The motivation for this change is implement the --build-dir feature. This
feature lets us control the build directory which previously always defaulted to
_build. To accomplish this, Path.t had to be modified to be:
External of External.t | In_source_tree of Local.t | In_build_dir of Local.t
To represent the 3 kinds of paths dune is dealing with. The In_build_dir
constructor in particular, is relative to Path.root or some external path.
A few other refactorings had to be done to support this transition:
* The workspace is now "settable". This means that we no longer have to pass it
explicitly when converting local to absolute paths.
* Path.is_local no longer makes sense and is renamed to Path.is_managed.
Roughly, is_managed identifies paths in the build and source directories.
* Path.absoulte has been renamed of_filename_relative_to_initial_cwd
* Path.Local.root is now "." (as opposed to "")

- install two identical binaries: jbuilder and dune
- rename the man pages to dune-*
- change the name in man pages
- change the name of libraries
- add support for dune-project files and add a dune-project file
- add support for dune-workspace files
- start updating the manual
- update the tests
- make sure type t always come first
- Map.map, Map.fold, ... never pass the key to the callback while Map.mapi, Map.foldi, ... do
- removed the ~key and ~data labels, I find them useless and annoying
- Set.elements --> Set.to_list
- Map.bindings --> Map.to_list
- Map.of_alist --> Map.of_list
- added Ordering.t for comparison functions
- renamed Inl/Inr to Left/Right. The latter seems clearer
- moved List.longest to String.longest
- added a Pp module with a nicer API than Format
Lib module
----------
We have a new module Lib that replaces Lib, parts of Lib_db and parts
of Findlib. It is used to manage all libraries (internal and
extrernal). Lib.t represent a completely resolved library, i.e. where
all the dependencies have been resolved. Lib.Compile is used to
provide what is necessary to build the library itself. Lib.Meta
provides what is necessary to generate the META file for the library.
We also have library databases represented as Lib.DB.t. A library
database is simply a mapping from names to Lib.t values and and
created from a resolve function that looks up a name and return a
Lib.Info.t. A Lib.Info.t is the same as a Lib.t except that
dependencies are not resolved.
A library database can have a parent database that is used to lookup
names that are not found in the current database. In practice we have
the following hierarchy:
1. For every scope, we have a library database that holds all the
libraries of this scope. In this DB, a library can be referred by
either it's name or public name
2. the parent of each of these databases is a database that holds all
the public libraries of the workspace. In this DB libraries must be
referred by their public name
3. the parent of this DB is for installed libraries
(1) databases are accessible via Scope.libs
(Super_context.find_scope_by_{name,dir} sctx xxx)
(2) is accessible via Super_context.public_libs sctx
(3) is accessible via Super_context.installed_libs sctx
The dependencies of a library are always resolved inside the DB it is
part of. When we compute a transitive closure, we check that we don't
have two libraries from two different DB with the same name. So for
instance linting Base should now supported.
Jbuild.Scope_info
-----------------
Jbuild.Scope was renamed Jbuild.Scope_info
Scope module
------------
This replaces Lib_db. A Scope.t is now just a pair of a
Jbuild.Scope_info.t and a Lib.DB.t. Scope.DB.t is an object used to
lookup scopes by either name or directory.
We no longer have an external scope or special anonymous
scope. Instead one should use Super_context.installed_libs or
Super_context.public_libs depending on the context.
We are now computing the transitive closure of findlib packages
lazily. This simplify the code and prepare for subsequent changes to
library management.
Fix#484 at the same time
Before, jbuilder used to stop its execution after an error was
encountered. Now it continues until all branches have been explored.
To implement this feature, Future was rewritten as a Fiber module with
a simpler semantic.
This patch contains various other refactorings.
This commit introduces explicit scopes in Lib_db and refactors dune to use these
scopes where appropriate. Briefly, they are appropriate whenever we previously
used a directory to resolve the scope with Lib_db.find ~dir and friends. So a
Lib_db.Scope.t replaces a (dir, Lib_db.t) pair.
This allows to be explicit about the anonymous and external scope. Which is
important when building ppx drivers.
We also harmonize the error handling with the Findlib module. In both cases
we use a flat string list of errors. Rather than the more specific type we had
before in Findlib.
* Change jbuilder to load rules lazily
Rules are now loaded on a per directory basis as needed. This speed up
the start up time on large workspaces.
Does various refactoring as well.
* Simplify the handling of META files
We no longer generate a META.foo.from-jbuilder file. Nobody is using
this feature and it's making the new code more complicated.
Option to force running tests
The mechanism allows for forcing any alias, but only forcing tests is exposed to the user. Aliases are forced by deleting all the alias files that belong to a particular alias. The option for forcing tests is called --force.
Calling 'jbuilder build @path/x' always request the alias `x` in
`path` and all its descendant.
To implement that, change the build system interface to take an
arbitrary request as argument.
Add a utop subcommand that build and execute a utop where all the libraries defined in the current directory are immediately available for interactive use.
