Go Bullet Train (GBT)
=====================
Highly configurable prompt builder for Bash, ZSH and PowerShell written in Go.
It's inspired by the [Oh My ZSH](https://github.com/robbyrussell/oh-my-zsh)
[Bullet Train](https://github.com/caiogondim/bullet-train.zsh) theme but runs
significantly faster.
GBT comes with an interesting feature called
[prompt forwarding](#prompt-forwarding) which allows to forward user-defined
prompt to a remote machine and have the same-looking prompt across all machines
via SSH but also in Docker, Kubectl, Vagrant, MySQL or in Screen without the
need to install anything remotely.
All the above works well on Linux (Terminator, Konsole, Gnome Terminal), Mac
(Terminal, iTerm), Android (Termux) and Windows (PowerShell, Windows Terminal).

Setup
-----
In order to setup GBT on your machine, you have to [install](#installation) it,
[activate](#activation) it and setup a special [font](#fonts-and-colors) in your
terminal (optional).
### Installation
#### Arch Linux
```shell
yaourt -S gbt
```
Or install `gbt-git` if you would like to run the latest greatest from the
`master` branch.
#### CentOS/RHEL
Packages hosted by [Packagecloud](https://packagecloud.io/gbt/release):
```shell
echo '[gbt]
name=GBT YUM repo
baseurl=https://packagecloud.io/gbt/release/el/7/$basearch
gpgkey=https://packagecloud.io/gbt/release/gpgkey
https://packagecloud.io/gbt/release/gpgkey/gbt-release-4C6E79EFF45439B6.pub.gpg
gpgcheck=1
repo_gpgcheck=1' | sudo tee /etc/yum.repos.d/gbt.repo >/dev/null
sudo yum install gbt
```
Use the exact repository definition from above for all RedHat-based
distribution regardless its version.
#### Ubuntu/Debian
Packages hosted by [Packagecloud](https://packagecloud.io/gbt/release):
```shell
curl -L https://packagecloud.io/gbt/release/gpgkey | sudo apt-key add -
echo 'deb https://packagecloud.io/gbt/release/ubuntu/ xenial main' | sudo tee /etc/apt/sources.list.d/gbt.list >/dev/null
sudo apt-get update
sudo apt-get install gbt
```
Use the exact repository definition from above for all Debian-based
distribution regardless its version.
#### Mac
Using [`brew`](https://brew.sh):
```shell
brew tap jtyr/repo
brew install gbt
```
Or install `gbt-git` if you would like to run the latest greatest from the
`master` branch:
```shell
brew tap jtyr/repo
brew install --HEAD gbt-git
```
#### Windows
Using [`choco`](https://chocolatey.org):
```powershell
choco install gbt
```
Using [`scoop`](https://scoop.sh):
```powershell
scoop install gbt
```
Or manually by copying the `gbt.exe` file into a directory listed in the `PATH`
environment variable (e.g. `C:\Windows\system32`).
#### Android
Install [Termux](https://termux.com) from [Google Play Store](https://play.google.com/store/apps/details?id=com.termux)
and then type this in the Termux app:
```shell
apt update
apt install gbt
```
#### From the source code
Make sure [Go](https://golang.org) is installed and then run the following on
Linux and Mac:
```shell
mkdir ~/go
export GOPATH=~/go
export PATH="$PATH:$GOPATH/bin"
go get github.com/jtyr/gbt/cmd/gbt
```
Or the following on Windows using PowerShell:
```powershell
mkdir ~/go
$Env:GOPATH = '~/go'
$Env:PATH = "~/go/bin;$Env:PATH"
go install github.com/jtyr/gbt/cmd/gbt@latest
```
---
### Activation
After GBT is installed, it can be activated by calling it from the shell prompt
variable:
```shell
# For Bash
PS1='$(gbt $?)'
# For ZSH
PROMPT='$(gbt $?)'
```
If you are using ZSH together with some shell framework (e.g. [Oh My
ZSH](https://github.com/robbyrussell/oh-my-zsh)), your shell is processing a
fair amount of shell scripts upon ever prompt appearance. You can speed up your
shell by removing the framework dependency from your configuration and replacing
it with GBT and a [simple ZSH
configuration](https://gist.github.com/jtyr/be0e6007bd22c9d51e8702a70430d116#file-zshrc-L1-L43).
Combining pure ZSH configuration with GBT will provide the best possible
performance for your shell.
To activate GBT in PowerShell, run the following in the console or store it to
the PowerShell profile file (`echo $profile`):
```powershell
function prompt {
$rc = [int]$(-Not $?)
$Env:GBT_SHELL = 'plain'
$Env:PWD = get-location
$Env:GBT_CAR_CUSTOM_EXECUTOR='powershell.exe'
$Env:GBT_CAR_CUSTOM_EXECUTOR_PARAM='-Command'
$gbt_output = & @({gbt $rc},{gbt.exe $rc})[$PSVersionTable.PSVersion.Major -lt 6 -or $IsWindows] | Out-String
$gbt_output = $gbt_output -replace ([Environment]::NewLine + '$'), ''
Write-Host -NoNewline $gbt_output
return [char]0
}
# Needed only on Windows
[console]::InputEncoding = [console]::OutputEncoding = New-Object System.Text.UTF8Encoding
```
---
### Fonts and colors
Although GBT can be configured to use only ASCII characters (see
[`basic`](blob/master/themes/basic.sh) theme), the default configuration uses
some UTF-8 characters which require special font. In order to display all
characters of the default prompt correctly, the shell should support UTF-8 and
[Nerd](https://github.com/ryanoasis/nerd-fonts) fonts (or at least the
[DejaVuSansMono
Nerd](https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/DejaVuSansMono/Regular/complete)
font) should be installed. On Linux, you can install it like this:
```shell
mkdir ~/.fonts
curl -L -o ~/.fonts/DejaVuSansMonoNerdFontCompleteMono.ttf https://github.com/ryanoasis/nerd-fonts/raw/master/patched-fonts/DejaVuSansMono/Regular/complete/DejaVu%20Sans%20Mono%20Nerd%20Font%20Complete%20Mono.ttf
fc-cache
```
On Mac, it can be installed via `brew`:
```shell
brew tap homebrew/cask-fonts
brew install --cask font-dejavu-sans-mono-nerd-font
```
On Windows, it can be installed via `choco`:
```powershell
choco install font-nerd-DejaVuSansMono
```
Or via `scoop`:
```powershell
scoop bucket add nerd-fonts
scoop install DejaVuSansMono-NF
```
Or just [download](https://github.com/ryanoasis/nerd-fonts/raw/master/patched-fonts/DejaVuSansMono/Regular/complete/DejaVu%20Sans%20Mono%20Nerd%20Font%20Complete%20Mono%20Windows%20Compatible.ttf)
the font, open it and then install it.
Once the font is installed, it has to be set in the terminal application to
render all prompt characters correctly. Search for the font name `DejaVuSansMono
Nerd Font Mono` on Linux and Mac and `DejaVuSansMono NF` on Windows.
In order to have the Nerd font in Termux on Android, you have to install
[Termux:Styling](https://play.google.com/store/apps/details?id=com.termux.styling)
application. Then longpress the terminal screen and select `MORE...` → `Style`
→ `CHOOSE FONT` and there choose the `DejaVu` font.
Some Unix terminals might not use 256 color palette by default. In such case try
to set the following:
```shell
export TERM='xterm-256color'
```
Configuration
-------------
The prompt (train) is assembled from several elements (cars). The look and
behavior of whole train as well as each car can be influenced by a set of
environment variables. To set the environment variable, use `export` in the
Linux and Mac shell and `$Env:` on Windows.
### Colors
The value of all `_BG` and `_FG` variables defines the background and
foreground color of the particular element. The value of the color can be
specified in 3 ways:
#### Color name
Only a limited number of named colors is supported:
-  `black`
-  `red`
-  `green`
-  `yellow`
-  `blue`
-  `magenta`
-  `cyan`
-  `light_gray`
-  `dark_gray`
-  `light_red`
-  `light_green`
-  `light_yellow`
-  `light_blue`
-  `light_magenta`
-  `light_cyan`
-  `white`
- `default` (default color of the terminal)
Examples:
```shell
# Set the background color of the `Dir` car to red
export GBT_CAR_DIR_BG='red'
# Set the foreground color of the `Dir` car to white
export GBT_CAR_DIR_FG='white'
```
#### Color number
Color can also by expressed by a single number in the range from `0` to
`255`. The color of each number in that range is visible in the 256-color
lookup table on
[Wikipedia](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit). The named
colors described above are the first 16 numbers from the lookup table.
Examples:
```shell
# Set the background color of the `Dir` car to red
export GBT_CAR_DIR_BG='1'
# Set the foreground color of the `Dir` car to white
export GBT_CAR_DIR_FG='15'
```
#### RGB color
Arbitrary color can be expressed in the form of RGB triplet.
Examples:
```shell
# Set the background color of the `Dir` car to red
export GBT_CAR_DIR_BG='170;0;0'
# Set the foreground color of the `Dir` car to white
export GBT_CAR_DIR_FG='255;255;255'
```
#### Color scheme resistance
GBT is using [8-bit color
palette](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) to color
individual cars of the train. First 16 colors (Standart and High-intensity
colors) of the palette are prone to a change if the terminal is using some color
scheme (e.g.
[Solarized](https://en.wikipedia.org/wiki/Solarized_(color_scheme))). That means
that if one GBT train uses mixture of the first 16 and the remaining 240 colors,
the look might be inconsistent because some of the colors might change
(depending on the color scheme) and some not. Luckily the first 16 colors can be
found in the remaining 240 colors and therefore GBT can automatically convert
the first 16 colors into higher colors which provides consistent look regardless
the color scheme. This works automatically for [color names](#color-name) as
well as for [color numbers](#color-number). If needed, the automatic conversion
can be disabled with the following variable:
```shell
export GBT_FORCE_HIGHER_COLORS='0'
```
### Formatting
Formatting is done via `_FM` variables. The possible values are:
- `normal`
Makes the text normal.
- `dim`
Makes the text dim.
- `bold`
Makes the text bold. Not all font characters have variant for bold formatting.
- `underline`
Makes the text underlined.
- `blink`
Makes the text to blink.
- `invert`
Makes the text color inverted.
- `hide`
Makes the text hidden.
- `none`
No formatting applied.
Multiple formattings can be combined into comma-separated list.
Examples:
```shell
# Set the directory name to be bold
export GBT_CAR_DIR_FM='bold'
# Set the directory name to be bold and underlined
export GBT_CAR_DIR_FM='bold,underline'
```
### Train variables
- `GBT_CARS='Status, Os, Hostname, Dir, Git, Sign'`
List of cars used in the train.
To add a new car into the train, the whole variable must be redefined. For
example in order to add the `Time` car into the default set of cars between
the `Os` and `Hostname` car, the variable should look like this:
```shell
export GBT_CARS='Status, Os, Time, Hostname, Dir, Git, Sign'
```
- `GBT_RCARS='Time'`
The same like `GBT_CARS` but for the right hand side prompt.
```shell
# Add the Custom car into the right hand site car to have the separator visible
export GBT_RCARS='Custom, Time'
# Make the Custom car to be invisible (zero length text)
export GBT_CAR_CUSTOM_BG='default'
export GBT_CAR_CUSTOM_FORMAT=''
# Show only time
export GBT_CAR_TIME_FORMAT=' {{ Time }} '
# Set the right hand side prompt (ZSH only)
RPROMPT='$(gbt -right)'
```
- `GBT_SEPARATOR=''`
Character used to separate cars in the train.
- `GBT_RSEPARATOR=''`
The same like `GBT_SEPARATOR` but for the right hand side prompt.
- `GBT_CAR_BG`
Background color inherited by the top background color variable of every car.
That allows to set the background color of all cars via single variable.
- `GBT_CAR_FG`
Foreground color inherited by the top foreground color variable of every car.
That allows to set the foreground color of all cars via single variable.
- `GBT_CAR_FM`
Formatting inherited by the top formatting variable of every car. That allows
to set the formatting of all cars via single variable.
- `GBT_BEGINNING_BG='default'`
Background color of the text shown at the beginning of the train.
- `GBT_BEGINNING_FG='default'`
Foreground color of the text shown at the beginning of the train.
- `GBT_BEGINNING_FM='none'`
Formatting of the text shown at the beginning of the train.
- `GBT_BEGINNING_TEXT=''`
Text shown at the beginning of the train.
- `GBT_SHELL`
Indicates which shell is used. The value can be either `zsh`, `bash` or
`plain`. By default, the value is extracted from the `$SHELL` environment
variable. Set this variable to `bash` if your default shell is ZSH but you
want to test GBT in Bash:
```shell
export GBT_SHELL='bash'
bash
```
If set to `plain`, no shell-specific decoration is included in the output
text. That's suitable for displaying the GBT-generated string in the console
output.
- `GBT_DEBUG='0'`
Shows more verbose output if some of the car modules cannot be imported.

Benchmark
---------
Benchmark of GBT can be done by faking the output of GBT by a testing script
which executes as minimum of commands as possible. For simplicity, the test will
produce output of the Git car only and will be done from within a directory with
a Git repository.
The testing script is using exactly the same commands like GBT to determine the
Git branch, whether the Git repository contains any change and whether it's
ahead/behind of the remote branch. The script has the following content and is
stored in `/tmp/test.sh`:
```shell
BRANCH="$(git symbolic-ref HEAD)"
[ -z "$(git status --porcelain)" ] && DIRTY_ICON='%{\e[38;5;2m%}✔' || DIRTY_ICON='%{\e[38;5;1m%}✘'
[[ "$(git rev-list --count HEAD..@{upstream})" == '0' ]] && AHEAD_ICON='' || AHEAD_ICON=' ⬆'
[[ "$(git rev-list --count @{upstream}..HEAD)" == '0' ]] && BEHIND_ICON='' || BEHIND_ICON=' ⬇'
echo -en "%{\e[0m%}%{\e[48;5;7m%}%{\e[38;5;0m%} %{\e[48;5;7m%}%{\e[38;5;0m%}%{\e[48;5;7m%}%{\e[38;5;0m%} %{\e[48;5;7m%}%{\e[38;5;0m%}${BRANCH##*/}%{\e[48;5;7m%}%{\e[38;5;0m%} %{\e[48;5;7m%}%{\e[38;5;0m%}%{\e[48;5;7m%}$DIRTY_ICON%{\e[48;5;7m%}%{\e[38;5;0m%}%{\e[48;5;7m%}%{\e[38;5;0m%}%{\e[48;5;7m%}%{\e[38;5;0m%}$AHEAD_ICON%{\e[48;5;7m%}%{\e[38;5;0m%}%{\e[48;5;7m%}%{\e[38;5;0m%}$BEHIND_ICON%{\e[48;5;7m%}%{\e[38;5;0m%} %{\e[0m%}"
```
The testing script produces the same output like GBT when run by Bash or ZSH:
```shell
bash /tmp/test.sh > /tmp/a
zsh /tmp/test.sh > /tmp/b
GBT_SHELL='zsh' GBT_CARS='Git' gbt > /tmp/c
diff /tmp/{a,b}
diff /tmp/{b,c}
```
We will use ZSH to run 10 measurements of 100 executions of the testing script
by Bash and ZSH as well as of GBT itself.
```shell
# Execution of the testing script by Bash

From the above is visible that GBT performs faster than Bash and ZSH even if the
testing script was as simple as possible. You can also notice that GBT was using
more CPU than Bash or ZSH. That's probably because of the built-in concurrency
support in Go.
Prompt forwarding
-----------------
In order to enjoy GBT prompt via SSH but also in Docker, Kubectl, Vagrant, MySQL
or in Screen without the need to install GBT everywhere, you can use GBTS (GBT
written in Shell). GBTS is a set of scripts which get forwarded to applications
and remote connections and then executed to generate the nice looking prompt.
You can start using it by doing the following:
```shell
export GBT__HOME='/usr/share/gbt'
source $GBT__HOME/sources/gbts/cmd/local.sh
```
This will automatically create command line aliases for all enabled plugins (by
default `docker`, `gssh`, `kubectl`, `mysql`, `screen`, `ssh`, `su`, `sudo` and
`vagrant`). Then just SSH to some remote server or enter some Docker container
(even via `kubectl`) or Vagrant box and you should get GBT prompt there.
If you want to have some of the default aliase available only on the remote
site, just un-alias them locally:
```shell
unalias sudo su
```
You can also forward your own aliases which will be then available on any remote
site. For example to have `alias ll='ls -l'` on any remote site, just create the
following alias and it will be automatically forwarded:
```shell
alias gbt___ll='ls -l'
```
The idea behind prompt forwarding is coming from Vladimir Babichev
(@[mrdrup](https://github.com/mrdrup)) who was using it for several years
before GBT even existed. After seeing the potential of GBT, he sparked the
implementation of prompt forwarding into GBT which later turned into GBTS.
### Principle
Principle of GBTS is to pass the GBTS scripts to the application and then execute
them. This is done by concatting all the GBTS scripts into one file and encoding
it by Base64 algorithm. Such string, together with few more commands, is then
used as an argument of the application which makes it to store it on the remote
site in the `/tmp/.gbt.` file. The same we create the `/tmp/.gbt..bash`
script which is then used as a replacement of the real shell on the remote site.
For SSH it would look like this:
```shell
ssh -t myserver "export GBT__CONF='$GBT__CONF' && echo '' | base64 -d > \$GBT__CONF && bash --rcfile \$GBT__CONF"
```
In order to make all this invisible, we wrap that command into a function (e.g.
`gbt_ssh`) and assign it to an `alias` of the same name like the original
application (e.g. `ssh`):
```shell
alias ssh='gbt_ssh'
```
The same or very similar principle applies to other supported commands like
`docker`, `gssh` ([GCP
SSH](https://cloud.google.com/sdk/gcloud/reference/compute/ssh)), `kubectl`,
`mysql`, `screen`, `su`, `sudo` and `vagrant`.
### Additional settings
GBTS has few settings which can be used to influence its behaviour. See the
details [here](https://github.com/jtyr/gbt/tree/master/sources/gbts/README.md).
### MacOS users
To make GBTS working correctly between Linux and MacOS and vice versa requires a
little bit of fiddling. The reason is that the basic command line tools like
`date` and `base64` are very old on MacOS and mostly incompatible with the Linux
world. Some tools are even called differently (e.g. `md5sum` is called `md5`).
Therefore if you want to make the remote script verification working (make sure
nobody changed the remote script while using it), the following variables must be
set:
```shell
# Use 'md5' command instead of 'md5sum'
export GBT__SOURCE_MD5_LOCAL='md5'
# Cut the 4th field from the output of 'md5'
export GBT__SOURCE_MD5_CUT_LOCAL='4'
```
If you don't want to use this feature, you can disable it in which case the above
variables won't be required:
```shell
export GBT__SOURCE_SEC_DISABLE=1
```
When using the `ExecTime` car, the following variable must be set:
```shell
# Don't use nanoseconds in the 'ExecTime' car
export GBT__SOURCE_DATE_ARG='+%s'
```
For maximum compatibility with GBT, it's recommended to install GNU `coreutils`
(`brew install coreutils`) and instead of the variable above use these:
```shell
# Use 'gdate' instead of 'date'
export GBT__SOURCE_DATE='gdate'
# Use 'gdate' instead of 'date' (only if you run GBT on a Mac)
export GBT__SOURCE_BASE64_LOCAL='gbase64'
# Use 'gdate' instead of 'date' (only if you are connection to Mac via SSH)
export GBT__SOURCE_BASE64='gbase64'
```
When connecting to MacOS from Linux using `gbt_ssh` and not using `gbase64` on
MacOS, the following variable must be set on Linux to make the Base64 decoding
working on MacOS:
```shell
# Use 'base64 -D' to decode Base64 encoded text
export GBT__SOURCE_BASE64_DEC='-D'
```
### Limitations
- Requires Bash v4.x to run.
- The [color representation](https://bugs.mysql.com/79755) and [support of
unicode characters](https://bugs.mysql.com/89359) for MySQL is broken in MySQL
5.6 and above. But it works just fine in all versions of Percona and MariaDB.
- Plugins `su` and `sudo` are not supported on MacOS.
TODO
----
Contribution to the following is more than welcome:
- Optimize generated escape sequence
- Don't decorate empty string
- Don't decorate child element with the same attributes used by the parent
- Implement templating language to allow more dynamic configuration
- Jinja2-like syntax
- Should be able to refer variables from the local car
- `GBT_CAR_GIT_BG="{% 'red' if Status == '{{ StatusDirty }}' else 'light_gray' %}"`
- Should be able to refer ENV variables (e.g. `env('HOME')`)
- Could be able to refer variables from another car
- Advanced functionality via pipes (e.g. ` | substr(1,3)`)
- Add support for GBT [plugins](https://golang.org/pkg/plugin/)
- Load plugins with `GBT_PLUGINS='mycar1:/path/to/mycar1.so;mycar2:/path/to/mycar2.so'`
- Load the plugin, read the `Car` symbol and assign the reference to the
`mycar1` in the `carsFactory`
- Implement Vim statusline using GBT as the generator
- Implement Tmux statusline using GBT as the generator
- Add weather car
- Using Yahoo Weather API
- Needs to cache the results in a file and refresh only if its timestamp is
older than certain time. Or perhaps store the last update in env var?
- Add more themes
