Case sensitive variables question [SOLVED]

Recommended Posts

Shanheavel

If you try below code:

Assign("Val",-45.961)
$sStr = "VAL: " & Eval("VAL") & @CRLF
$sStr &= "val: " & Eval("val") & @CRLF
$sStr &= "VaL: " & Eval("VaL")
MsgBox(32,"Variable",$sStr)

you can note that all results are the same.

I'd like to make case sensitive variables (I need this for some scripts), where VAL, val and VaL are different. It can be done with array functions, but it's slow and not smart. So I've a question. Is it possible to do this in any other way?

I'm waiting for an answer.

Shanheaval,

Really? Can you give us an example? :huh:

You state you need case sensitive variable names but don't explain why.

So, could you shed some light as to why this would be needed?

This is no 24 hours support forum. It's not impossible that you wont't get an answer at all.

@Melba23 and Jos

I'd like to work with standard system functions, constants and structures. They're case sensitive.

@water

I know this isn't forum with 24/7 support, but it would be nice to get fast reply (like now :)).

I experimented with Assign, EnvSet, DllStructCreate etc. All of them are case insensitive .

Could be me but still missing your point.

Show me an example where Case sensitive variable names are an issue for you.

AutoIt isn't case sensitive in regards to variable/function names. So, whatever it is that you think you need them for, AutoIt won't fit the bill. Although I greatly doubt you need case sensitive variable names, AFAIC I don't think any programming language NEEDS case sensitive variable names, nice to have, but it's almost never a need more than a want.

@Jos

I think we focused on the my point of view instead the problem. My English is hard to read, but I hope you can understand essence of my statements.

Returning to the topic, imagine that you've a list of USER32 library functions. From an ActivateKeyboardLayout to a wvsprintfW.

It looks something like this:

...
$MessageBeep = 0x7E431F7B
$MessageBoxA = 0x7E4507EA
...

and you want to assign the variable MESSAGEBOXA to 123. Of course, it'll fail, because you only overwrite the MessageBoxA.

This explain is good?

@czardas

I need to write my own preprocessor to AutoIt - closed source language? Is it a joke?

@BrewManNH

I didn't compare the amount, but I think the most programming language need case sensitive variable name (read C++ or FASM).

No, they don't need them, they HAVE them, that is not the same thing. Just because they have them doesn't make it a need, it makes it something you have to remember to work around when naming variables. Anyone that states they NEED case sensitive variable names and can't explain in simple terms why they need them, obviously doesn't know what they're talking about.

I'm not saying that your lack of skill in the English language is an issue, but you haven't come up with a single reason why you think you need case sensitivity.

As Jos pointed out, the OP needs to show an example of code that breaks because of case sensitivity.

No it was not a joke. You know how you want the code to respond. Write the code to process the input before it is sent to the closed source interpreter. Why is that a joke? It might be easier to write the code differently. Like everyone else around here, I don't understand your reasons for wanting to use case sensitive variables. So it's the best answer I can offer.

Shanheaval,

I am loath to join in this procession of "WTF?" posts but your example:

$MessageBoxA = 0x7E4507EA
... and you want to assign the variable MESSAGEBOXA to 123

is the worst excuse I have seen here in nearly 5 years for claiming AutoIt has a problem. Let me offer some reasons why I have a real problem in treating your complaint as a serious failing in the language:

- 1. MESSAGEBOXA is not a valid AutoIt variable, so you fall at the first fence. :(

- 2. You decide what to call variables, not AutoIt, so why not use another name which does not depend on case-sensitivity? What forces you to use $MESSAGEBOXA (note the proper syntax) or $MessageBoxA as the name of a variable within your script? Why not change one of the names? There is a very good "search and replace" function in SciTE to amend existing code. ;)

- 3. You still have not shown us a valid sample of AutoIt code in which case-sensitivity is an issue. And until you do, I will treat your complaint with the contempt it frankly deserves. ;)

So, any advance from your side? Any actual code you can show us that needs case-sensitivity? :huh:

Writing preprocessor to other programming language isn't bad idea, but I just do it. So I can't write preprocessor to preprocessor, because it will very slow.

You all ask about code of example. I can say only that I'm making some "tool" written in AutoIt, which convert code in my format to FASM. Latter uses case-sensitivity, first not. And it's hard to bring together both for me, so I asked you. The only thing I came up with is something like this:

...
$aValName[3] = "MessageBoxA"
$aValData[3] = 0x7E4507EA
...
$aValName[34] = "MESSAGEBOXA"
$aValData[34] = "bla bla bla"
...

Shanheavel,

In that snippet you are using "MessageBoxA" and "MESSAGEBOXA" as literal strings which are case-sensitive in AutoIt, so I still fail to see how the case-insensitivity of AutoIt variables poses a problem. :wacko:

If you do come across a case please do let us know so that we can hep you resolve it - but were I a betting man my money would be on you never producing anything viable in which case-sensitivity poses insoluable difficulties. ;)

I would say that depends on your method, and perhaps on the code content to a certain degree. How imperitive is it that you save half a second or even just a few miliseconds before the script runs? Anyway it seems superfluous to do this for anything other than an exercise. I suggest you think of a better alternative - one that's easy to code for.

Assign(StringToBinary("VAL"),-45.961)
Assign(StringToBinary("val"), 34)
Assign(StringToBinary("VaL"),1)
$sStr = "VAL: " & Eval(StringToBinary("VAL")) & @CRLF
$sStr &= "val: " & Eval(StringToBinary("val")) & @CRLF
$sStr &= "VaL: " & Eval(StringToBinary("VaL"))
MsgBox(32,"Variable",$sStr)

And the winner is... AZJIO!

Exactly what I was looking for. I tested and it works. This is why I love this forum. If nobody has to add then I think we can close the thread.

Thanks!
