python - LARK:解析:实现导入文件？

您将如何实现可以导入文件并仍然使用LARK对其进行语法分析的语法？

f.e .：

@import file.txt
.....

最佳答案

我发现了一个与您正在寻找的GitHub相关的GitHub？
https://github.com/lark-parser/lark

from lark import Lark
with open('file_to_read.txt', 'r') as file:
    data = file.read().replace('\n', '') #assumes you want to remove \n
l = Lark('''start: WORD "," WORD "!"
            %import common.WORD   // imports from terminal library
            %ignore " "           // Disregard spaces in text
         ''')

print( l.parse("Hello, World!") )
print( l.parse(data) )

如果要打开文件并将其用作百灵鸟

from lark import Lark
with open('file_to_read.txt', 'r') as file:
    data = file.read().replace('\n', '') #assumes you want to remove \n
l = Lark(data)

print( l.parse("Hello, World!") )
print( l.parse("your string to parse") )
