babel config is not loaded.

[krzysztofpniak]

How can I load babel.config.js? I have a code:

const source = "a |> b";

putout(source, {
      plugins: ['remove-unused-variables'],
    });

I got This experimental syntax requires enabling the parser plugin: "pipelineOperator". (1:2)

There is no way to load babel config, anyways everything works good for me https://putout.cloudcmd.io/#/gist/aa57aef60816b5d7875536b9271a701b/73337bbf9ac4cf9df51460ceaa9415ce742a7f19

What version of 🐊Putout are you using?

[krzysztofpniak]

I'm using the latest.

This is not working for me: https://putout.cloudcmd.io/#/gist/790e78f476c01dfe478cf1b8adae54e8/41e70353c72502710d7de340d001ae8cfa142031

export const report = () => `Use 'if condition' instead of 'pipeline operator'`;

export const replace = () => ({
    '__a |> __b |> __c': 'if (__a) __b; else __c;'
});

Yes, this construction is’n supported now in Replacer (good idea for PR to @putout/engine-parser), you can use Traverser instead. What result do you want to achieve: please provide input and output, and I try to help you.

It is easy to enable parsing of pipelineOperator, but what kind of topic to set?

It is also stage-2 so lots things can be changed and it is not supported by any runtime as I know. Are you using pipelineOperator in production and want to get rid of it?

It is also easy to transform such code since this is just BinaryExpression:

Exactly, I'm using pipeline in production for 3 years and I want to get rid of it.

I would like to transform: expr1 |> expr2 |> expr_n to: wrap(expr1).pipe(expr2).pipe(expr_n).value

What kind of topics have you used?

Right now I have an error:

I don't mind to help you converting your codebase, but I need to seed your babel config, and I think is better to add hack:

Also if this is one-time transformation you can update babel parser plugins inside @putout/engine-parser to enable anything you need.

[krzysztofpniak]

I'm using

[
      '@babel/plugin-proposal-pipeline-operator',
      {proposal: 'minimal'},
],

[coderaiser]

Do you need any additional help for this?

[krzysztofpniak]

Yes, I tried Traverser and it gave me the same error.

export const report = () => `replace pipelines`;

export const traverse = ({push}) => ({
  BinaryExpression: path => console.log('path', path),
});

[coderaiser]

Did you update babel plugins?

[krzysztofpniak]

Yes, this construction is’n supported now in Replacer (good idea for PR to @putout/engine-parser), you can use Traverser instead. What result do you want to achieve: please provide input and output, and I try to help you.

You mentioned that it will work in Traverser. However, it seems that manual changes are required in the plugins within the node_modules directory each time, and on every machine I need to use it. Do you have any better ideas on how I can achieve this?

[coderaiser]

https://www.npmjs.com/package/patch-package can help with this, but why don't you want to run transform once and commit to git repository. Do you need to run it every time you write code?

[krzysztofpniak]

patch-packages + change in @putout/engine-parser solves all my issues. Thanks for your help.
