What happened to the ePub script?

What happened to the ePub script?

[Henning Hraban Ramm]

Hi,
with the latest betas, the ePub script doesn’t work anymore.
Regardless with which file I call it, I get only:


$ mtxrun --script mtx-epub --make solo

resolvers       | caching | skipping 'files' for 'home:texmf' from '/Users/hraban/Library/texmf/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/trees/54be04d87dd160089f572b19cb5c97e9' (version mismatch)
mtx-epub        | unknown specificaton file for 'solo'


Previously, you didn’t need to call it with any specification file, but only with a plain ConTeXt file like


\setupbackend[
	export=export.xml,xhtml=yes,
]
\setupexport[
	firstpage={koe.png},
]
\settaggedmetadata[
	author={Hraban},
]


\starttext

\startchapter[title={Chapter One}]

\startsection[title={Section One}]

\input tufte

\stopsection

\startsection[title={Section Two}]

\input knuth

\externalfigure[koe][width=\textwidth]

\stopsection

\stopchapter

\stoptext


An export.specification file was previously created by the script, I don’t know (anymore) for what. Calling the script with one of those also doesn’t do anything.

just use:

\setupbackend[export=yes]

all happens in dedicated sub directories now

<jobname>-export
<jobname>-epub

also, there have been some changes in the output (more detail in 
sectioning and so i.e. chains and levels) ... just look at the files 
produced

there is also div based output

I know, but it seems I have to recreate my whole workflow again.

Didn’t have enough time to look into everything in detail, but if I just run the epub script after the context run, it fails:


$ mtxrun --script epub --make solo

I’ll investigate further tomorrow.

Thanks, but the image isn’t missing!?

Re: What happened to the ePub script?

[Henning Hraban Ramm]

Hi there,

I started documenting ConTeXt’s current ePub/export behaviour in http://wiki.contextgarden.net/ePub and will merge/delete the content of the current wiki pages as soon as I’m content with its content ;)

* Do you think it would be better to document export and ePub separately?


Of course I have questions, e.g.:

* How can I set the current \date in a metadata variable?
(I know it’s also in the date tag of <document>, but I know how to format \date …)

This doesn’t work (i.e. I get „\date“ in XML/XHTML):

\settaggedmetadata[
	version={\date}
]

* Can I influence the directory/file names of the export from within the source?
E.g. if I compile „minimal.tex“, I get minimal-export and minimal-epub
The —result switch doesn’t change anything.

* BTW: Can I set —result from within my ConTeXt source?

More to follow ;)

	Especially, if you want to be thorough.

Already did the split after sending my previous message, so there’s now ePub and http://wiki.contextgarden.net/Export

I’ll probably create more pages on specific ePub topics like images and cover pages.

hm, honoring --result is doable but in general i'd like to keep the 
export quite basic and predictable (the less options the better)

no, because the context script also does some cleanup and checking (like 
not replacing the tuc file when there is an issue)

(letting tex influence its own run is somewhat tricky and has limitations)

Thanks, but that’s not the same. Not only because I get „2015-1-20“ and not „2015-01-20“.

Is there a way to get „everything“ expanded within \settaggedmetadata ?

Ok, that means we have no influence on files names at all?

Ok, would have been nice. Will write a wrapper script for my use case.

no, because \hbox{foo\smallcaps bar\kern10pt gnu} and such have no real 
string representation

it would only be the directory and maybe the main files but not every 
specific file (it would demand an extra setup and lots of explanations 
in the manual) but maybe at soem point the mtx-epub script can do some 
magic ... it's already tricky to keep up cq. satisfy basic epub 
standards and it's really no fun to do that kind of stuff ... i have no 
real need for it so i cannot spend ages on it ... (in fact i only redid 
it because i wanted to play with the svg math and then noticed some 
possible improvements in the rest

it it's systematic, predictable etc etc we can always add it as option 
but filenames and their use are pretty fragile in epub (i had no 
problems with crashing of locking the kobo)
