2023-08-28 G. Branden Robinson <g.branden.robinson@gmail.com>
* Makefile.am (EXTRA_DIST): Ship ancient groff ChangeLog files
split off from ChangeLog.115 (.old, .111, .112, .113, .114).
2023-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/roff/troff/node.cpp (translate_font): Validate arguments.
2023-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Trivially refactor; add utility function.
* src/roff/troff/node.cpp (is_nonnegative_integer): New function
tests C-style string for validity as such; promoted from open
code because I just spotted a second place we can use it.
2023-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Trivially refactor; demote `int`-returning functions to
Boolean-returning ones and rename.
- check_font -> is_font_name
- check_style -> is_abstract_style
* src/roff/troff/node.h:
* src/roff/troff/node.cpp: Do it.
* src/roff/troff/env.cpp (is_family_valid):
* src/roff/troff/input.cpp (do_if_request): Update call sites.
2023-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/preproc/eqn/main.cpp (main): Trivially refactor; demote
`int` `load_startup_file` to Boolean `want_startup_file`.
2023-08-25 G. Branden Robinson <g.branden.robinson@gmail.com>
[eqn]: Implement "reset" keyword.
* src/preproc/eqn/box.cpp: Use `static` storage class for
parametric defaults, moving them to file scope from global.
Rename `param_table` array of structs to `default_param_table`.
Use the length of this array for iteration since it is known at
compile time. Convert `param_table` to a null pointer.
(set_param): Update diagnostic message text.
(reset_param): New function restores a rendering parameter in
`param_table` to its corresponding value in
`default_param_table`.
(get_param): New function accesses `param_table` entries via a C
string rather than integer lvalues. Use `assert()` to dump
core; this function is never called by the parser, but only by
static logic. Add `fatal()` under this same circumstance, in
case anyone `#define`s `NDEBUG`.
(init_param_table): New function populates the (mutable)
`param_table` from the (immutable) `default_param_table` using
heap storage.
(free_param_table): New function avoids memory leak by freeing
the heap storage allocated for `param_table`.
* src/preproc/eqn/eqn.h: Drop external declaration of `nroff`.
* src/preproc/eqn/eqn.ypp: Add new token `RESET`.
* src/preproc/eqn/lex.cpp: Map C string "reset" to token `RESET`
in untagged struct `token_table`.
(do_reset): Handle new keyword; if argument valid, call
`reset_param()` with it.
(yylex): Hook up token `RESET` to `do_reset()`.
* src/preproc/eqn/box.h: Declare `reset_param()`, `get_param()`,
`init_param_table()`, and `free_param_table()`.
* src/preproc/eqn/main.cpp (main): Call `init_param_table()`
when starting up. Register `free_param_table()` with
`std::atexit()`.
* src/preproc/eqn/pbox.h: Drop external declarations of
rendering parameters.
* src/preproc/eqn/delim.cpp (build_extensible)
(define_extensible_string, delim_box::compute_metrics):
* src/preproc/eqn/lex.cpp (yylex):
* src/preproc/eqn/limit.cpp (limit_box::compute_metrics):

(matrix_box::compute_metrics, matrix_box::output):
* src/preproc/eqn/script.cpp (script_box::compute_metrics):
* src/preproc/eqn/sqrt.cpp (sqrt_box::compute_metrics): Migrate
from lvalue access to `get_param()` for parameter retrieval.
* src/preproc/eqn/eqn.1.man (Customization): Document it.
* src/preproc/eqn/tests/parameters-can-be-set-and-reset.sh: Test
it.
* src/preproc/eqn/eqn.am (eqn_TESTS): Run test.
* NEWS: Add item.
Fixes <https://savannah.gnu.org/bugs/?62692>.
2023-08-24 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/preproc/eqn/box.cpp (set_param): Migrate iteration style
to use new `array_size()` instead of null pointer guards at the
end of an array of structs.
2023-08-24 G. Branden Robinson <g.branden.robinson@gmail.com>
[src]: Add template function for obtaining the length of an
array.
* src/include/lib.h (array_size) [__cplusplus]: Do it.
2023-08-22 Dave Kemper <saint.snit@gmail.com>
* doc/pic.ms: Document `PY` macro, new to groff 1.23.0.
Fixes <https://savannah.gnu.org/bugs/?64575>.
2023-08-22 Dave Kemper <saint.snit@gmail.com>
* tmac/pic.tmac (PY): Call `PF` rather than duplicating its
{three bytes of} code. This is almost too trivial to DRY, but
{1} the new form is a cue to the human reader that .PY is meant
to be an alias of .PF; and {2} .PE was already defined as a
variant of .PF with an explicit call to it, so this makes the
.PY definition conform to that precedent.
2023-08-22 G. Branden Robinson <g.branden.robinson@gmail.com>
* tmac/an.tmac: Stop setting `an*can-hyperlink` if formatting
for PDF; we don't yet have support for this implemented, leading
to vanishing text when the `U` register is true and, for
instance, `UR`/`UE` are called with no link text.
Fixes <https://savannah.gnu.org/bugs/?64572>.
2023-08-21 G. Branden Robinson <g.branden.robinson@gmail.com>
* doc/doc.am (PROCESSEDFILES_DEPS_HTML): Depend on
tmac/html{,-end}.tmac.
(PROCESSEDFILES_DEPS_PDF): Depend on tmac/pdf.tmac.
(PROCESSEDFILES_DEPS_PS): Depend on tmac/ps.tmac.
(PROCESSEDFILES_DEPS_TXT): Depend on tmac/tty.tmac.
2023-08-21 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/devices/grops/ps.cpp (ps_printer::define_encoding):
* src/devices/grops/psrm.cpp (resource_manager::output_prolog)
(resource_manager::supply_resource): Report more intelligible
diagnostics when libgroff's `font::open_file()` returns a null
pointer without setting `errno`. The only way this can happen
is if it rejected the file name for containing a slash, thus
attempting directory traversal (recall Savannah #61424). Also
fix code style nits: explicitly `#include` errno.h C standard
library header, align style of null pointer checks, and stop
explicitly setting `errno` to zero before (indirectly) calling
`fopen()`; we inspect `errno`'s value only under a documented
error condition (a null stream pointer). See errno(3).
* NEWS: Add item; we should have mentioned this (and produced
these better diagnostics) when 1.23.0 was released.
Distributors may find this change desirable to backport.
Fixes <https://savannah.gnu.org/bugs/?64577>. Thanks to Phil
Chadwick for the report and Deri James for swiftly finding a
correct workaround that suited the reporter.
2023-08-19 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/roff/troff/node.cpp (class tfont_spec): Stop declaring
copy constructor. The implicitly defined one suffices.
Resolves "-Wdeprecated-copy" warning from GCC.
Fixes <https://savannah.gnu.org/bugs/?57515>. Thanks to Bjarni
Ingi Gislason for the report.
2023-08-16 G. Branden Robinson <g.branden.robinson@gmail.com>
* configure.ac: Include paper format in configuration report.
* m4/groff.m4 (GROFF_PAGE): Slightly refactor, and help users to
figure out how the "configure" script decided upon the paper
format it did by supplementing the `AC_MSG_RESULT` message. If
not falling back to the "letter" default or honoring a
command-line setting (e.g., "./configure PAGE=a4"), report which
file or command was used to infer the paper locale. Apply DRY
principle by using shell variables more.
Prompted by discussion with Damian McGuckin on the groff list.

2023-08-12 G. Branden Robinson <g.branden.robinson@gmail.com>
Our "Makefile.am" defines an `RM` macro if make(1) itself does
not, and our Automake files employ it extensively; sweep up the
stragglers.
* font/devpdf/devpdf.am (mostlyclean_devpdf_extra)
(uninstall_devpdf):
* src/devices/xditview/xditview.am (uninstall_xditview):
* src/libs/libgroff/libgroff.am (install_charset_data):

(uninstall_indxbib): Do it.
2023-08-12 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/utils/indxbib/indxbib.am (install_indxbib): Use `$(LN_S)`,
not `ln -s`.
2023-08-11 G. Branden Robinson <g.branden.robinson@gmail.com>
[eqn]: Trivially refactor.
* src/preproc/eqn/main.cpp (input_char_description): Migrate to
`const`-qualified object to size an array of length computed at
compile time and avoid repeating lengthy expression.
2023-08-10 G. Branden Robinson <g.branden.robinson@gmail.com>
[man]: Add new `TS` register to configure required separation
between a (`IP`, `TP`) paragraph's tag and its body, and change
the default amount used for this purpose from 1n to 2n. Retire
private register `an-tag-separation` in favor of `TS`.
* tmac/an.tmac: Assign `TS` value of 2n if not already defined.
(TH): Stop setting the default here.
(an-write-paragraph-tag): Use it.
Fixes <https://savannah.gnu.org/bugs/?64539>. Thanks to Alex
Colomar for the report.
2023-08-09 G. Branden Robinson <g.branden.robinson@gmail.com>
[man,mdoc]: Change base paragraph indentation to 5n. This
corresponds to the amount used by historical man(7) and mdoc(7)
implementations going back to Unix Version 7 and 4.3BSD-Reno,
respectively.
* tmac/an.tmac: Introduce new interface register, `BP`, to
control the base paragraph indentation amount. Formerly, `IN`
determined it, the default relative inset amount, and the
default amount of additional indentation used by `IP`, `TP`, and
the deprecated `HP`.
(an-reset-margin-and-inset-level, SH, SS): Use it.
* tmac/doc.tmac: Introduce `BP` register, replacing `IN`.
* tmac/mdoc/doc-common (Sh): Use it.

Fixes <https://savannah.gnu.org/bugs/?64018>. Thanks to
Thorsten Glaser and Ingo Schwarze for the discussion.
2023-08-05 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Add paranoia to `token::description()`.
* src/roff/troff/input.cpp (token::description): Clear static
buffer on entry to function to avoid another problem like
Savannah #62813.
2023-08-05 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Trivially refactor (`define_color`).
* src/roff/troff/input.cpp (define_color): Throw more helpful
diagnostics when arguments from this 3-5-argument-taking request
is not given enough of them. Rename internal variable `style`
to `color_space` to make it less opaque.
2023-08-05 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Trivially refactor.
* src/roff/troff/input.cpp (input_char_description): Migrate to
`const`-qualified object to size an array of length computed at
compile time and avoid repeating lengthy expression.
2023-08-04 G. Branden Robinson <g.branden.robinson@gmail.com>
* man/groff_diff.7.man: Drop displayed examples. Man pages'
honor as references, not tutorials, has been vigorously
championed on the groff mailing list. Accordingly, drop
displayed examples from this page; all are available in groff's
Texinfo manual.
* NEWS: Add item in case people wonder where they've gone.
2023-08-04 G. Branden Robinson <g.branden.robinson@gmail.com>
[tbl]: Fix staggering of text block entries.
* src/preproc/tbl/table.cpp: Add C preprocessor macro storing a
"text block staggering macro" name.
(block_entry::position_vertically): Call it in generated output
with a negative half-vee motion.
(block_entry::position_vertically, left_block_entry::print)
(right_block_entry::print, center_block_entry::print)
(alphabetic_block_entry::print): Call it in generated output
with a positive half-vee motion.
(table::init_output): Write out its definition in generated
output. It wraps the `sp` request. If we're in a diversion,
use the `\!` technique to recursively call ourselves and bubble
up the spacing request a diversion level (spacing requests of
anything other than 1v are ignored in diversions). Otherwise,
invoke the request.
Fixes <https://savannah.gnu.org/bugs/?64454> a.k.a. Debian
#1038391. Thanks to наб for the report and a good test case.
2023-08-04 G. Branden Robinson <g.branden.robinson@gmail.com>
[tbl]: Regression-test Debian #1038391.
* src/preproc/tbl/tests/\
align-staggered-text-blocks-correctly.sh: Do it.
* src/preproc/tbl/tbl.am (tbl_TESTS): Run test.
2023-08-04 G. Branden Robinson <g.branden.robinson@gmail.com>
[man]: Deprecate `SB` macro. It is a SunOS 4.0 (1988) extension
that in most contexts, does nothing you can't achieve with `SM`
and `B` together (in either order).
Study of the SunOS 4 man page corpus suggests a reason for its
introduction of this macro: use of `SB` immediately after `TP`
was common (610 out of 2,111 occurrences). The problem with
`TP` and the mechanism suggested above is that input traps in
troff normally ignore the `\c` escape sequence, the use of which
would be necessary to get the desired effect. In groff since
1.22.4, the man(7) `TP` macro uses GNU troff's `itc` request,
which _does_ respect `\c`. (mandoc(1) 1.14.2 and later behave
compatibly with groff man >= 1.22.4.) Solaris 11 switched to
groff as its troff implementation, so there is no reason for
newly written or currently maintained man pages to employ `SB`.
* tmac/an.tmac (SB): Throw deprecation warning.
* tmac/groff_man.7.man.in (Description): Move macro from table
to deprecation list.
(Font style macros): Move description from here...
(Deprecated features): ...to here.
(Portability): Drop mention, since we don't encourage people to
use it at all.
Fixes <https://savannah.gnu.org/bugs/?64515>.
2023-08-03 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/roff/troff/node.cpp (zoom_font): Validate arguments more.
Invalid inputs could have bizarre consequences.
Fixes <https://savannah.gnu.org/bugs/?64505>.
2023-08-02 G. Branden Robinson <g.branden.robinson@gmail.com>
Drop tmac/fixmacros.sed. We hadn't ever actually installed it;
it was provided only in our distribution archives, as far back
as our history indicates.
* tmac/fixmacros.sed: Delete.
* tmac/tmac.am (EXTRA_DIST): Stop shipping it.
* PROBLEMS: Recast and update relevant item description. This
is the only place the file was documented.
2023-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
* tmac/doc.tmac (doc-parse-args): Set ellipses in roman.
Thanks to Lennart Jablonka for reminding me of this issue on the
linux-man mailing list.
2023-07-29 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/libs/libgroff/fontfile.cpp: Update `#include`s.
(font::open_file): Do more parameter validation. Don't
construct a file name for opening from components that are null
pointers. Also `assert()` this since it should be an invariant.
Migrate from `sprintf()` to `snprintf()`; we have the size of
the destination buffer handy.
Fixes <https://savannah.gnu.org/bugs/?64485>. Thanks to Bjarni
Ingi Gislason for the report.
2023-07-29 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/preproc/pic/troff.cpp (troff_output::set_location): Do
more parameter validation. Generate the two-argument form of
the `lf` request only if the C string holding the new file name
to write isn't a null pointer. Also `assert()` this since it
should be an invariant.
Fixes <https://savannah.gnu.org/bugs/?64488>. Thanks to Bjarni
Ingi Gislason for the report.
2023-07-28 G. Branden Robinson <g.branden.robinson@gmail.com>
[gxditview]: Add accelerators for "Print" action.
An apparent bug in a support library affects some users; it
disables gxditview's pop-up menu. (The menu pops up, but no
item can be selected.) Also, "Print" was the only action for
which no keyboard accelerator was defined. "p" (unmodified) is
already bound to `PreviousPage()`; bind "p" with any of the
modifiers Shift, Ctrl, Alt, or Meta to `Print()`.
* src/devices/xditview/GXditview.ad: Do it.
* src/devices/xditview/gxditview.1.man: Document it.
2023-07-28 G. Branden Robinson <g.branden.robinson@gmail.com>
* tmac/es.tmac: Scream the entire word "BIBLIOGRAPHÍA", instead
of dying off to a murmur at the last two letters.
2023-07-26 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Add new `.trap` built-in register.
* src/roff/troff/div.h (class diversion, class macro_diversion,
class top_level_diversion): Declare new member function
`get_next_trap_name`.
* src/roff/troff/div.cpp (macro_diversion::get_next_trap_name):
New member function returns name of diversion trap if any, and
if its position is greater than the vertical drawing position,
otherwise an empty string.
(top_level_diversion::get_next_trap_name): New member function
returns the name of the next vertical position trap, if any,
otherwise an empty string.
(class next_trap_name_reg): New class has one member, a
`get_string()` function.
(next_trap_name_reg::get_string): New function.
(init_div_requests): Add `.trap` to the register dictionary and
wire it up to `next_trap_name_reg`.
* doc/groff.texi (Page Location Traps):
* man/groff.7.man (Read-only registers):
* man/groff_diff.7.man (New registers): Document it.
* src/roff/groff/tests/dot-trap_register_works.sh: Test it.
* src/roff/groff/groff.am (groff_TESTS): Run test.
* NEWS: Add item.
Fixes <https://savannah.gnu.org/bugs/?64212>. Thanks to Dave
Kemper for feedback.
2023-07-21 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/roff/troff/node.cpp (unbreakable_space_node::tprint):
Write word marker ('w' command) to output.
* NEWS: Add item.
Fixes <https://savannah.gnu.org/bugs/?64356>.
2023-07-21 G. Branden Robinson <g.branden.robinson@gmail.com>
* tmac/papersize.tmac: Set register `#R_MARGIN` for mom(7)'s
benefit, not `R_MARGIN`, which it neither tests nor interpolates
as a register. Continues commit bed42a77cb, 2022-11-16.
2023-07-21 G. Branden Robinson <g.branden.robinson@gmail.com>
* tmac/papersize.tmac: If the `paper` string is defined when
this macro file is loaded, set the `O` (mm page offset register)
independently of the `W` (mm line length ["width"] register).
2023-07-21 G. Branden Robinson <g.branden.robinson@gmail.com>
[docs]: Revise material in our Texinfo manual.
* doc/groff.texi (Manipulating Filling and Adjustment): Document
a CSTR #54 erratum; the arguments to the `ss` request are in
12ths of the selected font's `spacewidth` parameter, not 36ths
of an em. Drop false claim of rounding of `.ss` and `.sss`
register values on terminal devices. (Rounding of any resulting
adjustment quantities might still occur, but this is part of the
usual application of motion quanta and not particular to the
`ss` request.) Characterize "undiscardable space" as
"horizontal motion" to help the reader acquire this essential
distinction between horizontal spaces and motions.
(Manipulating Spacing): Clarify behavior. Distinguish `sp`
request from `\v` escape sequence and cross reference the
latter. Recast to squeeze presentation of `ss` request onto one
U.S. letter page when typeset. Drop (commented-out) trivial
example of `ls` usage in favor of new example illustrating some
macros using `vs` instead, for pedagogical purposes and to eat
up a lot of dead space on the page caused by a later lengthy
example. (Knuth-Plass for the...uh...win.)
(Page Control): Stop (arguably) mis-applying the term "widow",
in favor of less metaphorical language. Extend Woolf example to
narrow the seas of vertical space produced by TeX's formatting
of the page it occupies. (Our blanched discourse can use the
purple prose.)
(Page Motion): Fix straggling use of "escape" as a noun; we
prefer "escape sequence".
* man/groff.7.man (Request short reference) <ss>: Sync.
Fixes <https://savannah.gnu.org/bugs/?64440>. Thanks to Dave
Kemper for the report and review.
2023-07-25 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/roff/troff/env.cpp (environment::print_env): Fix error in
report. The units of {minimum inter-word, additional
inter-sentence} space size are 12ths of the font's "spacewidth"
parameter, not 36ths of an em.
Consider the following input.
.\" groff -T ps -Z
.nf
foo bar1
.ss 12
foo bar2 \" cases 1 and 2 are the same
foo\h'1m/3u'bar3 \" wider than 1 & 2
foo\h'1m/36u*12u'bar4 \" slightly narrower than case 3
.ss 11
foo bar5 \" narrower than case 1 (as expected)
foo\h'1m/36u*11u'bar6 \" between cases (1,2) and 4
2023-07-19 G. Branden Robinson <g.branden.robinson@gmail.com>
* tmac/papersize.tmac: If not already defined, set `PO` register
to one inch to integrate with ms(7), man(7), and mdoc(7).
2023-07-18 G. Branden Robinson <g.branden.robinson@gmail.com>
[ms]: Improve documentation of pic(1) usage.
* tmac/groff_ms.7.man
(Tables, figures, equations, and references): Document the
mandatory arguments to `PS`. Explain that pic(1) will supply
them. (This is documentation of the _package's_ interface.)
* doc/groff.texi: As above, and add example of pic(1) input.
Also tighten wording.
* doc/ms.ms: As above, and supply pic output corresponding to
example (if typesetting). Add a keep.
* doc/doc.am (doc/ms.ps): Preprocess with pic; call groff with
`-p` option when generating document.
* src/utils/grog/tests/smoke-test.sh: Drop a test case; we no
longer have an ms(7) document in the tree that uses tbl and eqn
but not pic.
2023-07-17 G. Branden Robinson <g.branden.robinson@gmail.com>
[tbl]: Fix post-1.23.0 regression.
* src/preproc/tbl/main.cpp (process_format): Fix thinkos
introduced in commit ba420961c3, 19 May, which caused the first
character after [PpVv] column modifiers to be ignored. Problem
visible in typeset renderings of our "ms.ms" document, where
some table entries were getting rendered at a type size of 1p.
2023-07-17 G. Branden Robinson <g.branden.robinson@gmail.com>
[ms]: Fix Savannah #64438.
* tmac/s.tmac (@PS): Stop treating excess arguments as
erroneous, foregoing preparation for pic(1) output. Fixes
regression from groff 1.22.4.
Fixes <https://savannah.gnu.org/bugs/?64438>. Thanks to Doug

* m4/groff.m4 (GROFF_PROG_YACC): Behave more like `AC_PROG_YACC`
where useful, seeking "bison" first. Drop comment claiming that
"Bison-generated parsers have problems with C++ compilers other
than g++", which dates back to groff 1.10, 26 November 1995.
Let us optimistically assume that GNU Bison (and C++ compilers)
have improved since then.
2023-07-16 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/roff/groff/groff.cpp (main): Update copyright notice and
warranty disclaimer. Bump year. Lead with declaration as free
software (join us now); specify GPL version and user's option to
upgrade to later version. Use a warranty disclaimer inspired by
GNU Bison. Drop mention of "COPYING" file, which is not
installed by groff's "install" make(1) target and not sufficient
information to aid users of groff packages prepared by
distributors (which neverless are legally bound to provide
licensing information via some means, and do so with high
reliability). After almost 35 years, we can have some hope that
people have heard of the GNU GPL and can locate a copy of it
without great difficulty. Also drop use of term "subprogram".

* src/preproc/html/pushback.cpp (pushBackBuffer::isString):
Partially revert commit 411b42f4ec, 2 June. This member
function needs a signed type to iterate backwards for internal
validation purposes, so use `ptrdiff_t` instead of `size_t`.
Fixes post-1.23.0 problem with pre-grohtml infinitely looping on
complex documents like groff_char(7). Mea culpa.

Slightly refactor.
[grodvi, grops, xditview, libbib, libgroff, eqn, pre-grohtml,
preconv, refer, troff, tfmtodit]: Store return value of

If invalid, throw diagnostic and ignore `fam` request.
* src/roff/troff/env.h (is_family_valid): Declare; make visible.
* src/roff/troff/input.cpp (main): Call `is_family_valid()` on

[tbl]: Refactor handling of type size and vertical spacing.
* src/preproc/tbl/table.h (struct inc_number): Rename this...

types. The `inc` `short` becomes a `relativity` enum
because it only ever takes 3 values. The `val` short becomes an
`int`, undoing what I suspect to be premature optimization.

2023-05-19 G. Branden Robinson <g.branden.robinson@gmail.com>
* src/preproc/tbl/main.cpp (process_format): Accept (and

descriptor, as is already done for [fFmMwW]. Modify [wW] to use
the same loop style as the others, for consistency.

2023-05-19 G. Branden Robinson <g.branden.robinson@gmail.com>
[eqn]: Implement tunable "half_space" and "full_space"
parameters. They default to the same widths as "thin_space" and
"thick_space", respectively, but control the widths of the '^'
and '~' input tokens.
* src/preproc/eqn/box.cpp: Add globals `half_space`,
`full_space`.
(struct S): Recognize "half_space" and "full_space" as
parameters to the "set" primitive, and map them to the globals.
(half_space_box::output): Format the half space width.
(full_space_box::output): Format the full space width.
(full_space_box::output, thick_space_box::output): Drop
workaround for Firefox 1.5 MathML bug (November 2005). Emit
"&ThickSpace;" entity instead of "&ensp;".
* src/preproc/eqn/eqn.1.man (Customization): Document feature.

[troff]: Fix Savannah #64166.
* src/roff/troff/node.cpp (bold_font): Add `WARN_MISSING`
diagnostic if request given no arguments; it does nothing, and
the behavior of this request is sufficiently complex that it's
worth saying so. Stop throwing font lookup error if second
argument cannot be resolved as a font name; it might be an
emboldening amount instead.

[troff]: Fix Savannah #64104.
* src/roff/troff/input.cpp (set_escape_char): Rename this...

character to be set to the same thing as the control or no-break
control characters.
* doc/groff.texi (Using Escape Sequences): Document
restrictions.
* src/roff/troff/env.h (class environment): Slightly refactor.
Rename fields `control_char` and `no_break_control_char` to
`control_character` and `no_break_control_character`,
respectively, and make them private. Add public getters and
setters for them.
(get_control_character): New public member function returns
`unsigned char`.
(set_control_character): New public member function takes an
`unsigned char` and returns a `bool`.
(get_no_break_control_character):
(set_no_break_control_character): Similar.
* src/roff/troff/env.cpp (environment::environment): Update
constructors to use new field names and initialize them in their
new order of declaration.
(environment::copy): Similar. (Not to be confused with a copy
constructor, this member function implements the operation of a
valid `evc` GNU troff request.)

* src/roff/troff/input.cpp: Resurrect handling of `cc` and `c2`
requests here, with more error handling.
(assign_escape_character, process_input_stack): Use the new
getters defined above in environment object since the relevant
fields are now private.
(assign_control_character): New function assumes the former
responsibilities of env.cpp:control_char and rejects the request
if the desired character is already the escape or no-break
control character.
(assign_no_break_control_character): New function assumes the
former responsibilities of env.cpp:no_break_control_char and
rejects the request if the desired character is already the
escape or control character.
(process_input_stack): Reorder comparisons to avoid inadvertent
lvalue assignment. Add parentheses to assignment with complex
RHS.
(init_input_requests): Attach `cc` and `c2` requests to new
functions above.
* doc/groff.texi (Control Characters): Document restrictions.
2023-05-07 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Don't quote a character with itself in diagnostics.

2023-05-06 G. Branden Robinson <g.branden.robinson@gmail.com>
[troff]: Revise output warning diagnostic format.
* src/roff/troff/input.cpp (do_error): For the `OUTPUT_WARNING`
value of the `error_type` enum, spell out the words "page" and
"diversion" instead of abbreviating them, and place the
diversion information (if present) in parentheses.

[troff]: Drop `POPEN_MISSING` preprocessor macro.
3 source files test this macro but nothing appears to define it.
It dates back to (at least) 1994. I suspect this of being
bitrot. Reasons include: (1) We test for a declaration of
`popen` in our "configure.ac" file; (2) our gxditview command
uses `popen` _without_ #ifdef-guarding it (perhaps the
assumption was that any system that supported X11 also had a
working `popen`); (3) our "nonposix.h" header file defines a
macro aliasing `popen` to `_popen`, which is its typical name on
Windows systems, and is the most likely build host candidate for
which support might have been missing as late as 1994.
Microsoft end-of-lifed MS-DOS in 2000. If someone wants to

[man]: Preserve user-selected font family.
* tmac/an.tmac: When initializing, save the currently selected
font family as `an*body-family` instead of forcing 'T' (Times,
which is the formatter's default, even on nroff-mode devices
that can't switch families). This change makes the formatter's
`-f` option work on man(7) documents again (important for
Japanese man pages, but there is now once again nothing stopping
you from viewing man pages in Palatino or Helvetica on the 'ps'
and 'pdf' devices where these families are available). It also
reopens an avenue for rogue pages to affect the rendering of
unrelated documents later in batch rendering, but there are many
other, and worse, ways for rogue pages to do damage. Problem
introduced by me in commit e0e16d8e65, 15 March 2022.

* tmac/pdfpic.tmac: Refactor to make comprehensible some
woefully undocumented cleverness and improve efficiency.
(PDFPIC): Break out flaming-hoop-leaping "clever" bit of `sy`
usage into its own macro, calling from here and relocating its
requests from here...
(pdfpic@get-image-dimensions): ...to here. When using `sy`
request to collect and munge output of pdfinfo(1), (a) disable
the escape character while defining the macro; (b) construct the
command in a roff string, appending to it in discrete, hopefully
comprehensible chunks; (c) disable the escape character during
macro interpretation wherever possible (most of it); (d) retain
doubled backslashes so that they survive subsequent string
interpolation; (e) stop using grep(1) in the pipeline when
sed(1) is perfectly capable of performing its own input
filtering; (f) invoke sed with '-n' option and emit output only
upon a successful substitution; (g) replace unportable(!) POSIX
BRE character class '[:digit:]' in substitution match text with
'[0-9]'; and most importantly (h) replace multi-line sed 's'
replacement text (see below for the reason we can't use it) with
single roff control line employing the groff extension escape
sequence `\R` to assign multiple registers. Annotate
portability and escaping challenges. Tested on GNU/Linux, macOS
12, and (with simulated pdfinfo(1) output) Solaris 11.
There is a problem with trying to embed true newlines into the
arguments of a `sy` request. The C++ function that GNU troff
uses to assemble the command string (character by character)
_does not recognize C/C++ string literal escape sequences_.
This means that you _cannot_ embed "\n" in `sy`'s arguments and
have it survive, as a newline character, into the command string
passed to the standard C library's system(3) function. ("A\nB"
gets encoded as 'A', '\\', 'n', 'B', not 'A', '\n', 'B'.)
Unfortunately, this appears to be AT&T troff-compatible
behavior. But it means that you _cannot_ portably construct
multi-line replacement text for sed's 's' command. (Other sed
commands like 'a', 'c', and 'i' will be similarly affected.)

* doc/doc.am (install-txt): Look for "groff.txt" in the source
and build directories in sequence; it could be in either place
depending on whether the build is from the Git repository or
from a distribution archive. Annotate this. Fixes
"install-doc" target when building from Git repository. Problem
introduced by me in commit 691fc70108, 22 February. Thanks to
Nikita Ivanov for the report.
(install-pdf-local, install-html-local): Similar.
Also fixes <https://savannah.gnu.org/bugs/?64059>, later
reported anonymously.

* doc/doc.am (maintainer-clean-local): Remove temporary "*.t2d"
and "*.t2p" directories created by texi2dvi.

[build]: Fix gxditview linking on AIX.
* m4/groff.m4 (GROFF_X11): Add macro dependency on
`AC_CANONICAL_HOST`. Introduce new variable `X_AW_DEPS`, empty
on most hosts. If we otherwise have Athena widget library
support, and the host is AIX, force linkage against Xpm and Xext
libraries to reflect modern Athena dependencies, which AIX's
linker doesn't figure out on its own. `AC_SUBST` this variable,
exposing it to Automake files.
* src/devices/xditview/xditview.am (gxditview_LDADD): Use it.
{A similar change might also be useful for HP-UX, another Unix
System V descendant; see
<http://hpux.connect.org.uk/hppd/cgi-bin/wwwtar?/hpux/Gnu/\
groff-1.23.0/groff-1.23.0-src-11.31.tar.gz+groff-1.23.0/\
HPUX.Install+text>. --GBR, 2023-07-10}
2023-04-20 G. Branden Robinson <g.branden.robinson@gmail.com>
* bootstrap.conf (gnulib_modules): Add "sys_wait" module. MinGW
does not provide "sys/wait.h", which we require in
src/preproc/html/pre-html.cpp since commit 11137209ed, 27 June.
2023-04-20 G. Branden Robinson <g.branden.robinson@gmail.com>
* Makefile.am: Initialize (as empty) Automake variables that we
don't use but which gnulib modules expect to be defined.
(AUTOMAKE_OPTIONS, SUBDIRS, noinst_HEADERS, noinst_LTLIBRARIES)
(pkgdata_DATA, MOSTLYCLEANDIRS, AM_CFLAGS): Do it.
Thanks to Bruno Haible for the advice.

[mdoc]: Regression-test Savannah #57665, but for mdoc.
* tmac/tests/doc_TS-do-not-keep-tables-when-cR-set.sh: Do it.
* tmac/tmac.am (tmac_TESTS): Run test.
Fixes <https://savannah.gnu.org/bugs/?64037>.
