Native bash (bounded) last command correction, inspired by thefuck
fuckfind the name of the executable with the minimum levenshtein distance from the believed typo of the last command as the best guess. The believed typo of the last command is found by running that command once more and taking<COMMAND>from the string<COMMAND>: command not found
In order to use the C implementation of levenshtein distance, use
make distance
In order to retrieve the exit status of the last command, we cannot detach a child process for executing fuck, therefore immediately after trying to execute a typo, use
source ./fuck
from where fuck is located (the same directory in which distance.c must also be located)
$ asdf asdf
No command 'asdf' found, did you mean:
Command 'asdfg' from package 'aoeui' (universe)
Command 'sdf' from package 'sdf' (universe)
Command 'sadf' from package 'sysstat' (main)
asdf: command not found
source ./fuck
Last command: asdf asdf
Typo: asdf
Best replacement found: __ports
__ports __ports
Note it was purposely made that the last line would not get executed but just printed to the screen for the user to execute themself.
