// This file holds a list of reserved symbols for the Rhai language.
|
|
//
|
|
// The mapped attributes are:
|
|
// - is this a reserved symbol? (bool)
|
|
// - can this keyword be called normally as a function? (bool)
|
|
// - can this keyword be called in method-call style? (bool)
|
|
//
|
|
// Generate the output table via:
|
|
// ```bash
|
|
// gperf reserved.txt
|
|
// ```
|
|
//
|
|
// Since GNU gperf does not produce Rust output, the ANSI-C output must be hand-edited and
|
|
// manually spliced into `tokenizer.rs`.
|
|
//
|
|
// This includes:
|
|
// * Rewrite the C hashing program (especially since it uses a `switch` statement with fall-through)
|
|
// into equivalent Rust as the function `is_reserved_keyword_or_symbol`.
|
|
// * Update the values for the `???_RESERVED_???` constants.
|
|
// * Copy the `asso_values` array into `RESERVED_ASSOC_VALUES`.
|
|
// * Copy the `wordlist` array into `RESERVED_LIST` with the following modifications:
|
|
// - Remove the `#line` comments
|
|
// - Change the entry wrapping `{ .. }` into tuples `( .. )`
|
|
// - Feature flags can be incorporated directly into the output via the `cfg!` macro
|
|
//
