CodeMirror Spell Checker

Spell checking so simple, you can set up in 60 seconds. It will highlight any misspelled words in light red. Works great in conjunction with other CodeMirror modes, like GitHub Flavored Markdown.

Fork

This is a fork of sparksuite's codemirror-spell-checker.

Added fixes:

* Non-ASCII characters (e.g. foreign character sets) are ignored.
* Numbers aren't treated as spelling error.
* 27D isn't treated as a spelling error (for 27 dimensions).
* Switch to hunspell-en_US-large dictionary
via NPM package hunspell-dict-en-us

Quick start


Once CodeMirror is installed and loaded, first provide CodeMirror Spell Checker with the correct CodeMirror function. Then, just set the primary mode to "spell-checker" and the backdrop mode to your desired mode. Be sure to load/require overlay.min.js if you haven't already.

`JS
CodeMirrorSpellChecker({
codeMirrorInstance: CodeMirror,
});

CodeMirror.fromTextArea(document.getElementById("textarea"), {
mode: "spell-checker",
backdrop: "gfm" // Your desired mode
});
`

That's it!

Customizing


You can customize the misspelled word appearance by updating the CSS. All misspelled words will have the .cm-spell-error class.

`CSS
.CodeMirror .cm-spell-error{
/ Your styling here /
}
`

Configuration

- customWords: Custom array of words that will not be designated as misspelled. Defaults to an empty array.

`JavaScript
// Most options demonstrate the non-default behavior
CodeMirrorSpellChecker({
codeMirrorInstance: CodeMirror,
customWords: ["CodeMirror", "GitHub"],
});
