comby-wrapper v2.1.0

Comby Wrapper

Wrapper around Comby. Comby is a tool for searching and changing code structure

Quckstart

1) Install Comby Server

git clone https://github.com/obenjiro/comby-server.git
cd comby-server
docker-compose up

2) Install comby-wrapper and rambdax

npm i comby-wrapper, rambdax

3) Create script file (script.js) and import comby-wrapper and install functional helper lib (I recommend you to use rambdax)

const CW = require('comby-wrapper');
const R = require('rambdax');

4) Write other code for the script file (script.js)

async function main() {
    const files = await CW.getFiles(["./react_app/**/*.js"], {
        ignore: ['**/node_modules/**']
    });

    await R.pipedAsync(
        files,
        // query
        CW.match(`const :[[cname]] = props => {:[hole]}`),
        // here we preparing replacments
        CW.replaceWithSmartIndent(`class :[[cname]] extends React.Component {
            render() {
                const props = this.props;
                :[hole]
            }
        }`),
        // this command is applying all the replacments in original files
        CW.flushWith(CW.flushInPlace) 
    )
}
main();

5) Run script

node script.js

# or if you want to see progress bar
PROGRESS=1 node script.js
