Where to find information to update /helix/language.toml

[lauccode]

I was looking to use helix for cpp with vscode-cpptools.
But I can not find the way to update the /helix/language.toml.
I tested it with lunarvim. And it is ok.

I guess it could work with helix now just be updating the .toml.
Should be nice to know how to update .toml easily ?

I can see the rust example in helix documentation.
But I don't know how to set exactly the good value to set cpp debugger with vscode-cpptools ?

The languages.toml file is here: https://github.com/helix-editor/helix/blob/master/languages.toml but you can also have one in your ~/.config/helix/languages.toml which overrides keys from the one in this repository. For example if I wanted to disable auto-format in rust, I could use:

# ~/.config/helix/languages.toml
[[language]]
name = "rust"
auto-format = false

The current configuration for CPP files is here:

helix/languages.toml

Lines 189 to 220 in e8f0886

	[[language]]
	name = "cpp"
	scope = "source.cpp"
	injection-regex = "cpp"
	file-types = ["cc", "hh", "cpp", "hpp", "h", "ipp", "tpp", "cxx", "hxx", "ixx", "txx", "ino"]
	roots = []
	comment-token = "//"
	language-server = { command = "clangd" }
	indent = { tab-width = 2, unit = " " }
	[language.debugger]
	name = "lldb-vscode"
	transport = "stdio"
	command = "lldb-vscode"
	[[language.debugger.templates]]
	name = "binary"
	request = "launch"
	completion = [ { name = "binary", completion = "filename" } ]
	args = { console = "internalConsole", program = "{0}" }
	[[language.debugger.templates]]
	name = "attach"
	request = "attach"
	completion = [ "pid" ]
	args = { console = "internalConsole", pid = "{0}" }
	[[language.debugger.templates]]
	name = "gdbserver attach"
	request = "attach"
	completion = [ { name = "lldb connect url", default = "connect://localhost:3333" }, { name = "file", completion = "filename" }, "pid" ]
	args = { console = "internalConsole", attachCommands = [ "platform select remote-gdb-server", "platform connect {0}", "file {1}", "attach {2}" ] }

. Also see https://docs.helix-editor.com/languages.html but currently DAP related configuration and DAP usage are experimental and undocumented.

Hello, thanks a lot for all information.
I guess it means that I need to wait documented usage before to try to use vscode-cpptools ?

I'm looking to open automatically files when I open helix rather than open it one by one each time.
This is the main point I don't start to use helix now.
Some features are missing. But it seems to be enough to start to edit at least.

I found a workaround to manage project with git(with help of lazygit) to be able to open multiple files of a commit with Helix :
