I don't know if ecaradec's plugin supports this yet, but one thing you can do with plugins that people haven't been using yet is you can let an alias call a plugin directly. This isn't really much different than calling it when someone types something in but if you read my suggestion you'll see why i mention it.
I think it would be really useful to have a generic plugin that was meant to be called from alieses.
Here's what the plugin would do, it would be invoked like this:
webgrab URL "regexgrab" "outputformat"
This would cause plugin to
1. grab the page at URL
2. Match text regexgrab
with pattern group matching
3. Display memo result of outputformat
doing replacement of matched groups
This webgrab function is generic function that anyone could write aliases for.
So for example i might write an alias like this:
Alias: wtemp (.*)
Invokes: webgrab.dll webgrab http://www.weather.com/weather/local/
$$1 "Feels like (.*)F" "Weather in your town is %1 degrees"
using this alias would cause the webgrab plugin to:
1. grab the page at http://www.weather.c.../weather/local/61820
2. Match text Feels like (.*)F
3. Display memo result of Weather in your town is %1 degrees (where %1 is the regex pattern match in step 2)
Hope its not too confusing to see the dual use of regular expressions and replacement..
Basically the alias has its own regex match which grabs the users zipcode that they type,
And then the second use is when telling the webgrab plugin how to match and display results.
The idea is that this one plugin could be used by lots of people to make and share different aliases that could grab all kinds of info from web pages.
