cannot create a new generator using typescript

[Bertrand Thelen]

Hi,

I just tried to create a new generator for our custom DSL. 

I first followed the "build a custom generator" lab but than tried to move to typescript in order to re-use the code from the existing generators.

After solving all the path or naming issue, I'm stuck with a few errors left on the diascript_generator.ts (pasted below).

Currently it's mostly a mix of the lua and the javascript generator with little to no modification but I can provide the files if needed.

In order to retrieve the variables real names, I suppose that I need the namesDb and given that the names modules (and others in the xxx_generator.ts files) are not exported, I cannot reach them.

The last error is not about a missing dependency but and is rather cryptic to me but I haven't investigated much on that side so far.

Am I doing something wrong? Should I follow another method for custom generators?

Thanks for any advice that could help me unlock that.

Regards,

Bertrand

Hi,

What do your import statements look like? Blockly core itself imports classes and functions by path, but for third parties, the expectation is that you just 

import * as Blockly from 'blockly/core';

once at the top of your file, and then reference types in your code by their fully-qualified name e.g. Blockly.utils.string, or Blockly.inputTypes.STATEMENT or the like. Let me know if that helps or if you're still running into issues!

Was exactly that, thanks for the help

I was using:

```import type {Block} from 'blockly/core/block';
import {CodeGenerator} from 'blockly/core/generator';
import {inputTypes} from 'blockly/core/inputs/input_types';
import {Names, NameType} from 'blockly/core/names';```

and the likes. changing to the fully qualified name from Blockly solved all my issues.

Can't wait to continue to discover Blockly, pretty sure it will respond to a few needs we had for a long time!

Thank you,

Bertrand
