Functions ¶
func Init ¶
Init initializes the extensions, can be called multiple time safely but should really be called only once before using GROL repl/eval. If the passed Config pointer is nil, default (safe) values are used.
func MustCreate ¶ added in v0.63.0
Types ¶
type Config ¶ added in v0.41.0

HasLoad bool // load() only present if this is true.

LoadSaveEmptyOnly bool // Restrict load/save to a single .gr file inside the current directory.
UnrestrictedIOs bool // Dangerous when true: can overwrite files, read any readable file etc...
}
Configure restrictions and features. Currently about IOs of load and save functions.
