dialog-rs/src/backends, 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 zenity backend

Add the Password dialog box

2019-01-08T19:55:54Z

Refactor io::Error into custom Error enum

2019-01-08T04:13:45Z

Add question dialog boxes

2019-01-08T03:54:39Z

Add input dialog boxes

2019-01-08T03:54:20Z

This patch implements input dialog boxes. This required some refactoring in the dialog backend to allow additional arguments after the width and the height.

backends/Dialog: Add support for output handling

2019-01-08T03:54:07Z

dialog(1) uses stdin to display the dialog boxes and prints output to stderr (if applicable). This patch changes the command invocation in the Dialog backend to capture stderr. stdin and stdout are inherited from the main process so that dialog can display the dialog boxes and receive user input.
