In particular, make it work in no-fill mode, too.

validity of character escape names and warn about unknown ones.
This requires mchars_spec2cp() to report unknown names again.
Fortunately, that doesn't require changing the calling code because
according to groff, invalid character escapes should not produce
output anyway, and now that we warn about them, that's fine.

Replace hard-coded widths and alignments with a minimal embedded stylesheet.
Do not use <p> because it cannot appear inside block macros.
Remove the "summary" attribute because it is not HTML5.

The .Bf block can contain subblocks, so it has to render as an
element that can contain flow content. But <em> cannot contain
flow content, only phrasing content. Rendering .Em and .Bf differently
would by unfortunate, and closing out .Bf before subblocks and
re-opening it afterwards would merely complicate both the C code
of the program and the generated HTML code. Besides, converting
.Em to semantic HTML markup would require some content to be put
into <em> and some into <i>, but we cannot automatically distinguish
which is which, so strictly speaking, we can't use semantic HTML
here but have to fall back to physical markup. Wonders of HTML...

The vast majority of .Em in real-world manuals is stress emphasis,
for which <em> is the correct markup. Admittedly, there are some
instances of .Em usage for alternate quality, for which <i> would
be a better match. Most of these are technical terms that neither
allow semantic markup nor are keywords - for the latter, .Sy would
be preferable. A typical example is that the shell breaks input into
.Em words .
Alternate voice or mood, which would also require <i>, is almost
absent from manuals.
We cannot satisfy both stress emphasis and alternate quality, so
pick the one that fits more often and looks less wrong when off.

remove trailing whitespace and blanks before tabs, improve some indenting;
no functional change
|
| |
|
|
|
| |
This improves the formatting of about 40 base manuals
and reduces groff-mandoc formatting differences in base by about 5%.

character without advancing the cursor position; implement it to
simply skip the next character, as it will usually be overwritten.
With this change, the pod2man(1) preamble user-defined string \*:,
intended to render as a diaeresis or umlaut diacritic above the
preceding character, is rendered in a slightly less ugly way,
though still not correctly. It was rendered as "z.." and is now
rendered as ".".
Given that the definition of \*: uses elaborate manual \h positioning,
there is little chance for mandoc(1) to ever render it correctly,
but at least we can refrain from printing out a spurious "z", and
we can make the \z do something semi-reasonable for easier cases.

Implement .Rv in -Tman.
Let -man -Tman work a bit like cat(1).
Add the -Ofragment option to -T[x]html.
Minor fixes in -T[x]html.
Lots of apropos(1) and -Tman code cleanup.

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.

* Unicode output support (no Unicode input yet, though).
* Refactoring: completely handle predefined strings in roff.c.
- New function mandoc_escape() replaces a2roffdeco() and mandoc_special().
- Start using mandoc_getarg() in mdoc_argv.c.
- Clean up parsing of delimiters in mdoc(7).
* And many minor fixes and lots of cleanup.

Change how -Thtml behaves with tables: use multiple rows, with widths
set by COL, until an external macro is encountered. At this point in
time, close out the table and process the macro. When the first table
row is again re-encountered, re-start the table. This requires a bit of
tracking added to "struct html", but the change is very small and
follows the logic of meta-fonts. This all follows a bug-report by
joerg@.

* .T} can be followed by a delimiter, then more data.
* Do not limit table column widths (improves terminfo(5)).
* Let numerical cells respect explicitly specified minimum cell widths.
* Let terminal output survive missing data cells.
* Parse and ignore arguments in parentheses on layout cell specifications.
* Move tbl_calc() into out.c such that it can be used by all frontends.
* Give tables an HTML class.
* Some cleanup in tbl -Thtml code.
All code by kristaps@.

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

In particular, use <SMALL> for .SM and <CODE> for .Dl.
Use <B> for bold and <I> for italic in general.
Also call this mandoc 1.10.8 now, as it is functionally equivalent,
even though one one set of refactoring patches has not been merged
yet because it conflicts with our tbl(1) handling.

in particular, use <B>, <I> and <U> where appropriate.
Provide relative widths for header and footer lines.
Manuals: More concise short descriptions of output modes.
Correct a few places still talking about CSS2 to say CSS1.
Code examples should use .Dl, not .D1.
|
| |
|
|
|
|
| |
Use less <DIV>, use more <H1>, <H2>, <P>, <BR>, <PRE>, <UL>, <OL>, <DL> etc.
Triggered by input from Will Backman.
Remove CSS2 note in mandoc.1, which is no longer true.

* support the .in macro in man(7)
* support minimal PDF output
* support .Sm in mdoc(7) HTML output
* support .Vb and .nf in man(7) HTML output
* complete the mdoc(7) manual
bug fixes:
* do not let mdoc(7) .Pp produce a newline before/after .Sh; reported by jmc@
* avoid double blank lines related to man(7) .sp and .br
* let man(7) .nf and .fi flush the line; reported by jsg@ and naddy@
* let "\ " produce a non-breaking space; reported by deraadt@
* discard \m colour escape sequences; reported by J.C. Roberts
* map undefined 1-character-escapes to the literal character itself
maintenance:
* express mdoc(7) arguments in terms of an enum for additional type-safety
* simplify mandoc_special() and a2roffdeco()
* use strcspn in term_word() in place of a manual loop
* minor optimisations in the -Tps and -Thtml formatting frontends

1) Proper .Bk support: allow output line breaks at input line breaks,
but keep input lines together in the output, finally fixing
synopses like aucat(1), mail(1) and tmux(1).
2) Mostly finished -Tps (PostScript) output.
3) Implement -Thtml output for .Nm blocks and .Bk -words.
4) Allow iterative interpolation of user-defined roff(7) strings.
Also contains some minor bugfixes and some performance improvements.

avoid the bad parts of 1.9.23, and keep local patches.
Input in general:
* Basic handling of roff-style font escapes \f, \F.
* Quoted punctuation does not count as punctuation.
mdoc(7) parser:
* Make .Pf callable; noted by Claus Assmann.
* Let .Bd and .Bl ignore unknown arguments; noted by deraadt@.
* Do not warn when .Er is used outside certain sections.
* Replace mdoc_node_free[list] by mdoc_node_delete.
* Replace #define by enum for rew*() return values.
man(7) parser:
* When .TH is missing, use default section and date.
Output in general:
* Curly braces do not count as punctuation.
* No space after .Fl w/o args when a macro follows on the same line.
HTML output:
* Unify PAIR_*_INIT macros, introduce new PAIR_ID_INIT().
* Print whitespace after, not before .Vt .Fn .Ft .Fo.
Checked that all manuals in base still build.

* corrected .Vt handling (spotted by Joerg Sonnenberger)
* corrected .Xr argument handling (based on my patch)
* removed \\ escape sequence (because it is for low-level roff only)
* warn about trailing whitespace (suggested by jmc@)
* -Txhtml support
* and some general cleanup and doc improvements

correctness/functionality:
- bugfix: do not die when overstep hits the right margin
- new option: -fign-escape
- and various HTML features
portability:
- replace bzero(3) by memset(3), which is ANSI C
- replace err(3)/warn(3) by perror(3)/exit(3), which is ANSI C
- iuse argv[0] instead of __progname
- add time.h to various files for FreeBSD compilation
simplicity:
- do not allocate header/footer data dynamically in *_term.c
- provide and use malloc frontends that error out on failure
