Adds a message indicating the user's ability to :save or :pipe a message with an unsupported mimetype and also adds a selector widget (similar to the tutorial). The selector widget was previously defined in the account wizard module, so this commit breaks it out into its own module to allow for re-use. Further, modify the BeginExLine() function to take an argument that pre-populates the command line, allowing functions to initiate an ex command without executing it. Closes #95.
Previously removing a tab would always pop from the history of tabs. This checks to see if the closing tab is the one selected, if it is then we use the history, otherwise we only need to change the selected tab if it was after (to the right of) the closing tab, in which case we just decrement the selected index.
A tab can now only be pushed onto the history if it is a selectable tab.
After removing a tab we should focus the newly selected tab if it is Interactive. This ensures things like the terminal get drawn properly.
This adds the Mouseable interface. When this is implemented for a component that item can accept and process mouseevents. At the top level when a mouse event is received it is passed to the grid's handler and then it trickles down until it reaches a component that can actually handle it, such as the tablist, dirlist or msglist. A mouse event is passed so that components can handle other things such as scrolling with the mousewheel. The components themselves then perform the necessary actions. Clicking emails in the messagelist opens them in a new tab. Textinputs can be clicked to position the cursor inside them. Mouseevents are not forwarded to the terminal at the moment. Elements which do not handle mouse events are not required to implement the Mouseable interface.
Choose the readline defaults for the behavior of these two functions/keybindings. Depending on the program, either of these can delete the whole line. Note that by default in [compose], <C-k> is bound to :prev-field<Enter>. Leave it up to the user whether or not they want to rebind the key in [compose].
Separatiing the ui code from aerc makes it usable as a library in other projects.
Add a "new-message-bell" option to the UI section of aerc.conf. A new hook into the message store allows the msglist widget to detect new messages being added to the displayed list. When new messages are delivered, and the new-message-bell option is enabled (as it is by default), the terminal will beep.
Tabstrip didn't take into account the width of the context. Now, it just shows as many tabs as can fit and truncates the last one if necessary. In future it probably would be best to ensure that the selected tab is rendered on the screen.
This adds tab completion to textinput components. They can be configured with a completion function. This function is called when the user presses <tab>. The first completion is initially shown to the user inserted into the text. Repeated presses of <tab> or <backtab> cycle through the completions list. The completions list is invalidated when any other non-tab-like key is pressed. Also changed is some logic for current completion generation so that all available commands are returned when <tab> is pressed with no current text and similarly for arguments of commands.
