To the OP, congratulations for stopping procrastination. :-) I like the idea of your project,I'm often in need of a little tool to help quickly calculate some finance related data. In this case, I often launch a LibreOffice sheet but it is rather heavy for what I need. I'll give your tool a try. If you are looking for having notecalc3 running locally, the github[0] repository has all the installation instructions (not found in the documentation) [0] https://github.com/bbodi/notecalc3
In NoteCalc 0.4.0
This looks fantastic. I will definitely give it a spin. I've been tracking what I call "computational scratchpad" apps for a while now but haven't found one that fits my environment/workflow yet. Maybe Heynote will. Here are some others that I've looked at: * https://soulver.app Granddad of them all, Mac-only, proprietary, expensive * https://numi.app Mac-only, proprietary, semi-expensive. Has a Github and claims to be MIT-licensed but I don't see how you could build a working application with what's in the repo. * https://calca.io Windows- and Mac-only, proprietary, not expensive, nice docs. * https://notepadcalculator.com Web-based, not open source, hosted but uses local storage. You can optionally create an account to sign in and have your notes saved in plaintext on his server. * https://github.com/bbodi/notecalc3 Web-based, open sour

ce, self-hostable. But it seems to save your document in the URL string itself, which means the URL gets updated with almost every keystroke. Worth it for quick calculations and very small notes, I guess. * https://numpad.io Web-based, hosted, not open source. Also stores entire doc in URL, but doesn't update the URL bar the whole time you're typing. * https://numbr.dev/ Web-based, hosted. Has a Github but is not open source and the repo does not have all the bits needed to self-host it. Stores entire doc in URL. * https://github.com/metakirby5/codi.vim Vim/NeoVim plugin that is less like a "smart notepad" and more like Jupyter but with results printed on the right side of the screen instead of in a cell below. Supports lots of programming languages.

Hi, thanks :) Why WASM: One of the primary goal of NoteCalc is to be easily accessible (e.g. it was mainly born because Soulver is MacOS only). So the browser-based client was obvious choice, and I chosed WASM for - performance reasons - to be able to use rust - to avoid as much JS (and related technologies) as possible Why Canvas: I answered here: https://github.com/bbodi/notecalc3/issues/6#issuecomment-749... In a previous versions, only the changed areas were re-rendered, but the code was much more complex and error-prone, and it did not bring any performance improvement, so now I just rerender everything, still excellent performance but much simpler code. However this is different for calculations, only changed/affected lines are reparsed and recalculated.
