<rlb>technomancy got fennel into debian in time for the trixie release

<identity>is there an equivalent of shell's redirecting output to a file (like "yes >/dev/null") in Guile? should i just do the usual read-u8 -> write-u8 thing?

<ekaitz>identity: what do you mean? call a shell command with redirection? or your make your guile program redirect everything to a file?

<identity>ekaitz: i mean i have a port i got with open-port and i want to write all of it to a file

<identity>all of the program's output, that is

<ekaitz>identity: you can set the current-output-port to something else with `set-current-output-port`

<ekaitz>and then just write, as your program was doing

<identity>ekaitz: i do not think i understand what you are suggesting, how would set-current-output-port help here?

<ekaitz>if you already had your program writing to the current-output-port, redirecting it is just setting that to something else

<ekaitz>but what you want here is copy from one port to another

<ekaitz>and i think that's read from one and write to another like you suggested

<identity>what i am trying to do is, i get a pipe with open-input-pipe, for, say, the /bin/yes program, like (open-input-pipe "yes"), and then i want to write the output to a file, say /dev/null, so something like (sendfile (open-input-pipe "yes") "/dev/null"), but which actually works

<ekaitz>I see

<ekaitz>identity: untested https://paste.debian.net/1375679/ but something like that maybe?

<ekaitz>I'm missing the command in the open-input-pipe but whatever

<ekaitz>this is loading everything in memory, though

<ekaitz>maybe you prefer to read char by char

<identity>ekaitz: does not load for me

<ekaitz>what? it should!

<ekaitz> https://paste.debian.net/plain/1375679

<identity>ekaitz: i guess i could do that too, the data itself is pretty small. thanks!

<ekaitz>no problem!

<optimal>identity: what about something like https://paste.debian.net/1375680/

<ekaitz>oh that's a good one too

<optimal>is there a way to specify which POSIX clock to use with `(current-time)'?

<optimal>i'm currently trying to implement SRFI-170 but there doesn't seem to be a way to do this in the Guile Manual

<optimal>at least not without using FFI

<identity>optimal: i do not think there is a way to get monotonic time in Guile (without FFI/libraries, at least), current-time provides UNIX epoch time

<sneek>wb tohoyn

<tohoyn>sneek: botsnack

<sneek>:)

<optimal>identity: there is an implementation of monotonic time in SRFI-19 but i don't know how spec-compliant it would be if i just reused it

<optimal>i'm not sure if it's... POSIX-y enough
