Question

I would like to program productive and keep my FileSize very small. However I would like to know a few tips how do accomplish that.

举例来说,小案卷越好:

分别:

if .... =  1  then begin
 ...
end;

或

if ..... = inttostr(1) then begin
...
end;

或

if .... = inttostr($0001) then begin
...
end;

或

case of intvar
  1: ...
  2: ...
end;

Then there is something that I tried and I was surprised. I made another Unit in my project that stores Strings as constants and then I use the constant vars to replace the strings in my project. For some reason this raises my FileSize although I replace double used Strings as a var now.

Also is it better to store stuff in vars than put them directly into the code?! For example:

Function1(param1, param2, param3); // this code is used about 20 times in my project

如果我:

Avar = Function1 (param1,param2,param3); // Store this once in a var and then replace it

关于:

if ... = TRUE

或

if ....

如下:

if .... = FALSE

或

if not(...)...

为较小的档案制作节目的任何其他渠道?

提前感谢。

Answer 1

我很抱歉要bl,但你正在把车放在马上。

如果你真的想要知道如何使你无法执行,而现在又不知道你在具体事例中的法律差异将产生什么差异,那么,你就应当停止现在的到来,读/学习/实践,直到你更多地了解语言和汇编者。

然后,你理解,你的问题本身没有什么意义,正如你已经看到的所有有关意见一样。

the exact same source code can result in vastly different executables and different source code can result in the same executable, depending on the compiler options/optimizations
if your main goal is to micro-manage/control the generated exe, program directly in assembler.
if you want to know what is generated by the compiler, learn how to use the CPU View.
program for correctness first, then readability/maintainability
only then, if needed (implies using correct metrics/tools), you can optimize for speed, memory usage or file size (probably the least useful/needed)

很久以前,我就试图使方案尽可能小,因为它必须安装在一盘fl盘上(一只知道一米一只din。这个Splitter工具是在Delphi撰写的,规模约为50KB。

要想达到这一小点,就必须在没有许多Delphi的单位(特别是Forms/code>单位和所有提及该单位的单位)的情况下这样做。唯一的办法是将Windows-API直接用于全球倡议,而且可以想到现在这样做的理由,但出于兴趣。
