A playground application is available at [overlay.speakeasy.com](https://overlay.speakeasy.com/) +JSONPath Plus extends the standard JSONPath specification with powerful context-aware operators, type selectors, and navigation features.

Grammars outside RFC 9535 are not in scope. +**Key benefits:** +- **100% backward compatible** with RFC 9535 - all standard queries work unchanged +- **Context variables** (`@property`, `@path`, `@parent`, etc.) for advanced filtering +- **Type selectors** (`isString()`, `isNumber()`, etc.) for type-based filtering +- **Parent navigation** (`^`) for traversing up the document tree ## Installation -This application is included in the [speakeasy](https://github.com/speakeasy-api/speakeasy) CLI, but is also available as a standalone library. - -## ABNF grammar - -``` - jsonpath-query = root-identifier segments - segments = *(S segment) - - B = %x20 / ; Space - %x09 / ; Horizontal tab - %x0A / ; Line feed or New line - %x0D ; Carriage return - S = *B ; optional blank space - root-identifier = "$" - selector = name-selector / - wildcard-selector / - slice-selector / - index-selector / - filter-selector - name-selector = string-literal - - string-literal = %x22 *double-quoted %x22 / ; "string" - %x27 *single-quoted %x27 ; 'string' - - double-quoted = unescaped / - %x27 / ; ' - ESC %x22 / ; \" - ESC escapable - - single-quoted = unescaped / - %x22 / ; " - ESC %x27 / ; \' - ESC escapable - - ESC = %x5C ; \ backslash - - unescaped = %x20-21 / ; see RFC 8259 - ; omit 0x22 " - %x23-26 / - ; omit 0x27 ' - %x28-5B / - ; omit 0x5C \ - %x5D-D7FF / - ; skip surrogate code points - %xE000-10FFFF - - escapable = %x62 / ; b BS backspace U+0008 - %x66 / ; f FF form feed U+000C - %x6E / ; n LF line feed U+000A - %x72 / ; r CR carriage return U+000D - %x74 / ; t HT horizontal tab U+0009 - "/" / ; / slash (solidus) U+002F - "\" / ; \ backslash (reverse solidus) U+005C - (%x75 hexchar) ; uXXXX U+XXXX - - hexchar = non-surrogate / - (high-surrogate "\" %x75 low-surrogate) - non-surrogate = ((DIGIT / "A"/"B"/"C" / "E"/"F") 3HEXDIG) / - ("D" %x30-37 2HEXDIG ) - high-surrogate = "D" ("8"/"9"/"A"/"B") 2HEXDIG - low-surrogate = "D" ("C"/"D"/"E"/"F") 2HEXDIG - - HEXDIG = DIGIT / "A" / "B" / "C" / "D" / "E" / "F" - wildcard-selector = "*" - index-selector = int ; decimal integer - - int = "0" / - (["-"] DIGIT1 *DIGIT) ; - optional - DIGIT1 = %x31-39 ; 1-9 non-zero digit - slice-selector = [start S] ":" S [end S] [":" [S step ]] - - start = int ; included in selection - end = int ; not included in selection - step = int ; default: 1 - filter-selector = "?"
