lsp-bridge

The goal of lsp-bridge is to implement the fastest LSP client in the Emacs ecosystem.

Using Python multithreading techniques, lsp-bridge builds a high-speed cache between Emacs and the LSP server, ensuring that Emacs never gets stuck while providing a smooth and seamless code completion experience.

Installation

Install Emacs 28 or higher version
Install Python dependencies: epc, orjson, sexpdata, six, paramiko, please choose one of the following methods to install Python dependencies

PyPy (On Linux, we strongly recommend using PyPy instead of CPython for a 5x performance boost): pypy3 -m pip install epc sexpdata six paramiko
CPython: (Windows and MacOS users please use CPython) pip3 install epc orjson sexpdata six paramiko (orjson is optional, orjson is based on Rust, providing faster JSON parsing performance)

Install Elisp dependencies:

Download this repository using git clone, and replace the load-path path in the configuration below.
Add the following code to your configuration file ~/.emacs:

(add-to-list ‘load-path "<path-to-lsp-bridge>")

(require ’yasnippet)
(yas-global-mode 1)

(require ‘lsp-bridge)
(global-lsp-bridge-mode)

Please note that:

When using lsp-bridge, please first disable other completion plugins such as lsp-mode, eglot, company, corfu, etc. Lsp-bridge provides a complete solution from completion backend, frontend to multi-backend fusion.
When the completion menu pops up, acm-mode will be automatically enabled, and when the completion menu disappears, acm-mode will be automatically disabled. Please do not manually add acm-mode to any mode-hook or manually execute acm-mode.

Local Usage

Lsp-bridge works out of the box. After installing the corresponding LSP server and mode plugin for the language, you can start coding directly without any additional settings.

It should be noted that lsp-bridge has three scanning modes:

When the .git directory is detected (determined by the command git rev-parse --is-inside-work-tree), lsp-bridge will scan the entire directory to provide completion.
When the .git directory is not detected, lsp-bridge only provides single-file completion for the opened file.
Custom lsp-bridge-get-project-path-by-filepath function, where the input parameter is the path string of the opened file and the output parameter is the project directory path. Lsp-bridge will provide completion based on the output directory path.

Remote Usage

lsp-bridge can also provide code syntax completion for files on a remote server, similar to VSCode. Providing remote code completion is very useful when dealing with large and complex software that requires high resource demands or has complex environment configuration. The following are the steps to configure remote code completion:

Install lsp-bridge and the corresponding LSP server on the remote server.
Start the lsp-bridge service: pypy3 lsp-bridge/lsp_bridge.py (If you are using CPython, please use python3 lsp-bridge/lsp_bridge.py)
Use the command lsp-bridge-open-remote-file to open the remote file and enter the username, server IP, ssh port (default: 22), and file path, such as user@ip:[ssh_port]/path/file.

Once the remote file is opened, lsp-bridge will automatically display the code completion menu. The remote completion principle of lsp-bridge is as follows:

Login to the remote server with SSH authentication and access and edit the remote file.
When editing the remote file locally, incremental diff sequences are sent to the lsp-bridge server in real-time. The server will rebuild the latest content of the file based on the incremental diff sequence and call the LSP server to complete the syntax calculation.
After calculating the LSP completion menu items, lsp-bridge will send the completion data to the local computer and render the completion menu.

If the completion menu does not appear, log in to the remote server and check the terminal output of lsp_bridge.py. Generally, incomplete installation of the service-side LSP server is the cause.

lsp-bridge first looks for the content of the first *.pub file in the ~/.ssh directory as the public key credential for logging into the remote server. If public key login fails, the user will be prompted to enter the login password. lsp-bridge does not store the server login password in a file. To avoid repeatedly entering the password, it is recommended that you use the public key method to log in to the remote server.

Customize language server configuration

The configuration for the LSP server of each language in lsp-bridge is stored in lsp-bridge/langserver.

In most cases, you can customize the server configuration according to the following priority order:

lsp-bridge-get-single-lang-server-by-project: A user-defined function that takes project-path and file-path as input parameters and returns the corresponding LSP server string. You can query the names of all LSP servers in the lsp-bridge-single-lang-server-mode-list list. By default, this function returns nil.
lsp-bridge-single-lang-server-extension-list: Returns the server based on the file extension, for example, when opening a *.wxml file, we will use the wxml LSP server for completion.
lsp-bridge-single-lang-server-mode-list: Returns the corresponding server based on Emacs’s major-mode.

If you are writing JavaScript code, you may need to customize multiple server configurations:

lsp-bridge-get-multi-lang-server-by-project: A user-defined function that takes project-path and file-path as input parameters and returns the multiple server configuration names. You can search for them in the subdirectory lsp-bridge/multiserver.
lsp-bridge-multi-lang-server-extension-list: Returns multiple server configuration names based on the file extension. For example, when opening a *.vue file, we will use volar_emmet to simultaneously utilize volar and emmet-ls for completion.
lsp-bridge-multi-lang-server-mode-list: Returns the corresponding multiple server configuration names based on Emacs‘s major-mode.

For example, we can enable the Deno LSP server for Deno scripts with the following configuration:

(setq lsp-bridge-get-multi-lang-server-by-project
      (lambda (project-path filepath)
        ;; If typescript file include deno.land url, then use Deno LSP server.
        (save-excursion
          (when (string-equal (file-name-extension filepath) "ts")
            (dolist (buf (buffer-list))
              (when (string-equal (buffer-file-name buf) filepath)
                (with-current-buffer buf
                  (goto-char (point-min))
                  (when (search-forward-regexp (regexp-quote "from \"https://deno.land") nil t)
                    (return "deno")))))))))

Customize language server configuration file

Copy the configuration files in lsp-bridge/langserver or lsp-bridge/multiserver to lsp-bridge-user-langserver-dir or lsp-bridge-user-multiserver-dir for customization. Lsp-bridge will prioritize reading the configuration files in lsp-bridge-user-langserver-dir or lsp-bridge-user-multiserver-dir.

We can set the value of lsp-bridge-user-langserver-dir or lsp-bridge-user-multiserver-dir before starting lsp-bridge-mode to achieve different project-specific configuration files.

(defun enable-lsp-bridge()
  (when-let* ((project (project-current))
              (project-root (nth 2 project)))
    (setq-local lsp-bridge-user-langserver-dir project-root
                lsp-bridge-user-multiserver-dir project-root))
  (lsp-bridge-mode))

Add support for new language?

Create a configuration file in the lsp-bridge/langserver directory. For example, pyright.json is the configuration file for the pyright server (use pyright_windows.json for Windows and pyright_darwin.json for macOS).
Add (mode . server_name) to the lsp-bridge-single-lang-server-mode-list option in the lsp-bridge.el file, for example, (python-mode . "pyright").
Add a new mode-hook to the lsp-bridge-default-mode-hooks option in the lsp-bridge.el file.
Add a new indentation variable to the lsp-bridge-formatting-indent-alist option in the lsp-bridge.el file.

We welcome patches to help us support more LSP servers. Thank you for your help!

Supported language servers

You need to install the LSP server corresponding to each programming language, then lsp-bridge can provide code completion service.

If your language supports mixed multi-language servers, it is recommended to check the multi-language server definition under multiserver, and install multiple LSP servers to get a more complete experience. For example, for the Python language, according to the default pyright-background-analysis_ruff.json definition, you should install pyright and ruff.

Please read below articles first:

Then turn on develop option lsp-bridge-enable-log and happy hacking! ;)

Report bug

For some common problems, please read Wiki first.

Please use emacs -q and load a minimal setup with only lsp-bridge to verify that the bug is reproducible. If emacs -q works fine, probably something is wrong with your Emacs config.

If the problem still exists, please report it here with *lsp-bridge* buffer content, it contains many clues that can help us locate the problem faster.

If you get a segfault error, please use the following way to collect crash information:
1. Install gdb and turn on option lsp-bridge-enable-debug
2. Use the command lsp-bridge-restart-process to restart the LSP-BRIDGE process
3. Send issue with *lsp-bridge* buffer content when next crash
If you get other errors, please use the following way to collection information:
1. turn on option lsp-bridge-enable-log
2. Use the command lsp-bridge-restart-process to restart the LSP-BRIDGE process
3. Send issue with *lsp-bridge* buffer content
