Hello,
I have writted some ppx extension but I have a question,
Is there a proper way to add a start "file" structure.
I have try using the "structure" member of the mapper :
`
let new_mapper =
Ast_mapper.{
default_mapper with
structure = general_structure
}`
Where general_structure is just a
`my_begining_structure :: List.map (...)` but my begining
structure is repeated into each module. It is logic but I need
to add my own structure only at the begining of my file. In an
other project, I use a mandatory attribute ([@@@active_this_ppx]
for example), but imho, it is not a good approach.
Thanks a lot for your feedback and advices !
