Query Syntax

Overview

This document provides a BNF description for Hub query grammar.

Grammar

<Query> ::= <OrExpression> EOF
         <OrExpression> ::= <AndExpression> "or" <AndExpression>
         <AndExpression> ::= <SignExpression> "and" <SignExpression>
         <SignExpression> ::= ("not")? <Item>
         <Item> ::= <Field>| <Tuple>| <Paren>| <Phrase>| <Text>
         <Field> ::= <FieldName> ":" <FieldValue>
         <Tuple> ::= <TupleName> "(" <Field> <Field>* ")"
         <Paren> ::= "(" <OrExpression>| EOF ")"

Grammar is case-insensitive.

<Text> — arbitrary text.
<Phrase> — exactly text to match.
<FieldName> — field name (id, name, etc.). It covers all available JSON field names + some additional like "is", "in", "has", etc.
<FieldValue> — attribute value (admin, global, {my global permission}, etc.) for not single worded values value should be surrounded with "{" "}"
<Tuple> — conditional match by fields (access(project: "myProject", with: "myRole"))

Samples
