Bug ID: 158337
Summary: Use C++20 std::erase instead of std::removed followed
by erase
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
Now that C++20 is the baseline for LibreOffice code, it is possible to use C++
features that are only available since C++20.
In C++20, it is possible to use std::erase to erase all elements inside a
container that are equal to a certain "value". Also, it is possible to use
std:erase_if to erase all elements inside a container that satisfy the
predicate "pred".
For more information, see this description:
std::erase, std::erase_if (std::vector)
https://en.cppreference.com/w/cpp/container/vector/erase2
See this commit as an example: be1093cce53a3c34a67233391922674c7c62f4e3
Finding instances:
Using grep it is possible to find some instances. For example:
$ git grep std::remove|grep erase
This will not give all the instances, as sometime erase can be a few lines
before or after std::remove.
