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 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.
