cl-i18n

http://quickdocs.org/badge/cl-i18n.svg

Prerequisites:

• ASDF
• uiop (if your ASDF version is < 3)
• cl-ppcre
• alexandria
• babel

Installation:

The best way to get cl-i18n working is using the excellent quicklisp

(ql:quickload "cl-i18n")

Usage

This library can load translations from file formats of the following types:
• GNU gettext text file (AKA PO files);
• GNU gettext binary file (AKA MO files);
• its native file formats (essentially a Common lisp S-exp).

Check the examples/ directory for an usage example.

Extracting translatable strings:

(cl-i18n-utils:gen-translation-file "/src/" "klingon.lisp"
                                    :ext "lisp$"
                                    :prefix-re "#!\"")

Will extract all #! strings¹ from all the files in directory "/src/" which name ends in "lisp" and set up a basic translation resource in klingon.lisp (Note: the output file if exists will be overwritten).

To make it work with CL-WHO, use the “str” directive, as in

    (with-html-output *out*
      (:p (str #!"Peace and love!")))

Please note that the library can accept gettext MO or PO files so nothing prevents you using GNU xgettext to extracts strings that needs to be translated and use its output as translation file.

Locating GNU message catalog files

According to GNU gettext manual the path to the catalog is system dipendent, the function search-mo-repository will try to figure out where that catalog could be; but its implementation is slow, memory consuming and sometimes fails (i.e. crash).

Simple example

Here is a way similar to GNU gettext style API; please note we are assuming "/usr/share/locale/" as the path where the catalog can be found and foo.mo is there...

We also let the library guess the right locale with find-locale.

(let ((*translation-file-root* "/usr/share/locale/"))
   (load-language "foo" :locale (find-locale))
   (format t "~a~%"  #!"Browse")
   (format t "~a~%" #!"Save as..."))

Old version incompatibility

This version deeply changed the file format of the translation table, however you can convert from the old format to the new one with:

(cl-i18n-utils:convert-save-dictionary oldfile-path new-filepath)

Note: the output file if exists will be overwritten

Bugs and issues

Please file bug report on the issue tracker.

Known issues

• Documentation is missing;
• Source code is mostly undocumented;
• PO file parser is slow.
