TODO.md

To Do

• posting
• analytics
• options report (across all backends)
• Support for ?testurl= query string parameter

Move to Regex.zone

• /support/links.html: move to Regex.zone
• /support/similar.html: have a page on Regex.zone
• /support/engines.html: skip (or include ones that aren't enabled? or page on Regex.zone?)
• redirects for bookmarks and rss feed

Share Codes

• bounce to regex.zone to save
• accept handle when returning
• load from regex.zone if handle is passed in (querystring)
• load from legacy if handle is old format
• form on home page to enter it
• if handle passed: overwrite/append/save new instead of save
• or somehow tell if handle has update permissions
• setup redirects for existing share codes

Engines

• Rust (started)
• Bun
• PostgresQL with golang server instead of Python. Or pglite
• Swift
• MySQL
• Free Pascal
• Erlang
• Elm
• Julia
• Haskell (done, but hosting isn't working)
• AWK
• D
• GNU grep
• Zig
• direct to engines: PCRE, RE2, ICU, hyperscan/vectorscan, Yarr...
• Janet ~lisp
• marianobarrios/dregex - Java alternative
• Mozilla's list of JavaScript implementations, each of which should support Regex.

Patterns that are not regular expressions:

• wildcards - lots of flavors
• Lua
• picomatch

Other lists:

• benchmarked list
• mariomka/regex-benchmark

Future

• toggle to multiline inputs
• /advanced/options.html: probably want to redo how these work (each service has 2-way map of specific:common)
• colorizer
• translations
• Fuzzing
• Non-regex pattern matching
• tags for each engine: features supported, calling languages, implementation language
• get engine release level (and everything else?) from remote instead of hard-coded
