This package looks awesome, but obviously has a bit of code rot. Has anyone gotten it to run lately?

I made an attempt and fixed a few dozen easy deprecation errors, but am unsure how to correct some of the finalizer related errors without reading up some more on low-level Julia.

TODO

1. Account for window size in q output.
2. Detect incomplete input and allow entering multi-line commands.
   • Start with simply detecting unbalanced parentheses.
3. Suppress output from commands ending in ;.
4. Write tests.

As described in https://discourse.julialang.org/t/ann-plans-for-removing-packages-that-do-not-yet-support-1-0-from-the-general-registry/ we are planning on removing packages that do not support 1.0 from the General registry. This package has been detected to not support 1.0 and is thus slated to be removed. The removal of packages from the registry will happen approximately a month after this issue is open.

To transition to the new Pkg system using Project.toml, see https://github.com/JuliaRegistries/Registrator.jl#transitioning-from-require-to-projecttoml.
To then tag a new version of the package, see https://github.com/JuliaRegistries/Registrator.jl#via-the-github-app.

If you believe this package has erroneously been detected as not supporting 1.0 or have any other questions, don't hesitate to discuss it here or in the thread linked at the top of this post.

TODO

1. Implement J) language for kdb+. #7.
2. Install q components in Pkg.build("JuQ"). #8.
3. Detect presence kdb+ symbols in executable and don't load c.so. #10.
4. Rethrow exceptions and convert some returned scalar values. #29.

When running in a client, @q_cmd should turn the given string to K_Chars and leave it that way. The run(cmd) command and function call on K_Chars objects should be implemented to send commands to the default server.
