Hi,

(I hope this is the right place for this question)

I'm on a newly installed Guix machine, and have done the following:

   guix pull
   guix install gwl
   guix workflow

The output of the last is:

   guix: workflow: command not found
   Try `guix --help' for more information

As far as I can see from the gwl installation instructions [1], this 
should work out of the box. However, from inside guix repl I also cannot 
load the (guix scripts workflow) module, so I assume that perhaps the 
GUIX_EXTENSIONS_PATH variable is set incorrectly, even if it says it 
shouldn't be necessary to set it manually when on a guix system (I don't 
really know what to set it to, however ...).

But I'm relatively new to both guix and guile, so I may have also just 
missed something obvious. Can anyone help me out?

Thanks!

Hi stuebinm,

I’m not sure! :)

This list is fine, but we also have a dedicated GWL list: 
https://lists.gnu.org/archive/html/gwl-devel/

I’m sorry about this!  The documentation really is not clear 
enough here.  Annoyingly, you currently do need to set 
GUIX_EXTENSIONS_PATH manually.  The reason for that is that Guix 
doesn’t yet do this automatically when using “guix pull”.

There is also a reason why the documentation is so vague: we 
hadn’t really come to consensus about the exact behavior of 
GUIX_EXTENSIONS_PATH.  I intended to update the documentation once 
we had this figured out.

For now, I suggest you set it like this:

    export 
    GUIX_EXTENSIONS_PATH=$GUIX_PROFILE/share/guix/extensions/

where GUIX_PROFILE is the name of the profile directory where you 
installed the “gwl” package (in your case that’s likely just 
“$HOME/.guix-profile”).

~~~

I should also note that there are a couple of known bugs in the 
GWL at this point, and I’m working on adding a DRMAA backend to 
submit workflow jobs to an HPC cluster.  There is no date for a 
new release yet, but I guess that in a few more weeks we will have 
accumulated enough fixes and features to announce a new release.

If you have a particular use-case in mind, I’d be very happy if 
you could tell us about it on gwl-devel, so that we can make sure 
the GWL grows in a direction that is beneficial for you.
