From cb564bb427b9db5b1e48a74e6b818454f7ab0c77 Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Sat, 11 Sep 2010 16:19:22 +0000 Subject: Use UTF-8 line drawing characters on UTF-8 terminals. Fixes some stupid terminals (I'm looking at you, putty) which disable the vt100 ACS mode switching sequences in UTF-8 mode. Also on terminals without ACS at all, use ASCII equivalents where obvious. --- tty.c | 55 +++++++++++++++++++------------------------------------ 1 file changed, 19 insertions(+), 36 deletions(-) (limited to 'tty.c') diff --git a/tty.c b/tty.c index bf0a48b0..642b9766 100644 --- a/tty.c +++ b/tty.c @@ -31,8 +31,6 @@ void tty_read_callback(struct bufferevent *, void *); void tty_error_callback(struct bufferevent *, short, void *); -void tty_fill_acs(struct tty *); - int tty_try_256(struct tty *, u_char, const char *); int tty_try_88(struct tty *, u_char, const char *); @@ -48,6 +46,9 @@ void tty_emulate_repeat( void tty_cell(struct tty *, const struct grid_cell *, const struct grid_utf8 *); +#define tty_use_acs(tty) \ + (tty_term_has(tty, TTYC_ACSC) && !((tty)->flags & TTY_UTF8)) + void tty_init(struct tty *tty, int fd, char *term) { @@ -143,8 +144,6 @@ tty_open(struct tty *tty, const char *overrides, char **cause) tty_keys_init(tty); - tty_fill_acs(tty); - return (0); } @@ -201,7 +200,8 @@ tty_start_tty(struct tty *tty) memcpy(&tty->cell, &grid_default_cell, sizeof tty->cell); tty_putcode(tty, TTYC_RMKX); - tty_putcode(tty, TTYC_ENACS); + if (tty_use_acs(tty)) + tty_putcode(tty, TTYC_ENACS); tty_putcode(tty, TTYC_CLEAR); tty_putcode(tty, TTYC_CNORM); @@ -242,7 +242,8 @@ tty_stop_tty(struct tty *tty) return; tty_raw(tty, tty_term_string2(tty->term, TTYC_CSR, 0, ws.ws_row - 1)); - tty_raw(tty, tty_term_string(tty->term, TTYC_RMACS)); + if (tty_use_acs(tty)) + tty_raw(tty, tty_term_string(tty->term, TTYC_RMACS)); tty_raw(tty, tty_term_string(tty->term, TTYC_SGR0)); tty_raw(tty, tty_term_string(tty->term, TTYC_RMKX)); tty_raw(tty, tty_term_string(tty->term, TTYC_CLEAR)); @@ -257,30 +258,6 @@ tty_stop_tty(struct tty *tty) fcntl(tty->fd, F_SETFL, mode & ~O_NONBLOCK); } -void -tty_fill_acs(struct tty *tty) -{ - const char *ptr; - - memset(tty->acs, 0, sizeof tty->acs); - if (!tty_term_has(tty->term, TTYC_ACSC)) - return; - - ptr = tty_term_string(tty->term, TTYC_ACSC); - if (strlen(ptr) % 2 != 0) - return; - for (; *ptr != '\0'; ptr += 2) - tty->acs[(u_char) ptr[0]] = ptr[1]; -} - -u_char -tty_get_acs(struct tty *tty, u_char ch) -{ - if (tty->acs[ch] != '\0') - return (tty->acs[ch]); - return (ch); -} - void tty_close(struct tty *tty) { @@ -360,11 +337,17 @@ tty_puts(struct tty *tty, const char *s) void tty_putc(struct tty *tty, u_char ch) { - u_int sx; + const char *acs; + u_int sx; - if (tty->cell.attr & GRID_ATTR_CHARSET) - ch = tty_get_acs(tty, ch); - bufferevent_write(tty->event, &ch, 1); + if (tty->cell.attr & GRID_ATTR_CHARSET) { + acs = tty_acs_get(tty, ch); + if (acs != NULL) + bufferevent_write(tty->event, acs, strlen(acs)); + else + bufferevent_write(tty->event, &ch, 1); + } else + bufferevent_write(tty->event, &ch, 1); if (ch >= 0x20 && ch != 0x7f) { sx = tty->sx; @@ -997,7 +980,7 @@ tty_reset(struct tty *tty) if (memcmp(gc, &grid_default_cell, sizeof *gc) == 0) return; - if (tty_term_has(tty->term, TTYC_RMACS) && gc->attr & GRID_ATTR_CHARSET) + if ((gc->attr & GRID_ATTR_CHARSET) && tty_use_acs(tty)) tty_putcode(tty, TTYC_RMACS); tty_putcode(tty, TTYC_SGR0); memcpy(gc, &grid_default_cell, sizeof *gc); @@ -1234,7 +1217,7 @@ tty_attributes(struct tty *tty, const struct grid_cell *gc) } if (changed & GRID_ATTR_HIDDEN) tty_putcode(tty, TTYC_INVIS); - if (changed & GRID_ATTR_CHARSET) + if ((changed & GRID_ATTR_CHARSET) && tty_use_acs(tty)) tty_putcode(tty, TTYC_SMACS); } -- cgit v1.2.3
