From 65add0a31189e6257c521df3889f6d9a6d1183f2 Mon Sep 17 00:00:00 2001 From: Pieter Noordhuis Date: Wed, 15 Dec 2010 15:59:04 +0100 Subject: [PATCH] Improved raw output mode Raw output mode is selected by default when STDOUT is not a tty. For ttys, raw output can be forced using the option "--raw". --- src/redis-cli.c | 94 ++++++++++++++++++++++++++++++++++--------------- 1 file changed, 65 insertions(+), 29 deletions(-) diff --git a/src/redis-cli.c b/src/redis-cli.c index 4d698158..1e28fb3d 100644 --- a/src/redis-cli.c +++ b/src/redis-cli.c @@ -60,12 +60,11 @@ static struct config { int shutdown; int monitor_mode; int pubsub_mode; - int raw_output; /* output mode per command */ - int tty; /* flag for default output format */ int stdinarg; /* get last arg from stdin.
