Reporting unplottable types GiovineItalia/Gadfly.jl

The criteria for a type to be plottable is a little complex, so plotting is largely duck typed. This leads to indecipherable errors when a type can't be plotted. There should be an explicit check f...

signif: make base a keyword JuliaLang/julia

Noted here: https://github.com/JuliaLang/julia/pull/26056. `signif` is one of the last (the last?) function to take a positional `base` argument instead of it being passed as a keyword. It seems li...

StaticArrays not suitable for high dimensional systems JuliaDynamics/DynamicalSystems.jl

StaticArrays.jl is great, but not useful for large arrays that are associated with high-dimensional systems, Maybe one could use StaticArrays only for low dimensional systems (say up to 10 variable...

Make the `lyapunovs` function return only the k-th larger exponents JuliaDynamics/DynamicalSystems.jl

This is extremely simple: The only changes necessary are: 1. in the methods add an optional argument (NOT a keyword) e.g. `k::Int = dimension(ds)` 2. initialize the matrices `Q` and `K` in the...

is a Functor better than repeated closures? JuliaDynamics/DynamicalSystems.jl

There are two ways to create an e.g. `ContinuousDS`. One is to use closures, like it is done for almost all systems: ```julia function roessler(u0=rand(3); a = 0.2, b = 0.2, c = 5.7) @inli...

Allow non-uniform delay times for delay coordinates JuliaDynamics/DynamicalSystemsBase.jl

In a reconstruction interface, allow `τ` to also be a vector of integers, so that `D == length(τ) + 1`. If this happens, each reconstruction component has delay time `τ[i]` instead of a constan...

Add special printing for length method error JuliaLang/julia

A common mistake for people adding new iterators of unkown length is that they don't define the iterator type trait, so if they call things like `isempty` they get a `length` MethodError. We should...

Make `cumsum(A)` compute a summed-area table JuliaLang/julia

Change the name of the sort reverse keyword from `rev` to `reverse` JuliaLang/julia

(GLR) Avoid copying data with/without intercept tlienart/AnalyticalEngine.jl

At the moment there's a rather ugly ```julia X_ = glr.fit_intercept ? hcat(ones(n), X) : X ``` so if `fit_intercept` then potentially the `hcat` creates a new object in memory which is quit...

sprint: rename `env` keyword, add `size` keyword JuliaLang/julia

As observed in https://github.com/JuliaLang/julia/pull/24727, the `sprint` function takes an `env` keyword which could have a better name, e.g. `context`. All methods should accept that keyword. It...
