Awesome
Pure
Pretty, minimal and fast ZSH prompt
This is a fork of sindresorhus/pure, which aims towards:
- more advanced and fully async git integration (even the branch name resolution does not slow your shell down), and
- Solarized-friendly colors --- for machines and people!
Overview
Most prompts are cluttered, ugly and slow. I wanted something visually pleasing that stayed out of my way.
Why?
- Comes with the traditional
#
and$
as the prompt characters. - Shows
git
branch, whether it has modified/staged/untracked files and upstream status with arrows. All checks are asynchronous. - 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 are colored depending on UID and presence of the SSH session.
- Shows the current path in the title and the current command when a process is running.
- Makes an excellent starting point for your own custom prompt.
Install
Requires Git 2.0.0+ and ZSH 5.2+. Older versions of ZSH are known to work, but they are not recommended.
-
I don't care. Install it with whatever tools you want. No hipster-style
npm --global
installation or other bullshit included. -
Symlink
pure.zsh
to somewhere in$fpath
with the nameprompt_pure_setup
. -
Symlink
async.zsh
in$fpath
with the nameasync
.
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 $fpath
for that user:
# .zshenv or .zshrc
fpath=( "$HOME/.zfunctions" $fpath )
Then install the theme there:
$ 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
:
# .zshrc
autoload -U promptinit; promptinit
prompt pure
Options
Option | Explanation | Default |
---|---|---|
PURE_CMD_MAX_EXEC_TIME | max execution time of a process before it is shown | 5 seconds |
PURE_GIT_FETCH | automatic git fetch , done only once per repo | 1 |
PURE_GIT_FETCH_RETRY | timeout between git fetch retries if failed | 10 seconds |
PURE_GIT_UNTRACKED | enables untracked files in worktree check (disable for speedup) | 1 |
PURE_GIT_DELAY_WORKTREE_CHECK | timeout between git worktree checks, when they take > 2 seconds | 60 |
PURE_GIT_DELAY_UPSTREAM_CHECK | timeout between git upstream checks, when they take > 2 seconds | 60 |
PURE_PROMPT_SYMBOL | the command prompt symbol | # or $ |
PURE_GIT_DOWN_ARROW | git info symbol: branch behind its upstream | ⇣ |
PURE_GIT_UP_ARROW | git info symbol: branch ahead of its upstream | ⇡ |
PURE_GIT_EVEN_ARROW | git info symbol: branch is even with its upstream | empty string |
PURE_GIT_FETCH_IN_PROGRESS | git info string: async fetch in progress | (fetch...) |
PURE_GIT_FETCH_FAILED | git info string: async fetch failed, will retry | (fetch!) |
PURE_GIT_UPSTREAM_NA | git info string: async upstream check in progress | ?u |
PURE_GIT_WORKTREE_NA | git info string: async worktree check in progress | ?w |
PURE_DEBUG | debug output in systemd journal (journalctl -t zshpure ) | 0 |
PURE_ALWAYS_SHOW_USER | show user@host always, not only when connected through SSH | 0 |
The worktree/upstream checks are throttled when the last check takes > 2 seconds. This is to save CPU time.
Custom handlers
There is a global array prompt_pure_pieces
comprised of functions generating
pieces of the preprompt. To add a custom entry to the preprompt, declare a function
generating custom text and insert its name as an entry into the prompt_pure_pieces
array.
The custom function must return generated text by appending new entries to the
preprompt
array (declared in a parent scope) See below for an example.
Example
# .zshrc
autoload -U promptinit; promptinit
# optionally define some options
PURE_CMD_MAX_EXEC_TIME=10
# optionally define custom generators
prompt_custom() {
preprompt+=( custom )
}
prompt pure
# add the generator where it's needed
prompt_pure_pieces=(
${prompt_pure_pieces:0:2}
prompt_custom
${prompt_pure_pieces:2}
)
Tips
To have commands colorized as seen in the screenshot, install zsh-syntax-highlighting.
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.
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
I am seeing the error zpty: can't open pseudo terminal: bad file descriptor
.
This is a known issue. 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).
