( Using 2.02~beta2-7 from Debian Unstable )
I have tried to write some cfg files to kind of organise them as
libraries but it does not work as expected.
It seems as the sourced cfg files are being interpreted.
Here below you will find the overall idea in an theoric example.
Attached you will find an actual code (although you are missing some
pieces from Super Grub2 Disk).
When selecting the "Boot manually..." submenu (not when trying to run
one of their options) I am getting these errors:
BEGIN
error: syntax error
error: Incorrect command.
error: syntax error
error: Incorrect command.
error: syntax error
error: syntax error
error: Incorrect command.
error: syntax error
error: can't find command `searchindevice'
FATAL: int13_cdrom: function 42. Can't use 64bits lba
END
searchindevice is a function which it's sourced in main.cfg so it should
be detected ok.
But anyways... the run_option function is being interpreted while I do
not want it !!!
I have also tried to replace source command by extract_entries_source. I
get different output but the same problem, the sourced file is being
interpreted (I mean it is being run).
Thank you.
