+ Wherever the \qsemicolon is indicated as a list parser in this guide, it can be replaced by any user-specified one character parser via the package option \fx{keyparser}. To avoid confusing the user-supplied parser with internal parsers, it is advisable to enclose the chosen character in curly braces. The braces will be stripped off internally. Please note that some of the characters that may be passed as a list parser may indeed be active; be careful to make them innocent before using them as a list/key parser. My advice is that the user sticks with the \qsemicolon as the key parser: the chances of it being made active by any package is minimal. If you have the chosen parser as literals in the callbacks of your keys, they have to be enclosed in curly braces.

+ The key-setting commands are \ffx'{\ltxkeyssetkeys,\ltxkeyssetrmkeys,\ltxkeyssetaliaskey}. If you must nest these commands beyond level~4, you have to raise the \fx{keydepthlimit} as a package option. The option \fx{keystacklimit} is an alias for \fx{keydepthlimit}.

+\defltablenote{4}{%
+ The use of an empty prefix will normally result from explicitly declaring the prefix as \fx{[]}, rather than leaving it undeclared. Undeclared prefixes assume the default value of \fx{KV}. An empty family will result from submitting the family as empty balanced curly braces \fx{{}}. If keys lack prefix and/or family, there is a strong risk of confusing key macros/functions. For example, without a prefix and/or family, a key named \fx{width} will have a key macro defined as \fx{\width}, which portents sufficient danger.

While some user interfaces of the \pkg'{ltxkeys} are similar to those of the \pkg'{xkeyval}, there are important differences in several areas of syntax, semantics, and internal implementation. The \pkg'{ltxkeys} also provides additional facilities (beyond the \pkg'{xkeyval}) for defining and managing keys. Several types of key (including ordinary keys, command keys, style keys, choice keys, list keys, boolean and biboolean keys) can be efficiently created and managed. In the \pkg'{ltxkeys}, the notions of \quoted{pre-setting} and \quoted{post-setting} keys are similar to those of the \pkg'{xkeyval}. But the \pkg'{ltxkeys} introduces additional concepts in this respect: \quoted{initialized} and \quoted{launched} keys. The latter are special preset keys. The pointer system of the \pkg'{xkeyval}, which was available only at key-setting time, is now available also at key definition time. One more type of pointer (\fx{\needvalue}) has been introduced to require users of \quoted{need-value keys} to supply values for those keys.
-Rather than simply issue an error for undefined keys when setting keys, the \pkg'{ltxkeys} provides the \quoted{undefined keys} and \quoted{undefined options} handlers, which are user-customizable. Other new concepts include \quotedlist{definable keys, cross-family keys, option keys, non-option keys, handled keys, pathkeys, key commands, key environments}, accessing the saved value of a key outside \hx{\setkeys} or similar commands, and declaring multiple keys and options (of all genre) using only one command. The notion of pathkeys is particularly interesting and powerful. Users more interested in this concept and its applications can skip many sections of this guide on their way to \sref{sec:pathkeys}.

It is not advisable to alias the commands of the \pkg'{xkeyval} to the commands of the \pkg'{ltxkeys}.

List processor keys (or lisp keys) are ordinary keys that accept a parser-separated list as a user input and process each element of the list. The key's callback \ang{cbk} is then a list processor, but the key author doesn't have to design and suggest his own looping system. All he has to do is to pass the parameter \fx{#1}, representing the individual items of the list, to the key's callback. The key will internally do the loop and process the list (\ie, the user input).

The unprocessed items will be handled by the command \fx{\ltxkeysdoremainder}, which can be redefined by the user.

Biboolean keys always assume opposite states: when one is true, the other is automatically toggled to false; and vice versa. Think of the options \hx{draft} and \hx{final} in a document class, but note that traditional document classes don't currently use biboolean keys. The callback \ang{cbk1} belongs to the boolean key \ang{bl1}, while \ang{cbk2} is of \ang{bl2}.

Biboolean keys have equal symmetry (\ie, they can call each other with equal propensity) and they won't bomb out in an infinite reentrance. They normally would know if and when they call each other, or if they're being called by some other keys.

Switch keys look like boolean keys and they expect the same value set as boolean keys, namely, \fnz*{true, false}, but they are cheaper. Internally the value set of a switch key is \fnz*{00,01}. So, while the user input for a switch key must lie in the set \fnz*{true, false}, the input is internally converted to \fnz*{00,01}. This allows the values of switch keys to be tested with \tex's \hx{\if}. While each new boolean results in the creation of three commands, every new switch requires only one command.

If \ang{mp} is specified, a switch of the form \mpkey will be created at key definition, which will be set by \fx{\ltxkeyssetkeys} according to the user input. If \ang{mp} is not specified, a switch of the form \ipreffamkey{switch} will instead be created.

There are times when it is required to use the same, or nearly the same, set of keys for different functions and purposes, and thus for different key families and prefixes. We call such keys \quoted{cross-family keys} or \quoted{xfamily keys}. Such keys bear the same names across key families and key prefixes. For example, the \pkg'{xwatermark} defines three functions (\ffx'{\xwmminipage,\xwmboxedminipage,\xwmcolorbox}) using nearly the same set of keys. In each of the three families, the keys bear the same or similar names and they have similar callbacks. The management of cross-family keys can be simplified by using the tools of this section. Even if not all the cross-family keys are needed in all the families to which they may belong, there are still advantages in using this type of keys when some of the keys cut across families.

+Here, \ang{keyvals} is a comma-separated list of \keyval pairs to be preset or postset in the given families. The optional exclamation mark \redclam here, as in many (but not all) instances in the \pkg'{ltxkeys}, means that the assignments would be done and the lists built globally rather than locally. \quoted{Presetting keys} means \quoted{these keys should be set before setting other keys in the user input in every run of the command \fx{\ltxkeyssetkeys} for the given key prefix and family}. Keys contained in the current user input to \fx{\ltxkeyssetkeys} will not be preset or postset, \ie, the current user key-value pairs will always take priority over preset and postset values. The command \fx{\ltxkeysaddpresetkeys} is an alias for \fx{\ltxkeyspresetkeys}, and this helps explain that \fx{\ltxkeyspresetkeys} is indeed a list merger. Neither the command \fx{\ltxkeyspresetkeys} nor \fx{\ltxkeyspostsetkeys} set keys itself, contrary to what the names might suggest.

+\quoted{Post-setting keys} means \quoted{these keys are to be set after setting other keys in the user input in every run of the command \fx{\ltxkeyssetkeys} for the given key prefix and family}. \fx{\ltxkeysaddpostsetkeys} is an alias for \fx{\ltxkeyspostsetkeys}.

\docsection(sec:handledkeys)<handled keys>{Handled keys}
As mentioned in \sref{sec:unknownkeyhandler}, handled keys are keys defined in a macro that is key-prefix and key-family dependent. They are defined as a list in a macro so that they can be used for future applications, such as deciding if a dependant key of a style key should be defined or redefined on the fly. Handled keys should be defined, or added to, using key prefix, family and key names. You can define or add to handled keys by the following command:

However, when dealing with \quoted{pathkeys} (see \sref{sec:pathkeys}) the term excludes the macro prefix. You can reserve key path or bases (\ie, bar future users from using the same path or bases) by the following commands.

-
-Let us start this section with a welcome message: you don't have to repeatedly type in long key paths and commands when using pathkeys. There is plenty of help ahead on how to reduce estate when using pathkeys.
-
-The \pkg'{pathkeys} can be loaded on its own (via \hx{\RequirePackage} or \hx{\usepackage}) or as an option to the \pkg'{ltxkeys} (see \sref{tab:pkgoptions})\footnote{The user has no access to the command \fx{\pathkeys} unless he/she first loads \pkg'{pathkeys}.}. All the options listed in \sref{tab:pkgoptions} are accepted by the \pkg'{pathkeys}. They are all passed on to \pkg'{ltxkeys}, except \fx{pathkeys} that is simply ignored by \pkg'{pathkeys}.
-
-Pathkeys are keys with a tree or directory structure\footnote{This might sound like \textpgfkeys, but the semantics, syntaxes, and the implementation here are all different from those of \textpgfkeys.}. When defining and setting pathkeys, the full key path is usually required. This is also the case when seeking the current value or state of a key. When using pathkeys the user is relieved of the need to known and remember where the optional arguments have to be placed in calls to macros. And like the commands \ffx'{\ltxkeysdefinekeys, \ltxkeysdeclarekeys}, pathkeys are automatically initialized after definition, \ie, they are automatically set with their default values. Boolean keys are set with a default value of \quoted{false} irrespective of the user-specified default value. See \sref{sec:definekeys,sec:declarekeys} for an explanation of this philosophy.
-
-The command for defining and setting pathkeys is \fx{\pathkeys}, which has the following syntax. The same command is used for several other tasks related to pathkeys. The \quoted{flag} entry in the argument of \fx{\pathkeys} determines the action that the command is expected to take.
-
-\start+{newmacro}[\pathkeys]
-\pathkeys|*|'{|A(paths)/|A(flag)|R(:) |A(attrib)}
-\finish{newmacro}
-\fxim*{\pathkeys}
-
-The \stform of \fx{\pathkeys} will expand its argument once before commencing the loop and executing the codes on the specified paths. The \pmform is equivalent to invoking the package option \fx{endcallbackline} before calling \fx{\pathkeys}. Using both \redstar and \redprime makes \hx{\endlinechar} $-1$ but the effect is not enforced, since in the \stform of \fx{\pathkeys} the argument has already been read.
-
-In the argument of command \fx{\pathkeys}, \ang{paths} has the syntax
-
-\start+{newmacro}[Paths in \pathkeys]
-|A(main-1)/|A(sub-1)/|A(subsub-1)|R(,)|A(main-2)/|A(sub-2)/|A(subsub-2),...|R(,)etc.
-\finish{newmacro}
-\fxim*{\pathkeys}
-
-in which individual paths are separated by \qcomma. The quantity \ang{main} is the main path and \ang{sub} is the sub path, \eetc. It should be noted that there is no forward slash ~(\fx{/}) before \ang{paths} or \ang{main}. If the path is empty, the default path \quotedfx{pathkeys@default@main/pathkeys@default@sub}, or the user-supplied current path (see later), is used. \emph{Note, however, that when the current path is empty, the default path is not resorted to automatically; you have to indicate that this is your choice.} You can call \fx{\pathkeysusedefaultpath} to indicate that you really want the default path to be the current path. The aim is that users don't leave out the path when they don't actually intend it to be empty. There is more about the default and current paths later in this guide.
-
-The \ang{attrib}, the property of a pathkey, is determined by the quantity called \ang{flag}. The \ang{flag} determines the action the command \fx{\pathkeys} takes, and must be a member of the set described in \sref{tab:flags}. The action specified by \ang{flag} is, if applicable on all the given paths, taken on all the given paths. Multiple paths should invariably be comma-separated. See the notes of \sref{tab:flags} for the \ang{attrib}'s of the flags. The attributes describe the arguments associated with the flags, \ie, the quantities expected after the \qcolon in the argument of \fx{\pathkeys}. The \ang{na} is the list of keys that are ignored by the \ang{flag}'s action. If it is present in the attribute \ang{attrib} part of \fx{\pathkeys}, it must always be given in square brackets \quotedfx{[]} (see \sref{nte:pathkeys-flags}). Not all the flags expect, or can process, the \ang{na} list.
-
-Some important points about the command \fx{\pathkeys}:
-\begin{enum}
-\item A key message of the above syntax of \ang{paths} is that several paths can be submitted to \fx{\pathkeys} in one go. The attribute \ang{attrib} will then apply to all the given paths, according to the given \ang{flag}. If \ang{flag} involves defining keys, the keys will be defined on all the listed paths. If \ang{flag} involves determining if a key is defined on any of the given paths, all the listed paths are searched to find the key.
-\item Within the command \fx{\pathkeys}, if the package option \fx{endcallbackline} is enabled, every line implicitly ends with a comment sign. Invariably, within \fx{\pathkeys} the \quoted{at sign} (\fx{@}) has category code~11 (letter). So no need to reassign this category code to~11 within \fx{\pathkeys}.
-\item For flags with \redstar, \redplus and \redclam signs, the user should make sure there is no space between the flag and its star, plus or exclamation sign: such a space will not be zapped internally, since syntactic matching is used. The sign is part of the flag's name.
-\end{enum}
-
-\newltablenote{pathkeys-flags-1}{%
- The flag \fx{declareoptions}\Redstar simply signifies the user's aim to define definable options; it has nothing to do with the \stform of the command \fx{\ltxkeys@declareoption} of \sref{sec:declareoption}. The attribute is the same as for \fx{define} flag.
-}
-\newltablenote{pathkeys-flags-2}{%
- The key or option handler can have up to a maximum of~4 arguments. The arguments of the unknown key or option handler are the main path (argument 1); subpaths, separated by forward slash (argument 2); key name (argument 3), and the current key value (argument 4). The handler can/should be defined by the user (see \sref{sec:unknownkeyhandler}).

-See \sref{sec:options-pathkeys} for further examples of the use of ignored keys. Here we can see that a value is provided for \quoted{keyb} and yet we're ignoring the key.

Therefore, \ang{na} keys are much more useful than the above example demonstrates\@gobble{.}

The commands \ffx'{\ifpathkeysvalTF, \ifpathkeyskeyvalTF} also test the current state of the boolean key \ang{pk} but return \ang{true} or \ang{false} in a \latex syntax. The command \fx{\pathkeysstorevalue} stores the current value of key \ang{pk} in the given command \ang{cmd}.

-\ltsnote
-If called outside an assignment or document environment, the macros \ffx'{\pathkeysval, \pathkeyskeyval} can give \quoted{no document error}, to signify that a token has been output outside these situations. And one source of problem with \ffx'{\ifpathkeysval, \ifpathkeyskeyval} is to omit \fx{\then} after their argument. If you find yourself typing long key paths and the commands \ffx'{\pathkeysval, \pathkeyskeyval}, \eetc, repeatedly, there is help ahead on how to reduce the amount of typing required in using pathkeys.

-When using pathkeys (and in general the commands \ffx'{\ltxkeysdefinekeys,\ltxkeysdeclarekeys}), there is a potential problem in deploying forward slashes in key defaults and macros without enclosing those slashes in curly braces. They will confuse the parser. Several solutions exist, including tweaking the relevant internal parser, but I haven't decided on the optimal solution to this possibility. For example, the following will fail:
-
-\start{example}[Forward slashes in key defaults and macros]
-\pathkeys{fam/subfam/subsubfam/define*:

-As seen above, the estate for deploying pathkeys can be large when compared with the amount of typing required for conventional keys presented in the previous chapters. To reduce the estate, the first line of thought is to store any long path in a macro and call the macro instead of the path. The path is always fully expanded under safe actives. The following example demonstrates this approach.

-\item The commands \ffx'{\pathkeysundefpaths, \pathkeysgundefpaths} undefine the comma-separated list of \ang{pathnames} locally and globally, respectively.
-\item The command \fx{\pathkeysassignpaths} defines a series of unique pathnames as shown by its use syntax above. The equality sign in that syntax is mandatory. Existing paths are not overwritten.
-\item The commands \ffx'{\pathkeysusepaths,\pathkeysusepath} are synonymous and expand the comma-separated entries in \ang{pathnames} or \ang{pathname} to their full meaning. The action specified by \ang{flag} is then executed on all the listed paths.

-We begin the section with a note of caution: path changes within the \fx{\pathkeys} command are limited in scope, since the current path is pushed upon entry into this command and popped on exit. To change the current path while in \fx{\pathkeys} command, use the \fx{normalcode} flag of \sref{tab:flags}.

-If the key path is empty, then the current path will be used. If there is no current path, the default path will be used, \emph{but only after the user has issued \fx{\pathkeysusedefaultpath}}. The default path is \quotedfx{pathkeys@default@main/pathkeys@default@sub}. The default path can be made the current path by invoking the command \fx{\pathkeysusedefaultpath}, which is parameterless. The default path can be changed by the one-parameter commands \ffx'{\pathkeysaddtodefaultpath, \pathkeyschangedefaultpath}.
-
-The current path can be declared by providing an argument to the non-expandable one-parameter command \fx{\pathkeyscurrentpath}. The declared current path will be available in the macro \fx{\pathkeyscurrentpathtext}, which is expandable. \emph{A call to \fx{\pathkeyscurrentpath} immediately changes the current path}. The internal macro \fx{\pathkeyscurrentpathtext} always holds the current path. It is possible for the user to change \fx{\pathkeyscurrentpathtext} directly, but this is not recommended, since it will not allow the path history to be revised. That is why \fx{\pathkeyscurrentpathtext} doesn't look like a user command. For example, the following assignment is possible but not advisable:
-
-\start{syntax}[\pathkeyscurrentpathtext]
-\let\pathkeyscurrentpathtext=\pathkeysdefaultpath
-\finish{syntax}
-\fxi*{\pathkeyscurrentpathtext}
-
-This should only be done via \fx{\pathkeysusedefaultpath}.
-
-If you change the default path by calling any of the commands \ffx'{\pathkeysaddtodefaultpath, \pathkeyschangedefaultpath}, you will have to call \fx{\pathkeysusedefaultpath} to update \fx{\pathkeyscurrentpathtext}. For some reason, this is not done automatically.
-
-It isn't mandatory, but it is useful, to first push the prevailing path before changing it. This can be done by calling the parameterless command \fx{\pathkeyspushcurrentpath}. When you're done with the current path, you can revert to the path before the current path by calling the command \fx{\pathkeyspopcurrentpath}. You can get the entire history of path changes from the container \fx{\pathkeyspathhistory}, which is useful in complex situations. However, it should be noted that \fx{\pathkeyspathhistory} doesn't contain a chronological order of path changes: if a path is already contained in it, it wouldn't be added again. Also, \fx{\pathkeyspathhistory} is built and revised globally: path changes in local groups will appear in \fx{\pathkeyspathhistory} outside the groups. The commands \ffx'{\pathkeysundefpaths, \pathkeysgundefpaths} don't affect this behavior.
-
-I can't see a user need for it, but you can use the command \fx{\pathkeysifnopath} to ascertain if a given \ang{path} actually contains a valid path. This is used internally.

-
-Before the current path is resorted to (\ie, used), the path specified in the the commands \ffx{\pathkeys, \pathkeysval, \ifpathkeysval}, \eetc must be empty (\ie, no main and no subs). Therefore, in any given setting, the path that is dominant can be made current so that it isn't given in \ffx{\pathkeys, \pathkeysval, \ifpathkeysval}, \eetc. The non-dominant paths could then be listed in full. Of course, there can't be more than one current path. Perhaps a better approach is to use \ffx{\pathkeysnewpath, \pathkeysusepaths}, etc.

-The reason is that \ttx{keyb} was defined when the default was being set up for \ttx{keya} after the definition of \ttx{keya}. The second setting of \ttx{keya} prompts an error that \ttx{keyb} is being redefined. Notice that \ttx{keyb} is to be defined uniquely by the flag \fx{define}\Redstar. To avoid this type of error, you may consider removing \redstar from \fx{define}\Redstar.

-To use the command \fx{\pathkeys} for declaring class or package options, the user should simply call \fx{\pathkeys} with the flag \fx{declareoptions} (or \fx{declareoptions}\Redstar for defining only unique options).

This too can be changed via the package option \ftfx{keyparser} (see \sref{tab:pkgoptions}).}. The default list parser for classes is double bar \quotedfx{||}, but this can be changed, within limits, by the user. It can be changed to one or a combination of characters that aren't in the set \fx{{,;:@|/}}. Active bars that are list parsers will be normalized internally. Those bars that aren't list parsers will be left intact.

\docsection(sec:weirdargs){Keys with argument patterns}
\quoted{Argument pattern} simply means the structure of the arguments that a key's macro expects in order to execute the key's callback. In \pkg'{ltxkeys} it is possible to specify the nature of the parameter pattern for the key macro, but this makes sense only in the case of ordinary (\fx{ord}), command (\fx{cmd}) and style (\fx{sty} or \fx{sty}\Redstar) keys. Boolean and choice keys can't have weird (\ie, multiple or delimited) arguments, since their expected values are restricted: boolean keys must have a value of either \hx{true} or \hx{false}, and choice keys must have \quoted{nominations}, \ie, admissible or alternate values. Therefore, the concept introduced in this section applies only to the following key-definition commands:

Here, \ang{paren} is the parent key of dependants keys; \ang{deps} is the full specification of new or existing dependant keys (as in \sref{sec:stylekeys}), with their default values and callbacks; \ang{olddeps} are the old dependants to replace with \ang{newdeps}. This would require patching macros of the form \jpreffamkey{dependants}, which might have nested parametered-commands.

+Normally, the command \fx{\patchcmd} of \cref{sec:cmd-patch} (and hence \fx{\ltxkeyspatchcallback}) doesn't allow nested commands, and hence no doubling of the parameter character in the replacement text. If you want to nest commands or double the parameter character in the replacement text, you need to use the \stform of \fx{\patchcmd} or \fx{\ltxkeyspatchcallback} (see example below). \ No newline at end of file
