At the moment, unfortunately Foldit doesn't offer any possibility to export you scripts, so we have to improvise.
The following text is for ex- and importing Lua scripts with NOTEPAD++
NOTEPAD++ is an open-source and very comfortable Text-Editor with many functions, provided by SourceForge.
You can download it here:
http://sourceforge.net/projects/notepad-plus/files/
Before you start, I recommend you to have a look at Lua Export and Import of Scripts using Text and HEX editor before.
How to do it:
Download and Install NOTEPAD++
Search for the all.macro-file as described at 3 in the other article.
Copy all.macro into an own folder
Start NOTEPAD++
Open all.marco with the File tab (Ctrl-o)
Click replace in the Search tab (Ctrl-h)
Deactivate "in selection" checkbox
Click search mode: extended
and replace \\n by \n
Click Replace all
Click search mode: normal
replace \ by nothing
Click Replace all
Your script is now ready to be edited as well as inserted into FoldIt again
