nvim

My Neovim config. Lazy-loaded with lazy.nvim, everforest colorscheme, built around LeetCode/competitive programming in C++ and Python.

LeetCode Features

Timer (<leader>ls for stats) — tracks solve time per problem with live display, logs everything to CSV.

Stats (:LeetStats) — floating chart with solve time trends, difficulty breakdown, and moving average.

Both hook into kawre/leetcode.nvim automatically.

Platforms / branches

Branch	Platform	GUI modifier
main	macOS	Cmd (<D->)
windows	Windows	Ctrl (<C->)

The branches are identical except for the VS Code-style shortcuts: macOS uses Cmd, and the windows branch remaps the same chords to Ctrl (via lua/util/modifier.lua). Everything else is shared. In the tables below, the Mac column applies to main and the Windows column applies to the windows branch. Leader is Space.

Keybindings

VS Code-style shortcuts

Action	Mac	Windows
Undo	Cmd+Z	Ctrl+Z
Redo	Cmd+Shift+Z	Ctrl+Shift+Z
Find files	Cmd+P	Ctrl+P
Command palette	Cmd+Shift+P	Ctrl+Shift+P
Search in project (grep)	Cmd+Shift+F	Ctrl+Shift+F
Close tab/buffer	Cmd+W	Ctrl+W
New tab/file	Cmd+T	Ctrl+T
Next tab	Cmd+Shift+]	Ctrl+Shift+]
Previous tab	Cmd+Shift+[	Ctrl+Shift+[
Go to tab 1–9	Cmd+1…Cmd+9	Ctrl+1…Ctrl+9
Toggle file tree	Cmd+B	Ctrl+B

Neovide only: paste Cmd+V / Ctrl+V, zoom in Cmd+= / Ctrl+=, zoom out Cmd+- / Ctrl+-.

Motions & windows (same on both)

Key	Action
;	Enter command mode (:)
jk	Escape (insert mode)
Esc	Clear search highlight
s / S	Flash jump
Shift+H / Shift+L	Previous / next buffer
Ctrl+H/J/K/L	Move between windows
Alt+J / Alt+K	Move line down / up (normal, insert, visual)
< / > (visual)	Indent, keep selection

Leader — find & files

Key	Action
<leader>ff	Find files
<leader>fg	Live grep
<leader>fb	Buffers
<leader>fh	Help tags
<leader>ft	Todos (Telescope)
<leader>e	Toggle file explorer
<leader>n	New file
<leader>c	Close buffer
<leader>q	Quit window
<leader>a	Dashboard

Leader — terminal, LSP & diagnostics

Key	Action
<leader>th / <leader>tv	Terminal (bottom / side split)
q (in run pane)	Close terminal/run pane
gd / gD	Go to definition / declaration
gr / gi	References / implementation
K	Hover docs
<leader>rn	Rename symbol
<leader>ca	Code action
<leader>d	Line diagnostics (float)
<leader>xx / <leader>xb	Diagnostics list / buffer diagnostics (Trouble)
<leader>ll	Run linter
<leader>ls	LeetCode stats

Leader — sessions & todo

Key	Action
<leader>qs	Restore session
<leader>ql	Restore last session
<leader>qd	Stop session recording
<leader>td	Open todo list (floating todo.md)
<leader>tw	Toggle the corner todo widget
<CR> (in todo)	Toggle checkbox
o (in todo)	New checklist item
q (in todo)	Close todo

Competitive programming

C/C++ and Python buffers get extra buffer-local mappings. In c/cpp buffers the CompetiTest mappings shadow the global <leader>a / <leader>e.

Key	Action	Filetypes
F5	Compile & run current file	cpp, python
Cmd+R / Ctrl+R	Compile & run (Neovide only)	cpp, python
<leader>r	CompetiTest: run testcases	c, cpp
<leader>a	CompetiTest: add testcase	c, cpp
<leader>e	CompetiTest: edit testcase	c, cpp

Also driven by commands: :CompetiTest receive problem, :CompetiTest receive contest, :CompetiTest run. C++ compiles with g++ -std=c++20 (-Wall -Wextra -fsanitize=address,undefined under CompetiTest); template at ~/cp/templates/template.cpp.

Setup

# macOS
git clone https://github.com/tms-h/nvim ~/.config/nvim

# Windows (PowerShell)
git clone -b windows https://github.com/tms-h/nvim $env:LOCALAPPDATA\nvim

Open nvim and lazy.nvim installs everything on first launch. Needs Neovim >= 0.10. Optionally works with Neovide (custom cursor, padding, 120Hz configured).
