Oils 0.21.0 TODO

[andychu]

A bunch of polish over Oils 0.20.0

• OSH
  • Brace expansion compatibility (Simon Michael)
  • ESRCH bug with pipelines and interactive shell -- multiple people ran into this
• Docs
  • publish ref check metrics
  • doc/error-catalog.md - var/setvar, \\ rules, OILS-ERR-10
• Translation
  • Fix flag spec bug
  • Fix all bugs? delta cpp OSH = 4 and delta cpp YSH = 11, so it's within reach
• YSH
  • const x bug - 'const c' without null on RHS can be re-declared #1784
  • @() semantics -- @() should decode J8 lines #1126
  • try { } should be the only form for simplicity #1785
  • ysh-0.20.0$ echo b'byte \xff' #=> Traceback #1826
  • Disallow proc / func keywords in OSH to avoid misleading syntax errors #1762
  • Parsing bug with comma after typed arg #1850
  • Typed args and block arg can get confused #1849
  • [YSH] setglobal d.key mutates local instead of global #1841
  • rename toJ8() fromJ8() -> toJson8() fromJson8()
  • more breaking changes like shopt --unset copy_env
  • argv and proc simplifications mentioned on blog
• J8
  • J8 refactor to remove self.spaces
  • json/json8 builtin should take named args, not flags
• ASDL
  • omit shared ref in C++ (already done in Python)

---

LATER, deferred

• Other YSH
  • Eggex names exported by ~
  • Str => replace() could take a function (low priority)
  • is there anything with REG_NOTBOL?
• J8
  • line-based error messages for J8 - also affects NIL8
  • check max code point in survey, json string, j8 string, code string
• ASDL
  • maybe try to export LST into NIL8
  • line wrapping algorithm for JSON, NIL8, and eventually OSH and YSH
• Yaks / NIL8
  • write fibonacci program and compile it
  • Pea exports fibonacci program to Yaks

(much later: rewrite Yaks in Yaks, with NIL8 as IR for ASDL, re2c, and Ninja. Some of this can go on the blog.)
