alr - Ada Library Repository
alr [global options] <command> [command options]] [<arguments>]
Alire is a source-based package manager for the Ada and SPARK programming languages.
It is a way for developers to easily build upon projects (libraries or programs) shared by the community, but also to easily share their projects for others to build upon.
In the Alire vocabulary, sources of projects/libraries/programs are provided by what is called a crate. A crate can depend on crates, and other crates can depend on it. For instance, the libgpr crate depends on the xmlada crate.
Crates can have multiple dependencies, themselves having multiple dependencies. This forms a dependency graph. Alire's main task is to automatically fetch, build and upgrade the crates of the dependency graph so you don't have to do it by hand.
The main interface into the Alire ecosystem is a command line tool called alr.
Command aliases can be defined in local or global configuration.
For example the following command: "$ alr config --set --global alias.graph 'show --graph'" Defines a global alias for the 'show' command with a --graph switch.
"$ alr graph" is equivalent to "alr show --graph"
Identifiers for crates and indexes must use lowercase alphanumeric characters from the latin alphabet. Underscores can also be used except as the first character.
Length must be of 3 to 64 characters.
Alire indexes binary releases of GNAT and gprbuild. The compilers are indexed with their target name, e.g., gnat_native or gnat_riscv_elf.
Use alr toolchain --help to obtain information about toolchain management. Alire can be configured to rely on a toolchain installed by the user in the environment, or to use one of the indexed toolchains whenever possible.
Some crates may override the default toolchain by specifying dependencies on particular compiler crates, for example to use a cross-compiler. In this situation, a compiler already available (selected as default or already installed) will take precedence over a compiler available in the catalog.
See also https://alire.ada.dev/docs/#toolchains for additional details about compiler dependencies and toolchain interactions.
