Subject: Make pinyin to Chinese character mapping available to elisp
X-Git-Tag: emacs-27.0.90~3548
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=28f7e981c10cddd06b879a79ade214f273ba4498;p=emacs.git

Make pinyin to Chinese character mapping available to elisp

* leim/Makefile.in: Build the file pinyin.el from pinyin.map.
* lisp/international/titdic-cnv.el (pinyin-convert): New function that
  writes the library pinyin.el, containing a new constant
  `pinyin-character-map'.
* .gitignore: Ignore the generated pinyin.el file.
