* Follow updated MSYS2 first install instructions

* Show proper error message if msys2 update fails

* Fix the command to query for pending updates

* Don't scare-warn needlessly during msys2 update

* Bump version to 1.2.2

Co-authored-by: Fabien Chouteau <Fabien-Chouteau@users.noreply.github.com>

* Fix crate config conflicts errors (#1208)

* Alire.Properties.Configurations: print boolean values in lowercase

To match casing of TOML files where they come from.

* Alire.Crate_Configuration: fix, improve, and test value conflicts

 - TOML value comparison was incorrect (use Equals function now)
 - The "set by" info was incorrect
 - Error message now show the conflicting values

* Set macOS version to 10.15 for CI

To avoid compiler issue with Xcode 14.

* Add support for FreeBSD (#22)

* update GNAT project to recognize -XOS=freebsd and configure accordingly
* add FreeBSD as a valid operating system
* add AMD64 as an alias for X86_64 because uname -m returns amd64 on FreeBSD
* add platform specific implementation for FreeBSD

To build on FreeBSD, we should use

gprbuild -j0 -P alr_env -XOS=freebsd

* Fixes requested during code review

* Fix logic and output to test log instead of stdout

Ignore package name casing and fix regular expression

Co-authored-by: GHA <actions@github.com>

This is a workaround for issue AdaCore/gnatstudio#128 and AdaCore/gnatcoll-core#64 where GNAT Studio fails to open recently-updated or newly-created alire files. Breaking the Ada_Compiler_Switches up into two statements resloves this problem.

* Honor the --force option when publishing a crate (#1083)

When publishing and checking for existing crate with same version,
if the crate already exist and the force option is used,
emit a warning message and continue.

* Use Recoverable_Error to report that a crate version already exists

Also this allows compilation with GNAT^12

* Replace buggy relative path in GNATCOLL
* New test for relative pins to parent crate

We were appending which could cause mix-ups when there was another compiler in
the user path (as we are already prepending in the case of PATH)

Co-authored-by: GHA <actions@github.com>

To differentiate from the published 1.2.0, since we have several backported PRs
from master in this branch already.

* Fix warnings in gnatcoll-slim

* Fix new warnings unearthed by GNAT 12.1

* Alire.Utils: add a function to return a string image of keys in map

* Alire.Expressions: improve error message with list of possible case

* Alire.TOML_Load: add missing host arch enum

With the current style checks it is easy to break coding style by having
to many values in an enum for instance.

In theory we could generate better code for enums. But since users can
use their own coding style, it is impossible to be compatible with in
every situation.

So the best option is to disable all checks for this file.

* Alr.Commands.Edit: update pointer to GNAT Studio release

* Update test.py

* Update user-changes.md

* Update user-changes.md

* Speed-up detection of installed externals in RPM distros

Although the yum/dnf wrappers are needed for the installation proper, we can
speed up detections of already installed packages by using rpm directly.
Unfortunately, rpm cannot give info on not installed packages, but this still
speeds up things greatly for the usual case of gnat/gprbuild being installed.

* Refactor duplicated code

* Fix early parsing of verbosity switches

We were recognizing them even after the subcommand. This also meant that it
would have been impossible to have regular output if a -v is intended for the
subcommand, e.g. in `alr exec -- whatever -v`.

* Bump/sync clic submodule/dependency

This switch was always added to the init crates and should have been
included in the first version of build profiles. The warnings are only
displayed for embedded project based on run-times without exception
propagation, and can be very annoying.

* Fix retrieval of git root and prefix inside repo

* Fix instantiation on older compilers

* Alire.VSSs.Git: Fix unreferenced parameter

* Alire.Publish: fix reversed logic

* Code review fixes

* Add a new --version standalone switch

* Add a couple of new tests

* Alire.Index_On_Disk: Drop index cache after deletion

Also ensure that all index addition functions operate with fresh index
information

* Bump index version

* Allow disabling the "old compatible index" warning

Also use real old compatible version to not have to use a fake old compatible version

* Make index set its own type

* Basics for individual crate loading in place

* Complete single crate loading and use in `show`

* Use Empty_Set instead of Empty for older compilers

Note that gprinstall won't complain if this folder doesn't exists, so
users can decided to leave it empty or remove it in case they don't have
resources.
