5.1.2 Macros

Macro: declare-goal NAME LAMBDA-LIST &body BODY

Declares the goal ‘name’. Before matching goals defined with
‘def-goal’ are executed, ‘body’ is executed with ‘pattern’ lexically
bound to the parameter specified when the goal was called. ‘body’ is
executed in an unnamed block that allows for suppressing the execution
of any goal. The idea behind that is that ‘body’ can verify if the
goal already holds and suppress execution of any code.

Package

cram-language-implementation

Source

goals (Lisp file)

Macro: def-cpl-parameter NAME &optional VAL DOC

Defines a global variable (like DEFPARAMETER) that is implemented as a
fluent. You can access it like a lisp variable with "NAME", and also setf it like a lisp variable "(SETF NAME)" - note there is no need for
"(VALUE NAME)". However the variable being implemented as a fluent means that the access is implicitely synchronized with a lock, and all changes are traced if fluent tracing is enabled.

You cannot directly access the implementing fluent which means that you cannot use it for building fluent nets or in cpl-constructs like
WHENEVER. (Just use a normal variable containing a fluent for those purposes).

You can use this for example for defining global datastructures that need not participate directly in cpl constructs, but should be traced in the execution trace and/or accessed by multiple tasks/threads simultaniously.

Package

cram-language-implementation

Source

value-fluent (Lisp file)

Macro: def-cram-function NAME LAMBDA-LIST &rest BODY

Defines a cram function. All functions that should appear in the
task-tree must be defined with def-cram-function.

CAVEAT: See docstring of def-top-level-cram-function.

Package

cram-language-implementation

Source

plans (Lisp file)

Macro: def-goal (NAME &rest PATTERN) &body BODY

Defines a new goal. Goals always have the form

(<name> [pattern]*)

where patterns can be arbitrary expressions containing
variables (indicated by a ?-prefix) and symbols.
Example: (achieve (loc ?obj ?location)) When defining goals with
similar expressions (e.g. (loc Robot ?l) and (loc ?a ?b)) the most
specific expression must be defined first. Otherwise, the previously
defined expression will be overwritten.

In the lexical environment of ‘body’, the function (SUCCEED [values])
is defined which performs a non-local exit, returning ‘values’ as
return values.

goals (Lisp file)

Macro: def-plan NAME LAMBDA-LIST &rest BODY

plans (Lisp file)

Macro: def-top-level-cram-function NAME ARGS &body BODY

Defines a top-level cram function. Every top-level function has its
own episode-knowledge and task-tree.

CAVEAT: Don’t have surrounding FLET / LABLES / MACROLET /
SYMBOL-MACROLET / LET / etc when using DEF-TOP-LEVEL-CRAM-FUNCTION
or DEF-CRAM-FUNCTION (unless you really know what you are
doing). They could mess with (WITH-TAGS ...) or shadow globally
defined plans, which would not be picked up by WITH-TAGS /
EXPAND-PLAN. See the comment before the definition of WITH-TAGS for
more details.

Macro: define-policy NAME PARAMETERS &rest PROPERTIES

This macro implicitly calls ‘make-policy’, and pushes the generated
policy onto the list of defined policies, thus making it accessible to ‘named-policy’ and ‘with-named-policy’ by its name. The usage is the
same as for ‘make-policy’:

> (define-policy policy-1 (param-1 param-2)
"The documentation string for this policy"
(:init (do-initialization-here))
(:check (do-checking-here))
(:recover (do-recovering-here))
(:clean-up (do-cleaning-up-here)))

Package

cram-language-implementation

Source

with-policy (Lisp file)

Macro: define-task-variable NAME &optional GLOBAL-VALUE DOCSTRING &key TYPE INIT-FUNCTION IGNORE-PACKAGE-LOCKS

Define a binding for ‘name’ as a special variable, and in
particular as a task variable.

‘global-value’ is the variable’s global value; if not given, the
variable is unbound. ‘docstring’ is its documentation string. ‘type’
is, optionally, its globally proclaimed type.

A task variable is a binding that is established and initialized right
before execution of a task. The binding is task-local, meaning that
assignment to it won’t affect the variable’s global binding, or
bindings within other tasks.

The initialization is performed by ‘init-function’ which must be a
function of three parameters: the TASK object going to be executed,
the TASK object of the parent task, and the previous value of ‘name’
in the parent. In case the task object is a TOPLEVEL-TASK, the second
argument will be NIL, and the third one will be the global value.

Task variables can hence be used for different purposes:

1. to initialize a variable based on the task object to be executed.

2. to initialize a variable based on the task’s parent.

3. to inherit a task variable’s value from its parent.

In case ‘init-function’ is not given, the default behaviour is the
behaviour of the 3rd item.

Package

cram-language-implementation

task-interface (Lisp file)

Macro: log-event &body CLAUSES

Logs an event specified by ‘clauses’ to *LOG-OUTPUT*.

Syntax:

clauses ::= (:CONTEXT fmt-ctrl . fmt-args)
| (:DISPLAY fmt-ctrl . fmt-args)
| (:TAGS tag+)

A log entry will look like

<realtime> , <runtime> - <current task> > <context> ; <display>

Where

<realtime> denotes a timestamp relative to *ZERO-REAL-TIME*,

<runtime> denotes a timestamp relative to *ZERO-RUN-TIME*,

<current task> denotes the name of the currently active task,

<context> denotes the result of the format-control ‘fmt-ctrl’ applied to the format-arguments ‘fmt-args’ of the
given :CONTEXT clause,

<display> ditto but for the :DISPLAY clause.

The :TAGS clause specifies the log tags that must be active for
this LOG-EVENT to emit any output.

It is hence possible to specify the degree of logging in a very fine-grained way: log tags can be dynamically enabled by
LOG-ENABLE, disabled by LOG-DISABLE, and set by LOG-SET.

Most defined log tags correspond to constructs of cpl or the underlying implementation. Use the :debug tag for adding (temporary) debug messages.

For convenience, the following constants are defined to enable a
bunch of tags at once:

+LOG-ALL+ - set of all available tags

+LOG-DEFAULT+ - a predefined default set

+LOG-VERBOSE+ - +LOG-DEFAULT+ + more

+LOG-VERY-VERBOSE+ - +LOG-VERBOSE+ + even more

+LOG-LANGUAGE+ - set of all CRAM language constructs.

Macro: make-policy NAME PARAMETERS &rest DOC-AND-PROPERTIES

Generates a policy based on the information supplied. ‘name’
specifies an internal name for the policy, to be used with
‘named-policy’, or ‘with-named-policy’. ‘parameters’ is a list of
parameter symbols to be used by code inside the policy. Every time, a
piece of code inside the policy is executed, these parameters (with
assigned values from the ‘with-policy’, or ‘with-named-policy’ call)
are passed to the code segments. The ‘properties’ variable holds a
list of labelled code segments for execution during certain phases. An
example would look like this:

> (make-policy policy-1 (param-1 param-2)
"The documentation string for this policy"
(:init (do-initialization-here))
(:check (do-checking-here))
(:recover (do-recovering-here))
(:clean-up (do-cleaning-up-here)))

This returns a policy object to be used with ‘with-policy’. For
further information about when each function block is executed, see ‘with-policy’. The semantics of the ‘properties’ variable are like
this:

- Forms given via ‘:init’ are executed exactly once, when the policy
is initialized for usage. In case this function returns ‘nil’,
execution of the ‘body’ code is not started, none of the other
policy code blocks are executed, and a failure of type
‘policy-init-failed’ is thrown.

- A function given under the label ‘:check’ is executed every time ‘with-policy’ checks if the policy condition is met or not. If this
function returns ‘t’, the condition is met, the ‘:recover’ function
block is executed, and the execution of both, the policy, and the
wrapped body code of ‘with-policy’ is stopped.

- Either when the policy (due to a met policy condition), or the
wrapped body of ‘with-policy’ code stopped execution of the current
code block, the ‘:clean-up’ function block is executed to perform
clean-up procedures.

Specify ordering constraints for ‘steps’. ‘steps’ are executed in

always has the form:

(:order <contstraining-task> <constrained-task>)

‘constraining-task’ and ‘constrained-task’ are task objects. That
means, they can be either be defined in the current lexical
environment (over a :tag) or by either using the function TASK to
reference the task by its absolute path or the function SUB-TASK to
reference it by its path relative to the PARTIAL-ORDER form.

Macro: replaceable-function NAME LAMBDA-LIST PARAMETERS PATH-PART &body BODY

Besides the replacement of simple code parts defined with ’with-task-tree-node’, it is necessary to also pass parameters to the replaceable code
parts. For that, replaceable functions can be defined. They are not
real functions, i.e. they do change any symbol-function or change
the lexical environment. ’name’ is used to mark such functions in
the code-sexp. More specifically, the sexp is built like follows: ‘(replaceable-function ,name ,lambda-list ,@body).
The ’parameters’ parameter contains the values to call the function with.

Macro: retry-after-suspension &body BODY

Execute ‘body’, and return its values.

In case a suspension event occurs during the execution, ‘body’ is completely unwound, and the suspension takes place _outside_ of
‘body’. After wakeup, ‘body’ is executed again.

The intended use case is to unwind out of critical sections to
ensure that a task won’t suspend while holding on locks.

Macro: with-failure-handling CLAUSES &body BODY

Macro that replaces handler-case in cram-language. This is
necessary because error handling does not work across multiple
threads. When an error is signaled, it is put into an envelope to
avoid invocation of the debugger multiple times. When handling errors,
this envelope must also be taken into account.

We also need a mechanism to retry since errors can be caused by plan
execution and the environment is highly non-deterministic. Therefore,
it is possible to use the function ‘retry’ that is lexically bound
within with-failure-handling and causes a re-execution of the body.

When an error is unhandled, it is passed up to the next failure

Macro: with-named-policies POLICIES-AND-PARAMETERS-LIST &body BODY

The semantics of ‘with-named-policies’ are the same as for ‘with-policies’, except that instead of policy-objects, policy names are used:

> (with-named-policies
((’my-policy (3 1))
(’my-policy (100 4))
(’my-other-policy ("Test")))

with-policy (Lisp file)

Macro: with-named-policy POLICY-NAME POLICY-PARAMETERS &body BODY

Performs the same as ‘with-policy’, but accepts a policy name
instead of the policy object itself. This calls an implicit
‘named-policy’ to acquire the policy object. Otherwise, it has the
same semantics as ‘with-policy’. Usage:

> (with-named-policy ’policy-name (param-value-1 param-value-2) (body-code))

Package

with-policy (Lisp file)

Macro: with-policies POLICIES-AND-PARAMETERS-LIST &body BODY

Allows for running a given ‘body’ code segment wrapped in a list of
policies (together with individual parameters for each of them). The ‘policies-and-parameters-list’ parameter describes a list of policy/parameter-list pairs.

The usage is as follows:

> (with-policies
((my-policy-object (3 1))
(my-policy-object (100 4))
(my-other-policy-object ("Test")))
(body-code))

Package

cram-language-implementation

Source

with-policy (Lisp file)

Macro: with-policy POLICY POLICY-PARAMETERS &body BODY

Wraps the code given as ‘body’ into a ‘pursue’ construct together
with monitoring code supplied by the policy ‘policy’, and given the
parameters ‘policy-parameters’. The ‘policy-parameters’ allow for
custom parameterization of policies. First, the policy is initialized
via the optional ‘:init’ code block. In case this block returns ‘nil’, execution of the ‘body’ code or other policy-related code blocks is
not started. An exception of type ‘policy-init-failed’ is
thrown. Otherwise, the ‘:check’ code block of the policy is executed
in a loop in parallel to the ‘body’ code. If the ‘:check’ code returns
‘t’, the policy condition is met and the ‘:recover’ code block is
executed. The execution of both, the policy, and the ‘body’ code is
the stopped, and the ‘:clean-up’ policy code is executed. If the
policy condition is never met, ‘body’ finishes and returns
normally.

To clarify the order of code execution here:

- Initialization of policy is executed (‘:init’)

- ‘pursue’ code form is started, with up to two forms inside:
- The policy ‘:check’ code block (if present)
- The ‘body’ code

- ‘:check’ is evaluated continuously, in parallel to the normal
execution of ‘body’. If it returns ‘nil’, nothing happens. In any
other case (i.e. return value is unequal to ‘nil’), the execution of
the ‘body’ code is interrupted, and ‘:check’ is not performed again
anymore. The policy code block given in ‘:recover’ is executed (if
present). This means (explicitly) that the ‘:recover’ code is
performed *after* the ‘body’ code got interrupted.

- If ‘:check’ always returns ‘nil’ until the ‘body’ code execution
finishes, ‘:recover’ is never executed.

- In either case (with or without ‘:recover’), the policy ‘:clean-up’
code is performed (if present).

In each of the phases, ‘policy-setf’ and ‘policy-get’ are
available. They can be used to store variables associated with given
symbols for the course of action of the current policy.

Example:

> (define-policy var-test-policy ()
"Variable Test Policy"
(:init (policy-setf ’some-var 10)
t)
(:check (policy-setf ’some-other-var
(+ (policy-get ’some-var) 2))
nil)
(:clean-up (format t "Variables: ~a ~a~%"
(policy-get ’some-var)
(policy-get ’some-other-var))))

Usage of ‘with-policy’:

> (with-policy policy-object (param-value-1 param-value-2)
(body-code))

Macro: with-retry-counters COUNTER-DEFINITIONS &body BODY

Lexically binds all counters in ‘counter-definitions’ to the intial
values specified in ‘counter-definitions’. ‘counter-definitions’ is
similar to ‘let’ forms with the difference that the counters will
not be available under the specified names in the lexical
environment established by this macro. In addition, the macro
defines the local macro (DO-RETRY <counter> <body-form>*) to
decrement the counter and execute code when the maximal retry count
hasn’t been reached yet and the function ‘(RESET-COUNTER
<counter>).

Function: fl-pulsed FLUENT &key HANDLE-MISSED-PULSES

Returns a fluent whose value becomes T only and only if its parent
fluent has been pulsed. How long it stays T depends on the parameter ‘handle-missed-pulses’. It can be either :NEVER :ONCE or :ALWAYS:

- :NEVER means that missed pulses are ignored, i.e. the initial
value is always NIL and becomes T only when ‘fluent’ gets
pulsed. It stays T only for exactly one call of VALUE, even if
more than one pulse occured since the last call to VALUE.

- :ONCE is similar to :NEVER but has an initial value of T if
‘fluent’ has been pulsed at least once before.

- :ALWAYS means that the VALUE method returns T for exactly the
number of pulses of ‘fluent’.

Please note that the value of a PULSE-FLUENT changes from one call to
another. That means it is not re-entrant, and FL-PULSED should not be
bound to a variable or passed around. This could lead to unwanted
behavior if one thread catches pulses another one was to handle.

5.2.2 Macros

Macro: def-fluent-operator &whole W NAME ARGS &body BODY

def-fluent-operator allows to define fluent operators. It creates a
new function with the given name. When it is called with a fluent
in its parameter list, a fluent network is returned, with the
function body as its calculator. Otherwise, the body is called
directly.

We need one special case. Some operators need to always pulse the
returned fluent net. This is solved by havin a second value. When
the body returns a non-nil second value, the fluent net is always
pulsed, otherwise only when the fluent net value has changed.

Package

cram-language-implementation

Source

fluent-net (Lisp file)

Macro: def-plan-macro NAME LAMBDA-LIST &body BODY

Wrapper around DEFMACRO for defining macros constituting cpl constructs
used in plans.

DEF-PLAN-MACRO wraps ‘body’ in code that checks that it is only used within cpl plans. More precicesly the macro includes a check that it is used in a dynamic context where *CURRENT-TASK* is not nil. Otherwise an ERROR condition is signaled (at runtime).

DEF-PLAN-MACRO also adds information about the plan macro (‘lambda-list’ and ‘body’) to the symbol ‘name’, so the plan walker can use this information during plan expansion. This information can also be used for plan transformation.

Macro: with-parallel-childs NAME (RUNNING DONE FAILED) CHILD-FORMS &body WATCHER-BODY

Execute ‘child-forms’ in parallel and execute ‘watcher-body’
whenever any child changes its status.

Lexical bindings are established for ‘running’, ‘done’ and ‘failed’
around ‘watcher-body’, and bound to lists of all running, done and
failed tasks. ‘watcher-body’ is executed within an implicit block
named NIL.

‘name’ is supposed to be the name of the plan-macro that’s
implemented on top of WITH-PARALLEL-CHILDS. ‘name’ will be used to
name the tasks spawned for ‘child-forms’.

All spawned child tasks will be terminated on leave.
