## Dependencies
|
|
|
|

|
## Quick Start
|
|
|
|
1. Find a contest:
|
|
|
|
```
|
|
:CP pick
|
|
```
|
|
|
|
2. View the problem:
|
|
|
|
```
|
|
:CP open
|
|
```
|
|
|
|
3. Code and test
|
|
|
|
```
|
|
:CP run
|
|
```
|
|
|
|
4. Navigate between problems
|
|
|
|
```
|
|
:CP next
|
|
:CP prev
|
|
:CP e1
|
|
```
|
|
|
|
5. Debug and edit test cases
|
|
|
|
```
|
|
:CP edit
|
|
:CP panel --debug
|
|
```
|
|
|
|
6. Submit:

```vim
|

:help cp.nvim

|
|
for the setup in the video shown above.
|
|
|
|
## Motivation
|
|
|
|
I could not find a neovim-centric, efficient, dependency-free, flexible, and
|
|
easily customizable competitive programming workflow that "just works"--so I
|
|
made it myself. I conferenced with top competitive programmers at Carnegie
|
|
Mellon Univerity and the University of Virginia and covered their (and my) pain
|
|
points:
|
|
|
|
- Scraping: contests are automatically loaded asynchronously
|
|
- Test Case Management: test case editor (`:CP edit`)
|
|
- UI: both `run` and `panel` layouts cover common formats
|
|
- Extensibility: snippet plugins, compilation, etc. are left to the programmer
|
