CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
\$\{([^{}]+)\}   (flags: g)

Raw source: \$\{([^{}]+)\}

How it works

\$ matches the dollar sign. \{ matches the opening brace. ([^{}]+) captures one or more non-brace characters as the inner expression. \} matches the closing brace. The pattern won't handle nested braces (e.g. `${ {a:1}.a }`); for that you need a real parser, but this regex covers the common case.

  • ${name}
  • ${count}
