# Pet - CLI Snippet Manager

[![GitHub release](https://img.shields.io/github/release/knqyf263/pet.svg)](https://github.com/knqyf263/pet/releases/latest)

# Motivation

`pet` is a simple command-line snippet manager (inspired by [memo](https://github.com/mattn/memo)).

I have a hard time remembering complex command or ones that I rarely use. Moreover, it is difficult to find them in shell history.

It's time to let go of the expectation of remembering every command, and focus on productivity and finding the right commands as fast as possible. It's fun when you're 2 years in and work with 2 tools, but less so when you're a decade in and work across backend/frontend/infrastructure with tons of tools. You most probably relate to this if you're a developer.

`pet` is a simple tool that allows you to save, tag, search, and execute command-line snippets easily! It's now nearly 8 years old and is used by many developers around the world.

`pet` is written in Go, and therefore you can just grab the binary releases and drop it in your $PATH.

You can use variables (`<param>` or `<param=default_value>` ) in snippets.

# Main features
`pet` has the following features.

- Register your command snippets easily.
- Use variables (with one or several default values) in snippets.
- Search snippets interactively
- Run snippets directly.
- Edit snippets easily (config is just a TOML file).
- Sync snippets via Gist or GitLab Snippets automatically.

# Creating a snippet

You can create a snippet by running `pet new`.

```
$ pet new
Command> echo Hello world!
Description> print Hello world
```

To see all available arguments, run `pet new --help`.

Multiline commands can be entered by using the multiline argument `pet new --multiline`

You can use also use variables in snippets, these are called parameters. More information on that in the next section.

You can also *tag* snippets to search for them faster. More information on that in the tag section.

# Parameters
There are `<n_ways>` ways of entering parameters.

They can contain default values: Hello `<subject=world>`
defined by the equal sign.

They can even contain `<content=spaces & = signs>` where the default value would be \<content=<mark>spaces & = signs</mark>\>.

Default values just can't \<end with spaces \>.

They can also contain multiple default values:
Hello `<subject=|_John_||_Sam_||_Jane Doe = special #chars_|>`

The values in this case would be :Hello \<subject=\|\_<mark>John</mark>\_\|\|\_<mark>Sam</mark>\_\|\|\_<mark>Jane Doe = special #chars</mark>\_\|\>

# Examples
Some examples are shown below.

## Register the previous command easily
By adding the following config to `.bashrc` or `.zshrc`, you can easily register the previous command.

### bash prev function

```
function prev() {
  PREV=$(echo `history | tail -n2 | head -n1` | sed 's/[0-9]* //')
  sh -c "pet new `printf %q "$PREV"`"
}
```

### zsh prev function

```
cat .zshrc
function prev() {
  PREV=$(fc -lrn | head -n 1)
  sh -c "pet new `printf %q "$PREV"`"
}
```

### fish
See below for details.  
https://github.com/otms61/fish-pet

## Select snippets at the current line (like C-r) (RECOMMENDED)

### bash
By adding the following config to `.bashrc`, you can search snippets and output on the shell.
This will also allow you to execute the commands yourself, which will add them to your shell history! This is basically the only way we can manipulate shell history.
This also allows you to *chain* commands! [Example here](https://github.com/knqyf263/pet/discussions/266)

You can also customize the search and list commands with options, example `-t` or `--tags`, for example to only search the subset of snippets tagged with myjob `pet search -t myjob`.

```
cat .bashrc
function pet-select() {
  BUFFER=$(pet search --query "$READLINE_LINE")
  READLINE_LINE=$BUFFER
  READLINE_POINT=${#BUFFER}
}
bind -x '"\C-x\C-r": pet-select'
```

### zsh

```
cat .zshrc
function pet-select() {
  BUFFER=$(pet search --query "$LBUFFER")
  CURSOR=$#BUFFER
  zle redisplay
}
zle -N pet-select
stty -ixon
bindkey '^s' pet-select
```

### fish
See below for details.  
https://github.com/otms61/fish-pet

## Expand snippet parameters inline on shell

You can expand parameters using the shell instead of the builtin TUI dialog. This allows you to edit the parameters with native shell features, like tab-completion, highlighting, etc.

### bash

```bash
function pet-select() {
  BUFFER=$(pet search --raw --query "$READLINE_LINE")
  READLINE_LINE=$BUFFER
  READLINE_POINT=${#BUFFER}
}
bind -x '"\C-x\C-r": pet-select'

function _pet_move_cursor_to_next_parameter() {
  match="$(echo "$READLINE_LINE" | perl -nle 'print $& if /<.*?>/')"
  if [ -n "$match" ]; then
    default="$(echo "$match" | perl -nle 'print $& if /(?<==).*(?=>)/')"
    match_len=${#match}
    default_len=${#default}

pre_match=${READLINE_LINE%%$match*}
    parameter_offset=${#pre_match}

READLINE_POINT="$((${parameter_offset} + ${default_len}))"
    READLINE_LINE="${READLINE_LINE:0:$parameter_offset}${default}${READLINE_LINE:$parameter_offset+$match_len}"
  fi        
}
bind -x '"\C-n": _pet_move_cursor_to_next_parameter'
```

### zsh

```zsh
function pet-select() {
  BUFFER=$(pet search --raw --query "$LBUFFER")
  CURSOR=$#BUFFER
  zle redisplay
}
zle -N pet-select
stty -ixon
bindkey '^s' pet-select

function _pet_move_cursor_to_next_parameter() {
    match="$(echo "$BUFFER" | perl -nle 'print $& if /<.*?>/')"
    if [ -n "$match" ]; then
      default="$(echo "$match" | perl -nle 'print $& if /(?<==).*(?=>)/')"
      match_len=${#match}
      default_len=${#default}
      parameter_offset=${#BUFFER%%$match*}

CURSOR="$((${parameter_offset} + ${default_len}))"
      BUFFER="${BUFFER[1,$parameter_offset]}${default}${BUFFER[$parameter_offset+$match_len+1,-1]}"
    fi        
}
zle -N _pet_move_cursor_to_next_parameter
bindkey '^n' _pet_move_cursor_to_next_parameter 
```

## Copy snippets to clipboard
By using `pbcopy` on macOS, you can copy snippets to clipboard.

## Allow to register from history when using fzf

Just export this to your `.bashrc` or `.zshrc` file. This will show your history
as default (when using fzf) and it also binds the `alt+s` key combination
to allow you to search and save some previous used command command.

```
export FZF_CTRL_R_OPTS="
  --reverse
  --cycle
  --info=right
  --color header:italic
  --header 'alt+s (pet new)'
  --preview 'echo {}' --preview-window down:3:hidden:wrap 
  --bind '?:toggle-preview'
  --bind 'alt-s:execute(pet new --tag {2..})+abort'"
```

  description = "Show expiration date of SSL certificate"
  output = """
notBefore=Nov  3 00:00:00 2015 GMT
notAfter=Nov 28 12:00:00 2018 GMT"""
```

Run `pet list`

```
    Command: echo | openssl s_client -connect example.com:443 2>/dev/null |openssl x509 -dates -noout
Description: Show expiration date of SSL certificate
     Output: notBefore=Nov  3 00:00:00 2015 GMT
             notAfter=Nov 28 12:00:00 2018 GMT
------------------------------
```

# Configuration

Run `pet configure`

```
[General]
  snippetfile = "path/to/snippet" # specify snippet directory
  editor = "vim"                  # your favorite text editor
  column = 40                     # column size for list command
  selectcmd = "fzf"               # selector command for edit command (fzf or peco)
  backend = "gist"                # specify backend service to sync snippets (gist, ghe or gitlab, default: gist)
  sortby  = "description"         # specify how snippets get sorted (recency (default), -recency, description, -description, command, -command, output, -output)
  cmd = ["sh", "-c"]              # specify the command to execute the snippet with
  color = false                   # enables output coloring with fzf, same as '--color' flag
  format = "[$description]: $command $tags" controls the format of the output when searching

[Gist]
  file_name = "pet-snippet.toml"  # specify gist file name
  access_token = ""               # your access token
  gist_id = ""                    # Gist ID
  public = false                  # public or priate
  auto_sync = false               # sync automatically when editing snippets

[GitLab]
  file_name = "pet-snippet.toml"  # specify GitLab Snippets file name
  access_token = "XXXXXXXXXXXXX"  # your access token
  id = ""                         # GitLab Snippets ID
  visibility = "private"          # public or internal or private
  auto_sync = false               # sync automatically when editing snippets
```

## Multi directory and multi file setup

Directories must be specified as an array.
All `toml` files will be scraped and found snippets will be added.

Example1: single directory

```toml
[GHEGist]
  base_url = ""                   # GHE base URL
  upload_url = ""                 # GHE upload URL (often the same as the base URL)
  file_name = "pet-snippet.toml"  # specify gist file name
  access_token = ""               # your access token
  gist_id = ""                    # Gist ID
  public = false                  # public or priate
  auto_sync = false               # sync automatically when editing snippets
```

```
$ pet configure
[General]
...
  snippetdirs = ["/path/to/some/snippets/"]
...
```

Example2: multiple directories

```
$ pet configure
[General]
...
  snippetdirs = ["/path/to/some/snippets/", "/more/snippets/"]
...
```
 If `snippetfile` setting is omitted, new snippets will be added in a separate file to the first directory. The generated filename is time based.

Snippet files in `snippetdirs` will not be added to Gist or GitLab. You've to do version control manually.

## Selector option
Example1: Change layout (bottom up)

```
pet configure
[General]
...
  selectcmd = "fzf"
...
```

Example2: Enable colorized output
```
pet configure
[General]
...
  selectcmd = "fzf --ansi"
...
pet search --color
```

## Tag
You can use tags (delimiter: space).
```
pet new -t
Command> ping 8.8.8.8
Description> ping
Tag> network google
```

Or edit manually.
```
pet edit
[[snippets]]
  description = "ping"
  command = "ping 8.8.8.8"
  tag = ["network", "google"]
  output = ""
```

They are displayed with snippets.
```
pet search
[ping]: ping 8.8.8.8 #network #google
```

You can exec snippet with filtering the tag

```
pet exec -t google

[ping]: ping 8.8.8.8 #network #google
```

## Sync
### Gist
You must obtain access token.
Go https://github.com/settings/tokens/new and create access token (only need "gist" scope).
Set that to `access_token` in `[Gist]` or use an environment variable with the name `$PET_GITHUB_ACCESS_TOKEN`.

After setting, you can upload snippets to Gist.  
If `gist_id` is not set, new gist will be created.
```
pet sync
Gist ID: 1cedddf4e06d1170bf0c5612fb31a758
Upload success
```

Set `Gist ID` to `gist_id` in `[Gist]`.
`pet sync` compares the local file and gist with the update date and automatically download or upload.

If the local file is older than gist, `pet sync` download snippets.
```
pet sync
Download success
```

If gist is older than the local file, `pet sync` upload snippets.
```
pet sync
Upload success
```

*Note: `-u` option is deprecated*

### GHE Gist

To use Gist with GitHub Enterprise, you need to follow these steps:

1. Obtain an Access Token: Visit your GitHub Enterprise settings page to create a new access token with just the "gist" scope. This is necessary to authenticate and interact with the Gist API on GitHub Enterprise.
2. Set the Access Token: Assign the newly created access token to `access_token` in the `[GHEGist]` section of your configuration. Alternatively, you can use an environment variable named `$PET_GITHUB_ENTERPRISE_ACCESS_TOKEN` to manage your token securely.
3. Configure API Endpoints: Unlike the regular Gist config, you need to set `base_url` and `upload_url` to point to your GitHub Enterprise API endpoints. For example:

```toml

[GHEGist]
base_url = "https://github-enterprise.example.com/api/v3/gists"
upload_url = "https://github-enterprise.example.com/api/v3/gists"  # Often the same as the base URL
```

By setting these parameters, your tool will be configured to interact with GitHub Enterprise Gist, enabling you to sync and manage your snippets just as you would with the standard GitHub Gist service.

Remember to replace `https://github-enterprise.example.com` with the actual URL of your GitHub Enterprise instance. This customization allows your tool to correctly connect to and use the Gist service in a GitHub Enterprise environment.

### GitLab Snippets
You must obtain access token.
Go https://gitlab.com/-/profile/personal_access_tokens and create access token.
Set that to `access_token` in `[GitLab]` or use an environment variable with the name `$PET_GITLAB_ACCESS_TOKEN`.

You also have to configure the `url` under `[GitLab]`, so pet knows which endpoint to access. You would use `url = "https://gitlab.com"`unless you have another instance of Gitlab.

At last, switch the `backend` under `[General]` to `backend = "gitlab"`.

After setting, you can upload snippets to GitLab Snippets.
If `id` is not set, new snippet will be created.
```
pet sync
GitLab Snippet ID: 12345678
Upload success
```

Set `GitLab Snippet ID` to `id` in `[GitLab]`.
`pet sync` compares the local file and gitlab with the update date and automatically download or upload.

If the local file is older than gitlab, `pet sync` download snippets.
```
pet sync
Download success
```

If gitlab is older than the local file, `pet sync` upload snippets.
```
pet sync
Upload success
```

## Auto Sync
You can sync snippets automatically.
Set `true` to `auto_sync` in `[Gist]`, `[GHEGist]` or `[GitLab]`.
Then, your snippets sync automatically when `pet new` or `pet edit`.

```
pet edit
Getting Gist...
Updating Gist...
Upload success
```
