Posted: Tue Feb 04, 2003 11:14 pm Post subject: VDSLIST.dll bug |
|
|
I checked out the VDSLIST.dll contained in the VDSDLL 3 package.
There seems to be a bug in it, e.g.:
%%item = @lst(item,1,2)
always returns nothing.
But documentation states that
@lst(ITEM, <list name>{, <index position>})
returns the list entry at the current index position in the list named <list name>.
%%item = @lst(item,1) works normal.

and... Does %%item = @lst(item,1,3) work? Is there an item at
index position 2? _________________ FreezingFire

Sorry. Maybe I wasn't too clear about it. It's the syntax as such that does not work. Any item that
you try to retrieve by specifying the list index number in @lst(item,..,..) turns up empty.
The problem can be overcome by doing for instance
lst seek,1,2
%%item = @lst(item,1) instead.
Thats works OK. But I wanted to let Tommy know that something is wrong either in the DLL or
the documentation.

Another bug:
Documentation says:
@LST(MATCH, <list name>, <text>)
Returns 1 if <text> is found in the list named <list name>, starting from the current index position, otherwise this
will return nothing. If <text> is found, the current index position will be set to the position of the match.
However, if you run something like this
Code: |
repeat
if @equal(1,@LST(MATCH,1,%%search))
%%found = %%found@lst(NEXT,1)@CR()
end
until @null(@LST(MATCH,1,%%search))
|
you will end up in an eternal loop because even though the list index pos is advanced by @lst(NEXT,1)
then @lst(MATCH...) seems to always start from the top so if there's just 1 match in the file it will
keep on finding that item.

Bug No. 3:
Code: |
external vdslist.dll
lst create,1
lst add,1,Test1
lst add,1,Line2
lst add,1,Line3
lst assign,1,Two@cr()new lines
info #@lst(text,1)#
|
Try that code - should put two lines into the list, but instead the whole list turns out empty.

This may not apply to the VDSLIST.DLL since I haven't tested it lately, but
the actual LIST documentation for VDS explains that the LIST ASSIGN
command should be used like LIST ASSIGN,1,2... which assigns the contents
of 1 to 2. _________________ FreezingFire

Hey FF!
You're right of course about the VDS lists. But quoting from the VDSLIST.DLL
documentation:
Code: | LST ASSIGN, <list name>, <list name 2>
Copies the contents of the list <list name 2> to the list <list name>.
LST ASSIGN, <list name>, <text>
Adds the text <text> to the list <list name>. <text> mustn’t be equal to an existing list name. New entries will
start at @CR() characters in <text>.
|
BUG !! This last one will empty the entire list. Not even the new text will be there...

PS: Actually normal VDS lists can use the same syntax. E.g.
Code: | list create,1
list assign,1,Line1@CR()line2
info @text(1) |
will put 2 new lines into list 1. _________________ ~~ Alcohol and calculus don't mix... Don't drink and derive! ~~

I don't know whether this is bug No. 4 or a feature, but
@LST(MATCH, <list name>, <text>)
is always case-sensitive. Nothing mentioned about that in the documentation.

All of these problems should be resolved in the new work-in-progress VDSDLL 3. |

Grrrreeaatt! That would make things so much easier, especially because VDS itself cannot handle
lists above 100,000 lines
