Enso Language Support for VSCode
Downloading
Enso Tools for VSCode is available from VSCode marketplace. Simply install it from there.
It is possible to download the latest development version of the "VSCode
Extension" artifact from the
latest actions run.
After downloading the ZIP file unzip a .vsix from it and install the .vsix
file into VSCode.
Your Enso files will get proper syntax coloring. You'll be able to debug Java/Enso code interchangeably.
After installing the Enso .vsix file (and reloading window) we can find
following two extensions in the system:
Using & Debugging
Once installation is over let's continue with choosing File/Open Folder... and opening root of Enso Git Repository (presumably already built with sbt buildEngineDistribution). Following set of projects is opened and ready for use:
With the workspace opened, you can open any Enso or Java file. Let's open for
example Vector_Spec.enso - a set of unit tests for Vector - a core class of
Enso standard library:
It is now possible to place breakpoints into the Vector_Spec.enso file. Let's
place one on line 120:
Let's do a bit of debugging. Select "Listen to 5005" debug configuration:
And then just execute the engine distribution in debug mode:
sbt:enso> runEngineDistribution --debug --run test/Base_Tests/src/Data/Vector_Spec.enso
After a while the breakpoint is hit and one can inspect variables, step over the statements and more...
...as one can seamlessly switch to debugging on the Enso interpreter itself! One
can place breakpoint into Java class like PanicException.java and continue
debugging with F5:
Should one ever want to jump back from Java to Enso one can use the "Pause in
GraalVM Script" action. Select it and continue with F5 - as soon as the code
reaches a statement in Enso, it stops:

Building VSCode Extension
To build this VSCode extension and obtain Enso syntax coloring as well as
support for editing and debugging of engine/runtime sources in VSCode:
enso/tools/enso4igv$ mvn clean install -Pvsix
enso/tools/enso4igv$ ls *.vsix
enso4vscode-*.vsix
one needs to have npm, Java and mvn available to successfully build the
VSCode extension.
Once the .vsix file is created, it can be installed into VSCode. Select
Extension perspective and choose Install from VSIX... menu item.
Reference
There are extensions for NetBeans and also for IGV. Read more here.
