Hatch build hook plugin for GNU gettext
Project description
Hatch Gettext
Package | |
Meta |
This provides a build hook plugin
for Hatch that compiles multi-lingual messages with GNU
gettext's tools msgfmt
. It can also (optionally) use intltool
to:
- translate .xml and .desktop files
- search for left out files
- regenerate the .pot template
- display a status report for all translations
Table of Contents
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. The mo file directory is set using locale-directory
, which is
required.
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.
Identifying left out files using intltool-update
With every source distribution (sdist) build, to search for left out files,
which should have been listed in POTFILES.in
or POTFILES.skip
, set
identify-left-out
to true (the default value is false):
[tool.hatch.build.hooks.gettext]
locale-directory = "src/myproject/locale"
identify-left-out = true
Regenerating the .pot template using intltool-update
To regenerate the .pot template with every sdist build, set
regenerate-template
to true (the default value is false):
[tool.hatch.build.hooks.gettext]
locale-directory = "src/myproject/locale"
regenerate-template = true
Displaying a status report using intltool-update
To display a status report for all translations, set show-report
to true
(the default value is false):
[tool.hatch.build.hooks.gettext]
locale-directory = "src/myproject/locale"
show-report = true
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 using keys, and arrays of source files as values. 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.
