Shell Programming and Scripting

Hi,

I'm using a complete command in tcsh this way, the echo cmd is just for the example :

Code:

complete echo 'p/1/`mypythonalias`/'

And that works just great returning what the python script is printing out.

However I want to give an argument to the python script to narrow down its results and here comes the problem. I tried many things I found on Internet :

Code:

complete echo 'p/1/`mypythonalias $1`/'
complete echo 'p/1/`mypythonalias \{print\ \$1\}`/'
complete echo 'p/1/`mypythonalias '"'"'{print\ \$1\}'"'"'`/'

And other examples using more backslashes but returning errors.

In any case, print $1 was never evaluated, this page on tcsh.org seems to say that it should be possible though :
tcsh.html/Builtin_commands.html#complete

But I couldn't get the example to work properly somehow.

Any help would be really appreciated

Thanks !
Chris

Little bump on that one, it would be really nice to get some help :-/

Thanks
Chris

You'll get a lot more help in this forum when dealing with shells that follow Bourne shell syntax than with shells that use csh style shell syntax. In Bourne shell syntax, command substitutions and positional variables are processed when they appear in a double-quoted string, but are not expanded when they appear inside a single-quoted string. I do not use csh or tcsh, but you might try:

Code:

complete echo "p/1/`mypythonalias $1`/"

instead of:

Code:

complete echo 'p/1/`mypythonalias $1`/'

Hi Don,

sorry for the bump, it's the first time I see it being a bother on a forum

Thanks for your help, sadly the double quote didn't fix my issue. I'll try other ideas

Thanks again !

I don't think you can pass arguments to your perl script like that.

From what I can see the environment variable $COMMAND_LINE should contain the fully typed command line which should be exported to your script.

So if you typed echo one two[^D] at the tcsh prompt, you would get "echo one two" in the COMMAND_LINE env variable available to your script.

Thx Chubler !

I couldn't exactly make it work with what you wrote but the $COMMAND_LINE put me on the right track and helped my research a lot and I found something which worked great !

Code:

complete echo 'p/1/`set cmd = ( $COMMAND_LINE ); mypythonalias $cmd[$#cmd]`/'

Thanks again for your help guys !
