--- Note quickly written untested code (but compiles!), just to show an idea... This implements (i hope) curl(1) --stderr option in notmuch(1): --stderr <file> Redirect all writes to stderr to the specified file instead. If the file name is a plain '-', it is instead written to stdout. This would be useful in emacs interface. Please comment; I'll do help and manual page changes (and NEWS) if this is good idea :D Tomi notmuch.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/notmuch.c b/notmuch.c index f51a84f..3b8bd5d 100644 --- a/notmuch.c +++ b/notmuch.c @@ -21,6 +21,7 @@ */ #include "notmuch-client.h" +#include <fcntl.h> typedef int (*command_function_t) (notmuch_config_t *config, int argc, char *argv[]); @@ -259,6 +260,7 @@ main (int argc, char *argv[]) const char *command_name = NULL; command_t *command; char *config_file_name = NULL; + char *stderr_file = NULL; notmuch_config_t *config; notmuch_bool_t print_help=FALSE, print_version=FALSE; int opt_index; @@ -268,6 +270,7 @@ main (int argc, char *argv[]) { NOTMUCH_OPT_BOOLEAN, &print_help, "help", 'h', 0 }, { NOTMUCH_OPT_BOOLEAN, &print_version, "version", 'v', 0 }, { NOTMUCH_OPT_STRING, &config_file_name, "config", 'c', 0 }, + { NOTMUCH_OPT_STRING, &stderr_file, "stderr", 'c', 0 }, { 0, 0, 0, 0, 0 } }; @@ -295,6 +298,23 @@ main (int argc, char *argv[]) return 0; } + if (stderr_file) { + if (strcmp (stderr_file, "-") == 0) + dup2 (STDOUT_FILENO, STDERR_FILENO); + else { + int fd = open (stderr_file, O_WRONLY|O_CREAT|O_APPEND, 0644); + if (fd < 0) { + fprintf (stderr, "Error: Cannot redirect stderr to '%s': %s\n", + stderr_file, strerror(errno)); + return 1; + } + if (fd != STDERR_FILENO) { + dup2 (fd, STDERR_FILENO); + close (fd); + } + } + } + if (opt_index < argc) command_name = argv[opt_index]; -- 1.8.1.4
