[NTG-context] ePUB creation problems
I’m getting to the next phase of ePUB creation. My project now exports and with
mtxrun —script epub, I can create an actual ePUB, but there are issues I need
to fix.
One is the lack of a cover image. The command for epub creation works, but says:
(. /usr/local/src/ConTeXt/tex/setuptex mtxrun --script epub --make
prd_book)
mtx-epub| using specification file 'prd_book-export/prd_book-pub.lua'
mtx-epub| the 'mudraw' binary is not present
mtx-epub| cover page image 'cover.xhtml' is not present
mtx-epub| saving dummy coverpage to 'prd_book-export/cover.xhtml'
I’m using in the env file:
\setupbackend
[export=yes]
\setupexport
[title={Chess and the Art of Enterprise Architecture},
author={Gerben Wierda},
firstpage={9789081984058-CoverFront.jpeg},
]
So, what seems to be ignored is
\setupexport
[title={Chess and the Art of Enterprise Architecture},
author={Gerben Wierda},
firstpage={9789081984058-CoverFront.jpeg},
]
What am I missing?

[NTG-context] Epub format Was: Re: Context to epub: itemize
Hi Axel, All, You have mentioned that most current ebook readers can not display MathML. Well, the problem lies in the epub guidelines for the readers. The problem is even worse. many readers do not even implement the full HTML5 standard. though that is the standard used in the latest epub stadnard. The fact is to be considered epub readers the do not have to, it is a problem of the epub reader definition. The problem is what should ConTeXt output? Should it output code that implements according to the full epub standard OR JUST what is handled by most epub readers! IMHO : ConTeXt should not output XHMTL for epub, but HMTL5. Yes, yes, I know XHMTL is part of HMTL5. Another question for me is if ConTeXt should also output code for the iBooks epub format, (Basicaly epub, but some extras). There are thing you can do in/with ConTeXt that would work with iBooks that do not in „ordinary“ epub books. Then, there is the Kindle format one might want to consider! Another, question which needs investigation is if the ConTeXt output for epub, also, implementing the fallbacks for missing features which is required? Just some added thoughts. Basically, you can only expect ConTeXts epub output to be a starting point that then has to be tweak. regards Keith.

Re: [NTG-context] EPUB XHTML Format
Hi, so, i'd never claim that context produces epub but it can be used in a workflow that involves epub as it outputs xml which can be transformed That's a distinction that either might not matter or sometimes is lost: http://tex.stackexchange.com/a/17642/2148 http://wiki.contextgarden.net/epub ConTeXt has preliminary epub http://en.wikipedia.org/wiki/EPUBsupport... Does ConTeXt refer to a suite of tools, or only the context command? Either way, it appears that the line between the command and the tool set is blurred a bit. This is completely understandable, too, as you wouldn't want to write, the ConTeXt suite of tools includes a command, mtxrun, that can produce EPUB files all the time when talking about EPUBs. supporting all variants of epub in the backend would be the same as hardcoding all kind of xml dts in the frontend (docbook, tei, whatever); instead we provide a general xml handler and a general xml export That paragraph would be an excellent addition to the wiki; not sure where though.

Does anybody already made a full validated epub ebook with ConTeXt

Is there more information about the current status of the export

You need \setupbackend[export=yes] in your document. When you put the setup above in a "epub" mode you create a epub-document only when you enable the mode which is recommended because it can have side effects for the normal PDF. To avoid these side effects make an extra ConTeXt run by enabling the mode to get the epub file.

Re: [NTG-context] EPUB woes
Hi All, I find that the ConTeXt approach to creating the EPub is flawed is a fundemental way! NOT TECHNICALLY. The EPub Standard is a big mess and if you really look at not a true standard in a true sense. Let me explain. 1) The file structure is well documented and properly defines the way a EPub file MUST contain and how file therein must be structure and listed. (notice that I use the word MUST) 2) Now, what a EPub-READER must implement to handle is very little. There are HARDLY ANY provisions that a certified EPuB-READER has to implement any particular engine or features therein to display/render the information contain in the EPub-file/wrapper. In other words it is simply a wrapper file format. and truly nothing more. There is NO REQUIREMENT in the standard that perfectly valid xhtml or HTML5 will be properly displayed in a certified EPub Reader! The standard has become more strict in recent years, yet still lacking. Am 16.11.2013 um 18:37 schrieb Aditya Mahajan adit...@umich.edu: [snip, snip] When you run `mtxrun --script epub --make test`, it just takes the files specificied in the files field, and zips them in as a epub file. Now, in principle, any epub reader should support the any XHTML file; in practice, they only support the default XHTML tags. The XML+CSS file that ConTeXt generates are not handled correctly by most (all?) EPUB readers. Here is where my critic of ConTeXt approach grabs. What good is if one produces a perfectly correct EPub, yet hardly any EPub reader can handle. I remember correctly, an EPub Reader need not implement the handling of xhtml inorder to be certified or, if you wish, adhere to the standard. The basic reason why xhtml is handled is because most html renders handle xhtml. Yet, the standard only requires that very basic html features be implemented and the author is required to offer fallbacks incase features are not supported. So there are three options: 1. Wait until the EPUB readers catch up. It took almost 10-15 years for the browsers to catch up with the HTML standards, and I don't have much hope for EPUB readers here. Last I checked, none of them supported even MATHML-2. Like I mentioned above a EPub reader is not REQUIRED to support it! 2. Write a script (either using xmlproc, or using you favorite XML parser in your favorite language) that converts the XML generated by ConTeXt into a standard XHTML file. This is the easiest and the least time consuming alternative. AGAIN, as mentioned above there is no guarantee that it will be displayed properly. Support/export of HTML5 would seem to me to be a better option, but then the HTML5 standard is not complete and not fully supported by most newer ereaders, also. 3. Modify the way in which ConTeXt generates the XML files. Ideally, I should be able to write something like Would be nice if there where commands in ConTeXt or a module for defining what should go into the CSS and a mode epub where the ConTeXt commands are converted to suitible HTML5 structures that are suitiable for most ereaders. Features: 1) margins in percentages 2) font sizes based on em 3) a new file for every chapter optional for sections user defined Just a few. Lots more can be found in any decent documentation on writing ebooks. regards Keith. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

For anything non-trivial (multiple types of floats, multiple types of emphasis, etc.) you have to resort to some sort of pre-processing of input. Pandoc is the only tool that does Markdown to ConTeXt conversion. There are more tools for Markdown to LaTeX conversion. The ConTeXt markup generated by pandoc is not ideal (\bf, \em, etc instead of semantic markup); it is possible to change the output, but you need to learn how to program in Haskell. You can start with ConTeXt and generate epub. However, ConTeXt generates XML+CSS rather than pure XHTML. Most browsers can handle XML+CSS, but most (all?) epub readers cannot. So, the output is not usable without some post-processing (this might have changed, I haven't tested ConTeXt epub in a year or so). In the long run, I think that the easiest way to generate multiple output formats for non-trivial input text is to use XML as your input format.

No. For a proper XML/XHTML export you need this markup. Also use \definehighlighting instead of switches like \em or \bf. In my experience, you can work with the exported raw XML if your markup is good, but you must convert it to usable HTML yourself.

Re: [NTG-context] ConTeXt epub workflow
Dear Idris If your document is simple I would consider the following workflow. I use this method for simple novels to produce both ePubs and Kindle output relatively quickly from a word docs which authors send me. Load the word doc into OpenOffice and save in OpenOffice format (.odt). Using the Writer2ePub extension in OpenOffice convert to ePub. You will get a reasonable looking ePub if you have taken a little care to style the document beforehand. Load the ePub into Sigil and tidy up the ePub. I Usually split the ePub into Chapters, embed fonts and add any images where I want them to go at this point. Once you are happy with the ePub you should test it on the various eReaders to make sure it looks as expected, don't be surprised to see differences and you may have to create different ePubs for the different eReaders. I have to do that for iBooks and Kobo eReaders. The idpf have an online ePub validator for ePubs which you should use to check for ePub standard compliance. Adobe Digital Editions is a useful tool here. You can now convert it into Kindle format using Kindle Previewer. If it requires changes, do that in Sigil and then run through Kindle Previewer again. To get pdf output I have been experimenting with pandoc quite recently with some success. I take the ePub and rename as a zip file and open it to expose its directory structure. Using pandoc I convert it to ConText code and tidy up a wee bit but, on the whole, Pandoc gives a not bad conversion even if images are present. Again you will probably have to tidy up the Context code and play about with fonts etc. This workflow looks a wee bit complicated but it does work well once you get the hang of it. I had originally tried using the Context to ePub but as previous correspondents have intimated you only get xml output rather than xhtml which is what eReaders require. If you need help feel free to email me privately.

Re: [NTG-context] EPUB XHTML Format
Hi, never mind not being able to add the books to online marketplaces (such as Amazon) because, again, the output does not validate. I think the simplest thing to do would be to update the wiki and have a note that informs readers that while ConTeXt can be used to generate an EPUB, it is likely that that EPUB will be unusable for devices without further transformation of the XML content. At least that way the knowledge is out there and people are forewarned that not all EPUB documents are equivalent.

On 2/17/2015 8:24 AM, Keith J. Schultz wrote: Hi Axel, All, You have mentioned that most current ebook readers can not display MathML. Well, the problem lies in the epub guidelines for the readers. The problem is even worse. many readers do not even implement the full HTML5 standard. though that is the standard used in the latest epub stadnard. The fact is to be considered epub readers the do not have to, it is a problem of the epub reader definition. The problem is what should ConTeXt output? Should it output code that implements according to the full epub standard OR JUST what is handled by most epub readers! IMHO : ConTeXt should not output XHMTL for epub, but HMTL5. Yes, yes, I know XHMTL is part of HMTL5. And html 5 is just html with some extras (and assuming javascript i guess) ... marketing. Another question for me is if ConTeXt should also output code for the iBooks epub format, (Basicaly epub, but some extras). Isn't a book supposed to be independent and kind of portable + long term visible? So no way that a context epub will be specific for a device. (I probably can't even get it on / test it on my outdated ipad 1 anyway.) There are thing you can do in/with ConTeXt that would work with iBooks that do not in „ordinary“ epub books. Then, there is the Kindle format one might want to consider! Another lock-in device. Another, question which needs investigation is if the ConTeXt output for epub, also, implementing the fallbacks for missing features which is required? Context outputs three varants: regular xml, xhtml, and stupified xhtml with div/class tagging. The last one is supposed to work on all devices as it doesn't demands anything beyond css. Just some added thoughts. Basically, you can only expect ConTeXts epub output to be a starting point that then has to be tweak. Indeed, as it's all xml one can process it into something 'better'. There is no way we can adapt to every change in specs, so the best we can do is something generic. Hans regards Keith.

Re: [NTG-context] Bugs in XML export (for ePub)
Hi Hraban, I tried to create ePubs using ConTeXt late last year (it was a driving factor for me to switch from LaTeX). In practice, ConTeXt cannot actually produce ePub content of any sufficient complexity that an ePub reader (such as Kindle) can read. I abandoned that development line a while ago. That said, ConTeXt is orders of magnitude easier to work with than LaTeX (for me) and has an architecture that holds a promising future. Since my project exports XML, I began an ePub solution using XSLT and DocBook. The ant4docbook Java application can produce ePub files from DocBook using an ant task, making the API simple to use. The resulting ePub archive can be read by various e-readers. http://ant4docbook.sourceforge.net/ Unless anyone says otherwise (or there have been momentous improvements in this area), I would recommend that you do not use ConTeXt to create ePub files. While technically it can produce an ePub archive, you will waste countless hours hitting wall after wall. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

The current bad documentation on the Wiki is by me. I produced two commercial ePubs with ConTeXt, but it’s really no fun, and I needed my own scripts that replace ConTeXt’s ePub script. I’m starting with the "raw" XML export and use XSL (Saxon) to transform it to HTML plus the ePub special ePub files. After all, a Python (or whatever) script would have been the better solution for this complex conversion. A CSS that works with most important readers needed also a lot of time. (But that’s a problem of ePub/Readers, not of ConTeXt, of course.) I can’t recommend ConTeXt as a source for ePub.

I've been using a workflow to generate epub + PDF for several books so far, and in my experience, using Markdown base files is very good: you can include images, links, etc., and then you can use pandoc ( http://johnmacfarlane.net/pandoc/) to generate both epub and context source, also you can customize the templates used by pandoc to generate the context source; that way you can handle the pdf layout; however, you must remember that epub can't handle mathml; you must include equations as images, if you have them, and you won't have any real presentational features: epub is as simple as it can be.

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?

[NTG-context] EPUB XHTML Format

It is my understanding that these XML elements, however, do not conform to the minimal content models associated with XHTML 1.1. What needs to happen to take a minimal ConTeXt file (such as the attached) to produce a minimum viable EPUB that: - Generates XHTML headers (including !DOCTYPE and html...) - Produces images as img tags, rather than float tags. - Uses typical XHTML tags for body elements (e.g., ol for ordered lists). Ideally, I would like to do something such as: - context t.tex - mtxrun --script epub --make t.specification to generate an EPUB that passes validation of epubcheckhttp://code.google.com/p/epubcheck/wiki/Library, with an output XHTML file that more closely matches the XHTML specification.

I would say too structured, since it makes you provide both a ToC manifest and a navigation manifest that necessarily must include almost identical information ;) Of course, depending on a simplified browser for your document viewing and having lots of secret failover modes to handle poorly formatted documents makes the structure less meaningful than it ought to be. You are free to break your document into as many HTML chunks as you wish, but you are limited to fairly prosaic HTML and CSS. I'm of the impression the HTML documents generally map onto chapters so as not to distress the hardware's memory constraints too much.

Re: [NTG-context] EPUB XHTML Format
Hi, handle XML+CSS well. However, most (all?) EPUB readers don't. So, the question is asking if instead ConTeXt could generate a XHTML Precisely. If you need both EPUB and PDF, start with a semantically rich XML vocabulary, e.g. DocBook. In this case you can relatively easy transfrom My database doesn't generate DocBook. It generates a custom XML document from which I generate a web page, and a LaTeX document (though soon to be ConTeXt!). There is no reason, technically, why I cannot convert the source XML to either DocBook or directly to EPUB. There are, however, problems doing that, which Aditya correctly surmises: - Automatic section numbering taking care of different conversions. - Automatic index generation and sorting - Inserting hyphenation points at the appropriate place in the generated output (so that the browser can effectively rely on TeX's hyphenation algorithm to do line-breaking). - Convert TeX math to MathML. The current ConTeXT XML source can translate a well formed ConTeXt document into a XML document with the above features. Those are exactly the issues that I would love to resolve using ConTeXt for generating an EPUB. (The MathML isn't as important to me, but I can see other people wanting such a feature.) What about accessibility? I expect that visually impaired people would depend on document structure rather than its visualisation. That is a good point. The current XML structure produced by ConTeXt (Hans correct me here if I'm mistaken) is not accessible, as it doesn't adhere to strict XHTML. I suspect that div tags would not be accessible -- the only way to provide true accessibility in EPUB format would be by using the strict XHTML tags. for instance, we have more levels than H1..H6, so how to do H7? if someone has to deal with that, he/she can as well transform all into H1 with some class which is a local solution then I realize there is not going to be a one-to-one map of all possible ConTeXt macros to XHTML. For someone who has 7 levels of nested sections they would either have to rewrite some Lua or perform some post-processing (e.g., with XSLT). I would posit that a document with 7 levels of nested sections is not going to be a common occurrence. When I talk about strict XHTML, I'm proposing that a _simple_ ConTeXt document (up to 6 header levels, numbered and unnumbered lists, images, text emphasis, etc.) should generate a simple, validating XHTML document. Trying to attain 100% coverage of ConTeXt transmogrification to XHTML is ridiculous when, I suspect, 80% coverage would meet most needs. :-) It is definitely possible to translate the ConTeXt EPUB output to XHTML. However, there are practical realities that hinder such an approach. Architecturally, if anyone is going to translate an XML document to EPUB format, it certainly won't be this way: *XML + XSLT - ConTeXT File - ConTeXt EPUB XML + XSLT - EPUB + CSS* It'll be this way, which is less time-consuming, less complex, and less susceptible to err: *XML + XSLT (or API) - EPUB + CSS* However, it does not, as we all know, produce as feature rich output as leveraging the ConTeXt abilities that Aditya mentioned, which was the point: *XML + XSLT - ConTeXT TeX - EPUB + CSS* Kindest regards. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

[NTG-context] Best strategy for ConTeXt to ePub update

What is current support of ePub, will it export pictures automatically? 2. Do I need to rewrite source code to use those verbose \startsXXX of every element (paragraph, item,...) or is there any simplier way how to handle sources as they are now?

Problem solved? ;-) ConTeXT TeX reading xml - export - optional transform - EPUB + CSS* you want 'direct epub html from context' (no xslt) but on the other hand use xslt to map onto context while context can do xml directly ... chicken egg Well, given that ConTeXt doesn't actually produce validating EPUB documents, I suspect not many people will actually use that feature. It's great in theory, but if it produces books that don't actually work on the Kindle or Kobo, then it's unusable in practice -- never mind not being able to add the books to online marketplaces (such as Amazon) because, again, the output does not validate.

Re: [NTG-context] EPUB workflow from ConTeXt source?
Have you considered authoring in something besides context? Say TEI XML or Docbook, or even markdown (if possible)? If markdown is suitable, then you can end up with both epub and context at the end. Or if using TEI or docbook, you can write a map file (something I have been trying to do) and typeset the xml file directly with context. I'm always happier knowing that I can get as many different output types from a single source as possible.

With MkIV you can get a xml version of document with \setupbackend[export=yes]. But that XML is not ePUB's XML, I assume. no, but one can of course convert one kind of xml into another for epub one has to provice css etc anyway (and epub is not much more than packaged html + css) This would also be useful to me. In my experience, the unpleasant part of generating ePub is making correctly formatted manifests and putting them in the right places inside the right kinds of zip files. If ConTeXt could do this for me, it would certainly make life easier. On the other hand, it may not be appropriate to bother because there are other tools that will convert HTML to ePub for you and make the manifests (Calibre, for example). I consider CSS intractable so that's not something I would worry about ConTeXt generating for me, if it were on the table. going the other way around, processing an epub file also demands some handywork as the source code is not by definition well structured ePub is definitely structured. I would say too structured, since it makes you provide both a ToC manifest and a navigation manifest that necessarily must include almost identical information ;) Of course, depending on a simplified browser for your document viewing and having lots of secret failover modes to handle poorly formatted documents makes the structure less meaningful than it ought to be. You are free to break your document into as many HTML chunks as you wish, but you are limited to fairly prosaic HTML and CSS. I'm of the impression the HTML documents generally map onto chapters so as not to distress the hardware's memory constraints too much. Overall, ePub and Kindle's format strike me as too much and too little respectively. I should be able to change the font and the formatting, but I definitely consider HTML + CSS is too much complexity. ?

ConTeXt’s ePub output is not usable without conversion (to XHTML). Its XML output is even corrupt if you try with a project structure. You have to mark every structure like \start/\stopparagraph - very tedious! Some other workflow is probably more efficient.

Re: [NTG-context] Epub format Was: Re: Context to epub: itemize
Hi Hans, I have been playing with the on using LaTeX and later LuaLaTeX for create epub or ebook. Though I have not got around to. The idea was to set enviorments, macros and commands that would depending on a switch that would output the need HTML and epub structure or call the normal *TeX ones.

Re: [NTG-context] What happened to the ePub script?

Hi,
with the latest betas, the ePub script doesn’t work anymore.
Regardless with which file I call it, I get only:
the whole generation of epub was cleanup up (already a while ago)
$ mtxrun --script mtx-epub --make solo

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[

\starttext

\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

Re: [NTG-context] Epub woes
Please try the following example:
-- start code --
\setupbackend[export=yes,xhtml=test_00.xhtml]
\mainlanguage[de]
\language[de]
\setupexport
[title={A nice book},
author={Andy Tom},
firstpage={huhn.jpg},
]
\starttext
Hello world!
\stoptext
-- end code --
The firstpage export value (huhn.jpg) is your cover image. Please put huhn.jpg
or something else in the same directory as your tex file. I named the tex=file
test_00.tex in my case.
After compiling with the latest context, you can run 'mtxrun --script epub
--make test_00.specification' to generate the epub file.
Please note two more things:
(1) The mtx-epub script was broken a couple of days ago. Well not actually
broken, but somehow an old version sneaked in. If the author names and such do
not get exported into the epub, this might as well be the case for you. The
latest one (ver: 2012.11.14 11:37 MKIV fmt: 2012.11.16) works fine again.
(2) Calibre and other readers as well as e.g. the ipad have some nasty caching
feature. In case you change little things and try to reload the same book in
your reader, it might still show the old one from the cache. I found, that
deleting the 'old' book first works most of the times.
I just started working on the epub output of my lecture notes again, since
there were no readers able to output math until 2 weeks ago.
If I find some time later, I will update the epub page in the wiki.
I hope that helps.

Cover is not generated

Sectioning doesn't happen.
Paragraphing doesn't happen.
The resultant epub file cannot even be opened with FBReader.
Importing the epub into Sigil shows one big blob of text, with only the
between word spacing that's present in the source file. The \quotation{}
markup did get turned into quotation marks, chapter numbers were generated
and the rest of the markup was stripped out.
Same behavior with both the TeXLive 2012 version of ConTeXt and a quite

Re: [NTG-context] EPUB XHTML Format
Hi.
of course we could alternatively export all as div class=tag-subtag-...
but i don't like that too much; html itself is not rich enough for our
purpose
What about giving developers the ability to change the destination element?
For example:
\setuplist[chapter][
xml={\starttag[h1]#1\stoptag}
]
Would produce, upon export:
h1Chapter/h1
Or (using export instead of xml; I don't care what it is named):
\setuplist[chapter][
export={\starttag[div]\startattribute[class]{chapter}#1\stopattribute\stoptag}}
]
Similarly, this would produce:
div class=chapterChapter/div
This would offer the flexibility of custom XML documents without affecting
the default behaviour.
* Generates XHTML headers (including !DOCTYPE and html...)
not needed as we're 'standalone'
Having the ability to produce the !DOCTYPE... and htmnl elements could
be as simple as:
\setupexport[
standalone=no,
]
* Produces images as img tags, rather than float tags.
the css can deal with them (info is written to files for that)
Yes, but they aren't standard. There is an ecosystem of tools (e.g.,
Calibre, normalizing CSS templates, etc.), not to mention a widespread
knowledge-base, that groks the minimal XHTML specification. Plus, using XML
tags that are not in the minimal XHTML spec. means more testing on more
devices to make sure that their XHTML parsers render correctly.
xhtml has no typical tags .. it's xml + css (or xslt) ... unfortunately
browsers have
That is, a Strictly Conforming XHTML Document, as per:
http://www.w3.org/TR/2000/REC-xhtml1-2126/#docconf
the export of context is in fact just xml, and by tagging it as xhtml we
can apply css to it; but if someone has a workflow for producing epub an
option if to postprocess that xml file into whatever epub one wants
I could transform the ConTeXt-generated XML into strictly conforming XHTML,
but it was a step I was hoping to avoid. Right now my process is:
1. Convert XML data to a ConTeXt .tex file.
2. Convert ConTeXt to either PDF or EPUB.
3. Stylize EPUB using CSS.
I want to use ConTeXt here (instead of going directly from XML data to
EPUB) because ConTeXt provides functionality such as multiple indexes,
table-of-contents, and bundling the .epub. Having an extra step to generate
strictly conforming XHTML is architecturally painful as it means
transforming the document three times (XML - ConTeXt, ConTeXt - XML, then
XML - XHTML).
Everytime we look into epub there's another issue ... it's not a standard
but reversed engineered application mess (happen soften with xml: turn some
application data structures into xml and call it a standard)
Some book vendors only accept validating EPUBs. ConTeXt is documented as
being able to generate EPUBs. The documentation should state the EPUBs do
not validate and do not generate strictly conforming XHTML.
I have spent the last three weeks converting documents from LaTeX to
ConTeXt because the documentation stated that ConTeXt can produce EPUBs.
While true, the documentation did not mention its shortcomings. Had I known
in advance, I probably would have gone straight to EPUB using Java or, with
a little revulsion, PHP classes. ;-) That said, I probably should have
tested this feature sooner. :-)
as i have no real use/demand for epub it's not something i look into on a
daily basis
How can I help resolve these issues?
Merely testing (which I am happy to do) isn't going to produce a strictly
conforming XHTML document.
Kindest regards.
