@finlay

I wonder how I can reference them ?

Nokome Bentley

@nokome

Yes, when we populate the database we create (hopefully) easier names

Let me just get my local version running again....and I'll give more info

Finlay Thompson

@finlay

So, how can I find the haskellPackages.xeno package...

It is there

Finlay Thompson

@finlay

poping out to get some lunch

Nokome Bentley

@nokome

OK, looks like we need to do something special for haskell packages...like this....

https://github.com/stencila/nixster/blob/master/src/nix.ts#L89

Finlay Thompson

@finlay

Yes! That is what it needs

Nokome Bentley

@nokome

I've just done that, and it's currently building on Travis:

nixster search 'xml' --type haskell-package
    haskell-aws-sdk-xml-unordered  0.3.1      The xml parser for aws-sdk package
    haskell-berkeleydbxml          0.7.2      Berkeley DB XML binding
    haskell-blastxml               0.3.2      Library for reading Blast XML output
    haskell-data-stm32             0.1.0.0    ARM SVD and CubeMX XML parser and pretty printer for STM32…
    haskell-dom-selector           0.2.0.1    DOM traversal by CSS selectors for xml-conduit package
    haskell-dtd-text               0.1.2.0    Parse and render XML DTDs
    haskell-dtd-types              0.3.0.1    Basic types for representing XML DTDs

@finlay

perfect

Nokome Bentley

@nokome

Check the releases page in a minute or two for the new binary

Finlay Thompson

@finlay

stencila/nixster#47

I just added an issue to close, when I have tested it

Nokome Bentley

@nokome

Great, thanks

Finlay Thompson

@finlay

I am going into a couple of hours of meetings nowish, so I'll be back to try this later...

@nokome thanks for your help...

I feel a blog post coming on...

Nokome Bentley

@nokome

OK, thanks Finlay!

Finlay Thompson

@finlay

Back again....

Nokome Bentley

@nokome

:wave:

Finlay Thompson

@finlay

Trying to find the haskell libraries ?

yeah, works!

nixster create readxml --adds haskell-xeno --adds haskell-cabal-install --adds haskell-cassava

Nokome Bentley

@nokome

Does that work? Is it not nixster create readxml --adds haskell-xeno haskell-cabal-install haskell-cassava

In any case editing the YAML is probably easiest once it is created

Finlay Thompson

@finlay

It does something

Couple of questions before I run off:

When you do nixster --pure=false enter, it doesn't copy environment in

For example there is no $HOME

Nokome Bentley

@nokome

Correct

(I think)

Finlay Thompson

@finlay

I thing nix-shell copies some of the environment into the new shell

Are you relying on the nix-shell command, or are you doing it some other way ?

The other question relates to this error:

finlay@kahu:readxml[master*]$ nixster create readxml --adds haskell-xeno --adds haskell-cabal-install --adds haskell-base
💣  Environment "readxml" already exists, use the 'force' option to overwrite it.
finlay@kahu:readxml[master*]$ nixster create readxml --adds haskell-xeno --adds haskell-cabal-install --adds haskell-base --force
error: Package ‘base-4.12.0.0’ in /nix/store/i8ghkgzflqpwfaq5yk3hmrgvq2g038dr-nixexprs.tar.xz/pkgs/development/haskell-modules/hackage-packages.nix:35183 is marked as broken, refusing to evaluate.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowBroken = true; }
to ~/.config/nixpkgs/config.nix.

(use '--show-trace' to show detailed location information)

Nokome Bentley

@nokome

Some other way - just starting bash

Finlay Thompson

@finlay

I think the nix-shell does a selective copy of some environment variables...

Nokome Bentley

@nokome

Do you think that we should inherit the current env when pure=false?

Finlay Thompson

@finlay

I think some of at least

It would be good to do what nix-shell does

or even use nix-shell

I'll go have a look at the code...

Nokome Bentley

@nokome

I'm really not sure about the error: Package ‘base-4.12.0.0’ ... . Trying the

  { allowBroken = true; }
to ~/.config/nixpkgs/config.nix.

is probably best first option

Finlay Thompson

@finlay

yeah

That helped

Oh, I really have to head off, wish I could spend more time on this...

Finlay Thompson

@finlay

I'll be back!
