Versioning rules
================

We use **major.minor** schema.

Until we reach 5000 words **major** is 0. **minor** updated from time to time.

Getting sources
===============

Cloning repository::

  $ hg clone http://hg.defun.work/gadict gadict
  $ hg clone http://hg.code.sf.net/p/gadict/code gadict-hg

Pushing changes::

  $ hg push ssh://$USER@hg.defun.work/gadict
  $ hg push ssh://$USER@hg.code.sf.net/p/gadict/code
  $ hg push https://$USER:$PASS@hg.code.sf.net/p/gadict/code

Browsing sources online
=======================

  http://hg.defun.work/gadict
    hgweb at home page.
  http://hg.code.sf.net/p/gadict/code
    hgweb at old home page (but supported as mirror).
  https://sourceforge.net/p/gadict/code/
    Sourceforge Allure interface (not primary, a mirror).

Dictionary source file format
=============================

For source file format used dictd C5 file format. See::

  $ man 1 dictfmt

Shortly:

 * Headwords was preceded by 5 or more underscore characters ``_`` and a blank
   line.
 * All text until the next headword is considered the definition.
 * Any leading ``@`` characters are stripped out, but the file is otherwise
   unchanged.

For convenience also used such assumptions:

 * Headwords was separated by ``;<SPACE>`` (and all was placed on single line).
 * UTF-8 encoding was used.
 * Lines started with ``#`` striped out (comment syntax).
 * First line with ``ABOUT:`` used as description of dictionary.
 * First URL (line with ``http://``) used as dictionary home page.

Comment syntax convention
=========================

As 'dictd -c5' format does not support comment syntax we filter out all
lines that start with '#'.

TODO convention
===============

Entries or parts of text that was not completed marked by keywords:

  TODO
    incomplete
  XXX
    urgent incomplete

Makefile rules ``todo`` find this occurrence in sources::

  $ make todo

Dictionary file name convention
===============================

BNF form::

  FILE ::= "gadict_" NAME ".gadict"

``NAME`` may have form ``ISOCODE "-" ISOCODE``, like ``en-ru``, where
``ISOCODE`` is ISO 639-1 language (2 letter) code

``NAME`` may be a dictionary abbreviation name.

During dictionaries compilation and releases ``".gadict"`` suffix changed to
appropriated but base name should be preserved as ``"gadict_" NAME``.

World wide dictionary formats and standards

  http://www.sil.org/computing/shoebox/mdf.html
                Multi-Dictionary Formatter (MDF). It defines about 100 data
                field markers.

                FieldWorks Language Explorer (or FLEx, for short) is designed
                to help field linguists perform many common language
                documentation and analysis tasks.
  http://code.google.com/p/lift-standard/
                LIFT (Lexicon Interchange FormaT) is an XML format for storing
                lexical information, as used in the creation of dictionaries.
                It's not necessarily the format for your lexicon.
  http://www.lexiquepro.com/
                Lexique Pro is an interactive lexicon viewer and editor, with
                hyperlinks between entries, category views, dictionary
                reversal, search, and export tools. It's designed to display
                your data in a user-friendly format so you can distribute it
                to others.

Register gadict dictionaries for dictd under Debian
===================================================
::

  $ su
  $ cat >>etc/dictd/dictd.order <<EOF
  gadict-dictabbr
  /home/user/usr/share/dictd/
  $ dictdconfig --write
  $ /etc/init.d/dictd restart
  $ ^D
  $ dictdconfig --list
  $ dict -d gadict-dictabbr v

Typing IPA chars in Emacs
=========================

For entering IPA chars use IPA input method. To enable it type::

  C-u C-\ ipa <enter>

All chars from alphabet typed as usual. To type special IPA chars use next key
bindings (or read help in Emacs by ``M-x describe-input-method`` or ``C-h I``).

For vowel::

  æ  ae
  ɑ  o| or A
  ɒ  |o  or /A
  ʊ  U
  ɛ  /3 or E
  ɔ  /c
  ə  /e
  ʌ  /v
  ɪ  I

For consonant::

  θ  th
  ð  dh
  ʃ  sh
  ʧ  tsh
  ʒ  zh or 3
  ŋ  ng
  ɡ  g
  ɹ  /r

Special chars::

  ː  : (semicolon)
  ˈ  ' (quote)
  ˌ  ` (back quote)

Alternatively use ``ipa-x-sampa`` or ``ipa-kirshenbaum`` input method (for help
type: ``C-h I ipa-x-sampa RET`` or ``C-h I ipa-kirshenbaum RET``).
