nboard is like yourworldoftext.com, except its in a terminal.
|
|
|
|
how to get started:
|
|
if you do not want to start your own then you can
|
|
`git clone /home/xfnw/.nboard .nboard` or if you want to start fresh
|
|
make a directory '.nboard' in your homedir and put a json
|
|
file named 'nboard.json' in it, and stick an empty dict
|
|
inside it, eg '{}'.
|
|
|
|
i would reccomend tracking it with git and adding remotes for other
|
|
people who use nboard, and then you can `nboard pull` to add them all together.
|
|
|
|
navagation:
|
|
use the arrow keys to move arount
|
|
once you are in the place you want, you can start typing!
|
|
|
|
hold ctrl while pressing the arrow keys to go faster
|
|
|
|
bugs and stuff:
|
|
please report any bugs to ~xfnw on IRC, anywhere you can find him, or
|
|
on the tildegit page, https://tildegit.org/xfnw/nboard
