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

 ispell-autobuildhash [--force]

   Options:
    --debug      Show some extra information.
    --force      Rebuild the hash file for all dicts providing a 
                 compat file skipping the test.

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.

--debug Show some extra information. --force Rebuild the hash file for all dicts providing a compat file regardless of the compatibility levels found.

To use this system, just provide a $dict.compat file in /var/lib/ispell ($dict stands or the hash or affix file basename). Put a 0 in it or just create an empty one with touch. The 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 $dict.aff file at /usr/lib/$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. You are also suggested to create an empty file at /var/lib/ispell/$dict.hash in the install target of your package build process. This empty file will be overwritten when the real hash is created, but will make the hash be removed at package removal without any magic being done in the postrm and will also help to keep track about which package owns that file.

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.
