Extractor Command Line

--source, -s

solution-file or project-file or directory

--target, -t

target PO template file name (*.pot)

--unixstyle, -u

producing unix-style (forward slash '/') path separators in output .pot files even on Windows systems.

#: ..\Gettext\examples\Examples.HelloForms\Form1.cs:38
msgid "Text encoding"
msgstr ""

vs

#: ../Gettext/examples/Examples.HelloForms/Form1.cs:38
msgid "Text encoding"
msgstr ""

While tools like GetText.Net or PoEdit will work with both path separator styles, some other tools like GNU commandline tools (xgettext and thelike) will always expect unix-style path separators.
If such tools are used in the process, specify the -u option to enforce forward-slash path separators also when running on Windows systems, otherwise you can omit.

--order, -o

Sorts catalogue entries alphabetically by message id before export. This enables a stable order of entries in the catalogue template, which is important when comparing/editing templates such as in diff/merge scenarios. If not explicitly sorted, catalogue entries may have an arbitrary order on each export, caused by parallelization of the extractor.

--version
