From 960786e7618942357c45e7e4c234f113e0aea9b1 Mon Sep 17 00:00:00 2001 From: Ryan Dammrose Date: Sat, 21 Apr 2018 12:10:00 +0200 Subject: push: colorize errors This is an attempt to resolve an issue I experience with people that are new to Git -- especially colleagues in a team setting -- where they miss that their push to a remote location failed because the failure and success both return a block of white text. An example is if I push something to a remote repository and then a colleague attempts to push to the same remote repository and the push fails because it requires them to pull first, but they don't notice because a success and failure both return a block of white text. They then continue about their business, thinking it has been successfully pushed. This patch colorizes the errors and hints (in red and yellow, respectively) so whenever there is a failure when pushing to a remote repository that fails, it is more noticeable. [jes: fixed a couple bugs, added the color.{advice,push,transport} settings, refactored to use want_color_stderr().] Signed-off-by: Ryan Dammrose ryandammrose@gmail.com Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano --- builtin/push.c | 44 +++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 43 insertions(+), 1 deletion(-) (limited to 'builtin') diff --git a/builtin/push.c b/builtin/push.c index 013c20d616..ac3705370e 100644 --- a/builtin/push.c +++ b/builtin/push.c @@ -12,12 +12,40 @@ #include "submodule.h" #include "submodule-config.h" #include "send-pack.h" +#include "color.h" static const char * const push_usage[] = { N_("git push [] [ [...]]"), NULL, }; +static int push_use_color = -1; +static char push_colors[][COLOR_MAXLEN] = { + GIT_COLOR_RESET, + GIT_COLOR_RED, /* ERROR */ +}; + +enum color_push { + PUSH_COLOR_RESET = 0, + PUSH_COLOR_ERROR = 1 +}; + +static int parse_push_color_slot(const char *slot) +{ + if (!strcasecmp(slot, "reset")) + return PUSH_COLOR_RESET; + if (!strcasecmp(slot, "error")) + return PUSH_COLOR_ERROR; + return -1; +} + +static const char *push_get_color(enum color_push ix) +{ + if (want_color_stderr(push_use_color)) + return push_colors[ix]; + return ""; +} + static int thin = 1; static int deleterefs; static const char *receivepack; @@ -337,8 +365,11 @@ static int push_with_options(struct transport *transport, int flags) fprintf(stderr, _("Pushing to %s\n"), transport->url); err = transport_push(transport, refspec_nr, refspec, flags, &reject_reasons); - if (err != 0) + if (err != 0) { + fprintf(stderr, "%s", push_get_color(PUSH_COLOR_ERROR)); error(_("failed to push some refs to '%s'"), transport->url); + fprintf(stderr, "%s", push_get_color(PUSH_COLOR_RESET)); + } err |= transport_disconnect(transport); if (!err) @@ -467,6 +498,7 @@ static void set_push_cert_flags(int *flags, int v) static int git_push_config(const char *k, const char *v, void *cb) { + const char *slot_name; int *flags = cb; int status; @@ -514,6 +546,16 @@ static int git_push_config(const char *k, const char *v, void *cb) else string_list_append(&push_options_config, v); return 0; + } else if (!strcmp(k, "color.push")) { + push_use_color = git_config_colorbool(k, v); + return 0; + } else if (skip_prefix(k, "color.push.", &slot_name)) { + int slot = parse_push_color_slot(slot_name); + if (slot < 0) + return 0; + if (!v) + return config_error_nonbool(k); + return color_parse(v, push_colors[slot]); } return git_default_config(k, v, NULL); -- cgit v1.2.3
