One of the main use cases of lpad and rpad is, at least for me personally, to align things in the terminal. However, lpad and rpad are defined (and documented) to work in terms of code units (i.e. they call length on the input string) which means that when length and textwidth disagree, you get unaligned output:

julia> s1 = "⟨k|H₁|k̃⟩"
"⟨k|H₁|k̃⟩"
julia> s2 = "⟨k|H₁|k⟩"
"⟨

See this issue sympy/sympy#11044 . That issue was fixed in PR sympy/sympy#11566. Though no test case was added for the lambdify.

What needs to be done?

Add test case that this works just fine:

>>> from sympy import MatrixSymbol, lambdify
>>> x = MatrixSymbol('x', 3, 1)
>>> f = lambdify(x, x.T*x)

Test case needs to

Description

The current docstring in the Spinner class demonstrates using s.next() to update the spinner. But this is a Python 2-ism that no longer exists for iterators in Python 3. Instead the correct documentation would be next(s).

Additionally, I think it's confusing

Expected behavior

Some progress or update information during the creation of the SIF file.

Actual behavior

Steps to reproduce behavior

I was executing a few “larger” builds through the bui

What is the feature ?

I'm trying out this library for the first time and I'm seeing several places where some shorthand functions would have been really pleasant:

1. Shorthand functions for Pos: Pos::top_right, Pos::bottom_right, Pos::bottom_center etc..
2. Short way to set colors for components. My plots are supposed to be white-on-black, which requires a lot of boilerplate on lots o

At least if the user hasn't taken a screenshot the open screenshots button just silently fails.
Instead it should show a warning popup that the folder doesn't exist and suggest taking a screenshot and then trying again.
The same probably also applies to the browse saves folder button so that should also have a warning popup, and suggesting the player to make a save first.

I think it's fine to

For the long term, we could clean up the code base a bit by internally using pathlib instead of os.path.join(....) and consorts. This is no vital or overly important task but it will help new contributors, to use it in new contributions and not introduce more old-style code, looking at the rest of the code base.

This is a pretty trivial (but longish) task and is a good first issue for new peo

We either do this all ourselves or do some reordering somewhere, I forget. But we should use the LaTeXML option now! brucemiller/LaTeXML#1044
