开源软件名称：esamattis/underscore.string开源软件地址：https://github.com/esamattis/underscore.string开源编程语言：JavaScript 100.0%开源软件介绍：The stable release documentation can be found here https://epeli.github.io/underscore.string/ Underscore.string
Javascript lacks complete string manipulation operations. This is an attempt to fill that gap. List of build-in methods can be found for example from Dive Into JavaScript. Originally started as an Underscore.js extension but is a full standalone library nowadays. Upgrading from 2.x to 3.x? Please read the changelog. UsageFor Node.js, Browserify and WebpackInstall from npm Require individual functions var slugify = require("underscore.string/slugify");
slugify("Hello world!");
// => hello-worldor load the full library to enable chaining var s = require("underscore.string");
s(" epeli ").trim().capitalize().value();
// => "Epeli"but especially when using with Browserify the individual function approach is recommended because using it you only add those functions to your bundle you use. In MeteorFrom your Meteor project folder meteor add underscorestring:underscore.stringand you'll be able to access the library with the s global from both the server and the client. s.slugify("Hello world!");
// => hello-world
s(" epeli ").trim().capitalize().value();
// => "Epeli"OthersThe Underscore.js/Lo-Dash integrationIt is still possible use as Underscore.js/Lo-Dash extension _.mixin(s.exports());But it's not recommended since Lo-Dash-FP/Ramda integrationIf you want to use underscore.string with ramdajs or Lo-Dash-FP you can use underscore.string.fp. var S = require('underscore.string.fp');
var filter = require('lodash-fp').filter;
var filter = require('ramda').filter;
filter(S.startsWith('.'), [
'.vimrc',
'foo.md',
'.zshrc'
]);
// => ['.vimrc', '.zshrc']Download
APIIndividual functionsnumberFormat(number, [ decimals=0, decimalSeparator='.', orderSeparator=',']) => stringFormats the numbers. numberFormat(1000, 2);
// => "1,000.00"
numberFormat(123456789.123, 5, ".", ",");
// => "123,456,789.12300"levenshtein(string1, string2) => numberCalculates [Levenshtein distance][ld] between two strings. [ld]: http://en.wikipedia.org/wiki/Levenshtein_distance levenshtein("kitten", "kittah");
// => 2capitalize(string, [lowercaseRest=false]) => stringConverts first letter of the string to uppercase. If capitalize("foo Bar");
// => "Foo Bar"
capitalize("FOO Bar", true);

// => ["whi", "tes", "pac", "e"]clean(string) => stringTrim and replace multiple spaces with a single space. clean(" foo bar ");
// => "foo bar"cleanDiacritics(string) => stringReplace diacritic characters with closest ASCII equivalents. Check the source for supported characters. Pull requests welcome for missing characters! cleanDiacritics("ääkkönen");
// => "aakkonen"chars(string) => arraychars("Hello");
// => ["H", "e", "l", "l", "o"]swapCase(string) => stringReturns a copy of the string in which all the case-based characters have had their case swapped. swapCase("hELLO");
// => "Hello"include(string, substring) => booleanTests if string contains a substring. include("foobar", "ob");
// => truecount(string, substring) => numberReturns number of occurrences of substring in string. count("Hello world", "l");
// => 3escapeHTML(string) => stringConverts HTML special characters to their entity equivalents. This function supports cent, yen, euro, pound, lt, gt, copy, reg, quote, amp, apos. escapeHTML("<div>Blah blah blah</div>");
// => "<div>Blah blah blah</div>"unescapeHTML(string) => stringConverts entity characters to HTML equivalents. This function supports cent, yen, euro, pound, lt, gt, copy, reg, quote, amp, apos, nbsp. unescapeHTML("<div>Blah blah blah</div>");
// => "<div>Blah blah blah</div>"insert(string, index, substring) => stringinsert("Hellworld", 4, "o ");
// => "Hello world"replaceAll(string, find, replace, [ignorecase=false]) => stringreplaceAll("foo", "o", "a");

// => "Hello. Worl.d "
wrap("Hello World", { width:5, seperator:'.', preserveSpaces: true })
// => "Hello .World"dedent(str, [pattern]) => stringDedent unnecessary indentation or dedent by a pattern. Credits go to @sindresorhus. This implementation is similar to https://github.com/sindresorhus/strip-indent dedent(" Hello\n World");
// => "Hello\n World"
dedent("\t\tHello\n\t\t\t\tWorld");
// => "Hello\n\t\tWorld"
dedent(" Hello\n World", " "); // Dedent by 2 spaces
// => " Hello\n World"reverse(string) => stringReturn reversed string: reverse("foobar");
// => "raboof"splice(string, index, howmany, substring) => stringLike an array splice. splice("https://[email protected]/edtsech/underscore.strings", 30, 7, "epeli");
// => "https://[email protected]/epeli/underscore.strings"startsWith(string, starts, [position]) => booleanThis method checks whether the string begins with startsWith("image.gif", "image");
// => true
startsWith(".vimrc", "vim", 1);

// => true
endsWith("image.old.gif", "old", 9);
// => truepred(string) => stringReturns the predecessor to str. pred("b");
