+# Pure
+
+> Pretty, minimal and fast ZSH prompt
+
+![](screenshot.png)
+
+
+## Overview
+
+Most prompts are cluttered, ugly and slow. I wanted something visually pleasing that stayed out of my way.
+
+### Why?
+
+- Comes with the perfect prompt character.  
+  Author went through the whole Unicode range to find it.
+- Shows `git` branch and whether it's dirty (with a `*`).
+- Indicates when you have unpushed/unpulled `git` commits with up/down arrows.
+- Prompt character turns red if the last command didn't exit with `0`.
+- Command execution time will be displayed if it exceeds the set threshold.
+- Username and host only displayed when in an SSH session.
+- Shows the current path in the title and the [current folder & command](screenshot-title-cmd.png) when a process is running.
+- Makes an excellent starting point for your own custom prompt.
+
+
+## Install
+
+Can be installed with `npm` or manually. Requires git 2.0.0+ and ZSH 5.0.0+.
+
+### npm
+
+```
+$ npm install --global pure-prompt
+```
+
+That's it. Skip to [Getting started](#getting-started).
+
+### Manually
+
+1. Either…
+  - Clone this repo
+  - add it as a submodule, or
+  - just download `pure.zsh`
+
+2. Symlink `pure.zsh` to somewhere in [`$fpath`](http://www.refining-linux.org/archives/46/ZSH-Gem-12-Autoloading-functions/) with the name `prompt_pure_setup`.
+
+3. Symlink `async.zsh` in `$fpath` with the name `async`.
+
+#### Example
+
+```
+$ ln -s "$PWD/pure.zsh" /usr/local/share/zsh/site-functions/prompt_pure_setup
+$ ln -s "$PWD/async.zsh" /usr/local/share/zsh/site-functions/async
+```
+*Run `echo $fpath` to see possible locations.*
+
+For a user-specific installation (which would not require escalated privileges), simply add a directory to `$fpath` for that user:
+
+```sh
+# .zshenv or .zshrc
+fpath=( "$HOME/.zfunctions" $fpath )
+```
+
+Then install the theme there:
+
+```sh
+$ ln -s "$PWD/pure.zsh" "$HOME/.zfunctions/prompt_pure_setup"
+$ ln -s "$PWD/async.zsh" "$HOME/.zfunctions/async"
+```
+
+
+## Getting started
+
+Initialize the prompt system (if not so already) and choose `pure`:
+
+```sh
+# .zshrc
+autoload -U promptinit && promptinit
+prompt pure
+```
+
+
+## Options
+
+### `PURE_CMD_MAX_EXEC_TIME`
+
+The max execution time of a process before its run time is shown when it exits. Defaults to `5` seconds.
+
+### `PURE_GIT_PULL`
+
+Set `PURE_GIT_PULL=0` to prevent Pure from checking whether the current Git remote has been updated.
+
+### `PURE_GIT_UNTRACKED_DIRTY`
+
+Set `PURE_GIT_UNTRACKED_DIRTY=0` to not include untracked files in dirtiness check. Only really useful on extremely huge repos like the WebKit repo.
+
+### `PURE_GIT_DELAY_DIRTY_CHECK`
+
+Time in seconds to delay git dirty checking for large repositories (git status takes > 2 seconds). The check is performed asynchronously, this is to save CPU. Defaults to `1800` seconds.
+
+### `PURE_PROMPT_SYMBOL`
+
+Defines the prompt symbol. The default value is `❯`.
+
+### `PURE_GIT_DOWN_ARROW`
+
+Defines the git down arrow symbol. The default value is `⇣`.
+
+### `PURE_GIT_UP_ARROW`
+
+Defines the git up arrow symbol. The default value is `⇡`.
+
+## Example
+
+```sh
+# .zshrc
+
+autoload -U promptinit && promptinit
+
+# optionally define some options
+PURE_CMD_MAX_EXEC_TIME=10
+
+prompt pure
+```
+
+
+## Tips
+
+[Tomorrow Night Eighties](https://github.com/chriskempson/tomorrow-theme) theme with the [Droid Sans Mono](http://www.google.com/webfonts/specimen/Droid+Sans+Mono) font (15pt) is a beautiful combination, as seen in the screenshot above. Just make sure you have anti-aliasing enabled in your Terminal.
+
+To have commands colorized as seen in the screenshot install [zsh-syntax-highlighting](https://github.com/zsh-users/zsh-syntax-highlighting).
+
+
+## Integration
+
+### [oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh)
+
+1. Remove competing theme included in oh-my-zsh `~/.oh-my-zsh/themes/pure.zsh-theme`
+2. Symlink (or copy) `pure.zsh` to `~/.oh-my-zsh/custom/pure.zsh-theme`
+3. Symlink (or copy) `async.zsh` to `~/.oh-my-zsh/custom/async.zsh`
+4. Add `ZSH_THEME="pure"` to your `.zshrc` file.
+
+### [prezto](https://github.com/sorin-ionescu/prezto)
+
+Set `zstyle ':prezto:module:prompt' theme 'pure'` in `~/.zpreztorc`.
+
+### [antigen](https://github.com/zsh-users/antigen)
+
+Update your `.zshrc` file with the following two lines (order matters). Do not use the `antigen theme` function.
+
+```
+antigen bundle mafredri/zsh-async
+antigen bundle sindresorhus/pure
+```
+
+## FAQ
+
+### My preprompt is missing when I clear the screen with Ctrl+L
+
+Pure doesn't register its custom *clear-screen* widget if it has been previously modified. If you haven't registered your own zle widget with `zle -N clear-screen custom-clear-screen` it might have been done by third-party modules. For example `zsh-syntax-highlighting` and `zsh-history-substring-search` are known to do this and they should for that reason be **the very last thing** in your `.zshrc` (as pointed out in their documentation).
+
+To find out the culprit that is overriding your *clear-screen* widget, you can run the following command: `zle -l | grep clear-screen`.
+
+### I am stuck in a shell loop in my terminal that ask me to authenticate. What should I do ?
+
+[This is a known issue](https://github.com/sindresorhus/pure/issues/76).
+Using `git pull` when you get the username prompt should help you to break the loop by giving you a real prompt for this. **[This has been fixed in git 2.3](https://github.com/sindresorhus/pure/commit/f43ab97e1cf4a276b7a6e33eac055ee16610be15)**
+
+### I am seeing the error `zpty: can't open pseudo terminal: bad file descriptor`.
+
+[This is a known issue](https://github.com/sindresorhus/pure/issues/117). `zsh/zpty` requires either legacy bsd ptys or access to `/dev/ptmx`. Here are some known solutions.
+
+#### Gentoo
+
+```
+sudo sh -c "echo 'SANDBOX_WRITE=\"/dev/ptmx\"' > /etc/sandbox.d/10zsh"
+sudo emerge -1 zsh
+```
+
+#### FreeBSD 10.1
+
+On a default setup, running the command `kldload pty` should do the trick. If you have a custom kernel, you might need to add `device pty` to the configuration file ([example](https://github.com/nbari/freebsd/blob/58646a9c3c4aaabf6f6467ff505f27f09e29dc75/kernels/xen.kernel#L188)).
