Extract strings from source code with xgettext

[armijnhemel]

Some notes for extracting strings from source code files with xgettext.

I have found the following commandline options to work well for me:

xgettext -a -o - --no-wrap --no-location --omit-header -

This reads the data from standard input, and outputs results on standard output. The standard gettext header is not included (which makes parsing a little bit easier) and file name data is also not included (the "location"), as I am assuming I already know which file I am reading plus I am not interested in the location(s) of the strings in the file (but maybe this is something you want). This also makes parsing things a little bit easier. The --no-wrap parameter is for putting results on a single line, which also makes processing results easier.

Some options that are worth looking at: -L as xgettext tends to only look at file extensions.

Closing #5 as dupe of this

This is now completed with PR #7
To test this feature:

• pip install source-inspector
• scancode --source-string --yaml -

You will see the "source_strings" data attached to a each source file entry
