+class Rc2Grd(interface.Tool): |
+ '''A tool for converting .rc files to .grd files. This tool is only for |
+converting the source (nontranslated) .rc file to a .grd file. For importing |
+existing translations, use the rc2xtb tool. |
+ |
+Usage: grit [global options] rc2grd [OPTIONS] RCFILE |
+ |
+The tool takes a single argument, which is the path to the .rc file to convert. |
+It outputs a .grd file with the same name in the same directory as the .rc file. |
+The .grd file may have one or more TODO comments for things that have to be |
+cleaned up manually. |
+ |
+OPTIONS may be any of the following: |
+ |
+ -e ENCODING Specify the ENCODING of the .rc file. Default is 'cp1252'. |
+ |
+ -h TYPE Specify the TYPE attribute for HTML structures. |
+ Default is 'tr_html'. |
+ |
+ -u ENCODING Specify the ENCODING of HTML files. Default is 'utf-8'. |
+ |
+ -n MATCH Specify the regular expression to match in comments that will |
+ indicate that the resource the comment belongs to is not |
+ translateable. Default is 'Not locali(s|z)able'. |
+ |
+ -r GRDFILE Specify that GRDFILE should be used as a "role model" for |
+ any placeholders that otherwise would have had TODO names. |
+ This attempts to find an identical message in the GRDFILE |
+ and uses that instead of the automatically placeholderized |
+ message. |
+ |
+ --pre CLASS Specify an optional, fully qualified classname, which |
+ has to be a subclass of grit.tool.PreProcessor, to |
+ run on the text of the RC file before conversion occurs. |
+ This can be used to support constructs in the RC files |
+ that GRIT cannot handle on its own. |
+ |
+ --post CLASS Specify an optional, fully qualified classname, which |
+ has to be a subclass of grit.tool.PostProcessor, to |
+ run on the text of the converted RC file. |
+ This can be used to alter the content of the RC file |
+ based on the conversion that occured. |
+ |
+For menus, dialogs and version info, the .grd file will refer to the original |
+.rc file. Once conversion is complete, you can strip the original .rc file |
+of its string table and all comments as these will be available in the .grd |
+file. |
+ |
+Note that this tool WILL NOT obey C preprocessor rules, so even if something |
+is #if 0-ed out it will still be included in the output of this tool |
+Therefore, if your .rc file contains sections like this, you should run the |
+C preprocessor on the .rc file or manually edit it before using this tool. |
