Tbh, I find it kind of weird that dune's own verbosity settings would affect mdx. Perhaps there should be an environment variable in mdx to control this?

That's sensible, I'll remove that change and push something in mdx.

If Dune should ouput ANSI colors to stderr, so can mdx. Signed-off-by: Antonin Décimo <[email protected]>

…, dune-rpc, dune-rpc-lwt, dune-private-libs, dune-glob, dune-configurator, dune-build-info, dune-action-plugin and chrome-trace (3.7.0~alpha1) CHANGES: - Fix parsing of OCaml errors that contain code excerpts with `...` in them. (ocaml/dune#7008, @rgrinberg) - Pre-emptively clear screen in watch mode (ocaml/dune#6987, fixes ocaml/dune#6884, @rgrinberg) - Fix cross compilation configuration when a context with targets is itself a host of another context (ocaml/dune#6958, fixes ocaml/dune#6843, @rgrinberg) - Fix parsing of the `<=` operator in *blang* expressions of `dune` files. Previously, the operator would be interpreted as `,`. (ocaml/dune#6928, @tatchi) - Fix `--trace-file` output. Dune now emits a single *complete* event for every executed process. Unterminated *async* events are no longer written. (ocaml/dune#6892, @rgrinberg) - Fix preprocessing with `staged_pps` (ocaml/dune#6748, fixes ocaml/dune#6644, @rgrinberg) - Use colored output with MDX when Dune colors are enabled. (ocaml/dune#6462, @MisterDA) - Make `dune describe workspace` return consistent dependencies for executables and for libraries. By default, compile-time dependencies towards PPX-rewriters are from now not taken into account (but runtime dependencies always are). Compile-time dependencies towards PPX-rewriters can be taken into account by providing the `--with-pps` flag. (ocaml/dune#6727, fixes ocaml/dune#6486, @esope) - Print missing newline after `$ dune exec`. (ocaml/dune#6821, fixes ocaml/dune#6700, @rgrinberg, @Alizter) - Fix binary corruption when installing or promoting in parallel (ocaml/dune#6669, fixes ocaml/dune#6668, @edwintorok) - Use colored output with GCC and Clang when compiling C stubs. The flag `-fdiagnostics-color=always` is added to the `:standard` set of flags. (ocaml/dune#4083, @MisterDA) - Fix the parsing of decimal and hexadecimal escape literals in `dune`, `dune-package`, and other dune s-expression based files (ocaml/dune#6710, @shym) - Report an error if `dune init ...` would create a "dune" file in a location which already contains a "dune" directory (ocaml/dune#6705, @gridbugs) - Fix the parsing of alerts. They will now show up in diagnostics correctly. (ocaml/dune#6678, @rginberg) - Fix the compilation of modules generated at link time when `implicit_transitive_deps` is enabled (ocaml/dune#6642, @rgrinberg) - Allow `$ dune utop` to load libraries defined in data only directories defined using `(subdir ..)` (ocaml/dune#6631, @rgrinberg) - Format dune files when they are named `dune-file`. This occurs when we enable the alternative file names project option. (ocaml/dune#6566, @rgrinberg) - Move `$ dune ocaml-merlin -dump-config=$dir` to `$ dune ocaml merlin dump-config $dir`. (ocaml/dune#6547, @rgrinberg) - Allow compilation rules to be impacted by `(env ..)` stanzas that modify the environment or set binaries. (ocaml/dune#6527, @rgrinberg) - Coq native mode is now automatically detected by Dune starting with Coq lang 0.7. `(mode native)` has been deprecated in favour of detection from the configuration of Coq. (ocaml/dune#6409, @Alizter) - Print "Leaving Directory" whenever "Entering Directory" is printed. (ocaml/dune#6149, fixes ocaml/dune#138, @cpitclaudel, @rgrinberg) - Allow `$ dune ocaml dump-dot-merlin` to run in watch mode. Also this command shouldn't print "Entering Directory" mesages. (ocaml/dune#6497, @rgrinberg) - `dune clean` should no longer fail under Windows due to the inability to remove the `.lock` file. Also, bring the implementation of the global lock under Windows closer to that of Unix. (ocaml/dune#6523, @nojb) - Remove "Entering Directory" messages for `$ dune install`. (ocaml/dune#6513, @rgrinberg) - Stop passing `-q` flag in `dune coq top`, which allows for `.coqrc` to be loaded. (ocaml/dune#6848, fixes ocaml/dune#6847, @Alizter) - Fix missing dependencies when detecting the kind of C compiler we're using (ocaml/dune#6610, fixes ocaml/dune#6415, @emillon) - Allow `(include_subdirs qualified)` for OCaml projects. (ocaml/dune#6594, fixes ocaml/dune#1084, @rgrinberg) - Accurately determine merlin configuration for all sources selected with `copy#` and `copy_files#`. The old heuristic of looking for a module in parent directories is removed (ocaml/dune#6594, @rgrinberg) - Fix inline tests with *js_of_ocaml* and whole program compilation mode enabled (ocaml/dune#6645, @hhugo) - Fix *js_of_ocaml* separate compilation rules when `--enable=effects` ,`--enable=use-js-string` or `--toplevel` is used. (ocaml/dune#6714, ocaml/dune#6828, ocaml/dune#6920, @hhugo) - Fix *js_of_ocaml* separate compilation in presence of linkall (ocaml/dune#6832, ocaml/dune#6916, @hhugo) - Remove spurious build dir created when running `dune init proj ...` (ocaml/dune#6707, fixes ocaml/dune#5429, @gridbugs) - Allow `--sandbox` to affect `ocamldep` invocations. Previously, they were wrongly marked as incompatible (ocaml/dune#6749, @rgrinberg) - Validate the command line arguments for `$ dune ocaml top-module`. This command requires one positional argument (ocaml/dune#6796, fixes ocaml/dune#6793, @rgrinberg) - Add a `dune cache size` command for displaying the size of the cache (ocaml/dune#6638, @Alizter) - Add 4.14.0 MSVC to CI (ocaml/dune#6917, @jonahbeckford) - Fix dependency cycle when installing files to the bin section with `glob_files` (ocaml/dune#6764, fixes ocaml/dune#6708, @gridbugs) - Handle "Too many links" errors when using Dune cache on Windows (ocaml/dune#6993, @nojb)

In watch mode, `$ dune exec` the executed binary whenever it is recompiled. (ocaml/dune#6966, @gridbugs) - `coqdep` is now called once per theory, instead of one time per Coq file.

With @maiste and @art-w we had a long debugging session with mdx. I think it'd be nice to have #6416 (arbitrary flags for mdx) but in the meantime enabling colors in mdx and having more logs when Dune runs in verbose mode is, imo, a good start.
