Re: counting characters in lua

Hi,

thats pretty simple. You need to get the # signs out of the string, either by creating a trigger for it, or parsing it out of the already available string inside a script. Lets take the following for example:

s = 'Summon rift entity: ##'

Now you need to create a small regular _expression_ from scratch that will handle all lines which start with something textual (any amount of characters), followed by a colon, followed by a whitespace and the amount of # you seek (at least once). That might look like the following:

regexp = '%w*: (#+)'

Now you can use string.match() to get the hashtags out of your text:

hashtags = string.match(s, regexp)

Now, the hashtag itself solves our problem here . The hashtag sign in lua returns the amount of items within a collection, like the amount of number-indices in a table, or the amount of characters in a string. Thus, the following will work:

amount = #hashtags

amount will now contain the amount of hashtags found in your text. The same procedure can be used directly within a trigger, you'll just have to configure it to parse as a regular _expression_ and use the wildcard %1 instead of the hard-formatted text above:

s = '%1'

Hope that helps.

Best Regards.
