- Add a `-I` option that allows defined modules to be available from other
directories
- Add reporting of the number of successful / failed tests
- Locate the project root, and always run the commands from there
it is useful e.g. to be able to print intermediate ASTs when they don't type, to
debug the typing errors. This is better than commenting the typing line each
time.
Note that the option is not available on all targets (esp. not for ocaml and
python outputs ; it's allowed on the interpreters for debugging purposes but I'm
not sure if that's a good idea)
this is more consistent, avoids empty stamp files and should make things simpler
overall.
The slightly tricky `-C` option is added to Catala so that it can be run from
_build while paths to source and destination files are still specified relative
to CWD (Ninja doesn't provide string manipulation, so otherwise we would have to
explicit both the `_build/dir/` and `dir/` versions of each path).
* Obsolete code for included tests has been removed
* The engine uses a proper lexer and is much simplified
* An inline test in the middle of the file now only "sees" the file up to that
point. This fixes an issue where we had spurious errors when a type error was
added at the end of a file, and it would pop up in tests before it. This makes
files including many tests much more practical.
* diffing and resetting the tests has been reintroduced (done at the moment in
Ninja, but for more control (count number of failed tests, etc.) we could put it
back into Clerk at some point
* The Catala CLI can now take an input from stdin (with the possibility to link
a (possibly fake) on-disk file for error reporting and file locations ; this
is useful for running tests)
Rather than require all files to be listed on the command-line (and having to
check consistency with `> Using` directives), the main catala CLI is now a bit
more clever.
⇒ There is a new assumption that a module name definition must match the file
name (up to case and extension) — with appropriate error handling to enforce it.
In exchange, `> Using` directives are now used to more transparently lookup the
appropriate `.catala_*` interfaces and the compiled artifacts for the used modules (handling transitive dependencies), with just standard `-I` flags for when they need to be looked up in different places.
- Use separate functions for successive passes in module `Driver.Passes`
- Use other functions for end results printing in module `Driver.Commands`
As a consequence, it is much more flexible to use by plugins or libs and we no
longer need the complex polymorphic variant parameter.
This patch leverages previous changes to use Cmdliner subcommands and
effectively specialises the flags of each Catala subcommand.
Other changes include:
- an attempt to normalise the generic options and reduce the number of global
references. Some are ok, like `debug` ; some would better be further cleaned up,
e.g. the ones used by Proof backend were moved to a `Proof.globals` module and
need discussion. The printer no longer relies on the global languages and prints
money amounts in an agnostic way.
- the plugin directory is automatically guessed and loaded even in dev setups.
Plugins are shown by the main `catala` command and listed in `catala --help`
- exception catching at the toplevel has been refactored a bit as well; return
codes are normalised to follow the manpage and avoid codes >= 128 that are
generally reserved for shells.
Update tests
The upside of this is that each command can define specific flags ; there is a
small loss of backwards-compatibility in that the command needs to be the first
argument.
`catala --help` will now only show a summary of commands, with more specific
manpages shown on `catala CMD --help`.
Another point is that the plugin interface is extended to allow plugins to be
registered as subcommands and have their own flags (this will be very useful for
adding flags to the lazy/dot/explanation plugin that has many options).
Note that no efforts has yet been made to specialise the options, the previous
type was just made global for all subcommands.
This is a hack, but not a dirty one: a new command `catala pygmentize` is added,
which is just a wrapper around `pygmentize` that calls it with the proper lexers
defined.
The point is that this needs no installation, just a stock `pygmentize`
installation and the `catala` binary.
Changelog:
---
A lot has been going on, with more than 530 patches and 70 PRs merged since
0.7.0 last summer. In summary:
- Quite a lot of syntax improvements and changes. Checkout the latest
[cheat-sheet](https://catalalang.github.io/catala/syntax.pdf) for an overview
- Allow local `let ... equals ... in ...` definitions
- Better error messages and positions throughout
- Added the ability to directly call a scope and retrieve its outputs, like a
function
- Added disambiguation, allowing to access structure fields without specifying
the structure type each time
- Added automated resolution of operators, allowing e.g. to write just `+` in
place of all the type-specific operators `+.`, `+$`, `+@`, `+^`, etc.
- More consistent priority for operators. It is no longer allowed to write `a
and b or c` without parenthesis.
- Added and changed some operators (`date + duration` now allowed either way,
`int / int` now returns a decimal, added `duration / duration`)
- Added the ability to have variables and functions defined at
top-level (outside of any scope). See annex A of the tutorial for details.
- Added support for functions with multiple arguments
- Some big refactors in the compiler, allowing much better code sharing between
the different passes, and making it much easier to extend. Also added the
possibility to run the type-checker earlier, etc.
- Countless bug-fixes
- Improvements to our proof backend with Z3
- A tool to automatically synchronise with the upstream French law from
Legifrance
Fixes#378
- the plugins are compiled as libraries rather than with `executable`, so that
dune is able to install them
- they get installed to `lib/catala/plugins/<plugin-name>/<plugin-name>.cmxs`
- the lookup for plugins is now recursive to cope with the plugin subdirectories
in the point above
