From: Rian Hunter Date: Thu, 29 Jan 2015 23:00:39 +0000 (-0800) Subject: Correct shift amount on MODE_INSERT in tputc() X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=aba6c292af347588b9c2f5d1a400a6270b5a447f;p=st.git Correct shift amount on MODE_INSERT in tputc() When MODE_INSERT is set we'd shift characters on the same line forward before inserting our character in tputc(). This did not account for wide characters where width != 1. This patch makes it so we shift the correct amount. --- diff --git a/st.c b/st.c index 6a68c3c..1deb7bc 100644 --- a/st.c +++ b/st.c @@ -2676,8 +2676,8 @@ tputc(char *c, int len) { gp = &term.line[term.c.y][term.c.x]; } - if(IS_SET(MODE_INSERT) && term.c.x+1 < term.col) - memmove(gp+1, gp, (term.col - term.c.x - 1) * sizeof(Glyph)); + if(IS_SET(MODE_INSERT) && term.c.x+width < term.col) + memmove(gp+width, gp, (term.col - term.c.x - width) * sizeof(Glyph)); if(term.c.x+width > term.col) { tnewline(1);
