* Fix clippy complaints that don't change the semanticsStephan Sokolow2019-10-25

* Fix input and password dialogs for zenity backendRobin Krahl2019-06-30
| | | | | | | | Previously, we tried to read the user input from zenity’s stderr although it is written to stdout. This patch changes the zenity backend to read from stdout instead of stderr. It also removes trailing newlines from the user input, as zenity adds a newline when writing the input.
* Add the stdio backendRobin Krahl2019-01-11
| | | | | | | 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_backendRobin Krahl2019-01-11
| | | | | | | 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_backendRobin Krahl2019-01-11
| | | | | 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<dyn Backend> in default_backend()Robin Krahl2019-01-11
| | | | | | | | | | This patch refactors the default_backend function to return a Box<dyn Backend> 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<Self> for the backend structs.

* Add input dialog boxesRobin Krahl2019-01-08
| | | | | | 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 handlingRobin Krahl2019-01-08
| | | | | | | | 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.
* Implement message boxes using the dialog backendRobin Krahl2019-01-08
This patch adds a first dialog box type, message boxes, and a first backend, the dialog(1) tool. It does not yet address the problems of output handling and backend selection.
