From 6491274f60c175b89b02b6e4cd0c59b13717e2ec Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Sat, 8 Aug 2009 21:52:43 +0000 Subject: Infrastructure and commands to manage the environment for processes started within tmux. There is a global environment, copied from the external environment when the server is started and each sesssion has an (initially empty) session environment which overrides it. New commands set-environment and show-environment manipulate or display the environments. A new session option, update-environment, is a space-separated list of variables which are updated from the external environment into the session environment every time a new session is created - the default is DISPLAY. --- cmd-string.c | 28 +++++++++++++++------------- 1 file changed, 15 insertions(+), 13 deletions(-) (limited to 'cmd-string.c') diff --git a/cmd-string.c b/cmd-string.c index c12ac1d7..41b20948 100644 --- a/cmd-string.c +++ b/cmd-string.c @@ -59,21 +59,11 @@ int cmd_string_parse(const char *s, struct cmd_list **cmdlist, char **cause) { size_t p; - int ch, argc, rval, have_arg; - char **argv, *buf, *t, *u; + int ch, i, argc, rval, have_arg; + char **argv, *buf, *t; + const char *whitespace, *equals; size_t len; - if ((t = strchr(s, ' ')) == NULL && (t = strchr(s, '\t')) == NULL) - t = strchr(s, '\0'); - if ((u = strchr(s, '=')) != NULL && u < t) { - if (putenv(xstrdup(s)) != 0) { - xasprintf(cause, "assignment failed: %s", s); - return (-1); - } - *cmdlist = NULL; - return (0); - } - argv = NULL; argc = 0; @@ -147,6 +137,18 @@ cmd_string_parse(const char *s, struct cmd_list **cmdlist, char **cause) if (argc == 0) goto out; + for (i = 0; i < argc; i++) { + equals = strchr(argv[i], '='); + whitespace = argv[i] + strcspn(argv[i], " \t"); + if (equals == NULL || equals > whitespace) + break; + environ_put(&global_environ, argv[i]); + memmove(&argv[i], &argv[i + 1], argc - i - 1); + argc--; + } + if (argc == 0) + goto out; + *cmdlist = cmd_list_parse(argc, argv, cause); if (*cmdlist == NULL) goto out; -- cgit
