+1 macrostep: interactive macro-expander
+═══════════════════════════════════════
+
+ `macrostep' is an Emacs minor mode for interactively stepping through
+ the expansion of macros in Emacs Lisp source code. It lets you see
+ exactly what happens at each step of the expansion process by
+ pretty-printing the expanded forms inline in the source buffer, which
+ is temporarily read-only while macro expansions are visible. You can
+ expand and collapse macro forms one step at a time, and evaluate or
+ instrument the expansions for debugging with Edebug as normal (but see
+ "Bugs and known limitations", below). Single-stepping through the
+ expansion is particularly useful for debugging macros that expand into
+ another macro form. These can be difficult to debug with Emacs'
+ built-in `macroexpand', which continues expansion until the top-level
+ form is no longer a macro call.
+
+ Both globally-visible macros as defined by `defmacro' and local macros
+ bound by `(cl-)macrolet' or another macro-defining form can be
+ expanded. Within macro expansions, calls to macros and compiler
+ macros are fontified specially: macro forms using
+ `macrostep-macro-face', and functions with compiler macros using
+ `macrostep-compiler-macro-face'. Uninterned symbols (gensyms) are
+ fontified based on which step in the expansion created them, to
+ distinguish them both from normal symbols and from other gensyms with
+ the same print name.
+
+ As of version 0.9, it is also possible to extend `macrostep' to work
+ with other languages with macro systems in addition to Emacs Lisp. An
+ extension for Common Lisp (via SLIME) is in the works; contributions
+ for other languages are welcome. See "Extending macrostep" below for
+ details.
+
+
+1.1 Key-bindings and usage
+──────────────────────────
+
+ The standard keybindings in `macrostep-mode' are the following:
+
+ e, =, RET
+ expand the macro form following point one step
+ c, u, DEL
+ collapse the form following point
+ q, C-c C-c
+ collapse all expanded forms and exit macrostep-mode
+ n, TAB
+ jump to the next macro form in the expansion
+ p, M-TAB
+ jump to the previous macro form in the expansion
+
+ It's not very useful to enable and disable macrostep-mode directly.
+ Instead, bind `macrostep-expand' to a key in `emacs-lisp-mode-map',
+ for example C-c e:
+
+ ┌────
+ │ (define-key emacs-lisp-mode-map (kbd "C-c e") 'macrostep-expand)
+ └────
+
+ You can then enter macrostep-mode and expand a macro form completely
+ by typing `C-c e e e ...' as many times as necessary.
+
+ Exit macrostep-mode by typing `q' or `C-c C-c', or by successively
+ typing `c' to collapse all surrounding expansions.
+
+
+1.2 Customization options
+─────────────────────────
+
+ Type `M-x customize-group RET macrostep RET' to customize options and
+ faces.
+
+ To display macro expansions in a separate window, instead of inline in
+ the source buffer, customize `macrostep-expand-in-separate-buffer' to
+ `t'. The default is `nil'. Whichever default behavior is selected,
+ the alternative behavior can be obtained temporarily by giving a
+ prefix argument to `macrostep-expand'.
+
+ To have `macrostep' ignore compiler macros, customize
+ `macrostep-expand-compiler-macros' to `nil'. The default is `t'.
+
+ Customize the faces `macrostep-macro-face',
+ `macrostep-compiler-macro-face', and `macrostep-gensym-1' through
+ `macrostep-gensym-5' to alter the appearance of macro expansions.
+
+
+1.3 Locally-bound macros
+────────────────────────
+
+ As of version 0.9, `macrostep' can expand calls to a locally-bound
+ macro, whether defined by a surrounding `(cl-)macrolet' form, or by
+ another macro-defining macro. In other words, it is possible to
+ expand the inner `local-macro' forms in both the following examples,
+ whether `local-macro' is defined by an enclosing `cl-macrolet' –
+
+ ┌────
+ │ (cl-macrolet ((local-macro (&rest args)
+ │ `(expansion of ,args)))
+ │ (local-macro (do-something)))
+ └────
+
+ – or by a macro which expands into `cl-macrolet', provided that its
+ definition of macro is evaluated prior to calling `macrostep-expand':
+
+ ┌────
+ │ (defmacro with-local-macro (&rest body)
+ │ `(cl-macrolet ((local-macro (&rest args)
+ │ `(expansion of ,args)))
+ │ ,@body))
+ │
+ │ (with-local-macro
+ │ (local-macro (do something (else)))
+ └────
+
+ See the `with-js' macro in Emacs's `js.el' for a real example of the
+ latter kind of macro.
+
+ Expansion of locally-bound macros is implemented by instrumenting
+ Emacs Lisp's macro-expander to capture the environment at point. A
+ similar trick is used to detect macro- and compiler-macro calls within
+ expanded text so that they can be fontified accurately.
+
+
+1.4 Expanding sub-forms
+───────────────────────
+
+ By moving point around in the macro expansion using
+ `macrostep-next-macro' and `macrostep-prev-macro' (bound to the `n'
+ and `p' keys), it is possible to expand other macro calls within the
+ expansion before expanding the outermost form. This can sometimes be
+ useful, although it does not correspond to the real order of macro
+ expansion in Emacs Lisp, which proceeds by fully expanding the outer
+ form to a non-macro form before expanding sub-forms.
+
+ The main reason to expand sub-forms out of order is to help with
+ debugging macros which programmatically expand their arguments in
+ order to rewrite them. Expanding the arguments of such a macro lets
+ you visualise what the macro definition would compute via
+ `macroexpand-all'.
+
+
+1.5 Extending macrostep for other languages
+───────────────────────────────────────────
+
+ Since version 0.9, it is possible to extend macrostep to work with
+ other languages besides Emacs Lisp. In typical Emacs fashion, this is
+ implemented by setting buffer-local variables to different function
+ values. Six buffer-local variables define the language-specific part
+ of the implementation:
+
+ • `macrostep-sexp-bounds-function'
+ • `macrostep-sexp-at-point-function'
+ • `macrostep-environment-at-point-function'
+ • `macrostep-expand-1-function'
+ • `macrostep-print-function'
+ • `macrostep-macro-form-p-function'
+
+ Typically, an implementation for another language would set these
+ variables in a major-mode hook. See the docstrings of each variable
+ for details on how each one is called and what it should return. At a
+ minimum, another language implementation needs to provide
+ `macrostep-sexp-at-point-function', `macrostep-expand-1-function', and
+ `macrostep-print-function'. Lisp-like languages may be able to reuse
+ the default `macrostep-sexp-bounds-function' if they provide another
+ implementation of `macrostep-macro-form-p-function'. Languages which
+ do not implement locally-defined macros can set
+ `macrostep-environment-at-point-function' to `ignore'.
+
+ Note that the core `macrostep' machinery only interprets the return
+ value of `macrostep-sexp-bounds-function', so implementations for
+ other languages can use any internal representations of code and
+ environments which is convenient. Although the terminology is
+ Lisp-specific, there is no reason that implementations could not be
+ provided for non-Lisp languages with macro systems, provided there is
+ some way of identifying macro calls and calling the compiler /
+ preprocessor to obtain their expansions.
+
+
+1.6 Bugs and known limitations
+──────────────────────────────
+
+ You can evaluate and edebug macro-expanded forms and step through the
+ macro-expanded version, but the form that `eval-defun' and friends
+ read from the buffer won't have the uninterned symbols of the real
+ macro expansion. This will probably work OK with CL-style gensyms,
+ but may cause problems with `make-symbol' symbols if they have the
+ same print name as another symbol in the expansion. It's possible that
+ using `print-circle' and `print-gensym' could get around this.
+
+ Please send other bug reports and feature requests to the author.

+
+;; A thin wrapper around Emacs's built-in `cmacexp' library to provide
+;; basic support for expanding C macros using the `macrostep' user

+;; type `M-x macrostep-expand'. The variables `c-macro-preprocessor'

+
+;; This is fairly basic compared to the Emacs Lisp `macrostep'. In

+
+;; To hide the buffer containing "cpp" warnings (not recommended), you

+;;; Commentary:
+
+;; `macrostep' is an Emacs minor mode for interactively stepping through
+;; the expansion of macros in Emacs Lisp source code. It lets you see
+;; exactly what happens at each step of the expansion process by
+;; pretty-printing the expanded forms inline in the source buffer, which is
+;; temporarily read-only while macro expansions are visible. You can
+;; expand and collapse macro forms one step at a time, and evaluate or
+;; instrument the expansions for debugging with Edebug as normal (but see
+;; "Bugs and known limitations", below). Single-stepping through the
+;; expansion is particularly useful for debugging macros that expand into
+;; another macro form. These can be difficult to debug with Emacs'
+;; built-in `macroexpand', which continues expansion until the top-level
+;; form is no longer a macro call.
+
+;; Both globally-visible macros as defined by `defmacro' and local macros
+;; bound by `(cl-)macrolet' or another macro-defining form can be expanded.
+;; Within macro expansions, calls to macros and compiler macros are
+;; fontified specially: macro forms using `macrostep-macro-face', and
+;; functions with compiler macros using `macrostep-compiler-macro-face'.
+;; Uninterned symbols (gensyms) are fontified based on which step in the
+;; expansion created them, to distinguish them both from normal symbols and
+;; from other gensyms with the same print name.
+
+;; As of version 0.9, it is also possible to extend `macrostep' to work
+;; with other languages with macro systems in addition to Emacs Lisp. An
+;; extension for Common Lisp (via SLIME) is in the works; contributions for
+;; other languages are welcome. See "Extending macrostep" below for
+;; details.
+
+
+;; 1 Key-bindings and usage
+;; ========================
+
+;; The standard keybindings in `macrostep-mode' are the following:
+
+;; e, =, RET : expand the macro form following point one step
+;; c, u, DEL : collapse the form following point
+;; q, C-c C-c: collapse all expanded forms and exit macrostep-mode
+;; n, TAB : jump to the next macro form in the expansion
+;; p, M-TAB : jump to the previous macro form in the expansion
+
+;; It's not very useful to enable and disable macrostep-mode directly.
+;; Instead, bind `macrostep-expand' to a key in `emacs-lisp-mode-map',
+;; for example C-c e:
+
+;; ,----
+;; | (define-key emacs-lisp-mode-map (kbd "C-c e") 'macrostep-expand)
+;; `----
+
+;; You can then enter macrostep-mode and expand a macro form completely
+;; by typing `C-c e e e ...' as many times as necessary.
+
+;; Exit macrostep-mode by typing `q' or `C-c C-c', or by successively
+;; typing `c' to collapse all surrounding expansions.
+
+
+;; 2 Customization options
+;; =======================
+
+;; Type `M-x customize-group RET macrostep RET' to customize options and
+;; faces.
+
+;; To display macro expansions in a separate window, instead of inline in
+;; the source buffer, customize `macrostep-expand-in-separate-buffer' to
+;; `t'. The default is `nil'. Whichever default behavior is selected,
+;; the alternative behavior can be obtained temporarily by giving a
+;; prefix argument to `macrostep-expand'.
+
+;; To have `macrostep' ignore compiler macros, customize
+;; `macrostep-expand-compiler-macros' to `nil'. The default is `t'.
+
+;; Customize the faces `macrostep-macro-face',
+;; `macrostep-compiler-macro-face', and `macrostep-gensym-1' through
+;; `macrostep-gensym-5' to alter the appearance of macro expansions.
+
+
+;; 3 Locally-bound macros
+;; ======================
+
+;; As of version 0.9, `macrostep' can expand calls to a locally-bound
+;; macro, whether defined by a surrounding `(cl-)macrolet' form, or by
+;; another macro-defining macro. In other words, it is possible to
+;; expand the inner `local-macro' forms in both the following examples,
+;; whether `local-macro' is defined by an enclosing `cl-macrolet' --
+
+;; ,----
+;; | (cl-macrolet ((local-macro (&rest args)
+;; | `(expansion of ,args)))
+;; | (local-macro (do-something)))
+;; `----
+
+;; -- or by a macro which expands into `cl-macrolet', provided that its
+;; definition of macro is evaluated prior to calling `macrostep-expand':
+
+;; ,----
+;; | (defmacro with-local-macro (&rest body)
+;; | `(cl-macrolet ((local-macro (&rest args)
+;; | `(expansion of ,args)))
+;; | ,@body))
+;; |
+;; | (with-local-macro
+;; | (local-macro (do something (else)))
+;; `----
+
+;; See the `with-js' macro in Emacs's `js.el' for a real example of the
+;; latter kind of macro.
+
+;; Expansion of locally-bound macros is implemented by instrumenting
+;; Emacs Lisp's macro-expander to capture the environment at point. A
+;; similar trick is used to detect macro- and compiler-macro calls within
+;; expanded text so that they can be fontified accurately.
+
+
+;; 4 Expanding sub-forms
+;; =====================
+
+;; By moving point around in the macro expansion using
+;; `macrostep-next-macro' and `macrostep-prev-macro' (bound to the `n'
+;; and `p' keys), it is possible to expand other macro calls within the
+;; expansion before expanding the outermost form. This can sometimes be
+;; useful, although it does not correspond to the real order of macro
+;; expansion in Emacs Lisp, which proceeds by fully expanding the outer
+;; form to a non-macro form before expanding sub-forms.
+
+;; The main reason to expand sub-forms out of order is to help with
+;; debugging macros which programmatically expand their arguments in
+;; order to rewrite them. Expanding the arguments of such a macro lets
+;; you visualise what the macro definition would compute via
+;; `macroexpand-all'.
+
+
+;; 5 Extending macrostep for other languages
+;; =========================================
+
+;; Since version 0.9, it is possible to extend macrostep to work with
+;; other languages besides Emacs Lisp. In typical Emacs fashion, this is
+;; implemented by setting buffer-local variables to different function
+;; values. Six buffer-local variables define the language-specific part
+;; of the implementation:
+
+;; - `macrostep-sexp-bounds-function'
+;; - `macrostep-sexp-at-point-function'
+;; - `macrostep-environment-at-point-function'
+;; - `macrostep-expand-1-function'
+;; - `macrostep-print-function'
+;; - `macrostep-macro-form-p-function'
+
+;; Typically, an implementation for another language would set these
+;; variables in a major-mode hook. See the docstrings of each variable
+;; for details on how each one is called and what it should return. At a
+;; minimum, another language implementation needs to provide
+;; `macrostep-sexp-at-point-function', `macrostep-expand-1-function', and
+;; `macrostep-print-function'. Lisp-like languages may be able to reuse
+;; the default `macrostep-sexp-bounds-function' if they provide another
+;; implementation of `macrostep-macro-form-p-function'. Languages which
+;; do not implement locally-defined macros can set
+;; `macrostep-environment-at-point-function' to `ignore'.
+
+;; Note that the core `macrostep' machinery only interprets the return
+;; value of `macrostep-sexp-bounds-function', so implementations for
+;; other languages can use any internal representations of code and
+;; environments which is convenient. Although the terminology is
+;; Lisp-specific, there is no reason that implementations could not be
+;; provided for non-Lisp languages with macro systems, provided there is
+;; some way of identifying macro calls and calling the compiler /
+;; preprocessor to obtain their expansions.
+
+
+;; 6 Bugs and known limitations
+;; ============================
+
+;; You can evaluate and edebug macro-expanded forms and step through the
+;; macro-expanded version, but the form that `eval-defun' and friends
+;; read from the buffer won't have the uninterned symbols of the real
+;; macro expansion. This will probably work OK with CL-style gensyms,
+;; but may cause problems with `make-symbol' symbols if they have the
+;; same print name as another symbol in the expansion. It's possible that
+;; using `print-circle' and `print-gensym' could get around this.
+
+;; Please send other bug reports and feature requests to the author.

+;;; Description:
+;;
+;; This is the SLY port of a contrib originally written for SLIME,
+;; with minimal changes, mostly "slime"->"sly" replacements.
+;;
+;; Fancier in-place macro-expansion using macrostep.el (originally
+;; written for Emacs Lisp). To use, position point before the
+;; open-paren of the macro call in a SLY source or REPL buffer, and
+;; type `C-c M-e' or `M-x macrostep-expand'. The pretty-printed
+;; result of `macroexpand-1' will be inserted inline in the current
+;; buffer, which is temporarily read-only while macro expansions are
+;; visible. If the expansion is itself a macro call, expansion can be
+;; continued by typing `e'. Expansions are collapsed to their
+;; original macro forms by typing `c' or `q'. Other macro- and
+;; compiler-macro calls in the expansion will be font-locked
+;; differently, and point can be moved there quickly by typing `n' or
+;; `p'. For more details, see the documentation of
+;; `macrostep-expand'.

+;;; Commentary:
+;;;
+;; An external contrib for SLY that enables different readtables to be
+;; active in different parts of the same file.
+;;
+;; SLY lives at https://github.com/capitaomorte/sly.
+;;
+;;; Installation:
+;;
+;; Since this is an external contrib with both Elisp and Lisp parts,
+;; merely loading the Elisp will have little effect. The contrib has
+;; to be registered in SLY's `sly-contribs' variable for SLY to take care
+;; of loading the Lisp side on demand.
+;;
+;; For convenience, the `sly-named-readtables-autoloads.el' Elisp file
+;; takes care of this automatically. So in your `~/.emacs' or
+;; `~/.emacs.d/init/el' init file:
+;;
+;; (setq inferior-lisp-program "/path/to/your/preferred/lisp")
+;; (add-to-list 'load-path "/path/to/sly")
+;; (require 'sly-autoloads)
+;;
+;; (add-to-list 'load-path "/path/to/sly-named-readtables")
+;; (require 'sly-named-readtables-autoloads)
+;;
+;; In case you already have SLY loaded and/or running, you might have to
+;; `M-x sly-setup' and `M-x sly-enable-contrib' to enable it.
+;;
+;; `sly-named-readtables' should now kick in in Lisp buffers. You must
+;; have `named-readtables` setup in your Lisp before it takes any actual
+;; effect though. That's easy, just `(ql:quickload :named-readtables)'.
