NAME

       aspell-autobuildhash - Autobuilding aspell hash files for some dicts

SYNOPSIS

        aspell-autobuildhash [--force]

          Options:
           --debug      Show extra info about aspell-autobuildhash internal
                        work. Will also enable aspell affix validation.
           --dry-run    Show what would be done, but do nothing real.
           --force      Rebuild the hash file for all dicts providing a
                        compat file skipping the test.
           --triggered  Tell the script that is run in the triggers stage.

DESCRIPTION

       aspell-autobuildhash is a script that will manage aspell hash files autobuild, intended to
       be called from the dictionaries-common tools.  Depending on the aspell compatibility level
       and on the compatibility level used for the hash file if present, will decide whether it
       must be rebuilt or not. This script will only work on aspell packages prepared to use it,
       it will do nothing for other aspell dict packages.

OPTIONS

        --debug      Show some extra information about aspell-autobuildhash
                     internal work. Will also enable aspell affix validation.
        --dry-run    Show what would be done, but do nothing real.
        --force      Rebuild the hash file for all dicts providing a compat
                     file regardless of the compatibility levels found.
        --triggered  Tell the script that is run in the triggers stage. When
                     run under dpkg control, do not try to set the
                     'aspell-autobuildhash' trigger, but run real
                     B<aspell-autobuildhash> code. When not run under dpkg
                     control, real code will always be run and '--triggered'
                     option has no real effect.

PACKAGE MAINTAINERS

       To use this system, aspell-autobuildhash expects a $lang.compat file in /var/lib/aspell
       ($lang stands for the lang basename with variant if any, e.g. $lang is something like gl-
       minimos or en)) containing aspell compatibility version for last successful build or "0"
       or en empty file if hash is to be rebuild, as is for dictionary installation and upgrades.

       When upgrading aspell, script will check if version in $lang.compat is different from
       aspell.compat and rebuild if so, updating $lang.compat with the new value.

       Wordlists should previously be compressed either with gzip (and their extensions set as
       .mwl.gz or .wl.gz) or preferably first with aspell prezip and then gzipped (with .cwl.gz
       extension).  This applies both for plain wordlists and munched wordlists (in the ispell
       way) if you use affix compression.

       If your package will provide a single hash, install prezipped+gzipped wordlist as
       /usr/share/aspell/$lang.cwl.gz or, if prezip is not used, as
       /usr/share/aspell/$lang.mwl.gz.

       If your package will provide more than one aspell hash for the same $lang, you will need
       to place each compressed wordlist as e.g.  /usr/share/aspell/$subdict.cwl.gz, and the
       common $lang.compat as above. Then create a /usr/share/aspell/$lang.contents file with the
       base names of the subdicts, one in a line. For English that will contain, amongst other
       possible lines

        en-common
        en-variant_0
        en-variant_1
        en-variant_2
        en_CA-w_accents-only

       No need to use this file if a single hash is being created.

       Dictionaries-common scripts will call internally this script and create a single hash file
       at /var/lib/ispell/$lang.rws, or hash files at /var/lib/ispell/$subdict.rws. You must set
       a symlink to that files from /usr/lib/aspell/$lang.rws or /usr/lib/aspell/$subdict.rws as
       appropriate.

       Aspell dictionary packages using this script must make sure that $lang.compat is reset on
       every new install/upgrade, so hash is rebuilt.  They must also make sure that $lang.compat
       and all of /var/lib/aspell/$lang.rws or /var/lib/aspell/$subdict.rws are removed on
       package removal.

       As of version 1.10, installdeb-aspell script will understand 'auto-compat' and
       'auto-contents' fields in $dict.info-aspell file to help with this by adding needed
       debhelper snippets.  Put in that entry the base name(s) of your compat and contents
       file(s) and carefully check resulting maintainer scripts after build.

       Note that you are no longer suggested to ship empty files at any of
       /var/lib/aspell/$lang.compat, /var/lib/aspell/$lang.rws or /var/lib/aspell/$subdict.rws,
       but explicitly create/update them on install and explicitly remove them on removal.

       aspell maintainer should also call this script from package postinst.  When comparing
       versions it will get the aspell version from file /usr/share/aspell/aspell.compat.
