From: Johannes Schindelin Date: Mon, 21 Jul 2008 18:03:49 +0000 (+0100) Subject: Rename path_list to string_list X-Git-Tag: v1.6.0-rc1~87 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c455c87;p=git.git Rename path_list to string_list The name path_list was correct for the first usage of that data structure, but it really is a general-purpose string list. $ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list) $ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list) $ git mv path-list.h string-list.h $ git mv path-list.c string-list.c $ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path) $ perl -i -pe 's/path/string/g' string-list.[ch] $ git mv Documentation/technical/api-path-list.txt \ Documentation/technical/api-string-list.txt $ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths) ... and then fix all users of string-list to access the member "string" instead of "path". Documentation/technical/api-string-list.txt needed some rewrapping, too.
