Hi!
I'm using Maps (and I love 'em!), so I have to use the latest AutoIt Beta. I've switched to Beta mode, and the graphical debugger doesn't even show up in the Explorer context menu (not surprising). So I'd like to use _Dbug (rather than a large number of MsgBox statements), but it fails when it encounters a Map function (such as MapExists). I've made a request for a version that will work with the Beta, but going on past history, I don't expect an answer anytime soon.
I'm not necessarily asking for someone else to modify _Dbug, because I can probably do it myself, as long as I know how to adapt it to use the Beta. Can someone please enlighten me as to how to adapt a UDF or other function to use AutoIt Beta?
Thanks!

Im not sure if this is intended but normally Autoit variables are always passed as copies (except objects i think).
But below i observed an unconsistency when copying maps with nested maps inside.
Issue:
If you create a nested map1 and copy it to a new map2, changing a nested value in map2 will also change the nested value in map1
Dim $player[] Dim $sub[] $player.test1 = 1 $player.test2 = $sub $player.test2.child1 = "org" $player.test2.childext = $sub $player.test2.childext.child1 = "org2" $playerold = $player ; make a copy of the whole map ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF); original nested value in $player $playerold.test2.child1 = "changed" ; edit a nested value in $playerold ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF) ; original nested value in $player changed ConsoleWrite("---------------------" & @CRLF) ConsoleWrite("player.test2.childext.child1 : "& $player.test2.childext.child1 & @CRLF); original level2 nested value in $player $playerold.test2.childext.child1 = "changed2" ; edit a level2 nested value in $playerold ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF); original level1 nested value in $player stayed the same ConsoleWrite("player.test2.childext.child1 : "& $player.test2.childext.child1 & @CRLF); original level2 nested value in $player changed

Hi there,
I have a problem using the latest two betas of au3stripper.exe.
Compiling my script using V17.224.935.6 works fine, the next two releases (18.624.1847.0 and 18.624.1847.1) show an error:
!==> *** ERROR: stopping process because include file not found :#include <INCLUDE_FILE.au3> !==> *** Checked these directories : !==> C:\Program Files (x86)\AutoIt3\include\INCLUDE_FILE.au3 !==> SCRIPT_DIR\INCLUDE_FILE.au3 !==> SCRIPT_DIR\INCLUDE_FILE.au3 !>18:42:00 --------------------------------------------------------------- !>18:42:00 Au3Stripper ended with errors, using original scriptfile.rc:999 !>18:42:00 --------------------------------------------------------------- Changing the include line according to the helpfile (using "..." for includes in script dir and <..> for includes in the au3-include-dir won't help!?
Greetings

Can somebody try to reproduce this bug?
It would be helpful to know if this issue appeares on other environments too.
Issue:
Sometimes values of certain keys will return empty even if expicitly assigned a value before.
Conditions:
Map is bigger than ~50 key/values pairs value is being worked with in a Function where a loop is iterating through the Map before retrieving the value there is a isMap/MapKeys/MapAppend/MapRemove check on the Map value. Dim $mMap[] ; Generate random key strings For $i = 0 To 100 $RndKey = "" For $i2 = 0 To 4 $RndKey &= Chr(Random(65,90,1)) Next $mMap[$RndKey] = 999 next ConsoleWrite("-----------1-------------" & @CRLF); Unpredictable blank values MapDisplay1($mMap) ConsoleWrite("-----------2-------------" & @CRLF); ByRef always works MapDisplay2($mMap) ConsoleWrite("-----------3-------------" & @CRLF); not in a function always works For $i In MapKeys($mMap) isMap($mMap[$i]) ConsoleWrite($i&": "&$mMap[$i]&@CRLF) Next Func MapDisplay1( $m_Map ) For $i In MapKeys($m_Map) isMap($m_Map[$i]) ;same problem with isMap($m_Map[$i]), MapKeys($m_Map[$i]), MapAppend/MapRemove but NOT with MapExists($m_Map,$i) ConsoleWrite($i&": "&$m_Map[$i]&@CRLF) Next EndFunc Func MapDisplay2( ByRef $m_Map ) For $i In MapKeys($m_Map) isMap($m_Map[$i]) ConsoleWrite($i&": "&$m_Map[$i]&@CRLF) Next EndFunc
The value is not lost or overwritten on the global map, only on the local map inside the function.

Hello Again! I previously stumbled upon a topic asking for maps datatype's instructions... I too wasn't sure what a map is until I tried it... So I am making this topic to help other newbies (and some oldbies) better understand the Maps datatype of AutoIt! Lets start!
A Note for Readers
The maps datatype is still in development and is currently in Alpha Stage (More Risky than Beta) and its unstable, so AutoIt can crash indefinably while using Maps! I can't guarantee if this will be implemented in stable versions, this is a fairly new thing to AutoIt coders & in my honest opinion I don't see any use for it Maps are the best datatype in AutoIt, Very Useful ... Not hurting anyone though . Also the maps datatype is DISABLED IN STABLE VERSIONS, So you need to install the latest beta version of AutoIt to make maps work . If you find any bugs while using a map, please report it in the Official Bug Tracker
Introduction To Maps
Maps are just like arrays, instead they use "keys" to access elements inside them... A key can be either a string or an integer (Other datatypes work too but they are converted to a integer [Equivalent to Int($vKey)] before assignment [Source]). Although Integers don't represent the order of elements in a map unlike in an array...
Declaring Maps
Its similar to declaring an Array:
; This is the only way to declare a map ; You must have a declarative keyword like Dim/Global/Local before the declaration unless the map is assigned a value from a functions return Local $mMap[] ; Don't insert any numbers or strings it! Simple, Isn't it?
Using Maps
Using maps is similar to arrays (again!):
Local $mMap[] ; Lets declare our map first! ; Adding data to maps is easy... ; This is our key ; | ; v $mMap["Key"] = "Value" ; <--- And our value! ; A key is Case-Sensitive meaning "Key" is not same as "key"! $mMap["key"] = "value" ; Not the same as $mMap["Key"]! ; There are 2 different ways to access an element in a map $mMap["Key"] ; 1st Method $mMap.Key ; 2nd Method Enumerating Maps
Its quite easy to enumerate through arrays but what about maps? how can I enumerate through them!?
#include <MsgBoxConstants.au3> ; Lets create our map first Local $mMap[] ; Lets add some information to the map, feel free to modify & add new elements $mMap["Name"] = "Damon Harris" $mMap["Alias"] = "TheDcoder" $mMap["Gender"] = "Male" $mMap["Age"] = 14 $mMap["Location"] = "India" $aMapKeys = MapKeys($mMap) ; MapKeys function returns all the keys in the format of an array Local $sProfile = "Profile of " & $mMap["Name"] & ':' & @CRLF ; We will use this string later For $vKey In $aMapKeys ; We use this to get the keys in a map :) $sProfile &= @CRLF & $vKey & ': ' & $mMap[$vKey] ; Add some details to the profile string using our map! Next MsgBox($MB_ICONINFORMATION + $MB_OK, "Profile", $sProfile) ; Finally display the profile :) It is easy as always
Multi-Dimensional Maps
Now now... I know that you are a little confused that how can an multi-dimensional maps exist... Although I am not 100% sure if its called that but lets continue:
#include <MsgBoxConstants.au3> ; Multi-Dimensional maps are just maps in a map Local $mMapOfMapsvilla[] ; This map will store an other map Local $mParkMap[] ; This Park map will be inserted in the Mapsvilla's map :P $mMapOfMapsvilla["Map Item 1"] = "Town Hall" $mMapOfMapsvilla["Map Item 2"] = "Police Station" $mMapOfMapsvilla["Map Item 3"] = "Shopping Mall" $mMapOfMapsvilla["Map Item 4"] = "Residential Area" $mMapOfMapsvilla["Map Item 5"] = "Park" $mParkMap["Map Item 1"] = "Cottan Candy Stand" $mParkMap["Map Item 2"] = "Public Toilet" $mParkMap["Map Item 3"] = "Woods" $mMapOfMapsvilla.Park = $mParkMap MsgBox($MB_OK, "Map Location", $mMapOfMapsvilla["Map Item 1"]) ; Will display Town Hall MsgBox($MB_OK, "Map Location", $mMapOfMapsvilla.Park["Map Item 1"]) ; Will display Cottan Candy Stand I am sure its easy for you to understand now
Frequently Asked Questions (FAQs) & Their answers
Q #1. Help! My code does not respond to anything (or) I get an "Variable subscript badly formatted" error on the line of declaration...
A. DONT USE F5 or Go, Instead use Alt + F5 or Tools -> Beta Run in SciTE (Make sure that you have Beta installed)
Q #2. Why are you using "m" in-front of every map variable?
A. Best coding Practices: Names of Variables
Q #3. What are "Elements" which you mention frequently???
A. This is a newbie question (I have no intention of insulting you ), so I guess you are new to programming. "Elements" are data slots inside a Map (or an Array), you can imagine elements as individual variable which are stored in a Map. You can access them using "keys", Please refer to "Introduction to Maps" section at the starting of this post
Q #4. Are Maps faster than Arrays?
A. You need to understand that Maps have different purpose than Arrays. Maps are designed to store data dynamically (like storing information for certain controlIDs of GUI) and Arrays are designed to store data in a order (for instance, Storing every character of a string in an element for easy access). If you still want to know then if Maps are faster, then the answer is maybe... Maps are *supposed* (I am not sure ) to be faster in addition of elements (while Arrays are painfully slow while adding or removing elements). Here (Post #24) is a benchmark (Thanks kealper! )
More FAQs coming soon! Feel free to ask a question in the mean while
