Bug with stylesheet processing for EPUB...

Sunfox · 01-28-2016, 06:17 AM

I code my HTML by hand for use with both Kindlegen and Calibre, and for convenience my default stylesheet is not actually called "stylesheet.css".

In my HTML, I have the following specified as the only stylesheet:

Code:

<link rel="StyleSheet" type="text/css" href="_0-styles.css"/>

However, after converting to EPUB and running a check, despite everything looking perfect I get the following error:

Code:

The linked resource '_0-style.css' does not exist  [various files]

In looking deeper, the file _0-style.css is indeed not included in the file, because Calibre has renamed it to stylesheet.css. And in this renamed file, all of my custom styles from _0-style.css have been correctly included.

The problem is, in the resulting generated HTML, it is specifying both the NEW and the OLD, DELETED stylesheet. For example, I get this in the top of every file:

Code:

<link rel="StyleSheet" type="text/css" href="_0-styles.css"/>
<link href="stylesheet.css" rel="stylesheet" type="text/css"/>

Since Calibre is reading this file correctly and knows it won't be including the original, I don't know why it continues to include this line in all HTML.

I can work around the error either by needlessly including _0-styles.css (simplest), or by manually deleting the code from every HTML file (difficult due to splitting). Or, I suppose, by changing to using "stylesheet.css", but I name things this way to make mass coding/reuse a bit quicker and less disorganized for my workflow.

Is your CSS in the same directory as the XHTML files?

Sorry for totally spacing out on responding to this!

Yes, the CSS file is in the same folder, nothing fancy going on. Calibre is reading and processing the file's contents just fine... it's just failing to NOT write a reference to the now abandoned file in the finished code.

conversion does not rename stylesheets. It flattens all css and the result of that flattening is put into a new stylesheet.

And to have calibre remove the link to the old stylesheet, give it a correct rel value of "stylesheet" not "StyleSheet"
