Question

我想将这些关键词之一之后的任何案文归为几句。

投入:/send 1 at 11:00pm for 3min

预期结果:postNumber = 1, sentAt = 11:00pm,dur = 3min

投入:/send 1 for 3min

预期结果:postNumber = 1,dur = 3min

投入:/send 1 at 11:00p

预期结果:postNumber = 1, sentAt = 11:00pm

投入:/send 1 to 11:00p

预期结果:postNumber = 1, 直至 = 11:00pm

投入:/send 1 for 3min at 11:00 pm

预期结果:postNumber = 1, sentAt = 11:00 pm,dur = 3min

投入:/send 1 at 11am for 1 h

预期结果:postNumber = 1, sent = 11am, 有效期 = 1 h

我先做了以下小节,但可以预示如何使之符合关键词的投入顺序。

?

I tried to add positive lockahead but it matched all the digits in the first group (?<postNumber>d+)(?=(?: at (?<timeToSend>.*)))?(?=(?: for (?<duration>.*)))?(?=(?: until (?<until>.*)))?

你们可以把每个捕捉团体归入积极的头目,以便按以下顺序加以匹配:

/sends+(?<postNumber>d+)(?=(?:.*ats+(?<sendAt>d+(?::d+)?s*S+))?)(?=(?:.*fors+(?<duration>d+s*S+))?)(?=(?:.*untils+(?<until>d+(?::d+)?s*S+))?)
