Question about coffeescriptredux

[bwiklund]

The coffeescriptredux compiler doesn't seem to support a bunch of coffeescript features. Is it necessary to use this compiler over the official one?

[DavidSouther]

Agree, trying to add instrumentation to a mature codebase is a nightmare - many shorthands aren't compatible, and without a whole-hog switch we'll be running different code in test than in prod.

I'm having issues with this as well. It's a hassle to get my tests to work, seeing as code is running on production just fine, but for tests we need to modify the code that it doesn't support.

I've opened a few issues in CSR - https://github.com/michaelficarra/CoffeeScriptRedux/issues?direction=desc&sort=updated&state=open

Comment on those, and add more of your own?

[michaelowens]

Mine are mainly CS 1.7+ related, which already exists as an issue: https://github.com/michaelficarra/CoffeeScriptRedux/issues/279

But that's 4 months old already with no sign of progress at all.

[jonchay]

This is an issue for me as well. I can't afford to be writing code that satisfies two compilers. Any progress on this? Or at least a reason why you chose to use coffeescriptredux?

[michaelowens]

This will be a lost cause as we can't count on CoffeeScriptRedux. I've tried asking for updates on CS 1.7 features here: https://github.com/michaelficarra/CoffeeScriptRedux/issues/279

But they never responded. All tickets are only responded to by users, not the original creator.

@michaelowens thanks for trying!

[DavidSouther]

I've grudgingly came to the same conclusion. Really too bad boy ibrik. On Sep 12, 2014 3:23 AM, "Jonathan Chay" notifications@github.com wrote:

You guys know that you can submit PRs, right?

[Constellation]

Oops. Sorry for my further late reply. I had no time to do since I need to create my research prototype...

To touch JS AST. By doing so, we can leverage istanbul.

@michaelficarra: Is this problem simply solved by updating ibrik dependency to the latest CSR? I'm not a well-expertised CoffeeScript engineer, so I'm not sure which functionality lacks in CSR... If you need my help to implement something in CSR, please feel free to tell me :)

[vendethiel]

Stuff missing in CSR is mostly ... Rewriter abuses and super, I think

@Constellation:

Nope, CSR is now mostly incompatible with standard coffee. THIS COMPILER IS BROKEN, period.

I'm not a well-expertised CoffeeScript engineer, so I'm not sure which functionality lacks in CSR...

(also answering @Nami-Doc) CSR has very different handling of aliases, sugarisation, indentation, this, super, for loops, and classes. Code generation is also quite different. This is the consequence of the lack of specificication of the language itself. The CSR effort was vain without the support of the main coffee project, we should move on and stand to standard and reference technologies, not partial and exotic implementations (IE6 anyone ?).

Also, CSR has numberous compiler bugs that coffee hasn't. This is mostly a maturity issue as CSR has a real compiler architecture when coffee is in fact quite a hack, but the fact that the project is abandoned before being mature enough makes Ibrik unusable, unreliable, and a serious doubt for the seriousness of Ibrik itself as no serious project will be able to make code coverage in theses conditions.

@Constellation, you should consider seriously to change your compiler dependency. You will see that many forks sole existence is in fact related to this issue (and shame on them to not back-contributing). I offer my help if you want, it's a serious issue.

+1. Please switch to standard CS.

[grahaml]

+1 - like most others here I would love to use this tool, but I'm not interested in using different compilers for prod and testing, or changing my code base to adhere to CSR, which is lesser known and lesser used that the original CS compiler.

[scotdalton]

:+1: for switching to standard CS

[bloo]

+1 for standard CS - hoping to see PR #25 in master soon

[Constellation]

Merged. And published ibrik as 2.0.0 :)

[mackwic]

Congrats @Constellation , @scotdalton and @jstamerj ! And thanks ! :smile:

[michaelowens]

This is great! Thanks and well done guys!

[Constellation]

Thanks all and super thanks to @scotdalton and @jstamerj !!!
