Issue: #26123
- Refactor and optimize the loop to make it shorter and faster
- Make it push elements into an arbitrary (templated) output iterator
- Make it a template on a separator type with the most used defaults
- Add a backward compatible signature to return `std::vector<std::string>`
- Add an alternative function `cmTokenizedView()` to return a vector of string views
Move `cmJoinImpl` from `cmStringAlgorithms.cxx` to the
`cmStringAlgorithms.h` as `cmJoinStrings`. Two existing overloads are
not suitable for reverse iterators due to the hardcoded type of the
first parameter.
The signature is similar to the generic (template) `cmJoin`. With
`enable_if` "magic", `cmJoinString` could be renamed to `cmJoin` in the
future.
Also, replace `getJoinedLength` with `std::accumulate`.
To handle safely the values used by CMake variables and properties,
introduce the class cmProp as a replacement from the simple pointer
to std::string instance.
cmJoin() is often used with std::string ranges. Generic implementation
uses std::ostringstream which is not optimal. With strings we can avoid
operator<<() and make much faster implementation. Additional 'initial'
argument is useful for cmStringCommand.cxx:HandleAppendCommand().
This adds the following functions to cmStringAlgorithms:
- `cmIsInternallyOn`
- `cmIsNOTFOUND`
- `cmIsOn`
- `cmIsOff`
The implementations were copied from the equivalent functions in cmSystemTools.
This adds the following functions to cmStringAlgorithms:
- `cmStrToLong`: moved from `cmSystemTools::StringToLong`
- `cmStrToULong`: moved from `cmSystemTools::StringToULong`
Overloads of the given functions for `std::string` are added as well.
This adds the following functions to `cmStringAlgorithms`:
- `cmIsSpace`
- `cmTrimWhitespace` (moved from `cmSystemTools::TrimWhitespace`)
- `cmEscapeQuotes` (moved from `cmSystemTools::EscapeQuotes`)
- `cmTokenize` (moved from `cmSystemTools::tokenize` and adapted to
accept `cm::string_view`)
