Note that Hercules, besides vanquishing the Hydra, will still serve his original purpose, calling his proper command. The Hydra is vanquished once Hercules, any binding that isn’t the Hydra’s head, arrives. hydraĪnother thing that’s really useful, not just related to LSP, is the hydra package, which is described very well by its author: ) ( use-package lsp-ui :requires lsp-mode flycheck :config ( setq lsp-ui-doc-enable t lsp-ui-doc-use-childframe t lsp-ui-doc-position 'top lsp-ui-doc-include-signature t lsp-ui-sideline-enable nil lsp-ui-flycheck-enable t lsp-ui-flycheck-list-position 'right lsp-ui-flycheck-live-reporting t lsp-ui-peek-enable t lsp-ui-peek-list-width 60 lsp-ui-peek-peek-height 25 ) ( add-hook 'lsp-mode-hook 'lsp-ui-mode )) 4.2. :config ( setq lsp-prefer-flymake nil ) Prefer using lsp-ui (flycheck) over flymake. My configuration relies on flycheck being set up: Lsp-ui adds higher level UI modules, like documentation child frame while hovering a symbol, integration with flycheck, and enables inline definition and references peeking - just to name a few things. This section is dedicated to extra features and niceties that I find makes LSP more usable and powerful. emacs.d is freely available for the complete LSP configuration, and lots of other stuff related to Emacs. Take a look here for more information about extensions and features.Įdit : My. lsp-describe-session: describes current LSP session and its capabilities.

lsp-describe-thing-at-point: displays the full documentation of the thing at point.The results are displayed this way due to the helm and helm-xref packages. Next, let’s try to find references of parse_args() by placing the cursor on it and The minibuffer will display (the PID will differ): Usually the last option is what you want. Import project by selecting root directory interactively.Do nothing and ask me again when opening other files from the folder.Do not ask more for the current project (select ignore path interactively).Do not ask more for the current project (add “~/git/vermin/” to lsp-session-folder-blacklist).In this case I’m testing using my vermin project: When LSP does not know which project to associate a file, usually the first time visiting a file, it will ask what to do. If no running language server is handling the particular project, a new one will be spun up to communicate with lsp-mode. Using LSP is easy: open a source code file with one of the major modes associated the lsp hook.

Emacs configurationįirst install the lsp-mode package, which is the LSP client that we will be using: Additionally, I use macOS but the installation commands can easily be translated to other solutions and other OSs. It is assumed that Emacs version 25.1 or later is already installed and setup for basic usage, and that you’re familiar with editing its config file. In this article, I will go over the configuration and setup of Emacs for LSP support of C++, Python, and Rust. LSP reduces an \(m \times n\) complexity problem to \(m + n\): the latter refers to only needing a language server for each language and a client for each IDE, whereas the former means that for every language each IDE would require, in most cases, standalone support. Adoption is already very good across the field. When running, all editors and IDEs supporting LSP will be able to employ its features. It tackles the code intelligence problem quite nicely: To support a given programming language with LSP, a language server program must be implemented. The Language Server protocol is used between a tool (the client) and a language smartness provider (the server) to integrate features like auto complete, go to definition, find all references and alike into the tool. Having used Emacs since 2006, I never found a good, reliable, and general enough solution to code completion, symbol cross referencing, go-to definition until I stumbled upon the Language Server Protocol ( LSP).
