(mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified) |
|
|
|
- When there is free text in the SYNOPSIS and that free text contains |
|
the .Nm macro, groff somehow understands to treat the .Nm as an in-line |
|
macro, while mandoc treats it as a block macro and breaks the line. |
|
No idea how the logic for distinguishing in-line and block instances |
|
should be, needs investigation. |

--- missing misc features ---------------------------------------------- |
|
|
|
- clean up escape sequence handling, creating three classes: |
|
(1) fully implemented, or parsed and ignored without loss of content |
|
(2) unimplemented, potentially causing loss of content |
|
or serious mangling of formatting (e.g. \n) -> ERROR |
|
see textproc/mgdiff(1) for nice examples |
|
(3) undefined, just output the character -> perhaps WARNING |
|
|
|
- The \t escape sequence is the same as a literal tab, see for example |
|
the ASCII table in hexdump(1) where |
|
.Bl -column \&000_nu \&001_so \&002_st \&003_et \&004_eo |
|
.It \&000\ nul\t001\ soh\t002\ stx\t003\ etx\t004\ eot\t005\ enq |
|
produces |
|
000 nul 001 soh 002 stx 003 etx 004 eot 005 enq |
|
and the example in oldrdist(1) |
|

- .%T can have trailing punctuation. Currently, it puts the trailing |
* formatting issues: gratuitious differences |
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. |

Found in mount_nfs(8) and exports(5), search for "Appendix". |

then the number of balnks minus one |

- Trailing isolated dots lack EOS for some macros. |

This cannot use mandoc_eos() because groff only does EOS |

for isolated dots at least in some of these cases. |

Affected macros included those using in_line_eoln(). |

on the next line, it must be indented by -width, not width+1; |

see "rule block|pass" in OpenBSD ifconfig(8). |

- When the -width string contains macros, the macros must be rendered |
|
before measuring the width, for example |

.Bl -tag -width ".Dv message" |
