From 94351118c0a820002b093598e7fac5bdf3c0291f Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sun, 24 Feb 2008 17:17:14 -0500 Subject: [PATCH] make alias lookup a public, procedural function This converts git_config_alias to the public alias_lookup function. Because of the nature of our config parser, we still have to rely on setting static data. However, that interface is wrapped so that you can just say value = alias_lookup(key); Signed-off-by: Jeff King Signed-off-by: Junio C Hamano --- Makefile | 3 ++- alias.c | 22 ++++++++++++++++++++++ cache.h | 2 ++ git.c | 17 +++-------------- 4 files changed, 29 insertions(+), 15 deletions(-) create mode 100644 alias.c diff --git a/Makefile b/Makefile index d33a556ff..b460bb216 100644 --- a/Makefile +++ b/Makefile @@ -327,7 +327,8 @@ LIB_OBJS = \ alloc.o merge-file.o path-list.o help.o unpack-trees.o $(DIFF_OBJS) \ color.o wt-status.o archive-zip.o archive-tar.o shallow.o utf8.o \ convert.o attr.o decorate.o progress.o mailmap.o symlinks.o remote.o \ - transport.o bundle.o walker.o parse-options.o ws.o archive.o + transport.o bundle.o walker.o parse-options.o ws.o archive.o \ + alias.o BUILTIN_OBJS = \ builtin-add.o \ diff --git a/alias.c b/alias.c new file mode 100644 index 000000000..116cac87c --- /dev/null +++ b/alias.c @@ -0,0 +1,22 @@ +#include "cache.h" + +static const char *alias_key; +static char *alias_val; +static int alias_lookup_cb(const char *k, const char *v) +{ + if (!prefixcmp(k, "alias.") && !strcmp(k+6, alias_key)) { + if (!v) + return config_error_nonbool(k); + alias_val = xstrdup(v); + return 0; + } + return 0; +} + +char *alias_lookup(const char *alias) +{ + alias_key = alias; + alias_val = NULL; + git_config(alias_lookup_cb); + return alias_val; +} diff --git a/cache.h b/cache.h index fa5a9e523..1e9c93729 100644 --- a/cache.h +++ b/cache.h @@ -765,4 +765,6 @@ int pathspec_match(const char **spec, char *matched, const char *filename, int s int report_path_error(const char *ps_matched, const char **pathspec, int prefix_offset); void overlay_tree_on_cache(const char *tree_name, const char *prefix); +char *alias_lookup(const char *alias); + #endif /* CACHE_H */ diff --git a/git.c b/git.c index 0cb86884d..8f08b1229 100644 --- a/git.c +++ b/git.c @@ -87,19 +87,6 @@ static int handle_options(const char*** argv, int* argc, int* envchanged) return handled; } -static const char *alias_command; -static char *alias_string; - -static int git_alias_config(const char *var, const char *value) -{ - if (!prefixcmp(var, "alias.") && !strcmp(var + 6, alias_command)) { - if (!value) - return config_error_nonbool(var); - alias_string = xstrdup(value); - } - return 0; -} - static int split_cmdline(char *cmdline, const char ***argv) { int src, dst, count = 0, size = 16; @@ -159,11 +146,13 @@ static int handle_alias(int *argcp, const char ***argv) const char *subdir; int count, option_count; const char** new_argv; + const char *alias_command; + char *alias_string; subdir = setup_git_directory_gently(&nongit); alias_command = (*argv)[0]; - git_config(git_alias_config); + alias_string = alias_lookup(alias_command); if (alias_string) { if (alias_string[0] == '!') { if (*argcp > 1) { -- 2.26.2
