Possibile bug in Beautifier

senhal · 02-08-2016, 09:57 AM

When I apply Beautify, a code like this:

Code:

<h1>C<span class="smallcaps">HAPTER</span> O<span class="smallcaps">NE</span></h1>

became:

Code:

<h1>C

    <span class="smallcaps">HAPTER</span> O

    <span class="smallcaps">NE</span>

  </h1>

Before:

After:

Wrong spaces have been added

Am i doing something wrong?

I cannot reproduce this, copy pasting your example and running beautify, results in

Code:

<h1>C<span class="smallcaps">HAPTER</span> O<span class="smallcaps">NE</span></h1>

I'm Using Calibre 64bit 2.50.1 and Calibre 32bit (same version) on Windows 7.
They both give the same result.

Why not attach a complete epub showing the issue? Maybe 2 chapters; one pre beautify; one post beautify?

I have seen Similar before. I always assumed those few case were due to sloppy REGEX

when wrapping a Initial Letter or small cappin with a span.

It does not happen that often, so maybe the coder is using a non-breaking character at the Span to keep it from splitting the C from hapter

Here it is

Note that applying beautifier again and again, the space between lines increases.

Curious...
Only it happens when there is only one line of code inside <body>.
With two lines working properly.

Code:

  <h1>C<span class="smallcaps">HAPTER</span> O<span class="smallcaps">NE</span></h1>

  <h1>C<span class="smallcaps">HAPTER</span> O<span class="smallcaps">NE</span></h1>

Ah yes that will be because of a heuristic in the beautifier. Normally, the beautifier does not adjust code inside a block level tag, precisely because of the problem described here, except in the case of the block level tag being the only child of body, in which case it is assumed to be a wrapper tag. I suppose I can adjust the heuristic to also check the tag name and reject heading tags, since they are unlikely to be wrapper tags.

Oh, I see.
However, the same happens with:

Code:

<p>C<span class="smallcaps">HAPTER</span> O<span class="smallcaps">NE</span></p>

Yes, it will happen with any block level tag, as I explained before. It is a tradeoff, either one disables this functionality in which the common pattern of having all content in a top level wrapper tag will not be beautified or one accepts that int he rare case of html files having a single block level tag, the beautifier will insert extra spaces.
