Submit code to codeforces from the command line, and other stuff (display solves for each problem, display standings).
In order to save the huge number of seconds needed to reach for the mouse during codeforces contests, I needed to be able to submit from the command line. There are many tools to do this for codeforces contests but I was unable to find an existing tool that allowed submissions to the codeforces gym for virtual contests, so I made this.
After being able to submit from the command line, I noticed that I was wasting too much time staring at the standings on codeforces. Now I waste less time (hopefully) by staring at the standings in the terminal.
Then I realized I would rather not navigate codeforces in my browser because looking for my mouse is a hassle, so now I can look at the number of solves for each problem in the terminal as well.

con
orgym
to set default contest or gym ID. Example:cf con 844
orcf gym 101482
ext
to set default file extension. Will be used when no file extension is given. (cf submit a
)submit
to submit code. Will try to guess problem. Batch submit allowed. Example:cf submit
orcf submit a.cpp
--prob
or-p
to specify problem. Example:cf submit code.cpp -p 844a
--watch
or-w
to Watch the status of submission after submitting it. Example:cf submit a.cpp -p 844a -w
peek
to look at status of the last submission. Example:cf peek
watch
to watch the status of the last submission if-w
was not used. Example:cf watch
login
to store login info (username and password), will prompt you to enter password. Example:cf login
orcf login <your handle>
info
to show stored handle and contest id. Example:cf info
time
to show time left in contest
Examples: cf submit code.cpp -p844a -w
standings
orst
to look at friends' standings. Example:cf standings
--contest
or-c
to specify the ID of the contest to look at. Example:cf standings -c 844
--verbose
or-v
to print standings with more info. Example:cf standings -v
--top
or-t
to look top contestants. Defaults to top 50 if-t
is not included, top 10 if--top
is included but no number is given. Example:cf standings -t 20
--all
or-a
to look at all contestants instead of only friends. Example:cf standings --all
--sort
or-s
to merge the solves of different rows belonging to the same handle. Will not merge two correct submissions on different rows. Example:cf standings -s
Examples: cf st -v -t7
or cf standings -c844 -v -a
problems
orpb
to look at the number of solves for each unsolved problem in a contest. Example:cf problems
--contest
or-c
to specify the ID of the contest. Example:cf problems -c 844
--verbose
or-v
to show solved problems as well. Example:cf problems -v
--sort
or-s
to sort problems by: number ofsolves
, orindex
(id
). Default sort is by number of solves (you do not need to use--sort
). Example:cf problems -s id
Exmaples: cf pb -v -s id
or cf problems -c100187 -v
test
to test code on input files. Suppose we want to test problema
. Thencf test a
will do the job. This will call./a < a*.in > a*.out
for each file named in the forma*.in
. Then it will comparea*.out
witha*.ans
ignoring differences in white space.
