1 Introduction

doplus - an iteration macro for Common Lisp

This is DO+ (doplus), the high-level, extensible iteration construct for Common Lisp.

By design, doplus has a reasonably simple implementation, that in particular doesn't make use of a code walker, allowing users to freely mix doplus loops with macrolets and every other kind of advanced Lisp construct.

Installation and dependencies

The preferred way to install doplus is by using Quicklisp.

doplus itself depends only on parse-declarations. FiveAM is used for the test suite.

Tests

To run the test suite, use ASDF.

License

doplus is distributed under the GPLv3. See the file COPYING for details. If you'd like a different license arrangement, please contact me. I'm very open about providing friendlier licenses to individuals and companies that I trust, but by default I won't allow complete strangers to profit from my code without giving anything back.

Further information

The home of doplus is https://bitbucket.org/alessiostalla/doplus. There you can find in-depth documentation, access the code repository and checkout the latest version.

Macro: being FORM &key THEN

Assigns to the iteration variable a value computed by evaluating FORM on each iteration, including the first. Optionally, the variable can be updated evaluating a differen form (the value of the ‘then’ parameter). Examples: (for x (being (random))), (for y (being ’quiet :then (if (> x 0.5) ’angry ’quiet))).

Macro: for VAR-OR-VARS ITERATION

General iteration clause. Its actual behaviour is controlled by ITERATION, a macro form that FOR expands with *ITERATION-VARIABLE* bound to VAR. Example: in (for x (in ’(1 2 3))), IN is a macro that expands into clauses that make use of *ITERATION-VARIABLE*, which is bound to the symbol X in the example. For certain iteration macros, VAR can be a lambda-list as well, in which case destructuring is applied. Example: (for (x &optional y) (in-list ’((1 2) (3)))).

Package

doplus

Source

doplus.lisp (file)

Macro: from INITIAL-VALUE &key TO BY WHILE USING

Iterates from a given initial value to an optional maximum. Every iteration increments/decrements the value applying the <using> function (by default +) to the previous value and <by> (by default 1 or -1, depending on whether to >= from or not). Similarly, the <while> function is used to determine if <to> has been reached or surpassed. <while> is a function of two arguments, the current value and the value of <to>, and as soon as it returns false, the loop is terminated. <while> defaults to a function that returns true only if <to> has been specified and, letting cur be the current value, (<= (min to from) cur (max to from)).

Package

doplus

doplus.lisp (file)

Macro: generating VAR ITERATION

Lazy version of FOR. The user must call UPDATE or TRY-UPDATE in the body of the DO+ form in order to compute new values for the variable(s). Initialization, instead, is *always* performed eagerly.

Package

doplus

Source

doplus.lisp (file)

Macro: hash-entries-of HASH-TABLE

Iterates over the entries of a hash table. The iteration variables must be specified as (key value), for example: (for (lemma definitions) (hash-entries-of the-english-vocabulary)).

Package

doplus

Source

doplus.lisp (file)

Macro: in SEQ &rest ARGS &key &allow-other-keys

Iterates over a sequence. IN must be used in combination with FOR, GENERATING and similar macros (those that bind *ITERATION-VARIABLE*). In implementations with extensible sequences (currently ABCL and SBCL), native sequence iterators are used, and all sequence types are supported, not just lists and vectors. In other implementations, an iterator specialized for lists or vectors is used depending on the type of sequence. All ‘args‘ are passed down to make-sequence-iterator (see the extensible sequences API paper for details [Rhodes2007]). IN can perform destructuring.

Package

doplus

Source

doplus.lisp (file)

Macro: in-list LIST &key BY REST

Like IN, but specialized for lists. Successive lists are obtained by calling the function BY (which by default is #’CDR) on the previous list. REST, if specified, is the variable holding the remaining elements to be processed; REST initially is bound to the entire list, then to successive lists obtained by funcalling BY.

Package

doplus

Source

doplus.lisp (file)

Macro: in-vector VECTOR &key INDEX START END BY

Loops across a vector. INDEX is bound to the index of the current element in the vector. The vector is traversed starting from index START (0 by default) to index END (the end of the vector if not specified); the index is incremented by BY (1 by default) on each iteration.

Macro: returning &rest FORMS

Returns each form in <forms> as the value of the do+ form when the loop ends. If multiple forms are specified, by one or more RETURNING clauses, multiple values are returned, in the order the corresponding forms appear lexically. If one of the <forms> is (cl:values ...), then each value will be returned as if the values were spelled as direct arguments of the RETURNING form.

Macro: terminate &optional LOOP-NAME RETURN-VALUE

Immediately terminates the loop. Refers to the current loop or, if loop-name is specified and non-NIL, to the closest surrounding loop with that name. Can optionally specify a return value for the loop, which, if provided, will override the loop’s ordinary return value.

Macro: to FINAL-VALUE &key FROM BY WHILE USING

Variation over from.

Package

doplus

Source

doplus.lisp (file)

Macro: try-update VAR &key ON-ERROR

Tries to update the generator named <var> as by UPDATE. If the loop would be terminated as a result of the update operation, it is not terminated.

Any errors occurring during the update are ignored by default; however, it is possible to provide a function to be invoked in case of error to determine what to do. This is the value of the <on-error> parameter, which, if provided, must be a function of two arguments: the first is the value to be returned as the result of the try-update form if the error is suppressed; the second is the condition object itself, which can be resignaled. Calling TERMINATE inside the function, if it is defined lexically inside the DO+ body, will regularly terminate the loop.

doplus

doplus.lisp (file)

Macro: update VAR

Updates the generator named <var>, calculating new value(s) for its variable(s) and evaluating its pre and post conditions, terminating the loop if they fail. If successful, the update returns the value of <var>.
