ex: the following rule is marked as a build setting by setting the build_setting
parameter of the rule()
function. Specifically it is a build setting of type int
and is a flag
which means this build setting is callable on the command line.
my_rule = rule( implementation = _impl, build_setting = config.int(flag = True), ... )
Members
bool
BuildSetting config.bool(flag=False)
Parameters
Parameter | Description |
---|---|
flag
|
bool;
default is False Whether or not this build setting is callable on the command line. |
exec
ExecTransitionFactory config.exec(exec_group=None)
Parameters
Parameter | Description |
---|---|
exec_group
|
string; or None ;
default is None The name of the exec group whose execution platform this transition will use. If not provided, this exec transition will use the target's default execution platform. |
int
BuildSetting config.int(flag=False)
Parameters
Parameter | Description |
---|---|
flag
|
bool;
default is False Whether or not this build setting is callable on the command line. |
string
BuildSetting config.string(flag=False, allow_multiple=False)
Parameters
Parameter | Description |
---|---|
flag
|
bool;
default is False Whether or not this build setting is callable on the command line. |
allow_multiple
|
bool;
default is False Deprecated, use a string_list setting with repeatable = True instead. If set, this flag is allowed to be set multiple times on the command line. The Value of the flag as accessed in transitions and build setting implementation function will be a list of strings. Insertion order and repeated values are both maintained. This list can be post-processed in the build setting implementation function if different behavior is desired.

string_list
BuildSetting config.string_list(flag=False, repeatable=False)
--//my/setting=foo,bar
.
Parameters
Parameter | Description |
---|---|
flag
|
bool;
default is False Whether or not this build setting is callable on the command line. |
repeatable
|
bool;
default is False If set, instead of expecting a comma-separated value, this flag is allowed to be set multiple times on the command line with each individual value treated as a single string to add to the list value. Insertion order and repeated values are both maintained. This list can be post-processed in the build setting implementation function if different behavior is desired. |
target
transition config.target()
cfg = "target"
