👋 Hi! I'm Roy; I'm from the UK 🇬🇧.

🔭 All my Open Source projects are published on Codsen org account, not here.

I wrote and maintain a broad spectrum of Open Source programs (npm handle royston, see npm-stat), for example:

• A big, CPU-bound program: detergent, email-comb
• Exports...
  • Both sync and async methods: json-comb-core
  • A regex: regex-empty-conditional-comments
  • A Set: html-entities-not-email-friendly
  • CSS as string: generate-atomic-css
  • 2ⁿ combinations of plain options object boolean values for unit tests: test-mixer
• Scannerless parser algorithm, processing the...
  • HTML: html-crush
  • CSS: string-extract-sass-vars
  • JSON: edit-package-json
  • TypeScript: tsd-extract
  • CSV: csv-split-easy
  • IANA language codes: is-language-code
  • Commitizen-generated CHANGELOG.md: lerna-clean-changelogs
  • human prose: string-apostrophes
• Variety of program API styles:
  • Classes-based API: ranges-push
  • Callback-only API: ast-monkey-traverse-with-lookahead
  • (One of a dozen) CLI: csv-sort-cli
• Stripping parsed tokens from HTML/CSS: stristri — done by traversing AST directly from a tokeniser — but I have an own AST traversing program too: 🐒 ast-monkey
• Parser, which produces our custom-design AST: codsen-parser
• Plugins:
  • Gulp plugin: gulp-email-remove-unused-css
  • ESLint plugin: eslint-plugin-row-num
• File streams: tap-parse-string-to-object
• Observer pattern using Node's EventEmmitter: emlint
• Fetches values from the internet: update-versions
• Unicode astral character-aware: easy-replace
• Backwards-engineering a 3rd party API: bitbucket-slug
• Recursion: ast-monkey-traverse
• Normalising the perf benchmark scores against a mock program: perf-ref
• String uglifier based on cryptography principles: string-uglify
• Reduce but over promises: json-comb (surprisingly a common pattern, used by CLI's which read multiple files in async)
