Roadmap

[marcioAlmada]

• Pick a more ergonomic composition identifier (instead of middle dot ·), before the DSL leaves draft state. Done: $( and )
• Literal matchers and expansions
• Token type matchers and expansions like T_TYPE·label. Ex: T_STRING·name
• Greedy layer matching and expansion {···label}, [···label], (···label)
• Non dominant macros (macros that only expand if fully matched and never throw errors during matching)
• Macro escaping (cloaking) syntax #9
• Dominant macros (macros that throw syntax errors if not fulfilled after a given entry point) #6
• (Partial) Expansion iteration like ·matched_scope ··· { ·a ·b ·c }
• Make expansion context unpacking become recursive #10
  • Maybe allow index access on expansions: ·matched[0] ·matched[2] ·matched[1]
• Allow control of trailing elements during ast unpacking #21
• Disallow infinite recursion by default while expanding macros #2
• Allow macro to refer to itself with ·this
• Macro hygiene #8
• Macro tags #4
  • ·recursion tag to force a macro to be recursive #5
  • maybe allow tag parameters, like ·recursion(limit => 3)
• Add more high level parsers
  • ·expression() or ·exp()
  • ·midrule(function($ts){...})
  • ·ls(...)
  • ·word()
  • ·label()
  • ·string()
  • ·variable()
• Add more high level expanders @
  • ·stringify(...)
  • ·concat(...)
  • ·eval()
• Allow operator precedence and infix macros declarations
• Allow macro importing between files like use macro some\file{macro_name} (right now macros are limited to be local per file)
• Global macros #28
• Support user defined parsers and expanders (add proper D.I for DSL lookups)
• Real time mode: pass included files through the preprocessor automatically #11
  • Provide a stream wrapper for pre processing inclusion include 'yay://some_file.php';
  • Composer integration
  • Make it fast enough
    • Disable complex errors by default #7
    • Optional: create a goto based parser stack interpreter and try to save tons of function calls
• Write more documentation

[chris-kruining]

have you by any chanche written down somewhere waht you want with the composer integration part? maybe I could help out with that 😄

[marcioAlmada]

@chris-kruining there are two alternatives for composer integration. One is using preprocess and the other is using Xray and loading the preprocessor callback before anything else.
