Subject: [PATCH 0/5] Add struct strmap and associated utility functions
Date: Fri, 21 Aug 2020 18:52:24 +0000	[thread overview]
Message-ID: <pull.835.git.git.1598035949.gitgitgadget@gmail.com> (raw)

Here I introduce a new strmap type, which my new merge backed, merge-ort,
uses heavily. (I also made significant use of it in my changes to
diffcore-rename). This strmap type was based on Peff's proposal from a
couple years ago[1], but has additions that I made as I used it. I also
start the series off with a quick documentation improvement to hashmap.c to
differentiate between hashmap_free() and hashmap_free_entries(), since I
personally had difficulty understanding them and it affects how
strmap_clear()/strmap_free() are written.

The biggest issue I know about currently concerns the convenience functions
for a string->integer mapping. I wanted such a mapping that didn't need to
allocate an extra int but instead works by just type-casting the void*
pointer to an int instead. That all seems to work, but I needed a separate
name for that type, and the problem is that I couldn't come up with a good
one as you'll see in the last patch. Suggestions for better naming are very
much welcome. As are, of course, suggestions for other API or implementation
improvements.
