These are provided on many systems with the Multimedia +Internet Mail Extensions. + +To enable the system, the function tt(zsh-mime-setup) should be +autoloaded and run. This allows files with extensions to be treated +as executable; such files be completed by the function completion system. +The function tt(zsh-mime-handler) should not need to be called by the +user. + +The system works by setting up suffix aliases with `tt(alias -s)'. +Suffix aliases already installed by the user will not be overwritten. + +Repeated calls to tt(zsh-mime-setup) do not override the existing +mapping between suffixes and executable files unless the option tt(-f) +is given. Note, however, that this does not override existing suffix +aliases assigned to handlers other than tt(zsh-mime-handler). +Calling tt(zsh-mime-setup) with the option tt(-l) lists the existing +mapping without altering it. Calling tt(zsh-mime-setup) with the option +tt(-v) causes verbose output to be shown during the setup operation. + +The system respects the tt(mailcap) flags tt(needsterminal) and +tt(copiousoutput), see manref(mailcap)(4). + +The functions use the following styles, which are defined with the +tt(zstyle) builtin command (\ +ifzman(see zmanref(zshmodules))\ +ifnzman(noderef(The zsh/zutil Module))). They should be defined +before tt(zsh-mime-setup) is run.

Note in particular the `tt(.)' and trailing colon +to distinguish this use of the context. This overrides any handler +specified by the tt(mailcap) files. If the handler requires a terminal, +the tt(flags) style should be set to include the word tt(needsterminal), +or if the output is to be displayed through a pager (but not if the +handler is itself a pager), it should include tt(copiousoutput). +) +item(flags)( +Defines flags to go with a handler; the context is as for the +tt(handler) style, and the format is as for the flags in tt(mailcap). +) +item(pager)( +If set, will be used instead of tt($PAGER) or tt(more) to handle +suffixes where the tt(copiousoutput) flag is set.

Running +tt(zsh-mime-setup -l) will show the handler and, if there are any, the +flags. A tt(%s) in the handler is replaced by the file (suitably quoted +if necessary). Check that the handler program listed lists and can +be run in the way shown. Also check that the flags tt(needsterminal) or +tt(copiousoutput) are set if the handler needs to be run under a +terminal; the second flag is used if the output should be sent to a pager. +An example of a suitable tt(mailcap) entry for such a program is: + +example(text/html; /usr/bin/lynx '%s'; needsterminal) +) +endeit() +) +item(tt(pick-web-browser))( +This function is separate from the two MIME functions described above +and can be assigned directly to a suffix: + +example(autoload -U pick-web-browser +alias -s html=pick-web-browser) + +It is provided as an intelligent front end to dispatch a web browser. +It will check if an X Windows display is available, and if so +if there is already a browser running which can accept a remote +connection.
