maybe Kai can have a look at it: as these are dealt with in a different we

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.

But the output (shaping) is not what is expected as you have observed.
Notably:
1. When a pre-base matra follows the akhn ligatures are broken
2. pref, pstf and blwf ligatures are not formed
you need to identify the place in the code where that has to happen after
which i can have a look at it (with real minimal examples)
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:
\char0D26 \char0D4D \char0D26 \char0D47%% DA, VIRAMA, DA, E
needs to form ligature DDA,E
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.
