Describe the new feature

Similar to #188, I want to be able to capture the PuLP output and put it all in a single log line, rather than having it go to stdout directly. Instead of creating a temporary file and pointing PuLP to the log file, I would like to be able to get the log output as a string, similar

Suppose we have an input.json file in the current directory and foo is not a valid directory. Then

vroom -i input.json -o foo/output.json

fails to write any output. The return code is 0, which is somehow consistent with exiting silently.

We should really raise an error when writing to a file is requested and turns out to be impossible.

It would be nice if Choco were able to support MiniZinc output format.

The package I want to suggest the idea to: AngouriMath.Interactive

The current logo includes Jupyter logo which is incorrect (since you can use that pkg in VSC Notebooks or in console etc.).

Now that Convex.jl is backed by MOI, we can take advantage of its ability to write to file formats (https://jump.dev/MathOptInterface.jl/stable/apimanual/#File-formats-1). It's actually pretty easy to do this already, e.g.

using Convex, COSMO
x = HermitianSemidefinite(2)
p = minimize( real(tr(x)), tr(x * [1.0 im; -im 0]) == 0, x[1,1] == 1)
solve!(p, COSMO.Optimizer)

using MathOp

isQuestion() || sentence.isQuest() occurs frequently all over the place

Dear all,

This isn't really a bug, more like a small annoyance, but given the superb quality of this crate I figured I'd report it anyway... :)

On recent nightly (rustc 1.62.0-nightly (34a6c9f26 2022-04-13)), the generated code produces a compiler warning:

warning: unused doc comment
