% A form of \verb that allows linebreaks at certain characters or
% combinations of characters, accepts reconfiguration, and can usually
% be used in the argument to another command. It is intended for email
% addresses, hypertext links, directories/paths, etc., which normally
% have no spaces. The font may be selected using the \urlstyle command,
% and new url-like commands can be defined using \urldef.
%
% Usage: Conditions:
% \url{ } If the argument contains any "%" or "^^", or ends with
% "\", it can't be used in the argument to another command.
% The argument must not contain unbalanced braces.
% \url| | ...where "|" is any character not used in the argument and not
% "{" or a space. The same restrictions as above except that the
% argument may contain unbalanced braces.

% url.sty ver 3.3 12-Apr-2006 Donald Arseneau [email protected]
%
% This package defines "\url", a form of "\verb" that allows linebreaks,
% and can often be used in the argument to another command. It can be
% configured to print in different formats, and is particularly useful for
% hypertext links, email addresses, directories/paths, etc. The font may
% be selected using the "\urlstyle" command and pre-defined text can be
% stored with the "\urldef" command. New url-like commands can be defined,
% and a "\path" command is provided this way.
%
% Usage: Conditions:
% \url{ } If the argument contains any "%", "#", or "^^", or ends with
% "\", it can't be used in the argument to another command.
% The argument must not contain unbalanced braces.
% \url| | ...where "|" is any character not used in the argument and not
% "{" or a space. The same restrictions as above except that the
% argument may contain unbalanced braces.
% \xyz for "\xyz" a defined-url; this can be used anywhere, no matter
% what characters it contains.
%
% The "\url" command is fragile, and its argument is likely to be very
% fragile, but a defined-url is robust.
%
% Package Option: obeyspaces
% Ordinarily, all spaces are ignored in the url-text. The "[obeyspaces]"
% option allows spaces, but may introduce spurious spaces when a url
% containing "\" characters is given in the argument to another command.
% So if you need to obey spaces you can say "\usepackage[obeyspaces]{url}",
% and if you need both spaces and backslashes, use a `defined-url' for
% anything with "\".
%
% Package Option: hyphens
% Ordinarily, breaks are not allowed after "-" characters because this
% leads to confusion. (Is the "-" part of the address or just a hyphen?)
% The package option "[hyphens]" allows breaks after explicit hyphen
% characters. The "\url" command will *never ever* hyphenate words.
%
% Package Option: spaces
% Likewise, breaks are not usually allowed after spaces under the
% "[obeyspaces]" option, but giving the options "[obeyspaces,spaces]"
% will allow breaks at those spaces. (Note that it seems logical to
% allow the sole option "[spaces]" to let input spaces indicate break
% points, but not to display them in the output. This would be easy to
% implement, but is left out to avoid(?) confusion.)
%
% Package Option: lowtilde
% Normal treatment of the ~ character is to use the font's "\textasciitilde"
% character, if it has one (or claims to). Otherwise, the character is
% faked using a mathematic "\sim". The "[lowtilde]" option causes a
% faked character to be used always (and a bit lower than usual).
%
% Defining a defined-url:
% Take for example the email address "myself%[email protected]" which could
% not be given (using "\url" or "\verb") in a caption or parbox due to the
% percent sign. This address can be predefined with
% \urldef{\myself}\url{myself%[email protected]} or
% \urldef{\myself}\url|myself%[email protected]|
% and then you may use "\myself" instead of "\url{myself%[email protected]}"
% in an argument, and even in a moving argument like a caption because a
% defined-url is robust.
%
% Style:
% You can switch the style of printing using "\urlstyle{tt}", where "tt"
% can be any defined style. The pre-defined styles are "tt", "rm", "sf",
% and "same" which all allow the same linebreaks but different fonts --
% the first three select a specific font and the "same" style uses the
% current text font. You can define your own styles with different fonts
% and/or line-breaking by following the explanations below. The "\url"
% command follows whatever the currently-set style dictates.
%
% Alternate commands:
% It may be desireable to have different things treated differently, each
% in a predefined style; e.g., if you want directory paths to always be
% in typewriter and email addresses to be roman, then you would define new
% url-like commands as follows:
%
% \DeclareUrlCommand\email{\urlstyle{rm}}
% \DeclareUrlCommand\directory{\urlstyle{tt}}
%
% In fact, the "\directory" example is exactly the "\path" definition which
% is pre-defined in the package. If you look above, you will see that "\url"
% is defined with
% \DeclareUrlCommand\url{}
% I.e., using whatever "\urlstyle" and other settings are already in effect.
%
% You can make a defined-url for these other styles, using the usual
% "\urldef" command as in this example:
%
% \urldef{\myself}{\email}{myself%[email protected]}
%
% which makes "\myself" act like "\email{myself%[email protected]}",
% if the "\email" command is defined as above. The "\myself" command
% would then be robust.
%
% Defining styles:
% Before describing how to customize the printing style, it is best to
% mention something about the unusual implementation of "\url". Although
% the material is textual in nature, and the font specification required
% is a text-font command, the text is actually typeset in *math* mode.
% This allows the context-sensitive linebreaking, but also accounts for
% the default behavior of ignoring spaces. Now on to defining styles.
%
% To change the font or the list of characters that allow linebreaks, you
% could redefine the commands "\UrlFont", "\UrlBreaks", "\UrlSpecials" etc.
% directly in the document, but it is better to define a new `url-style'
% (following the example of "\url@ttstyle" and "\url@rmstyle") which defines
% all of "\UrlBigbreaks", "\UrlNoBreaks", "\UrlBreaks", "\UrlSpecials", and
% "\UrlFont".
%
% Changing font:
% The "\UrlFont" command selects the font. The definition of "\UrlFont"
% done by the pre-defined styles varies to cope with a variety of LaTeX
% font selection schemes, but it could be as simple as "\def\UrlFont{\tt}".
% Depending on the font selected, some characters may need to be defined
% in the "\UrlSpecials" list because many fonts don't contain all the
% standard input characters.
%
% Changing linebreaks:
% The list of characters that allow line-breaks is given by "\UrlBreaks"
% and "\UrlBigBreaks", which have the format "\do\c" for character "c".
% The differences are that `BigBreaks' usually have a lower penalty and have
% different breakpoints when in sequence (as in "http://"): `BigBreaks'
% are treated as mathrels while `Breaks' are mathbins (see The TeXbook,
% p.170). In particular, a series of `BigBreak' characters will break at
% the end and only at the end; a series of `Break' characters will break
% after the first and after every following *pair*; there will be no
% break after a `Break' character if a `BigBreak' follows. In the case
% of "http://" it doesn't matter whether ":" is a `Break' or `BigBreak' --
% the breaks are the same in either case; but for DECnet nodes with "::"
% it is important to prevent breaks *between* the colons, and that is why
% colons are `BigBreaks'.
%
% It is possible for characters to prevent breaks after the next following
% character (I use this for parentheses). Specify these in "\UrlNoBreaks".
%
% You can do arbitrarily complex things with characters by making them
% active in math mode (mathcode hex-8000) and specifying the definition(s)
% in "\UrlSpecials". This is used in the rm and sf styles for OT1 font
% encoding to handle several characters that are not present in those
% computer-modern style fonts. See the definition of "\Url@do", which
% is used by both "\url@rmstyle" and "\url@sfstyle"; it handles missing
% characters via "\UrlSpecials". The nominal format for setting each
% special character "c" is: "\do\c{}", but you can include
% other definitions too.
%
% If all this sounds confusing ... well, it is! But I hope you won't need
% to redefine breakpoints -- the default assignments seem to work well for
% a wide variety of applications. If you do need to make changes, you can
% test for breakpoints using regular math mode and the characters "+=(a".
%
% You can allow some spacing around the breakable characters by assigning
% \Urlmuskip = 0mu plus 1mu
% You can change the penalties used for BigBreaks and Breaks by assigning
% \mathchardef\UrlBreakPenalty=100 \mathchardef\UrlBigBreakPenalty=100
% The default penalties are "\binoppenalty" and "\relpenalty". These have
% such odd non-LaTeX syntax because I don't expect people to need to
% change them often.
%
% Yet more flexibility:
% You can also customize the verbatim text by defining "\UrlRight" and/or
% "\UrlLeft", e.g., for ISO formatting of urls surrounded by "< >", define
%
% \DeclareUrlCommand\url{\def\UrlLeft{}%
% \urlstyle{tt}}
%
% The meanings of "\UrlLeft" and "\UrlRight" are *not* reproduced verbatim.
% This lets you use formatting commands there, but you must be careful not
% to use TeX's special characters ("\^_%~#$&{}" etc.) improperly.
% You can also define "\UrlLeft" to reprocess the verbatim text, but the
% format of the definition is special:
%
% \def\UrlLeft#1\UrlRight{ ... do things with #1 ... }
%
% Yes, that is "#1" followed by "\UrlRight" then the definition. For
% example, to put a hyperTeX hypertext link in the DVI file:
%
% \def\UrlLeft#1\UrlRight{\special{html:}#1\special{html:}}
%
% Using this technique, url.sty can provide a convenient interface for
% performing various operations on verbatim text. You don't even need
% to print out the argument! For greatest efficiency in such obscure
% applications, you can define a null url-style where all the lists like
% "\UrlBreaks" are empty.
