    SCons

    SCons

    A software construction tool

    SCons is a software construction tool that is a superior alternative to the classic "Make" build tool that we all know and love. SCons is implemented as a Python script and set of modules, and SCons "configuration files" are actually executed as Python scripts. This gives SCons many powerful capabilities not found in other software build tools. We make SCons available in three distinct packages, for different purposes. - The scons package is the basic package to install SCons. You don't need any other package if you just want to try out SCons. - The scons-local package executes as a SCons standalone, out of a local directory. It's intended to be dropped in to and shipped with packages of other software for builds with SCons but not as a required install. - The scons-src package is the complete source tree, including everything we use to package SCons and all of the regression tests.

    Celery

    Celery

    Distributed task queue (development branch)

    Celery is a simple, flexible, and reliable distributed system to process vast amounts of messages, while providing operations with the tools required to maintain such a system. It’s a task queue with focus on real-time processing, while also supporting task scheduling. Celery has a large and diverse community of users and contributors, you should come join us on IRC or our mailing-list. Celery is Open Source and licensed under the BSD License. A task queue’s input is a unit of work called a task. Dedicated worker processes constantly monitor task queues for new work to perform. Celery communicates via messages, usually using a broker to mediate between clients and workers. To initiate a task the client adds a message to the queue, the broker then delivers that message to a worker. A Celery system can consist of multiple workers and brokers, giving way to high availability and horizontal scaling. Celery is written in Python, but the protocol can be implemented in any language.

    Luigi

    Luigi

    Python module that helps you build complex pipelines of batch jobs

    Luigi is a Python (3.6, 3.7, 3.8, 3.9 tested) package that helps you build complex pipelines of batch jobs. It handles dependency resolution, workflow management, visualization, handling failures, command line integration, and much more. The purpose of Luigi is to address all the plumbing typically associated with long-running batch processes. You want to chain many tasks, automate them, and failures will happen. These tasks can be anything, but are typically long running things like Hadoop jobs, dumping data to/from databases, running machine learning algorithms, or anything else. You can build pretty much any task you want, but Luigi also comes with a toolbox of several common task templates that you use. It includes support for running Python mapreduce jobs in Hadoop, as well as Hive, and Pig, jobs. It also comes with file system abstractions for HDFS, and local files that ensures all file system operations are atomic.

    PyInstaller

    PyInstaller

    Converts (packages) Python programs into stand-alone executables

    PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

    PPT Builder Skill

    PPT Builder Skill

    AI-friendly PPT builder skill: 17 hand-polished Chinese PPTX templates

    PPT Builder Skill is an AI-friendly PowerPoint builder skill designed to create editable native PPTX presentations from structured content. It includes polished Chinese presentation templates and uses python-pptx-based tools to preserve layout while applying controlled text edits. The skill supports workflows where an agent selects a template, writes an edits file, and produces a real PowerPoint file with the original design intact. It can also work with user-provided templates by inspecting slide images and shape structures before applying non-destructive changes. For original presentations, it guides agents toward clean layouts with simple typography, generous spacing, and restrained visual elements. The project is intended for personal learning and research use, not commercial use.

    virtualenv

    virtualenv

    Virtual Python environment builder

    virtualenv is a tool to create isolated Python environments. Since Python 3.3, a subset of it has been integrated into the standard library under the venv module. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either). The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these libraries? If you install everything into your host python (e.g. python3.8) it’s easy to end up in a situation where two packages have conflicting requirements.

    Gooey

    Gooey

    Turn Python command line programs into a full GUI application

    Gooey is a tool for transforming command line interfaces into beautiful desktop applications. It can be used as the frontend client for any language or program. Whether you've built your application in Java, Node, or Haskell, or you just want to put a pretty interface on an existing tool like FFMPEG, Gooey can be used to create a fast, practically free UI with just a little bit of Python (about 20 lines!). To show how this all fits together, and that it really works for anything, we're going to walk through building a graphical interface to one of my favorite tools of all time: FFMPEG. These steps apply to anything, though! You could swap out FFMPEG for a .jar you've written, or an arbitrary windows .exe, an OSX .app bundle, or anything on linux that's executable! In short, it will transform a "scary" terminal command line into an easy to use desktop application that you could hand over to users.

    Software Copyright Materials Skill

    Software Copyright Materials Skill

    Skills, a Chinese software copyright application material generator

    Software Copyright Skill is an open-source Codex skill for generating Chinese software copyright application materials from a local software project. It helps developers prepare the documents required for a software copyright filing without relying on paid document-preparation services. The skill reads the real project, guides the user through key confirmations, and produces organized materials that can be reviewed and edited locally. It can generate application-form reference information, an operation manual, and source-code materials in Word and text formats. The project is designed to avoid invented code by extracting only from the user’s existing source files. It is especially useful for developers who want control over sensitive project details while still producing structured, submission-ready drafts.

    Debreate - Debian Package Builder

    Debreate - Debian Package Builder

    A utility for creating Debian packages (.deb)

    Debreate is a utility to aid in creating Debian (.deb) packages. Currently it only supports binary packaging (note that the term "binary package" is used loosely, as such packages can contain scripts & non-code items such as media images, audio, & more) for personal distribution. Plans for using backends such as dh_make & debuild for creating source packages are in the works. But source packaging can be quite different & is a must if you want to get your packages into a distribution's official repositories or a Launchpad Personal Package Archive (PPA). The latter from which Debreate is available.
