Lix/Lobby

Kevin Leung

@kevinresol

using libs as lix extension seems quite practical

and interesting

Philippe

@elsassph

But I have stated the problem! For a git dependencies, a CLI option to change the branch/version of the dep without having to specify the git URL. I'm not sure how to describe it differently...

Now using a lib itself for that might be a solution. I'll explore that.

Philippe

@elsassph

I'm trying to dev an option in lix client but it's a bit of a hassle to run it locally from source...

lix download / npx lix download sometimes work, sometimes no. Once I got the build to work I tried to use it in another project using npm link and now building doesn't work with a

sh: /Users/philippe.elsass/.nvm/versions/node/v10.15.3/bin/haxe: Permission denied

I'm still probably going to use the run-lib approach eventually but I wanted to try how contributing would look like.

Kevin Leung

@kevinresol

usually I just run the built lix.js directly

sth like /path/lix.client/bin/lix.js build.hxml

Philippe

@elsassph

Ok. I had to npm unlink then npm install lix -g again for things to work

I'll use the direct path instead I guess :D

Philippe

@elsassph

Ok so I have a generic script of what I want:

import sys.io.File;
import sys.FileSystem;
import Sys.*;

class SetVersion {
    static function main()
        switch args() {
            case [name, version]:
                final path = './haxe_libraries/$name.hxml';
                if (!FileSystem.exists(path)) {
                    println('Library $name not found at $path');
                    exit(2);
                }
                final hxml = File.getContent(path);
                final reLib = new EReg('download "([^#]+)#[^"]+"');
                if (reLib.match(hxml)) {
                    final lib = reLib.matched(1);
                    exit(command('lix', ['install', '$lib#$version', 'as', name]));
                } else {
                    println('$path doesn\'t include a recognizable lix download URL pattern');
                    exit(1);
                }
            default:
                println('Name and version required');
                exit(1);
        }
}

Philippe

@elsassph

I would still favor something built in the lix client.

Emugel

@emugel

Philippe, just in case this hasn't been mentionned. Github URLs can be shortened as in ‘lix install gh:username/repo#tag‘, this saves about 19chars compared to the full url.

(In that case maybe it is not that painful, but if it's not github it wont help)

Kevin Leung

@kevinresol

that syntax uses the public http protocol to download a zip file, won't help if one wants to use the git protocol (e.g. for ssh auth, etc)

Philippe

@elsassph

@emugel thanks but our git repos aren't supported by lix

Philippe

@elsassph

Yay, seems to work: https://github.com/elsassph/lix-switch-version

Kevin Leung

@kevinresol

ok this seems to make lix works with Kha:

// khafile.js
function addLixLibrary(name) {
    for (line of require("fs").readFileSync(`haxe_libraries/${name}.hxml`).toString().split("\n"))
        project.addParameter(line);
}

I vaguely remember seeing some haxelib that had some postinstall thing for npm modules... anyone knows some example for this pattern?

I'm trying to keep my projects reproducible, and one more complex part is generating and processing css files. I'm thinking that it could be some separate haxelib that would generate the file based on given configuration, but for that it basically needs to have its own package.json and download npm stuff, etc.

I wonder how to approach it.

Gabriel Hayes

@piboistudios

How do I resolve this issue again? I ran into this in the past and I can't remember what I did to deal with it, think it had to do with some lingering packages...

Error: Cannot find module 'C:\Users\gabri\AppData\Roaming\npm\node_modules\haxeshim\bin\nekoshim.js'

}

(when running haxelib run <haxelib>)

Gabriel Hayes

@piboistudios

Well.. I just reinstalled haxeshim as a workaround but I'm pretty sure you guys deprecated that a long time ago

Can anyone shed light on how to completely remove dependence on haxeshim? I reinstalled Haxe completely and it still seems to be looking for haxeshim when using haxelib

Kevin Leung

@kevinresol

what is your lix version

Kevin Leung

@kevinresol

@back2dos is there a way to print out the path of the haxe folder/binary for current scope?

Kevin Leung

@kevinresol

ok I made this work finally lix run Kha html5

Juraj Kirchheim

@back2dos

\o/

Kevin Leung

@kevinresol

But I still need a easy way to get the path of the Haxe folder, preferably a variable usable in the @run directive

Because kha bundles it's own Haxe binary and I want to override it

Kevin Leung

@kevinresol

and need some way to customize the @run directive

Gabriel Hayes

@piboistudios

@kevinresol Sorry, Lix v is 15.9.1

But its a local install, I don't have a lix globally

Peter Achberger

@Antriel

If I would use postDownload hook to install some node modules into the library folder, is there some way to be able to require them when running node from the project folder?

Juraj Kirchheim

@back2dos

yes, but I wouldn't recommend that ... it's not really in line with how require works

instead, you should use postInstall to install the packages in the project folder

Peter Achberger

@Antriel

Yeah, I did end up deciding to do that. I really hate having node_modules in my Haxe projects, but I can live with that.

Just didn't yet manage to code it. :D The postInstall hook is not easy to test out, hehe.

Just out of curiosity, how could I require them from the project cwd? I.e. how could I find out the haxelib directory?

Hmm. Trying to use --gh-credentials, and it seems to work, as it finds the head commit hash, but doesn't download, just says "Not Found".

Peter Achberger

@Antriel

console.log debugging, it seems to add the credentials headers when looking up the git head, but it doesn't when trying to download the tar.

Kevin Leung

@kevinresol

I think gh-credentials is not preferred as it means that your credentials will be stored in the hxml thus tracked by version control

Peter Achberger

@Antriel

That's fine.

Kevin Leung

@kevinresol

That is not fine. This is the reason why the download url does not contain the credentials

I think it does include it some time in the past

Peter Achberger

@Antriel

I just need something simple that works. Don't wanna mess around with certs and keys and environment variables.

Kevin Leung

@kevinresol

but deliberately removed later

just use git+ssh
