这是我的解决方案。它解析大多数理智的输入,就像它直接传递到命令行一样。
import re
def simpleParse(input_):
def reduce_(quotes):
return '' if quotes.group(0) == '"' else '"'
rex = r'("[^"]*"(?:\s|$)|[^\s]+)'
return [re.sub(r'"{1,2}',reduce_,z.strip()) for z in re.findall(rex,input_)]
用例:将一堆单次脚本收集到实用程序启动器中,而无需重做命令输入。
编辑:得到了关于命令行处理蹩脚引用的愚蠢方式的强迫症,并写了以下内容:
import re
tokens = list()
reading = False
qc = 0
lq = 0
begin = 0
for z in range(len(trial)):
char = trial[z]
if re.match(r'[^\s]', char):
if not reading:
reading = True
begin = z
if re.match(r'"', char):
begin = z
qc = 1
else:
begin = z - 1
qc = 0
lc = begin
else:
if re.match(r'"', char):
qc = qc + 1
lq = z
elif reading and qc % 2 == 0:
reading = False
if lq == z - 1:
tokens.append(trial[begin + 1: z - 1])
else:
tokens.append(trial[begin + 1: z])
if reading:
tokens.append(trial[begin + 1: len(trial) ])
tokens = [re.sub(r'"{1,2}',lambda y:'' if y.group(0) == '"' else '"', z) for z in tokens]
