Guest Posted February 28, 2017 Share Posted February 28, 2017 (edited) My tip is that Global variables is your best friend as long you throw to the garbage the approach of making variables names short as possible and you know what you are doing.. Of course, you do not have to accept it. This is what I got after a long experience(small with C++) and deep thought. My suggested and new coding style is this: Use globals variables as many as you need. It may be that the more global variables, the more It is better (only if you know what you are doing!! and for you to know what you doing you need to follow the next rules) Don't use 'g_' . If you do 1), then there is no logic and justification to use this. it will make the code ugly without any benefit. instead of using 'g_', just don't try to think about short name. Think about long name according to the rules of 4. (Only about global variables) Instead the prefix 'g_', the prefix need to be about the scope of the variable itself: If the variable is related to specific function group (so the functions of that group are named this way group_*<FunctionName>) , then the prefix of the variable will be 'group_' and not 'g_'. (This is true according to my personal experience:) You should accept the fact that the Variables names are going to be long and live with this. If you want to easly improve the script. You can make the name shorter but only according to these rules Make the prefix(s) of the Variable shorter BUT only in this way: for example: If the variable have 2 prefixs: 'SettingsWin' -> 'SubWindow' then the variable name will look like this $SettingsWin_SubWindow_SomeVar. This way you should shorten it: $SetWin_SubWin_SomeVar OR $SeWi_SuWi_SomeVar. BUT NOT like this: $S_S_SomeVar. You never should shorten the prefix to one character. The minimum characters for prefix is 2 (Not including the '_') . You can use this font mode:It will shorten the names significantly if you use "_" a lot of times. Use the "_" as a line break. example: Instead of writing like this: MsgBox(0,'Title','Text',1000) You can write like this: MsgBox (0, _ ;flag 'Title', _ ;title 'Text', _ ;text 1000) ;timeout This way, when you use long variable name, it will not hurt you. And at the same time, you get better understanding about the parameters of the function. Divide the code into multiple files *.Globals files - the files that only the globals variables are written there Standard files - the files where you write the code Very important: Tou must to include first the *.Globals files. ONLY then you can include the other files. Very important: You need to keep as much as possible to write any global variable in the *.Globals file it belong to AU3Stripper: You have no choice - If you use this coding approach, you need to use AU3Stripper at the compile time. If the Variables and the functions names are long, it will hurt the performance.. it is not compile to machine code.

czardas Posted March 2, 2017 Share Posted March 2, 2017 (edited) That is your idea of good coding practice and, although you made some good suggestions. it does not necessarily tally with everyone else's idea. Using global variables has good and bad consequences. I personally avoid using them as much as possible. Avoiding global variables frees up memory and side steps several issues that may sometimes occur.

Guest Posted March 2, 2017 Share Posted March 2, 2017 Of course, everyone will do what is good for him. Quote Avoiding global variables frees up memory and side steps several issues that sometimes occur. This is one the weak reasons why avoid globals. This is not 1990.. Memory of the PC is not a big problem now. If you avoid globals, you also avoid their very good benefits. If the only reson for that is problem mostly belonged to the past, then it is a bit does not make sense to do it..But if you have more reasons why to do it and good ones, then it is fine. If you write it in very very organized way ( Multiple source code files , good names with prefixes for functions, variables and source code files), you can easaly add functions of this type: "<function>_FreeMem" Inside each "*.Globals" file ( I mentioned to do it in 6) ), aftere you worte the declaration of the global variables, there in this file just add function with this name <GroupName>_FreeMem() or <SomeGroupName>_<SomeVariablesType)>_FreeMem() In that function, set every variable to it's zero state ( Usually should assign the value 0 but sometimes you may want to assign some empty array) Link to comment Share on other sites More sharing options...

mLipok Posted November 4, 2017 Share Posted November 4, 2017 (edited) hm... as I remember here (in this topic/thread) was not discused about: "variable meaningful titles/names" Also on AutoIt Wiki:https://www.autoitscript.com/wiki/Best_coding_practices#Names_of_Variables There is no mention about "variable meaningful titles/names". For example in this Wiki page there is: For $i = 1 To 10 $g_vVariableThatIsGlobal &= $i ; This will return 12345678910 totally wiping the previous contents of $g_vVariableThatIsGlobal Next And for this little "for to next" loop I do not see any needs to change it, especially that in this example the loop is inside a small function. But for some time, I have tried in my UDF's to make the variables "significant titles". ; my old coding habbits For $i =1 To $aUsers[0][0] ...... ...... ...... ...... ...... ...... ...... ...... ...... $aUsers[$i][....] ...... ...... ...... ...... ...... ...... ...... ...... ...... Next ; my current coding style For $iUser_idx =1 To $aUsersList[0][0] ...... ...... ...... ...... ...... ...... ...... ...... ...... $aUsersList[$iUser_idx][...] ...... ...... ...... ...... ...... ...... ...... ...... ...... Next ; my old coding habbits For $oUser In $oUsers.count ...... ...... ...... ...... ...... ...... ...... ...... ...... $oUser.value ...... ...... ...... ...... ...... ...... ...... ...... ...... Next ; my current coding style For $oUserNode_enum In $oUserNodes_coll.count ...... ...... ...... ...... ...... ...... ...... ...... ...... $oUserNode_enum.value ...... ...... ...... ...... ...... ...... ...... ...... ...... Next Thanks to them, I avoid many problems with analizing old code. Even when I try to understand my own old code (older then 3 years), I start with rewriting variable names. And then I use Au3Check, and finally i start to understand what is going on in this code. What you think about such convention - I do not mean exactly about the suffix _coll, _enum and _idx but generally about the concept to use "variable meaningful titles/names" ?

Danyfirex Posted November 4, 2017 Share Posted November 4, 2017 hello I'm not a too good in coding practices. But I try to use variable meaningful titles/names when I think Its required. expandcollapse popup;~ If Its for some Internal array manipulation I use something like this ;Also When things are too obviously For $i = 1 To $aArray[0][0] ...... ...... ...... ...... ...... ...... ...... ...... ...... $aArray[$i][....]...... ...... ...... ...... ...... ...... ...... ...... ...... Next ;~ If Is something of the main script where I know I use many For statements in a function ;if Is a 2D Array I use some meaningful const Index Local Const Enum $eNAME, $eEMAIL, $eADDRESS For $iIndex = 1 To $aUserInfo[0][0] ...... ...... ...... ...... ...... ...... ...... ...... ...... $aUserInfo[$iIndex][$eNAME]...... ...... ...... ...... ...... ...... ...... ...... ...... Next ;when I work with many GUIs I use something like this for may globals #Region GUI Main ;here some relevant information Global $g_MIdListViewUsers, $g_MhListViewUsers, $g_MIdtxtClientName, $g_MIdbtnAccept #EndRegion GUI Main #Region GUI Report ;here some relevant information Global $g_RIdListViewUsers, $g_RhListViewUsers, $g_RIdtxtClientName, $g_RIdbtnAccept #EndRegion GUI Report ;I think when I use object is enough somethig like this For $oUser In $oUsers.count ...... ...... ...... ...... ...... ...... ...... ...... $oUserCredentials = $oUser.GetCredentials ...... ...... ...... ...... ...... ...... ...... ...... For $oUserCredential In $oUserCredentials ...... ...... ...... ...... ...... ...... ...... ...... Next ...... ...... ...... ...... ...... ...... ...... ......

Earthshine Posted November 6, 2017 Share Posted November 6, 2017 (edited) pro tip. don't ever use DIM also, lots of global variables can get you into trouble in my experience. I prefer to pass parameters and set properties meaningful variable names are good too if others can read your code and understand it without lots of comments, you are doing it right.

Earthshine Posted December 8, 2017 Share Posted December 8, 2017 (edited) I use Global sparingly, in all languages. don't be a pig and eat up all the resources, plus, it's EASY to hose yourself. Using tons of globals is and ALWAYS WAS stupid. it is the LAZIEST thing you can do. DON'T DO IT! as few globals as necessary and that's it. Use constants for things that don't change globally as well. Autonomous functions contain their own variables, LOCAL vars, the way it should be. If your code is modifying vars in many source files, you can hose yourself without realizing it Edited December 8, 2017 by Earthshine My resources are limited.

Skysnake Posted December 9, 2017 Share Posted December 9, 2017 (edited) From here https://www.autoitscript.com/forum/topic/191475-good-coding-rules-was-case-statement-structure/ By @LarsJ The rule is that Case statements with most events should be in top of the list. Explained by @jchd It isn't a rule, but something you can consider in any on-the-fly interpreted language. Consider this simple sequence: If <Condition> Then [13,000 lines of code] Else [Action] End It's obvious that, unless a form of compilation has taken place which can jump direct to [Action] when <Condition> isn't met, the interpreter will have to read and ignore 13,000 lines, something which wastes time. Hence if you expect the false branch to be significantly more frequent than the true branch, you should swap them and negate Condition. Contributed by @Earthshine Follow Modular design patterns in general. Split things into small autonomous units. Never glom everything into a monolithic structure. (this one is important. Having one place to edit in case of changes instead of many files to edit. maintainability) Use good meaningful variable names Don't get carried away with macros, not to say don't use them Keep functions small, over 50 lines and you need new supporting functions (this works well with C/C++/C# but not sure if applicable to AutoIT and otehr scripting languages, but I try to do this with AutoIT. Most of what makes my functions longer are just logging if they get long in AutoIT cause I am a logging fool Don't follow the Single Entry Single Exit nonsense bullcrap either. If you run into a condition you need to break from the function, then do it Don't use GoTo statements (obviously they lead to spaghetti logic that can't be maintained) Use Constants for strings and stuff that does not change. that way, when something needs to change, it changes in one spot, not many never send an IF to do a SWITCH's (case) job Edited December 9, 2017 by Skysnake Earthshine 1 Skysnake Why is the snake in the sky?

mLipok Posted October 20, 2018 Share Posted October 20, 2018 (edited) On 7.01.2013 at 2:24 AM, Mat said: DRY and KISS, fail fast, SoC and single responsibility... Most of those are common sense and apply not just to programming. This on the other hand is a bit like the bible. You aren't expected to always follow it literally, stoning is generally frowned upon by modern society. Single entry and exit (SESE). Usually overlooked with good reason but can be important, a GUI loop that looks like this is not good: While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd This would be better: While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd Usually there are multiple places in the loop that should end the GUI (a cancel button, an action completing etc). If you were to add resources that need freeing, the second design means that code can go after the loop and be guaranteed to execute. Same applies for functions. Bad: Func Foo($i) If $i < 12 Then Return "Foo" Return "Bar" EndFunc Better: Func Foo($i) Local $ret = "Bar" If $i < 12 Then $ret = "Foo" Return $ret EndFunc You can now add code that will always be executed immediately before returning from the function (like freeing resources). I'm not saying go for it and rewrite all your scripts like this. Trying to can result in larger and more unreadable code. But bear it in mind when you write your code. Do you still follow this "rule" after these five years or have you changed your approach to this matter ? As to mentioned by You GUI concept I fully agree even more. My experience has brought me to the point where most of my programs have already been moved to such a structure as below: expandcollapse popup#cs some header: includes, script settings, glablas, enums etc.... #ce #Region - INIT / MAIN / EXIT _Init() _Main() _Exit() Exit ; one exit point Func _Main() #cs some code .... #ce While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop ; exit MAIN LOOP Case $1 ; any other code or function call Case $2 ; any other code or function call ........ Case $xyz ; any other code or function call EndSwitch WEnd ; some GUI CleanUp Return ; from _Main() to "GLobal Scope" EndFunc ;==>_Main Func _Init() ; some function sets to init program EndFunc ;==>_Init Func _Exit() ; some function sets to CleanUp - before Exit EndFunc ;==>_Exit #EndRegion - INIT / MAIN / EXIT #Region - FUNCTIONS ; any other functions #EndRegion - FUNCTIONS But with regard to the method of leaving the function, my experience from the last few years, directed me in a different direction - I will try to describe it in the next few days. If I went the wrong path, you will be able to correct me.

I generally do something like this: Instead of this: Global $gArg1 = True, $gArg2 = False Func _main() _1of2($gArg1) _2of2($gArg2) EndFunc Func _1of2($vParam) ; some algorithm EndFunc Func _2of2($vParam) ; some algorithm EndFunc Try to do something like this: Func _main() Local $aArgs[2] = [True, False] _1of2($aArgs[0]) _2of2($aArgs[1]) EndFunc Func _1of2($vParam) ; some algorithm EndFunc Func _2of2($vParam) ; some algorithm EndFunc This is the simplest example I can think of. Instead of using global, try to use local variables. I just started messing around with the AutoIt3Wrapper Directives last night and enabled one from, I believe, Au3Check that showed me a warning I had not seen before. I usually place a few Global variables at the top of my script like $Title which is what I use for MsgBox() or anything else where one of the parameters is a window title (it makes little sense to pass that as a function parameter). Otherwise, my philosophy is to be conservative when it comes to creating Global variables, and instead try to use Local variables and pass them to functions as arguments. That is what I have been doing in AutoIt forever. My code would look like this (borrowing your example and modifying it to my structure): Local $gArg1 = True, $gArg2 = False _1of2($gArg1) _2of2($gArg2) Exit Func _1of2($vParam) ; some algorithm EndFunc Func _2of2($vParam) ; some algorithm EndFunc I have a bachelor of science and a masters in Computer Science, and one of the concepts drilled into my brain from years of object oriented programming is to keep member variables private so that they cannot be manipulated in any way other than through the object’s built-in setter methods. This way you enforce the integrity of the member variables’ contents. So, that probably explains why I avoid global variables - I prefer that functions “properly” manipulate Global variables, and making a variable local helps enforce that. So, imagine my surprise when yesterday I ran sample code like the one I posted above and it warned me that I was declaring the two variables as Local but they were technically in a Global scope. I understand now why that is; all of this time I have been treating AutoIt’s global space (for lack of a better term) as the equivalent of main() in other languages, but that’s incorrect. So, if I want to stick to my philosophy of minimizing the use of Global variables for the reasons I stated, I need to adapt my program template to look like your second example, where you explicitly recreate the concept of main(). Of all the years of AutoIt code examples I have seen, I can probably count on one hand the number of times I have seen anyone explicitly recreating main() to enforce this. I think this should be emphasized in discussions concerning usage of Global variables in AutoIt. Func _main() Local $aArgs[2] = [True, False] _1of2($aArgs[0]) _2of2($aArgs[1]) EndFunc Func _1of2($vParam) ; some algorithm EndFunc Func _2of2($vParam) ; some algorithm EndFunc Link to comment Share on other sites More sharing options...

That's well documented in the help file under the Local/Global keyword explanations. Anything declared in the Global scope regardless of the keyword used (local/global/static) will be a global variable. AutoIt has 2 types of variable scopes, Global and Local, there's no file scope, there's no loop scopes, etc. Just the 2.

I read that numerous times throughout the AutoIt documentation, but for some reason it didn’t register in my brain properly until I enabled more verbose logging. I was just suggesting that another way to drive that point home would be to include @czardas example code that shows how you can mimic the behavior of other languages and how they treat variable scopes by calling a main() function. Obviously, you don’t HAVE to do it that way, but in this thread people made some valid points regarding best practices for global and local variables; I was just agreeing with czardas that using main() like that was a subtle, but effective, way to allow one to use global variables in the global scope and create local variables outside of the global scope but could still be used through the script. Basically, trying to compare and contrast the AutoIt approach with other languages as another way to reinforce what you had quoted from the documentation.
