Debugging TypeScript

[angelozerr]

typescript.java uses JSDT Editor for the *.ts file. So It should be cool if we could debug TypeScript like TypEcs with:

• Webclipse, see https://www.genuitec.com/forums/topic/debugging-typescript/
• JSDT debugger, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=487465

@angelozerr we have the support scheduled for upcoming release. I will ensure that breakpoints work with your editor as well, for web and nodejs debugging. Is there any other target for TypeScript debugging?

[piotrtomiak]

@angelozerr do you have any update site from which I could install your TypeScript plugins? If I am correct and the files are opened in a regular JSDT editor, there should be no problem with putting breakpoints.

[angelozerr]

@piotrtomiak please read https://github.com/angelozerr/typescript.java/wiki/Installation-Update-Site but it's not finished.

[piotrtomiak]

Yeah, the update-site is not working. I've checked out projects from git and it works. We are going to release source map support in 1-2 weeks. To get workspace mapping working, you will need to setup sourceRoot property correctly:

{
  "compilerOptions": {
      "target": "es5",
      "outDir": "target/js-build",
      "sourceMap": true,
      "sourceRoot": "workspace:test/src/main/typescript"
  },
  "files": [
      "src/main/typescript/demo.ts"
  ]
}

[angelozerr]

Yeah, the update-site is not working.

To be honnest with you, I have done that quicly without testing it. I have created the issue
#7

We are going to release source map support in 1-2 weeks.

Very cool!

To get workspace mapping working, you will need to setup sourceRoot property correctly:

Is it a standard tsconfig.json property?

[piotrtomiak]

Is it a standard tsconfig.json property?

Yes. There are several ways to get this working depending on where you keep sources and whether you use Externally Launched Web app or JEE Web App launching. There'll be a FAQ on that, so no worries :)

[angelozerr]

Thanks @piotrtomiak I'm a little exciting to play with your debugger :)

[piotrtomiak]

@angelozerr Webclipse 2016 CI 1 release contains the updated debugger, which has in-built support for source maps. It supports your TypeScript editor as well. Please refer to FAQ: https://www.genuitec.com/tech/javascript-debugging-with-source-maps/ on how to configure your project to have the best experience with source maps.

Please let me know what do you think about the support!

[angelozerr]

@piotrtomiak I will test your work, but I don't know if it will work since now I have a custom TypeScriptEditor (not JSDT JavaEditor)

[piotrtomiak]

Yes, it won't work. I'll look it on Monday.

[angelozerr]

Argh -( sorry with this changes. Now I will not change TypeScript editor since I have a very well performance (because I don't create a JSDT DOM AST).

[piotrtomiak]

No problem, shouldn't be a big deal. Would you be able to create a snapshot build with the editor, so that I don't have to configure TypeScript.java build environment?

[angelozerr]

Hi @piotrtomiak the update site https://github.com/angelozerr/typescript.java/wiki/Installation-Update-Site shoudl work.

[piotrtomiak]

Great, thanks!

[angelozerr]

Your are welcome. Just for your information, I have started to fill wiki to show implemented features of TypeScript Editor at https://github.com/angelozerr/typescript.java/wiki/Editor-Features (it's not finished).

I will implement soon "Compilation" feature (like "compilation on save) and after I will create a release. Hope MyEclipse will be interested with typescript.java
