ispell-autobuildhash(8)

NAME

   ispell-autobuildhash - Autobuilding the ispell hash file for some dicts

SYNOPSIS

    ispell-autobuildhash [--force]

      Options:
       --debug      Show some extra ispell-autobuildhash information.
       --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

   ispell-autobuildhash is a script that will manage ispell hash files
   autobuild, intended to be called from the dictionaries-common tools.
   Depending on the ispell 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 ispell packages prepared
   to use it, it will do nothing for other ispell dict packages.

OPTIONS

    --debug      Show some extra ispell-autobuildhash information.
    --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
                 'ispell-autobuildhash' trigger, but run real
                 B<ispell-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, ispell-autobuildhash expects a $dict.compat file in
   /var/lib/ispell ($dict stands for the hash or affix file basename)
   containing ispell major or 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 ispell, script will check if version in $dict.compat is
   different from ispell.compat and rebuild if so, updating $dict.compat
   with the new value. The particular way things are done depends on
   whether your dict has a single source or a multiple source like ipolish
   has.

   The most common case is having a single source. In this case you must
   put the $dict.aff file at /usr/lib/ispell/$dict.aff as usual and the
   munched wordlist compressed with gzip at
   /usr/share/ispell/$dict.mwl.gz.

   This script supports the way ipolish allows selection of
   subdictionaries to be put in the hash file. It will detect the presence
   of  the main language .desc file and call update-ipolish-hash as
   appropriate.

   Although this script looks for the existence of a update-ispell-hash
   script with supposedly similar functionality to update-ipolish-hash,
   this latter does not really exists, although it might be added at some
   time to ispell or to the dictionaries-common system, if enough demand
   is found.

   If your package provides more than one ispell dictionary you will need
   to do the steps above for each dictionary.

   Dictionaries-common scripts will call internally this script and create
   a hash file at /var/lib/ispell/$dict.hash. You must set a symlink to
   that file from /usr/lib/ispell/$dict.hash.

   Ispell dictionary packages using this script must make sure that
   $dict.compat is reset on every new install/upgrade, so hash is rebuilt.
   They must also make sure that $dict.compat and
   /var/lib/ispell/$dict.hash are removed on package removal

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

   Note that you are no longer suggested to ship empty files at
   /var/lib/ispell/$dict.compat and /var/lib/ispell/$dict.hash to help
   with reset/removal of those files, but explicitly create/update them on
   install and explicitly remove them on removal.

   ispell maintainer should also call this script from package postinst.
   When comparing versions it will get the ispell version from file
   /usr/share/ispell/ispell.compat, or if it does not exists, from the
   upstream version as given in the first line of 'ispell -vv output.
