Versioning rules.
=================

We use **major.minor** schema.

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

Getting sources (VCS).
======================

To clone repository run::

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

To push to repository you must have write permission and do::

  $ hg push ssh://$USER@hg.code.sf.net/p/gadict/code

or::

  $ hg clone https://$USER@hg.code.sf.net/p/gadict/code

Browsing sources.
=================

  http://hg.code.sf.net/p/gadict/code
                hgweb interface for official repository.
  https://sourceforge.net/p/gadict/code/
                Sourceforge Allure interface for official repository.

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

                FieldWorks Language Explorer (or FLEx, for short) is designed

                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.

                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.

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``).
