DESCRIPTION

This manual page documents briefly the ocaml-gettext command.

--action extract

Files provided are considered to be OCaml source files and ocaml-gettext tries to extract translatable strings of it. The output of the command is a POT file. As a special case, if a file named POTFILES is in the list of the file provided, every line of it is considered as a file to be searched.

--action compile

Files provided are considered to be PO file. These files are compiled in binary MO files,

--action install

Files provided are considered to be MO files. They are installed in their respective directories considering language, textdomain and category,

--action uninstall

This is the symmetric command to install, but it uninstalls files provided for the considered language, textdomain and category,

--action merge

Merges a POT file with the provided PO file.

--extract-command cmd

Command to extract translatable strings from an OCaml source file. This command should output the same marshalled structure as ocaml-xgettext. The best to do is to use the same build version of ocaml-gettext.

--extract-default-option options

Default options used when extracting translatable strings. These options are camlp4 options and will be passed to ocaml-xgettext when processing files that don't already have specific camlp4 options.

--extract-filename-option filename options

Specific filename camlp4 options. It is used when extracting strings from the specified filename. It overrides default camlp4 options.

--extract-pot filename

POT file to write when extracting translatable strings.

--compile-output filename

MO file to write when compiling a PO file. If not provided, the output will be the name of the PO file with ".mo" extension.

--install-language language

Language to use when installing a MO file.

--install-category category

Category to use when installing a MO file.

--install-textdomain textdomain

Textdomain to use when installing a MO file.

--install-destdir dirname

Base directory to use when installing a MO file.

--uninstall-language language

Language to use when uninstalling a MO file.

--uninstall-category category

Category to use when uninstalling a MO file.

--uninstall-textdomain textdomain

Textdomain to use when uninstalling a MO file.

--uninstall-orgdir dirname

Base directory used when uninstalling a MO file.

--merge-pot filename

POT file to use as a master for merging PO file.

--merge-backup-extension extension

Backup extension to use when moving PO file which have been merged.

--version

Return version information on ocaml-gettext.

--short-version

Returns only the version of ocaml-gettext. The return is made to be easily parseable by configure script. The output of this command will always be the shortest version string, made of numeric characters (0-9) and ".". The version strings should be compared considering that a version A is greater than a version B if there is a number between two "." of A that is greater than B the corresponding number, beginning at the right of the string. For example: 0.14 is greater than 0.13.1.

-help, --help

Displays the help about the ocaml-gettext command.

OCAML-GETTEXT OPTIONS

This section describes briefly the common options provided by programs using ocaml-gettext library.

--gettext-failsafe ignore

Defines the behaviour of ocaml-gettext regarding any error that could be encountered during the processing of string translation. ignore is the default behaviour. The string returned is the original string untranslated. This behaviour is consistent and allows to have a usable output, even if it is not perfect.

--gettext-failsafe inform-stderr

Same behaviour as ignore, except that a message is printed on stderr,

--gettext-failsafe raise-exception

Stops the program by raising an exception when an error is encountered.

--gettext-disable

Disables any translation made by ocaml-gettext. All translations return the original string untranslated.

--gettext-domain-dir textdomain dir

Defines a dir to search for a specific domain. This could be useful if MO files are stored in a non standard directory.

--gettext-dir dir

Adds a directory to search for MO files.

--gettext-language language

Sets the language to use in ocaml-gettext library. The language should be POSIX compliant. The language should follow the following convention: lang[_territory][.charset][@modifier]. The lang and territory should be two letters ISO code. Charset should be a valid ISO character set (at least recognised by the underlying charset recoding routine). For example, valid languages are: fr_FR.ISO-8859-1@euro, de_DE.UTF-8.

--gettext-codeset codeset

Sets the codeset for output.

Users should be aware that these command line options, apply only for strings after the initialisation of the library. This means that if the options initially guessed by ocaml-gettext don't match the command line provided, there should be some untranslated string, because these strings are translated before parsing options. This is particularly true for the usage message itself (--help): even if the strings are translated, they are translated before setting the correct option.

Some options (--gettext-codeset for example) are overrided internally for particular use. It should be required to always translate strings to UTF-8 in graphical user interface (because GTK2 requires it).

NOTES

Options --uninstall-language, --uninstall-textdomain, --install-language and --install-textdomain could be guessed from the filename provided. You must be aware that these options can conflict with the fact that you provide several files to install. For example, if you provide a textdomain, you should either install several MO files which filenames only reflect the language or only one MO file if you also provide a language. For example, you can execute ocaml-gettext --install-textdomain mytextdomain fr.po de.po without problem, but you cannot execute ocaml-gettext --install-textdomain mytextdomain --install-language fr fr.po de.po . This restriction is due to the fact that you should not over specified file installation.

Rules for guessing the language/textdomain are: language[.textdomain].mo. For a full automated install without giving any hints, through command line options, you should name your file fr.mytextdomain.mo or de.mytextdomain.mo.
