Defined in header <cparse/Generator.hh>
virtual std::string convertLowerCase( std::string const& base ) const noexcept;
Returns a copy of base with every ASCII letter replaced by its lower-case equivalent. Non-letter bytes and non-ASCII bytes are passed through unchanged.
Implemented via std::transform with std::tolower — locale-free, byte-for-byte.
Parameters
| Parameter | Description |
|---|---|
base | The input string. Not mutated. |
Return value
A new string of the same length as base.
Exceptions
noexcept.
Notes
Byte-oriented, not Unicode-aware. For a UTF-8 string, the ASCII letters are lower-cased but multi-byte sequences (Turkish İ, German ß, etc.) are passed through untouched — you will not get i and ß/ss where a locale-aware routine would.
For file extensions and other identifier fragments where only ASCII matters, this is exactly what you want.
