Before reporting an error, please read the FAQ and search for the issue in the issue tracker. Also, please don't bump, +1 or "me too" issues. Thank you.
The simplest way to contribute to the plugin is to report issues you encounter in your day to day use.
As a rule of thumb, always keep in mind that we are developers just like you. So, whenever you are going to report an issue, think of how you'd like to receive issues for your projects. Also, we are doing this in our spare time, so the more information we have in the report, the faster we can replicate the problem and get on solving it rather that just doing a bunch of ping-pong in comments trying to extract the needed details from you.
This information applies also when you don't have an error that is caught by the built-in facility but it's something that happens and shouldn't happen (say for example, a formatting issue).
When filing an issue, please answer these questions:
- What version of Go plugin are you using?
- What version of IDEA are you using?
- What version of Java are you using?
- What did you do?
- What did you expect to see?
- What did you see instead?
Also, every time you can, submit the piece of code that's generating the issue. As it might be some proprietary code, take some time and write the smallest code sample that can reproduce it and paste it in the issue (or send it as a link to Go Playground. Screenshots are useful, but, just like you, we can't copy paste code from screenshots either.
Please ensure that the bug is not reported already, this helps us focusing on working on bug fixes not triage work.
If you want to contribute to the code, go to GitHub and check out the latest version and follow the instructions on how to build the plugin from source. After that, you can start picking some pending tasks on the issue tracker.
Make sure you look for issues tags with up for grabs as these are some of the easier ones to get started with.
Contributing to the plugin requires a signed CLA with JetBrains. You can view the steps necessary for this at this page.
Submitting test cases is the next best thing you can do to developing on this project. In fact, you'll actually develop on it since the test code you are going to contribute is still code.
Whenever your time or knowledge allows, submitting good test cases for either for existing issues or for issues that you come across will make a huge difference in the way we spend time to understand the problems and thus solve them.
All code can be checked out from our Github repository in the usual way. That is, clone the repository with HTTPS or SSH:
$ git clone https://github.com/go-lang-plugin-org/go-lang-idea-plugin.git
Cloning into 'go-lang-idea-plugin'...
On Linux/Mac OS X we use gradle as our build system. Gradle is self-installing. This one command
$ ./gradlew buildPlugin
compiles everything, runs the tests, and builds the plugins. The output appears in build/distributions
.
- Download IDEA Community or Ultimate
- Setup the right version of Grammar-Kit
- Make sure that UI Designer and Gradle plugins are turned on
- Checkout plugin repo and open the project
- Open the copy of go-lang-idea-plugin repository (
File | New | Project from Existing Sources...
) with it. Then import Gradle project. The default project module config should work with a recent IDEA 15 version - Git revert changes to the .idea folder because IDEA Gradle import blows it away (https://youtrack.jetbrains.com/issue/IDEA-146295)
- Open
File -> Project Settings
, go to the SDKs entry, click the+
and select JDK 1.6 - Go to the Project entry and make sure that the Project SDK is set to selected SDK
- Wait until the source files of the SDK are indexed
- Run or debug the Go run configuration
If you use Mac, you may check follow path while looking for SDK:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/
/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/
Now you can use the run configurations provided by the plugin source code to run and play.
There are multiple branches of the plugin which correspond to different versions of the IntelliJ Platform:
- 141 -> can be used for IDEA 14.1
- 144 -> can be used for IDEA 16
The master branch will follow the current stable release of IDEA (currently IDEA 15).
Going to Run -> Run...
will provide you with the following run configurations:
Go
will spawn a new IDEA with the latest version of the plugin enabled.All tests
will run all the test cases available in the project. Please make sure that all the test cases pass before committing anything (or making a pull request).Performance tests
will run all performance test cases available in the project.Build plugin
will build plugin distribution archive. All artifacts are stored ingradle/distributions
directory.
You can also have a look at some useful links for getting started with plugin development on IntelliJ IDEA platform.
You might get the following error Unsupported major.minor version 52
in the
logs or the plugin might not work at all.
Check the version of Java your IDE is running on. Since in 99.9% of the cases it will be Java 6, this means that you compiled the plugin with a different version of Java, for example Java 8.
To fix the error, please use Java JDK 6 to compile the plugin and everything should work.
To get the log files, you can go to Help | Show Log in File Manager
and then the
log will be displayed to you.
- Please don't use class comments with information about author or date and time creation.
- Please don't commit anything from
.idea/
directory if you're not very sure what you doing.
We're syncing the plugin source with the Delve debugger.
If you want to customize delve distribution that's used in the plugin you can use -Dorg.gradle.project.customDlvPath
for setting up the path to your local version of dlv.
For further information please see the official plugin development page.
Also, you can read some tips and tricks.
For all development questions and proposals, you can mail to our Open API and Plugin Development forum.
Happy hacking!
