WeiDU fails when trying to modify hidden files

[AL|EN]

This code fails when engine.lua has "Hidden" attribute enabled (tested using clean Windows 7):

1. Set engine.lua as "Hidden" file in Windows
2. Try to install A1 component

Code: [Select]

BACKUP ~A1/backup~
AUTHOR ~A1~
BEGIN ~A1~
COPY ~engine.lua~ ~engine.lua~
   REPLACE_TEXTUALLY ~engine_name[ %TAB%]*=[ %TAB%]*".*"~ ~engine_name = "Baldur's Gate - Enhanced Edition Trilogy"~

Error:

3. After this error popups, weidu 'unhide' file (attribute "Hidden"  is somehow removed and the second try of installation will pass without problems.

I don't know what is the reason but the fact it exist is definitely not a good thing.

You've already posted about this and I've already said no.

To add more detail: this apparently happens because Windows only allows you to write to hidden files under particular circumstances. As far as I can tell, OCaml does not support the required Windows-isms to make this work smoothly.

[AL|EN]

If the weidu unhide file, could be possible to change error message just to get know what is the real problem?

I don't think I can give you anything better than the "something went wrong" message WeiDU delivers now. I'm not sure why the file is unhidden. For all I know, it's something Windows does after telling WeiDU it can't open the file like that, in which case I can't do much about it.
