Elisp Language Server
This software is intended for use with editors other than Emacs. If you're already an Emacs user, we recommend using Emacs directly.
Here is the list of currently supported editors:
This software is intended to support editors beyond Emacs, targeting users who wish to work with Emacs Lisp in a more performant and responsive environment. Due to its single-threaded architecture, Emacs can become unresponsive when executing computationally intensive tasks.
A strong reference implementation is Emacs Elsa, which utilizes the Language Server Protocol (LSP) to delegate static analysis and other heavy operations to a separate Emacs process. This decoupling not only improves responsiveness in the primary editor but also enables parallelism, making large-scale analysis more practical.
Before installation, make sure you have all the following software installed!
Important
Ellsp can only be used with projects that utilize Eask as their package manager. Ensure your project is properly set up with Eask before using Ellsp.
Add these lines to your Eask-file:
(source 'gnu)
(source 'melpa)
(source 'jcs-elpa)
(development
(depends-on "ellsp"))Then install the language server:
# Install ellsp package.
eask install-deps --dev
# Install the proxy server.
eask exec install-ellspTo test to see if the server installed successfully, execute the following command:
eask exec ellspIf you see the following screen (no error), you successfully installed the language server! 🎉🥳
Updating environment variables... done v
Exporting environment variables... done v
18:45:59 [INFO ] Starting the language server...🔊 P.S. Nothing output afterward because the language server is waiting for the language client to connect!
To test the language server locally:
# Add link to current package
eask link add ellsp ./Then follow the same steps as installation:
# Install the proxy server.
eask exec install-ellsp
# Test the language server.
eask exec ellsp
