CLion helps you make sure that all your source code, including textual strings, comments, and literals,
and commit messages, is spelt correctly. For this purpose, CLion suggests a dedicated Typo inspection,
which is supported by the corresponding bundled plugin and is enabled by default.
Correctness of spelling is checked against pre-defined dictionaries (as of now,
english.dic), and any number of user-defined custom dictionaries.
A user dictionary is a textual file with the
containing the words you want to be accepted by the Typo inspection as correct. The words
in such dictionaries are delimited with the newline.
Besides that, you can define your own list of words that will be skipped by the inspection. You can add words to this list "on-the-fly", or intentionally while setting up your spellchecker options.
With the Typo inspection enabled, CLion detects and highlights words not included in dictionaries and user's words list. It up to the user to provide correct spelling, accept word as is, or disable inspection.If a word is accepted, it will be added to the user's words list, and skipped by the spellchecker in future. If inspection is disabled, all typos will be ignored.
In the textual strings and comments, spelling of a word at caret can be changed to a correct one. In the contexts that enable Rename refactoring, the inspection suggests to rename all occurrences of a symbol.
