Algorithm-DataStructures

Implementations of common algorithms and data structures used for competitive programming.

Vim plugin

The algorithms and data structures can easily be pasted into a document using the included Vim plugin.

Installation

Use vim-plug or any Vim plugin manager of your choice. The plugin fzf is a requirement.

With vim-plug:

Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
Plug 'jakobkogler/Algorithm-DataStructures'

Command/Usage

The plugin defines a single command AlgDS. It can be mapped like this:

nmap <leader>alg :AlgDS<CR>

Pretty Printer

There are some pretty printer for GDB. You can activate them by putting the following in your ~/.gdbinit:

source ~/.vim/plugged/Algorithm-DataStructures/prettyprint.py

WTFPL

Make your Vim/Neovim as smart as VSCode.

True snippet and additional text editing support

Why?

🚀 Fast: instant increment completion, increment buffer sync using buffer update events.
💎 Reliable: typed language, tested with CI.
🌟 Featured: full LSP support
❤️ Flexible: configured like VSCode, extensions work like in VSCode

Quick Start

Install nodejs >= 10.12:

curl -sL install-node.now.sh/lts | bash

For vim-plug users:

" Use release branch (recommend)
Plug 'neoclide/coc.nvim', {'branch': 'release'}

" Or build from source code by using yarn: https://yarnpkg.com
Plug 'neoclide/coc.nvim', {'branch': 'master', 'do': 'yarn install --frozen-lockfile'}

in your .vimrc or init.vim, then restart Vim and run :PlugInstall.

Checkout Install coc.nvim for more info.

You have to install coc extension or configure language servers for LSP support.

Install extensions like:

:CocInstall coc-json coc-tsserver

Or configure language server in coc-settings.json opened by :CocConfig, like:

{
  "languageserver": {
    "go": {
      "command": "gopls",
      "rootPatterns": ["go.mod"],
      "trace.server": "verbose",
      "filetypes": ["go"]
    }
  }
}

Checkout wiki for more details:

Checkout :h coc-nvim for vim interface.

Example vim configuration

Configuration is required to make coc.nvim easier to work with, since it doesn't change your key-mappings or Vim options. This is done as much as possible to avoid conflict with your other plugins.

❗️Important: Some Vim plugins could change key mappings. Please use :verbose imap <tab> to make sure that your keymap has taken effect.

" Set internal encoding of vim, not needed on neovim, since coc.nvim using some
" unicode characters in the file autoload/float.vim

Fantasque Sans Mono

A programming font, designed with functionality in mind, and with some wibbly-wobbly handwriting-like fuzziness that makes it unassumingly cool. Download or see installation instructions.

Previously known as Cosmic Sans Neue Mono. It appeared that similar names were already in use for other fonts, and that people tended to extend their instinctive hatred of Comic Sans to this very font of mine (which of course can only be loved). Why the previous name? Here is my original explanation:

The name comes from my realization that at some point it looked like the mutant child of Comic Sans and Helvetica Neue. Hopefully it is not the case any more.

Inspirational sources include Inconsolata and Monaco. I have also been using Consolas a lot in my programming life, so it may have some points in common.

Weights, variants and glyph coverage

The font includes a bold version, with the same metrics as the regular one. Both versions include the same ranges of characters : latin letters, some accented glyphs (quite a lot), some greek letters, some arrows.

Please note that I have not tested all of the glyphs I have drawn (some letters have those two layers of crazy accents that I have never witnessed before), so it might look bad in some cases. Please report these problems: see next section.

It also features a good italic version, which I designed in a fashion similar to Consolas' italic version, with new glyph designs, not just an added slant.

Stylistic set(s)

`ss01`: nondescript `k`

No ~~distractive~~ lovely loop. Get the pre-activated version here or see the issue #67 for techniques to activate the stylistic set.

Please send me an e-mail or report an issue on Github if you stumble upon bad design or rendering problems (with screen shot if possible), or if you need more characters, or if you want to compliment me (I love compliments).

Installation

You can download the latest version and install it by hand. In the NoLoopK variant, the looped lowercase k is replaced with a straight version. The LargeLineHeight variant is especially useful for users of accented capitals. For more info, see the CHANGELOG.

Automatic installation on macOS with homebrew:

brew tap homebrew/cask-fonts #You only need to do this once for cask-fonts
brew install --cask font-fantasque-sans-mono

Instructions for other platforms might follow.

Building installable font files

The build process requires:

FontForge with python scripting support,
ttfautohint
sfnt2woff (from the woff-tools package on Ubuntu)
woff2_compress from the Google WOFF2 tools or woff2 package on Ubuntu

Run make. You should see green stuff and some "OK" messages.

If you are using Ubuntu, please note that the FontForge version in the default Ubuntu repositories is much outdated at the time of this writing, and that is known to have caused subtle problems. You are advised to install FontForge from this PPA (using sudo add-apt-repository ppa:fontforge/fontforge prior to the installation). Alternatively, you can always download the latest prebuilt release of these fonts.

make install will install the TTF fonts into your local .fonts/ directory and update the font cache. It comes in handy while modifying the font.

Alternatively, if you'd like to build Fantasque without installing required dependencies, a Dockerfile is provided. Run the following command, and the fonts will be built to the ./Variants directory.

docker build -t fantasque .
docker run -v "$(pwd)/Variants:/fantasque/Variants" fantasque

Webfonts

Each variant has a Webfonts/ folder which contains various font formats for use on the web, along with the matching CSS font declarations. To use them, you must combine in the same folder:

a custom .css file that you can assemble from the *-decl.css fragments (you can only pick the styles that you need, e.g. normal and bold)
the matching .svg, .woff, .woff2 files from Webfonts/
the matching .ttf files from the TTF/ folder
the matching .otf files from the OTF/ folder.

Versions

Check out the changelog.

The NERDTree

Introduction

The NERDTree is a file system explorer for the Vim editor. Using this plugin, users can visually browse complex directory hierarchies, quickly open files for reading or editing, and perform basic file system operations.

Installation

Use your favorite plugin manager to install this plugin. tpope/vim-pathogen, VundleVim/Vundle.vim, junegunn/vim-plug, and Shougo/dein.vim are some of the more popular ones. A lengthy discussion of these and other managers can be found on vi.stackexchange.com. Basic instructions are provided below, but please be sure to read, understand, and follow all the safety rules that come with your ~~power tools~~ plugin manager.

If you have no favorite, or want to manage your plugins without 3rd-party dependencies, consider using Vim 8+ packages, as described in Greg Hurrell's excellent Youtube video: Vim screencast #75: Plugin managers.

Pathogen

Pathogen is more of a runtime path manager than a plugin manager. You must clone the plugins' repositories yourself to a specific location, and Pathogen makes sure they are available in Vim.

In the terminal,

git clone https://github.com/preservim/nerdtree.git ~/.vim/bundle/nerdtree

In your vimrc,

call pathogen#infect()
syntax on
filetype plugin indent on

Restart Vim, and run :helptags ~/.vim/bundle/nerdtree/doc/ or :Helptags.

Vundle

Install Vundle, according to its instructions.

Add the following text to your vimrc.

call vundle#begin()
  Plugin 'preservim/nerdtree'
call vundle#end()

Restart Vim, and run the :PluginInstall statement to install your plugins.

Vim-Plug

Install Vim-Plug, according to its instructions.
Add the following text to your vimrc.

call plug#begin()
  Plug 'preservim/nerdtree'
call plug#end()

Restart Vim, and run the :PlugInstall statement to install your plugins.

Dein

Install Dein, according to its instructions.

Add the following text to your vimrc.

call dein#begin()
  call dein#add('preservim/nerdtree')
call dein#end()

Restart Vim, and run the :call dein#install() statement to install your plugins.

Vim 8+ packages

If you are using Vim version 8 or higher you can use its built-in package management; see :help packages for more information. Just run these commands in your terminal:

git clone https://github.com/preservim/nerdtree.git ~/.vim/pack/vendor/start/nerdtree
vim -u NONE -c "helptags ~/.vim/pack/vendor/start/nerdtree/doc" -c q

Getting Started

After installing NERDTree, the best way to learn it is to turn on the Quick Help. Open NERDTree with the :NERDTree command, and press ? to turn on the Quick Help, which will show you all the mappings and commands available in the NERDTree. Of course, your most complete source of information is the documentation: :help NERDTree.

NERDTree Plugins

NERDTree can be extended with custom mappings and functions using its built-in API. The details of this API and are described in the included documentation. Several plugins have been written, and are available on Github for installation like any other plugin. The plugins in this list are maintained (or not) by their respective owners, and certain combinations may be incompatible.

Xuyuanp/nerdtree-git-plugin: Shows Git status flags for files and folders in NERDTree.
ryanoasis/vim-devicons: Adds filetype-specific icons to NERDTree files and folders,
tiagofumo/vim-nerdtree-syntax-highlight: Adds syntax highlighting to NERDTree based on filetype.
scrooloose/nerdtree-project-plugin: Saves and restores the state of the NERDTree between sessions.
PhilRunninger/nerdtree-buffer-ops: 1) Highlights open files in a different color. 2) Closes a buffer directly from NERDTree.
PhilRunninger/nerdtree-visual-selection: Enables NERDTree to open, delete, move, or copy multiple Visually-selected files at once.

If any others should be listed, mention them in an issue or pull request.

Frequently Asked Questions

In the answers to these questions, you will see code blocks that you can put in your vimrc file.

How can I map a specific key or shortcut to open NERDTree?

NERDTree doesn't create any shortcuts outside of the NERDTree window, so as not to overwrite any of your other shortcuts. Use the nnoremap command in your vimrc. You, of course, have many keys and NERDTree commands to choose from. Here are but a few examples.

nnoremap <leader>n :NERDTreeFocus<CR>
nnoremap <C-n> :NERDTree<CR>
nnoremap <C-t> :NERDTreeToggle<CR>
nnoremap <C-f> :NERDTreeFind<CR>

How do I open NERDTree automatically when Vim starts?

Each code block below is slightly different, as described in the " Comment lines.

" Start NERDTree and leave the cursor in it.
autocmd VimEnter * NERDTree

" Start NERDTree and put the cursor back in the other window.
autocmd VimEnter * NERDTree | wincmd p

" Start NERDTree when Vim is started without file arguments.
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 0 && !exists('s:std_in') | NERDTree | endif

" Start NERDTree. If a file is specified, move the cursor to its window.
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * NERDTree | if argc() > 0 || exists("s:std_in") | wincmd p | endif

" Start NERDTree, unless a file or session is specified, eg. vim -S session_file.vim.
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 0 && !exists('s:std_in') && v:this_session == '' | NERDTree | endif

" Start NERDTree when Vim starts with a directory argument.
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists('s:std_in') |
    \ execute 'NERDTree' argv()[0] | wincmd p | enew | execute 'cd '.argv()[0] | endif

How can I close Vim automatically when NERDTree is the last window?

" Exit Vim if NERDTree is the only window left.
autocmd BufEnter * if tabpagenr('$') == 1 && winnr('$') == 1 && exists('b:NERDTree') && b:NERDTree.isTabTree() |
    \ quit | endif

How can I prevent other buffers replacing NERDTree in its window?

" If another buffer tries to replace NERDTree, put it in the other window, and bring back NERDTree.
autocmd BufEnter * if bufname('#') =~ 'NERD_tree_\d\+' && bufname('%') !~ 'NERD_tree_\d\+' && winnr('$') > 1 |
    \ let buf=bufnr() | buffer# | execute "normal! \<C-W>w" | execute 'buffer'.buf | endif

Can I have the same NERDTree on every tab automatically?

" Open the existing NERDTree on each new tab.
autocmd BufWinEnter * silent NERDTreeMirror

or change your NERDTree-launching shortcut key like so:

" Mirror the NERDTree before showing it. This makes it the same on all tabs.
nnoremap <C-n> :NERDTreeMirror<CR>:NERDTreeFocus<CR>

How can I change the default arrows?

let g:NERDTreeDirArrowExpandable = '▸'
let g:NERDTreeDirArrowCollapsible = '▾'

The preceding values are the non-Windows default arrow symbols. Setting these variables to empty strings will remove the arrows completely and shift the entire tree two character positions to the left. See :h NERDTreeDirArrowExpandable for more details.

vim-airline

Lean & mean status/tabline for vim that's light as air.

When the plugin is correctly loaded, there will be a nice statusline at the bottom of each vim window.

That line consists of several sections, each one displaying some piece of information. By default (without configuration) this line will look like this:

+-----------------------------------------------------------------------------+
|~                                                                            |
|~                                                                            |
|~                     VIM - Vi IMproved                                      |

|~                                                                            |
|~           type :h :q<Enter>          to exit                               |
|~           type :help<Enter> or <F1>  for on-line help                      |
|~           type :help version8<Enter> for version info                      |
|~                                                                            |
|~                                                                            |
+-----------------------------------------------------------------------------+
| A | B |                     C                            X | Y | Z |  [...] |
+-----------------------------------------------------------------------------+

The statusline is the colored line at the bottom, which contains the sections (possibly in different colors):

section	meaning (example)
A	displays the mode + additional flags like crypt/spell/paste (INSERT)
B	Environment status (VCS information - branch, hunk summary (master), battery level)
C	filename + read-only flag (~/.vim/vimrc RO)
X	filetype (vim)
Y	file encoding[fileformat] (utf-8[unix])
Z	current position in the file
[...]	additional sections (warning/errors/statistics) from external plugins (e.g. YCM, syntastic, ...)

The information in Section Z looks like this:

10% ☰ 10/100 ln : 20

This means:

10%     - 10 percent down the top of the file
☰ 10    - current line 10
/100 ln - of 100 lines
: 20    - current column 20

For a better look, those sections can be colored differently, depending on various conditions (e.g. the mode or whether the current file is 'modified')

Features

Tiny core written with extensibility in mind (open/closed principle).
Integrates with a variety of plugins, including: vim-bufferline, fugitive, unite, ctrlp, minibufexpl, gundo, undotree, nerdtree, tagbar, vim-gitgutter, vim-signify, quickfixsigns, syntastic, eclim, lawrencium, virtualenv, tmuxline, taboo.vim, ctrlspace, vim-bufmru, vimagit, denite, vim.battery and more.
Looks good with regular fonts and provides configuration points so you can use unicode or powerline symbols.
Optimized for speed - loads in under a millisecond.
Extensive suite of themes for popular color schemes including solarized (dark and light), tomorrow (all variants), base16 (all variants), molokai, jellybeans and others. Note these are now external to this plugin. More details can be found in the themes repository.
Supports 7.2 as the minimum Vim version.
The master branch tries to be as stable as possible, and new features are merged in only after they have gone through a full regression test.
Unit testing suite.

Straightforward customization

If you don't like the defaults, you can replace all sections with standard statusline syntax. Give your statusline that you've built over the years a face lift.

Themes

Themes have moved to another repository as of this commit.

Install the themes as you would this plugin (Vundle example):

Plugin 'vim-airline/vim-airline'
Plugin 'vim-airline/vim-airline-themes'

See vim-airline-themes for more.

Automatic truncation

Sections and parts within sections can be configured to automatically hide when the window size shrinks.

Smarter tab line

Automatically displays all buffers when there's only one tab open.

This is disabled by default; add the following to your vimrc to enable the extension:

let g:airline#extensions#tabline#enabled = 1

Separators can be configured independently for the tabline, so here is how you can define "straight" tabs:

let g:airline#extensions#tabline#left_sep = ' '
let g:airline#extensions#tabline#left_alt_sep = '|'

In addition, you can also choose which path formatter airline uses. This affects how file paths are displayed in each individual tab as well as the current buffer indicator in the upper right. To do so, set the formatter field with:

let g:airline#extensions#tabline#formatter = 'default'

Here is a complete list of formatters with screenshots:

`default`

`jsformatter`

`unique_tail`

vim-airline integrates with a variety of plugins out of the box. These extensions will be lazily loaded if and only if you have the other plugins installed (and of course you can turn them off).

ctrlp.vim

unite.vim

denite.nvim

tagbar

csv.vim

syntastic

hunks (vim-gitgutter & vim-signify & coc-git)

vimagit

virtualenv

tmuxline

promptline

ctrlspace

xkb-switch/xkb-layout

vimtex

localsearch

LanguageClient

Vim-CMake

vim.battery

Extras

vim-airline also supplies some supplementary stand-alone extensions. In addition to the tabline extension mentioned earlier, there is also:

whitespace

statusline on top

The statusline can alternatively be drawn on top, making room for other plugins to use the statusline: The example shows a custom statusline setting, that imitates Vims default statusline, while allowing to call custom functions. Use :let g:airline_statusline_ontop=1 to enable it.

Configurable and extensible

Fine-tuned configuration

Every section is composed of parts, and you can reorder and reconfigure them at will.

Sections can contain accents, which allows for very granular control of visuals (see configuration here).

Extensible pipeline

Completely transform the statusline to your liking. Build out the statusline as you see fit by extracting colors from the current colorscheme's highlight groups.

Rationale

There's already powerline, why yet another statusline?

100% vimscript; no python needed.

What about vim-powerline?

vim-powerline has been deprecated in favor of the newer, unifying powerline, which is under active development; the new version is written in python at the core and exposes various bindings such that it can style statuslines not only in vim, but also tmux, bash, zsh, and others.

Where did the name come from?

I wrote the initial version on an airplane, and since it's light as air it turned out to be a good name. Thanks for flying vim!

Installation

This plugin follows the standard runtime path structure, and as such it can be installed with a variety of plugin managers:

Plugin Manager	Install with...
Pathogen	`git clone https://github.com/vim-airline/vim-airline ~/.vim/bundle/vim-airline` Remember to run `:Helptags` to generate help tags
NeoBundle	`NeoBundle 'vim-airline/vim-airline'`
Vundle	`Plugin 'vim-airline/vim-airline'`
Plug	`Plug 'vim-airline/vim-airline'`
VAM	`call vam#ActivateAddons([ 'vim-airline' ])`
Dein	`call dein#add('vim-airline/vim-airline')`
minpac	`call minpac#add('vim-airline/vim-airline')`
pack feature (native Vim 8 package feature)	`git clone https://github.com/vim-airline/vim-airline ~/.vim/pack/dist/start/vim-airline` Remember to run `:helptags ~/.vim/pack/dist/start/vim-airline/doc` to generate help tags
manual	copy all of the files into your `~/.vim` directory

Documentation

:help airline

Integrating with powerline fonts

For the nice looking powerline symbols to appear, you will need to install a patched font. Instructions can be found in the official powerline documentation. Prepatched fonts can be found in the powerline-fonts repository.

Finally, you can add the convenience variable let g:airline_powerline_fonts = 1 to your vimrc which will automatically populate the g:airline_symbols dictionary with the powerline symbols.

Solutions to common problems can be found in the Wiki.

Performance

Whoa! Everything got slow all of a sudden...

vim-airline strives to make it easy to use out of the box, which means that by default it will look for all compatible plugins that you have installed and enable the relevant extension.

Many optimizations have been made such that the majority of users will not see any performance degradation, but it can still happen. For example, users who routinely open very large files may want to disable the tagbar extension, as it can be very expensive to scan for the name of the current function.

The minivimrc project has some helper mappings to troubleshoot performance related issues.

If you don't want all the bells and whistles enabled by default, you can define a value for g:airline_extensions. When this variable is defined, only the extensions listed will be loaded; an empty array would effectively disable all extensions (e.g. :let g:airline_extensions = []).

Also, you can enable caching of the various syntax highlighting groups. This will try to prevent some of the more expensive :hi calls in Vim, which seem to be expensive in the Vim core at the expense of possibly not being one hundred percent correct all the time (especially if you often change highlighting groups yourself using :hi commands). To set this up do :let g:airline_highlighting_cache = 1. A :AirlineRefresh will however clear the cache.

In addition you might want to check out the dark_minimal theme, which does not change highlighting groups once they are defined. Also please check the FAQ for more information on how to diagnose and fix the problem.

vim.cpp - additional vim c++ syntax highlighting

This file contains additional syntax highlighting that I use for C++11/14/17 development in Vim. Compared to the standard syntax highlighting for C++ it adds highlighting of (user defined) functions and the containers and types in the standard library / boost.

Development is done at: http://github.com/octol/vim-cpp-enhanced-highlight

Optional features

Highlighting of class scope is disabled by default. To enable set

let g:cpp_class_scope_highlight = 1

Highlighting of member variables is disabled by default. To enable set

let g:cpp_member_variable_highlight = 1

Highlighting of class names in declarations is disabled by default. To enable set

let g:cpp_class_decl_highlight = 1

Highlighting of POSIX functions is disabled by default. To enable set

let g:cpp_posix_standard = 1

There are two ways to highlight template functions. Either

let g:cpp_experimental_simple_template_highlight = 1

which works in most cases, but can be a little slow on large files. Alternatively set

let g:cpp_experimental_template_highlight = 1

which is a faster implementation but has some corner cases where it doesn't work.

Note: C++ template syntax is notoriously difficult to parse, so don't expect this feature to be perfect.

Highlighting of library concepts is enabled by

let g:cpp_concepts_highlight = 1

This will highlight the keywords concept and requires as well as all named requirements (like DefaultConstructible) in the standard library.

Highlighting of user defined functions can be disabled by

let g:cpp_no_function_highlight = 1

Installation instructions

Follow one of the sets of directions below and reload vim afterwards.

Vundle

Install using vundle by adding

Plugin 'octol/vim-cpp-enhanced-highlight'

to .vimrc and run :PluginInstall.

Git submodule + Pathogen

If you have pathogen installed, and you prefer to use git submodules, run

cd ~/.vim
git submodule add https://github.com/octol/vim-cpp-enhanced-highlight.git bundle/syntax/

Manual installation

If you don't have either Vundle or Pathogen installed, copy the cpp.vim file (optionally also c.vim) to .vim/after/syntax.

git clone https://github.com/octol/vim-cpp-enhanced-highlight.git /tmp/vim-cpp-enhanced-highlight
mkdir -p ~/.vim/after/syntax/
mv /tmp/vim-cpp-enhanced-highlight/after/syntax/cpp.vim ~/.vim/after/syntax/cpp.vim
rm -rf /tmp/vim-cpp-enhanced-highlight

Issues

Vim tend to a have issues with flagging braces as errors, see for example vim-jp/vim-cpp#16. A workaround is to set

let c_no_curly_error=1
