	30	;;; Commentary:
	31
	32	;; Smartparens is minor mode for Emacs that deals with parens pairs
	33	;; and tries to be smart about it. It started as a unification effort
	34	;; to combine functionality of several existing packages in a single,
	35	;; compatible and extensible way to deal with parentheses, delimiters,
	36	;; tags and the like. Some of these packages include autopair,
	37	;; textmate, wrap-region, electric-pair-mode, paredit and others. With
	38	;; the basic features found in other packages it also brings many
	39	;; improvements as well as completely new features.

	2313
	2314	If the ACTIONS argument has value :rem, the pair is removed.
	2315	This can be used to remove default pairs you don't want to use.
	2316	For example: (sp-pair \"[\" nil :actions :rem)
	2317
	2318	WHEN is a list of predicates that test whether the action
	2319	should be performed in current context. The values in the list
	2320	should be names of the predicates (that is symbols, not
	2321	lambdas!). They should accept three arguments: opening
	2322	delimiter (which uniquely determines the pair), action and
	2323	context. The context argument can have values:
	2324
	2325	- string - if point is inside string.
	2326	- comment - if point is inside comment.
	2327	- code - if point is inside code. This context is only
	2328	recognized in programming modes that define string semantics.
	2329
	2330	If any filter returns t, the action WILL be performed. A number
	2331	of filters are predefined: `sp-point-after-word-p',
	2332	`sp-point-before-word-p', `sp-in-string-p',
	2333	`sp-point-before-eol-p' etc.
	2334
	2335	When clause also supports a special format for delayed insertion.
	2336	The condition is a list with commands, predicates (with three
	2337	arguments as regular when form) or strings specifying the last
	2338	event. All three types can be combined in one list. The pair
	2339	will be inserted after the next command if it matches the any
	2340	command on the list, if the last event matches any string on the
	2341	list or if any predicate returns true. If the pair's :when
	2342	clause contains this special form, it will never be immediately
	2343	inserted and will always test for delayed insertion.
	2344
	2345	UNLESS is a list of predicates. The conventions are the same as
	2346	for the WHEN list. If any filter on this list returns t, the
	2347	action WILL NOT be performed. The predicates in the WHEN list
	2348	are checked first, and if any of them succeeds, the UNLESS list
	2349	is not checked.
	2350
	2351	Note: the functions on the WHEN/UNLESS lists are also called
	2352	\"filters\" in the documentation.
	2353
	2354	All the filters are run after the trigger character is
	2355	inserted.
	2356
	2357	PRE-HANDLERS is a list of functions that are called before there
	2358	has been some action caused by this pair. The arguments are the
	2359	same as for filters. Context is relative to the point before
	2360	the last inserted character. Because of the nature of the
	2361	wrapping operation, this hook is not called if the action is
	2362	wrapping.
	2363
	2364	POST-HANDLERS is a list of functions that are called after there
	2365	has been some action caused by this pair. The arguments are the
	2366	same as for filters. Context is relative to current position of
	2367	point after the closing pair was inserted.
	2368
	2369	After a wrapping action, the point might end on either side of
	2370	the wrapped region, depending on the original direction. You can
	2371	use the variable `sp-last-wrapped-region' to retrieve information
	2372	about the wrapped region and position the point to suit your
	2373	needs.
	2374
	2375	A special syntax for conditional execution of hooks is also
	2376	supported. If the added item is a list (function command1
	2377	command2...), where function is a 3 argument function described
	2378	above and command(s) can be either name of a command or a string
	2379	representing an event. If the last command or event as described
	2380	by `single-key-description' matches any on the list, the hook
	2381	will be executed. This means these hooks are run not after the
	2382	insertion, but after the next command is executed.
	2383
	2384	Example:
	2385	((lambda (id act con)
	2386	(save-excursion
	2387	(newline))) \"RET\" newline)
	2388
	2389	This function will move the closing pair on its own line only if
	2390	the next command is `newline' or is triggered by RET. Otherwise
	2391	the pairs stay on the same line.
	2392
	2393	WRAP is a key binding to which a \"wrapping\" action is bound.
	2394	The key should be in format that is accepted by `kbd'. This
	2395	option binds a lambda form:
	2396
	2397	`(lambda (&optional arg)
	2398	(interactive \"P\")
	2399	(sp-wrap-with-pair ,OPEN))
	2400
	2401	to the specified key sequence. The binding is added to global
	2402	keymap. When executed, it wraps ARG (default 1) expressions with
	2403	this pair (like `paredit-wrap-round' and friends). Additionally,
	2404	it accepts the same prefix arguments as `sp-select-next-thing'.
	2405
	2406	BIND is equivalent to WRAP. It is a legacy setting and will be
	2407	removed soon.
	2408
	2409	INSERT is a key binding to which an \"insert\" action is bound.
	2410	The key should be in format that is accepted by `kbd'. This is
	2411	achieved by binding a lambda form:
	2412
	2413	(lambda () (interactive) (sp-insert-pair \"pair-id\"))
	2414
	2415	to the supplied key, where pair-id is the open delimiter of the
	2416	pair. The binding is added to the global map. You can also bind
	2417	a similar lambda manually. To only bind this in specific major
	2418	modes, use this property on `sp-local-pair' instead."

	2469	MODES can be a single mode or a list of modes where these settings
	2470	should be applied.
	2471
	2472	PREFIX is a regular expression matching an optional prefix for
	2473	this pair in the specified major modes. If not specified, the
	2474	characters of expression prefix syntax class are automatically
	2475	considered instead. This can be used to attach custom prefixes
	2476	to pairs, such as prefix \"\\function\" in \\function{arg} in
	2477	`LaTeX-mode'.
	2478
	2479	SUFFIX is a regular expression matching an optional suffix for
	2480	this pair in the specified major modes. If not specified, the
	2481	characters of punctuation syntax class are automatically
	2482	considered instead.
	2483
	2484	The rest of the arguments have same semantics as in `sp-pair'.
	2485
	2486	If the pair is not defined globally, ACTIONS defaults to (wrap
	2487	insert) instead of (:add) (which inherits global settings)
	2488
	2489	The pairs are uniquely identified by the opening delimiter. If you
	2490	replace the closing one with a different string in the local
	2491	definition, this will override the global closing delimiter.
	2492
	2493	The list arguments can optionally be of form starting with
	2494	\":add\" or \":rem\" when these mean \"add to the global list\"
	2495	and \"remove from the global list\" respectively. Otherwise,
	2496	the global list is replaced. If you wish to both add and remove
	2497	things with single call, use \"((:add ...) (:rem ...))\" as an
	2498	argument. Therefore,
	2499
	2500	:when '(:add my-test)
	2501
	2502	would mean \"use the global settings for this pair, but also this
	2503	additional test\". If no value is provided for list arguments,
	2504	they default to \"(:add)\" which means they inherit the list from
	2505	the global definition.
	2506
	2507	To disable a pair in a major mode, simply set its actions set to
	2508	nil. This will ensure the pair is not even loaded when the mode is
	2509	activated.
	2510
	2511	If WRAP is non-nil, the binding is added into major mode keymap
	2512	called \"foo-mode-map\". If the mode does not follow this
	2513	convention, you will need to bind the function manually (see
	2514	`sp-pair' to how the function is named for each particular pair).
	2515	The bindings are not added into `smartparens-mode-map' to prevent
	2516	clashes between different modes.
	2517
	2518	BIND is equivalent to WRAP. It is a legacy setting and will be
	2519	removed soon.
	2520
	2521	The binding for INSERT follows the same convention as BIND. See
	2522	`sp-pair' for more info.
	2523
	2524	You can provide a function SKIP-MATCH, that will take three
	2525	arguments: the currently matched delimiter, beginning of match
	2526	and end of match. If this function returns true, the
	2527	`sp-get-paired-expression' matcher will ignore this match. You
	2528	can use this to skip over expressions that serve multiple
	2529	functions, such as if/end pair or unary if in Ruby or * in
	2530	markdown when it signifies list item instead of emphasis. In
	2531	addition, there is a global per major-mode option, see

	2592
	2593	If the opening tag contains the _ character, after you type the
