Crate reovim_module_snippet 

Snippet expansion module for reovim (#136).

Provides TextMate/LSP-compatible snippet expansion with intelligent tab stop navigation, placeholder mirroring, variable resolution, regex transforms, and choice support.

Architecture

• ast - Snippet element types (full EBNF grammar coverage)
• parser - Recursive descent parser (full TextMate/LSP grammar)
• engine - Active snippet tracking with position updates
• transform - Regex transform execution with case modifiers
• variables - Built-in variable resolver (TM_FILENAME, etc.)
• provider - Snippet provider trait and registry
• loader - JSON file loader (VSCode-compatible format)
• resolver - Mode key resolver for snippet navigation mode
• state - Per-client session extension state
• command - Command handlers (expand, jump next/prev, cancel)

Commands

• snippet:expand (<C-s> in insert mode) - Expand snippet at cursor
• snippet:jump-next (<Tab> in snippet mode) - Next tab stop
• snippet:jump-prev (<S-Tab> in snippet mode) - Previous tab stop
• snippet:cancel (<Esc> in snippet mode) - Cancel snippet navigation
