Tclint – chip design inspired dev tools for Tcl
I used to work at a small semiconductor startup that wrote chip design automation infrastructure in Tcl. One of our engineers wanted modern dev tooling for Tcl but couldn't find any - so I decided to build it. Since then, I've been working on tclint in my spare time. It now includes: - A linter (with plugins to support non-standard commands) - A formatter - A language server + VS Code extension tclint is already being used at my former employer and elsewhere. I have lots of ideas for improvements, such as more linter checks, better extensibility, deeper support for chip design formats (e.g.,…
In plain words
Tclint provides modern development tooling for the Tcl programming language, including a linter with plugin support for non-standard commands, a code formatter, and a language server with VS Code integration. Originally created to address the lack of contemporary tools for Tcl used in chip design automation, it is currently used at semiconductor companies and other organizations. The tool is actively developed with planned improvements including expanded linter checks, better extensibility, and enhanced support for chip design formats.

I have lots of ideas for improvements, such as more linter checks, better extensibility, deeper support for chip design formats (e.g., SDC-specific linter checks), and expanding the language server. If you write Tcl, give tclint a try! I’d love to hear if you find it useful, and I’d especially love suggestions on what would make it even better.

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
