Thoughts on Potential New Features for Sigil

[KevinH]

Hi All,

I am looking for thoughts on new features for future versions of Sigil:

Here is a new feature I have been thinking about ...

Since epubcheck now reports on out of date or incorrect media types, I was thinking of:

A. adding a tool to BookBrowser to change the Media Type for a resource one at a time. Inside Sigil each resource object keeps its own media type internally, and of course there is the OPF manifest which also provides the media type so both have to be updated. Multiple selection in the BookBrowser would be possible.

or

B. adding a new Sigil Tool menu to automatically walk all manifest types updating them when older media types need to be updated to new ones.


The only issue with both option A or B is that of course you can convert a binary media-type to a text media type without losing anything if really needed but not visa-versa. Also what happens when the new media-type input from the user is actually has a different file format that what was provided in the OPF when first launched. That should not happen often but it could.


So I would love to hear from you to understand if either option A or B would be useful enough to add to Sigil itself instead or if you feel these things would be better as a plugin, or not useful at all.

Please use this thread to make other feature suggestions that might prove useful to the main body of Sigil users. Please try not to suggest things that have already been ruled out in earlier feature threads or that already exist in the form of a plugin.

Be sure to explain why you think your feature would benefit the majority of the users of Sigil.

Thanks.

How about a "Fix outdated/wrong media types" right-click Book Browser menu option that is only shown for .opf files?

Yes that should be doable and better than yet another menu item under Sigil Tools.

I would have liked a dedicated tool, which would offer many options, but a such use case would be absolutely rare. Apart from correcting wrong media types, altering the media type by anything other than that on of the file makes almost no sense and is of no use. And if you really wanted to do it, then you knew exactly what you were doing and didn't need such a tool.

So @Doitsu's proposal is really perfect. Simple, small and effective.
However, I recommend making this action accessible into the Automation tool.

The only hard case is pure xml files with the generic .xml file extension but no way to easily detect what type of xml is in the file. I could always leave them alone and not update those.

[BeckyEbook]

Or perhaps in the case of questionable .xml files, the choice of whether to treat them as pure xml or as “application/xhtml+xml”.

[KevinH]

Detecting html and doctype tags in a generic xml file should be quite easy to do. Those we can handle.

The other interesting case would be how to deal with media-types where they allow multiple media types for the same resource. Seems like Fonts and Javascripts are big with multiple names

Images
--------
image/gif  - GIF Images
image/jpeg - JPEG Images
image/png  - PNG Images
image/svg+xml - SVG documents
image/webp - WebP Images

Audio
-------
audio/mpeg - MP3 audio
audio/mp4 - AAC LC audio using MP4 container
audio/ogg - OPUS audio using OGG container

Style
------
text/css - CSS Style Sheets.

Fonts
------
font/ttf 
application/font-sfnt - TrueType fonts

font/otf
application/font-sfnt
application/vnd.ms-opentype - OpenType fonts

font/woff 
application/font-woff - WOFF fonts
font/woff2 - WOFF2 fonts

Other
------
application/xhtml+xml - XHTML content documents


application/javascript
application/ecmascript
text/javascript  - JavaScripts

application/x-dtbncx+xml - The legacy NCX.

application/smil+xml	- EPUB media overlay documents

I'd like the CSS mend/pretty to have an option to convert all measures that are effectively zero to 0;

In other words:

.someclass {
  margin-left: 0em;
  margin-right: 0px;
  margin-top: 0.0em;
  margin-bottom: 0;
}

would become:

.someclass {
  margin-left: 0;
  margin-right: 0;
  margin-top: 0;
  margin-bottom: 0;
}

This way, I can search and replace more easily. There's no good regex that covers all the ways to declare a measurement in CSS.

[KevinH]

I think a regex could do that quite easily. You do know that regex will allow the equivalent of an "or" right (em|px|…). And using the regex function replacement plugin could easily numerically evaluate any set of digits with decimal points to compare it to 0.

In Sigil, something like this works:

Find:

:(\s*)0(?:\.0+)?(?:em|px|rem|%|vh|vw|vmin|vmax|cm|mm|in|pt|pc)?(?=;|\s|$)

Replace:

: 0

I can't do any better, maybe I'm tired of the heat.

....although I would probably get rid of the : at the beginning in case there are any shorthand...eg margin: 0px 0em 0vw 0.0rem;

I obviously haven't tested this... (I'm taking a 'coke' break at work ) maybe it already does shorthand???

[BeckyEbook]

You are right! A quick test worked, but I still need to test it on larger samples.
Removing the colon simplifies things, although I started with it and stayed that way until the end.

[JSWolf]

With that CSS,

margin: 0px 0em 0 0%;

becomes

margin: 0 0em 0 0%;

It would be great if it were possible to select text with the mouse in other places (Wikipedia, newspapers), copy it and paste it into Sigil while retaining italics and bold.
