Building Autocomplete for a Debug Console in Go
The article discusses the implementation of autocomplete feature for a debug console in Go. Autocomplete is an essential feature for a console as it saves typing and improves user experience. The article explains the syntax of console commands and the rules for generating completions. It introduces the concept of using a prefix tree (trie) data structure for autocomplete, but suggests using a sorted slice for better memory usage and faster lookup. The implementation of autocomplete involves generating a sorted slice of candidates, including opcodes, augmented operators, and paths. The article also mentions the use of reflection to walk the game state type and generate valid and exported paths. The author provides a naive implementation of path candidate generation using struct fields, but highlights its limitations. Overall, the article provides valuable insights into implementing autocomplete in a Go debug console.
