Current File : //usr/share/zsh/4.3.11/functions/url-quote-magic
# Functions to make it easier to type URLs as command line arguments.  As
# you type, the input character is analyzed and, if it may need quoting,
# the current word is checked for a URI scheme.  If one is found and the
# current word is not already in quotes, a backslash is inserted before
# the input character.

# Setup:
#       autoload -Uz url-quote-magic
#       zle -N self-insert url-quote-magic

# A number of zstyles may be set to control the quoting behavior.
#
# url-metas
#  This style is looked up in the context :url-quote-magic:SCHEME (where
#  SCHEME is that of the current URL, e.g. "ftp").  The value is a string
#  listing the characters to be treated as globbing metacharacters when
#  appearing in a URL using that scheme.  The default is to quote all zsh
#  extended globbing characters, excluding '<' and '>' but including
#  braces (as in brace expansion).  See also url-seps.
#
# url-seps
#  Like url-metas, but lists characters that should be considered command
#  separators, redirections, history references, etc.  The default is to
#  quote the standard set of shell separators, excluding those that
#  overlap with the extended globbing characters, but including '<' and
#  '>' and the first character of $histchars.
#
# url-globbers
#  This style is looked up in the context :url-quote-magic.  The values
#  form a list of command names that are expected to do their own globbing
#  on the URL string.  This implies that they are aliased to use the
#  "noglob" modifier.  When the first word on the line matches one of the
#  values AND the URL refers to a local file (see url-local-schema), only
#  the url-seps characters are quoted; the url-metas are left alone,
#  allowing them to affect command-line parsing, completion, etc.  The
#  default values are a literal "noglob" plus (when the zsh/parameter
#  module is available) any commands aliased to the helper function
#  "urlglobber" or its alias "globurl".
#
# url-local-schema
#  This style is always looked up in the context :urlglobber, even though
#  it is used by both url-quote-magic and urlglobber.  The values form
#  a list of URI schema that should be treated as referring to local files
#  by their real local path names, as opposed to files which are specified
#  relative to a web-server-defined document root.  The defaults are "ftp"
#  and "file".
#
# url-other-schema
#  Like url-local-schema, but lists all other URI schema upon which
#  urlglobber and url-quote-magic should act.  If the URI on the
#  command line does not have a scheme appearing either in this list or in
#  url-local-schema, it is not magically quoted.  The default values are
#  "http", "https", and "ftp".  When a scheme appears both here and in
#  url-local-schema, it is quoted differently depending on whether the
#  command name appears in url-globbers.

# TODO:
#	Add a style for "document root" for globbing local URLs.
#	Turn this on at colon, and off again at space or accept.
#       Use compsys for nested quoting analysis and command parsing.

# Establish default values for styles, but only if not already set
