# 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)).
