Add scale parameter to blackbody emitter [feature]

1

## Description This PR adds the `scale` parameter back to the `blackbody` emitter. This feature is ported from the old Mitsuba and is useful when scenes are not expressed in...

## Summary When running the tests on a fresh build of `master`, I get a segfault. ## System configuration - Platform: Arch Linux (Linux WHALE 5.11.10-arch1-1 #1 SMP PREEMPT Fri,...

Target a Gtk Cairo context

12

(Perhaps I've just missed it) We should document a way to have CairoMakie paint onto a GtkCanvas from Gtk.jl. Here is an example: ```julia using Gtk, CairoMakie c = @GtkCanvas()...

check whether numpy is installed before running Conda.add during build

5

Currently, there is a call to `Conda.add("numpy")`: https://github.com/JuliaPy/PyCall.jl/blob/3c66d9ea6d6c2166e11dece15b12335c24648e59/deps/build.jl#L78-L80 This call should be redundant per README: https://github.com/JuliaPy/PyCall.jl/blob/3c66d9ea6d6c2166e11dece15b12335c24648e59/README.md#L253 I suggest this call be removed, eliminating the need to access the internet when...

Support for alternative probability distributions (such as uniform)

4

For some engineering applications, it is very helpful to use uniform distributions rather than Gaussian distributions. Examples include statistical geometric tolerance stacks, round-off noise in signal processing, and worst-case timing...

I think it would be cool to be able to add a keybinding for e.g. running `fieldnames(typeof())` or a similar smarter alias when a shortcut key like CTRL+L is pressed....

https://github.com/symengine/SymEngine.jl/blob/826e6e910cf93ca84e0a855a7cc0fe185c6d6970/src/subs.jl#L33 Somewhat pathological, but would be good to protect against this: ``` using SymEngine @vars a subs(a) ```

Support for std::unordered_map

2

What would the process look like for adding support for `std::unordered_map`? I think it could map nicely onto a Dict.

Wondering if `readxml(::IOBuffer)` is a valid use case? ```julia # works xml = "Hello, World" @show parsexml(xml) # ERROR: LoadError: XMLError: Document is empty from XML parser (code: 4, line:...

RFC: add a `frommissing` function

1

This would be a parallel to [the `fromMaybe` function in `Data.Maybe` in Haskell](http://hackage.haskell.org/package/base-4.12.0.0/docs/Data-Maybe.html#v:fromMaybe). The definition would be sorta like this: ```julia frommissing(default::T, value::Union{Missing, T}) where {T} = ismissing(value) ? default...
