Regular expression for capturing all skin-tone variations of an emoji

阅读更多关于 Regular expression for capturing all skin-tone variations of an emoji

问题 I'm trying to use a regex to capture tweets containing the substring 👏 at least twice, so I'm using an unsophisticated ^.+ 👏 .+ 👏 .+$ . However this doesn't match strings which instead contain, for example, 👏🏼 . Is there a smart way I can capture an emoji with any or none skin-tone variation, without just putting each one in a row (like [👏👏🏻👏🏼👏🏽👏🏾👏🏿] )? 回答1: Thanks to comments above, I've found that emojis I've encountered on twitter are unicode, and skin-tone variations are combining

Optimization techniques for backtracking regex implementations

阅读更多关于 Optimization techniques for backtracking regex implementations

问题 I'm trying to implement a regular expression matcher based on the backtracking approach sketched in Exploring Ruby’s Regular Expression Algorithm. The compiled regex is translated into an array of virtual machine commands; for the backtracking the current command and input string indices as well as capturing group information is maintained on a stack. In Regular Expression Matching: the Virtual Machine Approach Cox gives more detailed information about how to compile certain regex components

Regex to replace values that include part of match in replacement in sublime?

问题 I've come up with this regex that finds all words that start with $ and contain _ underscores: \$(\w+)_(\w+) I'm basically searching for variables, like $var_foo etc. How do I replace stuff using the regex groups? For example, how can I remove the underscore and make the next letter uppercase, like $varFoo ? 回答1: The replacement expression is: \$\1\u\2 \1 , \2 are the captures (or $1 , $2 ) \u up-cases (see the Replacement String Syntax section). See the Regular Expressions chapter (in the
