[Message part 1 (text/plain, inline)]
I am working on `tamil-phonetic.el`, a "Tamil Phonetic Input for
Emacs". See https://github.com/rnchzn/tamil-phonetic and
https://raw.githubusercontent.com/rnchzn/tamil-phonetic/main/tamil-phonetic.el.
I will be submitting this library for inclusion in NON GNU ELPA.
In preparation for that step, I desire fixes for three issues listed
below. Of these first two are bugs, and the last is an API
enhancement request.
1. The `indian-tml-base-table' has no entries for letters ௐ and ஶ.
The fix for this would be to do this:
(setcar (nthcdr (seq-position (nth 2 indian-itrans-v5-table-for-tamil) '("AUM" "OM")
(lambda (s1 s2)
(when (and (consp s1) (consp s2))
(string= (car s1) (car s2)))))
(nth 2 indian-tml-base-table))
?ௐ)
(setcar (nthcdr (seq-position (nth 1 indian-itrans-v5-table-for-tamil) "sh"
(lambda (s1 s2)
(when (and (stringp s1) (stringp s2))
(string= s1 s2))))
(nth 1 indian-tml-base-table))
?ஶ)
I have chosen entry for "sh" above because of the recommendations
in the following link https://github.com/avinash311/itrans and
https://docs.google.com/spreadsheets/d/14wZl8zCa4khZV3El2VGoqurKBLGx21mbS-yORi4w7Qo/edit#gid=0
See the attached screenshot for relevant portions.
2. M-x describe-input-method RET tamil-itrans RET doesn't show the
help table. i.e., instead of saying
> Uses keymap ‘quail-tamil-itrans-syllable-table’, which is not currently defined.
it should display the value of `quail-tamil-itrans-syllable-table'
inline.
The problem is the docstring uses "keymap" syntax, when in actual
fact, that variable in NOT a keymap but a text with some display
properties.
There are two more such variables that have the same issues as
above variable.
See the attached screenshot.
3. `indian-make-hash` ALWAYS installs translation for decimal digits
0-9. Tamil decimal digits are NOT used at all i.e., it is not even
taught in Schools in the state of TamilNadu, India. So, I wanted a
way NOT to insall the translation for digits. I suggest one of the
following:
- Change signature of `(indian-make-hash TABLE TRANS-TABLE)' to
`(indian-make-hash TABLE TRANS-TABLE &optional
DONT-INSTALL-NATIVE-DIGITS)' or some such thing.
`indian-make-hash' is used by many indic scripts, so I am not
sure if other indian language users would have a need for
inputting native decimal digits. I--as a representative of Tamil
speakers--can say that we don't need that ON by default.
- Or provide a new API which honors looks at digits row of
TRANS-TABLE and honor it. This way the caller has more
flexibility in installing mapping of his choice.
