[jira] [Commented] (MINIFICPP-1289) Add range-v3

["Marton Szasz (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MINIFICPP-1289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17386163#comment-17386163 ] 

Marton Szasz commented on MINIFICPP-1289:
-----------------------------------------

I forgot to reply to this, but I guess better late than never. The error message is about the lambda type not satisfying the Sentinel concept. Actions can't be used with the | operator. Try ranges::actions::sort(matched_files_with_mtime, first_by_mtime_then_by_name);.

Now that the language upgrade is near the finishing line, I would say wait until it's in and go for the latest range-v3. We can't go directly for std::ranges, because it's not yet implemented in libstdc++ 8.x, which we still need to support to keep compatibility with debian buster.

> Useful library to raise the level of abstraction from iterators to ranges and provide useful related concepts.
