Module metavar_expr
Source - MetaVarExpr 🔒
- A meta-variable expression, for expansions based on properties of meta-variables.
- MetaVarExprConcatElem 🔒
- Indicates what is placed in a
concat parameter. For example, literals
(${concat("foo", "bar")}) or adhoc identifiers (${concat(foo, bar)}).
- RAW_IDENT_ERR 🔒
- UNSUPPORTED_CONCAT_ELEM_ERR 🔒
- check_trailing_tokens 🔒
- Checks if there are any remaining tokens (for example,
${ignore($valid, extra)}) and create
a diag with the correct arg count if so. - eat_dollar 🔒
- Expects that the next item is a dollar sign.
- iter_span 🔒
- Returns a span encompassing all tokens in the iterator if there is at least one item.
- parse_concat 🔒
- Parse a meta-variable
concat expression: concat($metavar, ident, ...). - parse_count 🔒
- Parse a meta-variable
count expression: count(ident[, depth]) - parse_depth 🔒
- Parses the depth used by index(depth) and len(depth).
- parse_ident 🔒
- Parses an generic ident
- parse_ident_from_token 🔒
- parse_token 🔒
- try_eat_comma 🔒
- Tries to move the iterator forward returning
true if there is a comma. If not, then the
iterator is not modified and the result is false. - try_eat_dollar 🔒
- Tries to move the iterator forward returning
true if there is a dollar sign. If not, then the
iterator is not modified and the result is false.
