It is the unique test sequence implemented by all the emulators, and I think it is because they want be conforms with vttest which uses this sequence in some tests. --- st.c | 31 +++++++++++++++++++++++-------- 1 file changed, 23 insertions(+), 8 deletions(-) --- diff --git a/st.c b/st.c index 33a1501..693739e 100644 --- a/st.c +++ b/st.c @@ -123,6 +123,7 @@ enum escape_state { ESC_STR = 4, /* DSC, OSC, PM, APC */ ESC_ALTCHARSET = 8, ESC_STR_END = 16, /* a final string was encountered */ + ESC_TEST = 32, /* Enter in test mode */ }; enum window_state { @@ -289,7 +290,7 @@ static int tresize(int, int); static void tscrollup(int, int); static void tscrolldown(int, int); static void tsetattr(int*, int); -static void tsetchar(char*); +static void tsetchar(char *, Glyph *, int, int); static void tsetscroll(int, int); static void tswapscreen(void); static void tsetdirt(int, int); @@ -1182,7 +1183,7 @@ tmoveto(int x, int y) { } void -tsetchar(char *c) { +tsetchar(char *c, Glyph *attr, int x, int y) { static char *vt100_0[62] = { /* 0x41 - 0x7e */ "↑", "↓", "→", "←", "█", "▚", "☃", /* A - G */ 0, 0, 0, 0, 0, 0, 0, 0, /* H - O */ @@ -1197,17 +1198,17 @@ tsetchar(char *c) { /* * The table is proudly stolen from rxvt. */ - if(term.c.attr.mode & ATTR_GFX) { + if(attr->mode & ATTR_GFX) { if(c[0] >= 0x41 && c[0] <= 0x7e && vt100_0[c[0] - 0x41]) { c = vt100_0[c[0] - 0x41]; } } - term.dirty[term.c.y] = 1; - term.line[term.c.y][term.c.x] = term.c.attr; - memcpy(term.line[term.c.y][term.c.x].c, c, UTF_SIZ); - term.line[term.c.y][term.c.x].state |= GLYPH_SET; + term.dirty[y] = 1; + term.line[y][x] = *attr; + memcpy(term.line[y][x].c, c, UTF_SIZ); + term.line[y][x].state |= GLYPH_SET; } void @@ -1893,11 +1894,25 @@ tputc(char *c, int len) { fprintf(stderr, "esc unhandled charset: ESC ( %c\n", ascii); } term.esc = 0; + } else if(term.esc & ESC_TEST) { + if(ascii == '8') { /* DEC screen alignment test. */ + char E[UTF_SIZ] = "E"; + int x, y; + + for(x = 0; x < term.col; ++x) { + for(y = 0; y < term.row; ++y) + tsetchar(E, &term.c.attr, x, y); + } + } + term.esc = 0; } else { switch(ascii) { case '[': term.esc |= ESC_CSI; break; + case '#': + term.esc |= ESC_TEST; + break; case 'P': /* DCS -- Device Control String */ case '_': /* APC -- Application Program Command */ case '^': /* PM -- Privacy Message */ @@ -1988,7 +2003,7 @@ tputc(char *c, int len) { sel.bx = -1; if(IS_SET(MODE_WRAP) && term.c.state & CURSOR_WRAPNEXT) tnewline(1); /* always go to first col */ - tsetchar(c); + tsetchar(c, &term.c.attr, term.c.x, term.c.y); if(term.c.x+1 < term.col) tmoveto(term.c.x+1, term.c.y); else
