Bash: Git Submodule Foreach?


Answer :

The script passwd to git submodule is run with it's working directory set to the top of the given submodule...so you can simply look at pwd to see if you're in you're in the particular submodule. However, if you take some time to read the git submodule documentation, it turns out to be even easier:

foreach     Evaluates an arbitrary shell command in each checked out submodule. The      command has access to the variables $name, $path, $sha1     and $toplevel: $name is the name of the relevant submodule section in      .gitmodules, $path is the name of the submodule directory     relative to the superproject, $sha1 is the commit as recorded in the superproject,      and $toplevel is the absolute path to the top-level of the superproject.

So you can do something like this:

git submodule foreach '[ "$path" = "Libraries/JSONKit" ] \   && branch=experimental \   || branch=master; git co $branch'

AngularJS $on Event Handler Trigger Order

Answer : Very good question. Event handlers are executed in order of initialization. I haven't really thought about this before, because my handlers never needed to know which one run first, but by the look of you fiddle I can see that the handlers are called in the same order in which they are initialized. In you fiddle you have a controller controllerA which depends on two services, ServiceA and ServiceB : myModule .controller('ControllerA', [ '$scope', '$rootScope', 'ServiceA', 'ServiceB', function($scope, $rootScope, ServiceA, ServiceB) {...} ] ); Both services and the controller define an event listener. Now, all dependencies need to be resolved before being injected, which means that both services will be initialized before being injected into the controller. Thus, handlers defined in the services will be called first, because service factories are initialized before contro...
