Capturing Room Exits in a String List
|
typical exit line:
You see exits leading north, northeast, east, southeast, south, southwest (open door), west, and northwest.
Question:
How do I get all those directions in a string list variable? like north|west|south or whatever (not interested in the doors part, just added it so you know it can be there)
I got the part with 'north, northeast, east, southeast, south, southwest (open door), west, and northwest.' in a variable.
I just need something to detect the directions in it and add them to a string list variable.. Any thoughts? |

#trig {^You see exits leading (*).} {#var exits %replace(%replace(%replace(%1," (open door)","")," and",""),", ","|")}
This might not work for rooms with fewer than two exits, since the trigger might not patch. |

| Code: |
#IF (%regex( @neo_exits, " north\b") != 0) {#additem neo_dir " north "}
#IF (%regex( @neo_exits, " south\b") != 0) {#additem neo_dir " south "}
#IF (%regex( @neo_exits, " east\b") != 0) {#additem neo_dir " east "}
#IF (%regex( @neo_exits, " west\b") != 0) {#additem neo_dir " west "}
#IF (%regex( @neo_exits, " northwest\b") != 0) {#additem neo_dir " northwest "}
#IF (%regex( @neo_exits, " northeast\b") != 0) {#additem neo_dir " northeast "}
#IF (%regex( @neo_exits, " southwest\b") != 0) {#additem neo_dir " southwest "}
#IF (%regex( @neo_exits, " southeast\b") != 0) {#additem neo_dir " southeast "}

That's how I got it to work.. It's very dirty but it does the job even for 1 exit per room... If anyone has a cleaner way to do it please share |

I don't think it's any cleaner than your's but here's another way
| Code: |
| #fo %subregex(%subregex(%subregex(%lower(@myvar),"(\b\w*(?:north|east|south|west)\w*)","%upper(%1)"),"(\w)","%char(%eval(%ascii(%1)+32))"),"([^a-z]+)","|") {#additem mylist %i} |
I really wish there was a way to do case sensitive regexes |

Yeah, it's kinda pants that zMUD doesn't support the i option. You can use it in CMUD with the in-line regex syntax that's been added, but not in zMUD :(
