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 instalation 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.
