pet : CLI Snippet Manager

GitHub release MIT License

Simple command-line snippet manager, written in Go

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

Abstract

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

pet is a simple command-line snippet manager (inspired by memo). I always forget commands that I rarely use. Moreover, it is difficult to search them from shell history. There are many similar commands, but they are all different.

e.g.

  • $ awk -F, 'NR <=2 {print $0}; NR >= 5 && NR <= 10 {print $0}' company.csv (What I am looking for)
  • $ awk -F, '$0 !~ "DNS|Protocol" {print $0}' packet.csv
  • $ awk -F, '{print $0} {if((NR-1) % 5 == 0) {print "----------"}}' test.csv

In the above case, I search by awk from shell history, but many commands hit.

Even if I register an alias, I forget the name of alias (because I rarely use that command).

So I made it possible to register snippets with description and search them easily.

TOC

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.

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=spaces & = signs>.

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=|_John_||_Sam_||_Jane Doe = special #chars_|>

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

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

$ 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

Copy snippets to clipboard

By using pbcopy on OS X, you can copy snippets to clipboard.

Features

Edit snippets

The snippets are managed in the TOML file, so it's easy to edit.

Sync snippets

You can share snippets via Gist.

             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 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

[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

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 snipet 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

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] or [GitLab]. Then, your snippets sync automatically when pet new or pet edit.

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