cli: add callJson ipc subcommand

[jmoggr]

The arguments parser for the ipc call subcommand allow_extra_args does not gracefully handle many JSON strings. It will allow '{"hello": "world"}', but it will strip out square brackets and split the JSON string on commas, among other issues.

This is worked around by adding a new callJson ipc subcommand which accepts one string argument which is passed directly to the ipc call.

I understand that this is kind of hacky, and am open to modify this or taking a different approach. I do think something should be done for JSON because it can be somewhat frustrating to debug/learn when simple cases work but complex cases fail. At the very least I could ditch this change and update the documentation for arguments.

This doesn't do anything differently than a normal call, which already don't strip out square brackets or split on commas.

which already don't strip out square brackets or split on commas.

That is not the behavior I am experiencing

splitting on commas:
 qs ipc call jsonTarget sendJson '[{"a": 1},{"b":2}]'
Too many arguments provided (1 required but 2 were provided.)
Function definition: function sendJson(jsonString: string): void

stripping brackets:
 qs ipc call jsonTarget sendJson '[]'
Too few arguments provided (1 required but 0 were provided.)
Function definition: function sendJson(jsonString: string): void

code:

import Quickshell import Quickshell.Io ShellRoot { IpcHandler { target: "jsonTarget" function sendJson(jsonString: string): void { console.log(jsonString); } } }

Looked into it. Appears to be a misfeature in the argument parser we use when parsing lists, which can't be disabled. Note that it will only trigger when the first character is '[' and the last character is ']'. I recommend wrapping it in an object for now to avoid those characters.

As it stands I don't want to merge this because it should just work without another subcommand.
