CodeMirror +is a JavaScript component that provides a code editor in the browser. When +a mode is available for the language you are coding in, it will color your +code, and optionally help with indentation. + +# Upgrade + +Currently used version is 5.58.1. To upgrade: download a new version of +CodeMirror from the project's page [1] and replace all JavaScript and +CSS files inside the codemirror directory [2]. + +Then to recreate codemirror.bundle.js: + > cd devtools/client/shared/sourceeditor + > npm install + > npm run build + +When investigating an issue in CodeMirror, you might want to have a non-minified bundle. +You can do this by running `npm run build-unminified` instead of `npm run build`. + +To confirm the functionality run mochitests for the following components: + + * sourceeditor + * debugger + * styleditor + * netmonitor + * webconsole + +The sourceeditor component contains imported CodeMirror tests [3]. + + * Some tests were commented out because we don't use that functionality + within Firefox (for example Ruby editing mode). Be careful when updating + files test/codemirror.html and test/vimemacs.html; they were modified to + co-exist with Mozilla's testing infrastructure. Basically, vimemacs.html + is a copy of codemirror.html but only with VIM and Emacs mode tests + enabled. + * In cm_comment_test.js comment out fallbackToBlock and fallbackToLine + tests. + * The search addon (search.js) was slightly modified to make search + UI localizable (see patch below). + +Other than that, we don't have any Mozilla-specific patches applied to +CodeMirror itself. + +# Addons + +To install a new CodeMirror addon add it to the codemirror directory, +jar.mn [4] file and editor.js [5].
