 |
|
AutoHotkey Expression Examples: "" %% () and all that.
because I can never get them right, so I made this.
Originally this was just going to be about IF statements (see sections H: , I: ), then it just started growing...
CONTENTS:
A: RETRIEVING COMMAND LINE PARAMETERS
B: COMMON THINGS AT THE BEGINNING OF AUTOHOTKEY SCRIPTS
C: WHEN TO USE %% AROUND VARIABLES x,%x%,(%x%)
D: ERASE A VARIABLE
E: SET A VARIABLE (:=) [store numbers, quoted strings]
F: SET A VARIABLE (=) [assign unquoted literal strings]
G: COPY A VARIABLE
H: IF STATEMENTS with ()
I: IF STATEMENTS without () [Translate the 1st, take the 2nd literally]
J: CHECK FOR A BLANK VARIABLE
K: STRING MANIPULATION
L: NUMBERS
M: FILE NAMES
N: REGULAR EXPRESSIONS
O: MISC AUTOHOTKEY NOTES, DEBUGGING TIPS
P: MISC AUTOHOTKEY SCRIPTS
Q: NAVIGATING WEB SITES
R: NEWBIE RECOMMENDED LEARNING SEQUENCE
S: Press ESC to cancel this scipt
T: THE AUTOHOTKEY RUN COMMAND
U: PASSING PARAMETERS TO AUTOHOTKEY SCRIPTS
V: PASSING PARAMETERS TO ANY PROGRAM
NOTE: ALL VARIABLES ARE STORED AS CHARACTER STRINGS !!!
Strings containing numbers are converted to numbers when needed, and the result is converted back to a string.
NOTE: Closing */ must be first thing on line. Otherwise you'll be asking yourself, "Why does my script stop running at this point, as if the whole rest of the script was commented out?"
Version 1.21 (08/24/2009)

My title: "" %% (), And All That, is taken from the wonderful book, Div, Grad, Curl, And All That: An Informal Text on Vector Calculus by H. M. Schey (1973)

Helpful!
Thanks for this.
You should consider doing some kind of clickable index version.
Perhaps if I have some time I will try  .

Version 1.04 03/08/2008
Added part A: WHEN TO USE %% AROUND VARIABLES
| Code: | /*
WHEN TO USE %% AROUND VARIABLES
LESSON #1 on %%:
The only place to use %x% is where a literal string NOT enclosed in
double-quotes is expected. Otherwise, don't use %% around a variable name.
*/
;Notice in the following examples that unquoted literal strings are expected.
; = assigns unquoted literal strings
n = Ishmael
x = Call me %n%
MsgBox Call me %n%
;Example
x = 500
y = 500
z = 10
MouseMove, 500, 500, 10 ;works
MouseMove, 500 - 1, 500 + 1, 10 ;works
MouseMove, x, y, z ;works
MouseMove, x - 1, y + 1, z + 2 ;works
;However, this doesn't work, because MouseMove
;doesn't expect an unquoted literal string
MouseMove, %x% - 1, %y% + 1, 10 ;doesn't work
;CONFUSION IS CAUSED BECAUSE THE FOLLOWING HAPPENS TO ALSO WORK
MouseMove, %x%, %y%, %c% ;works
;The above works because "for backward compatibility, command parameters
; that are documented as "can be an expression" treat an isolated name
; in percent signs (e.g. %Var%, but not Array%i%) as though the percent
; signs are absent."
; --AutoHotkey Documentation: Variables and Expressions
/*
LESSON #2 on %%:
Use (%x%) when x contains the name of a 2nd variable which in
turn contains the contents you want.
*/
a = 500 ;a = "500"
b = 200 ;b = "200"
x := "a"
y := "b"
MouseMove, (%x%), (%y%) ;x = a, a = 500. y = b, b = 200
MouseGetPos, xpos, ypos
MsgBox xpos=%xpos% ypos=%ypos% ;xpos=500 ypos=200

A handy interface for this might be the Scriptlet library tool
Scriptlet Library v4
http://www.autohotkey.com/forum/viewtopic.php?t=2510
should also move this thread to "scripts & functions" forum
