Date: 9 Jan 92 20:47:44 GMT

I'm working on a macro (in vi) that would allow me
to automatically write the name of the file into
the current cursor location in the file.

I know that "%" seems to be the name of the file,
it seems that you can rename a file with

        :w %.new

I think I could usually simulate what I want with a
        :r !ls %

but there has to be a better way.

Yes!  I'd like that also.  Right now all I can do is ^G to display the
name, then cut it with the mouse (under X11) and paste it where I need
it.  But a macro would be so much nicer.

Usually, but not before the file has been written, else instead of
"filename" you'll get "filename not found".

would

Subject: VI: Changing case for an entire word...how did I do it?

Somehow, I managed to do this by accident. Just now, I did it again.
And the damned thing is that I don't know how!

Now, '~' will toggle the case of a character, but it seems to be immune to the
standard VI  [count] command [address modifier] syntax (i.e. '~w' will toggle
the case of the current character, and then move on to the next word).


		How did I do this?

If possible, please respond via mail...

Two people have suggested using awk, and their solutions involve doing
something with an intermediate file.  From within vi, you can filter
your file by doing the following.  On the top line of your
file, add the following line.

!Gawk '{printf "\%s\%8d\n", $0, NR}'

Next type

	1G"ayy

to put the top line (the one with awk on it) into the buffer a.
Next, put the cursor at the beginning of the first line of data
that you want to change.  Then, type

	@a

to tell vi to eat the contents of buffer a as keystrokes you have typed.
If you don't like the spacing, type a 'u' to undo the changes, and change
the '%8' to be '%5', or something.  Then start over at "Next type"
above.

Filtering and using the named buffers as macros are very useful parts
of vi.  Knowing how to use them can save you many hours of work...

local perhaps?).  Well, so what?  If you have a lot of macros defined in
your HOME/.exrc, you will find you start getting error msgs when you edit
in your HOME directory - you run the macro code out of buffer space.  The
thing is, if you have the same macro defined IDENTICALLY (or any other way)
both definitions appear in vi's macro buffer - I believe he only executes
the last one - but the others are still there.

Sigh.

One little colon!

If you're already inside 'vi', then typing
	:map t dd
would map 't' to 'dd'.

But that ':' doesn't belong in your .exrc file.

I am doing this in my .exrc file as:

map P :t dd

where P is the macro identifier to use when you want to execute the macro
and it works pretty well.

What version of vi are you using?

All versions I've ever seen allow you to type 1 (one) superfluous colon
at the start of an ex command.

And, frankly, I find myself doing that a lot when in ex mode.

When I try that, vi says "t requires a trailing address".

Wouldn't it be better to write:

map P :t 'd ^M

[As always, getting a ^M requires typing control-V control-M.]

[ Jos quotes from the Sun vi man page ... ]

On my system (SparcStation 1+, SunOS 4.1.1), vi reads .exrc in the
present directory, AND .exrc in my home directory.

If the EXINIT environment variable is defined, vi will use that
variable and only .exrc in the present directory, ignoring .exrc in my
home directory.

It also works in the ~/.exrc file ! This macro (and any macro) syntax is 
the same if you are either inside vi or if it's a line of your .exrc. 
The only difference is that in the first case, the macro is no longer 
valid after your current vi session.

i recently was dorking around with this stuff and realized that i
wanted to change my mappings based on the type of file i was editing.
i wrote the following csh file to do this:
----------------------------------------------------------------------
#! /bin/csh -f
set suffix = $argv[1]:e
if (-e ~/.exrc.$suffix) then
	/usr/ucb/vi +":so ~/.exrc.$suffix" $argv
else
	/usr/ucb/vi $argv
endif
----------------------------------------------------------------------
what this does is search in my home directory for files like ".exrc.c"
and ".exec.tex" for mappings for C and TeX source file mappings.  i
then just place my generic stuff in .exrc and the source-specific
stuff in the additional .exec.*.  if there isn't an associated file,
it just runs with the generic arguments.  pretty handy.  one problem i've
found is that vi doesn't seem to source the extra .exrc's when editing
an empty file.  oh well.
