DESCRIPTION

The init command initializes a project in one or more build configurations. The first form initializes the specified project packages (pkg-spec), or, if the project itself is specified (prj-spec), all its available packages, in one or more build configurations (cfg-spec) that have already been associated with the project (bdep-config(1)).

If no project directory is specified, then the current working directory is assumed. If no configuration is specified, then the default configuration is assumed (failing if multiple default configurations are present). See bdep-projects-configs(1) for details on specifying projects and configurations. Optional pkg-args are the additional dependency packages and/or configuration variables to pass to the underlying bpkg-pkg-build(1) command.

The second form (--empty is specified) initializes an empty project database that can later be used to first add build configurations (bdep-config(1)) and then initialize project packages using the first form.

The third (--config-add) and fourth (--config-create) forms are shortcuts to first adding an existing or newly created build configuration and then initializing project packages in that configuration. Semantically they are equivalent to first performing the config add or config create commands (bdep-config(1)), respectively, followed by the first form. Optional cfg-args in the fourth form are the additional arguments to the underlying bpkg-cfg-create(1) command. Note that in this case to specify pkg-args without specifying cfg-args you have to use two -- separators, for example:

$ bdep init -C ../prj-gcc @gcc -- -- ?sys:libsqlite3/*

Configuration variables can be specified to only apply to specific packages in pkg-args using the argument grouping mechanism (bdep-argument-grouping(1)). Additionally, such packages can be placed into specific linked configurations by specifying the configuration with one of the --config* options (or @ notation) using the same grouping mechanism. For example (assuming gcc is linked to common):

$ bdep init @gcc { @common config.liblarge.extra=true }+ ?liblarge

EXAMPLES

As an example, consider project prj with two packages, foo and libfoo:

prj/
|-- foo/
`-- libfoo/

The following invocations illustrate the common init use cases (the current working directory is shown before the shell prompt).

Create new build configuration in ../prj-gcc, call it gcc, and initialize project packages foo and libfoo in this configuration:

prj/$ bdep init -C ../prj-gcc @gcc cc config.cxx=g++

Create new build configuration in ../prj-clang using bpkg-cfg-create(1). Then add it calling it clang and initialize project package foo in this configuration:

prj/$ bpkg create -d ../prj-clang cc config.cxx=clang++
prj/$ cd foo
foo/$ bdep init -A ../../prj-clang @clang

Initialize project package libfoo in the build configuration clang:

foo/$ cd ..
prj/$ bdep init -d libfoo @clang

The following set of invocations achieves the same end result but using the bdep-config(1) command to manage configuration.

Initialize an empty project database:

prj/$ bdep init --empty

Create new build configuration in ../prj-gcc, call it gcc:

prj/$ bdep config create ../prj-gcc @gcc cc config.cxx=g++

Add existing build configuration in ../prj-clang, call it clang.

prj/$ bdep config add ../prj-clang @clang

Initialize project packages foo and libfoo in build configurations gcc and clang.

prj/$ bdep init @gcc @clang

Or, alternatively, in all the build configurations:

prj/$ bdep init -a

INIT OPTIONS

--empty|-E
    Initialize an empty build configuration set.

--config-add|-A dir
    Add an existing build configuration dir.

--config-create|-C dir
    Create a new build configuration in dir.

--no-sync
    Enter the project into the database but do not initialize it in the build configurations. The initialization can be finished later with an explicit bdep-sync(1) command.

--sys-no-query
    Do not query the system package manager for the installed versions of packages specified with the sys scheme. See the corresponding bpkg-pkg-build(1) option for details.

--sys-install
    Instruct the system package manager to install available versions of packages specified with the sys scheme that are not already installed. See the corresponding bpkg-pkg-build(1) option for details.

--sys-no-fetch
    Do not fetch the system package manager metadata before querying for available versions of packages specified with the sys scheme. See the corresponding bpkg-pkg-build(1) option for details.

--sys-no-stub
    Do no require a stub for packages specified with the sys scheme. See the corresponding bpkg-pkg-build(1) option for details.

--sys-yes
    Assume the answer to the system package manager prompts is yes. See the corresponding bpkg-pkg-build(1) option for details.

--sys-sudo prog
    The sudo program to use for system package manager interactions that normally require administrative privileges (fetch package metadata, install packages, etc). See the corresponding bpkg-pkg-build(1) option for details.

--create-host-config
    Create a configuration for build-time dependencies without prompt (see bdep-sync(1) for details).

--create-build2-config
    Create a configuration for build system module dependencies without prompt (see bdep-sync(1) for details).

--type|--config-type typ
    The type of the configuration being created. By default, configuration of type target is created. See bpkg-cfg-create(1) for background on configuration types.

--default
    Make the added or created configuration the default.

--no-default

--no-forward
    Don't make the added or created configuration forwarded.

--auto-sync
    Make the added or created configuration automatically synchronized.

--no-auto-sync
    Don't make the added or created configuration automatically synchronized.

--existing|-e
    Initialize a bpkg configuration based on an existing build system configuration.

--wipe
    Wipe the configuration directory clean before creating the new configuration.

--all|-a
    Use all build configurations.

--config|-c dir
    Specify the build configuration as a directory.

--directory|-d dir
    Assume project/package is in the specified directory rather than in the current working directory.

--config-name|-n name
    Specify the build configuration as a name.

--config-id num
    Specify the build configuration as an id.

DEFAULT OPTIONS FILES

See bdep-default-options-files(1) for an overview of the default options files. For the init command the search start directory is the project directory. The following options files are searched for in each directory and, if found, loaded in the order listed:

bdep.options
bdep-{config config-add}.options                # if --config-add|-A
bdep-{config config-add config-create}.options  # if --config-create|-C
bdep-init.options

The following init command options cannot be specified in the default options files:

--directory|-d
--config-add|-A
