If you need a syntax checking plugin for Vim you might be interested in Syntastic's spiritual succesor, ALE. Although it shares no code with syntastic and it takes a very different approach to design, ALE can be considered a natural evolution of syntastic in terms of goals and functionality. Check it out, you probably won't be disappointed. 2. Introduction Syntastic is a syntax checking plugin for Vim created by Martin Grenfell. It runs files through external syntax checkers and displays any resulting errors to the user. This can be done on demand, or automatically as files are saved. If syntax errors are detected, the user is notified and is happy because they didn't have to compile their code or execute their script to find them. At the time of this writing, syntastic has checking plugins for ACPI Source Language, ActionScript, Ada, Ansible configurations, API Blueprint, AppleScript, AsciiDoc, Assembly languages, BEMHTML, Bro, Bourne shell, C, C++, C#, Cabal, Chef, CMake, CoffeeScript, Coco, Coq, CSS, Cucumber, CUDA, D, Dart, DocBook, Dockerfile, Dust, Elixir, Erlang, eRuby, Fortran, Gentoo metadata, GLSL, Go, Haml, Haskell, Haxe, Handlebars, HSS, HTML, Java, JavaScript, JSON, JSX, LESS, Lex, Limbo, LISP, LLVM intermediate language, Lua, Markdown, MATLAB, Mercury, NASM, Nix, Objective-C, Objective-C++, OCaml, Perl, Perl POD, PHP, gettext Portable Object, Raku, OS X and iOS property lists, Pug (formerly Jade), Puppet, Python, QML, R, Racket, RDF TriG, RDF Turtle, Relax NG, reStructuredText, RPM spec, Ruby, SASS/SCSS, Scala, Slim, SML, Solidity, Sphinx, SQL, Stylus, Tcl, TeX, Texinfo, Twig, TypeScript, Verilog, VHDL, Vim help, VimL, Vue.js, xHtml, XML, XSLT, XQuery, YACC, YAML, YANG data models, YARA rules, z80, Zope page templates, and Zsh. See the manual for details about the corresponding supported checkers (:help syntastic-checkers in Vim). A number of third-party Vim plugins also provide checkers for syntastic, for example: merlin, omnisharp-vim, rust.vim, syntastic-extras, syntastic-more, tsuquyomi, vim-crystal, vim-eastwood, and vim-swift. Below is a screenshot showing the methods that Syntastic uses to display syntax errors. Note that, in practise, you will only have a subset of these methods enabled. Errors are loaded into the location list for the corresponding window. When the cursor is on a line containing an error, the error message is echoed in the command window. Signs are placed beside lines with errors - note that warnings are displayed in a different color. There is a configurable statusline flag you can include in your statusline config. Hover the mouse over a line containing an error and the error message is displayed as a balloon. (not shown) Highlighting errors with syntax highlighting. Erroneous parts of lines can be highlighted. 3. Installation 3.1. Requirements Syntastic itself has rather relaxed requirements: it doesn't have any external dependencies, and it needs a version of Vim compiled with a few common features: autocmd, eval, file_in_path, modify_fname, quickfix, reltime, statusline, and user_commands.
