Extracting numbers from string Topic is solved

[jmcall10]

Hi All,

I have a string which I require to extract the numerical valuses from.
Here is an example of the string:
"149 APPLES 1205 ORANGES AND 151 APPLES 1263 ORANGES"

I would like to extract it as follows:
variable 1 = 149
variable 2 = 1205
variable 3 = 151
variable 4 = 1263

Some things to consider:
The format is always the same."X APPLES X ORANGES AND X APPLES X ORANGES"
Each numbers length can vary from 1 digit to 4 digits long.

Hope this makes sense to someone.

Regards,

Code: Select all

#SingleInstance, Force

TestString := "149 APPLES 1205 ORANGES AND 151 APPLES 1263 ORANGES"

Pos := 1

While Pos := RegExMatch(TestString, "(\d+)", Match, Pos + StrLen(Match)) {
	Variable%A_Index% := Match
}

Result =
(LTrim
	Variable 1 = %Variable1%
	Variable 2 = %Variable2%
	Variable 3 = %Variable3%
	Variable 4 = %Variable4%
)

MsgBox, % Result

I have managed to achieve what I was after using a different approach (most likely not a very good approach)

MyString := "149 APPLES 1205 ORANGES AND 151 APPLES 1263 ORANGES"
word_array := StrSplit(MyString , A_Space, ".") ; Omits periods.
MsgBox % "The 1st number is" word_array[1]
MsgBox % "The 2nd number is" word_array[3]
MsgBox % "The 3rd number is" word_array[6]
MsgBox % "The 4th number is" word_array[8]

This only works if the format of the string never changes.

Code: Select all

string := "149 APPLES 1205 ORANGES AND 151 APPLES 1263 ORANGES"
RegExMatch(string, "\b\d+\b(?CmakeVars)")

makeVars(match) {
	global

	static i := 1

	variable%i% := match
	++i

	return 1
}

edit: fix local static i := 1 to static i := 1. see post below

This doesn't do what you think,

Code: Select all

local static i := 1

Check listvars.

Cheers.

yes, it should be just static i := 1
i dont understand how the incorrect version is parsed, though:

Code: Select all

local static i := 1

local static declares a blank local variable called 'static'
so what is i then? its not global, since it doesnt leak. its not pure local, since it gets incremented between function calls. so its static then, but if the keyword 'static' in this context is the name of a var, what tells i to become a static var?

[Helgef]

i is static. An error would be more appropriate.

Cheers.

Edit: it is an error in v2
