Slint is a GUI toolkit, and is largely not relevant to concatenative programming. But the latest release adds a touch of postfix to the mix, which is nice to see. From the blog post: > ## Math Gains Postfix Support > > A subtle but profound change to the language. Traditional syntax: > > Math.max(20, Math.abs(value.x)) > > New postfix syntax: > > value.x.abs().max(20) > > The new syntax improves readability by making the transformation steps more explicit. It works well for many operations but has limitations: > > Effective for simple transformations (e.g., abs, max) Less intuitive for operations like clamp or atan2. > > pos.y.atan2(pos.x) // Less clear than atan2(pos.y, pos.x) > > So for now you cannot use postfix for all functions in the Math namespace. We may revisit these cases later, so give them a try and let us know your thoughts.

For me: Wezterm. It does pretty much everything. I don't think Alacritty/Kitty etc. offer anything over it for my usage, and the developer is a pleasure to engage with.
Second place is Konsole -- it does a lot, is easy to configure, and obviously integrates nicely with KDE apps.
Honorable mention is Extraterm, which has been working on cool features for a long time, and is now Qt based.

Just note that the comment was inaccurate, in that their weird encryption is indeed open source at least.

I'd say an important part of this calculator's interaction model is doing something, getting a result, then doing something else to that result. That's not too bad in the regular Python interpreter either.
For example, in Python:
>>> 5
5
>>> 4 + _
9
>>> 2 * _
18
In Stacker:
>>> 5
[5]
>>> 4 +
[9]
>>> 2 *
[18]
Does Hy have something like the Python interpreter's _
?

So it looks like a totally different data flow style, and (I think) geared toward writing then running programs, whereas Stacker is more for interactive stack-oriented calculator tasks.

I've never used Hy. Does it offer any concatenative-style interaction?

I suggest trying this one for Zsh, over the more common one: https://github.com/zdharma-continuum/fast-syntax-highlighting

As someone else said, setting less' jump value is helpful.
Another tool I use, mostly for the zshall manpage, is https://github.com/kristopolous/mansnip

I have a pip-tools wrapper thing that now optionally uses uv instead. Aside from doing the pip-tools things faster, the main advantage I've found, and what really motivated me to support and recommend uv with it, is that uv creates new venvs MUCH faster than python's venv module, which is really annoyingly slow for that operation.
Andy 4mo ago • 100%
I use my own Zsh project (zpy) to manage venvs stored like ~/.local/share/venvs/HASH-OF-PROJECT-PATH/venv
, so use zpy's vpy
function to launch a script with its associated Python executable ad-hoc, or add a full path shebang to the script with zpy's vpyshebang
function.
vpy and vpyshebang in the docs
If anyone else is a Zsh fan and has any questions, I'm more than happy to answer or demo.

From the author, on reddit:
Made a little mistake in there: you can create FDs with higher numbers using eg.
exec {fd}<>pipe
and they'll generate numbers above 10, plus the variables'll be better for scripting.
