They were a maintenance and auditing nightmare because if you changed
one bit in there, stuff tended to break at seemingly unrelated places.
No functional change except getting rid of one bogus error message,
but minus 80 lines of code.

as a bonus, get rid of another call to rew_sub().

except that some error messages become less confusing.
Now the function is almost readable (but still requires
nineteen lines of comments for fourteen lines of code).

* Replace calls to rew_sub() with rew_last() - two less out of 18.
* No need to keep track of the body, it's always opened right after
the head and never used for anything in this function.

and elements under any and all circumstances, even handling some
bad block nesting now and then. Little surprisingly, this ends up
in excessive complexity and has caused many bugs in the past.
Start to slowly disentangle this mess by replacing calls to rew_sub()
immediately following mdoc_head_alloc() by the much simpler rew_last().
Gets rid of the first two rew_sub() calls out of twenty.
No functional change.

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.

Remove lots of lies, dozens of irrelevant implementation details,
and all references to groff versions older than 1.17. Move relevant
information to the pages where it belongs, and out of mandoc(1) in
particular. Add some missing general remarks to roff(7), where it
fits the character and purpose of the page much better.
|
|
|
|
|
|
|
|
| |
* When "define" fails, do not drop the whole equation.
* Free memory after "undef".
* Use standard mandoc error types instead of rolling our own.
* Delete obfuscating EQN_MSG() macro.
* Add function prototypes while here.
|
|
|
|
|
|
| |
* 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.

* 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.

* Continue parsing even if part of the input is invalid.
* Do not require whitespace between cell specifications.
* Allow tabs as well as blanks between modifiers.
* Mark the 'm' modifier as unsupported.
* Parse and ignore the 'p' and 'v' modifiers.

scaling units, and some manuals (e.g. in devel/grcs) actually use that,

Count special characters with the same width as ASCII characters
and treat all other escape sequences as if they had a width of 0.
Certainly not perfect, but a bit better.
For example, GNU RCS ci(1) needs this; reported by naddy@.

in the input stream (SOH, STX, ETX, ENQ, ACK, BEL, BS) for specific
purposes (leaders, backspace, delimiters, .tr), but making sure
these don't leak through to the output is tricky, so mark them as
unsupported for now.

This is of some relevance because the pod2man(1) preamble abuses it
for the icelandic letter Thorn, instead of simply using \(TP and \(Tp.
Missing feature found by sthen@ in DateTime::Locale::is_IS(3p).
