Implement Clear

[zshzero]

Address issue #69

It is just a one-line simple code

[GrayJack]

Can you implement these features too? That would be awesome!!

-T TERM     use this instead of $TERM
-x          do not try to clear scrollback

I use them quite a lot, and know some people that uses it as whell

Also, use the git message formatting for future commits

ok... correct me if i am wrong...
-> -x option does clear the screen and lands to the line next to the prompt
-> -T $TERM option clears the whole terminal (Can we just make it -T ?)

[GrayJack]

Yes, -x does that, but it allows the person to scroll back
My output when I do clear -x

clear -x | hexdump -C
00000000  1b 5b 48 1b 5b 32 4a                              |.[H.[2J|
00000007

The -T option let you choose a TERM to clear, while absent the utility clears $TERM, that means, the current one

[zshzero]

ok... And my output was

$ clear -x | hexdump -C
00000000  1b 5b 48 1b 5b 32 4a                              |.[H.[2J|
00000007
$ clear | hexdump -C
00000000  1b 5b 33 4a 1b 5b 48 1b  5b 32 4a                 |.[3J.[H.[2J|
0000000b
$ clear -T $TERM | hexdump -C
00000000  1b 5b 33 4a 1b 5b 48 1b  5b 32 4a                 |.[3J.[H.[2J|
0000000b

Am i good to go ?

[GrayJack]

In that case just implement the -x, -T could be a feature for the future
