TF_GetData() bug about tf

[hi5]

You don't use TF_GetData() in a script on its own. TF_GetData is called by all other TF functions to test if a variable or a file has been passed on to a TF_... function.

That particular line/error message is shown if a user makes a syntax error:

TF_...(! "file.txt",...) vs TF_...("!file.txt",...). The ! before a filename is used to write back the result of the TF function to the source file instead of a copy (file_copy.txt). I noticed that some users tried to use it like ! "file.txt" instead of "!file.txt" and I show the MsgBox as a reminder.

I can read/work with a file with one line containing "000000" without any problems.

What function are you using and how are you calling it, if you post it I might spot a syntax error (below each TF command there is a short example in the readme.md

TF_GetData() is called first in many user function.

msg =
(
000000
)
MsgBox % TF_TrimLeft(msg, 1, 1, 3)
— Error msgbox.

msg =
(
C:\users\desktop.ini
)
MsgBox % TF_TrimLeft(msg, 1, 1, 3)
— I get 1 here, because I have this file on disk.

msg =
(
!C:\
)
MsgBox % TF_TrimLeft(msg, 1, 1, 3)
— Error msgbox.

IMHO, from such type of function I expected behavior like SubStr().
No hidden parameters, no undefinied try read file, no error msgbox.
A good tool should be simple.
Of course, I understand that it's too late change it here.

Sorry but only the last one gives an error message, the first two work fine here.

Your second example should have created a file C:\users\desktop_copy.ini, it should be there.
The 1 indicates it hasn't been able to make a backup - There is little point in using MsgBox with files as, well it writes back the result to a file and does NOT return the changed content to a variable which you can display in a MsgBox.

The last one tries to read a file "C:" which of course doesn't exist (there is no such file) so it gives an error message saying it can't read it. You can pass on a variable as a filename which is what you are doing here in the second and third example.

So as far as I can see: no bugs and it works as intended.
