re-ansi

Ansi code to HTML

Features

re-ansi supports:

• Cursor movement: \n, line erase and \r line erase
• SGR parameter: italic, bold, underline and line-through
• 3/4 bits color code

re-ansi removes styles on new lines, so that a <br /> can't be nested inside <span style> elements.

For details, see the AnsiCode.parse function.

Install

Add to your package.json:

npm install @softwarefactory-project/re-ansi

Or using yarn:

yarn add @softwarefactory-project/re-ansi

Add to your rescript.json:

"bs-dependencies": [
+  "@softwarefactory-project/re-ansi"
]

Usage

In reason:

let log = "green color: \x1b[01m\x1b[01;32mOK\x1b[00m";

@react.component
let make = () => {
  <Ansi log />
}

In javascript:

import Ansi from "@softwarefactory-project/re-ansi";

let make = () => (
  <Ansi log="content..." />;
);

Contribute

Contributions are most welcome, for example the project needs help to:

• support more ANSI code.
• enable custom colors, such as solarized, by changing the fourBitColors function to a property.

Get started by running:

git clone https://github.com/softwarefactory-project/re-ansi
cd re-ansi
npm install
npm run test

Then build and run tests with yarn test.

Make sure to read about React and Reason too.
