pyg will be a PEG parser library formed as an internal Python DSL. it will be used in cramex, a copycat of cram with expect support.

The surface is heading to resemble Boost.Spirit: grammars are composed using a vaguely (xBNF/PEG)-like syntax enabled through operator overloading.

>>> from pyg import Rule, chr_, int_

>>> n = Rule('number')
>>> o = Rule('operator')
>>> e = Rule('expression')

>>> e %= n >> o >> n
>>> o %= chr_('+-')
>>> n %= int_

>>> e.matches('42 + 69')
True, None
>>> e.matches('69')
True, None
>>> e.matches('42 69')
False, "Failed on line 1 column 3:\n42 69\n  ^\n"

    Improvements to osc (especially with regards to the Git workflow) by mcepl

    Description

    There is plenty of hacking on osc, where we could spent some fun time. I would like to see a solution for https://github.com/openSUSE/osc/issues/2006 (which is sufficiently non-serious, that it could be part of HackWeek project).


    Enhance git-sha-verify: A tool to checkout validated git hashes by gpathak

    Description

    git-sha-verify is a simple shell utility to verify and checkout trusted git commits signed using GPG key. This tool helps ensure that only authorized or validated commit hashes are checked out from a git repository, supporting better code integrity and security within the workflow.

    Supports:

    • Verifying commit authenticity signed using gpg key
    • Checking out trusted commits

    Ideal for teams and projects where the integrity of git history is crucial.

    Goals

    A minimal python code of the shell script exists as a pull request.

    The goal of this hackweek is to:

    • DONE: Add more unit tests
      • New and more tests can be added later
    • Partially DONE: Make the python code modular
    • DONE: Add code coverage if possible

    Collection and organisation of information about Bulgarian schools by iivanov

    Description

    To achieve this it will be necessary:

    • Collect/download raw data from various government and non-governmental organizations
    • Clean up raw data and organise it in some kind database.
    • Create tool to make queries easy.
    • Or perhaps dump all data into AI and ask questions in natural language.

    Goals

    By selecting particular school information like this will be provided:

    • School scores on national exams.
    • School scores from the external evaluations exams.
    • School town, municipality and region.
    • Employment rate in a town or municipality.
    • Average health of the population in the region.

    Resources

    Some of these are available only in bulgarian.

    • https://ri.mon.bg/active-institutions
    • https://www.nsi.bg/nrnm/ekatte/archive

    Results

    • Information about all Bulgarian schools with their scores during recent years cleaned and organised into SQL tables
    • Information about all Bulgarian villages, cities, municipalities and districts cleaned and organised into SQL tables
    • Information about all Bulgarian villages and cities census since beginning of this century cleaned and organised into SQL tables.
    • Information about all Bulgarian municipalities about religion, ethnicity cleaned and organised into SQL tables.
    • Data successfully loaded to locally running Ollama with help to Vanna.AI
    • Seems to be usable.

    TODO

    • Add more statistical information about municipalities and ....

    Song Search with CLAP by gcolangiuli

    Description

    Contrastive Language-Audio Pretraining (CLAP) is an open-source library that enables the training of a neural network on both Audio and Text descriptions, making it possible to search for Audio using a Text input. Several pre-trained models for song search are already available on huggingface

    SUSE Hackweek AI Song Search

    Goals

    Evaluate how CLAP can be used for song searching and determine which types of queries yield the best results by developing a Minimum Viable Product (MVP) in Python. Based on the results of this MVP, future steps could include:

    • Music Tagging;
    • Free text search;
    • Integration with an LLM (for example, with MCP or the OpenAI API) for music suggestions based on your own library.

    The code for this project will be entirely written using AI to better explore and demonstrate AI capabilities.

    Result

    In this MVP we implemented:

    • Async Song Analysis with Clap model
    • Free Text Search of the songs
    • Similar song search based on vector representation
    • Containerised version with web interface

    We also documented what went well and what can be improved in the use of AI.

    You can have a look at the result here:

    Future implementation can be related to performance improvement and stability of the analysis.

    Improve chore and screen time doc generator script `wochenplaner` by gniebler

    Description

    I wrote a little Python script to generate PDF docs, which can be used to track daily chore completion and screen time usage for several people, with one page per person/week.

    I named this script wochenplaner and have been using it for a few months now.

    It needs some improvements and adjustments in how the screen time should be tracked and how chores are displayed.

    Goals

    • Fix chore field separation lines
    • Change screen time tracking logic from "global" (week-long) to daily subtraction and weekly addition of remainders (more intuitive than current "weekly time budget method)
    • Add logic to fill in chore fields/lines, ideally with pictures, falling back to text.
