| %% move cursor to beginning of the line | |
| io:format("\e[H"). | |
| %% clear the console | |
| io:format("\e[J"). | |
| %% both | |
| io:format("\e[H\e[J"). |
after running some code later, everything that was cleared is revealed again
this actually causes the shell to emit ansi/vt control codes, where the user's terminal may or may not choose to respond. that's why scrolling "fixes" it, is that erlang has no idea that happened, and is faithfully repainting.
you can verify by setting your interpreter to dumb tty and trying this. nothing will happen.
io:format(os:cmd(clear)).
congrats tudrax
io:format(os:cmd(clear)) works!!!!

@laxmikantG Use the output of os:cmd("clear").
For me, io:format("\e[H\e[2J").
