[9fans] Trying to override 'cd' command

[9fans] Trying to override 'cd' command

[Ryan Gonzalez]

[-- Attachment #1: Type: text/plain, Size: 492 bytes --]

Coming from a bash world, I really like knowing what directory I'm in at
the prompt. I tried putting this at the end of 'lib/profile':



fn cd{
    builtin cd $1
    prompt=('{pwd}^'% ' '    ')
}

cd $HOME



However, it doesn't work! The 'cd' command seems to do what it normally
does. The prompt stays at 'term% '. Does nothing.

try it with 

fn cd{
	    builtin cd $1
	    prompt=(`{pwd}^'% ' '    ')
}

the difference is `{pwd} not '{pwd}.

Thanks for replying! Unfortunately, that doesn't change anything. Still
stuck at the 'term% ' prompt.

Invoke rc with -l flag (in acme middleclick on win rc -l).

Re: [9fans] Trying to override 'cd' command

[Anthony Sorace]

It works:

	: root; fn cd {builtin cd $* ; prompt=(': '`{pwd}^'; ' '	')}
	: root; cd
	: /usr/a; cd /tmp
	: /tmp; 

If you’re still having trouble, paste a transcript like that, so we can see what’s going on.

Note also that spaces in file names will screw up the easy version of this. If you’re on a filesystem that likes such things, you might instead want something like this:

	: /Library/Desktop; pwd            
	/Library/Desktop Pictures
	: /Library/Desktop; fn cd {builtin cd $* ; cwd=`{pwd} ; prompt=(': '$"cwd^'; ' '	')}
	: /Library/Desktop; cd .
	: /Library/Desktop Pictures;

I tried it in a fresh window, where it works for me.

I added it to the end of lib/profile.

Finally booted up Plan 9 again. Indeed, the function works when placed in
the shell, but *not in lib/profile*.

I'm putting in $HOME/lib/profile. That's the correct location, right?

Does this help you?

I think so...

So, in order to get my cd command, I enter '-' at the rc prompt? Is there some way for that to happen automatically?

Good evening,

no. You have to source the file $home/lib/profile by hand or invoke rc from a link called -rc, as rc -l or whatever.

Something is wrong. I don't wanna compile 20 KB of Go code to list files.
