DDX<0&大买>=20&伍特买>=32.4&主动1>=0&0<=涨<9 EmEditor的正则表达...

Formulating EmEditor regex

The user wants to use EmEditor to replace the variable parts of expressions to wrap them in lag(var,离板-1). They gave an example of transforming 0<=涨<9 to 0<=lag(涨,离板-1)<9. It seems like they want to identify conditions involving variables (e.g., DDX<0), and for each variable, wrap it with the lag() function while keeping comparison operators and numbers unchanged. I need to build a regex pattern that matches the variable sections and applies this transformation.

Proposing EmEditor regex

For this EmEditor regex challenge, we need to ensure we capture variable names properly while excluding numbers and other non-variable parts. The key is identifying variables (including Chinese characters and letters) with comparison signs. A pattern like [A-Za-z\u4e00-\u9fa5_]+ should work for variables, ensuring numbers or other text aren’t matched. We'll also need negative lookbehind to avoid matching variables already wrapped in lag(...). Matching variables before or after comparison operators, we can use $0 or \1 for backreferences, depending on EmEditor’s specifics.
