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. --- client.c | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) (limited to 'client.c') diff --git a/client.c b/client.c index 829b3d3c..4e756981 100644 --- a/client.c +++ b/client.c @@ -33,6 +33,7 @@ #include "tmux.h" +void client_send_environ(struct client_ctx *); void client_handle_winch(struct client_ctx *); int @@ -95,6 +96,8 @@ server_started: cctx->srv_in = buffer_create(BUFSIZ); cctx->srv_out = buffer_create(BUFSIZ); + if (cmdflags & CMD_SENDENVIRON) + client_send_environ(cctx); if (isatty(STDIN_FILENO)) { if (ioctl(STDIN_FILENO, TIOCGWINSZ, &ws) == -1) fatal("ioctl(TIOCGWINSZ)"); @@ -133,6 +136,19 @@ not_found: return (1); } +void +client_send_environ(struct client_ctx *cctx) +{ + char **var; + struct msg_environ_data data; + + for (var = environ; *var != NULL; var++) { + if (strlcpy(data.var, *var, sizeof data.var) >= sizeof data.var) + continue; + client_write_server(cctx, MSG_ENVIRON, &data, sizeof data); + } +} + int client_main(struct client_ctx *cctx) { @@ -242,8 +258,8 @@ client_msg_dispatch(struct client_ctx *cctx) if (hdr.size != sizeof printdata) fatalx("bad MSG_PRINT size"); buffer_read(cctx->srv_in, &printdata, sizeof printdata); - printdata.msg[(sizeof printdata.msg) - 1] = '\0'; + printdata.msg[(sizeof printdata.msg) - 1] = '\0'; cctx->errstr = xstrdup(printdata.msg); return (-1); case MSG_EXIT: -- cgit
