There are two programs listed below, both of which accomplish similar goals.  The first is the simplest to install, while the second is more powerful.  Note that either may be altered to use your favourite editor, but that the second is much more closely tied to Vim.

Note - this currently doesn't work with a regular user account under 2.6-6.  I'm investigating why -gwb

Note - this currently doesn't work when OpenQM is executed by xinetd under 2.6-6.   
 +
If you execute OpenQM from the command line it works ok.  It appears that the I/O redirection
 +
is somehow broken when OpenQM is executed as a server (accessed via telnet <hostname> <port>)

==Larger Program==

[[Image:Qm-vim.png|thumb|right|Editing the VIM program in Vim]]
 +
Written by Tom Potts.
 +
 
 +
This is a more sophisticated program with the beginnings of some extra usefulness.  The syntax highlighting is naive, but useful; the dynamic-file editing is dangerous, but works okay, and it is robust enough to work with multifiles and Q-pointers.  If enough people think this is worthwhile, I'll clean it up a bit and put it in the main repository.  Oh, and there has to be a better way to do the 'itempath' stuff -- any ideas, anyone?
 +
 
 +
'''DISCLAIMER''':
 +
If you use this program to edit an item in a dynamic file, it '''will''' overwrite it when you have finished editing.  It is very unsafe, and I'm not happy about it, but if you use it carefully it should be okay.  If you think of a neat way of avoiding this problem, please let me know!

There are two programs listed below, both of which accomplish similar goals. The first is the simplest to install, while the second is more powerful. Note that either may be altered to use your favourite editor, but that the second is much more closely tied to Vim.

Small Script

This little script was given to me by Tom Hoogenboom:

To use your favorite editor, just change "leafpad" to "vi", "pico", etc.

Save the program below in your GPL.BP file and globally catalog it. 

* 'nano' caller for system editor
s = @sentence
s = trim(s)
convert ' ' to @am in s
filename = s<2>
itemname = s<3>
*
es = \sh nano \:@path:\/\:filename:\/\:itemname
crt es
execute es
*
end

Note - this currently doesn't work when OpenQM is executed by xinetd under 2.6-6. If you execute OpenQM from the command line it works ok. It appears that the I/O redirection is somehow broken when OpenQM is executed as a server (accessed via telnet <hostname> <port>)

Larger Program

Editing the VIM program in Vim

Written by Tom Potts.

This is a more sophisticated program with the beginnings of some extra usefulness. The syntax highlighting is naive, but useful; the dynamic-file editing is dangerous, but works okay, and it is robust enough to work with multifiles and Q-pointers. If enough people think this is worthwhile, I'll clean it up a bit and put it in the main repository. Oh, and there has to be a better way to do the 'itempath' stuff -- any ideas, anyone?

DISCLAIMER: If you use this program to edit an item in a dynamic file, it will overwrite it when you have finished editing. It is very unsafe, and I'm not happy about it, but if you use it carefully it should be okay. If you think of a neat way of avoiding this problem, please let me know!

Installation

Save this program in GPL.BP as 'ITEMPATH', and compile it. 

function itempath(item.id)

$catalogue global

path = ""

for i = 1 to len(item.id)
   char = item.id[i,1]
   begin case
      case char = '"'
         path := '%Q'
      case char = '%'
         path := '%P'
      case char = '*'
         path := '%A'
      case char = '+'
         path := '%V'
      case char = ','
         path := '%C'
      case char = '/'
         path := '%S'
      case char = ':'
         path := '%X'
      case char = ';'
         path := '%Y'
      case char = '<'
         path := '%L'
      case char = '='
         path := '%E'
      case char = '>'
         path := '%G'
      case char = '?'
         path := '%Z'
      case char = '\'
         path := '%B'
      case 1
         path := char
   end case
next i

return path

end

Save this program in GPL.BP as 'VIM' and compile it.
