In 5928 SECTION_RELEASE_MACRO, if there's not enough space before the next 5929 trap to output the diversion, call T# ourselves, set 5930 SUPPRESS_BOTTOM_REG to 1, spring the trap, then set 5931 SUPPRESS_BOTTOM_REG back to 0. In T#, do nothing if 5932 SUPPRESS_BOTTOM_REG is non-zero. In T#, always mark the current 5933 vertical position and return to it before turning traps on again. 5934 5935Thu Jul 26 02:54:32 1990 James Clark (jjc at yquem) 5936 5937 * troff/node.c, troff/node.h: In classes derived from node, 5938 replace prev_char_width method by last_char_node method. 5939 * troff/env.c (environment::get_prev_char_width): Use 5940 node::last_char_node rather than node::get_prev_char_width. 5941 5942 * Makefile: Added comment about -fno-inline on 68030-based 5943 Apollos. 5944 5945 * troff/reg.c (number_format_to_ascii), eqn/delim.c (DELIM_TABLE_SIZE), 5946 tty/tty.c (tty_font::load_tty_font), dvi/tfmtodit.c (main): Cast 5947 expressions using sizeof to int. 5948 * dvi/dvi.c (dvi_font::handle_x_command): Avoid long->int warnings. 5949 5950 * macros/tmac.e (TS): Don't move @f back past the current 5951 position. 5952 5953Wed Jul 25 09:11:08 1990 James Clark (jjc at yquem) 5954 5955 * ps/ps.c (main): Buffer stderr. 5956 * dvi/dvi.c (main): Likewise. 5957 * tty/tty.c (main): Likewise. 5958 5959 * ps/ps.c (ps_printer::do_import): Improve error handling. 5960 5961 * troff/input.c (abort_request): Use asciify. 5962 5963 * driver/printer.h (printer::draw), driver/printer.c (printer::draw), 5964 ps/ps.c (ps_printer::draw), dvi/dvi.c (dvi_printer::draw): Make 5965 type of first argument int rather than char. This works around a 5966 bug on the 68030 based Apollo using g++ 1.37.1. 5967 5968 * tbl/table.h (class table): Add `keep' member. 5969 * tbl/table.c (table::table): Initialize `keep'. 5970 (table::add_vertical_rule): Set `keep' to 1. 5971 (table::do_top): Only emit table keep macro is `keep' is non-zero. 5972 (table::do_bottom): Likewise for table release macro. 5973 (table::do_row): Emit section keep macro even if the row is 0. 5974 5975Tue Jul 24 08:35:07 1990 James Clark (jjc at yquem) 5976 5977 * macros/tmac.e (@C): Preserve the font family across the change 5978 in environments. 5979 5980Mon Jul 23 10:15:23 1990 James Clark (jjc at yquem) 5981 5982 * lib/font.c: Initialize font::hor and font::vert to 1. 5983 (font::load_desc): Check the values of font::hor and font::vert. 5984 5985 * lib/lib.h: Added definition of INT_DIGITS. Fix it so that it can 5986 be included in a C compilation. 5987 (iftoa): Use INT_DIGITS. Include lib.h. 5988 (itoa): Likewise. 5989 (as_string): Likewise. 5990 * tbl/table.c: Removed definition of INT_DIGITS. 5991 * eqn/box.c (box::top_level): Use INT_DIGITS + 1 instead of 12. 5992 * troff/input.c (input_input_requests): Likewise. 5993 * ps/ps.c (make_encoding_name): Likewise. 5994 (ps_printer::set_style): Likewise. 5995 (ps_output::put_number): Use 1 + INT_DIGITS + 1 instead of 12. 5996 5997 * tty/devascii/R.proto: Map fm onto '. 5998 * tty/devlatin1/R.proto: Likewise. 5999 6000Sat Jul 21 12:45:07 1990 James Clark (jjc at yquem) 6001 6002 * tbl/table.c: Use ' instead of DELIMITER_CHAR in places where the 6003 argument to \w is at a different input level. 6004 6005 * tbl/table.c (table::init_output): Define a new macro 6006 REPEATED_VPT_MACRO, like vpt but if in a diversion also 6007 transparently outputs itself. 6008 (table::define_bottom_macro): Use REPEATED_VPT_MACRO instead of 6009 vpt. 6010 (table::do_row): Likewise. 6011 6012 * tbl/table.c (vertical_rule::print): Prefix the .sp -1 line with 6013 TRANSPARENT_STRING_NAME. 6014 6015 * tbl/table.c (table::init_output): In the table release macro 6016 print an error message and don't produce any output if after 6017 issuing the need request the table still will not fit. Also 6018 remove the diversion after bringing it back. 6019 6020 * tbl/table.c (table::init_output): Define a new macro 6021 REPEATED_MARK_MACRO, like mk but if in a diversion also 6022 transparently outputs itself. 6023 (table::do_row): Mark row_top_reg using REPEATED_MARK_MACRO. This 6024 is necessary because .TH might not call .T#. 6025 (table::do_top): Likewise TOP_REG. 6026 (table::define_bottom_macro): If TOP_REG is no longer valid, use 6027 #T - DOUBLE_LINE_SEP rather than #T. This is necessary because the 6028 table header might contain just the two top rules. 6029 6030Fri Jul 20 10:51:42 1990 James Clark (jjc at yquem) 6031 6032 * troff/div.c: Implement new request `ptr' to print all traps. 6033 6034 * troff/env.c (init_env_requests): Implement `.tabs' reg with 6035 init_string_env_reg. 6036 * troff/env.c (class tab_reg): Deleted. 6037 6038Thu Jul 19 12:07:16 1990 James Clark (jjc at yquem) 6039 6040 * troff/div.c: New number register .pn returns the number of the 6041 next page as set by the pn request. 6042 6043 * macros/tmac.an: Redid headers and footers. Number each manual 6044 entry starting from 1 unless \nC is > 0, like Sun. Added an 6045 optional 5th argument to .TH which specifies the manual name and 6046 appears in the center of the header. Understand the X, P and D 6047 registers like Sun. 6048 6049Wed Jul 18 10:23:31 1990 James Clark (jjc at yquem) 6050 6051 * troff/env.c (init_env_requests): New number register `.lt' to 6052 return the title length. 6053 6054 * troff/node.h (class transparent_dummy_node): New class. 6055 * troff/node.c (class transparent_dummy_node): Provide member 6056 functions. 6057 * troff/env.c (interrupt): Add a transparent_dummy_node, rather 6058 than a dummy_node. 6059 6060 * troff/input.c (token::next): New escape sequence \). 6061 * troff/input.c (get_copy): Recognize \) in copy mode. 6062 6063 * troff/input.c (input_stack::clear): New function. 6064 * troff/input.c (exit_request): Use input_stack::clear. 6065 6066 * troff/token.h: Removed TOKEN_NO_PRINT_CHAR. 6067 * troff/input.c (token::process): Removed case TOKEN_NO_PRINT_CHAR. 6068 6069 * troff/env.c: Move set_page_character to input.c. Move 6070 page_character to input.c also. 6071 * troff/env.c (title): Split off the reading of the parts of the 6072 title into read_title_parts. 6073 * troff/input.c (read_title_parts): New function. Check the 6074 input_level when testing whether a token matches the delimiter. 6075 6076 * troff/input.c (exit_request): New function. 6077 * troff/input.c (init_input_requests): Bind ex request to 6078 exit_request rather than exit_groff. 6079 6080 * troff/input.c (exit_groff): Call tok.next() before 6081 process_input_stack(). 6082 6083Mon Jul 16 09:47:23 1990 James Clark (jjc at yquem) 6084 6085 * troff/env.c: ifdef widow control support on WIDOW_CONTROL. 6086 * troff/env.h: ditto. 6087 * troff/input.c: ditto. 6088 6089 * troff/env.c (environment::is_empty): Test pending_lines. 6090 6091 * troff/env.c (environment::have_pending_lines): Removed. 6092 6093 * troff/input.c: Add request to flush pending lines from the 6094 environment. 6095 6096 * troff/env.c, troff/env.h: Add automatic widow control feature. 6097 6098 * troff/input.c (exit_groff): Do process_input_stack() after 6099 do_break() but before setting exit_flag to 2. 6100 6101 * troff/input.c: Remove FLUSH_PENDING_LINES and 6102 TOKEN_FLUSH_PENDING_LINES. Instead, flush pending lines from 6103 environment after END_TRAP token seen, but only if there aren't 6104 any more traps still unfinished. 6105 * troff/token.h: Remove TOKEN_FLUSH_PENDING_LINES. 6106 6107Sun Jul 15 10:50:08 1990 James Clark (jjc at yquem) 6108 6109 * troff/env.c: Rename the `retain_size' member of class 6110 pending_output_line to `no_fill'. 6111 6112 * troff/env.c (title): When the line is output, make the 6113 retain_size argument !fill. 6114 6115 * troff/node.h: Add `hyphenated' member to struct breakpoint. 6116 * troff/node.c (space_node::get_breakpoints), 6117 (dbreak_node::get_breakpoints): Fill this in. 6118 * troff/env.c: Allow specification of maximum number of 6119 consecutive hyphenated lines. 6120 6121 * troff/env.c (environment::is_empty): Add test for !current_tab. 6122 6123Sat Jul 14 11:23:01 1990 James Clark (jjc at yquem) 6124 6125 * troff/env.c (environment::hyphenate_line): Don't completely give 6126 up if the word is not to be hyphenated; continue so that breaks 6127 can be made at break_char_node's. 6128 6129 * lib/lib.h: Only define INT_MAX if it's not already defined; 6130 undef INT_MIN if it's already defined. 6131 6132 * Makefile: Make it easy to define CFRONT_ANSI_BUG. 6133 6134 * lib/lib.h: If CFRONT_ANSI_BUG is defined, cast INT_MIN to long. 6135 This works around a bug in AT&T C++ 2.0 used with an ANSI C 6136 compiler. 6137 6138 * macros/tmac.an (an-header): Set no-space mode. 6139 6140 * macros/tmac.an (TH): Start a new page if necessary. 6141 6142 * Started using ChangeLog at version 0.4. 6143 6144Local Variables: 6145version-control: never 6146coding: latin-1 6147End: 6148
