epub transformation fails (in OxGarage) due to missing file "epub-print.css"

[peterstadler]

As reported on TEI-L, OxGarage fails to transform TEI -> ePub. The OxGarage error message is clear:

Error at char 23 in xsl:for-each/@select on line 222 column 86 of tei-to-epub.xsl:
FOUT1170: Failed to read input file: /usr/share/xml/tei/stylesheet/css/epub-print.css (No
such file or directory)

I thought this was already fixed by #394 but apparently only for epub3?! So I think a simple fix would be to have the relative links at

Stylesheets/epub/tei-to-epub.xsl

Lines 57 to 59 in b8db468

	<xsl:param name="cssFile">../css/tei.css</xsl:param>
	<xsl:param name="cssODDFile">../css/odd.css</xsl:param>
	<xsl:param name="cssPrintFile">../css/epub-print.css</xsl:param>

point at (absolute) URLs.

For the record see also #412, but IMHO that should not stop us from applying the proposed "hack".

I added the “needs discussion” tag, because I have some vague recollection about discussing whether we should maintain other epub formats besides epub3. I will add this to the agenda of our next meeting.

For the idea of deprecating epub in favor of epub3 see #576

This bug is also present in the Oxygen plugin.

I think we should remove the Makefile action that copies all the CSS into a different location, and then see what breaks; then we should fix those transformations so that they look in the correct location for the CSS files.

[peterstadler]

The Makefile target that copies the CSS files is common:

Stylesheets/Makefile

Lines 71 to 74 in c89f3c7

	common: names
	@echo BUILD Copy common files and documentation
	test -d release/xslcommon/xml/tei/stylesheet || mkdir -p release/xslcommon/xml/tei/stylesheet
	cp names.xml catalog.xml VERSION css/*.css i18n.xml release/xslcommon/xml/tei/stylesheet

common is a dependency of the release target:

Stylesheets/Makefile

Line 127 in c89f3c7

release: common doc oxygendoc build profiles

So, if we removed (or changed) the "copying of the CSS files" in the common target, we will get a different directory structure of the release artifact and finally of the deployed version at https://tei-c.org/release/xml/tei/stylesheet/ and within the Vault.

If we really needed to change anything here (see the idea of deprecating epub2 #576), my preferred approach would be to change the directory structure of the Stylesheets repo not the release.
