EditPlus实现json格式化

Posted by 冷眼樵夫 on 07-09,2021

最近接触json格式化操作比较多,每次都需要找在线工具,有点繁琐,遂尝试在常用编辑器增加插件。我常用editplus,步骤如下:

1.准备js脚本

在editPlus安装目录下,创建文件JsonFormat.js(名字随意,大家喜欢就好),编辑文件(内容如下,大家可以直接复制):

//程序开始
var __input_json = "";
while (!WScript.StdIn.AtEndOfStream) {
    __input_json += WScript.StdIn.ReadAll();
}
var format_str = '';
if (__input_json) {
    //if(WScript.Arguments.length)
    var _json=__input_json.replace(/^\s+/, '');
    format_str = js_beautify(_json);  
}
format_str.length?WScript.Echo(format_str):WScript.Echo('Are you sure your input is javascript source file?');

// 处理json
function js_beautify(js_source_text) {

    var input, output, token_text, last_type, last_text, last_last_text, last_word, flags, flag_store, indent_string;
    var whitespace, wordchar, punct, parser_pos, line_starters, digits;
    var prefix, token_type, do_block_just_closed;
    var wanted_newline, just_added_newline, n_newlines;


    // Some interpreters have unexpected results with foo = baz || bar;
    //options = options ? options : {};
    // 大括号另起一行 false:不换行; true 换行
    //var opt_braces_on_own_line = options.braces_on_own_line ? options.braces_on_own_line : true;
    var opt_braces_on_own_line =false;
    //缩进
    //var opt_indent_size = options.indent_size ? options.indent_size : 4;
    var opt_indent_size=4;
    //保留空行
    //var opt_indent_char = options.indent_char ? options.indent_char : ' ';
    var opt_indent_char =' ';
    //
    //var opt_preserve_newlines = typeof options.preserve_newlines === 'undefined' ? true : options.preserve_newlines;
     var opt_preserve_newlines =true;
    //var opt_indent_level = options.indent_level ? options.indent_level : 0; // starting indentation
    var opt_indent_level = 0;
    //var opt_space_after_anon_function = options.space_after_anon_function === 'undefined' ? false : options.space_after_anon_function;
    var opt_space_after_anon_function=true;

     var opt_keep_array_indentation =false;

    just_added_newline = false;

    // cache the source's length.
    var input_length = js_source_text.length;

    function trim_output() {
        while (output.length && (output[output.length - 1] === ' ' || output[output.length - 1] === indent_string)) {

    }

    }


    function print_newline(ignore_repeated) {

        flags.eat_next_space = false;
