Many issues are annotated for difficulty as follows: |
| |
|
| |
- loc = locality of the issue |
| |
* single file issue, affects file only, or very few |
| |
** single module issue, affects several files of one module |
| |
*** cross-module issue, significantly impacts multiple modules |
| |
and may require substantial changes to internal interfaces |
| |
- exist = difficulty of the existing code in this area |
| |
* affected code is straightforward and easy to read and change |
| |
** affected code is somewhat complex, but once you understand |
| |
the design, not particularly difficult to understand |
| |
*** affected code uses a special, exceptionally tricky design |
| |
- algo = difficulty of the new algorithm to be written |
| |
* the required logic and code is straightforward |
| |
** the required logic is somewhat complex and needs a careful design |
| |
*** the required logic is exceptionally tricky, |
| |
maybe an approach to solve that is not even known yet |
| |
- size = the amount of code to be written or changed |
| |
* a small number of lines (at most 100, usually much less) |
| |
** a considerable amount of code (several dozen to a few hundred) |
| |
*** a large amount of code (many hundreds, maybe thousands) |
| |
- imp = importance of the issue |
| |
* mostly for completeness |
| |
** would be nice to have |
| |
*** issue causes considerable inconvenience |
| |
|
| |
Obviously, as the issues have not been solved yet, these annotations |
| |
are mere guesses, and some may be wrong. |

| - the roff parser doesn't tolerate additional characters between |
- The abort() in bufcat(), html.c, can be triggered via buffmt_includes() |
| a macro and the \} terminating a conditional block, e.g. |
by running -Thtml -Oincludes on a file containing a long .In argument. |
| .if n \{ |
Fixing this will probably require reworking the whole bufcat() concept. |

- \\ in high-level macro arguments |
| |
Currently, \\ is expanded in two situations: |
| |
1) macro and string definition (roff.c setstrn()) |
| |
2) macro argument parsing (mandoc.c mandoc_getarg()) |
| |
For user defined macros, the second happens in time because of ROFF_REPARSE. |
| |
But for standard high-level macros, it only happens after entering the |
| |
high level parsers, which is too late because the code doesn't get |
| |
back to roff.c roff_res() from that point. Because this requires |
| |
distinguishing requests, user-defined macros and standard macros |
| |
on the roff_res() level, it is hard to solve without the parser reorg. |

of .ad b, which we don't have either. Found in cksum(1). |

- .%T can have trailing punctuation. Currently, it puts the trailing |
| |
punctuation into a trailing MDOC_TEXT element inside its own scope. |
| |
That element should rather be outside its scope, such that the |
| |
punctuation does not get underlines. This is not trivial to |
| |
implement because .%T then needs some features of in_line_eoln() - |
| |
slurp all arguments into one single text element - and one feature |
| |
of in_line() - put trailing punctuation out of scope. |

- Trailing punctuation after .%T triggers EOS spacing, at least |
| |
outside .Rs (eek!). Simply setting ARGSFL_DELIM for .%T is not |
| |
the right solution, it sends mandoc into an endless loop. |

--- PDF issues --------------------------------------------------------- |

|
| |
- PDF output doesn't use a monospaced font for .Bd -literal |
| |
Example: "mandoc -Tpdf afterboot.8 > output.pdf && pdfviewer output.pdf". |
| |
Search the text "Routing tables". |
| |
Also check what PostScript mode does when fixing this. |
