説明

Problem

When you type :? in nix repl you are presented with a list of 17 items, mostly sorted alphabetically by command name.

Due to people's limited ability to account more than ~5 objects of interest at a glance, it's improbable for beginners to find what they care about, and it's similarly improbable for most people to read through the list carefully.

Proposal

In order to make the available commands easier to discover and understand how they relate to each other, group the output of :? (source) by use case, for example:

  • evaluate
  • build
  • inspect
  • quit

調査方針
Examine the source file `src/libcmd/repl.cc` lines 486-503 to understand the current list of commands printed by `:?`. The goal is to categorize these commands into use case groups such as 'evaluate', 'build', 'inspect', and 'quit'. The implementation will require modifying the code to output grouped commands instead of a flat alphabetical list. Look for any existing grouping patterns in the codebase and consider how to structure the output for clarity.
