重新排序正则表达式匹配组 [英] Reorder Regex Match Groups

问题描述

我正在为 grails 编写 Sublime Text 2 构建配置，其中包括一个正则表达式(perl 样式)，用于将错误消息解析为文件、行、列和消息部分.错误来自以下格式的 grails CLI:

I am writing a Sublime Text 2 build configuration for grails, which includes a regular expression (perl style) to parse error messages in to file, line, column, and message parts. The errors come from the grails CLI in the following format:

{Project_Directory}/SourceFile.groovy: 19: errror_message @ line 19, column 5.

我当前的正则表达式匹配所有四个部分，但 Sublime 似乎要求匹配按顺序发生，即匹配组 1 = 文件名，2 = 行号，3 = 列号，4 = 错误消息.Grails 以相反的顺序报告第 3 项和第 4 项，因此我需要编写一个正则表达式，将列号放在匹配组 3 中，将错误消息放在组 4 中.我当前的正则表达式(匹配，但不反转组 3和 4) 如下:

My current regex matches all four parts, but Sublime seems to require that the matches occur in order, that is match group 1 = file name, 2 = line number, 3 = column number, 4 = errror message. Grails is reporting items 3 and 4 in reverse order, so I need to write a regex that will put the column number in match group 3 and the error message in group 4. My current regex (which matches, but doesn't reverse groups 3 and 4) is as follows:

^(.+?): (\d+): (.+?) \@ line \d+, column (\d+)\.$

有什么想法吗?这甚至可能吗?有人知道 sublime 是否会接受命名组而不是编号组?

Any ideas? Is this even possible? Does anybody know if sublime will accept named groups instead of numbered groups?

推荐答案

^(.+?): (\d+): (?=.+? \@ line \d+, column (\d+)\.$)(.+?) \@

更好(更少的失败回溯):

Better (less backtracking on failure):

^([^:]+): (\d+): (?=[^@]+ \@ line \d+, column (\d+)\.$)([^@]+) \@
