need to do this at some poin

As currently configured, this derivation wraps psa Node package instead of purescript-psa. The former has nothing to do with PureScript and is not what psa used to refer to in this repository in the past.

This breaks PureScript source code compilation when being used as a build input (I believe that purs detects it and plugs it in in a runtime as its output formatter):

Error: ENOENT: no such file or directory, scandir 'announcements'

    at Object.<anonymous> (/nix/store/nkd3s8hb4ps3q2ch3ljc4jvs2nwy8q0b-psa-1.0.0/lib/node_modules/psa/index.js:33:26)

Running nix-shell shell.nix will fail like this one .e.g. aarch64:

@kritzcreek has made a new version that should fix some hangs.
kritzcreek/pscid@338d7ef

I don't use OSX, but these derivations mostly could depending. There are some isDarwin helpers and such in nixpkgs standard library that you can use for this.

Could be added to build matrix on Travis too.

since my primary usecase is for CI pipelines, would love to see purescript-psa added as I'm using it for catching compiler warnings and turning them into errors

https://github.com/justinwoo/easy-purescript-nix/blob/master/default.nix

Needs { inherit pkgs; } it seems for all of these

probably a good deal of crap to go through, but in short

• use the node environment that is currently generated
• get the actual compiled javascript from the npm tarball, wherever the hell it is, don't build the fucking sources again
• wrapProgram if necessary. probably not.

So what I have been doing is keeping an uncommitted package.json around the folders. For instance this in purs-tidy:

{
  "name": "purs-tidy",
  "version": "0.7.1",
  "dependencies": {
    "purs-tidy": "0.7.1"
  }
}

When I new version comes in, I bump these numbers to match the NPM release. Following this I just run node2nix with the latest node2nix version (Node v12 is deprecated, and node2nix seems to favor the latest maintenance version instead of latest LTS).

After node2nix does it's thing. I run git checkout on the default.nix to keep the modifications Justin did way back when. Then I go back and nvim default.nix and edit the version number to match the package.json and generated code.

I git add *.nix, git commit and write my merge request message, then git push github $BRANCH. The diff this creates is usually minimal which Justin tends to approve of in <48 hours because it's just a few version bumps to read on his end.

I'm new to nix and macOS dev am not sure what to do. I will use a different computer for now.

I think bintray went down.

I upgraded to master and upon running nix-shell I get the error message:

error: value is a function while a set was expected, at `default.nix:8:17`

This refers to the line

  buildInputs = easy-ps.buildInputs;

Full context:

This is my default.nix:

{ pkgs ? import <nixpkgs> {} }:

let
  easy-ps = import ./easy-ps.nix { inherit pkgs; };

in pkgs.stdenv.mkDerivation {
  name = "nerg";
  buildInputs = easy-ps.buildInputs;
}

And this is my easy-ps.nix:

{ pkgs ? import <nixpkgs> {} }:

import (pkgs.fetchFromGitHub {
    owner = "justinwoo";
    repo = "easy-purescript-nix";
    rev = "47507b27e15a9c3b929111cf43d2e9c0e4b97f4c";

@toastal do you happen to know why purescript releases have ncurses problems now?

Bintray, where purty is currently being released, is down and as a result purty was understandably removed from the easy-purescript-nix project (see closed issue #137 and merged PR #139).

I always use purty when writing PureScript because I'm now accustomed to autoformatters like elm-format and eslint. I opened an issue on purty's GitLab repo to perhaps migrate to GitLab's generic repositories so that there would only be a single point of failure for binary upload and source code. Luckily, purty still exists in my binary cache for now.

If anyone is familiar with Bazel+GitLab CI, this could be a solution. It would be a nice re-addition to have purty (regardless of beta-quality) back in the tooling for users.

I'd like to do something like this in a container:

  containers.mypyPurs =
  { autoStart = true;
    privateNetwork = true;
    config = { config, pkgs, ... }: {
      environment.systemPackages = with pkgs; [
        # Shells:
        bash
        # For PureScript:
        # haskellPackages.purescript # using easy-ps instead:
        easy-ps.purs
        easy-ps.spago
        # For mypy/Python
        mypy
        python38Full
        python38Packages.virtualenv
      ];

I was using the described method to define easy-ps: https://github.com/justinwoo/my-blog-posts/blob/master/posts/2018-10-24-using-purescript-easily-with-nix.md#using-this-from-downstream-projects

However, when I try to add to systemPackages as shown, I get an error:

value is a function while a set was expected,

Any suggested workarounds?

I definitely don't want to block this, but importing nixpkgs from the classic file makes stuff like inputs.easy-purescript.inputs.nixpkgs.follows = "nixpkgs"; impossible

Originally posted by @voidus in #134 (comment)

I get the following error when running purs from the 0.14.1 purescript package

Though, the command seems to still work regardless

that'd be great! 🙏

pulp is required to publish packages to Pursuit, right? I'd like to have pulp in my shell.nix.

Following the template of

I have in my shell.nix something like this:

  buildInputs = [
    remote.purs-0_13_8
    remote.psc-package
    remote.spago
    pkgs.nodejs-13_x
    pkgs.nodePackages.bower
    pkgs.nodePackages.pulp
  ];

but nix-shell fails like this while trying to make pulp:

I note that this seems to be doing the wrong thing anyway, it looks like it's trying to build a version of purs which I don't want.

Advice on how to get pulp in my shell.nix? Or how to publish to Pursuit without pulp?

Is it possible to merge #134?

People would like to have multiple versions of purs, spago, etc. exposed. This can be done probably in a simple enough scheme:

purs.nix

->

purs/default.nix (import ./0.13.2.nix)
purs/0.13.2.nix
purs/0.13.0.nix

root default.nix

purs = import ./purs { inherit pkgs; }
purs-0.13.2 = import ./purs/0.13.2.nix { inherit pkgs; }

etc

Currently everything defaults to node-12_x, but we are using 14.x in our project. The pscid/default.nix allows nodejs to be overridden but when easy-purescript is being consumed via buildInputs [ easy-purescript.pscid ], nodejs is not overridable.

add scripts to update packages

e.g. I always add update.sh script to update revision.json/other logic

example https://github.com/srghma/dotfiles/blob/master/nixos/pkgs/dunsted-volume/update.sh

this way I dont need to look for new commit, paste it in nix file, make nix-build, then update expected hash

I just run update.sh and that's all

Why I suggest this:

1. to allewiate steps above
2. there is no info how pscid is generated and how to update it

N.B. it would be good to have some script update-everything.sh that would run all update.sh scripts in repo

hi. I'm new to Purescript so I'm not sure if this makes sense:

cloned the repository
nix-shell ./ci.nix
mkdir test
cd test
pulp init

Error message:
ERROR: No bower executable found.

Pulp no longer bundles Bower. You'll need to install it manually:
npm install -g bower

I was hoping to try out the pulp browserify feature. I don't believe that is in spago yet. If you have a workaround, I will try it.

Hello Justin, perhaps I'm doing something wrong, but I get a hash mismatch when I try to start nix-shell on nixos: 19.09.840.8bf142e001b (Loris)

Any idea please?

I'm new to nix so this may be off base but I think spago has an implicit dependency on git since it will clone dependency repositories for building. I was trying to use this package to write a derivation for a nix project and I kept getting Installation failed. Upon upgrading easy-purescript-nix to the newest version that displays the underlying error, it was because git was missing from the nix-build environment. I think this might be a use case for adding it to propagatedBuildInputs in the derivation, which I understand to be where you put dependencies that aren't required directly but will be needed downstream.

@jmackie could you fix this issue?

I...

• cloned the repository
• nix-shell ./ci.nix
• spago init
• spago test

Got the following

[info] Build succeeded.
/bin/sh: node: command not found
[error] Tests failed: exit code: 127

Adding nodejs to buildInputs seems to fix it.

Are there things missing for a "1.0" tag? If so, they should be listed down here.

Can you please update spago. Current version is 0.7.5.0.

It would be really neat if https://github.com/nwolverson/purescript-language-server would be added. I guess the definition might be similar to other npm based tools.

need to fix .lib references to work with new nix and nixpkgs

somewhere in this body causes all of the derivations to be built it seems, which isn't that slow because we do not allow derivations that try to build from source (this was explained a long time ago by me and can be read in the README)

however, i still do not like wasting disk space and time to build derivations for shit i never want to use

these should be fixed at some point to facilitate nix being able to lazily evaluate instead of having to build all of the derivations.

Hey,

I guess this is more a nix question, how do I update the purs and spago

I tried nix-env -f . -uA spago or nix-env -f . -uA purs-simple, they don't work. I have to nix-env -e purs-simple first, and re-install purs and spago. If there any works to update them ?

Thank you

The purs binary has missing libraries, patchelf should be able to help here
