From 16e0d5ec0603359f8dd72a2d91ff860cf97a8ee1 Mon Sep 17 00:00:00 2001 From: Vladimir Panteleev Date: Mon, 11 Sep 2017 11:15:56 +0000 Subject: [PATCH] ipc: Canonicalize output names in bar configuration Convert the output names specified in the "output" and "tray_output" fields in bar blocks in i3's configuration to the referred output's primary name. This allows specifying names other than the primary output's name in the given fields without changing the IPC protocol. --- src/ipc.c | 16 +++++++++++++--- 1 file changed, 13 insertions(+), 3 deletions(-) diff --git a/src/ipc.c b/src/ipc.c index b02b3fe4..274f6010 100644 --- a/src/ipc.c +++ b/src/ipc.c @@ -579,6 +579,11 @@ static void dump_bar_bindings(yajl_gen gen, Barconfig *config) { y(array_close); } +static char *canonicalize_output_name(char *name) { + Output *output = get_output_by_name(name, false); + return output ? output_primary_name(output) : name; +} + static void dump_bar_config(yajl_gen gen, Barconfig *config) { y(map_open); @@ -588,8 +593,13 @@ static void dump_bar_config(yajl_gen gen, Barconfig *config) { if (config->num_outputs > 0) { ystr("outputs"); y(array_open); - for (int c = 0; c < config->num_outputs; c++) - ystr(config->outputs[c]); + for (int c = 0; c < config->num_outputs; c++) { + /* Convert monitor names (RandR ≥ 1.5) or output names + * (RandR < 1.5) into monitor names.
