Creates an empty POT from Tidy's native English header, or optionally from

a specified language using English as a backup source. POT files have no

translated strings; they are empty templates.

Use case: in the Tidy localization process there's probably no real reason

to use this unless you prefer to set the header manually compared to how

#{File.basename($0)} msginit does it.

|
|
Converts an existing Tidy header H file to a PO file using the locale
|
|
specified in the H file. Specifying <input_file.h> is required, and
|
|
multiple input files may be specified.
|
|
|
|
The resulting file will consist of English original strings, the
|
|
translated strings from the header, and blank translated strings if not
|
|
specified in the header.
|
|
|
|
You can use the --baselang option to gather the untranslated strings from
|
|
a different header file. This may be useful for translators that want to
|
|
implement a region-specific localization, for example, translating `es`
|
|
to `es_mx`.
|
|
|
|
Use case: create a PO file from an existing Tidy header H file using a
|
|
combination of languages that are suitable to you.

|
|
Creates a Tidy header H file from the specified <input_file.po> PO file,
|
|
which is a required argument. Multiple input files may be specified.
|
|
|
|
You can use the --baselang option to exclude already translated strings from an
|
|
inherited base language. This will help keep Tidy's library and executable size
|
|
to a minimum. For example if you wish to generate a header for es_mx (which uses
|
|
es as its base language), then you should specify the "--baselang es" option.
|
|
This will ensure that the generated header includes only strings that are unique
|
|
to es_mx.
|
|
|
|
Use case: Tidy can only build H files, and so this command will convert
|
|
PO files to something useful.
