winstanley: An IntelliJ Plug-in for WDL

This plug-in currently supports:

Syntax highlighting
Collapsible code blocks for workflows, tasks, and more.
Highlighting and completion of parentheses () and other braces.
Allows auto-commenting of lines in WDL with CMD+/
Undeclared value detection
"Go to declaration" (currently for declared values only)

More features will be coming soon!

Getting Started

As a Plug-in User

The plugin is now part of the IntelliJ Plugin Repository. To install:

Open the IntelliJ Preferences page
Click on "Plugins"
Click on "Browse Repositories "
Search for and install "Winstanley WDL"

Or, as a Developer

To build or test the plugin using IntelliJ:

Get set up with the pre-requisites listed here: http://www.jetbrains.org/intellij/sdk/docs/tutorials/custom_language_support/prerequisites.html
Create a new IntelliJ project using this repo as the existing source.
Make sure the repo is using the IntelliJ plugin Java SDK
Make sure the repo has a valid Scala SDK attached as a project dependency.

Otherwise you'll see errors like "Cannot find class WdlElementType" even though it's clearly there!

Generate the necessary files (on Mac):

Navigate to Wdl.flex and generate sources using CMD+SHIFT+G.
Navigate to wdl.bnf and generate sources using CMD+SHIFT+G

At this point, you can run or test the project using IntelliJ's preset run modes.

Open the Run Configurations window (for me, in the top right of the IntelliJ window)
Add a new one configuration with the + icon.
Choose the 'Plugin' type. The defaults should be good.
When this new Run Configuration is run, a new IntelliJ window opens with the plugin preinstalled ready for testing.
Additional instructions for setting this up are in the IntelliJ links above.

Errata

The plug-in was created based on the instructions here: http://www.jetbrains.org/intellij/sdk/docs/tutorials/custom_language_support_tutorial.html
