Emacs Github Copilot

Emacs and Github Copilot

In order to setup my Emacs to use GitHub Copilot I got my inspiration from Robert Krahn blog post about Setting up Github Copilot in Emacs .

I have a few differences in my setup:

  • Robert Krahn:
    • Defaults load Copilot, except for a list of modes where it is not relevant
    • Use an utility function that loops through 3 activation state (off, manual and full)
    • Use M-C- combinations
  • I :
    • Launch Copilot with PHP and Typescript mode hook (only for those modes)
    • Use an utility derived from Robert Krahn's one, but looping only through 2 states: off and full
    • Use the "Windows" key, which is s-

Here you are

(add-to-list 'load-path "/home/mihamina/.emacs.d/copilot")
(require 'copilot)
(defun rktmb/copilot-complete-or-accept ()
  "Command that either triggers a completion or accepts one if one
   is available. Useful if you tend to hammer your keys like I do."
  (interactive)
  (if (copilot--overlay-visible)
      (progn
        (copilot-accept-completion)
        (open-line 1)
        (next-line))
    (copilot-complete)))
    

(defun rktmb/copilot-change-activation ()
  "Switch between two activation modes:
   - manual: you need to press a key (s) to trigger completions
   - off: copilot is completely disabled."
  (interactive)
  (if copilot-mode
   (progn
     (message "deactivating copilot")
     (global-copilot-mode -1))
   (progn
     (message "activating copilot mode")
     (global-copilot-mode))))

(define-key copilot-mode-map (kbd "s-")   #'copilot-next-completion)
(define-key copilot-mode-map (kbd "s-")  #'copilot-previous-completion)

(define-key global-map       (kbd "s-") #'rktmb/copilot-change-activation)

Undefined global vim

Defining vim as global outside of Neovim When developing plugins for Neovim, particularly in Lua, developers often encounter the "Undefined global vim" warning. This warning can be a nuisance and disrupt the development workflow. However, there is a straightforward solution to this problem by configuring the Lua Language Server Protocol (LSP) to recognize 'vim' as a global variable. Getting "Undefined global vim" warning when developing Neovim plugin While developing Neovim plugins using Lua, the Lua language server might not recognize the 'vim' namespace by default. This leads to warnings about 'vim' being an undefined global variable. These warnings are not just annoying but can also clutter the development environment with unnecessary alerts, potentially hiding other important warnings or errors. Defining vim as global in Lua LSP configuration to get rid of the warning To resolve the "Undefined global vi...

CopilotChat GlobFile Configuration

CopilotChat GlobFile Configuration Want to feed multiple files into GitHub Copilot Chat from Neovim without listing each one manually? Let's add a tiny feature that does exactly that: a file glob that includes full file contents . In this post, we'll walk through what CopilotChat.nvim offers out of the box, why the missing piece matters, and how to implement a custom #file_glob:<pattern> function to include the contents of all files matching a glob. Using Copilot Chat with Neovim CopilotChat.nvim brings GitHub Copilot's chat right into your editing flow. No context switching, no browser hopping — just type your prompt in a Neovim buffer and let the AI help you refactor code, write tests, or explain tricky functions. You can open the chat (for example) with a command like :CopilotChat , then provide extra context using built-in functions. That “extra context” is where the magic really happens. Built-in functio...

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo...
