In the past week, besides fully indulging myself in the food scene and outdoor activities of the SF Bay Area, I started building a few new personal automation and developer tooling projects. This post shares two of them: asciilint checks that your text files contain only the characters you want, and playwright-byob lets Playwright drive the Chrome you already have installed. https://nanx.me/blog/post/ggsci-5-0-0/ Sun, 19 Apr 2026 01:33:00 +0000 https://nanx.me/blog/post/ggsci-5-0-0/ San Francisco 1.4. Photo by Pine Watt. After the last major version update in September 2025, I am happy to announce the release of ggsci 5.0.0 and ggsci for Python 2.0.0. You can install the R package ggsci from CRAN: install.packages("ggsci") And install the Python package from PyPI: pip install ggsci What’s new Every color palette in ggsci until now has been a fixed list: someone chose those exact colors, arranged them in a particular order, and you used them as-is. https://nanx.me/blog/post/pytest-r-snapshot/ Fri, 02 Jan 2026 03:32:00 +0000 https://nanx.me/blog/post/pytest-r-snapshot/ An earthy, minimalist display blending textured art with dried and fresh botanicals.

You can install it from PyPI: pip install pytest-r-snapshot If your project uses uv, add it as a development dependency: uv add --dev pytest-r-snapshot Why snapshot testing against R? https://nanx.me/blog/post/ggsci-4-0-0/ Thu, 25 Sep 2025 23:36:00 +0000 https://nanx.me/blog/post/ggsci-4-0-0/ Cozy autumn vibes: a warm drink, a good book, and colorful leaves.

You can install the R package ggsci from CRAN: install.packages("ggsci") And install the Python package from PyPI: pip install ggsci This update brings over 400 new discrete color palettes for ggplot2 and plotnine visualizations. https://nanx.me/blog/post/ggsci-python/ Mon, 15 Sep 2025 02:05:00 +0000 https://nanx.me/blog/post/ggsci-python/ Cliff Walk at Pourville (1882) by Claude Monet: two women on a grassy cliff above the sea under a bright sky.

I’m thrilled to announce the release of py-ggsci, a Python package that brings the popular ggsci color palettes from R’s ggplot2 ecosystem to Python’s plotnine library. You can install py-ggsci from PyPI: pip install ggsci Here is a quick example using the Observable 10 palette introduced in ggsci 3. https://nanx.me/blog/post/rtflite-python/ Thu, 13 Feb 2025 00:06:00 +0000 https://nanx.me/blog/post/rtflite-python/ Touring in the clouds.

It is my pleasure to introduce rtflite, a new Python package for generating RTF documents. A preview version is now available on PyPI. You can install it with: pip install rtflite The ultimate goal of rtflite is to provide a lightweight solution for generating production-ready tables, listings, and figures (TLFs) in RTF format. https://nanx.me/blog/post/pkglite-python/ Thu, 16 Jan 2025 02:11:00 +0000 https://nanx.me/blog/post/pkglite-python/ Les Menuires, France. Photo by Yann Allegre. I am pleased to introduce pkglite for Python, now available on PyPI. pkglite for Python provides a minimalist framework for packing source packages written in any programming language into a text file and restoring them to their original directory structure. You can install it with: pip install pkglite For installation as a global command-line tool, use pipx: pipx install pkglite Context Four years ago, we released the R package pkglite, designed for bidirectional conversion of R packages. https://nanx.me/blog/post/tinyvdiff/ Wed, 04 Dec 2024 21:53:00 +0000 https://nanx.me/blog/post/tinyvdiff/ Hummingbirds. Photo by Zdeněk Macháček. I’m delighted to announce my second Python package, tinyvdiff, now available on PyPI. It offers a lightweight pytest plugin for detecting appearance changes in visual content, such as figures or documents. You can install it with: pip install tinyvdiff Setup and usage Here is an example test for matplotlib graphics, from the tinyvdiff demo project: import pytest from tinyvdiff_demo.matplotlib import generate_plot @pytest.fixture def temp_pdf(tmp_path): """Fixture to create a temporary PDF file path""" return tmp_path / "test. https://nanx.me/blog/post/tinytopics/ Sat, 26 Oct 2024 20:42:00 +0000 https://nanx.me/blog/post/tinytopics/ Downhill mountain biking.

You can install it using pip install tinytopics tinytopics is a minimalist solution designed to scale up topic modeling tasks on CPUs and GPUs using PyTorch. Motivation Fitting topic models at scale using classical algorithms on CPUs can be slow. Carbonetto et al. (2022) demonstrated the equivalence between Poisson non-negative matrix factorization (NMF) and multinomial topic model likelihoods.
