In T#, do nothing if SUPPRESS_BOTTOM_REG is non-zero. In T#, always mark the current vertical position and return to it before turning traps on again. Thu Jul 26 02:54:32 1990 James Clark (jjc at yquem) * troff/node.c, troff/node.h: In classes derived from node, replace prev_char_width method by last_char_node method. * troff/env.c (environment::get_prev_char_width): Use node::last_char_node rather than node::get_prev_char_width. * Makefile: Added comment about -fno-inline on 68030-based Apollos. * troff/reg.c (number_format_to_ascii), eqn/delim.c (DELIM_TABLE_SIZE), tty/tty.c (tty_font::load_tty_font), dvi/tfmtodit.c (main): Cast expressions using sizeof to int. * dvi/dvi.c (dvi_font::handle_x_command): Avoid long->int warnings. * macros/tmac.e (TS): Don't move @f back past the current position.

This works around a bug on the 68030 based Apollo using g++ 1.37.1. * tbl/table.h (class table): Add `keep' member. * tbl/table.c (table::table): Initialize `keep'. (table::add_vertical_rule): Set `keep' to 1. (table::do_top): Only emit table keep macro is `keep' is non-zero. (table::do_bottom): Likewise for table release macro.

(ps_printer::set_style): Likewise. (ps_output::put_number): Use 1 + INT_DIGITS + 1 instead of 12. * tty/devascii/R.proto: Map fm onto '. * tty/devlatin1/R.proto: Likewise. Sat Jul 21 12:45:07 1990 James Clark (jjc at yquem) * tbl/table.c: Use ' instead of DELIMITER_CHAR in places where the argument to \w is at a different input level. * tbl/table.c (table::init_output): Define a new macro REPEATED_VPT_MACRO, like vpt but if in a diversion also transparently outputs itself. (table::define_bottom_macro): Use REPEATED_VPT_MACRO instead of vpt. (table::do_row): Likewise. * tbl/table.c (vertical_rule::print): Prefix the .sp -1 line with TRANSPARENT_STRING_NAME. * tbl/table.c (table::init_output): In the table release macro print an error message and don't produce any output if after issuing the need request the table still will not fit. Also remove the diversion after bringing it back. * tbl/table.c (table::init_output): Define a new macro REPEATED_MARK_MACRO, like mk but if in a diversion also transparently outputs itself. (table::do_row): Mark row_top_reg using REPEATED_MARK_MACRO. This is necessary because .TH might not call .T#. (table::do_top): Likewise TOP_REG. (table::define_bottom_macro): If TOP_REG is no longer valid, use #T - DOUBLE_LINE_SEP rather than #T. This is necessary because the table header might contain just the two top rules.

Thu Jul 19 12:07:16 1990 James Clark (jjc at yquem) * troff/div.c: New number register .pn returns the number of the next page as set by the pn request. * macros/tmac.an: Redid headers and footers. Number each manual entry starting from 1 unless \nC is > 0, like Sun. Added an optional 5th argument to .TH which specifies the manual name and appears in the center of the header. Understand the X, P and D registers like Sun.

Instead, flush pending lines from environment after END_TRAP token seen, but only if there aren't any more traps still unfinished. * troff/token.h: Remove TOKEN_FLUSH_PENDING_LINES. Sun Jul 15 10:50:08 1990 James Clark (jjc at yquem) * troff/env.c: Rename the `retain_size' member of class pending_output_line to `no_fill'. * troff/env.c (title): When the line is output, make the retain_size argument !fill. * troff/node.h: Add `hyphenated' member to struct breakpoint. * troff/node.c (space_node::get_breakpoints), (dbreak_node::get_breakpoints): Fill this in. * troff/env.c: Allow specification of maximum number of consecutive hyphenated lines. * troff/env.c (environment::is_empty): Add test for !current_tab. Sat Jul 14 11:23:01 1990 James Clark (jjc at yquem) * troff/env.c (environment::hyphenate_line): Don't completely give up if the word is not to be hyphenated; continue so that breaks can be made at break_char_node's. * lib/lib.h: Only define INT_MAX if it's not already defined; undef INT_MIN if it's already defined. * Makefile: Make it easy to define CFRONT_ANSI_BUG. * lib/lib.h: If CFRONT_ANSI_BUG is defined, cast INT_MIN to long. This works around a bug in AT&T C++ 2.0 used with an ANSI C compiler. * macros/tmac.an (an-header): Set no-space mode. * macros/tmac.an (TH): Start a new page if necessary. * Started using ChangeLog at version 0.4.
