Hans, it would be great to see Indic languages support in context/mkiv. At the moment I am typesetting, for example, in Malayalam using mkii+xetex. So I tested context (from TeXLive 2013 distribution) but found that the rendering is not correct. There are examples and screenshots here in an old thread: http://tex.stackexchange.com/questions/89118/context-xetex-texlive-2012-does-not-work-for-indic-scripts-like-malayalam I am interested in helping, at least by testing, especially Malayalam support. Harfbuzz has excellent opentype support for Malayalam now, which could be used for comparing the rendering. -- Cheers, Rajeesh http://rajeeshknambiar.wordpress.com ___ 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 ___

As far as I understand, 'rphf' and 'half' forms are essential for
Devanagari, so skipping them completely might not be a good idea...

[NTG-context] ConTeXt hyphenation patterns for Indic languages
Hello, I have tried to generate the hyphenation patterns for Malayalam language from the TeX hyphenation patterns, but the unicode characters were skipped. On TeXLive 2013, ConTeXt version 2013.04.20, this is what was tried: 1. Uncommented line for "ml" in mtx-patterns.lua 2. Ran "mtxrun --script patterns --convert --path=/usr/share/texlive/texmf-dist/tex/generic/hyph-utf8/patterns/txt/ --destination=/usr/share/texlive/texmf-dist/tex/context/patterns/" 3. Output shows all patterns are removed with similar messages to: "mtx-patterns| removing line with suspected utf character അ (0x0D05), category lo: 1അ1" What is the proper way to add hyphenation patterns for a new language? In addition, how to add a 'new language' to the ConTeXt base (such that \language[ml] can be used? I see "base/lang-ind.mkii" where I could add "\setupheadtext" etc for the language, what is the equivalent for mkiv?

[NTG-context] Malayalam shaping with mkiv/LuaTeX
Hello, especially Hans and Kai,
I have succeeded to an extent in adding Malayalam shaping to the
existing Devanagari shaping. Being a complete novice in Lua and mkiv,
I'm at a point where your expertise is needed to proceed further.
Please find the attached patch, test case listed below and expected
rendering for comparison. Additionally needed to support:
1. Decomposing 2 part Matras (dependent vowels) - 0D4A, 0D4B, 0D4C
for Malayalam [Test cases 2 & 4]. This is needed (at least) for Tamil
also. I guess it is as simple as replacing one code point with 2
others - example: replace 0D4A with 0D46, 0D3E. See page 3 of this
Unicode standard: http://www.unicode.org/charts/PDF/U0D00.pdf
2. Handling "pref" opentype feature for v2 opentype spec (script tag
"mlm2"). This is required for Malayalam Ra ligature, the glyph is
formed correctly but it needs to be reordered as pre-base to the base
syllable [Test case 1]. (Note that the old spec "mlym" handles "Ra
form" as "pstf" and no reordering required). You can observe the
difference in Test case 5 - Ra form should be attached to first
consonant instead of second one ("mlm2" needs glyph formed by
Virama+Ra to be reordered as pre-base to first consonant, while "mlym"
doesn't need to).
3. Handling "pstf" opentype feature. It works mostly [Test case 8],
except when a post-base Matra follows [Test case 9].
4. Test cases 6 & 7 shows an example where glyph formation fails when
a "pstf" Ya follows. This works correctly with some other conjuncts,
though.
4. font-odv.lua hard coded Devanagari Virama (094D) and Ra (0930) in
certain places, which needs to use table values to handle other
scripts.
5. I had to change "methods.deva" to "methods.mlym" and "methods.dev2"
to "methods.mlm2" to get this working, not sure how best to handle
multiple scripts.
6. There are other cases like Dot-reph (0D4E) which uses GPOS table
and requires reordering as post-base to the syllable follows it, but I
haven't looked into them yet.
i) The font used is Rachana, which supports both "mlm2" and "mlym"
specs, can be downloaded from here:
http://download.savannah.gnu.org/releases/smc/fonts/malayalam-fonts-6.0/Rachana/Rachana.ttf
You can switch to "mlm2" and "mlym" in test case.

With the initial patch I had sent, these were working okay (ie, akhn,
pref, pstf and blwf ligatures were being formed).
Minimal character sequence for test case:
\char"0D26 \char"0D4D \char"0D26 \char"0D47%%
needs to form
With initial patch, in "methods.dev2", (syllablestart,syllableend)
were: (0D26, 0D26) {cluster DA, VIRAMA, DA} and (0D47,0D47) {E}.
Current beta gets (0D26,0D4D) {cluster DA, VIRAMA} and (0D26,0D47)
{DA, E}. Something changed in "analyze_next_chars_two", may be?
Okay - found that you had not considered 0D4D (virama/halant) not as
"halant{}" but as "stress_tone_mark{}". Adding 0D4D to the array
"halant{}" restores the previous behaviour - ligatures are formed but
with issues mentioned in the initial mail. "analyze_next_chars_two"
indeed looks for halant.
