Hatch Gettext

Configuration

The build hook plugin name is gettext.

Calling the plugin

Modify pyproject.toml to include the plugin as a build dependency:

[build-system]
requires = ["hatchling", "hatch-gettext"]
build-backend = "hatchling.build"

Compiling messages with msgfmt

This plugin requires .mo files be created; it also requires that the directory storing them is within the project's base directory, and is not equal to the project's base directory or the directory in which po files are sourced.

For example, for a project named myproject, and a src layout src/myproject, an acceptable directory in which to store the LC_MESSAGES/myproject.mo files would be src/myproject/locale

[tool.hatch.build.hooks.gettext]
locale_directory = "src/myproject/locale"

Optionally, specify values for the gexttext output name and the source directory where po files are found:

[tool.hatch.build.hooks.gettext]
locale_directory = "src/myproject/locale"
i18n_name = "myproject" 
po_directory = "po-files"

If i18n_name is not specified, the name in [project] in the pyproject.toml is used. If po_directory is not specified, the directory po is used.

Translating files using intltool-merge

This plugin allows for but does not mandate translating .xml and .desktop files using intltool-merge. Using [tool.hatch.build.hooks.gettext.files], specify the destination directories for the translated files on the left, and arrays of source files on the right. For example:

[tool.hatch.build.hooks.gettext.files]
"share/applications" = ["data/net.myproject.desktop.in"]
"share/solid/actions" = ["data/kde/net.myproject.desktop.in"]
"share/metainfo" = ["data/net.myproject.metainfo.xml.in"]

Cleaning output files

The plugin includes logic to remove the files it outputs using hatch's clean hook. As well as individual files, any output directories created will also be removed, as long as these directories do not contain files created by something other than this plugin.
