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.

struct tbl_cell. No functional change, minus 40 lines of code.

empty-handed; so this is just KNF and some code simplifications,
no functional change.
|
|
* 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.

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.
|
|
* 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.
|
|
* 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.

and reduces groff/mandoc differences in base by about 1%

and a few missing <sys/types.h> inclusions; no code change.

remove trailing whitespace and blanks before tabs, improve some indenting;
no functional change

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.

that is already used almost everywhere instead of gratuitiously
inventing different names at four places. No functional change.

adding an implementation of the eqn(7) language
by kristaps@
So far, only .EQ/.EN blocks are handled, in-line equations are not, and
rendering is not yet very pretty, but the parser is fairly complete.

Again lots of cleanup and maintenance work by kristaps@.
- simplify error reporting: less function pointers, more mandoc_[v]msg
- main: split document parsing out of main.c into read.c
- roff, mdoc, man: improved recognition of control characters
- roff: better handling of if/else stack overflows
- roff: add some predefined strings for backward compatibility
- mdoc, man: empty sections are not errors
- mdoc: move delimiter handling to libmdoc
- some header restructuring and some minor features and fixes
This merge causes two minor regressions
that i will fix in separate commits right afterwards.

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@

there are still a few bugs, but fixing these will be easier in tree.

calculation routines. This gives us mostly sane table column widths.

This fixes (1) all escape sequences and (2) some aspects of indentation.
Table column widths are still way off, though.

Unchanged code from bsd.lv release 0.1.5, but without the main program.
Not yet linked to the build; next commit will integrate it into mandoc.
