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 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.

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.

After decoding numeric (\N) and one-character (\<, \> etc.)
character escape sequences, do not forget to HTML-encode the
resulting ASCII character. Malicious manuals were able to smuggle
XSS content by roff-escaping the HTML-special characters they need.
That's a classic bug type in many web applications, actually... :-(
Found myself while auditing the HTML formatter for safe output handling.

* Parsing macro arguments has to be done in copy mode,
which implies replacing "\t" by a literal tab character.
* Otherwise, render "\t" as the empty string, not as a 't' character.
This fixes formatting of the distfile example in the oldrdist(1) manual.
This also shows up in the unzip(1) manual as one of several issues
preventing the removal of USE_GROFF from the archivers/unzip port.
Thanks to espie@ for attracting my attention to the unzip(1) manual.

change any code but for renaming functions and types to be consistent
with other mandoc.h stuff. The reason for moving into libmandoc is that
the rendering of special characters is part of mandoc itself---not an
external part. From mandoc(1)'s perspective, this changes nothing, but
for other utilities, it's important to have these part of libmandoc.
Note this isn't documented [yet] in mandoc.3 because there are some
parts I'd like to change around beforehand.

so that everybody can use them. This follows the convention of
libXXXX.h being internal to a library and XXXX.h being the external
interface. Not only does this allow the removal of lots of redundant
NULL-checking code, it also sets the tone for adding new mandoc-global
routines.

Don't use it in new manuals, it is inherently non-portable, but we
need it for backward-compatibility with existing manuals, for example
in Xenocara driver pages.

This conflicted with a structure in chars.c, which was renamed.

O- because the underlying macro depends on \(*W, which a prior pod2man
preamble `tr' macro rewrites as "-". This is an error in groff as this
tramples on the real \(*W, or Greek omega.

We now have sufficient practical experience to know what we want,
so this is intended to be final:
- provide -Wlevel (warning, error or fatal) to select what you care about
- provide -Wstop to stop after parsing a file with warnings you care about
- provide consistent exit status codes for those warnings you care about
- fully document what warnings, errors and fatal errors mean
- remove all other cruft from the user interface, less is more:
- remove all -f knobs along with the whole -f option
- remove the old -Werror because calling warnings "fatal" is silly
- always finish parsing each file, unless fatal errors prevent that
This commit also includes a couple of related simplifications behind
the scenes regarding error handling.
Feedback and OK kristaps@; Joerg Sonnenberger (NetBSD) and
Sascha Wildner (DragonFly BSD) agree with the general direction.

Fixed flushed-out condition of \} causing subsequent arguments to be
truncated, when in fact the whole line should be passed through (if the
conditional succeeds) to the front-end and the \} ignored there.
Added regression test of this behaviour.

Breakable hyphens are cued in the back-ends (with ASCII_HYPH) and acted

Also cleaned up XML decl printing (no need for extra vars).
