Should steal-tools be available to install through bower?

disregard, gonna ask in the steal room :)

is stache passes index while iterating over collection or I need to write a helper?
in handlebars I would do this -- tabindex='{{@index}}'
getting NaN with stache
dylanrtt
@dylanrtt
@opolyo01 that should work. perhaps you are iterating over an object instead of a list/array in which case you probably want @key
opolyo01
@opolyo01
nope {{#dimensionList}} .. {{/dimensionList}}
dimensionList --> Array
is it even documented anywhere? http://canjs.com/docs/can.stache.html
dylanrtt
@dylanrtt
yep http://canjs.com/docs/can.stache.helpers.index.html
I am fiddling with it now and it seems that sometimes I do also get NaN
Chris Gomez
@akagomez
@opolyo01 I can get it to work with the {{#each}}helper: http://jsbin.com/warebexisa/edit?html,js,output
opolyo01
@opolyo01
yep, each works
dylanrtt
@dylanrtt
oh right, I think it is only supposed to work with #each, not with {{#list}}{{/list}}
opolyo01
@opolyo01
ok now please remind me the difference of each vs {{#list}}.. I remember one of them is less efficient
Chris Gomez
@akagomez
I tend to steer clear of the {{#block}} helper anyway. It re-renders the entire list on change vs the {{#each}} helper which makes the fewest # of DOM manipulations necessary for each add or remove.

Where is the best place to put animation type code, like sweeping-in, rolling-out type stuff, in a can-component? The viewModel seems the wrong place. The Events object also seems wrong... so what is the right place? (the-can-way)
dylanrtt
@dylanrtt
@BigAB the can.view.attr page shows making a fade-in-when="{prop}" attribute. you could probably apply the same principle to other animations

Anyone know the best way to solve this in CanJS? I have multiple components that all need the same function - isLoggedIn() for example. Right now I've needed to copy that function into every component which feels very wrong. My gut reaction was to put that in my main component assuming it acts as a parent to all other components and assuming child components inherit from the parent. But I'm pretty sure those assumptions are not correct. Any tips on how to correctly do this is much appreciated!
dylanrtt
@dylanrtt
@neelbhat88 your child components will inherit their parent scopes by default unless you set leakScope: false in your component definition
a better way, which also works without leaking scope, would be to pass it to the child components
there may also be value in simply extracting the function to an outside service if possible and including it in all of your components that need it
neelbhat88
@neelbhat88
@dylanrtt - Thanks! We haven't set leakScope: false anywhere so let me double check and see why the child was not inheriting from the parent scope. I did just notice that my isLoggedIn was set as a variable on the parent scope and not as a function - maybe that's it? I'll find out. At least knowing that child components should inherit their parent scopes is all I need - I'm sure I'm doing something else wrong then. Thanks again!

Any ideas why partials with can-value inside do re-render as a whole when the bound value is changing?
I'll try to create a fiddle
dylanrtt
@dylanrtt
@mehiel that might be related to #1759
Aggelos Karalias
@mehiel
yes
Aggelos Karalias
@mehiel
I removed the compute wrapping for now in mustache_core.js:391 to make it work.. but this is a brute force workaround that probably breaks lots of other things..
I'll try to dig deeper in that and see if there's a way to make it work as expected with can-value's in there..
Matthew Phillips
@matthewp
can-value is defined in can/view/bindings
i doubt that's related to the bug though

Is it posible to have some part of the template rendered without bindings (so it will speed up the whole thing), where data is actually static. Maybe it is possilbe to declare some attributes as "not bindable" as they are not supposed to change?
Marshall Thompson
@marshallswain
@whitecolor You can try this helper to opt out of live binding for a property: https://gist.github.com/marshallswain/7e07a23971ab70f78a11
Alex
@whitecolor
@marshallswain itresting, I think a like ability should be included in can out of the box.

@opolyo01
I don't see any examples where can.component would be instantiated inside of another can.component. Is it even possible or I have to declare it inside of the template? If it were can.Control inside of can.Component then I would simply instantiate new MyControl("#selectorId", {})
Alexis Abril
@alexisabril
@opolyo01 Yep, you’d want to use it inside a template. In one component’s template it’s common to use other components.

somebody knows how to tell when canjs has rendered everything? i'd like to embed my app in a server-side phantom instance to serve indexable content. i chose amd over stealjs.
David Luecke
@daffl
CanJS renders synchronously so you just need to keep track of all the asynchronous loading you are doing.
2.3.0-pre also supports server side rendering now using https://github.com/canjs/can-ssr

can.param converts nested objects to bracket syntax like country[name] but my backend expects them to be like country.name in the query string. Is there an easy way to do that so it applies to all requests? should I just overwrite it?
