Pyparsing 3.1.0 released
After over a year since the last release of pyparsing, I've bundled up all the bug-fixes and changes, and they are now released as pyparsing 3.1.0. Visit this link for the details.

Need help developing an interpreter
Look into "parser combinators" for building an interpreter. There's a few ones out there, but PyParsing is one I've seen around that looks pretty nifty.

About a month ago I posted about PRegEx, an open-source project which I had started that you can use to build RegEx patterns programmatically, which the subreddit seem to like. This prompted me to keep working on it, and one month later, PRegEx v2.0.0 is out!
I havent found a way to specify an exact character match in pyparsing - https://github.com/pyparsing/pyparsing/discussions/443

Parser Combinators in Haskell
Since it is not mentioned in the article: Python users may also want to check out pyparsing [0]. It is slightly different from Parsec/FParsec (for instance, it ignores all whitespace by default), but I think it is a really good project.

Pyparsing 3.0.x - off to a rocky start, but I think 3.0.6 looks fairly solid
Here is the page of all the new changes and features in pyparsing 3.0.
- luna is a Domain specific language that translates to regex. It's an attempt to make regex more readable.

Recommended way to read and parse a couple thousand small files
Your pyparsing parser might benefit from a tune-up. This page has some performance tips: https://github.com/pyparsing/pyparsing/wiki/Performance-Tips.

Script for extracting info from a SQL File
If your SQL has fairly complex structure, you will need a full blown SQL parser. If your statements are mostly simple select, you can get pretty close with Pyparsing, here is an example.

Rapier is a set of 2D and 3D physics engines written in Rust
Fun fact: I used GA in Excalidraw, and it's still powering some of the interactions! https://github.com/excalidraw/excalidraw/blob/master/package...

Ask HN: Anyone use a code to mindmap/flowchart tool?
I was happy to find out recently that there is a way to make Mermaid diagrams WYSIWYG / drag and drop editable that the open source https://excalidraw.com has and did I mention it's open source!? With a LLM, you can go full loop back to Mermaid again after a few rounds of manual editing. "What a time to be alive!"

Ask HN: What development tools are you using for your current project?
I'm working on a personal project and found myself looking for an alternative to Postman/Insomnia this morning. This made me realize i've been using the same tools for so long for work (mobile development, finance) that this project may be a good time to try out some new things.
Here are a few tools that i've been using lately that I really enjoy:
https://pocketbase.io/ - A dead-simple self-hosted firebase/supabase-like "backend in a box" using golang and sqlite. So far i've been really impressed. I've gone the route of extending the base offering with more go code and am really enjoying the experience.
https://excalidraw.com/ - An open source whiteboarding tool. Slick to use and after learning some keybinds I've gotten pretty fast at throwing together diagrams to explain things to people on my team. The killer piece though is that the filetype is just json, so I can source control my diagrams. Even better, their "export to png" function has a box to embed the json data _into_ the png, allowing me to slap the diagram in places that only accept images (think confluence) and still be able to change the diagram later if needed. 10/10.
https://docs.gitlab.com/ee/ci/ - Gitlab's CI/CD toolset is really impressive, and I've gotten really intimate with it's deeper features over the past year. I'd be curious though to hear from someone who's familiar with it vs it's competitors.
