* In groff commit 78e66624 on May 7 20:15:33 2021 +1000,Ingo Schwarze2022-06-261-1/+1
| | | | | | G. Branden Robinson changed the -T ascii rendering of \(sd, the "second" symbol, U+2033 DOUBLE PRIME, from '' to ". Follow suit in mandoc.
* With the improved escape sequence parser, it becomes easy to also improveIngo Schwarze2022-06-052-16/+16
| | | | | | | | | diagnostics. Distinguish "incomplete escape sequence", "invalid special character", and "unknown special character" from the generic "invalid escape sequence", also promoting them from WARNING to ERROR because incomplete escape sequences are severe syntax violations and because encountering an invalid or unknown special character makes it likely that part of the document content intended by the authors gets lost.
* following the fixed parsing direction of roff_expand() in roff.c rev. 1.388,Ingo Schwarze2022-05-191-5/+5
| | | | some diagnostics now appear in a more reasonable order, too
* delete the two pairs of extra blank lines from expected man(7) terminalIngo Schwarze2021-06-2815-60/+0
| | | | output that are no longer printed since man_term.c rev. 1.236
* test private use areas some more as they have proven fragileIngo Schwarze2021-06-028-38/+74

* Cleanup:Ingo Schwarze2021-06-024-53/+57
| | | | | | | | | | 1. Move invalid two-byte sequences after valid ones and make their descriptions easier to understand. 2. Replace the wrong and confusing expression "middle byte" with the correct term "start byte". 3. Add test lines for U+EFFFF and U+F0000. 4. Replace the unhelpful word "strange" with more descriptive terms. Arguably, nothing about this (or maybe everything?) is strange.
* The wcwidth(3) of Plane 15 and Plane 16 Private Use CharactersIngo Schwarze2021-06-022-4/+4
| | | | | was changed from 0 to 1. Adjust the test results accordingly. Issue reported by bluhm@
* Fix this test after the recent Unicode update in OpenBSD base.Ingo Schwarze2020-02-271-1/+1
| | | | | | | | | | The test uses U+07FF NKO TAMAN SIGN because it is the highest code point having a two-byte UTF-8 representation. This character is a new single-width punctuation character in Unicode 11, such that mandoc now does correct horizontal spacing. We already used the code point for the test before it was assigned, which resulted in weird spacing because wcwidth(3) returns -1 for unassigned code points.
* adapt to new <p> output logic (html.c rev. 1.260)Ingo Schwarze2019-09-037-14/+0

* Represent mdoc(7) .Pp (and .sp, and some SYNOPSIS and .Rs features)Ingo Schwarze2019-01-071-7/+7
| | | | | | | | | | | | | | | | | | | by the <p> HTML element and use the html_fillmode() mechanism for .Bd -unfilled, just like it was done for man(7) earlier, finally getting rid both of the horrible <div class="Pp"></div> hack and of the worst HTML syntax violations caused by nested displays. Care is needed because in some situations, paragraphs have to remain open across several subsequent macros, whereas in other situations, they must get closed together with a block containing them. Some implementation details include: * Always close paragraphs before emitting HTML flow content. * Let html_close_paragraph() also close <pre> for extra safety. * Drop the old, now unused function print_paragraph(). * Minor adjustments in the top-level man(7) node formatter for symmetry. * Bugfix: .Ss heads suspend no-fill mode, even though .Ss doesn't end it. * Bugfix: give up on .Op semantic markup for now, see the comment.
* Improve the ASCII rendering of \(Po (Pound Sterling)Ingo Schwarze2018-08-2116-90/+86
| | | | | and of the playing card suits to match groff, using feedback from Ralph Corderoy <ralph at inputplus dot co dot uk>.
* Fix some issues found looking at groff_char(7):Ingo Schwarze2018-08-218-12/+12
| | | | | | * Add two missing characters, \('Y and \('y. * The Weierstrass p is not capital, see http://unicode.org/notes/tn27/. * Add a groff-compatible ASCII transliteration for U+02DC: "~".
* Improve ASCII rendering of a few rare character escape sequencesIngo Schwarze2017-08-231-5/+5
| | | | | that can be changed unilaterally because groff fails to render them at all.
* catch up with ASCII renderings in chars.c rev. 1.72Ingo Schwarze2017-08-2316-99/+99

| | | | | | | | causes horrible churn anyway, profit of the opportunity to stop excessive testing, such that this is hopefully the last instance of such churn. Consistently use OpenBSD RCS tags, blank .Os, blank fourth .TH argument, and Mdocdate like everywhere else. Use -Ios=OpenBSD for platform-independent predictable output.

* Implement automatic line breakingIngo Schwarze2017-06-121-1/+1

* Style message about legacy man(7) date format in mdoc(7) documentsIngo Schwarze2017-06-111-0/+1
| | | | | and operating system dependent messages about missing or unexpected Mdocdate; inspired by mdoclint(1).
* add about 15 missing character escape sequences found in groff_char(7);Ingo Schwarze2017-06-0212-24/+64

* Disable three UTF-8 tests that expose bugs in wcwidth(3) in theIngo Schwarze2017-02-111-1/+1
| | | | | | | | | | | | native C libraries of illumos, Oracle Solaris 11, and SunOS 5.10. While it is useful to catch wcwidth(3) regressions on OpenBSD, the purpose of the *portable* mandoc regression suite is not to check the C library of the host system; that would just hide genuine mandoc portability issues in the noise. The remaining UTF-8 tests are still sufficient to establish that mandoc does the right thing. Issues reported by Sevan Janiyan <venture37 at geeklan dot co dot uk> after testing on OmniOS.

* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-0838-0/+1911
Both kristaps@ and wiz@ repeated asked for this, literally for years.
