Code: Select all
--
-- Name: Make Backup of document to !version
--
-- Author: Dennis Komeshak
--
-- Language: LUA Macro
--
-- Description: When the file is saved, this LUA macro wraps around cs-source-backup.exe
-- located in the WINDOWS directory. It passes the filename and cs-source-backup.exe
-- will write a copy to the !version directory. The filename is appended with the date
-- and time that the file was saved.
--
-- Example: SOURCE.COB will be saved as SOURCE-2019-07-27-133145.COB in the !version directory.
--
-- Installation: To configure this macro, for all document types, use the Options, Default Document Type
-- menu and attach the macro to the "File Save Prefix" trigger option. (e.g.)
--
-- Options|Default Document Type...|Triggers|File Save Prefix = $zud\zScript\cs-source.lua
--
-- To configure this macro, for a particular document type, use the Options, Trigger Options
-- menu and attach the macro to the "File Save Prefix" trigger option. (e.g.)
--
-- Options|Trigger Options...|File Save Prefix = $zud\zScript\cs-source.lua
