possible solutions to array and string incompatibilities

Recommended Posts

hi.

the array-related functions don't quite match each other when it comes to [0] like stringsplit() whicdh is 1-based and strings which are 1-based and _Array which is always 0-based, and dimensioning the array, or a different array type should have been developed that can work with StringSplit() and the [added?] _Array functions with more stringsplit() compatible definition about array size (using [0]). or something. need more compatibility.

there also needs to be a way to mass-initialize an array in the same compatible way without having to resort to

Dim $arr=StringSplit("1,2,3,4",","),$i

for $i=1 to $arr[0]

    $arr[$i]=int($arr[$i])

next

when it would be easier to do it C++ initializer_list style like

Dim $arr={1,2,3,4} ;would be more convenient, especially for multiline if didn't require _ due to comma

or

Dim $arr1=_ArrayNew(true, 1, 2, 3, 4) ;1st arg value true should cause $arr1[0] to be the number of elements, otherwise, will be 1st value in list, which is 1

Dim $arr2=_ArrayNew(true,"abc","def") ;number of args should make no difference, 2 or 200

I don't see anything in the documentation on this kind of feature, and I desperately need it..

Boolean:

there needs to be string to bool and bool to string conversion functions, as well as StringIsBool(), maybe you prefer to call it Boolean like VB. it should use case-insensitive string comparison to check if the string is "true" or "false" and if it's neither, return failure and/or throw set an error.

$varargs:

functions with variable number of arguments would also be handy if it's not already there. where this comes in handy is doing sprintf, vsprintf, printf or format type of statements, making an _Array function for initizliaing an array. I was looking at the way teh language handles variable arguments, and it's pretty fixed, not variable. could a more variable method be made that allows for byref variables that are not optional, and optional arguments that can be treated as byref, using something like varargs or some special variable (how about $varargs) that makes one argument the varargs variable and [0] the number of elements?

VB has I think provisions for a variable number of arguments if you are using that as a ruler. I could look it up if you are interested to find out. the manuals are online.

Example:

func somefunc(byref $arr, $str, $someint,  byref $varargs)

    if ($varargs[0]>=2) then

        $varargs[2] = "somestring" ;pass data back

    endif

    for $i=1 to $varargs[0]

        $arr[$i] = $str & $varargs[$i] & $someint

    next

endfunc

I need to know a consistent and easy way to know the array size at any given time, and arrays and strings are inconsistent throughout the language, so that code requires extra hard thinking to engineer and to do language conversions.

a couple of funcs are misnamed and are misleading actually.

_ArrayPush() is not a push, but would more accurately be called _ArrayShift().

_ArrayAdd() is well-named, but should be aliased as _ArrayPush().

seeing the functions misnamed confused me at first. nobody needs that when they are trying to get work done, wastes precious time.

C++ has some nice functions for stack and deque stuff, they are: push_front(byref $arr, $varargs, $index=1), push_back(byref $arr, $varargs), pop_front($index=1) which temporarily saves the element at $index, deletes the element and returns the saved value, pop_back() which temporarily saves and deletes the last element and returns the saved value. however what could be made better with c++ is pop functions could return the element of the array from front (first element or at given position). or back (last element). front_top($index=1) which returns element at index, back_top() which returns the last element.

are classes and easier structures coming to this language at some point? woiuld be really nice to OOPify my code when needed.

easier structures would be very very nice.

Boolean assignment and Boolean expression assignment:

btw, Boolean array init as it is now is also not easy. should be a 1-liner or optionally a multiline array init:

#include <Array.au3>

Dim $arr=StringSplit("true,false,false,true",","),$i
for $i=1 to $arr[0]
    $arr[$i]=Bool($arr[$i])
next
_ArrayDisplay($arr)

add this to your basic functions:

func Bool($s)
    if ("true"==StringLower($s)) then
        return true
    elseif ("false"==StringLower($s)) then
        return false
    elseif (true=$s) then
        return true
    elseif (false"=$s) then
        return false
    elseif ($s) then
        return true
    elseif (not $s) then
        return false
    else
        ;set error here
        return 0;
    endif
EndFunc
func StringIsBool($s)
   return ("true"==StringLower($s) or "false"==StringLower($s))
endfunc

jmichae3,

Any more complaints? :huh:

I have just looked back through your posting history for the past few years and apart from this thread where you blatantly ignored the Forum rules, you have only posted to complain about the language and how it does not meet your expectations and differsin some respects from other languages you know. I do wonder why you keep using AutoIt at all seeing it causes you so much grief. ;)

Atleast it's a long post and not just "this sucks", I see it as constructive critisism.

People talk differently, and he may not mean it as bad as you hear it.

jmichae3,

Also if one start examining your prose and attempted examples, one wonder which language you're actually familiar with.

Feel free to implement your own language.

I saw some missing language pieces and was trying to fill them in.

I was trying to help by at least adding some functions. wasn't trying to offend anyone (looks like I have by submitting patches).

as far as writing my own language, I haven't written code for a syntax tree in 20 years, so it's out of my league without a another class, and those are hard to come by when you have already gone though it.

books just aren't quite good enough to explain the whole thing. :-/

well, I like improving my own code, as long as some functions don't get really huge and nearly unmanageable.

don't know about other folks.

hey - free code. go for it.

if it's only one guy maintaining the code that can be rough on a guy's head when code gets to a certain size - wrapping your brain around 1M LOC is hard. and sometimes, looking at other people's code is hard too.

but I digress.

Most languages these days use zero based arrays, a lot of older languages used 1 based. So, at least AutoIt is consistent in that it matches today's languages. As to strings being 1 or zero based, the results are all over the place for today's languages as there's no real consistency on that.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
