Parser.Concrete
This module provides parsing APIs for downstream clients that are written in the traditional "initial" style which expects a concrete ADT representation for abstract syntax trees.
Logic in this module is implemented entirely on top of the tagless-final APIs provided in the Parser.TaglessFinal
module.
val parse_module :
context:Context.t ->
?enable_type_comment:bool ->
string ->
(Concrete.Module.t, Error.t) Stdlib.result
parse_module ~context input
takes the string input
and parse into a Python module. See documentation of Context.t
for the meaning of the context
argument.
Optionally an enable_type_comment
argument can be specified. If it is true, the parser will attempt to populate the type_comment
section of each AST node that has it. Otherwise, contents in comments will all get ignored and type_comment
will always be unset.
Calling this function is equivalent to calling TaglessFinal.parse_module
with spec
set to the return value of PyreAst.Concrete.make_tagless_final
.
val parse_expression :
context:Context.t ->
string ->
(Concrete.Expression.t, Error.t) Stdlib.result
parse_expression ~context ~spec input
takes the string input
and parse it into a Python expression . See documentation of Context.t
for the meaning of the context
argument.
Calling this function is equivalent to calling TaglessFinal.parse_expression
with spec
set to the return value of PyreAst.Concrete.make_tagless_final
.
val parse_function_type :
context:Context.t ->
string ->
(Concrete.FunctionType.t, Error.t) Stdlib.result
parse_expression ~context ~spec input
takes the string input
and parse it into a Python function type signature. See documentation of Context.t
for the meaning of the context
argument, and see documentation of TaglessFinal.parse_function_type
for the meaning of "function type signature".
Calling this function is equivalent to calling TaglessFinal.parse_function_type
with spec
set to the return value of PyreAst.Concrete.make_tagless_final
.
