From 5dbcca49263be094fc38159c297458ae323ef647 Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Wed, 1 May 2024 20:45:39 +0200 Subject: support colons in SGR character attributes Patch by Mikhail Kot With some modifications to behave more like xterm (see note below). Example: printf '\033[48;2;255:0:0mtest\n' https://invisible-island.net/xterm/ctlseqs/ctlseqs.html Some notes: "CSI Pm m Character Attributes (SGR). [...] o xterm allows either colons (standard) or semicolons (legacy) to separate the subparameters (but after the first colon, colons must be used). --- st.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/st.c b/st.c index b9f66e7..57c6e96 100644 --- a/st.c +++ b/st.c @@ -1132,6 +1132,7 @@ csiparse(void) { char *p = csiescseq.buf, *np; long int v; + int sep = ';'; /* colon or semi-colon, but not both */ csiescseq.narg = 0; if (*p == '?') { @@ -1149,7 +1150,9 @@ csiparse(void) v = -1; csiescseq.arg[csiescseq.narg++] = v; p = np; - if (*p != ';' || csiescseq.narg == ESC_ARG_SIZ) + if (sep == ';' && *p == ':') + sep = ':'; /* allow override to colon once */ + if (*p != sep || csiescseq.narg == ESC_ARG_SIZ) break; p++; } -- cgit v1.2.3
