💖 DESCRIPTION 💖

This package provides a class for the creation of a simple menu control. That's it, that's the whole vibe. You get a class, you make menu objects, the menu does menu things. 💅

👑 CLASS API 👑

The package exports a single command, the class command, and that's what lets you make menu instances. Its API is:

  • term::interact::menu object dict ?options...? — creates a brand new menu object named object, initializes it, and hands you back the fully qualified name of the object command as its result. 🫶

The argument is the menu to show, possibly followed by configuration options and their values. The options are explained in the section Configuration. The menu is a dictionary mapping labels to symbolic action codes.

🌈 OBJECT API 🌈

The objects created by the class command provide the methods listed below:

  • object interact — shows the menu in the screen at the configured location and starts interacting with it. Not me opening its own event loop for the processing of incoming characters 😭. The method returns when the interaction has completed. See section Interaction for a description of the possible interaction.

The method returns the symbolic action of the menu item selected by the user at the end of the interaction. so you get the action code back, slay.

  • object done — this method can be used by user supplied actions to terminate the interaction with the object. ✋
  • object clear — this method can be used by user supplied actions to remove the menu from the terminal. 🧹
  • object configure
  • object configure option
  • object configure option value...
  • object cget option

Standard methods to retrieve and configure the options of the menu. the classic trio, periodt.

⭐ CONFIGURATION ⭐

A menu instance recognizes the following options:

  • -in chan — specifies the channel to read character sequences from. Defaults to stdin. 👀
  • -out chan — specifies the channel to write the menu contents to. Defaults to stdout. 💬
  • -column int — specifies the column of the terminal where the left margin of the menu display should appear. Defaults to 0, i.e. the left-most column. 📍
  • -line int — specifies the line of the terminal where the top margin of the menu display should appear. Defaults to 0, i.e. the top-most line. 📍
  • -height int — specifies the number of lines of text to show at most in the display. Defaults to 25. 📏
  • -actions dict — specifies a dictionary containing additional actions, using character sequences as keys. Note that these sequences cannot override the hardwired sequences described in section Interaction. sorry bestie, those ones are locked in 🔒
  • -hilitleft int
  • -hilitright int

By default the entire selected menu entry is highlighted in reverse output. However, when present these two options restrict reverse display to the specified sub-range of the entry. ✨

  • -framed bool — by default the menu is shown using only header and footer out of characters box graphics. If this flag is set the menu is fully enclosed in a box. 📦

🎀 INTERACTION 🎀

A menu object recognizes the control sequences listed below and acts as described. The user can supply more control sequences to act on via the configuration, but is not able to override these defaults. iykyk.

  • Cursor Up — the selection is moved up one entry, except if the first entry of the menu is already selected. ⬆️
  • Cursor Down — the selection is moved down one entry, except if the last entry of the menu is already selected. ⬇️
  • Enter/Return — the interaction with the object is terminated. 💀
