query
These are the flags/commands under buck2 query and their --help output:
Alias for `uquery`
Usage: buck2-release query [OPTIONS] <QUERY> [QUERY_ARGS]...
Arguments:
<QUERY>
the query to evaluate
[QUERY_ARGS]...
list of literals for a multi-query (one containing `%s` or `%Ss`)
Options:
-A, --output-all-attributes
Output all attributes, equivalent of --output-attribute ''.
Avoid using this flag in automation because it may be expensive to produce certain
attributes, and because it makes harder to track which special attributes are used.
-B, --output-basic-attributes
Output basic attributes, namely those the user can supply, plus rule type and package name
-a, --output-attribute <ATTRIBUTE>
Regular expressions to match attributes. Regular expressions are used in "search" mode, so
for example empty string matches all attributes including special attributes.
When using in automation, please specify the regular expression to match the attribute
precisely, for example `--output-attribute '^headers$'` to make it easier to track which
special attributes are used.
--output-attributes <ATTRIBUTE>...
Deprecated: Use `--output-attribute` instead.
List of space-separated attributes to output, --output-attributes attr1 attr2.
--json
Output in JSON format
--dot
Output in Graphviz Dot format
--dot-compact
Output in a more compact format than Graphviz Dot
--output-format <dot|dot_compact|json|starlark>
Output format (default: list).
dot - dot graph format.
dot_compact - compact alternative to dot format.
json - JSON format.
starlark - targets are printed like starlark code that would produce them.
[possible values: dot, json, dot_compact, starlark]
--modifier <VALUE>
This option is not used
-h, --help
Print help (see a summary with '-h')
Buckconfig Options:
-c, --config <SECTION.OPTION=VALUE>
List of config options
--config-file <PATH>
List of config file paths
--fake-host <HOST>
[possible values: default, linux, macos, windows]
--fake-arch <ARCH>
[possible values: default, aarch64, x8664]
--fake-xcode-version <VERSION-BUILD>
Value must be formatted as: version-build (e.g., 14.3.0-14C18 or 14.1-14B47b)
--reuse-current-config
Re-uses any `--config` values (inline or via modefiles) if there's a previous command,
otherwise the flag is ignored.
If there is a previous command and `--reuse-current-config` is set, then the old config is
used, ignoring any overrides.
If there is no previous command but the flag was set, then the flag is ignored, the
command behaves as if the flag was not set at all.
--exit-when-different-state
Used for exiting a concurrent command when a different state is detected
--preemptible <PREEMPTIBLE>
Used to configure when this command could be preempted by another command for the same
isolation dir.
Normally, when you run two commands - from different terminals, say - buck2 will attempt
to run them in parallel. However, if the two commands are based on different state, that
is they either have different configs or different filesystem states, buck2 cannot run
them in parallel. The default behavior in this case is to block the second command until
the first completes.
Possible values:
- never: (default) When another command starts that cannot run in parallel with
this one, block that command
- always: When another command starts, interrupt this command, *even if they
could run in parallel*. There is no good reason to use this other than that it provides
slightly nicer superconsole output
- ondifferentstate: When another command starts that cannot run in parallel with this one,
interrupt this command
Starlark Options:
--disable-starlark-types
Disable runtime type checking in Starlark interpreter.
This option is not stable, and can be used only locally to diagnose evaluation performance
problems.
--stack
Record or show target call stacks.
Starlark call stacks will be included in duplicate targets error.
If a command outputs targets (like `targets` command), starlark call stacks will be
printed after the targets.
Console Options:
--console <super|simple|...>
Which console to use for this command
[env: BUCK_CONSOLE=]
[default: auto]
[possible values: auto, none, simple, simplenotty, simpletty, super]
--ui <UI>...
Configure additional superconsole ui components.
Accepts a comma-separated list of superconsole components to add. Possible values are:
dice - shows information about evaluated dice nodes debugevents - shows information about
the flow of events from buckd
These components can be turned on/off interactively. Press 'h' for help when superconsole
is active.
Possible values:
- dice
- debugevents
- io: I/O panel
- re: RE panel
--no-interactive-console
Disable console interactions
[env: BUCK_NO_INTERACTIVE_CONSOLE=]
Event Log Options:
--event-log <PATH>
Write events to this log file
--write-build-id <PATH>
Write command invocation id into this file
--unstable-write-invocation-record <PATH>
Write the invocation record (as JSON) to this path. No guarantees whatsoever are made
regarding the stability of the format
--command-report-path <PATH>
Write the command report to this path. A command report is always written to
`buck-out/v2/<uuid>/command_report` even without this flag
Universal Options:
-v, --verbose <VERBOSITY>
How verbose buck should be while logging.
Values: 0 = Quiet, errors only; 1 = Show status. Default; 2 = more info about errors; 3 =
more info about everything; 4 = more info about everything + stderr;
It can be combined with specific log items (stderr, full_failed_command, commands,
actions, status, stats, success) to fine-tune the verbosity of the log. Example usage
"-v=1,stderr"
[default: 1]
--oncall <ONCALL>
The oncall executing this command
--client-metadata <CLIENT_METADATA>
Metadata key-value pairs to inject into Buck2's logging. Client metadata must be of the
form `key=value`, where `key` is a snake_case identifier, and will be sent to backend
datasets
