FAQs

I don't want to use Tab for committing Copilot's completion

It's likely that Copilot's completion appears along with Sublime Text's autocompletion and both of them use Tab for committing the completion. This may cause a nondeterministic result.

Thus, you may want to let only one of them (or none) use the Tab key. If you don't want LSP-copilot to use the Tab key for committing the completion. You can set LSP-copilot's commit_completion_on_tab setting to false and add a custom keybinding like below.

{
    "keys": ["YOUR_OWN_DEDICATE_KEYBINDING"],
    "command": "copilot_accept_completion",
    "context": [
        {
            "key": "copilot.is_on_completion"
        }
    ]
},

I see UNABLE_TO_GET_ISSUER_CERT_LOCALLY error

If working behind a VPN and/or Proxy, you may be required to add your CA file into the NODE environment. See below for LSP-copilots support for this.

In LSP-copilot's plugin settings, add the following env key:

{
  "env": {
      "NODE_EXTRA_CA_CERTS": "/path/to/certificate.crt",
  },
  // other custom settings...
}
