lsp-gst

The latest in a long series of profoundly useless projects from yours truly.

Supported Operations

• initialize
• shutdown
• textDocument/didOpen
• Multi-workspace support

Dependencies

lsp-gst depends on the following packages:

• An included version of gst-json, modified to use String rather than UnicodeString
• I18N
• STInST

And provides the following namespaces:

• LSP.GST - The primary namespace for GST-related LSP functions

Building & Installation

Build

First, ensure you have I18N and STInSt available (STInST is often left out of distributions' GNU Smalltalk packages). Then, run the following commands to generate and run a fresh lsp-gst image:

$ gst-package -t . package.xml
$ gst-load -iI lsp-gst.im lsp-gst

The language server protocol is now listening on stdin.

Use

Assuming you are using Emacs' lsp-mode, with smalltalk-mode from the official gnu-smalltalk repo. lsp-gst currently operates on stdio, but should be trivially modifiable to run on a proper socket in the future. A reasonable smalltalk setup for Emacs would be:

(load-file "path/to/smalltalk-mode.el")
(add-to-list 'auto-mode-alist '("\\.st" . smalltalk-mode))

(require 'lsp)
(lsp-register-client
 (make-lsp-client :new-connection (lsp-stdio-connection '("gst-load" "-iI" "path/to/lsp-gst.im" "lsp-gst"))
                  :major-modes '(smalltalk-mode)
                  :priority -1
                  :server-id 'gst-ls))

(with-eval-after-load 'smalltalk-mode
  (add-hook 'smalltalk-mode-hook #'lsp))

gst-lsp should activate and connect when you open a Smalltalk file.
