Both {{#foo}} and {{> foo}} are handled as follows:
- foo may be a template or a function returning a template
- if there are only keyword arguments, they are used to create a data context object (e.g. `x=1 y=2` becomes `{x:1, y:2}`)
- if there are any positional arguments, the arguments are treated as a nested helper call, meaning that the first one will be called on the rest (including keyword arguments) if it is a function
Rendering-wise, the template should only be re-rendered if foo is a function and it is invalidated to return a different value (though the "isolate" that would compare the new value to the old is not on this branch at the moment).
This change also makes the built-in block helpers (#if, #each, etc.) be functions (render macros) instead of components (though #each is still implemented with a component). This avoids data context issues with #if and #unless (the new calling convention isn't really designed to support making something like #if). It also should make generated code cleaner to call `UI.If` instead of including it as a component.
Meteor
Meteor is an ultra-simple environment for building modern web applications.
With Meteor you write apps:
- in pure Javascript
- that send data over the wire, rather than HTML
- using your choice of popular open-source libraries
Documentation is available at http://docs.meteor.com/
Quick Start
Install Meteor:
curl https://install.meteor.com | /bin/sh
Create a project:
meteor create try-meteor
Run it:
cd try-meteor
meteor
Deploy it to the world, for free:
meteor deploy try-meteor.meteor.com
Slow Start (for developers)
If you want to run on the bleeding edge, or help develop Meteor, you can run Meteor directly from a git checkout.
git clone git://github.com/meteor/meteor.git
cd meteor
If you're the sort of person who likes to build everything from scratch, you can build all the Meteor dependencies (node.js, npm, mongodb, etc) with the provided script. This requires git, a C and C++ compiler, autotools, and scons. If you do not run this script, Meteor will automatically download pre-compiled binaries when you first run it.
# OPTIONAL
./scripts/generate-dev-bundle.sh
Now you can run meteor directly from the checkout (if you did not build the dependency bundle above, this will take a few moments to download a pre-build version).
./meteor --help
From your checkout, you can read the docs locally. The /docs directory is a
meteor application, so simply change into the /docs directory and launch
the app:
cd docs/
../meteor
You'll then be able to read the docs locally in your browser at
http://localhost:3000/
Note that if you run Meteor from a git checkout, you cannot pin apps to specific
Meteor releases or run using different Meteor releases using --release.
Uninstalling Meteor
Aside from a short launcher shell script, Meteor installs itself inside your home directory. To uninstall Meteor, run:
rm -rf ~/.meteor/
sudo rm /usr/local/bin/meteor
