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-new-session.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'cmd-new-session.c') diff --git a/cmd-new-session.c b/cmd-new-session.c index c1ba6e30..61f18c8f 100644 --- a/cmd-new-session.c +++ b/cmd-new-session.c @@ -40,7 +40,7 @@ struct cmd_new_session_data { const struct cmd_entry cmd_new_session_entry = { "new-session", "new", "[-d] [-n window-name] [-s session-name] [command]", - CMD_STARTSERVER|CMD_CANTNEST, 0, + CMD_STARTSERVER|CMD_CANTNEST|CMD_SENDENVIRON, 0, cmd_new_session_init, cmd_new_session_parse, cmd_new_session_exec, @@ -108,6 +108,8 @@ cmd_new_session_exec(struct cmd *self, struct cmd_ctx *ctx) { struct cmd_new_session_data *data = self->data; struct session *s; + struct environ env; + const char *update; char *overrides, *cmd, *cwd, *cause; int detached; u_int sx, sy; @@ -184,13 +186,20 @@ cmd_new_session_exec(struct cmd *self, struct cmd_ctx *ctx) else cmd = options_get_string(&global_s_options, "default-command"); + /* Construct the environment. */ + environ_init(&env); + update = options_get_string(&global_s_options, "update-environment"); + if (ctx->cmdclient != NULL) + environ_update(update, &ctx->cmdclient->environ, &env); + /* Create the new session. */ - s = session_create(data->newname, cmd, cwd, sx, sy, &cause); + s = session_create(data->newname, cmd, cwd, &env, sx, sy, &cause); if (s == NULL) { ctx->error(ctx, "create session failed: %s", cause); xfree(cause); return (-1); } + environ_free(&env); if (data->winname != NULL) { xfree(s->curw->window->name); -- cgit
