当您在Rascal中有一个字符串时,这样:
"\n\tThis is a specification of a toy Transaction.\n\tVia a transaction money
can be transfered between two accounts\n"
或者
This is a specification of a toy Transaction.
Via a transaction money can be transfered between two accounts
如何删除字符串中间的空格?
我现在的解决方案是调用一个替换'\ n','\ t'和'\ r'的函数,但这似乎不是一个可持续的解决方案。此外,函数trim仅删除开头和结尾的空格。
