Just released ryl v0.22: the fast Rust YAML linter! Its language server no longer burns CPU on an idle workspace: workspace diagnostics are long-polled, and large repos stream results as they are linted. Thanks to Olav for the report. ryl-docs.pages.dev #rust #yaml #linter

Just released ryl 0.19.1, the fast Rust YAML linter. New: winget install on Windows, plus config in a .config/ dir (.config/ryl.toml). Homebrew tap for Mac/Linux next? Homebrew wants 225 stars to self-submit; ryl's at 43. A star helps. github.com/owenlamont/ryl #rust #yaml #linter

Just released ryl v0.12 + v0.13: the fast Rust YAML linter now requires explicit rule opt-in, hardens against malicious YAML payloads, and adds a tags rule flagging unsafe/non-portable tags like !!python/object See github.com/owenlamont/r... #rust #yaml #linter

Release v0.11.0 · owenlamont/ryl

⚠️ Breaking changes (0.10.2 → 0.11.0) This release is not purely additive. Before upgrading: TOML yaml-files is rejected — use [files].yaml instead. A ryl.toml / .ryl.toml / [tool.ryl] that sets y...

I just released aiomoto 0.5.0 - my async wrapper / replacement for moto to PyPi. This release drops aioboto3 support which appears stale but unblocks later versions of aiobotocore. Given AWS has feature frozen the boto3 resource APIs anyway, I recommend moving to aiobotocore. #Python #AWS #Testing

I just released github.com/owenlamont/ryl v0.10.0, now with: read YAML from stdin via ryl - (with optional --stdin-filename, ruff-style). Safe --fix now covers trailing-spaces, document-start, document-end, and empty-lines. Thanks github.com/eread for the stdin suggestion. #rust #yaml #linter

I just released ryl 0.9.2 which cleans up some package bloat / bugs and adds @zensical.org docs which are much easier on the eyes. Documentation approach shamelessly copied from rumdl. The documentation is viewable here: ryl-docs.pages.dev #rust #yaml #linter

I just released aiomoto 0.4.0 - my async wrapper / replacement for moto - this release drops support for Python 3.10 but adds support for the latest moto, pandas, and polars versions. Thanks to github.com/tylerriccio33 and github.com/jtjeferreira for the contributions! #Python #AWS #Testing

I just released ryl 0.9.0 with automatic fix support for quoted strings. I hope to keep adding more automatic fixes as I go. Thanks to github.com/o-l-a-v for the suggested improvement. See github.com/owenlamont/ryl for install options. #rust #yaml #linter

ryl v0.8.0 is out with these features: - Per-file rule ignores - JSON Schema for ryl.toml (available via SchemaStore) - quote-type consistent mode, and single quotes permits double-quoted strings for escape sequences Thanks github.com/o-l-a-v and github.com/gecube for suggesting #rust #yaml #linter

uv now has an audit command for checking your dependencies for vulnerabilities so I archived my uv-secure package which was a work-around before audit existed. Thanks to everyone that took the time to raise issues for uv-secure. Please check the README for alternative tools. #python #devsecops

I just released ryl 0.6.0 to crates/pypi/npm with new automatic fixes for spacing around: - braces - brackets - commas - comments-indentation Also fixed a bug with top level list elements (thanks for raising github.com/frague59 ) #rust #yaml #linter

I just released ryl 0.5.0 - I originally aimed for feature parity with yamllint but I'm now trying to follow ruff and rumdl and start implementing automatic fixes (where obvious) and hopefully auto formatting eventually. More to come soon. #yaml #linter #rust

After several false starts ryl 0.4.4 is now available on npm. I'd never published an npm package before and had no idea how much harder it is to publish an executable CLI wrapper there compared to PyPi, but it's finally up. Thanks to @biomejs.dev and esbuild for the inspiration. #yaml #linter

I just released ryl 0.4.0 to crates.io and PyPi. This version adds support for toml configuration files (including pyproject.toml files). It also adds migrate functions to convert your old yaml configuration files to toml. yaml config is still supported though of course. #python #rust #yaml

I just released ryl 0.3.5 to PyPi and Crates.io - (now tested against several larger repos that were heavy yamllint users) and resolved several bugs and behaviour discrepancies with yamllint. #python #rust #yaml

I just released uv-secure 0.17.0 to PyPi - this version has a couple of improvements: 1. Better color highlighting for dependencies failing maintenance constraints 2. A new --fix option and toml config to auto fix unnecessary package/vulnerability ignores. #python #cybersecurity #devsecops

Just resurrected an old side project. This is ryl 0.3.4, a rewrite of yamllint in Rust released on PyPi. It aims to be a drop in replacement for yamllint, parsing and discovering files the same. It's not been used in anger and I'm a Rust newbie but please try it and raise bugs! #python #rust
