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 -% "{". 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 should 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. -% -% Defining a defined-url: -% Take for example the email address "myself%node@gateway.net" 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%node@gateway.net} or -% \urldef{\myself}\url|myself%node@gateway.net| -% and then you may use "\myself" instead of "\url{myself%node@gateway.net}" -% 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 tt and email addresses to be rm, then you would define new url-like -% commands as follows: -% -% \newcommand\email{\begingroup \urlstyle{rm}\Url} -% \newcommand\directory{\begingroup \urlstyle{tt}\Url} -% -% You must follow this format closely, and NOTE that the final command is -% "\Url", not "\url". 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 -% \newcommand\url{\begingroup \Url} -% I.e., using whatever url-style has been selected. -% -% You can make a defined-url for these other styles, using the usual -% "\urldef" command as in this example: -% -% \urldef{\myself}{\email}{myself%node.domain@gateway.net} -% -% which makes "\myself" act like "\email{myself%node.domain@gateway.net}", -% if the "\email" command is defined as above. The "\myself" command is -% 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}". -% In addition to setting "\UrlFont", some characters will probably need -% to be defined in the "\UrlSpecials" list because most fonts don't have -% all the standard input characters. See the definition of "\url@rmstyle", -% which implements "\urlstyle{rm}". Or even better, follow the definition -% of "\url@sfstyle", which executes "\url@rmstyle" and then redefines -% just "\UrlFont". The nominal format for each special character "c" -% in the "\UrlSpecials" list is: "\do\c{}", but you can -% include other definitions too. -% -% 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' 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 to handle -% several characters that are not present in fonts. -% -% 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". -% -% Yet more flexibility: -% You can also set up url.sty to do multiple things with the verbatim text -% by defining "\Url@use", but the format of the definition is special: -% -% \def\Url@use#1\,{ ... do things with #1 ... } -% -% Yes, that is "#1" followed by "\," then the definition. For example, -% to put a hypertext link in the DVI file: -% -% \def\Url@use#1\,{\special{html:}#1\special{html:}} -% -% The End -% ver 1.1 6-Feb-1996: -% Fix hyphens that wouldn't break and ligatures that weren't suppressed. - -Test file integrity: ASCII 32-57, 58-126: !"#$%&'()*+,-./0123456789 -:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~
