Hi,

I wonder about sbcl's sb-posix:chdir. I can call this function but directory, load etc. are not impressed. It does not change lisp current directory. Can anybody tell me how I can achieve this with sbcl?

(LispWorks knows cd, CMUCL has unix:unix-chdir)

Thanks

Andreas

I /think/ in SBCL you just change *default-pathname-defaults*.

Yep, does the job.

Thanks for the early help (watch the time) ;)

What is impressed, though, is the pwd of the process.

For example:


Linedit version 0.15.12 [smart mode]
(14:27:55) CL-USER> :sh pwd
/home/christian/lisp/image-maker

#<SB-IMPL::PROCESS :EXITED 0>
(14:28:00) CL-USER> (sb-posix:chdir "/home/christian")

0
(14:28:17) CL-USER> :sh pwd
/home/christian

#<SB-IMPL::PROCESS :EXITED 0>
(14:28:19) CL-USER> 



Where :sh simply calls a shell with the rest of the line.

It's not meant to be nitpicking, but might save you some 
misunderstandings in the future: the English term you want is "affected", 
not "impressed". "Impress" in English implies emotional impact and 
feeling of awe, which would be very confusing if applied to non-living 
things.

Cheers,

Yeah, well, I thought, that he used personification, and I just wanted
to play along :).

Thanks for the hint on linedit - that was that I was looking for :)
