val add_ppx_context_str :
tool_name:string ->
Parsetree.structure_item list ->
Parsetree.structure_item list
Extract information from the current environment and encode it into an attribute which is prepended to the list of structure items in order to pass the information to an external processor.
val drop_ppx_context_str :
restore:bool ->
Parsetree.structure_item list ->
Parsetree.structure_item list
Drop the ocaml.ppx.context attribute from a structure. If restore
is true, also restore the associated data in the current process.
val add_ppx_context_sig :
tool_name:string ->
Parsetree.signature_item list ->
Parsetree.signature_item list
Same as add_ppx_context_str
, but for signatures.
val drop_ppx_context_sig :
restore:bool ->
Parsetree.signature_item list ->
Parsetree.signature_item list
Same as drop_ppx_context_str
, but for signatures.
Can be used within a ppx preprocessor to know which tool is calling it "ocamlc"
