this is now possible because -Tps now handles backspace overstriking.
|
|
the same way the mdoc(7) macros marked MDOC_JOIN do it.
In -Thtml, this removes bogus <br/> when the font macros are used
in no-fill mode; issue found by jsg@ in the Xcursor(3) SYNOPSIS.
As a bonus, this slightly reduces the size of the syntax tree.

and reduces the number of arguments of many functions.
While here, sprinkle some KNF.
No functional change.
|
|
Some functions need multiple parse points, some none at all,
and it varies whether any of them need to be passed around.
So better pass them as a separate argument, and only when needed.

1. Support specifying the .Bd and .Bl -offset as a macro default width;
while here, simplify the code handling the same for .Bl -width.
2. Correct handling of .Bl -offset arguments: unlike .Bd -offset, the
arguments "left", "indent", and "indent-two" have no special meaning.
3. Fix the scaling of string length -offset and -width arguments in -Thtml.
Triggered by an incomplete documentation patch from bentley@.

Correct ASCII rendering: \(lb \(<> \(sd
Make ASCII rendering agree with groff, using backspace overstrike:
\(da \(ua \(dA \(uA \(fa \(c* \(c+ \(ib \(ip \(/_ \(pp \(is \(dd \(dg

escape sequences just like it was earlier implemented for -Thtml.
Do not let control characters other than ASCII 9 (horizontal tab)
propagate to the output, even though groff allows them; but that
really doesn't look like a great idea.
Let mchars_num2char() return int such that we can distinguish invalid \N
syntax from \N'0'. This also reduces the danger of signed char issues
popping up.

representation, not for character escapes with unknown names.
According to groff, the latter produce no output, and we now warn
about them.
|
|
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.

Accept only 0xXXXX, 0xYXXXX, 0x10XXXX with Y != 0.
This simplifies mchars_num2uc().

In two cases, agreement is impossible because groff clobbers the

In a number of cases, groff rendering is so misleading that i chose

While here, also correct the \(la and \(ra Unicode code points.

Of course, this is only a minor improvement; it would be much better
to support non-ASCII characters in these output modes, but that
would require major changes that i'm not going to work on right now.
The main reason for doing this is that it allows to get ASCII output
closer to groff.

in one common, safe way instead of three different ways. In particular,
* skip NUL, it is used to mean "no output desired"
* deny 0x01-0x1F and 0x7F-0x9F, print REPLACEMENT CHARACTER instead
* print 0x20-0x7E literally or name-encoded, as required
* print characters above 0x9F numerically
|
|
In UTF-8 output, do not print anything if mchars_spec2cp() returns 0.
In particular, this repairs handling of zero-width spaces (\&).
While here, let mchars_spec2cp() return 0xFFFD instead of -1
if the character is not found, simplifying the using code.
In HTML output, do not print obfuscated ASCII characters and
do not test for one-char escapes, mchars_spec2cp() already does that.

|
sequences above codepoint 512 by doing a reverse lookup in the
existing mandoc_char(7) character table.
Again, groff isn't smart enough to do this and silently discards such
escape sequences without printing anything.
|
|
code points, provide ASCII approximations. This is already much better
than what groff does, which prints nothing for most code points.
A few minor fixes while here:
* Handle Unicode escape sequences in the ASCII range.
* In case of errors, use the REPLACEMENT CHARACTER U+FFFD for -Tutf8
and the string "<?>" for -Tascii output.
* Handle all one-character escape sequences in mchars_spec2{cp,str}()
and remove the workarounds on the higher level.

inside tables, sorry. So don't even try to parse tbl(7) blocks for
eqn(7) delimiters.

Put the steering into the roff parser rather than into the mdoc
parser such that it works for all macro languages and on both text
and macro lines.
Line breaks and blank characters generated before and after in-line
equations are not perfect yet, but let's do one thing at a time.

Does not yet take vertical rulers into account,
and does not do line breaks within table cells.

Require exactly 4, 5 or 6 hex digits and allow nothing else.
This avoids mishandling stuff like \[ua] and \C'uA' as Unicode
and also fixes underlining in eqn(7) -Thtml output which uses \[ul].

Get rid of the first fatal error, MANDOCERR_EQNSYNT.
In eqn(7), there is no need to be bug-compatible with groff, so there
is no need to abondon the whole equation in case of a syntax error.
In particular:
* Skip "back", "delim", "down", "fwd", "gfont", "gsize", "left",
"right", "size", and "up" without arguments.
* Skip "gsize" and "size" with a non-numeric argument.
* Skip closing delimiters that are not open.
* Skip "above" outside piles.
* For diacritic marks and binary operators without a left operand,
default to an empty box.
* Let piles and matrices take one argument rather than insisting
on a braced list. Let HTML output handle that, too.
* When rewinding, if the root box is guaranteed to match
the termination condition, no error handling is needed.
|

column vectors ("piles") and matrices are not yet pretty,
but everything else is now more or less readable
|

|

particularly useful when converting from other languages to mdoc(7);
