* Support `T{' and `T}' data blocks. When a standalone `T{' isKristaps Dzonsons2011-01-048-23/+86
| | | | | | | encountered as a line's last data cell, move into TBL_PART_CDATA mode whilst leaving the cell's designation as TBL_DATA_NONE. When new data arrives that's not a standalone `T}', append it to the cell contends. Close out and warn appropriately.

* Fix spacing for tables to use term_len(). Also make term.c properlyKristaps Dzonsons2011-01-043-16/+23
| | | | recode ASCII_HYPHEN and ASCII_NBRSP before passing back for widths.
* Fix to make horizontal spanners in the layout be properly printed.Kristaps Dzonsons2011-01-045-55/+71
| | | | | | | mandoc also now warns (so does tbl(1)) if a horizontal spanner is specified along with data. While here, fix up some documentation and uncomment the tbl reference.

* Multiple man(7) .IP and .TP fixes started during p2k10:Ingo Schwarze2011-01-042-38/+35
| | | | | | | | | | | | | | | | | | | | | Affecting both -Tascii and -Thtml: * The .IP HEAD uses the second argument as the width, not the last one. * Only print the first .IP HEAD argument, not all but the last. Affecting only -Tascii: * The .IP and .TP HEADs must be printed without literal mode, but literal mode must be restored afterwards. * After the .IP and .TP bodies, we only want term_newln(), not term_flushln(), or we would get two blank lines in literal mode. * The .TP HEAD does not use TWOSPACE, just like .IP doesn't either. * In literal mode, clear NOLPAD after each line, or subsequent lines would get no indentation whatsoever. Affecting only -Thtml: * Only print next-line .TP children, instead of all but the first. OK kristaps@ on the -Tascii part; and: "Can you work this into man_html.c, too?"
* Partial cleanup of argument count validation in mdoc(7):Ingo Schwarze2011-01-033-70/+74
| | | | | | | | | | | | * Do not segfault on empty .Db, .Rs, .Sm, and .St. * Let check_count() really throw the requested level, not always ERROR. * Downgrade most bad argument counts from ERROR to WARNING. * And some related internal cleanup. Looks fine to kristaps@. Note that the macros using eerr_ge1() still need to be checked at a later time; but as all the others are done, let's use what we already have.
* Calling a macro with fewer arguments than it is defined with is OK;Ingo Schwarze2011-01-031-2/+2
| | | | | the remaining ones default to the empty string, not to NULL. Regression reported and fix tested by kristaps@.
* Unify roff macro argument parsing (in roff.c, roff_userdef()) and man macroIngo Schwarze2011-01-034-117/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | argument parsing (in man_argv.c, man_args()), both having different bugs, to use one common macro argument parser (in mandoc.c, mandoc_getarg()), because from the point of view of roff, man macros are just roff macros, hence their arguments are parsed in exactly the same way. While doing so, fix these bugs: * Escaped blanks (i.e. those preceded by an odd number of backslashes) were mishandled as argument separators in unquoted arguments to user-defined roff macros. * Unescaped blanks preceded by an even number of backslashes were not recognized as argument separators in unquoted arguments to man macros. * Escaped backslashes (i.e. pairs of backslashes) were not reduced to single backslashes both in unquoted and quoted arguments both to user-defined roff macros and to man macros. * Escaped quotes (i.e. pairs of quotes inside quoted arguments) were not reduced to single quotes in man macros. OK kristaps@ Note that mdoc macro argument parsing is yet another beast for no good reason and is probably afflicted by similar bugs. But i don't attempt to fix that right now because it is intricately entangled with lots of unrelated high-level mdoc(7) functionality, like delimiter handling and column list phrase handling. Disentagling that would waste too much time now.

| | | | | | | | this may be moved to tbl.7, but for the time being, keep it in the document as it's developed. Also note that my handling of horizontal rules in layouts needs some work.

* Start using term_strlen() instead of strlen(). tbl_term.c can nowKristaps Dzonsons2011-01-031-34/+39
| | | | | properly handle embedded escapes when calculating its widths. NOTE: this doesn't yet apply to the decimal-point calculation.
* Make width calculations occur within tbl_term.c, not tbl.c. This allowsKristaps Dzonsons2011-01-036-221/+245
| | | | | | | | | | | | | | | | for front-ends to make decisions about widths, not the back-end. To pull this off, first make each tbl_head contain a unique index value (0 <= index < total tbl_head elements) and remove the tbl_calc() routine from the back-end. Then, when encountering the first tbl_span in the front-end, dynamically create an array of configurations (termp_tbl) keyed on each tbl_head's unique index value. Construct the decimals and widths at this time, then continue parsing as before. The termp_tbl and indexes are required because we pass a const tbl AST into the front-end.
* Tiny edit required after MDOC_HALT change.Kristaps Dzonsons2011-01-031-6/+1

* Make sure we don't continue recursively parsing once we've exited withKristaps Dzonsons2011-01-031-1/+9
| | | | | failure (this had caused some segfaults with the new assert() call in MAN_HALT and MDOC_HALT).
* Same treatment for MAN_HALT as for MDOC_HALT.Kristaps Dzonsons2011-01-032-29/+24

* Clarified the role of MDOC_HALT in libmdoc functions by having accessorKristaps Dzonsons2011-01-032-24/+23
| | | | | | | | | | functions assert() if they're called after MDOC_HALT is set. This makes more sense than returning 0 because this return value is used for parse errors, not programme-flow errors, and it's inconsistent to use the same value for both. Plus, prior to this, I'd return 0 without printing an error message, which would cause failure to go unreported to the operator.
* Fix table to print nicely (merging error). Also have -Ttree push out someKristaps Dzonsons2011-01-023-20/+32

* Turn on -Tascii tbl printing. The output still has some issues---I'mKristaps Dzonsons2011-01-026-7/+370
| | | | | | not sure whether it's in the header calculation or term.c squashing spaces or whatever, but let's get this in for general testing as soon as possible.
* Add some final bits necessary in the upcoming -Tascii tbl stuff.Kristaps Dzonsons2011-01-024-5/+19

* Churn to get parts of 'struct tbl' visible from mandoc.h: rename theKristaps Dzonsons2011-01-028-91/+97
| | | | | | | existing 'struct tbl' as 'struct tbl_node', then move all option stuff into a 'struct tbl' in mandoc.h. This conflicted with a structure in chars.c, which was renamed.
* Merge in the width, decimal, and positioning code for individual data rowsKristaps Dzonsons2011-01-011-1/+166
| | | | | | | | from tbl.bsd.lv. This is more or less verbatim, less queue macros and also a check for NULL layout. This concludes the back-end parsing for a little while, as the front-end display may now be configured.
* Add a warning if a data cell has no layout. Also make -Ttree show thisKristaps Dzonsons2011-01-014-5/+17
| | | | with a little star next to the entry (yeah, this is mostly for testing).
* Plug in the "head" concept for tables. A tbl_head specifies the fullKristaps Dzonsons2011-01-014-25/+155
| | | | | | | | | | layout for each row, including vertical spacers. One grabs the tbl_head for a row and iterates through each entry, plugging data from the tbl_span into the header as appropriate. This is pulled in more or less verbatim from tbl.bsd.lv. In fact, this is verbatim except that lists macros are made into hard-coded lists (for compatibility, as long-ago noted by joerg@).

* Put parsed tables into a queue that's cleared at the end of parsing.Kristaps Dzonsons2010-12-313-72/+55

* Plan9 has a man(7) implementation that looks extremely archaic,Ingo Schwarze2010-12-301-1/+6
