variable manipulation
|
Let's say I have the following
| Code: |
| #TR (^(*)$) {#fo @list {#tempvar newline %replace(%line(),%i,"")}} |
Is there a way to do this without creating a variable? I want it to manipulate %line() then, when the forall ends, I'll put it in a variable. |

Local variables do this,
| Code: |
#TR (^(*)$) {#fo @list {$tempLine = %replace(%line(),%i,"")};#VAR newline $tempLine}
|
I'd suggest making your trigger pattern more specific if possible because a script like this checking every line will bog cmud down. |

It depends on what he intends to do with the final variable. If he needs to do something additional
whether or not the line contains anything from @list, then he may need something like this.
Aslanthekat, can you tell us what this is for? |

When I do a scan I see
| Quote: |
West (Room is dark):
(Flying) (Demonic) (Sneak) A spectral soldier turns and attacks!
North (Room is dark):
(Flying) (Demonic) (Sneak) A wraith warrior floats here.
South (Room is dark):
(Flying) (Demonic) (Sneak) A wraith warrior floats here.
(Flying) (Demonic) (Sneak) A wraith warrior floats here. |
I have all the flags in @list. So the script looks at the line, strips all the flags and then trims any left over spaces leaving me with "A wraith warrior floats here.".
Then I think I'm going to add "A wraith warrior floats here." to a list called WestScan or EastScan or whatever.
This is what I have so far.
| Code: |
$newline = %1
//Clean up scan lines
#fo @flags {$newline = %remove(%i,$newline)}
$newline = %trim($newline)
//Check if line is a direction
#if (%ismember($newline,%dbkeys(@dirscan))) {
dir = %db(@dirscan, $newline)}
//add newline to proper list
#if (%ismember($newline,@ignorescan)) {} {
#var %concat(@dir,scan) %additem($newline,%concat(@dir,scan))} |
This works up until the add newline to list part, but thats a different issue. I can get that.
However, when I set the dir var I tried to use $dir and it didn't work for me. I'm guessing it was a scope issue.
My original question was if I could send %1, or %line() through the forall without assigning any sort of variable. Doing it that way, each time through the loop it it reset itself back to the original %1, so I was ending up with only the last flag in my @flags being removed from the line. |

No, you can't modify %1 or %line in any way. I don't really see the advantage to doing that versus using a local variable anyway...
EDIT: You could also use a named capture and just reference that local variable instead of %1. You would be able to reassign to that. |
