Nice - I'll give it props for: > 1 metre + 8 chain = 161.9344 m > 1 tonne + 1 short ton = 1.90718474 t > 1 tonne + 1 long ton = 2.0160469 t and give it a pass for not supporting pre 1963 UK | US historic weights and measures .. that's getting into a pretty specific use case where Standards nerds like to have a clear display of what conversion factors are in play and what provenance those factors have. Time Zone suppo…

You're right, I'm using lz-string to compress the text before shoving it in the URL. This is definitely a necessary evil for the time being so I don't need a back end component to the app. But eventually I do want prettier URLs and collaborative editing if I can make that work without it bankrupting me or driving me insane.

For what it's worth, the typescript playground takes the exact same approach as you, placing a compressed (lz-string) copy of the text after the #code/ in a sharing url.

This looks pretty cool. I've long been looking for something similar to Soulver ( https://soulver.app/ ) that I can use on Linux. This seems promising. One small criticism: In my opinion, no web-based writing app is useful unless the tab key inserts a tab. The default behavior of most browsers to move focus to the next field is tremendously infuriating in this context. Unfortunately, that's what happens here, at leas…

SoulVer on macOS as you know. OpalCalc on Windows. Speedcrunch on all three platforms, though I will categorically state that whilst Speedcrunch is very good, it is no Soulver/OpalCalc.

Impressed you found that. I don't have anything set up to automatically update it currently, but I do have an intention to have something set up to automatically update it.

Btw the conversions don't seem to work for me: > 100 eur to usd $-100.63 > 100 usd to eur Incompatible units

The right operator for unit conversions is "in." "to" is used for ranges, so it's doing 100 euros _goes to_ 1 us dollar and giving you back the answer in dollars.

But it seems the parser is breaking when trying to do the inverse, anyway: "100 usd in eur" seems to do "e*ur" and gives "Values must be converted to units."

Might not be as comprehensive as Soulver, but here's something I've been using in a browser to fiddle with: https://cruncher.io/ .

Gosh, everyone has made one of these haven't they?

Not everyone! About five people from a population of six billion. And you’re one of them.

Yours looks great. Well done on the release.

Line 100 might have an error though? It isn’t recognising `30th Sept`, does it not like the final `t`?

I've made this one and use it daily: https://github.com/filipesabella/calcpad It's electron though, if that's important to you.

Hey this is pretty cool. Instead of Electron app I would prefer it as a browser tab. Wish it could be self hosted.

Thanks!

You can use the web version, it's all offline and saved in localStorage. Works well in mobile too and can be "installed" as an app from there.

Nice app - I like the workspace sharing feature. It would be nice if "1 mm / inch" would be returned as a unitless number. I know that you can enter "1 mm in inch" but there are cases where it would help to have the calculator reduce the units for you.

For what it's worth, `1 mm/inch in 1` seems to work as expected.

One thing it's missing which is trivial to implement. Have a little checkbox adjacent to line numbers, default true, that when unchecked would simply not parse the calculations, just leave it as simple text.

This way writing "and here is a little example of 9^9^9" and simply copy paste that to next line would allow me to not have it evaluate on text, but only on next line. OF course, a little more complicated to implement would be next step of actually select the text and within the pop-up have "Don't evaluate". This way writing a documentation without having always calculation be in your way would be very easy.

Other than that, this looks great ma' dude. Keep it up!

I wanted to see how this would run in redbean[1], and it runs fantastically!

If you wanna see this in a little executable that you can pass around to your friends, check out this repo I threw up: https://github.com/shmup/redbean-calcpad

This is now essentially an offline CalcPad that still leverages LocalStorage, since the UI is your browser. I've configured this specific build to automatically launch your default browser when you run it.
