Dust command oddities in OSX 10.10.1

[kidpollo]

Out of the box the command seems to depend on rlwrap which does not seem to be part of osx. Also readlink shows an illegal option --f

$ dust
readlink: illegal option -- f
usage: readlink [-n] [file ...]
usage: dirname path
/usr/local/bin/dust: line 20: rlwrap: command not found

After installing rlwrap I see other weird warnings:

$ dust repl
readlink: illegal option -- f
usage: readlink [-n] [file ...]
usage: dirname path
rlwrap: warning: on this system, the getopt() library function doesn't
grok optional arguments, so '-n' is taken as an argument to the -a option
Is this what you meant? If not, please provide an argument

warnings can be silenced by the --no-warnings (-n) option

dust help does not even work:

$ dust help
readlink: illegal option -- f
usage: readlink [-n] [file ...]
usage: dirname path
Error: Cannot open '/run.pxi'

I seem to have dust in the path:

$ which dust
/usr/local/bin/dust

I built and installed the non jut pixie-vm versions so I did not get the segfaults.

$ which pixie-vm
/usr/local/bin/pixie-vm

$ pixie-vm

Ughh seems you would need to install brew install coreutils and detect the OS so it can use greadlink ¬¬

[heyLu]

that's one way, but i'm fixing it for (hopefully) everyone else. wait a minute or two. :)

edit: done, could you try again?

[kidpollo]

ohh wait If you remove the -f seems to work :p

[kidpollo]

Cool! Is there an alternative to using rlwrap?

[heyLu]

The readline library (which we already use a bit) could handle the history and line editing functionality, but I don't know if it can do the bracket matching as well.

Closing this for now, rlwrap is mentioned in the README and maybe at some point pixie will take advantage of readlines capabilities by itself.
