Meta-magic
From metashell
"meta-magic" is a phrase coined by the metashell project owner, Justin M. Wray.
Origin
The origin of "meta-shell" comes from the first Devlog post, in which the project owner, Justin M. Wray, speaks about "meta-magic" being used to magically execute our applications.
Description
"meta-magic" is the separator between metashell and any other shell out there. With a little bit of "meta-magic" the shell determines the filetype and executes the correct application. Basically, "meta-magic" is the magic needed to preform the magical core functions of the metashell. Its the magic behind metashell.
Technical
metashell uses the libextractor library to preform the "meta-magic" functions. This library is used to gather information on a file and determine a filetype. Which in returned is magically used to determine the correct application. It can be interpreted that "meta-magic" refers to the code connecting those two functions, filetype and application.
