electron app not working with V2

[hedefalk]

I'm trying to run desktop version in V2 branch. I've been using the Electron based app a lot since it's the only way I've been able to do node/npm based development.

Expected Behavior

That the Electron apps starts.

Actual Behavior

White screen with the following error:

module.js:487 Uncaught Error: Cannot find module '@jscad/array-utils'
    at Module._resolveFilename (module.js:485:15)
    at Function.Module._resolveFilename (/Users/viktor/dev/projects/OpenJSCAD.org/packages/desktop/node_modules/elec…ctron.app/Contents/Resources/electron.asar/common/reset-search-paths.js:35:12)

    at Object.Module._extensions..js (module.js:580:10)
    at Module.load (module.js:503:32)

Steps to Reproduce the Problem

1. git checkout V2
2. yarn desktop

Specifications

• Version: V2 branch
• Platform: Mac
• Environment: node.js/electron

Is there some version I can run? I accidentally checked out origin/V2 right now and kindof lost track where I was before. @kaosat-dev, I know you helped me with this before.

Basically I've been using the the Electron version just as an app by running npm run desktop and I've been doing my designs as node modules. Every once in a while something weird happens and the app hangs though. That just happened and therefore I checked out origin/V2. Unfortunately I lost track of what branch I was using before that was somewhat working so now I'm entirely lost right now :/

Thanks for an awesome project!

Ouch, ok, desktop ignored from bootstrap:

--ignore @jscad/desktop

Man, that was confusing. 'Cos I was trying it out running npm install inside the package first, but then added deps and nothing happened on lerna bootstrap…

[hedefalk]

I started doing some superficial changes to try to make the electron app start but I'm beginning to realize that there might be a deeper reason this is left unfixed…?

Is there a branch that is more up to date than master but still have a working electron app?

[z3dev]

I’ll have to check... but V1 (master branch) should be working.

Or do you want to work with V2? This is now in very early adoption.

[hedefalk]

git fetch
git checkout origin/master
git clean -f -d -X
rm -rf ~/Library/Application\ Support/@jscad/
nvm use 10 // dunno  about that, but had issues with 13 I think?
npm run desktop

Desktop app starts! But loading my design gives me:

Error: Uncaught Error: Bad output from script: expected CSG/CAG objects line: 54, filename:file:///Users/viktor/dev/projects/OpenJSCAD-3/packages/desktop/src/core/code-evaluation/rebuildSolidsWorker.js stack: undefined

Which was the reason I started exploring V2 branch.

I'd love to work with V2. I see that vtree is integrated into main repo there which would be nice. I'm currently using https://github.com/kaosat-dev/jscad-tree-experiments as described here:

https://github.com/jscad/OpenJSCAD.org/blob/master/packages/desktop/README.md#how-to-use-it--temporary-instructions

I see these instructions have changed in V2 to use internal vtree deps

[z3dev]

Hmm... please return only CSG or CAG objects from your main() function. There might be some else.

I’m trying to enable the desktop application with V2 now. It’s taking a while as there are still lots of dependencies to update, and some code changes. I’ll let you know when it becomes available again.

[hedefalk]

Awesome! Thank you so much for looking into it. I tried myself, but felt I didn't really know what I was doing ;)

OK. I gave it my best shot but the desktop application is going to need a total rework, which @kaosat-dev can only handle.

@hedefalk what other options do you have?

[hedefalk]

@z3dev Thanks a lot for giving it a shot!

I've been able to manage running from master up til now. Every once in a while I seem to get into a weird state and I'm not sure what I've done to escape from it but so far I've been able to manage. I've done things as clear the cache and re-checking the "experimental geometry caching see" toggle…

Wow, it seems I've just got it running again from master :) Happy, happy!

Ok, this seems to be it then, when I get in a bad state, it seems I just need to:

• Quit the app
• clear the cache (/Users/viktor/Library/Application Support/@jscad/desktop)
• start the app
• re-check "experimental geometry caching see"

@z3dev I might have forgotten the fourth step this time. Without that caching I get that mentioned error. It seems I can continue using master! Thanks and sorry for taking your time!
