Rascal:字符串拆分函数

Question

在rascal中对字符串使用split()时，是否可以保留文字分隔符？

例如,

split("/*", line)

Answer 1

我能够创建我自己的拆分函数。它不是完美的，但它似乎解决了我之前面临的问题。

public list[str] splitString(list[str] fileLines)
{
    list[str] splitList = [];

    for(line <- fileLines)
    {
        if( /^<x:.*>\/\*<y:.*>$/ := line)
        {
            splitList = splitList + x;
            splitList = splitList + "/*";
            splitList = splitList + y;
        }
        else if(/^<x:.*>\*\/<y:.*>$/ := line)
        {   
            splitList = splitList + x;
            splitList = splitList + "*/";
            splitList = splitList + y;
        }
        else
        {
            splitList = splitList + line;
        }
    }

    return splitList;
}
