List ignored files for integration with other tools

[omasanori]

Something like git ls-files --ignored or hg status --ignored will be useful for tools with "ignore files ignored by VCS" option. For instance, REUSE tool, a license scanner, use the mentioned commands to exclude ignored files in Git or Mercurial working directories.

Since files that are not ignored are automatically added (unless we address #323), maybe the "is ignored" check in REUSE could be implemented as "not in jj files". Do you think that would work?

[omasanori]

Thanks! I will try. One more question: is there an equivalent command to hg root? jj workspace root seems a bit different concept.

[martinvonz]

That should be the same concept. I think they both print the path to the current workspace (or "share").

[omasanori]

I see. Thanks a lot!
