaults to the same as it was for oskansi: Roboto-Medium.ttf For those concerned about the security aspect, programmable key macros are disabled in the three main layouts: osk-keymap-LC.json osk-keymap-UC.json osk-keymap-S0.json Examples of configuration file and symbol layouts are attached. *** LANDSCAPE and PORTRAIT refer to NickelMenu entries: # Nickel_Orientation Actions menu_item : main : Orientation - LANDSCAPE - handle above : nickel_orientation: landscape menu_item : main : Orientation - PORTRAIT - handle on right : nickel_orientation: portrait Using with device in LANDSCAPE: # OSK_XIN=1 OSK_YIN=3 OSK_HEIGHT=1000 OSK_REGEN=1 OSK_GRABIN=1 oskansi2 Back in PORTRAIT: # oskansi2 Now has offset keyboard because still using the previous png files, so reset the env variables: # OSK_XIN=4 OSK_YIN=1 OSK_HEIGHT=0 OSK_REGEN=1 OSK_GRABIN=0 oskansi2 The layout png files are regenerated for portrait. Now run without regen: # oskansi2 Startup is fast without having to regenerate layout png images. EXPLANATION: The koboin.go input handler library was modified to handle a few experimental environmental variables, namely: OSK_XIN, OSK_YIN: Set input orientation for x, y, to one of the following values: 1 -> x 2 -> reverse x 3 -> y 4 -> reverse y If these variables are left undefined, they will default to the input orientation for the Clara HD in portrait mode, i.e. OSK_XIN=4 and OSK_YIN=1. OSK_GRABIN: Grab input from /dev/input/event1. Nickel elements on the display no longer respond to touch. Additional environment variables are handled by main.go: OSK_WIDTH: Sent to osk.go and koboin.go to set display width. OSK_HEIGHT: Sent to osk.go and koboin.go to set display height. You can probably leave OSK_WIDTH and OSK_HEIGHT undefined, since oskansi2 now sets them to values returned by libFBInk (In previous oskansi they were hardcoded values similar to Clara HD size.) This means oskansi2 could now in theory display properly on any Kobo device - but I don't have devices to test. However, I can now run it in LANDSCAPE mode (provided I modify the OSK_XIN and OSK_YIN input orientation variables to match, found by trial and error). That said, it can be helpful to tweak the OSK_HEIGHT value to slightly less than full-height, so as to leave a margin between keyboard and Nickel buttons at the bottom of the display (not too much or the touch alignment is skewed), if not grabbing input. OSK_REGEN: Recreate all keyboard layout png images from JSON files. This is important if you have made changes to all the JSON files (or changed between PORTRAIT/LANDSCAPE orientation.) Otherwise oskansi2 will continue to use the existing png file and not reflect your changes. However, if you have 98 layouts and only change the 99th JSON file, it makes more sense to just delete the png file #99 instead of using OSK_REGEN to recreate all 99 png files. OSK_TTY: Set input tty to arbitrary input device, i.e. /dev/tty1. This is helpful when fbpad is not running in the default (originally /dev/pts/0) tty expected by oskansi, usually because an ssh session had been run before. Actually, oskansi2 has now been modified to look for $OSK_TTY first, then /dev/tty1., and then /dev/pts/0, so you can probably leave OSK_TTY undefined. OSK_FONTMAIN: Override default font of Roboto-Medium.ttf OSK_VERBOSE: Sends messages to fb, in addition to console. The relevant changes to ~/go/src/github.com/shermp/go-kobo-input/koboin/koboin.go: Code:
... "os" "strconv" // #include <linux/input.h> "C" "syscall" "unsafe" ) const ( EVIOCGRAB = C.EVIOCGRAB ) var envstr string var xin int var yin int ... // New creates a new TouchDevice struct and returns it to the caller func New(inputPath string, vWidth, vHeight int) *TouchDevice { t := &TouchDevice{} f, err := os.OpenFile(inputPath, os.O_RDONLY, os.ModeDevice) if err != nil { fmt.Println("Could not open device for reading") return nil } t.devFile = f // Grab input if OSK_GRABIN set from env envstr = os.Getenv("OSK_GRABIN") fmt.Println("OSK_GRABIN is: ", envstr) var grabin, _ = strconv.Atoi(envstr) if (grabin > 0) { grabin = 1 } else { grabin = 0 } if (grabin > 0) { grab1 := int(1) _, _, eno := syscall.Syscall(syscall.SYS_IOCTL,f.Fd(),uintptr(EVIOCGRAB) ,uintptr(unsafe.Pointer(&grab1)),) if eno != 0 { fmt.Println("OSK_GRABIN error: ", eno) } } // Read input orientation from env envstr = os.Getenv("OSK_XIN") xin, _ = strconv.Atoi(envstr) envstr = os.Getenv("OSK_YIN") yin, _ = strconv.Atoi(envstr) t.viewWidth = vWidth t.viewHeight = vHeight return t } ... // GetInput returns the rotated x, y coordinates of where the user touches func (t *TouchDevice) GetInput() (rx, ry int, err error) { ... /* Coordinate rotation needs to happen. For reference, from FBInk, a clockwise rotation is as follows: rx = y ry = width - x - 1 But we need to rotate counter-clockwise... */ ry = x if (yin > 0 && yin < 5) { if (yin == 1) { ry = x } else if (yin == 2) { ry = t.viewHeight - x + 1 } else if (yin == 3) { ry = y } else if (yin == 4) { ry = t.viewWidth - y + 1 } } rx = t.viewWidth - y + 1 if (xin > 0 && xin < 5) { if (xin == 1) { rx = x } else if (xin == 2) { rx = t.viewHeight - x + 1 } else if (xin == 3) { rx = y } else if (xin == 4) { rx = t.viewWidth - y + 1 } } return rx, ry, nil } Other coding changes were made to: ~/go/src/github.com/shermp/go-osk/osk/osk.go ~/go/src/github.com/shermp/go-kobo-input/koboin-osk-sample/main.go (see attached source files) *** USAGE: Assuming you had moved everything to the /mnt/onboard/.adds/kordir/ folder as in previous post #14: Copy and decompress the attached oskansi2 binary to the /mnt/onboard/.adds/kordir/scripts/ folder. Copy and decompress the following to the /mnt/onboard/.adds/kordir/ folder: Roboto-Medium.ttf keymap1-en_us.json keymap2-en_us.json Set the path and move to /mnt/onboard/.adds/kordir/ folder: # . /korenv.sh You can run oskansi2 with these oskansi json files, but you have to rename them: # cp keymap1-en_us.json osk-keymap-LC.json # cp keymap2-en_us.json osk-keymap-UC.json First run fbpad2: # fbpad2 -p 58 /bin/sh 0</dev/tty1 & Now run oskansi2 with OSK_REGEN to build the png images: # OSK_REGEN=1 oskansi2 (Ctl-C to exit, or try the new EXIT key.) To try the new symbol layout, copy and decompress the following to the /mnt/onboard/.adds/kordir/ folder: osk-keymap-LC.json osk-keymap-UC.json osk-keymap-S0.json Now run oskansi2 with OSK_REGEN to build the png images: # OSK_REGEN=1 oskansi2 (Ctl-C to exit, or try the new EXIT key.) To try the extra symbol layouts and programmable key macros, copy and decompress the following to the /mnt/onboard/.adds/kordir/ folder: RobotoMono-Medium.ttf osk-keymap-S1.json osk-keymap-S2.json osk-keymap-conf.json Now run oskansi2 with OSK_REGEN to build the png images: # OSK_REGEN=1 oskansi2 (Ctl-C to exit, or try the new EXIT key.) * Note that the S2 layout is only 2 rows high, but you can press the SYM key to get back to the regular layout. It's a good idea to have a separate directory for running oskansi2 in LANDSCAPE mode, so as not to have to regenerate the png image files each invocation. # mkdir landscape # cd landscape/ Copy all the above files to /mnt/onboard/.adds/kordir/landscape/, put device in LANDSCAPE and restart fbpad2: # OSK_XIN=1 OSK_YIN=3 OSK_REGEN=1 OSK_GRABIN=1 oskansi2 You can do all this from NickelMenu with entries like: menu_item :main :fbpad2 -p 58 :cmd_spawn :quiet :/mnt/onboard/.adds/kordir/scripts/fbpad2 -p 58 0</dev/tty1 chain_success :dbg_toast :Started fbpad2 chain_failure :dbg_toast :Error starting fbpad2 menu_item :main : oskansi2 :cmd_spawn :quiet:export HOME="/mnt/onboard/.adds/kordir/" && cd "$HOME" && OSK_GRABIN=1 /mnt/onboard/.adds/kordir/scripts/oskansi2 chain_success :dbg_toast :Started oskansi2 chain_failure :dbg_toast :Error LANDSCAPE and PORTRAIT refer to NickelMenu entries: # Nickel_Orientation Actions menu_item : main : Orientation - LANDSCAPE - handle above : nickel_orientation: landscape menu_item : main : Orientation - PORTRAIT - handle on right : nickel_orientation: portrait menu_item :main : oskansi2 landscape :cmd_spawn :quiet:export HOME="/mnt/onboard/.adds/kordir/" && cd /mnt/onboard/.adds/kordir/landscape/ && OSK_XIN=1 OSK_YIN=3 OSK_GRABIN=1 /mnt/onboard/.adds/kordir/scripts/oskansi2 chain_success :dbg_toast :Started oskansi2 chain_failure :dbg_toast :Error menu_item :main :fbpad2 -p 80 elinks :cmd_spawn :quiet :export HOME="/mnt/onboard/.adds/kordir/" && cd "$HOME" && export PATH="$PATH:/mnt/onboard/.adds/kordir/scripts" && export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/mnt/onboard/.adds/kordir/libs" && fbpad2 -p 80 elinks . 0</dev/tty1 chain_success :dbg_toast :Started fbpad2 chain_failure :dbg_toast :Error starting fbpad2 Note that if you run "fbpad2 -p 58 0</dev/tty1" like in the above entry, as opposed to "fbpad2 -p 58 /bin/sh 0</dev/tty1" (with the "/bin/sh"), you have to enter ALT-c from the keyboard to activate the shell. Maybe even repeat and press RET. Unsure if the same kind of issues crop up like in UPDATE2 at the end of Post #10... * Must rename oskansi2.zip to oskansi2.xz and extract with xz -d. *** Last edited by elinkser; 03-17-2024 at 04:33 PM. |
