* Correctly calculate required column widths for tables containingIngo Schwarze2021-09-072-3/+20
| | | | | | | cells that horizontally span columns which contains "n" (number) formatted cells on other rows. This requires updating total column widths from "n" formatted cells before starting width distribution from the spanning cells to their constituent columns.
* Support two-character font names (BI, CW, CR, CB, CI)Ingo Schwarze2021-08-108-19/+50
| | | | | | | | | | | | | | | | | | | | | | | | in the tbl(7) layout font modifier. Get rid of the TBL_CELL_BOLD and TBL_CELL_ITALIC flags and use the usual ESCAPE_FONT* enum mandoc_esc members from mandoc.h instead, which simplifies and unifies some code. While here, also support CB and CI in roff(7) \f escape sequences and in roff(7) .ft requests for all output modes. Using those is certainly not recommended because portability is limited even with groff, but supporting them makes some existing third-party manual pages look better, in particular in HTML output mode. Bug-compatible with groff as far as i'm aware, except that i consider font names starting with the '\n' (ASCII 0x0a line feed) character so insane that i decided to not support them. Missing feature reported by nabijaczleweli dot xyz in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=992002. I used none of the code from the initial patch submitted by nabijaczleweli, but some of their ideas. Final patch tested by them, too.
* delete the two pairs of extra blank lines from expected man(7) terminalIngo Schwarze2021-06-2829-116/+0

* The GNU tbl(1) program contained in the groff package internallyIngo Schwarze2020-10-256-6/+6
| | | | | | | | | | | | | | | | | | uses roff(7) tabulator settings to implement tables, and it used to leak the changed tabulator settings from tables to the subsequent roff(7) code. In mandoc/tbl_term.c rev. 1.54 (June 17, 2017), code was added to be bug-compatible with groff. In commit d0e03cf6 (Oct 20, 2020), GNU tbl(1) changed behaviour to save the tabulator settings before starting a table and restore them afterwards. Adjust mandoc for compatibility. Since mandoc implements tables without using roff(7) tabulator settings, saving and restoring tabulator settings is not needed in mandoc. Simply deleting the code that changed tabulator settings by reverting tbl_term.c rev. 1.54 is sufficient in mandoc. Also adjust the desired output of the regression tests to match the new behaviour of both groff and mandoc.
* Ignore unreasonably large spacing modifiers in tbl layouts.Ingo Schwarze2020-09-016-4/+120
| | | | | | Jan Schreiber <jes at posteo dot de> ran afl on mandoc and it turned out mandoc tried to use spacing modifiers so large that they would trigger assertion failures in term_ascii.c, function locale_advance().
* test tbl_term.c rev. 1.73 and tbl_data.c rev. 1.53:Ingo Schwarze2020-01-116-11/+39
| | | | | incomplete short layout lines followed by longer lines, and spans at the beginning of layout lines
* Simplify maintainer targets in OpenBSD: EQN and TBL variablesIngo Schwarze2020-01-081-11/+2
| | | | | | no longer exist and NROFF/NOPTS were replaced with GROFF/GOPTS. This doesn't change how things work in the protable version of the test suite.
* When all cells in a tbl(1) column are empty, set the column widthIngo Schwarze2019-12-313-2/+97
| | | | | to 1n rather than to 0n, in the same way as groff does. This fixes misformatting reported by bentley@ in xkeyboard-config(7).

* Do not access a NULL pointer if a table contains a horizontal lineIngo Schwarze2019-06-113-2/+99
| | | | | | next to a table line having fewer columns than the table as a whole. Bug found by Stephen Gregoratto <dev at sgregoratto dot me> with aerc-config(5).
* Since resetting of offsets works quite differently in man(7) and mdoc(7),Ingo Schwarze2019-01-313-2/+29
| | | | | test table centering in an mdoc(7) document as well. Related to tbl_term.c rev. 1.67.
* It turns out association of tbl spans with layout rows is simpler thanIngo Schwarze2017-07-044-3/+48

| | | | | | | | 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.

* Multiple tbl(7) improvements:Ingo Schwarze2017-06-165-3/+12052
| | | | | | | | | | | | * Do not discard data that lacks a matching layout cell but remains within the number of columns of the table as a whole. * Do not insert dummy data rows for any layout row starting with a horizontal line, but only for layout rows that would discard all the data on a matching non-empty data row. * Print horizontal lines specified in the layout even if there is no matching data cell. * Improve the logic for extending vertical lines to adjacent rows, for choosing cross marks versus line segments, and some related details.

| | | | | | | widths of the remaining columns is already wider than the line length, underflowing size_t and dying from ENOMEM is the wrong plan. Instead, simply refrain from expanding anything in such a situation, avoiding a crash that tb@ found with afl.
* Really commit some files that failed to get committed in this commit:Ingo Schwarze2017-03-091-0/+1
| | | | | | | Now that markdown output is tested for almost everything, test all input files in -T markdown output mode by default and only mark those files with SKIP_MARKDOWN that are not to be tested. Much easier to read, and almost minus 40 lines of Makefile code.
* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-0854-0/+1329
Both kristaps@ and wiz@ repeated asked for this, literally for years.
