pet : CLI Snippet Manager
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.

Main features
pet has the following features.
- Register your command snippets easily.
- Use variables in snippets.
- Search snippets interactively.

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"`"
}

$ 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

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.
Hands-on Tutorial
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.

Snippet
Run pet edit
You can also register the output of command (but cannot search).
[[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 = """
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 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

Upload success
