Idea[2.14] %scroll
|
I was thinking that with the %line function we can retrieve lines, but when it comes to making a system that automatically configures itself to a mud we need a way to search the scroll back buffer. There already is a way in the #SCROLL command, but the usage of it is messy for this and there is no way to know how many lines were returned. I am proposing a function version of this be made.
Syntax: %scroll(pattern,var1,var2,...varN)
Returns a list of lines that matched the specified pattern. 0 is the most recent line, 1 is the next oldest, etc. The optional VarN arguments contain the names of variables to store any captured subpatterns (subpatterns surrounded by parenthesis). The captured subpatterns are be in the form of a list. If no lines match null is returned and any variables in the varN arguments are unchanged.
Example:
| Code: |
#SHOW This is a line.
#SHOW This is another line!
#SHOW Yet another line of text.
#SHOW That should be enough lines.
#SHOW %scroll("^T") %scroll("(%w).$",LastWord) %scroll("another") @LastWord
Displays:
This is a line.
This is another line!
Yet another line of text.
That should be enough lines.
0|2|3 0|1|3 1|2 lines|text|line |
The varN part might be over the top. |

I'll add that to the wish list for the future.
