正向负向后向向前看 [英] lookarounds positive negative lookbehind lookahead

问题描述

在整个Google上搜索vsvim向前或向后搜索后，并在 wiki 上，我可以似乎无法弄清楚它是如何支持前瞻性或后向性(正数或负数)，以及如何使用它们.

after searching all over google for vsvim lookahead or lookbehind and on the wiki I can't seem to figure out how, or if it even supports lookahead or lookbehind (positives or negatives) and how to use them if so.

我尝试了几种不同的语法，如\ze \@=我在vim 答案上看到的(?<=let \w\+)( \(?<=let \w\+\)(，但它们似乎都无法在vs vim中使用匹配(不替换)

I've tried a few different syntaxes like \ze \@= (?<=let \w\+)( \(?<=let \w\+\)( that I've seen on vim answers but none of them seem to be working in vs vim for matching (nor substitution)

您如何在VsVim中环顾四周?

how do you do lookarounds in VsVim?

/\(Start\)\@<!Date

这将与"EndDate"和"YesterdaysDate"中的"Date"匹配，但与"StartDate"不匹配

This will match the 'Date' in 'EndDate' and 'YesterdaysDate' but will not match 'StartDate'

/Start\(Date\)\@!

将与开始"中的开始"相匹配，而不与"StartDate"中的开始"相符

will match the 'Start' in 'Starting but not in 'StartDate'

/Start\(Date\)\@=

将与"StartDate"中的"Start"相匹配，而不与"Starting"中的"

will match the 'Start' in 'StartDate' but not in 'Starting

/\(Start\)\@<=Date

将与"StartDate"中的"Date"匹配，但与"EndDate"和"YesterdaysDate"中的不匹配

will match the 'Date' in 'StartDate' but not in 'EndDate' and 'YesterdaysDate'
