Description Fredrik Lindberg 2005-08-18 20:20:15 UTC
The manual page for devd.conf(5) is very sparse.
This patch adds information on how you actually configure devd and explains
the syntax and meaning of the avaiable substatements.

Your other item descriptions begin with a capital letter.

My grep of 5.4 manpages found no "user land" and many "userland".

Some fonts don't show a single "`" well and .Dq seems to be more
popular (and I don't like either one).  That is, it's OK.

I would quote "0"; can't say why.

IIRC, two sentences should not share the same line.

I'm fairly sure it should "these directives", but "is" is correct.
(I see that it's problematic, though.)

Use .Li or .Dq Li or .Ql Li ?

I see nothing wrong with in-line quoting, but I wonder if other would.

Probably: .Va $device-name

It seems that "$" is not special char so doesn't need leading "\&".

.Va value
.Va variable

(I just checked; .Va underlines in my term.  .It does nothing noticable.)

.Va's

I'd use ".Ic ..." even if it's not interactive. Bold on my term.

IMO, "Subsystem" needs special treatment beyond ".Li", probably quotes.

I'll take the original manpage's word for it, but if it's really
a "shell construct" comment, then it can't appear at the beginning
of some whitespaces. For example try this with and without a
space before "#": sh -c 'aaa=bbb#ccc echo ddd$aaa'

Maybe "The installed" or "The distributed", because it might
not have the examples when the manpage is read.

"has many examples."

I wonder if that busy file doesn't belong in some "sample" directory.

This was unintentional, the "notify" statement were added to an
original part of the manual where non-capital letters were used.
In my opinion they should all begin with a captial letter.

I took a quick look at some other manuals, .Ql seems to be used
to quote single characters while .Dq is used to quote words.

You're probably right.

Maybe even "executed" ?

Inserting a hard break between those lines? even though they
are so closely related?

The original manual used "substatements", I were about to change
it to "sub-statements" but I never did it.

Well, a sub-statement is a statement and a statement can have 
sub-statements :)
But, you're right, it's probably better to use sub-statements for clarity.

I went over that sentence like a 100 times while writing, but since
english isn't my native language I really can't say which to use.

I confirmed this, devd(8) accepts " # foo" as a valid comment, so it's
not relly a "shell construct" comment, more of a "shell construct"-like 
comment.

"The installed" sounds fine.

Yes, moving the obvious examples to sample file would probably be a good
idea, keeping only the statements that is in use in /etc/devd.conf


I have addressed all of the above issues (proper quoting, choice
of words, .Va's and so on), but I'll wait until all issues are cleared
before posting a second patch.

Good idea.  The patch has some minor details that we may have to fix
before it's committed:

    * EOL spaces must be removed from the "new" lines
    * Some syntax and grammar mistakes have to be fixed (see below)

% +If two statements matches the same event, only the action of the statement with
% +highest priority will be carried out. In this way generic statements can be
% +overridden for devices/notifications that requires special attention. 

    "If two statements match the same event, only the action of the
    statement with the highest priority will be carried out.  This way
    generic statements can be overriden for events that require special
    attention."

% +.Pp
% +The general syntax to create a statement is as follows

Missing ':' at the end of the line.

% +.Ss Substatements
% +The following statements are supported within the 
% +.Ql options
% +statement.
% +.Bl -tag -width ".Ic directory"
% +.It Ic directory \*q/some/path\*q; 
% +Adds the given directory to the list of directories from which devd will read
% +configuration files. Any number of this directive is valid.

We should replace inline "devd" text with an .Xr reference to the
devd(8) manpage:

    from which
    .Xr devd 8
    will read

% +.It Ic pid-file \*q/var/run/devd.pid\*q;
% +Specifies pid file.

This is too terse.  What pid file?  Why pid file?  Whose pidfile?  It
may be obvious by looking at the filename of the sample pidfile, but
it's ok to expand this description a little, I think.

% +.It Ic set regexp-name \*q(some|regexp)\*q;
% +Creates a regular expression and assigns it to the variable
% +regexp-name, this variable is then avaiable through out the rest of 
% +the configuration file.
% +All regular expressions have an implicit ^$ around them.

The "regexp-name" string should be tagged with .Va (variable).  The two
sentences that are joined now by a comma are not really a single
sentence, but two complete, distinct sentences.  "Throughout" is only
one word.  The above should probably be rewritten as:

    .It Ic set regexp-name \*q(some|regexp)\*q;
    Creates a regular expression and assigns it to the variable
    .Va regexp-name .
    This variable is then available through out the rest of the
    .Pa devd.conf
    file.
    All regular expressions have an implicit
    .Dq Li ^$
    around them.

% +.El
% +.Pp
% +The following statements are supported within the

The final fullstop should really be a ':' character here.

% +.Bl -tag -width ".Ic directory"
% +.It Ic device-name \*qstring\*q;
% +Actually a shorthand to `match device-name'. Matches a device named string.

Literal quote characters shouldn't be present in mdoc manuals.  The word
'actually' sounds a bit superficial.

    .It Ic device-name \*qstring\*q;
    A shorthand for
    .Dq Li "match device-name" .
   This matches a device named
   .Dq Li string .

It may even be worth the effort to tag "string" with an .Ar macro.

    A shorthand for
    .Dq Li "match device-name" .
    This matches a device named
    .Ar string .

% +string is allowed to be a regular expression or a variable previously created
% +containing a regular expression.

    The
    .Ar string
    argument is allowed to be a regular expression...

% +The variable $device-name is avaiable for later use with the action-statement.

This has a typo (avaiable) and lacks some markup:

    The
    .Va "$device-name"
    variable can latter be used within the argument of the
    .Dq Li action
    statement and it will be replaced by the actual name of the device
    that matched the
    .Dq Li device-name
    argument.

% +.It Ic match \*qvariable\*q \*qvalue\*q;
% +Matches the content of value against variable. value can be a regular expression.
% +Not really needed during attach/detach events since the device-name statement

% +For a partial list of variables, see below.

Some formatting is missing here too.

    Matches the content of
    .Ar value
    against
    .Ar variable .
    The
    .Ar value
    argument may be a regular expression (see
    .Xr re_format 7 ).
    .Ic match
    statements are not very useful for setting up handlers for device
    attach or detach events, since this can be handled by
    .Ic device-name
    statements.
    See below for a partial list of available variable names.

We might also want to replace "below" with a section or subsection name.

% +.It Ic action \*qcommand\*q;
% +Command to execute upon a successful match. 
% +Example /etc/pccard_ether $device-name start

A lot of formatting is missing here too:

    Execute

    upon a successful match.

Same as what 'above'?  This is a duplicate of an existing description of
the "action" element, so it may be removed IMHO.

% +.Pp
% +The following statements are supported within the 
% +.Ql notify 
% +statement.

Colon instead of a fullstop before the beginning of a list, please.

It's also a good idea to use .Dq Li for multicharacter arguments,
instead of .Ql:

    The
    .Dq Li notify
    statement supports the following substatements:

% +The variable
% +.Ql $notify
% +is avaiable inside this statement and contains, possibly, a value depending
% +on which system and subsystem that delivered the event. 

This is misplaced, it has a typo, it uses .Ql with a multi-character
word (there's a tendency to use .Ql for single character arguments and
``.Dq Li foo'' for arguments that have more than 1 character), and does
not protect `$' (which may be a good idea)..  When the reader sees:

	The supported options of ``foo'' are:

then it's obvious that a list of the supported options follows.  Seeing
a second sentence is a bit unexpected and introduces an unwanted pause
between the announcement of a list and the list itself.  How about?

    Depending on the system and subsystem that delivers an event, the
    .Va notify

% +.Bl -tag -width ".Ic directory"
% +.It Ic match \*qsystem|subsystem|type\*q \*qvalue\*q;

Too long title.  How about?

    .Ss Predefined match-statement variable names

% +Partial list of variables and their possible values that can be used together
% +with the
% +.Ql match
% +statement.

"together with the match statement" seems a bit strange.  It's also
pretty useless to duplicate the title in slightly different words, just
to make sure that a short decription precedes the list.  If we add a
description at all, we might as well go all the way and write something
like this:

    The arguments of a
    .Dq Li match
    statement support expansion of variable names starting with a dollar
    sign
    .Pq Ql \$ .
    The predefined variable names are:
    .Bl -tag -width "manufacturer"
    ...
    .El

% +.Pp
% +.Bl -tag -width "manufacturer" -compact

There's no need for a .Pp before the .Bl request here.

% +.It Ic Variable
% +.Ic Possible value

.Ic is an "interactive command".  I'm sure this is not the right tag for
either the list item or the item description here.

% +.It bus
% +pccard[0-9]+, cardbus[0-9]+

It would be nice if regexps are tagged as "literal text" or quoted, or
both.

% +.Ss Notify matching 
% +Partial list of systems, subsystems and types used within the
% +.Ql notify
% +mechanism. 

As above, .Ql is not good for quoting multicharacter strings.  It's
better to use ``.Dq Li foo'' in this case.

% +.It ACAD
% +AC Line state ($notify=0 is offline, 1 is online)

Since ``$notify'' is a variable, it should be tagged as one.  The
capitalization of "Line" seems strange too.

    .It ACAD
    AC line state.  Offline when
    .Dq Li \$notify
    is 0, online when
    .Dq Li \$notify
    is 1.

% +.It Button
% +Button state ($notify=0 is power, 1 is sleep)
% +.It CMBAT
% +Battery events.
% +.It Lid

% +.El

See above for ``.Dq Li \$notify'' changes.

% +.El 
% +.El
% +.El

Triply nested lists are usually a sign that this may be split in at
least two sections.  This may not be the case here, but I didn't get a
chance to patch the manpage locally and see now the output looks like in
nroff with 80-column terminals.  I suspect the lines of the innermost
list are far too narrow to be readable.

% +.Sh EXAMPLES 
% +The file
% +.Pa /etc/devd.conf
% +contains numerous of different examples.

It's probably better to write:

	The "foo" file contains...

I'm not sure about this one, though.  It's just a vague feeling that
placing the "file" after the filename reads more natural.

You have made significant and very useful additions to the original
manpage, but there's still some mdoc work that needs to be done before
we can commit this.  Other, more experienced mdoc people from
freebsd-doc may have to look at the comments I made too, in case I
missed or misunderstood something.

``Any number of "foo" directives can be used.'' ?

>  > Use .Li or .Dq Li or .Ql Li ?

The ``.Ql'' request already makes its argument ``literal''.  The
canonical use of ``.Ql'' and ``.Dq Li'' is, AFAIK, one of the following:

	.Ql X
	.Dq Li XXX*

And a bit of shuffling around.  This sounds more natural in English:

	The
	.Va device-name
	variable

I would prefer making this a real "display" of literal text that can be
copy-pasted to the devd.conf file:

	.Bd -literal -offset indent
	notify "/etc/rc.d/power_profile $notify";
	.Ed

but this is just a personal preference, I guess.

A new patch is attached, that hopefully addresses all issues with
the first.
I also added a some real examples to the EXAMPLES section instead of
just a reference to /etc/devd.conf.

If this is good to commit, then would someone please commit it.  
usbd/usbd.conf are now gone in CURRENT and have good documentation 
for people making the switch to devd would be helpful.

I'll take this, I recently realized how crappy devd's docs are... 

Interested in updating the different busses man pages (pci(4), usb(4) 
along with others) w/ the keywords that you can match on?  (such as 
serial for usb)

Thanks for the patch, sorry it took so long to get committed...  If you 
would like to flesh out the variables that can be matched on, I'll commit 
the changes...
