I don't think the name map is misleading. It does exactly what a map
does. It maps a type Key to another type Value. A list maps an

Hash tables, as far as I know, are

True. I could optimize the current implementation a little. Now I insert and

I compared the performance of this generics map to a simple integer list.
The map was much slower and it also ate huge amouts of memory, 1.5 GB.

I also chose SynEdit for Lazarus Delphi converter for some reason. (I think it
was the first hit when searching regexp from Lazarus code base).
It works well.
I would guess the other choices work well, too.
About the speed difference: I don't believe there is any huge difference.
Please remember
Hi
Speed is important to me, but reg-expr features is important as well.
Actually, I want to include reg-expr as an alternative search mode in
my general-purpose file search unit.
Then the SynEdit's version of regexp should be fast enough.
SynEdit editor in Lazarus for example uses it and
Hi!
Well, we once had a prof who counted from 0. After he had drewn a large
diagram on the board he wanted to make sure that it was indeed 12 states
as stated in the caption. So he went: 0, 1, 2, ... , 11. Hmmm... I've
seem to have missed one. Let's count again: 0, 1, 2 , 11

I'm curious, why didn't you make it a class...wouldn't that have made it
nicer/easier to use and program?
+1
It should be a class, yes. Now you have loads of global functions.
The integer data type doesn't make much sense but your comment says it will be
changed to generics type. That sounds
Hi,
There are use cases for this.
A while ago I thinking about a string-hash table as a cache for strings.
I have done that. Then I needed to inspect the reference count for debugging
and configuration purposes. I didn't know there is StringRefCount() function
so I also counted the string
This is plainly wrong. When indexing a dyn. array, the compiler
generates the correct code to access the data, no more no less.
It would be possible to allow this syntax :
move(data ...
in addition to the current :
move(data[0] ...
There is no fundamental reason why it wouldn't be
Hi
The essential part is to have virtual constructor like in Florian Klaempfl's
example code:
t_mammal = class
public
constructor create (color : byte); virtual;
end;
and then...
t_pig = class(t_mammal)
public
constructor create (color : byte); override;
end;
.
Or was it only with function's string return value, I am not sure.
Anyway, after that I was careful to always assign my strings.
Maybe it is not true with FPC.
