* Extract the menu action prompts to a function * Add a NERDTreeMinimalMenu configuration option If this option is set, Vim’s command line displays a single-line version of the menu: Which action? (a*/m/d/r/o/q/c/l): Pressing ‘a’ will call the ‘add child node’ menu item as that is its shortcut. The * denotes the position of the currently selected menu item which can be changed with NERDTreeMenuDown and Up in the usual way. The user may wish to set these to <left>, <right> or h, l if they prefer. * Minimise the text once a menu item is chosen If NERDTreeMinimalMenu is set, then echo a single line prompt after the menu item is chosen. This reduces noise for users who are already familiar with how the menu works and prevents Vim scrolling down to accommodate the menu text. If the directory is non-empty we display ‘Delete directory?’ instead of ‘Delete?’ and the user must still type ‘yes’ to confirm, rather than just pressing ‘y’. * Document the new NERDTreeMinimalMenu feature * Tweak the format for the minimal menu prompt As per @PhilRunninger’s suggestions: - The menu now shows the ‘j/k/enter’ help text - The first word of the selected item is shown* - Use commas between menu items so that it’s visually distinct from the ‘j/k/enter’ text * I tried displaying the full menuItem text, but this can be quite long, e.g. > (o)pen the current node with system editor This causes the menu to jump around a lot. We could add another minimal versions of these, but I think the first word seems ok for now.
