Re: Unsupported nroff macros on MacOS X
Apologies. enter (send) before typing. on FreeBSD 13.1 fc [delimchar [padchar]]Define a delimiting and a padding character for fields. Currently unsupported. Also, fc is not recognised in mdoc as far as I can tell. A different mechanism might be needed no matter what. in which case, dropping use of fc and retaining man might work, but that said, this comment from the man 7 man on OSX: DESCRIPTION The man language was the standard formatting language for AT UNIX manual pages from 1979 to 1989. Do not use it to write new manual pages: it is a purely presentational language and lacks support for semantic markup. Use the mdoc(7) language, instead. -G

In my opinion, this is the best option.

According to the mandoc manuals: HISTORY The tbl utility, a preprocessor for troff, was originally written by M. E. Lesk at Bell Labs in 1975.

Unsupported nroff macros on MacOS X
So I noticed that after an upgrade to MacOS X, I started getting this warning on certain nmh man pages: This manpage is not compatible with mandoc(1) and might display incorrectly. After some digging, it turns out man(1) is a shell script and to make a long story short is running this command: mandoc -Tlint -Wunsupp Which returns this: mandoc: whom.man:140:2: UNSUPP: unsupported roff request: fc And some quick googling suggests that in fact the mandoc macros only support a subset of roff requests, and .fc aint one of them. I will admit that my roff-fu is not very good, but I took a look at this. It seems this is a common idiom for nmh man pages. Specifically (this is from packf(1) but it's similar everywhere else): .SH "PROFILE COMPONENTS" .fc ^ ~ .nf .ta 2.4i .ta \w'ExtraBigProfileName 'u ^Path:~^To determine the user's nmh directory ^Current\-Folder:~^To find the default current folder ^Msg\-Protect:~^To set mode when creating a new `file' .fi So as I vaguely understand it, the .fc line sets '^ as a field delimeter and '~' as the character to pad a field. .nf sets the following lines to no-fill mode. ".ta 2.4i" sets the tab stop to 2.4 inches. The following line sets the tab stop to the width of "ExtraBigProfileName" and 'u is the default horizontal span for the terminal (now that I look at it, I'm not sure why there are two .ta lines right after another). The following lines use '^' to delimine each field and the "~" to pad out each field. So you get something that is supposed to look like: PROFILE COMPONENTS Path:To determine the user's nmh directory Current-Folder: To find the default current folder Msg-Protect: To set mode when creating a new `file' But on MacOS X you now get: PROFILE COMPONENTS ^Path:~^To determine the user's nmh directory ^Current-Folder:~^To find the default current folder ^Msg-Protect:~^To set mode when creating a new `file' This isn't wonderful and I'd like to fix it, but I'm not sure what to do. Ideas include: - Tell MacOS X users to install groff(1) (the man(1) script will try to call groff if it encounters a warning like this from mandoc) - Switch to some other roff construct; I was under the impression that actual tabs would work? I'm not sure why tabs aren't used here. - Switch to tbl(1) macros which as far as I can tell are supported by mandoc and seem to work everywhere. Given my druthers I think I'd rather do the last one, since this kind of seems like a table! But I'd like to hear what other people think since I know there are people here with much greater roff-fu than I (I do not know when tbl(1) was created, but it wouldn't surprise me if MH predated it). --Ken

Re: mhl nocomponent
I use MH-E, which does it's header display/hiding outside of MH. In general, I like to see extra headers, but they have gotten way out of hand from the MS/Outlook space. We probably need a better list of common "this is junk" header list that probably has to have wildcards in it. signature.asc Description: PGP signature
