Re: [Nix-dev] reading nix profile derivation priorities from manifest.nix

2014-05-03 Thread Marc Weber 
Excerpts from Rommel Martinez's message of Sat May 03 09:46:00 + 2014:
 Let's presume that I have run the command 'nix-env --set-flag priority ...'
 many times and I have lost track of what they were, how can I reset
 them to the default state?

Following profile links to store, cp -L (dereferencing) them to /tmp and
running diff -r shows:

diff -r 11/manifest.nix 22/manifest.nix
1c1
 [ { meta = { }; name = nvi-1.79; out = { outPath = 
/nix/store/lcb2rbrhb183lbsxhk512d297ymv85j0-nvi-1.79; }; outPath = 
/nix/store/lcb2rbrhb183lbsxhk512d297ymv85j0-nvi-1.79; outputs = [ out ]; 
type = derivation; } ]
\ No newline at end of file
---
 [ { meta = { priority = 20; }; name = nvi-1.79; out = { outPath = 
 /nix/store/lcb2rbrhb183lbsxhk512d297ymv85j0-nvi-1.79; }; outPath = 
 /nix/store/lcb2rbrhb183lbsxhk512d297ymv85j0-nvi-1.79; outputs = [ out ]; 
 system = unknown; type = derivation; } ]
\ No newline at end of file

Thus read ~/.nix-profile/manifest.nix
How to change/reset? Does'nt look like nix-env provides a command (I
might have missed it again).

From buildenv.nix (nix distribution): (d.meta.priority or 5)
thus default priority is 5.

Now from nix-env:
   --meta
   Print all of the meta-attributes of the derivation. This option is 
only available with --xml.

Thus I'd suggest:

nix-env -q --xml --meta

and there it is:

  ?xml version='1.0' encoding='utf-8'?
  items
item attrPath=0 name=nvi-1.79 system=unknown
  meta name=priority type=string value=20 /
/item
  /items

If you want to change something you at least have some pointers where/how to 
get started.

I've changed the subject hoping that its easier for google to find this
post in the future.
