Intro

did you ever heared of Jetporch, short Jet ? Don’t worry, you’re not the only one ;) Jet Project of Jet is being led by Michael DeHaan, the original creator of Ansible. So, expect something like Ansible, faster, written in rust … same same, but different.

Installation on Debian 12

grab a fresh machine and patch it

export DEBIAN_FRONTEND=noninteractive
apt-get clean
apt-get autoclean
apt-get update -y
apt-get upgrade -yq
apt-get dist-upgrade -yq
apt-get autoremove -y

Install Rust from Source

jet needs rustc 1.64. Debian install 1.63 from packages :(

Let’s play with Packages and Libraries

References

Switch to Root Folder

cd /some/path/you/want

Create a new Package

poetry new mypackage

add some libraries

poetry add requests

… add some code …

cat << 'EOF' > mypackage/__init__.py
print("importing", __name__)
EOF

cat << 'EOF' > mypackage/main.py
print("importing", __name__)

def test1():
  print("test1")

def test2(name: str):
  print("hello", name)

def test3(name: str, age:int):
  print(f"Hello {name} at age {age}")

if __name__ == "__main__":
  print("This is a Library or Package. You should import it into your Code and not run it directly ...")
EOF

Build Package

poetry build

List Tree

(mypackage-py3.11) stoege@host:~/git/demo/mypackage> tree

you have a package called “mypackage-0.1.0” created. As ’tar.gz and ‘.whl’ File

How to add a Table to Hugo

Create Table Shortcode

cat <<'EOF'> layouts/shortcodes/table.html    
{{ $htmlTable := .Inner | markdownify }} {{ $class := .Get 0 }} {{ $old := "<table>" }}
{{ $new := printf "<table class=\"%s\">" $class }} {{ $htmlTable :=
  replace $htmlTable $old $new }} {{ $htmlTable | safeHTML }}
</table>
EOF

Build Table

add this to your Markdown File …

| a | b | c |
| - | - | - |
| bli | bla | blu |
| green | blue | red |

Result

a	b	c
bli	bla	blu
green	blue	red

Align Left

| a | b | c |
| :- | :- | :- |
| bli | bla | blu |
| green | blue | red |

Result

a	b	c
bli	bla	blu
green	blue	red

Align Right

| a | b | c |
| -: | -: | -: |
| bli | bla | blu |
| green | blue | red |

Result

The certificate issuer is unknown.  Could not handshake: Error in the certificate verification. [IP: xx.xx.xx.xx yyyy]

Disable TLS Check

touch /etc/apt/apt.conf.d/99verify-peer.conf

Storing Data in JSON - TinyDB

Small Example how to Store Data in JSON, and Query them afterwards like a NOSQL DB. Have a look at TinyDB if you wanna see more.

Code

from tinydb import TinyDB, Query
from pprint import pprint

# Create or load a database file
db = TinyDB('db.json')

# insert some sample data
def insert():
    # Insert data
    db.insert({'name': 'John', 'age': 30})
    db.insert({'name': 'Alice', 'age': 25, 'hobbies': 'sleep'})
    db.insert({'name': 'Max', 'age': 20, 'hobbies': ['sleep', 'play', 'eat']})

# show all entries
def show_all():
    all_records = db.all()
    pprint(all_records)

# entries with hobbies
def show_entries_with_hobbies():
    User = Query()
    result = db.search(User.hobbies.exists())
    pprint(result)

# entries without hobbies
def show_entries_without_hobbies():
    User = Query()
    result = db.search(~User.hobbies.exists())
    pprint(result)

# show entries with hobbies and older than 22 years
def show_entries_with_hobbies_and_older_than_22():
    User = Query()
    result =  db.search((User.hobbies.exists()) & (User.age > 22))
    pprint(result)

if __name__ == "__main__":
  # Add
  insert()

  # show
  print("\n-- ALL --")
  show_all()

  print("\n-- with Hobbies --")
  show_entries_with_hobbies()

  print("\n-- without Hobbies --")
  show_entries_without_hobbies()


  print("\n-- with Hobbies and older than 22 --")
  show_entries_with_hobbies_and_older_than_22()

Run

you need to install tinydb. use a virtual env like .venv, poetry or whatever you like
