## v0.11
|
||
|
|
|
||
|
|
- Depend on ppxlib instead of (now deprecated) ppx\_core, ppx\_driver and
|
||
|
|
ppx\_metaquot.
|
||
|
|
|
||
|
|
## v0.10
|
||
|
|
|
||
|
|
- Added new `[@@deriving sexp]` record-field attribute, `[@sexp.omit_nil]`, for
|
||
|
|
a field that is omitted if its sexp representation is `()`.
|
||
|
|
|
||
|
|
- Improved `[%sexp_of: 'a]` and `[%of_sexp: 'a]` to not expose variable names
|
||
|
|
intended for internal use.
|
||
|
|
|
||
|
|
## v0.9
|
||
|
|
|
||
|
|
## 113.43.00
|
||
|
|
|
||
|
|
- Fix generator for polymorphic types where var names clashes with type name: `type 't t = ...`
|
||
|
|
|
||
|
|
## 113.33.00
|
||
|
|
|
||
|
|
- Clean up the documentation for sexplib, modernizing it to include
|
||
|
|
`ppx_sexp_conv`, and breaking up the documentation between sexplib and
|
||
|
|
`ppx_sexp_conv`. Also changed the formatting to use org-mode, so it
|
||
|
|
will render properly on github. Markdown doesn't render well by
|
||
|
|
default, unless you use quite different conventions about linebeaks.
|
||
|
|
|
||
|
|
## 113.24.00
|
||
|
|
|
||
|
|
- Trying to improve the tests in ppx\_sexp\_conv because they are a mess.
|
||
|
|
At least all tests are automatic now. And more things are tested like
|
||
|
|
the sexpification of exceptions.
|
||
|
|
|
||
|
|
- Update to follow `Type_conv` and `Ppx_core` evolution.
|
||
|
|
|
||
|
|
- Make ppx\_sexp\_conv correctly handle aliases to polymorphic variants:
|
||
|
|
|
||
|
|
type t = ` `A ` `@@deriving sexp`
|
||
|
|
type u = t `@@deriving sexp`
|
||
|
|
type v = ` u | `B ` `@@deriving sexp`
|
||
|
|
|
||
|
|
Before, `v_of_sexp` would never manage to read `B. This problem is
|
||
|
|
now fixed if you use `sexp_poly` on `u` instead of `sexp`, and if you
|
||
|
|
don't, you get an "unbound value __u_of_sexp__". People should use
|
||
|
|
`sexp_poly` when they have a polymorphic variant type that is not
|
||
|
|
syntactically a polymorphic variant, but in practice it's simpler to
|
||
|
|
replace `sexp` by `sexp_poly` when faced with the error above.
|
||
|
|
|
||
|
|
The need for `sexp_poly` should happen only in one new case: an
|
||
|
|
implementation says `type u = t `@@deriving sexp`` but the interface
|
||
|
|
says `type u = ``A` `@@deriving sexp``. (the old case where it was
|
||
|
|
already needed is when you have an interface that says `type u = t
|
||
|
|
`@@deriving sexp`` and in some other implementation you try to say
|
||
|
|
`type t = ` That_module.t | `A ` `@@deriving sexp``).
