* [man pages]: Revise some syntax synopses.G. Branden Robinson2023-05-061-1/+1
| | | | | | | | | | | | | Use ellipsis more idiomatically, favoring it over plurals, and including it within instead of outside option brackets for clarity. The construction: foo bar [baz] ... is ambiguous. If I specify no "baz", can "bar"s be repeated? Also say "argument" when we mean an option OR an operand.
* gropdf(1): Add "Macros" subsection with `pdfinfo`.G. Branden Robinson2023-05-061-0/+32

* gropdf(1): Fix more content/style/markup nits.G. Branden Robinson2023-05-061-38/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Content: * More carefully distinguish escape sequences from device control commands; the former are more general. * The *roff `\X` escape sequence is a device control command, not a "special". *roff already freights the latter term with enough meaning without hauling in TeX's use for it. * The "ps:" or "pdf:" part of a device control command escape sequence parameter is the "tag", not the entire parameter. It is a name spacing convention. * Clarify operation of `xrev` device control command. Style: * Recast: all device control commands are "extensions"; there is no standard set. * Convert mentions of (g)pic(1) and grops(1) to man page cross references. * Set pic(1) command names in bold, not italics. * Set "mom" macro package name in italics, not bold. * Set "gropdf" in italics, not bold. * Capitalize "PDF" in prose. * Protect Perl's "localtime" function name from hyphenation. * Hyphenate adjectival phrases. * Hyphenate metasyntactic variable consistently with its introduction. * Otherwise recast for (attempted) clarity and concision. Markup: * Use two empty requests where vertical space is expected. * Annotate a mismatch in conventions between grotty(1) and gropdf(1).
* gropdf(1): Fix content, style, and markup nits.G. Branden Robinson2023-05-051-38/+65
| | | | | | | | | | | | | | | | | | | | | | | Content: * Introduce the concept of convenience macros earlier, then rely on it. * Align terminology regarding page location traps with the rest of groff's documentation. * Align header/footer terminology with the rest of groff's documentation. Style: * Tighten wording. * Set macro call literals in bold. * Use imperative voice more when describing device control commands. * Present convenience macros _after_ full discussion of device control command behavior, not in the midst of it. * Coalesce some single-sentence paragraphs into their predecessors. Markup: * Set file names in italics. * Protect macro call literals from hyphenation. * Use an empty request between sentences. * Use two empty requests where vertical space is expected.
* gropdf(1): Add gpresent link and description.G. Branden Robinson2023-05-051-0/+13
| | | | | The page references it several times; we should explain what it is and link to it.
* gropdf(1): Fix pagination nit.G. Branden Robinson2023-05-051-2/+0
| | | | | Drop a paragraph break after a very short paragraph to buy a vee and fix an orphaned line on U.S. letter paper.
* gropdf(1), pdfmom(1): Update authorship credits.G. Branden Robinson2023-05-052-1/+13
|
* [man pages]: Adjust dead-tree pagination.G. Branden Robinson2023-05-052-0/+4
| | | | Also drop an unnecessary paragraph break in glilypond(1).
* groff(1): Tighten wording.G. Branden Robinson2023-05-051-3/+1
|
* groff(1), troff(1): Document operand handling.G. Branden Robinson2023-05-042-1/+23
|
* src/roff/troff/TODO: Remove implemented item.G. Branden Robinson2023-04-251-2/+0
| | | | Implemented in commit 41d05cbfac, 4 July 2019.
* tbl(1): Fix style nits.G. Branden Robinson2023-04-201-22/+32
| | | | | | | | | | | | | | * Kick mention of region option case-invariance down to "GNU tbl enhancements" subsection. * Discuss the content of column descriptors _before_ discussing how they're separated. * Arrange mentions of column modifier correspondence to *roff requests consistently, _after_ covering the syntax of those modifiers. * Clarify that tbl doesn't perform measurements itself; it constructs formatter instructions to do so. * Tighten wording. Also adjust dead-tree pagination.
* eqn(1): Fix style and content nits.G. Branden Robinson2023-04-141-2/+2
| | | | | Align language with forthcoming (post-1.23.0) changes from Savannah ticket #63967.
* eqn(1): Revise discussion of font primitives.G. Branden Robinson2023-04-141-63/+52
| | | | Thanks to Doug McIlroy and Ralph Corderoy for the feedback.
* eqn(1): Fix missing comma.G. Branden Robinson2023-04-091-1/+2
|
* eqn(1): Clarify new primitives.G. Branden Robinson2023-04-091-0/+10
| | | | The list below this subsection title isn't comprehensive.
* gropdf(1): Document "--help" option.G. Branden Robinson2023-04-091-1/+9
|
* NEWS, pic(1): Clarify and tighten wording.G. Branden Robinson2023-04-011-1/+3
|
* pic(1), tbl(1): Parallelize wording with eqn(1).G. Branden Robinson2023-04-012-7/+6
| | | | | | | | | This tightens pic(1)'s claim regarding what can accept its output; it no longer implies that any troff can interpret it. The output does seem to largely avoid groff-specific syntax or extensions, apart from stroke and fill color selection. It's not clear to me if that defeats the processing of GNU pic output by, say, DWB or Plan 9 troff, so until we know, make the narrower claim.
* pic(1): Protect keywords from hyphenation.G. Branden Robinson2023-04-011-5/+5
|
* afmtodit(1): Document "--help" option.G. Branden Robinson2023-04-011-1/+10

* eqn(1): Hyphen-protect macro, primitive names.G. Branden Robinson2023-04-011-29/+29
| | | | Also drop needless quotation of a lone macro argument.
* tbl(1): Clarify 'w' and 'z' modifier behavior.G. Branden Robinson2023-04-011-7/+7

* Revert "Make pdfmom more versatile."G. Branden Robinson2023-03-202-45/+5
| | | | | | | | | | This reverts commit 0290924f05f823039c546f5b14422af7eef70644. This has been separately committed on the post-1.23.0 branch so that it is easier for Bertrand to decide where to place a tag for 1.23.0.rc4 in this branch, or which commits to cherry-pick from that branch before doing so. (It is not yet decided what commits since 1.23.0.rc3 from this branch of post-1.23.0 will comprise 1.23.0.rc4--possibly all.)
* Make pdfmom more versatile.Deri James2023-03-092-5/+45
| | | | | | | * src/devices/gropdf/pdfmom.pl: Add flag -roff which severs hardcoded link to the mom macros. * src/devices/gropdf/pdfmom.pl: Document changes.
* Use a better type for symbol hashes.G. Branden Robinson2023-03-061-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bootstrap.conf: Add "stdint" module to ensure that the `uintptr_t` type is available. * src/include/symbol.h: Include <stdint.h> for `uintptr_t`. (class symbol): (symbol::hash): Change return type from `unsigned long`, which causes build failures on 64-bit MinGW, to `uintptr_t`. (symbol::hash): Use a C++ type cast, not a C-style one. Thanks to Bruno Haible for reporting the build failure in the 64-bit MinGW environment, and for suggesting a remedy. Also update editor aid comments; drop old style Emacs file-local variable setting. Any day you get to use the foot-Howitzer reinterpret_cast is a good one. Commits since 0221b657fe tested on: Debian bullseye Debian sid 2023-03-06 chroot macOS 12 OpenBSD 7.2 Solaris 10 Solaris 11
* [groff]: Revise a test to be more revealing.G. Branden Robinson2023-03-061-9/+26
| | | | | | | | | | | | | | | | | | | * src/roff/groff/tests/initialization_is_quiet.sh: Stop using "set -e". Instead use `fail` variable and `wail` function (and lowercase names for our internal variables) like many of our other tests. If the "unset" shell built-in fails, skip the test (prompted by /usr/xpg4/bin/sh on Solaris). Attempt every groff locale, with and without compatibility mode initially enabled, instead of stopping at the first failure. Report standard error and standard output content separately. Use groff's `-a` flag to prepare the standard output, for readability. * PROBLEMS: Document that this test might be skipped rather than failing on Solaris. (What actually happens depends on which shell you run it with, and we advise a variety of approaches.) Thanks to Bruno Haible for feedback regarding mysterious failures of this test on GNU/Hurd and NetBSD systems.
* [tests]: Use printf(1) better.G. Branden Robinson2023-03-061-1/+1
| | | | | | Ensure we give printf a properly escaped backslash from the shell. Discovered on NetBSD 9.0; thanks to Bruno Haible for the report.
* [tests]: Have more tests report output.G. Branden Robinson2023-02-225-4/+8

* [tests]: Avoid failures when $GROFF_ENCODING set.G. Branden Robinson2023-02-225-0/+15

Thanks to Alexis for reporting this problem.
* tbl(1): Clarify behavior of `.T&`.G. Branden Robinson2023-02-221-1/+9
| | | | | Thanks to Brian Inglis for raising an ambiguity in the previous language.
* [grohtml]: Fix Savannah #63824 (1/2).G. Branden Robinson2023-02-223-4/+24
| | | | | | | | | | | | | | | | | [grohtml]: Revise tests to check for requisite programs at test time and skip if not found, rather than configuring them away at build time, which can cause a distribution archive to be incorrectly structured. * m4/groff.m4: Annotate requisite program list since we're violating the DRY principle. * src/roff/groff/groff.am (groff_TESTS): Populate unconditionally. * src/roff/groff/tests/html_works_with_grn_and_eqn.sh: * src/roff/groff/tests/smoke-test_html_device.sh: Check for requisite programs and skip test if any are not found. Fixes <https://savannah.gnu.org/bugs/?63824> (1/2).
* [man pages]: Define page-local `MR` fallback.G. Branden Robinson2023-02-2230-0/+450
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [man pages]: Provide page-local fallback definition of new `MR` macro. I didn't think I was going to have to do this, but the premier site on the web for viewing Linux man pages, Michael Kerrisk's man7.org, has been pulling snapshots of the pages themselves without upgrading the underlying macros, and so man page cross references set with `MR` are getting lost in its presentations. (I acknowledge: Ingo Schwarze warned me something like this could happen.) This definition is intended as a stopgap measure only. I want to revert this after groff 1.23 is released and has spread to some reasonable degree. * contrib/chem/chem.1.man: * contrib/eqn2graph/eqn2graph.1.man: * contrib/gdiffmk/gdiffmk.1.man: * contrib/glilypond/glilypond.1.man: * contrib/gperl/gperl.1.man: * contrib/gpinyin/gpinyin.1.man: * contrib/grap2graph/grap2graph.1.man: * contrib/hdtbl/groff_hdtbl.7.man: * contrib/mm/groff_mm.7.man: * contrib/mm/groff_mmse.7.man: * contrib/mm/mmroff.1.man: * contrib/mom/groff_mom.7.man: * contrib/pdfmark/pdfroff.1.man: * contrib/pic2graph/pic2graph.1.man: * contrib/rfc1345/groff_rfc1345.7.man: * man/groff.7.man: * man/groff_char.7.man: * man/groff_diff.7.man: * man/groff_font.5.man: * man/groff_out.5.man: * man/groff_tmac.5.man: * man/roff.7.man: * src/devices/grodvi/grodvi.1.man: * src/devices/grohtml/grohtml.1.man: * src/devices/grolbp/grolbp.1.man: * src/devices/grolj4/grolj4.1.man: * src/devices/gropdf/gropdf.1.man: * src/devices/gropdf/pdfmom.1.man: * src/devices/grops/grops.1.man: * src/devices/grotty/grotty.1.man: * src/devices/xditview/gxditview.1.man: * src/preproc/eqn/eqn.1.man: * src/preproc/eqn/neqn.1.man: * src/preproc/grn/grn.1.man: * src/preproc/pic/pic.1.man: * src/preproc/preconv/preconv.1.man: * src/preproc/refer/refer.1.man: * src/preproc/soelim/soelim.1.man: * src/preproc/tbl/tbl.1.man: * src/roff/groff/groff.1.man: * src/roff/nroff/nroff.1.man: * src/roff/troff/troff.1.man: * src/utils/addftinfo/addftinfo.1.man: * src/utils/afmtodit/afmtodit.1.man: * src/utils/grog/grog.1.man: * src/utils/hpftodit/hpftodit.1.man: * src/utils/indxbib/indxbib.1.man: * src/utils/lkbib/lkbib.1.man: * src/utils/lookbib/lookbib.1.man: * src/utils/pfbtops/pfbtops.1.man: * src/utils/tfmtodit/tfmtodit.1.man: * src/utils/xtotroff/xtotroff.1.man: * tmac/groff_man.7.man.in: * tmac/groff_me.7.man: * tmac/groff_ms.7.man: * tmac/groff_trace.7.man: * tmac/groff_www.7.man: Do it.

Thanks greatly to Alexis for identifying an issue with mandoc(1)'s handling of an earlier iteration of this fallback, and to John Gardner for identifying a method of detecting mandoc as the renderer at formatting time.

* neqn(1): Save and restore compatibility mode.G. Branden Robinson2023-02-211-0/+10
| | | | We don't actually need it at present, but we're about to.
* Revert "[man pages]: Define page-local `MR` fallback."G. Branden Robinson2023-02-2130-391/+0
| | | | | | | | | | | This reverts commit 18d708e489758636ff9e168eee2592591755eb61. Unfortunately my clever hack [sic] does not work with mandoc 1.14.5, causing that tool to truncate the entire text of the man page after the summary description. The good news is that there is a simpler replacement that works better, forthcoming.
* [groff]: Improve portability of a test.G. Branden Robinson2023-02-191-2/+3
| | | | | | | | | * src/roff/groff/tests/regression_savannah_58153.sh: Improve portability. Avoid the unpredictability of implementations when putting backslashes inside a groff-piped printf shell command inside a here document inside a command substitution by changing the groff escape character to something meaningless to the shell and to printf ('@'). Fixes a test failure on Solaris 11.
* [tests]: Don't test grohtml if unsupported.G. Branden Robinson2023-02-171-2/+4
| | | | | * src/roff/groff/groff.am (groff_TESTS) [!USE_GROHTML]: Don't test the 'grohtml' driver if we know it won't work.
* [tests]: Fix test failure on Solaris 11.G. Branden Robinson2023-02-171-3/+3
| | | | | | | | | | | | * src/roff/groff/tests/device_control_escapes_express_basic_latin.sh: Use printf(1), which is often a shell built-in command, more consistently. Double backslashes intended as literals in the format string, and single-quote format strings using them. Fixes test failure seen on Solaris 11 with GNU Bash 4.4 and ksh 93u+ (2012-08-01). Also spell failure message in full capitals, like all other tests producing this sort of output.
* [tests]: Send progress to standard error stream.G. Branden Robinson2023-02-161-3/+3
| | | | | * src/roff/groff/tests/device_control_escapes_express_basic_latin.sh: Send progress updates to standard error stream.
* tbl(1): Fix content and style nits.G. Branden Robinson2023-02-151-5/+12
| | | | | | * Consistently refer to "roff dummy character" instead of "non-printing input token". * Fix missing space in phrase.
* [groff]: Accommodate macOS od behavior in test.G. Branden Robinson2023-02-131-2/+2
| | | | | | | | | | | * src/roff/groff/tests/some_escapes_accept_newline_delimiters.sh: Weaken regexes in two test cases to accommodate excessive output from macOS's 'od' command. Resolves test failure seen on macOS. * HACKING: Add section "Writing Tests" and document the above since this is the second time I've cracked my shin on this. * ANNOUNCE: Drop notice of failing test case, now resolved.
* [docs]: Fix Savannah #68216.G. Branden Robinson2023-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | [docs]: Re-re-christen 'ESCAPE_AMPERSAND' ('\&'). Now call it a (non-transparent) "dummy character". Also rechristen 'ESCAPE_RIGHT_PARENTHESIS', ('\)') as the "transparent dummy character"; it has no impact on sentence-ending detection. * doc/groff.texi: * doc/meref.me.in: * man/groff.7.man: * man/groff_diff.7.man: * man/roff.7.man: * src/preproc/refer/refer.1.man: * tmac/groff_man.7.man.in: Do it. Fixes <https://savannah.gnu.org/bugs/?62816>. Thanks to Dave Kemper for the report and to the groff mailing list for the vigorous discussion. I don't expect my solution to please everyone. Also update references to the \& escape sequence in comments. ANNOUNCE: Update bug counts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch to using system's assert.h header file. It is futile to attempt to preserve compatibility with ISO C90 systems by providing a bespoke predicate-reporting assert() (a C99 feature) when gnulib, which we require, itself demands C99. This ensures that `static_assert` remains defined so that gnulib can use it.
