How it works with camelCase

The concept is simple, split camelCase words before checking them against a list of known English words.

• camelCase -> camel case • HTMLInput -> html input -- Notice that the I is associated with Input and not HTML • snake\_case\_words -> snake case words • camel2snake -> camel snake -- (the 2 is ignored)

Special case with ALL CAPS words

There are a few special cases to help with common spelling practices for ALL CAPS words.

Trailing s, ing, ies, es, ed are kept with the previous word.

• CURLs -> curls -- trailing s • CURLedRequest -> curled request -- trailing ed

Things to note

• This spellchecker is case insensitive. It will not catch errors like english which should be English. • The spellchecker uses a local word dictionary. It does not send anything outside your machine. • The words in the dictionary can and do contain errors. • There are missing words. • Only words longer than 3 characters are checked. "jsj" is not checked, while "jsja" is checked and will be marked as incorrect because it does not exist in any of the dictionaries. • All symbols and punctuation are ignored.

In Document Settings

It is possible to add spell check settings into your source code. This is to help with file specific issues that may not be applicable to the entire project.

All settings are prefixed with cSpell: or spell-checker:.…
