mustache/mustache

Logic-less Ruby templates.

Łukasz Strzebińczyk

@lstrzebinczyk

Template#tags, Template#sections, Template#partials and Template.recursor

those all look like they are from previous incarnation of parsing code, and are long forgotten

those are related to this:

mustache/mustache#134

@lstrzebinczyk

ah, I see

ok, thanks

I took some time to implement mustache rendering engine as I saw fit. It does not use any metaprogramming at all, any complex template analisis, and I believe the code is much simpler and easier to follow. I cover all features mentioned at http://mustache.github.io/mustache.5.html except

lambdas, because I don't see the point of that
setting delimeter, again because I don't see the point of that
partials, because their implementation will depend on your answer to this message.

Everything else is probably covered and is from 15 to 30 times faster than current mustache/mustache repository.
For now it covers the

Beard.render(template, data)

API, where data is a hash or Beard::View object.

You can find the benchmarks at https://github.com/KillaPL/beard_vs_mustache and run them yourselves.
You can find the code at https://github.com/KillaPL/beard.

I would be happy if you guys could take a look and let me know if you'd be interested in merging this solution into canonical mustache (after it's polished and prepared, of course).

@lstrzebinczyk

I now see that I sort of misunderstood lambdas, I can of course implement this

Łukasz Strzebińczyk

@lstrzebinczyk

I added context lookup, I noticed it was missing. Still 12.7 to 30 times faster : )

@bobthecow

@KillaPL Nice! How's it do against the spec?

Łukasz Strzebińczyk

@lstrzebinczyk

So far I support everything except lambdas, partials and delimeter setting

I will probably add lambdas and delimeter setting tomorrow

and partials when Beard's future is decided, either integrate with Mustache or write something simple from scratch

Łukasz Strzebińczyk

@lstrzebinczyk

Ah, sorry, I also don't support setting unescaped values with {{&

but that is, like, a 15 minutes of work

Hugo Peixoto

@hugopeixoto

you should probably integrate the spec tests into your repository

@KillaPL hey, I'm been thinking about KillaPL/beard and while I appreciate your contributions I think you'd do best developing it independently

and then when it passes the spec you can add it to the list of available implementations

it's just too big a change and I think there's some value in a clean room implementation alternative

Łukasz Strzebińczyk

@lstrzebinczyk

Hi. This was one of the ideas I came up with. I have some more work to do with my day job and Beard is standing in place, It will have to wait some time.

I also might have some comments to the spec itself, the spec tests seem to assume the implementation take care of whitespace

but I have to make more of that work first

Ricardo Mendes

@locks

yes, there are some whitespace-related specs

Justin Hileman

@bobthecow

Mostly around “standalone lines”, basically what happens when a line only includes whitespace and a tag that’s not interpolated.

And indenting partials.

@mikehenriquezf

hello guys, how can i make something like this, if i have the data display in <li>?? http://i.imgur.com/hvr38uV.jpg

Justin Hileman

@bobthecow

Can you give us more context?

Mike Henriquez

@mikehenriquezf

i have an array with 10 articles, i want to display them but in the middle of the list i want to display a 300x250 ad

5 articles, Ad, 5 more articles

Justin Hileman

@bobthecow

@mikehenriquezf Is it always 5 / ad / 5?

split your articles list in half (in code, before it goes to the template). Then do {{# first_set }}{{> article }}{{/ first_set }} {{> ad }} {{# second_set }}{{ > article }}{{/ second_set }}

@jakobdo

Can i get this output with mustachejs: https://dpaste.de/itfU ?

Justin Hileman

@bobthecow

You'll need to prepare your data first.

Jakob Damgaard Møller

@jakobdo

So Mustache cant do the "ifchanged" thing?

Justin Hileman

@bobthecow

nope, because that’s logic, and mustache doesn’t logic ;)

Jakob Damgaard Møller

@jakobdo

Thanks.

Frank Pinto

@frankpinto

hello all!

Trying to get rails to use mustache as the templating engine when it generates scaffolds, etc., anybody know how?

google gave me a couple leads but if anybody here's done it before, I'd appreciate the help :)

Ricardo Mendes

@locks

hey @frankpinto, I'm not sure you can?

Richard Doe

@rwd

Is there any way to use Rails fragment caching with Mustache?

Leonardo "Alemax" Fonseca Ferreira

@leonardoalemax

hello guys, i`m trying to render a template like this:
```<div id="{{renderwithmustach}}" ng-click="{{letangularrender}}" > ````

how to not render the angular tag?

just the mustach one?

Justin Hileman

@bobthecow

@leualemax mustache lets you change delimiters to one that doesn't conflict:

{{=<% %>=}}
<div id="<% renderwithmustache %>" ng-click="{{ letangularrender }}">

@Surreal9

Does anyone know why trying to render a variable that contains a url, it hides the "http:" part and only shows "//restoftheurl.com"? even when using triple braces to cancel escaping? ie {{{myUrl}}}

Ricardo Mendes

@locks

@Surreal9 that's the first I've heard of

Selwyn

@Siilwyn

Does anybody know if a npm package exists that let's me pass a partial, views (and data) directory to it and in turn outputs html to a given directory?
