Simple command-line snippet manager, written in Go

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

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.

pet has the following features.

• Register your command snippets easily.
• Use variables 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.

Some examples are shown below.

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

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

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

See below for details.

By adding the following config to .bashrc, you can search snippets and output on the shell.

$ 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'

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

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

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

You can share snippets via Gist.

To experience pet in action, try it out in this free O'Reilly Katacoda scenario, Pet, a CLI Snippet Manager. As an example, you'll see how pet may enhance your productivity with the Kubernetes kubectl tool. Explore how you can use pet to curated a library of helpful snippets from the 800+ command variations with kubectl.

[[snippets]]
  command = "echo | openssl s_client -connect example.com:443 2>/dev/null |openssl x509 -dates -noout"
  description = "Show expiration date of SSL certificate"
  output = """

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
------------------------------

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)

[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

Example1: Change layout (bottom up)

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

Example2: Enable colorized output

$ pet configure
[General]
...
  selectcmd = "fzf --ansi"
...
$ pet search --color

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

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

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..

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

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

You need to install selector command (fzf or peco).
homebrew install fzf automatically.

Go to the releases page, find the version you want, and download the zip file. Unpack the zip file, and put the binary to somewhere you want (on UNIX-y systems, /usr/local/bin or the like). Make sure it has execution bits turned on.

You can use homebrew on OS X.

$ brew install knqyf263/pet/pet

If you receive an error (Error: knqyf263/pet/pet 64 already installed) during brew upgrade, try the following command

$ brew unlink pet && brew uninstall pet
($ rm -rf /usr/local/Cellar/pet/64)
$ brew install knqyf263/pet/pet

Download rpm package from the releases page

$ sudo rpm -ivh https://github.com/knqyf263/pet/releases/download/v0.3.0/pet_0.3.0_linux_amd64.rpm

$ wget https://github.com/knqyf263/pet/releases/download/v0.3.6/pet_0.3.6_linux_amd64.deb
dpkg -i pet_0.3.6_linux_amd64.deb

Two packages are available in AUR. You can install the package from source:

$ yaourt -S pet-git

Or from the binary:

$ yaourt -S pet-bin

$ mkdir -p $GOPATH/src/github.com/knqyf263
