AutoHotkey syntax or auto-completion

[Lateralus138]

I am curious if there were any plans to implement AutoHotkey Syntax and/or auto-completion? I know it's not the most popular language, but I write a considerable amount of it and I am starting to like Helix. There's already syntax and auto completers in other editors/IDE so I know there's potential for one here, just not sure if anyone has it planned.

Sorry if this is the wrong section to put this in, I almost put it in ideas, but wasn't sure.

Hi, sorry for the inconvenience.
But, since you're an autohotkey expert, would you please help in implementing a dual key role for capslock.
I need it when pressed to be ctrl and when tapped to be esc.
But, I need to work with other remaps. For example, I remaped alt-j as down arrow, I need when using caps dual role to be able to send ctrl-down when holding ctrl-alt-j.
Thanks in advance, and I apologize for the inconvenience.

I need it when pressed to be ctrl and when tapped to be esc.

Do you mean held for an extended period of time versus pushed?

Or do you mean when the state is toggled?

If so then this should be the AutoHotkey part (adjust timing as needed):

*CapsLock::
{
  Send "{LControl down}"
}

*CapsLock up::
{
  Send "{LControl Up}"
  if (A_PriorKey == "CapsLock")
  {
    if (A_TimeSincePriorHotkey < 1000)
    {
      Suspend "1"
      Send "{Esc}"
      Suspend "0"
    }
  }
}

Thank you so much.

I think there may already be support, just with some effort; helix works with LSPs to support languages. It looks like there's a few AHK LSPs on github, but personally haven't tried any.

Thanks, I did do a quick web search before I asked this and all I could find was an LSP for using OpenAI/CoPilot for auto-completions and I don't care to use AI much. I will check it out anyway just to see what it's about. I will search here specifically at GH for some, but they didn't come up in my initial search. Thanks again!

So I read that the AutoHotkey LSP plugin for VS Code should work (which I already had installed), but I I can't seem to get it working. I also tried installing the plugin using the plugins repository node installation instructions, but with the same results. I am very new to Helix and have been reading through the documentation for installing a new language, but I don't think I've done it right. Would anyone mind helping?

Here's my config in languages.toml:

[[language]]
name = "autohotkey"
file-types = ["ahk"]
scope = "source.autohotkey"
indent = { tab-width = 2, unit = " " }
comment-tokens = ";"
formatter = { command = "node", args = ["</MY/USER/PATH>/.vscode-oss/extensions/mark-wiemer.vscode-autohotkey-plus-plus-6.5.0-universal/ahk2/server/dist/server.js", "--node-ipc"] }
language-servers = [ { name = 'vscode-autohotkey2-lsp' } ]

I tried changing name in language-servers to the server.js path with no different result.

Results of the health check:

PS> hx --health autohotkey
Configured language servers: None
Configured debug adapter: None
Configured formatter: node
Binary for formatter: C:\Program Files\nodejs\node.exe
Tree-sitter parser: None
Highlight queries: ✘
Textobject queries: ✘
Indent queries: ✘

Result:

first you need to download the lsp, follow the instructions from the readme https://github.com/thqby/vscode-autohotkey2-lsp?tab=readme-ov-file#use-in-other-editors,

assuming you created a ~/src folder and installed the lsp in that folder, this is what the lsp config will look like

[[language]]
name = "autohotkey"
scope = "source.ahk"
file-types = ["ahk"]
comment-token = ";"
indent = { tab-width = 2, unit = " " }
language-servers = ["ahk2"]


[language-server.ahk2]
command = "node"
args = ["c:/Users/your_username/src/vscode-autohotkey2-lsp/server/dist/server.js", "--stdio"]

the lsp includes a formatter so you don't need to configure one, it also includes some syntax highlighting with semantic tokens but helix only highlights using treesitter so you won't have highlighting, and i don't know if there's treesitter highlighting for ahk2

note: the lsp needs to detect ahk v2 or it exists so make sure to have #Requires AutoHotkey v2.0

[Lateralus138]

This did it, thanks! Yeah, there's no syntax highlighting at all, but auto-completion and info work. I'll look into a treesitter for it, but no highlighting is a no go for me for now. Thanks a lot!

[sibouras]

nice, ye same for syntax highlighting, can't code without it, hopefully someone writes treesitter queries for it someday

[IllyStable]

Not completely sure on this, but I think you have to define the ahk lsp in the [[language-server]] section too

Thanks to @sibouras and @IllyStable for the help!
