I found a small example I wrote last year. It shows the ip address of the machine from which the program is running. It does so by calling
http://httpbin.org/ip. This url returns the callers IP address in JSON.
The example shows
get-ing a url and parsing the JSON.
To access the url I'm using
clj-http. This returns a map from which you want the value of :body.
The JSON return value will look like this:
Virtualenv supports the creation of isolated Python environments. This allows you to create your project with all of it's dependencies in one place. Not only does this allow for a simpler deployment path when you release your project but it also makes trying different versions of libraries and experimenting safer.
The following is a good intro for virtualenv.
I stumbled upon this service called Dark Sky the other day which supports an API to return weather reports. I thought it would be interesting to create a small command line application which would query this API and print out a short summary weather report. Yesterday, I took up the challenge to build such an application in Clojure.
The results are up on GitHub in the following repo.
For those who are interested I'll go through a process to build the application.
If you have a GitHub account you are probably aware of gists. Small mini repos which allow you to send links to their content easily. You can create secret and public gists and I've found them to be excellent for sending examples, lists and notes to others in a more contained format than email.
For example, you create a todo list and want to share it with your team. You create a gist of the outline and send everyone the link. The team can all see the outline, add comments and see updates much like a full git repo. All of this without the full setup of a repo.
Now if you use Emacs there is gist mode which makes creating and editing gists even easier.
The mode is available here https://github.com/defunkt/gist.el.
