We are living in a web world.
Thanks to mobile phones, tablets and more mobile platforms, we are spending more and more time away from our usual workplace, and this brings with it some significant problems for developers.
Thanks to the adoption of open source by major companies, and it being the up and coming the standard, collaboration over great distances have become increasingly common.
Introducing: Codenvy. Codenvy is everything you expect from an IDE, but in a browser. It looks beautiful, supports many many many languages, has built in docker, Git and Subversion support built in, and of course holds your projects. So what does Codenvy look like? Almost all IDE’s have the same look and feel, and Codenvy is no different. @kmoughon - Hi, thanks for the detailed issue. First, there is a separation between the proxy settings for the workspace itself (which are set within a Codenvy configuration property), and those used by maven. What is Codenvy? It's a question we get from developers, ISVs, and enterprises. Now that we are a commercial entity focused on cloud IDEs, we produced this n.
Read writing about Ide in Codenvy Blog. Codenvy Blog — cloud workspaces for development teams. Develop code with portable Docker runtimes. Workspaces “dev mode” production adding intellisense, debuggers and desktop sync. Create teams for sharing at codenvy.io or in a private install. Create workspaces with production runtimes containing your projects and tools.
So what are developers currently doing as their workflow, and workspace?
Putting aside practices such agile development, a developers workflow looks like this:
Sit behind a computer, fire up Sublime/PyCharm, make some code changes, push this upstream on GitHub (or similar), merge it with changes from others, and release.
Works fine, but when you are away from the office, and unless you carry your laptop everywhere you go (yes, I’m guilty of that), you can’t make changes, however critical.
But wouldn’t it sound quite normal if someone came up with a way to develop on the web, and I don’t just mean like changes.
Like the whole development process?
Well, someone did, and they did it perfectly!
Codenvy is everything you expect from an IDE, but in a browser.
It looks beautiful, supports many many many languages, has built in docker, Git and Subversion support built in, and of course holds your projects.
So what does Codenvy look like?
Almost all IDE’s have the same look and feel, and Codenvy is no different.
That’s not a bad thing though, as you can simply open it and work, since you already know where everything is.
It has a beautiful dark theme which looks superb, has syntax highlighting and feels like a native application.
Just have a look at this:
Python support is built in.
But I tend to be rather cynical when an IDE claims to have Python support, since what they usually mean is that they allow you to write Python with bare minimum support.
But Codenvy delivered.
They support Python 2.7 & Python 3.4 (at the time of writing this).
But they also go into more depth than that.
When selecting your programming language, the bottom of the list provides a standard Python 2.7/3.4 setup, Python 2.7 Web and Python 2.7 Google App Engine Guestbook.
Selecting for instance Python 2.7 will give you what the image above shows.
A ready to go boilerplate Flask setup.
No need to install the dependencies, and you don’t even need to remember how to create the app. It’s all ready to go.
And as you can see, syntax highlighting is working excellent.
But there is one feature that is sadly lacking: code completion.
Whilst coding, you won’t find the editor giving you tips on which function you might be trying to use.
This means you have to code everything by hand, every single letter. That’s a real shame.
Git and Subversion
I am not a user of Subversion, but needless to say, that is also supported.
I’ll be looking at Git integration though.
When starting a project, you can just pull in code from a Git repository, or GitHub.
As you can see below, it’s a very simple process:
But you could also write code from scratch and simply host it with Git using Codenvy.
Selecting Git from the top menu, and then Initialize Repository will connect it to git where a Git repo URL is created ready for you to do all your Git magic with.
But before you ask about BitBucket, yes, that too is integrated!
No IDE is complete without customization (at least to some degree).
And whilst I did not expect it from a web app, it is available.
As you see in the screenshots above, the standard style is a dark colour editor.
But selecting ‘Window’ and then Preferences, brings the following options:
I found it unable to change from Dark Theme however.
But the codenvy blog posts, and posts from others suggest that it is possible, so this may be due to my free account.
You are also able to change to a VIM like editor (sorry, I’m not a VIM fan).
So for a web app, customization is quite surprising.
But what about working together on a project?
Codenvy makes it unbelievably simple.
You can create a link for any person to get their own copy of the project in a Codenvy instance so they can test the code, contribute to it, and send a pull request. Without having to download a single thing!
But rather than me explain it, look at this video to see how it’s done:
So is Codenvy worth looking at?
If you are an avid programmer, contribute to projects and use services like GitHub, this is an absolute yes!
But even if you are a single developer who is used to working alone, it’s still such a delightful IDE to use. And they make full use of Docker which is just excellent.
But if you are a beginner just looking at starting programming, then you may find traditional IDE’s better with their code completion.
* Excellent Python support
* Integration with GitHub/BitBucket
* Syntax Highlighting
* Fully fledged IDE
* Great documentation
* Support for Eclipse
* No code completion
I recommend to try it out, and let me know what you think!
You can create new assemblies (binaries) for Codenvy. An assembly can contain Eclipse Che extensions, custom stacks, and templates that appear in the dashboard and IDE. You create the binary from Codenvy source code and then use the embedded Puppet system to update Codenvy with your new binary. Your binary can optionally include Eclipse Che extensions. Eclipse Che extensions can be created as part of your Codenvy project, or previously compiled and uploaded to maven.
Codenvy runs as a set of distributed Docker containers. The core runtime is a Codenvy server that runs on a Tomcat instance in the Docker container. This process shows you how to build a new set of binaries for deployment into Tomcat and then how to restart Codenvy’s distributed services to make use of your new binary.
You will need to have a valid Eclipse Che development environment setup, which requires Java and Maven installed in order to build assemblies.
Get the Codenvy source code repository and checkout the proper version that you would like to base your assembly off of.
Select the version on which perform the change. For example for a custom 5.0.0 version
shell$ git checkout -b custom-assembly 5.0.0
You can now make source code changes to resource files to change the branding. Or, if you want to add or remove different Eclipse Che plugins, you will modify Codenvy’s dependency and assembly files.
For example, let’s remove the Node.JS GDB debugger from Codenvy.
In this folder, you will add or remove dependencies from the
<plugins> section of
pom.xml and edit ` src/main/resources/com/codenvy/ide/IDE.gwt.xml `to add or remove plug-ins from the IDE itself.
Codenvy Ide Java
In the example, let remove nodejs gdb debugger dependenvy from
pom.xml and remove NodeJS debugger from
IDE.gwt.xml file. Here is diff output of both files:
You will use the Codenvy CLI as you normally would with a single additional. Add a single volume mount to
:/repo that contains the path to where the Codenvy git repo resides. When you start Codenvy with this extra volume mount, the CLI will look inside the repo for a built assembly and use its binaries instead of those included within the Docker image.
You can create bundles that include your own Eclipse Che extensions, stacks and templates. You will need to have build those extensions and compiled them into JAR and ZIP files. Eclipse Che has docs for writing extensions and customizing stacks.
Maven’s default enforcement rules require that every extension that you add be listed as a dependency in Codenvy’s parent
pom.xml. You can skip enforcement by using
-Denforcer.skip=true argument when performing a
mvn clean install.
Beyond this mandatory requirement, you may have to add your dependencies to additional locations depending upon the type of extension that you are adding (server-side, workspace extension, IDE extensions).
First, add the dependency in the
<dependencyManagement> section of Codenvy’s parent
pom.xml located in the root of the repostiory: Fern haworth chair.
After adding a dependency, you need to sort maven with
mvn sortpom:sort. You do not have to provide the
<version> tag. Maven will pull the version of your extension that matches the version of Codenvy.
Second, if your extension is an IDE extension, add your extension as a dependency to the IDE:
Third, if your extension is a server-side workspace extension, add your extension as a dependency to the workspace master:
If you deployed your server-side extension as a REST service, it will then be available at
Fourth, if your extension is a server-side workspace agent extension, which is designed to run inside workspaces, then add your extension as a dependency to the workspace agent:
