From 190295b9b8e20d1c503336a492f237b91082c5a4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Mojach=C3=A9?= Date: Sat, 13 Apr 2024 08:03:58 +0000 Subject: [PATCH 01/13] Updated colorRegEx to better reflect spec Made rgb/rgba more spec compliant: https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/rgb#values https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/rgba#values https://developer.mozilla.org/en-US/docs/Web/CSS/alpha-value Both rgb and rgba contain the optional parameter of alpha despite naming convention. R, G, B are required; A is optional for both. Test cases: ["rgb(153,255,153,0.5)","rgb(253, 255, 153)","rgb(255 255 255 / 50.75%)","rgba(255, 255, 255 / 50%)","rgb(255, 255, 255, none)","rgba(none, 255, 255 / none)"] Changes (Line references use my changed code): - Reduce processing, one regex for both cases. [Line 32] - Augment to allow flexibility with parts.length being either 3 or 4. [Line 84, 306-323] - Simplify logic into a longer ternary operator rather than 3 cases. [Line 83-86] - Augment split to take several white space, comma, or / delimiters as per spec. [Line 82, 306] - Alpha can now be a %. - Added support for "none" keyword for a rgba value. --- lib/parsers.js | 105 ++++++++++++------------------------------------- 1 file changed, 25 insertions(+), 80 deletions(-) diff --git a/lib/parsers.js b/lib/parsers.js index 887bd51..8dd3c92 100644 --- a/lib/parsers.js +++ b/lib/parsers.js @@ -29,8 +29,7 @@ var percentRegEx = /^[-+]?[0-9]*\.?[0-9]+%$/; var urlRegEx = /^url\(\s*([^)]*)\s*\)$/; var stringRegEx = /^("[^"]*"|'[^']*')$/; var colorRegEx1 = /^#([0-9a-fA-F]{3,4}){1,2}$/; -var colorRegEx2 = /^rgb\(([^)]*)\)$/; -var colorRegEx3 = /^rgba\(([^)]*)\)$/; +var colorRegEx2 = /^rgba?\(([^)]*)\)$/; var calcRegEx = /^calc\(([^)]*)\)$/; var colorRegEx4 = /^hsla?\(\s*(-?\d+|-?\d*.\d+)\s*,\s*(-?\d+|-?\d*.\d+)%\s*,\s*(-?\d+|-?\d*.\d+)%\s*(,\s*(-?\d+|-?\d*.\d+)\s*)?\)/; @@ -80,33 +79,12 @@ exports.valueType = function valueType(val) { var res = colorRegEx2.exec(val); var parts; if (res !== null) { - parts = res[1].split(/\s*,\s*/); - if (parts.length !== 3) { - return undefined; - } - if ( - parts.every(percentRegEx.test.bind(percentRegEx)) || - parts.every(integerRegEx.test.bind(integerRegEx)) - ) { - return exports.TYPES.COLOR; - } - return undefined; - } - res = colorRegEx3.exec(val); - if (res !== null) { - parts = res[1].split(/\s*,\s*/); - if (parts.length !== 4) { - return undefined; - } - if ( - parts.slice(0, 3).every(percentRegEx.test.bind(percentRegEx)) || - parts.slice(0, 3).every(integerRegEx.test.bind(integerRegEx)) - ) { - if (numberRegEx.test(parts[3])) { - return exports.TYPES.COLOR; - } - } - return undefined; + parts = res[1].split(/[\s,\/]+/); + var rgb = parts.slice(0, 3).map(col => col.toLowerCase() == "none" ? 0 : col); + return ( + (parts.length == 3 || parts.length == 4) && + (rgb.every(percentRegEx.test.bind(percentRegEx)) || rgb.every(integerRegEx.test.bind(integerRegEx))) + ) ? exports.TYPES.COLOR : undefined; } if (colorRegEx4.test(val)) { @@ -325,57 +303,24 @@ exports.parseColor = function parseColor(val) { res = colorRegEx2.exec(val); if (res) { - parts = res[1].split(/\s*,\s*/); - if (parts.length !== 3) { - return undefined; - } - if (parts.every(percentRegEx.test.bind(percentRegEx))) { - red = Math.floor((parseFloat(parts[0].slice(0, -1)) * 255) / 100); - green = Math.floor((parseFloat(parts[1].slice(0, -1)) * 255) / 100); - blue = Math.floor((parseFloat(parts[2].slice(0, -1)) * 255) / 100); - } else if (parts.every(integerRegEx.test.bind(integerRegEx))) { - red = parseInt(parts[0], 10); - green = parseInt(parts[1], 10); - blue = parseInt(parts[2], 10); - } else { - return undefined; - } - red = Math.min(255, Math.max(0, red)); - green = Math.min(255, Math.max(0, green)); - blue = Math.min(255, Math.max(0, blue)); - return 'rgb(' + red + ', ' + green + ', ' + blue + ')'; - } - - res = colorRegEx3.exec(val); - if (res) { - parts = res[1].split(/\s*,\s*/); - if (parts.length !== 4) { - return undefined; - } - if (parts.slice(0, 3).every(percentRegEx.test.bind(percentRegEx))) { - red = Math.floor((parseFloat(parts[0].slice(0, -1)) * 255) / 100); - green = Math.floor((parseFloat(parts[1].slice(0, -1)) * 255) / 100); - blue = Math.floor((parseFloat(parts[2].slice(0, -1)) * 255) / 100); - alpha = parseFloat(parts[3]); - } else if (parts.slice(0, 3).every(integerRegEx.test.bind(integerRegEx))) { - red = parseInt(parts[0], 10); - green = parseInt(parts[1], 10); - blue = parseInt(parts[2], 10); - alpha = parseFloat(parts[3]); - } else { - return undefined; - } - if (isNaN(alpha)) { - alpha = 1; - } - red = Math.min(255, Math.max(0, red)); - green = Math.min(255, Math.max(0, green)); - blue = Math.min(255, Math.max(0, blue)); - alpha = Math.min(1, Math.max(0, alpha)); - if (alpha === 1) { - return 'rgb(' + red + ', ' + green + ', ' + blue + ')'; - } - return 'rgba(' + red + ', ' + green + ', ' + blue + ', ' + alpha + ')'; + parts = res[1].split(/[\s,\/]+/); + var rgb = parts.slice(0, 3).map(col => col.toLowerCase() == "none" ? 0 : col); + if (rgb.every(percentRegEx.test.bind(percentRegEx))) { + [red, green, blue] = rgb.map(code => Math.floor((parseFloat(code.slice(0, -1)) * 255) / 100)); + } else if (rgb.every(integerRegEx.test.bind(integerRegEx))) { + [red, green, blue] = rgb.map(code => parseInt(code, 10)); + } else { + return undefined; + } + [red, green, blue] = [red, green, blue].map(code => Math.min(255, Math.max(0, code))); + var base = [red, green, blue].join(', '); + if(parts.length == 4) { + alpha = parts[3] == "none" ? 0 : (percentRegEx.test(parts[3]) ? parseFloat(parts[3].slice(0, -1)) / 100 : parseFloat(parts[3])); + alpha = isNaN(alpha) ? 1 : Math.min(1, Math.max(0, alpha)); + } else { + alpha = 1; + } + return (alpha >= 0 && alpha < 1) ?
