Introduction The deoxybyte-io system is a selection of utility code focused on transfer of data between Lisp and its environment. It includes: - IO and parser conditions - File and directory utilities - Command line interface definition utilities - Stream classes and methods - Tabular text parsing - Binary encoding and decoding * * Nathan Froyd has released nibbles (https://github.com/froydnj/nibbles) which implements octet-vector operations similar to those in this system, only optimized for efficiency. I'll consider replacing my implementations with a shim to nibbles, or calling nibbles directly. Installation deoxybyte-io uses ASDF for system definition. Install as described in the ASDF documentation and then load: (asdf:load-system :deoxybyte-io) Alternatively, use the equivalent deoxybyte-systems:load-system function: (dxs:load-system :deoxybyte-io) Tests To run the unit and regression tests you need to have LIFT installed. Run the tests: (asdf:test-system :deoxybyte-io) Alternatively, use the equivalent deoxybyte-systems:test-system function: (dxs:test-system :deoxybyte-io) Documentation See the Lisp docstrings, particularly the package docstrings for an overview. HTML documentation may be generated with the command: (dxs:document-system :deoxybyte-io) at the REPL, provided that CLDOC is installed.

{define-condition malformed-field-error} is raised. The default error
message may be refined with an additional ERROR-MESSAGE.

an error is raised.

Rest:
- message-arguments (forms): Forms that evaluate to arguments for the error message.

{define-condition malformed-record-error} is raised. The default error
message may be refined with an additional ERROR-MESSAGE.
Arguments:

an error is raised.
- record (form): A form that evaluates to a record.
Optional:
- error-message (string): An error message string.

- option-name (string)
Rest:
- cl-option instance initargs
Key:
- documentation (string): Slot (and hence cli-option) documentation.
e.g.

command-line-interface.lisp (file)
Defines a function NAME with one mandatory argument, a simple-array
of unsigned-byte 8, and one optional argument, a fixnum index in that
array that defaults to 0. The function returns the Lisp integer whose
value is given by the bytes at that index in the byte array.
Key:
- bytes (fixnum): the number of bytes that comprise the number.
- order (sumbol): the byte order of the array, may be one
of :little-endian or :big-endian ( :network-byte-order may be used
as a synonym for :big-endian ).
- signed (boolean): T if the bytes are a two’s complement
representation of a signed integer.
binary-operations.lisp (file)
Defines a function NAME with two mandatory arguments, an integer
and a simple-array of unsigned-byte 8, and one optional argument, a
fixnum index in that array that defaults to 0. The function returns
the buffer containing the encoded integer.
Key:
- bytes (fixnum): the number of bytes that comprise the number.
- order (sumbol): the byte order of the array, may be one
of :little-endian or :big-endian ( :network-byte-order may be used
as a synonym for :big-endian ).
binary-operations.lisp (file)
Defines a line parser function that splits lines and then parses and
validates fields according to the FIELDS contraints and validates
combinations of fields according to CONSTRAINTS.
Arguments:
- parser-name (symbol): a symbol naming the new function.
- delimiter (character): a character used to split the lines being
parsed.
- fields (list list): a list of field definition lists. The form of a
definition list is
;;; (symbolic-field-name &keys type ignore parser validator null-str)
which indicates the symbol to which the parsed field value will be
stored in the alist returned by the function
- parser-name (symbol): the expected type of the field value ( :string,
:integer or :float, defaulting to :string), an optional boolean flag
indicating that the field should be ignored, an optional parser
function (defaults to a pass-through string parser), an optional
validator function that returns T when the parsed field is valid and
an optional string to indicate an null field (defaults to
{defparameter *empty-field*} ).
Optional:
- constraints (list list): a list of field constraint definition
lists. The form of a constraint definition list is
;;; (symbolic-constraint-name (symbolic-field-name list) validator)
The symbolic-field-name list should contain names of one or more fields and the validator must then be a function which accepts the parsed values of those fields in the same order and returns T when those fields have acceptable values.

TYPE may be used to specify the type of the new pathname, otherwise the original type will be used.

Returns a function of zero arity that generates pathnames when called. The generated pathnames are relative to DIRECTORY and have a namestring composed of NAME, SEPARATOR (defaults to NIL) and a value taken from calling the function GENERATOR (defaults to a numeric generator starting from 0, incrementing by 1). TYPE may be used to specify the type of the new pathnames.

files-and-directories.lisp (file)
sbcl.lisp (file)
sbcl.lisp (file)
Returns T if PATHSPEC is a pathname designator for a relative file or directory, or NIL otherwise.
files-and-directories.lisp (file)
Returns a pathname suitable for use as a temporary file or directory. The directory component of the new pathname is TMPDIR, defaulting to *DEFAULT-TMPDIR*. The NAME component of the new pathname is a concatenation of BASENAME, defaulting to an empty string, and a pseudo-random number. The type component of the new pathname is TYPE, defaulting to NIL.
files-and-directories.lisp (file)
Next: Exported conditions, Previous: Exported functions, Up: Exported definitions [Contents][Index]
Returns T if OPTION does not require a value, or NIL otherwise.

defaults to *ERROR-OUTPUT*). This is usually the class documentation
string of CLI, plus all of the option help.
command-line-interface.lisp (file)

CL:SORT, a function of two arguments that returns a generalized
boolean.
Key:
- key (function designator): A function of one argument, or nil.
- buffer-size (fixnum): The size of the in-memory sort buffer and
hence the number of elements written to disk in the external merge
file.

Returns a new {defclass merge-stream} appropriate
to SORT-INPUT-STREAM. The new stream must return sorted elements read
from SORT-INPUT-STREAM.
Arguments:

to be sorted.
- predicate (function designator): The sorting predicate, as in
CL:SORT, a function of two arguments that returns a generalized
boolean.
Key:
- key (function designator): A function of one argument, or nil.
- buffer-size (fixnum): The size of the in-memory sort buffer and
hence the number of elements written to disk in the external merge
file.

command-line-interface.lisp (file)
Returns the CLI option identified by NAME.
command-line-interface.lisp (file)
Returns T if SLOT is an option slot in CLI, or NIL
otherwise. The default implementation returns T, meaning that all
slots are expected to contain option objects. Overriding this method
means that slots may be added for other purposes.

Returns a new, sorted list of CLI option slots.
command-line-interface.lisp (file)
Returns a new, sorted list of CLI options.
command-line-interface.lisp (file)

accepted for an argument e.g. ’integer-list , they must be
comma-separated on the command line e.g. 1,2,3,4.
Arguments:
- cli (object): A CLI instance.
- arglist (list string): A list of CLI string arguments.
Returns:

Next: Internal functions, Previous: Internal special variables, Up: Internal definitions [Contents][Index]
Defines a function NAME with one mandatory argument, a simple-array
of unsigned-byte 8, and one optional argument, a fixnum index in that
array that defaults to 0. The function returns the Lisp float whose
value is given by the bytes at that index in the byte array.
Key:
- bytes (fixnum): the number of bytes that comprise the number.
- order (sumbol): the byte order of the array, may be one
of :little-endian or :big-endian ( :network-byte-order may be used
as a synonym for :big-endian ).
binary-operations.lisp (file)
Defines a function NAME with two mandatory arguments, a float and a
simple-array of unsigned-byte 8, and one optional argument, a fixnum
index in that array that defaults to 0. The function returns the
buffer containing the encoded float.
Key:
- bytes (fixnum): the number of bytes that comprise the number.
