Is there a way of making a custom deploy strategy for capistrano, but without having to bundle it as a gem? I've searched and searched but everyone's examples are packaged as gems.
I just want to stick it in the include path and require it in the Capfile.
Something like this should work:
require 'capistrano/recipes/deploy/strategy/remote_cache'
class InsaneStrategy < Capistrano::Deploy::Strategy::RemoteCache
def copy_repository_cache
do_something()
end
end
set :strategy, InsaneStrategy.new(self)

I am working on building a swift wrapper over a C library (ROS2 RCL), using C interop features. I’m currently using CMake with module maps to achieve this functionality. Currently, my modulemap looks something like this:
module CRcl [system] {
header "/opt/ros/foxy/include/rcl/rcl.h"
link "rcl"
export *
}
This currently builds just fine on my system. However, using the absolute path is a pretty poor solution, as it requires modification for different os’s or custom install paths. I would prefer for it to be automatically discovered.
Ideally, I’d imagine something like this:
module CRcl [system] {
header "rcl/rcl.h"
link "rcl"
export *
}
where I don’t specify an absolute path, instead directing the compiler to find the header via a CLI arg or environment variable.
I have seen various guides for working with frameworks in XCode, but nothing that would be relevant for my setup on Linux. Does anyone know of a way to achieve this functionality?
I have an app in Play 2.6 and Scala and I want to configure all my Action to return Future or not, or i could say, to be Action or Action.async by a config file. So I could configure my entire app to work in production or test environment.
I have no clue how to do that. Hpw can I start to study and implement it?
Thank you
I wonder if you're looking for something like this which would allow you to provide environment specific configuration values? Including how to use those values in your controller
That document also covers how to specify which application.conf to use via the command line.
I want to use HtmlElements with my test-project based on Thucydides framework.
It's not clear where to start and how it can be used.
If I use it as in example in main project README, it does not populate elements without additional magic. Is there any examples or start guides?
You can find required magic in htmlelements-thucydides module. Long story short you just need to use BlockPageObject from the package above instead of PageObject provided by Thucydides. Here is a working example as well.
I'm making an iPhone version of an existing Rails app. I'd like to make the mobile version accessible via a subdomain such as iphone.mysite.com.
I know I can use formats and the respond_to block for individual erb files, such as index.iphone.erb as show here:
Creating an iPhone optimised version of your Rails site using iUI and Rails 2
But I'd like to keep entirely separate view directories for the mobile version and regular version such as this:
app/views/iphone
Here's what I've tried in my Application controller:
class ApplicationController < ActionController::Base
before_filter :set_site
def set_site
subdomain=self.request.subdomains[0]
ActionController::Base.prepend_view_path("app/views/#{subdomain}")
end
When testing this, however, the view switches to the view associated with the last requested subdomain by any user.
For example, if I visit http://iphone.mysite.com, then immediately go to http://www.mysite.com in another separate browser, I see the mobile version instead of the regular one. Refreshing it will correct this and bring up the right version. But if I go back to http://iphone.mysite.com in the other browser and refresh, it brings up the non-mobile site! I'm tearing my hair out and not understanding what's going on.
Any advice would be much appreciated.
Edit 1
Vlad below found a link with a possible solution however it is not working for me. Here is the code I tried. I made a file called subdomain_view.rb and placed it in config/initializers:
# Put all of this in a bootstrap-only initializer
ActionController::Base.class_eval do
APP_ONE_VIEW_PATH = "app/views/iphone"
APP_TWO_VIEW_PATH = "app/views/default"
cattr_accessor :application_view_path
self.view_paths = ["app/views", APP_ONE_VIEW_PATH, APP_TWO_VIEW_PATH]
# This is where you determine the switching mechanism for your application. Here, it is a simple GET parameter.
# You can probably argue that this specific piece SHOULD be in your actual app_controller class definition, as it is the only piece
# of info pertinent to the rest of your application.
before_filter do |controller|
ActionController::Base.application_view_path = request.subdomains[0]=="iphone" ? APP_TWO_VIEW_PATH : APP_ONE_VIEW_PATH
end
end
require 'aquarium'
ActionView::PathSet.class_eval do
include Aquarium::DSL
before :find_template do |join_point, object, *args|
object.each_with_index do |path,i|
object.unshift(object.delete_at(i)) if path.to_s == ActionController::Base.application_view_path
end
end
end
# I'll leave the exercise of testing this or implementing it for your particular app up to you.
With the above code, I am getting the same view no matter what subdomain I put in. Any suggestions on what might be wrong? Am I putting this code in the wrong place?
First, you have an error in your approach. You only 'set' a view path, you don't 'unset' it. When you do something like
ActionController::Base.prepend_view_path
this actually persists between your requests (internally, you are setting a class variable, and because classes are cached in production, this variable remains set between requests). Therefore, the current view path is the view path of your last request.
IMO, you should dynamically compute view_path for your current subdomain (this implies some ActionView hacking). A nice solution is provided here.
I was able to solve the problem by using a gem called themes_for_rails:
https://github.com/lucasefe/themes_for_rails
After installing the gem, here's what I added to my application files:
#application_controller.rb
class ApplicationController < ActionController::Base
theme :theme_resolver
def theme_resolver
current_subdomain=self.request.subdomains[0]
end
end
#routes.rb
MyAppName::Application.routes.draw do
themes_for_rails
end
#Gemfile
gem 'themes_for_rails'
I placed my themes in [application_root]/themes. Make sure you don't put it in [application_root]/app/themes.
I want to include the distance_of_time_in_words method in a sinatra app
I don't want to package and distribute a gem, which is what the Sintra docs direct you to do. I just want that method accessible in my view.
What's the easiest way to do this? Thanks.
On http://www.sinatrarb.com/intro.html look at Helpers section and define helper methods for use in route handlers and templates
Just place the file somewhere in your ruby load path ($LOAD_PATH) and require it. Or place the code directly in your app file.
