Hi Pan,
On a foreign distro I install the guix package 'man-db', add the
following to my .bashrc, and am able to access both system and guix
man pages.
export MANPATH=$MANPATH${MANPATH:+:}/usr/share/man

FTR, it's READ-CHANNEL-METADATA and friends in guix/channels.scm note that it's not the same thing as /etc/guix/channels.scm, even though they appear similar (https://issues.guix.gnu.org/53657). -- • attila lendvai • PGP: 963F 5D5F 45C7 DFCD 0A39 -- “People who have never gone to school have never developed negative attitudes toward exploring their world.” — Grace Llewellyn
Processing large amounts of files
Hi Guix,
I have a somewhat unusual workflow that requires me to do a number of
processes on numerous, but small input files. The original is a bit
unwieldy and takes several minutes to compile, but I've managed to
produce a more understandable and better performing example. Note,
that after a certain number of inputs, I get the following error:
info: .16 Loading workflow file `meow.gwl'...
info: 2.80 Computing workflow `cat'...
run: 12.96 Executing: /bin/sh -c
/gnu/store/kmssbjcdcabg9fh4nxscwwpnlb4px30h-gwl-meow.scm …
error: 13.01 Wrong type argument in position 1: #f
For comparison:
time cat /tmp/meow/{0..7769}
[…]
real 0m0,144s
user 0m0,049s
sys 0m0,094s
It takes GWL 6 times longer to compute the workflow than to create the
inputs in Guile, and 600 times longer than to actually execute the
shell command. I think there is room for improvement :)
Cheers
