irc-formatting

IRC Formatting

Turns IRC formatted text into easy to use blocks. This library is meant to parse and facilitate compiling to and from the irc caret notation. If you're looking for a means to style messages that your bot sends out, or merely strip the formatting, I'd suggest you check out irc-colors instead.

Installation

npm install irc-formatting --save

Usage

> var ircf = require('irc-formatting');
> s = "Hello, \x02World\x0304,07!\x03\x02";
> b = ircf.parse(s);
[ Block {
    text: 'Hello, ',
    bold: false,
    italic: false,
    underline: false,
    reverse: false,
    color: -1,
    highlight: -1 },
  Block {
    text: 'World',
    bold: true,
    italic: false,
    underline: false,
    reverse: false,
    color: -1,
    highlight: -1 },
  Block {
    text: '!',
    bold: true,
    italic: false,
    underline: false,
    reverse: false,
    color: 4,
    highlight: 7 } ]
> ircf.renderIrc(b);
'Hello, \u0002World\u000304,07!\u000f'
> ircf.renderHtml(b);
'Hello, <b>World</b><span class="ircf-fg-4 ircf-bg-7"><b>!</b></span>'

Methods

• Block[] .parse(string text): Parse text into blocks
• string .renderIrc(Block[] blocks): Turn blocks back into irc-formatted text.
• string .renderHtml(Block[] blocks): Convert blocks into html (see below)
• string .renderHtml(string text): Convert text into html (see below)
• string .strip(Block[] blocks): Same as compile, but leaving out all formatting carets
• string .strip(string text): Parse text and turn result into unformatted text
• Block[] .removeStyle(Block[] blocks): Remove all non-color formatting from blocks
• Block[] .removeColor(Block[] blocks): Remove all color from blocks
• Block[] .compress(Block[] blocks): Merges adjacent blocks that have equal color and style, which can happen after the two first functions or when this library is used to render.
• string .swigFilter(string input, bool inline): Convert irc-formatted text into html. If inline is set, it will concaterate each line instead of wrapping them in <p> tags.

Note: .removeStyle, .compress and .removeColor does not clone the block array. .strip does not alter the blocks, however.

Block Class

• Block(Block prev, string text): Constructs a block. If prev is not null, the block will inherit style and color from it.
• .equals(Block other): Returns true if block's style and color equals the other's. It does not check for text equality.
• .isPlain(): Return true if the block has no style or color.
• .hasSameColor(Block other, bool reversed): Returns true if the blocks has the same color. If reversed argument is true and the current block has .reverse set, it will only return true if the colors are reversed.
• .getColorString(): Returns XX or XX,YY formatted string where XX is .color and YY is .highlight. Both numbers are padded to 2 length.

Constants

• .U: Underline
• .B: Bold
• .I: Italic
• .C: Color
• .R: Reverse
• .O: Reset (CTRL + O on mIRC)

HTML Rendering

.U, .B and .I will use <u>, <b> and <i> tags respectively, while the others will use <span>-tags with the following classes.

• ircf-reverse: Reversing is applied (color and higliht are swapped)
• ircf-no-color: The above class is set, but neither of the below are.
• ircf-fg-X: Foreground color (X = block.color)
• ircf-bg-X: Background color (X = block.highlight)

The output of .renderHtml is a string of tags without a tag wrapping all of it. .swigFilter will use the class ircf-line on its <p> tags.

Using with swig

In the initialization phase of your swig instance, you can add custom filters to swig like this. Make note of the first parameter.

swig.setFilter('ircf', require('irc-formatting').swigFilter);

Then you can use it in your templates like this.
