dialog-rs/src, branch v0.2.0

Add the stdio backend

2019-01-11T02:32:45Z

This patch adds the stdio backend which acts as a fallback backend and uses standard input and output. For password queries, the rpassword crate is used to suppress output. Also, default_backend is changed to return Stdio if Dialog is not available.

Check DISPLAY environment variable in default_backend

2019-01-11T01:56:32Z

This patch changes the default_backend to also check the DISPLAY environment variable. If it is set, there probably is a X server running, so we try to use the zenity backend. Otherwise, the dialog backend is used.

Check the DIALOG environment variable in default_backend

2019-01-11T01:25:54Z

This patch changes the logic in default_backend to respect the DIALOG environment variable that may contain the name of the backend to use.

Return Box in default_backend()

2019-01-11T00:46:50Z

This patch refactors the default_backend function to return a Box instead of impl Backend. This will allow us to dynamically choose the backend implementation in a future patch. To keep the current interface, we change show_with to accept both a reference to a backend instance as well as a reference to a boxed backend instance. This also means we have to implement AsRef for the backend structs.

Implement Display for the Error enum

Move Error enum to the error module

2019-01-10T23:49:22Z

The trait implementations for the Error enum contain a lot of boilerplate code and are not very insightful. Therefore this patch moves the Error enum, its trait implementations and the related Result type definition from the main module to the error module. The Error and Result types are re-exported from the main module so that the public interface does not change.
