Article about josh-filter

[alexpdp7]

At work, we have discovered josh. I think it's a fantastic tool. However, IMHO having to run a new service is some overhead that some teams might not be comfortable with. Also, I was a bit intimidated because I had not seen a lot of josh use in the wild.

However, a colleague pointed me to:

https://github.com/rust-lang/miri/blob/11da987f4c7aa7ec56287c98410d6f020488ba34/miri-script/src/commands.rs#L233

; some open source project that is using josh to synchronize repos, so I was a bit encouraged to proceed and try to use josh for our needs.

That project is also using josh without a "permanent" service, using a command-line flow. This encouraged me to research josh-filter. I managed to combine the Josh documentation and that example to make a proof of concept.

Today, I've published an article explaining all the pieces:

https://github.com/alexpdp7/alexpdp7/blob/master/programming/git/combining_repos_with_josh_filter.md

. I think the Josh documentation is enough to figure this out, but I thought a full example would help others do similar tasks with more confidence.

The article contains a full walkthrough that you can follow locally that shows how to incorporate a repo into a subpath of a larger repo, and push/pull changes between the two.

Issues/PRs are welcome- I'm also happy if anyone uses this for any purpose- I wouldn't mind making some changes to incorporate it into the Josh documentation or whatever.
