JS文本差分 Jsdiff

Jsdiff是一款实现javascript文本差分的软件。

安装:

npm install diff

或者

bower install jsdiff

API

  • JsDiff.diffChars(oldStr, newStr[, options]) – diffs two blocks of text, comparing character by character.

    Returns a list of change objects (See below).

  • JsDiff.diffWords(oldStr, newStr[, options]) – diffs two blocks of text, comparing word by word, ignoring whitespace.

    Returns a list of change objects (See below).

  • JsDiff.diffWordsWithSpace(oldStr, newStr[, options]) – diffs two blocks of text, comparing word by word, treating whitespace as significant.

    Returns a list of change objects (See below).

  • JsDiff.diffLines(oldStr, newStr[, options]) – diffs two blocks of text, comparing line by line.

选择:

  • ignoreWhitespace: true to ignore leading and trailing whitespace. This is the same as diffTrimmedLines

  • newlineIsToken: true to treat newline
    characters as separate tokens.  This allows for changes to the newline
    structure to occur independently of the line content and to be treated
    as such. In general this is the more human

  • dly form of diffLines and diffLines is better suited for patches and other computer friendly output.

兼容性:

 Jsdiff支持所有ES3环境和IE8以下一些已知问题。这些浏览器存在一些差异算法,如文字diff和其他可能由于缺乏拆分操作捕获组支持的失败操作。
