Re: It's official: mruby-browser is now called WebRuby!

Hey, I'm judofyr.

RubyScript was a (as you said) a weekend hack. I don't think I'll continue developing it. The approach I took (implementing a YARV-interpreter + Ruby-runtime in JS) takes time and I don't really have a use-case for it.

You can have the name if you like.

FYI: "fyr" in Norwegian means "guy" :-)

Re: WikiLeaks offentliggjør liste over strategiske installasjoner

Målet med terrorisme er å skape frykt. Man skaper lite frykt ved å ødelegge strategiske ressurser som man relativt lett gjenoppbygge (vanskeligere å sette opp nye nasjonalsymboler). I tillegg er det mye lettere å beskytte disse målene.

Jeg tviler på at det største problemet for terrorister er å finne mulige mål...

Det kalles "journalistikk".

The funny thing is that if you asked me that question today, I would gladly zip the code and send it to you ;)

Just let me know if you want to have the Webby-source, in case you're wondering how I've set it up.

Re: Magnus Holm - Use the Gemspec

Magnus Holm — Sun, 04 Apr 2010 08:39:44 -0000

Of course, if someone does eval("Gem::Specification.new{ ... }") there's not much we can do, but we can still handle the common case.

Just feed it into a Ruby parser. When it sees "Gem::Specification.new |s|" it knows the s binds to the specification object. When it sees "s.version = '1.0.0'" it knows the version is a literal. When it sees "s.version = Bundler::VERSION" it knows the version is an expression. This will probably work for ~ 99% of all gemspecs.

Re: Magnus Holm - Use the Gemspec

Magnus Holm — Sat, 03 Apr 2010 16:14:06 -0000

I'm an optimist, so I believe this is a perfectly solvable problem. I'll probably give it a try some time.

Re: Magnus Holm - Continue that exception

Magnus Holm — Tue, 19 Jan 2010 02:15:54 -0000

Hammertime was definitely what inspired me to write #continue :-)

Re: Magnus Holm - Temple

Magnus Holm — Fri, 18 Dec 2009 14:07:17 -0000

Defining a method would only work if (a) a few templates are used a lot and/or (b) you can serve different shops on different servers based on which template they use (so you can define a few templates on each server). Probably not worth it though.

Interesting indeed. Do you have any numbers (and want to share them) of how much time rendering takes in Shopify? How do you serialize the templates now? Marshal.dump on the @nodelist? How is performance in 1.9.0 compared with 2.0? This benchmark http://blog.nathanielbibler... shows that Erubis is ~ 100 times faster than Liquid on a simple for-loop, but if it's only a fraction of the total response time, it might not matter so much.

Re: Magnus Holm - Moving to Nginx

Magnus Holm — Fri, 18 Dec 2009 13:53:54 -0000

Yeah, yeah, yeah. It's not my fault Passenger didn't worked with Nginx for a loooooong time. Feel free to upgrade it yourself, if you make sure everything else works too…

Re: Magnus Holm - Temple

Magnus Holm — Tue, 15 Dec 2009 14:07:59 -0000

I disagree.

It can be run through eval, you just have to make sure the user can't put any malicous Ruby in the string. Look at Mustache - it's perfectly safe to let any user edit the mustache-files (aside from the fact that it currently has no protection to {{exit}}, but that's like a two-line patch in context.rb).

Just take the compiled template and store it. It's a string - fits perfect for any DB/cache. I'm pretty sure eval is faster than deserialize + render. As a string, it would also be possible to cache hot templates locally (by defining them as a method).

Oh, and Liquid has a quite simple syntax, but lots of little quirks too. Supports both foo[0] and foo.bar, even though it's not documented anywhere. Why is "nil >= 0 or nil < 0" false? Why are filters checked at render-time, not compile-time? Do you somehow run the same template under different filters? Why do you parse "foo.bar" at render-time too?

Re: Magnus Holm - Parkaby

Magnus Holm — Sun, 05 Jul 2009 12:50:53 -0000

Erector is a lot faster than Tagz, but still far behind Parkaby. How far? Well, it all depends on how deeply you nest your blocks...

Re: Magnus Holm - Parkaby

Magnus Holm — Sun, 05 Jul 2009 12:49:07 -0000

Man, there's so much awesome code hiding in GitHub! You have even implemented indentation and concat_emit_fcalls! I couldn't get it faster than Erubis though, but it's still impressing. I might have to steal some of your code ;)

As for 1.9, thanks to RubyParser it's possible to use Parkaby as long as you store the code in a string/file, so there shouldn't be any problem running it on Rails at least.

Weird. It appears to be a bug in RedCloth which doesn't handle <notextile> properly...

In case you're still in the dark: http://gist.github.com/ is a Pastie-clone powered by Git (developed by the GitHub guys) :-)

Re: Magnus Holm - Copy Folders to a Branch

Magnus Holm — Wed, 04 Feb 2009 16:22:28 -0000

Well, the idea was that branch, push_to, repo and message are settings, and will overwrite the previous value; while directory, file, keep and keep_all are DSL for describing actions (and is stackable).

It does makes sense to alias #branch to #branch= etc. though.

Oh, thanks! Should be fixed now :-)

Good to know (all of the things you mentioned)!

I've updated the post with the correct Sinatra solution and proper credits to Michael Fellinger :-)

Re: stuff - ruby - Case Or Hash

Magnus Holm — Fri, 02 Jan 2009 07:58:04 -0000

If you're really going to use a Hash, why don't just set the default_path as a default?

DOMAIN_MAPPINGS.default = "http://default.com"
...
redirect_to DOMAIN_MAPPINGS[request.domain]

Re: The Exciter - Getting Webby With It

Welcome to the club!

But seriously, why not just write --- in stead of #{'-'*3}? :P

Re: Build your own compiler in Ruby with LLVM - macournoyer's blog

Magnus Holm — Wed, 10 Dec 2008 12:17:24 -0000

Cool stuff. How would you implement a global variable? Now you assign the variables to the block (in a function), can you do something similar but assign it to the module? Or can functions load each others variables/pointers?

Re: Magnus Holm - Building a Website with Webby

Magnus Holm — Mon, 20 Oct 2008 13:06:35 -0000

Yeah, Webby is really cool, even though this writeup is starting to get cold. And your design is really one of those I wish were mine :-)

Re: Magnus Holm - It's a Gash, Gash, Gash

Magnus Holm — Sat, 11 Oct 2008 14:45:32 -0000

Well, I'm using code from git-shelve, so until Michael Siebert changes that license to MIT or allows me to release my, slightly modified, version as MIT there's not much I can do.

I'll send him an email, and we'll see how far we can get :-)
