"opam config var" was deprecared in version 2.1 and generates an error message in the process output:
[WARNING] var was deprecated in version 2.1 of the opam CLI. Use opam var instead or set OPAMCLI environment variable to 2.0.
The logic to create utop from utop-full is as follows:
- use ocamlobjinfo on utop-full to determine which modules are used
- use ocamlobjinfo on ocamlcommon, ocamlbytecomp, and ocamltoplevel to
determine which modules to exclude (a priori)
- compute the set used - (exclude - {Topmain,Toploop,Topdirs})
- call expunge with this set of modules
Previously, this was all done in expunge/expunge.ml, meaning core logic
+ process handling.
What this PR does is offload the process handling to dune: calling
ocamlobjinfo and expunge is done instead in dune rules, and
expunge/modules.ml is just about reading sets of module names and
outputing the result.
Besides simplicity and portability, the other advantage is that the
intermediate modules.txt can be inspected directly.
Fixes#428
The change in #418 introduced a regression if a `Unit` module in scope
does not have a `()` constructor in it.
This switches to the more explicit `Stdlib.Unit.()` path.
We are building a hidden expression that contains "()" but it is not
qualified. So it will pick the constructor in scope. This can cause
problems if `()` has been redefined. The correct fix is to qualify it as
part of the `Unit` module.
(additionally, this removes an unused ident)
Fixes#417
The utop code base is full of #if OCAML_VERSION to adapt to the changes
in compiler-libs. This has some issues - for example the corresponding
logic is harder to recognize, and some logic is duplicated in several
places. Also, this prevents using a formatter.
One medium-term goal is to move most of the compat functions to a new
Utop_compat module which would be the only place we use cppo.
This contains the "easy" cases - moving existing functions, etc. It is a
bit more difficult (and controversial) to convert pattern matching to
this pattern so it'll be done separately.
Exiting normally here refers to the `Exit_with_status` exception.
It is in particular triggered by `#quit;;` so we want to exit quietly
in that case.
Closes#398
* utop.el: always insert phrase terminator at the end-ish of input
When point is at the letter "n" in
utop[1]> let thi[n]g = 42
or in
utop[2]> let thi[n]g = 8734;
and the user presses C-j, it is always because they want to terminate
the expression at the end-ish of the input.
The unpatched behavior did not move point, and inserted two semicolons
in the middle of the expression.
Seems 9 years ago someone tried to extract types from the evaluation
results but never got this working. I think it's time for this code to
go away, given that we have much better options today (e.g. Merlin).
Utop supports a wide range of OCaml versions, but this is getting more
difficult to support. In addition, some of the dependencies we use do
not support 4.03-4.07, so utop can not be built on these versions.
