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 -U 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 + +zstyle -m ':url-quote-magic:\*' url-metas '*' || + zstyle ':url-quote-magic:*' url-metas '*?[]^(|)~#{}=' + +zstyle -m ':url-quote-magic:\*' url-seps '*' || + zstyle -e ':url-quote-magic:*' url-seps 'reply=(";&<>${histchars[1]}")' + +zstyle -m :url-quote-magic url-globbers '*' || + zstyle -e :url-quote-magic url-globbers \ + 'zmodload -i zsh/parameter; + reply=( noglob + ${(k)galiases[(R)(* |)(noglob|urlglobber|globurl) *]:-} + ${(k)aliases[(R)(* |)(noglob|urlglobber|globurl) *]:-} )' + +zstyle -m ':urlglobber' url-local-schema '*' || + zstyle ':urlglobber' url-local-schema ftp file + +zstyle -m ':urlglobber' url-other-schema '*' || + zstyle ':urlglobber' url-other-schema http https ftp + +# Define the "urlglobber" helper function and shorthand "globurl" alias + +function urlglobber { + local -a args globbed localschema otherschema + local arg command="$1" + shift + zstyle -s :urlglobber url-local-schema localschema '|' + zstyle -s :urlglobber url-other-schema otherschema '|' + for arg + do + case "${arg}" in + ((${~localschema}):/(|/localhost)/*) + globbed=( ${~${arg##ftp://(localhost|)}} ) + args[$#args+1]=( "${(M)arg##(${~localchema})://(localhost|)}${(@)^globbed}" ) + ;; + ((${~otherschema}):*) args[${#args}+1]="$arg";; + (*) args[${#args}+1]=( ${~arg} );; + esac + done + "$command" "${(@)args}" +} +alias globurl='noglob urlglobber ' + +# Finally, define (and execute if necessary) the function we really want + +function url-quote-magic { + setopt localoptions noksharrays extendedglob + local qkey="${(q)KEYS}" + if [[ "$KEYS" != "$qkey" ]] + then + local lbuf="$LBUFFER$qkey" + if [[ "${(Q)LBUFFER}$KEYS" == "${(Q)lbuf}" ]] + then + local -a words + words=("${(@Q)${(z)lbuf}}") + local urlseps urlmetas urlglobbers localschema otherschema + if [[ "$words[-1]" == (#b)([^:]##):* ]] + then + zstyle -s ":url-quote-magic:$match[1]" url-seps urlseps '' + zstyle -s ":url-quote-magic:$match[1]" url-metas urlmetas '' + fi + zstyle -s :url-quote-magic url-globbers urlglobbers '|' + zstyle -s :urlglobber url-other-schema otherschema '|' + if [[ "$words[1]" == ${~urlglobbers} ]] + then + zstyle -s :urlglobber url-local-schema localschema '|' + else + localschema=' ' + fi + case "$words[-1]" in + (*[\'\"]*) ;; + ((${~localschema}):/(|/localhost)/*) + [[ "$urlseps" == *"$KEYS"* ]] && + LBUFFER="$LBUFFER\\" ;; + ((${~otherschema}):*) + [[ "$urlseps$urlmetas" == *"$KEYS"* ]] && + LBUFFER="$LBUFFER\\" ;; + esac + fi + fi + zle .self-insert +} + +# Handle zsh autoloading conventions + +[[ -o kshautoload ]] || url-quote-magic "$@" |
