This is an app for creating a repl in node or browser that runs custom cli-style commands. It ships with react bindings.

Run node example

Clone the repo; build with yarn build. Built into the build is a node example. The compiled typescript (javascript) should let you do this:

node dist/testable/node/index.js

A prompt; at which you should type

match scalar -l 1 a hellllllo world -r 1 b hellllllllllo world

Result should look like

{
  'match scalar': [
    { index: 0, match: true, left: 1, right: 1 },
    { index: 1, match: false, left: 'a', right: 'b' },
    {
      index: 2,
      match: false,
      left: 'hellllllo',
      right: 'hellllllllllo'
    },
    { index: 3, match: true, left: 'world', right: 'world' }
  ],
  match: 4
}

Generate and run the react example

This utility also has basic react bindings. Like everything else, these yet lack documentation, but you can easily generate a running example.

Run yarn ts-node examples/browser.ts.

This will create the app in a directory of your prompting.

It will run the app at port 8080, whereon you can run the match scalar example from above.

Build and see browser example (without react)

Run an example by following these steps.

• run yarn add -D react (react is not used in the example; but esbuild requires its installation!)
• run yarn http-server in the terminal at the repo root
• open the browser to localhost:8080
• in the text area, enter e.g. match scalar -l 100 -r 101, a test command
• this should print output, which is the job of this example command
