This is a text editor application made by Manik Panwar
for the course 15-112 Fundamentals of programming and
computer science at Carnegie Mellon University,
which you can use to edit text documents and write code.
Not only can you do this on your own
machine but you can also collaborate
with friends live on different computers
through the internet and edit the same
text documents; all the while commenting
and annotating the text which automatically
shows up on your friends computer.
Apart from all the general text editor features
this also supports syntax highlighting for
all major languages, autocompletion(which show up
in the suggestion box), autoindenation,
auto parentheses completion, spelling correction,
dynamic python error detection, multiple text editor
color schemes and live collaboration with
others on other machines. For collaborating with
a friend you can either create a server and ask
your friends to join your server or
join an already running server. All you have to
do now is choose a language from the syntax menu,
choose your color scheme and preferences, set up
collaboration with a friend, and get started on
that 15-112 inspired project you are now about to do!
