v1.0.0

[1.0.0] – 2025-06-06

Added

• Full alias system with support for:
  • .alias @NAME = EXPRESSION to define symbolic aliases
  • .unalias @NAME to remove existing aliases
  • Persistent storage of aliases via .repl_aliases (loaded and saved automatically)
  • Strict substitution with error reporting on undefined aliases
• Inline alias expansion (@name) with safe substitution in interpreter input
• Alias completion: @... names are now included in tab-completion
• .alias command with no arguments lists all active aliases
• Aliases now persist across REPL sessions, like history
• Aliases are expanded within .load, --file, and --run sources
• History tracking improved to avoid duplicate entries (e.g., with @X or !N)
• Unit test coverage for:
  • Alias substitution and protection
  • Error handling for undefined and malformed aliases
  • History interaction with .alias, .unalias, .load, and !N

Changed

• .load now supports alias definitions in input files (.alias @X = ...)
• The REPL no longer crashes if an alias is undefined; instead, a clear Alias error: ... is shown
• .help and tab completion dynamically reflect current alias list
• Alias definitions in .alias now expand other aliases during assignment (e.g., .alias @X = @Y or Z)
• Tab completion now unified across aliases, meta-commands, and interpreter keywords

Fixed

• Commands from .load or --file were not tracked in history — now correctly logged
• Previously, repeating the same input (e.g., @Z) added duplicate entries — now deduplicated
• Alias references like @A1 are no longer partially expanded (e.g., (True)1)
• Fixed inconsistent behavior when .alias was used within init files or scripts

Development

• Added full alias checklist covering edge cases, substitutions, and persistence
• GenericREPL cleaned and documented: inline comments clarified for core REPL logic
• Alias handling centralized and unit-tested (expand_aliases, handle_alias_command)
• Finalized and documented add_history_once() method to protect REPL history integrity
