* Simplify by creating struct roff_node syntax tree nodes for tbl(7)Ingo Schwarze2017-07-081-12/+7
| | | | | | | | | | | | right from roff_parseln() rather than delegating to read.c, similar to what i just did for eqn(7). The interface function roff_span() becomes obsolete and is deleted, the former interface function roff_addtbl() becomes static, the interface functions tbl_read() and tbl_cdata() become void, and minus twelve linus of code. No functional change.
* Implement w layout specifier (minimum column width).Ingo Schwarze2017-06-081-0/+1
| | | | | Improve width calculation of text blocks. Reduces the groff/mandoc diff in Base+Xenocara by about 800 lines.
* modernize style: "return" is not a functionIngo Schwarze2015-10-061-8/+8
|
* Delete the redundant tbl span flags, just inspect the actual dataIngo Schwarze2015-01-301-4/+0
| | | | | | | | where needed, which is less fragile. This fixes a subtle NULL pointer access to tp->tbl.cols: Due to a bug in the man(7) parser, the first span of a table can end up in a .TP head, in which case tblcalc() was never called. Found by jsg@ with afl.
* Abolish struct tbl_head and replace it by an "int col" member inIngo Schwarze2015-01-301-6/+0
| | | | struct tbl_cell. No functional change, minus 40 lines of code.
* Auditing the tbl(7) code for more NULL pointer accesses, i came outIngo Schwarze2015-01-301-8/+7
| | | | | empty-handed; so this is just KNF and some code simplifications, no functional change.
* * Polish tbl(7) error reporting.Ingo Schwarze2015-01-281-14/+14
| | | | | | * Do not print out macro names in tbl(7) data blocks. * Like with GNU tbl, let empty tables cause a blank line. * Avoid producing empty tables in -Tman.
* For now, it can't be helped that mandoc tbl(7) ignores high-level macros,Ingo Schwarze2015-01-281-7/+7
| | | | | | but stop throwing away their arguments. This fixes information loss in a handful of Xenocara manuals, at the price of a small amount of formatting noise creeping through.
* Multiple parser and formatter fixes for line drawing in tbl(7).Ingo Schwarze2015-01-271-1/+5
| | | | | | | | | | | | * Allow mixing vertical line bars with the layout options of the preceding layout cell. * Correctly combine box options with layout lines. * Correctly print vertical lines in data rows, with the right spacing. * Correctly print cross markers and left and right ends of horizontal lines even if vertical lines differ above and below. * Avoid the bogus error message "no table data cells" when a table data section starts with a horizontal line. No increase in code size.
* Improve (or rather, rewrite) tbl(7) option parsing.Ingo Schwarze2015-01-261-17/+32
| | | | | | | | | | | | * Allow the layout to start after the semicolon on the options line. * Ignore leading commas. * Option arguments cannot contain closing parentheses. * Avoid needless UNSUPP messages. * Better ERROR reporting. * Delete unused "linesize" field in struct tbl_opts. * No need for static buffers. * Garbage collect one almost empty wrapper function. Improved functionality, but minus 40 lines of code.
* blank lines in tables do not need special handling; simplifies codeIngo Schwarze2015-01-211-5/+2
| | | | and reduces groff/mandoc differences in OpenBSD base by about 1%
* simplify by getting rid of ROFF_ERR in tbl(7) parsing; no functional changeIngo Schwarze2015-01-141-2/+4
|
* Get rid of HAVE_CONFIG_H, it is always defined; idea from libnbcompat.Ingo Schwarze2014-08-101-2/+2
| | | | | | Include <sys/types.h> where needed, it does not belong in config.h. Remove <stdio.h> from config.h; if it is missing somewhere, it should be added, but i cannot find a *.c file where it is missing.
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-11/+11
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* The files mandoc.c and mandoc.h contained both specialised low-levelIngo Schwarze2014-03-231-0/+1
| | | | | | | functions used for multiple languages (mdoc, man, roff), for example mandoc_escape(), mandoc_getarg(), mandoc_eos(), and generic auxiliary functions. Split the auxiliaries out into their own file and header. While here, do some #include cleanup.
* More cleanup: Consistently use the name "struct tbl_node *tbl"Ingo Schwarze2013-05-311-19/+19
| | | | | that is already used almost everywhere instead of gratuitiously inventing different names at four places. No functional change.
* Implement the first steps of equation parsing from within libmdoc.Kristaps Dzonsons2011-07-251-1/+5
| | | | | | This consists of a shim around the text parser that calls out to libroff if equation components exist on the line. Right now this will do nothing, as the equation delimiter always returns nil.
* Add config.h Glue for OpenIndiana (and older OpenSolaris) to build.Kristaps Dzonsons2011-04-041-0/+4
| | | | From a patch by Yuri Pankov, thanks!
* Step 1 of restructuring: libmandoc.h. Move all compiler-set-specificKristaps Dzonsons2011-03-221-1/+0
| | | | | | | | | | stuff into libmandoc.h, including old mdoc.h/man.h/roff.h functions now used by read.c. The motivation behind this is to tighten the relationship between the underlying compilers while keeping parse data hidden from general callers (e.g., main.c). While here, also move register values from mandoc.h into libmandoc.h as noted by schwarze@. See above for explanation.
* Consolidate messages. Have all parse-time messages (in libmdoc,Kristaps Dzonsons2011-03-201-7/+10
| | | | | | | | | libroff, etc., etc.) route into mandoc_msg() and mandoc_vmsg(), for the time being in libmandoc.h. This requires struct mparse to be passed into the allocation routines instead of mandocmsg and a void pointer. Then, move some of the functionality of the old mmsg() into read.c's mparse_mmsg() (check against wlevel and setting of file_status) and use main.c's mmsg() as simply a printing tool.
* Since tbl_data() can now produce multiple spans, let parsebuf()Ingo Schwarze2011-01-251-3/+9
| | | | | | | generate man(7) or mdoc(7) nodes for all these spans, not only for the last one. Restores the horizontal lines in the cpu(4/hppa) tables. ok kristaps@
* Support `T{' and `T}' data blocks. When a standalone `T{' isKristaps Dzonsons2011-01-041-1/+8
| | | | | | | 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.
* Make width calculations occur within tbl_term.c, not tbl.c. This allowsKristaps Dzonsons2011-01-031-160/+0
| | | | | | | | | | | | | | | | 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.

* Churn to get parts of 'struct tbl' visible from mandoc.h: rename theKristaps Dzonsons2011-01-021-18/+18
| | | | | | | 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 Dzonsons2011-01-011-0/+165
| | | | | | | | 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.
* Plug in the "head" concept for tables. A tbl_head specifies the fullKristaps Dzonsons2011-01-011-4/+8
| | | | | | | | | | 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@).

reference to a current tbl parse and routes ALL text into the tbl parse after stripping reserved words and making block-level pre-processing (e.g., `ig'). This is consistent with an analysis of embedded `TS/TE' in manuals with sprinkled -mdoc, roff, and -man macros. Fact of a parse is exposed to main.c by a return value (ROFF_TBL), which will trigger main.c to add a foreign parsed body to the -mdoc or -man parse stream. This interface isn't in yet, but will follow the parse-text functions in both libraries. I put this login in main.c because I don't want libroff calling directly into libmdoc or libman. As a consequence, a parsed row can be pushed directly into any -mdoc or -man context (put a `Bd -literal -offset indent' into a `TE/TS' block to see why this is necessary). It will then absorb formatting cues in the front-ends. A note on naming. I decided on libroff.h instead of tbl.h because this is purely within the roff layer. Separate tbl implementations will need, then, to interface with libroff. This is "how it should be" because tbl is tightly linked with roff in terms of `ds' and other formatting macros, as well as, of course, special characters and other roffisms.
