(Question) Setting up custom commands?

[lukepighetti]

I want to setup custom commands to do Flutter development with helix. I'm guessing this will have to wait for #998 or #122, but I will describe the use case here for tracking.

• Adding flutter command line tool commands to command palette, keybindings etc.
• Run flutter devices, store a list of devices in editor state, then dispatch run commands on these devices
• After running flutter run, it allows pressing keys to dispatch subsequent commands to the device, would be nice to hook these into command pallet entries, or hooks like saving a file triggering hot reload

A few more ideas

• It would be nice if we could setup context menus like space and g menus for these tasks
• some way to indicate connection status and selected device (could be in context menus)
• a quick way to see long running debug output

For reference: here's a CoC plugin that achieves most of these items in vim https://github.com/iamcco/coc-flutter

The first item on the list should be possible to do already, but the other two seem to require scripting capabilities.

is there a way to actually add custom commands? i wasn't able to find anything in the documentation

If by context menus you mean the bottom-right popups which show available follow up keybindings, you can already make these. E.g, to add an item to the space menu:

[keys.normal]
space = { foo = "bar" }

You can also construct your own menus, I have this for example:

[keys.normal.A-t]
# opening test files
p = ':vs ~/dev/test/python.py'
h = ':vs ~/dev/test/html.html'
r = ':vs ~/dev/test/rust.rs'
m = ':vs ~/dev/test/markdown.md'

How to get selection in “bar” as the command parameter in example 1

[keys.normal]
space = { foo = "bar" }

Support for adding custom commands for command mode (I think that's what op wants) is possible even before having a plugin system for having shortcuts one doesn't want to add as keybinds. Later these could be enhanced for calling API or plugin functions. I have something like this in mind:

# config.toml
[commands]
"ToggleMyGreatPlugin" = "myPlugin.toggle()"

# maybe better in languages.toml
[commands.rust]
"Test" = ":sh cargo test"
"Lint" = ":sh cargo clippy"
[commands.go]
"Test" = ":sh go test"

I might prefer something closer to git aliases. E.g., you would do:

[aliases]
test = "sh cargo test --color=none"

Thes, you should be able to do :test, :test --workspace, etc.

Update: I guess this is now discussed in #4423
