Kind of touches on #356 by integrating the Starship prompt directly into the shell.
Not finished yet and has surfaced a potential bug in rustyline anyway. It depends on https://github.com/starship/starship/pull/509 being merged so the Starship prompt can be used as a library.
I could have tackled #356 completely and implemented a full custom prompt feature but I felt this was a simpler approach given that Starship is both written in Rust so shelling out isn't necessary and it already has a bunch of useful features built in.
However, I would understand if it would be preferable to just scrap integrating Starship directly and instead implement a custom prompt system which would facilitate simply shelling out to Starship.
This feature allows a user to set `ctrlc_exit` to `true` or `false` in their config to override how multiple CTRL-C invocations are handled. Without this change pressing CTRL-C multiple times will exit nu. With this change applied the user can configure the behavior to behave like other shells where multiple invocations will essentially clear the line.
This fixes#457.
with the `help` command to explore and list all commands available.
Enter will also try to see if the location to be entered is an existing
Nu command, if it is it will let you inspect the command under `help`.
This provides baseline needed so we can iterate on it.
The original intent of this patch was to remove more unwraps to reduce
panics. I then lost a ton of time to the fact that the playground isn't
in a temp directory (because of permissions issues on Windows).
This commit improves the test facilities to:
- use a tempdir for the playground
- change the playground API so you instantiate it with a block that
encloses the lifetime of the tempdir
- the block is called with a `dirs` argument that has `dirs.test()` and
other important directories that we were computing by hand all the time
- the block is also called with a `playground` argument that you can use
to construct files (it's the same `Playground` as before)
- change the nu! and nu_error! macros to produce output instead of
taking a variable binding
- change the nu! and nu_error! macros to do the cwd() transformation
internally
- change the nu! and nu_error! macros to take varargs at the end that
get interpolated into the running command
I didn't manage to finish porting all of the tests, so a bunch of tests
are currently commented out. That will need to change before we land
this patch.
