    📋 Example

    const Anser = require("anser");
    
    const txt = "\u001b[38;5;196mHello\u001b[39m \u001b[48;5;226mWorld\u001b[49m";
    
    console.log(Anser.ansiToHtml(txt));
    // <span style="color:rgb(255, 0, 0)">Hello</span> <span style="background-color:rgb(255, 255, 0)">World</span>
    
    console.log(Anser.ansiToHtml(txt, { use_classes: true }));
    // <span class="ansi-palette-196-fg">Hello</span> <span class="ansi-palette-226-bg">World</span>
    
    console.log(Anser.ansiToJson(txt));
    // [ { content: '',
    //     fg: null,
    //     bg: null,
    //     fg_truecolor: null,
    //     bg_truecolor: null,
    //     clearLine: undefined,
    //     decoration: null,
    //     was_processed: false,
    //     isEmpty: [Function: isEmpty] },
    //   { content: 'Hello',
    //     fg: '255, 0, 0',
    //     bg: null,
    //     fg_truecolor: null,
    //     bg_truecolor: null,
    //     clearLine: false,
    //     decoration: null,
    //     was_processed: true,
    //     isEmpty: [Function: isEmpty] },
    //   { content: ' ',
    //     fg: null,
    //     bg: null,
    //     fg_truecolor: null,
    //     bg_truecolor: null,
    //     clearLine: false,
    //     decoration: null,
    //     was_processed: false,
    //     isEmpty: [Function: isEmpty] },
    //   { content: 'World',
    //     fg: null,
    //     bg: '255, 255, 0',
    //     fg_truecolor: null,
    //     bg_truecolor: null,
    //     clearLine: false,
    //     decoration: null,
    //     was_processed: true,
    //     isEmpty: [Function: isEmpty] },
    //   { content: '',
    //     fg: null,
    //     bg: null,
    //     fg_truecolor: null,
    //     bg_truecolor: null,
    //     clearLine: false,
    //     decoration: null,
    //     was_processed: false,
    //     isEmpty: [Function: isEmpty] } ]

    When using TypeScript without --esModuleInterop enabled you can do the following:

    import Anser = require('anser');
    const txt = "\u001b[38;5;196mHello\u001b[39m \u001b[48;5;226mWorld\u001b[49m";
    console.log(Anser.ansiToHtml(txt));
    // <span style="color:rgb(255, 0, 0)">Hello</span> <span style="background-color:rgb(255, 255, 0)">World</span>

    Or with --esModuleInterop enabled you can do the following:

    import Anser from 'anser';
    const txt = "\u001b[38;5;196mHello\u001b[39m \u001b[48;5;226mWorld\u001b[49m";
    console.log(Anser.ansiToHtml(txt));
    // <span style="color:rgb(255, 0, 0)">Hello</span> <span style="background-color:rgb(255, 255, 0)">World</span>

    📝 Documentation

    Anser.escapeForHtml(txt)

    Escape the input HTML.

    This does the minimum escaping of text to make it compliant with HTML. In particular, the '&','<', and '>' characters are escaped. This should be run prior to ansiToHtml.

    Params

    • String txt: The input text (containing the ANSI snippets).

    Return

    • String The escaped html.

    Anser.linkify(txt)

    Adds the links in the HTML.

    This replaces any links in the text with anchor tags that display the link. The links should have at least one whitespace character surrounding it. Also, you should apply this after you have run ansiToHtml on the text.

    Params

    • String txt: The input text.

    Return

    • String The HTML containing the tags (unescaped).

    Anser.ansiToHtml(txt, options)

    This replaces ANSI terminal escape codes with SPAN tags that wrap the content.

    This function only interprets ANSI SGR (Select Graphic Rendition) codes that can be represented in HTML. For example, cursor movement codes are ignored and hidden from output. The default style uses colors that are very close to the prescribed standard. The standard assumes that the text will have a black background. These colors are set as inline styles on the SPAN tags.

    Another option is to set use_classes: true in the options argument. This will instead set classes on the spans so the colors can be set via CSS. The class names used are of the format ansi-*-fg/bg and ansi-bright-*-fg/bg where * is the color name, i.e black/red/green/yellow/blue/magenta/cyan/white.

    Params

    • String txt: The input text.
    • Object options: The options passed to the ansiToHTML method.

    Return

    • String The HTML output.

    Anser.ansiToJson(txt, options)

    Converts ANSI input into JSON output.

    Params

    • String txt: The input text.
    • Object options: The options passed to the ansiToHTML method.

    Return

    • String The HTML output.

    Anser.ansiToText(txt)

    Converts ANSI input into text output.

    Params

    • String txt: The input text.

    Return

    • String The text output.

    Anser()

    The Anser class.

    Return

    • Anser

    setupPalette()

    Sets up the palette.

    escapeForHtml(txt)

    Escapes the input text.

    Params

    • String txt: The input text.

    Return

    • String The escpaed HTML output.

    Have an idea? Found a bug? See how to contribute.

    💖 Support my projects

    I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).

    However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:

    • Starring and sharing the projects you like 🚀

    • Buy me a book—I love books! I will remember you after years if you buy me one. 😁 📖

    • PayPal—You can make one-time donations via PayPal. I'll probably buy a coffee tea. 🍵

    • Support me on Patreon—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).

    • Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6

    Thanks! ❤️
