[TxMt] Feature request: "see" like SubEthaEdit

[Eric Hsu]

1. I have appended a shell script that launches TM and allows piped 
input. I did not write the script; in fact, I merely found it in my 
~/bin directory and thought that it came with the standard TM 
install. The -c option lets you create a new file.

It does lack the crucial 'don't quit until editing is done' feature. 
Here are three kludges I can think of to get that feature. Given a 
-wait flag:

a. add a block at the end of the script that creates a $TM_FILE.lock 
in the same directory and checks every N seconds for the .lock file. 
When it's gone, quit the script. Then create a command that saves 
current file and deletes the .lock file. Finally, write a little 
macro that saves, closes the window and runs the 'delete .lock' 
command.

In a future version of TM that triggers scripts/commands on events, 
one can avoid the command and macro, and have 'Close Window' trigger 
the deletion of the lock file.

b. have the shell script loop and check for changes to the 
modification date on the file. Unfortunately, that means it will quit 
on the first save. But you don't need any fiddling with macros and 
commands.

c. call the Textmate Service from a (different) shell script. The TM 
Service definitely blocks whatever app calls it. In other contexts 
this might be a bug, but here it's great. However, I don't know how 
to pipe text to a Cocoa Service from the command line. This may be 
rather hard. Any ideas?
