write to file / edit script

[robm80]

open file "d:\foo.txt"
write tResult to file "d:\foo.txt"

This gives no problem when "d:\foo.txt" is empty. But when foo.txt is not empty yet: how to script that file empty

Why I have to wait 5 seconds at least, when clicking edit script
Is there no other way to edit a script?
In my previous programmer live you could rightclick a button for that

You can simply write empty to the file. Please read the dictionary under the "write to file" command for the several options associated with this. Look closely at the comments, and experiment with these.

I edit controls by holding down "Cmd-Opt" and clicking on the control. You can also use the inspector, or execute a command "edit script of object...". I have no idea why there should be any delay. Which method are you using? The inspector? Anyone else ever see this delay?

Use another method:

Code: Select all

put tResults into URL  "file:d:\foo.txt" 

It will be the standard Livecode syntax.

Sorry,
both advises do not solve the problem.
In the dictionnary there is no such line to empty an opened file.

What happens if you close the file (with the "close file" command), open it, and then write to it?

In the dictionnary there is no such line to empty an opened file.

This way:

Code: Select all

put empty into url "file:d:\foo.txt" 

[robm80]

Code: Select all

close file "d:\Livecode\Lijsten.txt"
   open file "d:\Livecode\Lijsten.txt"
   write empty to file "d:\Livecode\Lijsten.txt"

no reaction

Hi Rob,
Just a small missing thing;

Code: Select all

 open file "c:\Livecode\Lijsten.txt" for write

Just change that line in the above code and it all works (with a close file as a last line).

Both do it very well
Which one to choose

Lot of thanks
