Commands

This page contains documentation for each BuildStream command, along with their possible options and arguments. Each command can be invoked on the command line, where, in most cases, this will be from the project’s main directory.

Most of the main options override options in the user preferences configuration file.

bst fetch

Fetch sources required to build the pipeline

By default this will only try to fetch sources which are required for the build plan of the specified target element, omitting sources for any elements which are already built and available in the artifact cache.

Specify –deps to control which sources to fetch:

none: No dependencies, just the element itself

Allow tracking to cross junction boundaries

Arguments

Optional argument(s)

bst track

Consults the specified tracking branches for new versions available to build and updates the project with any newly available references.

By default this will track just the specified element, but you can also update a whole tree of dependencies in one go.

none: No dependencies, just the specified elements
all: All dependencies of all specified elements
bst track [OPTIONS] [ELEMENTS]...

Options

--except <except_>

Arguments

ELEMENTS

Optional argument(s)

bst pull

Pull a built artifact from the configured remote artifact cache.

By default the artifact will be pulled one of the configured caches if possible, following the usual priority order. If the –remote flag is given, only the specified cache will be queried.

Specify –deps to control which artifacts to pull:

none: No dependencies, just the element itself
all: All dependencies
bst pull [OPTIONS] [ELEMENTS]...

Options

-d, --deps <deps>

The dependency artifacts to pull (default: none)

Options:none|all
-r, --remote <remote>

The URL of the remote cache (defaults to the first configured cache)

Arguments

ELEMENTS

Optional argument(s)

bst push

Push a built artifact to a remote artifact cache.

The default destination is the highest priority configured cache. You can override this by passing a different cache URL with the –remote flag.

Specify –deps to control which artifacts to push:

none: No dependencies, just the element itself
all: All dependencies
bst push [OPTIONS] [ELEMENTS]...

Options

-d, --deps <deps>

The dependencies to push (default: none)

Options:none|all
-r, --remote <remote>

The URL of the remote cache (defaults to the first configured cache)

Arguments

ELEMENTS

Optional argument(s)

bst show

Show elements in the pipeline

By default this will show all of the dependencies of the specified target element.

Specify –deps to control which elements to show:

none: No dependencies, just the element itself
plan: Dependencies required for a build plan
run: Runtime dependencies, including the element itself
build: Build time dependencies, excluding the element itself
all: All dependencies
FORMAT
~~~~~~
The –format option controls what should be printed for each element,
the following symbols can be used in the format string:
%{name} The element name
%{key} The abbreviated cache key (if all sources are consistent)
%{full-key} The full cache key (if all sources are consistent)
%{state} cached, buildable, waiting or inconsistent
%{config} The element configuration
%{vars} Variable configuration
%{env} Environment settings
%{public} Public domain data
%{workspaced} If the element is workspaced
%{workspace-dirs} A list of workspace directories

The value of the %{symbol} without the leading ‘%’ character is understood as a pythonic formatting string, so python formatting features apply, examle:

bst show target.bst –format
‘Name: %{name: ^20} Key: %{key: ^8} State: %{state}’

If you want to use a newline in a format string in bash, use the ‘$’ modifier:

bst show target.bst –format
$’———- %{name} ———-n%{vars}’
bst show [OPTIONS] [ELEMENTS]...

Options

--except <except_>

Except certain dependencies

-d, --deps <deps>

The dependencies to show (default: all)

Options:none|plan|run|build|all
--order <order>

Staging or alphabetic ordering of dependencies

Options:stage|alpha
-f, --format <format_>

Format string for each element

Arguments

ELEMENTS

Optional argument(s)

bst shell

Run a command in the target element’s sandbox environment

This will stage a temporary sysroot for running the target element, assuming it has already been built and all required artifacts are in the local cache.

Use the –build option to create a temporary sysroot for building the element instead.

Use the –sysroot option with an existing failed build directory or with a checkout of the given target, in order to use a specific sysroot.

If no COMMAND is specified, the default is to attempt to run an interactive shell.
