Subject: Syntax: Using \v (very magic) in patterns in syntax files
 

I have noticed that patterns in published syntax files never use the `\v` (very magic) modifier. Is there any deeper reason than people's preferences for this? Being used to Perl patterns I practically always use it and find it hard to keep track of when to use backslashes when not using it. The result is that more or less subtle errors creep in when I'm writing a syntax file, so I'd prefer to use it unless it's a Really Bad Idea.

 

Hi

I deeply sympathise with you. It seems complete madness that the slashing is different for various quantifiers. (* recognised as a meta character, but not +  or ?). My reading of the help suggests that very magic doesn't cure this.

 

It does in that all ASCII punctuation characters can be escaped to be "normal" and those that are metacharacters are meta when not escaped. Word characters, quite sensibly do still need a backslash to be meta. That's consistent enough for me.

regards - Chris
