abseil-faster-strsplit-delimiter
|
|
================================
|
|
|
|
Finds instances of ``absl::StrSplit()`` or ``absl::MaxSplits()`` where the
|
|
delimiter is a single character string literal and replaces with a character.
|
|
The check will offer a suggestion to change the string literal into a
|
|
character. It will also catch code using ``absl::ByAnyChar()`` for just a
|
|
single character and will transform that into a single character as well.
|
|
|
|
These changes will give the same result, but using characters rather than
|
|
single character string literals is more efficient and readable.
|
|
|
|
Examples:
|
|
|
|
.. code-block:: c++
|
|
|
|
// Original - the argument is a string literal.
|
|
for (auto piece : absl::StrSplit(str, "B")) {
|
|
|
|
// Suggested - the argument is a character, which causes the more efficient
|
|
// overload of absl::StrSplit() to be used.
|
|
for (auto piece : absl::StrSplit(str, 'B')) {
|
|
|
|
|
|
// Original - the argument is a string literal inside absl::ByAnyChar call.
|
|
for (auto piece : absl::StrSplit(str, absl::ByAnyChar("B"))) {
|
|
|
|
// Suggested - the argument is a character, which causes the more efficient
|
|
// overload of absl::StrSplit() to be used and we do not need absl::ByAnyChar
|
|
// anymore.
|
|
for (auto piece : absl::StrSplit(str, 'B')) {
|
|
|
|
|
|
// Original - the argument is a string literal inside absl::MaxSplits call.
|
|
for (auto piece : absl::StrSplit(str, absl::MaxSplits("B", 1))) {
|
|
|
|
// Suggested - the argument is a character, which causes the more efficient
|
|
// overload of absl::StrSplit() to be used.
|
|
for (auto piece : absl::StrSplit(str, absl::MaxSplits('B', 1))) {
