CSpell is a spell checker aimed at source code. It splits camelCase and snake_case identifiers into words for checking and combines per-programming-language dictionaries with project dictionaries, so unlike checkers for ordinary documents it produces few false positives on code. It is available as a command-line tool and a VS Code extension (Code Spell Checker), and words and paths to ignore are configured in cspell.json.
