Recent discussions on Discourse suggest that not all users know about apropos (or equivalently, using ?"..." for text search). The startup message currently mentions

Type "?" for help, "]?" for Pkg help.

I suggest that text search is added to this, but I am still looking for a compact way of phrasing it.

Consider the following system and its solution:

from sympy import *
from sympy.abc import j,f

# augmented matrix
a=Matrix([
[1,  1, 1,  1, 1,  1, 1,  1,  1],
[0, -1, 0, -1, 0, -1, 0, -1, -j],
[0,  0, 0,  0, 1,  1, 1,  1,  f]
])

x=Matrix(list(linsolve(a))[0])

# check if x is a solution
a[:,:-1]*x-a[:,-1] # should be all 0 but the second term is 'tau0-tau1'

Do you have an

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

Hi. I can imagine calendar options that would allow people to try different types of calendars. For example with lunar calendars like the Chinese, Vietnamese, Hindu, and Thai calendars.
I see this a powerful aid in teaching the importance of calendars and how they can help us relate to cosmic influences.
By the way... stellar work so far!

Expected behavior

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

Actual behavior

During "Creating SIF file..." step, the console does not produce any visible output for the user - but does create the resulting file eventually.

Steps to reproduce behavior

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

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

I think that the save status message currently doesn't ignore mouse input, so while it is on screen it's not possible to press GUI buttons.

We should add an option to be able to pass in an existing matplotlib Figure and list of Axes objects to PPSD.plot() as PPSD.plot(..., fig=None, axes=None) like we have for many other plotting routines. The purpose is to make it easier to make figures that have different PPSDs plotted in various subplots/axes. Compare [this post on discourse](https://discourse.obspy.org/t/plotting-ppsd-of-a

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