6 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

6.1 Exported definitions

6.1.1 Special variables

Special Variable: *quasi-quote-lexical-depth*

The absolute level of read-time (lexical) nesting of the quasi-quote readers. It does not decrease at unquotes.

Package

hu.dwim.syntax-sugar

Source

quasi-quote.lisp (file)

Special Variable: *quasi-quote-nesting-level*

The read-time (lexical) nesting level of the quasi-quote readers, decreases when going through unquotes.

Package

hu.dwim.syntax-sugar

Source

quasi-quote.lisp (file)

Special Variable: *toplevel-readtable*

This is bound to the toplevel *readtable* by all the readers in hu.dwim.syntax-sugar. This is useful for example to restore the original readtable-case at random point in the nested readers.

Package

hu.dwim.syntax-sugar

Source

syntax-sugar.lisp (file)

6.1.2 Macros

Macro: define-syntax NAME ARGS &body BODY

Package

hu.dwim.syntax-sugar

Source

syntax-sugar.lisp (file)

Macro: enable-case-preserving-syntax &key (START-CHARACTER START-CHARACTER) (DISPATCH-CHARACTER DISPATCH-CHARACTER) (READTABLE-CASE READTABLE-CASE) (PACKAGES PACKAGES)

Package

hu.dwim.syntax-sugar

Source

case-preserving.lisp (file)

Macro: enable-feature-cond-syntax &key (START-CHARACTER START-CHARACTER) (DISPATCH-CHARACTER DISPATCH-CHARACTER) (END-CHARACTER END-CHARACTER) (READTABLE-CASE READTABLE-CASE)

Just like CL:COND but at read-time, and in the current package (as opposed to the keyword package as with #+/-).

Package

hu.dwim.syntax-sugar

Source

feature-cond.lisp (file)

Macro: enable-quasi-quote-syntax QUASI-QUOTE-WRAPPER UNQUOTE-WRAPPER &key (NESTED-QUASI-QUOTE-WRAPPER NESTED-QUASI-QUOTE-WRAPPER) (START-CHARACTER START-CHARACTER) (DISPATCH-CHARACTER DISPATCH-CHARACTER) (END-CHARACTER END-CHARACTER) (UNQUOTE-CHARACTER UNQUOTE-CHARACTER) (SPLICE-CHARACTER SPLICE-CHARACTER) (DESTRUCTIVE-SPLICE-CHARACTER DESTRUCTIVE-SPLICE-CHARACTER) (DISPATCHED-QUASI-QUOTE-NAME DISPATCHED-QUASI-QUOTE-NAME) (TOPLEVEL-READER-WRAPPER TOPLEVEL-READER-WRAPPER) (UNQUOTE-READTABLE-CASE UNQUOTE-READTABLE-CASE) (BODY-READER BODY-READER) (READTABLE-CASE READTABLE-CASE)

Package

hu.dwim.syntax-sugar

Source

quasi-quote.lisp (file)

Macro: enable-readtime-wrapper-syntax &optional START-CHARACTER END-CHARACTER

A utility read macro for modifying the read table.

The syntax is:

{SPECIFIER ...}

Where SPECIFIER is either a symbol naming a function (available at read time) or a list (SPECIFIER &rest ARGUMENTS). SPECIFIER is applied to ARGUMENTS to produce a function, this is then called and passed another function which reads until the #} character. During the executen of the function *readtable* is bound to a copy of the current read table.

Package

hu.dwim.syntax-sugar

Source

readtime-wrapper.lisp (file)

Macro: enable-sharp-boolean-syntax ()

This syntax reads "#t" as COMMON-LISP:T and "#f" as COMMON-LISP:NIL

Package

hu.dwim.syntax-sugar

Source

one-liners.lisp (file)

Macro: enable-sharp-comment-syntax ()

This syntax allows "#;" to be used to uncomment a whole sexp.

Package

hu.dwim.syntax-sugar

Source

one-liners.lisp (file)

Macro: enable-sharp-number-syntax ()

Package

hu.dwim.syntax-sugar

Source

number.lisp (file)

Macro: enable-string-quote-syntax &key (START-CHARACTER START-CHARACTER) (END-CHARACTER END-CHARACTER) (TRANSFORMER TRANSFORMER)

A simple string quote that unconditionally reads all characters until END-CHARACTER into a string.

Package

hu.dwim.syntax-sugar

Source

string-quote.lisp (file)

Macro: with-local-readtable &body BODY

Rebind a copy of *readtable*.

Package

hu.dwim.syntax-sugar

Source

syntax-sugar.lisp (file)

Macro: with-standard-readtable &body BODY

Rebind a copy of the standard *readtable*.

Package

hu.dwim.syntax-sugar

Source

syntax-sugar.lisp (file)

6.1.3 Functions

Function: get-macro-character* CHAR &optional READTABLE

Just like CL:GET-MACRO-CHARACTER but its second value defaults to T even if there’s no macro fn installed on CHAR.

Package

hu.dwim.syntax-sugar

Source

one-liners.lisp (file)

Function: list-readers &optional *READTABLE*

A very slow utility for REPL use.

Function: with-package PACKAGE-NAME

Package

hu.dwim.syntax-sugar

Source

quasi-quote.lisp (file)

Function: with-readtable-case CASE

When used as a specifier for the READTIME-WRAPPER syntax, it changes the readtable-case while reading its body. Behaves as an implicit progn.

Example: {(with-readtable-case :preserve) ’fOo} => |fOo|
