-# chpwd_profiles(): Directory Profiles
+# chpwd_profiles(): Directory Profiles, Quickstart:
#
-# Say you want certain settings to be active in certain directories. This is
-# what you want.
+# In .zshrc.local:
#
-# To get it working you will need this function and something along the
-# following lines:
-#
-# chpwd_functions+=( chpwd_profiles )
+# zstyle ':chpwd:profiles:/usr/src/grml(|/|/*)' profile grml
+# zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
# chpwd_profiles
#
-# You will usually want to do that *after* you configured the system. That
-# configuration is described below.
-#
-# zstyle ':chpwd:profiles:/usr/src/grml(|/|/*)' profile grml
-# zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
-#
-# When that's done and you enter a directory that matches the pattern in the
-# third part of the context, a function called chpwd_profile_grml, for example,
-# is called (if it exists).
-#
-# If no pattern patches (read: no profile is detected) the profile is set to
-# 'default', which means chpwd_profile_default is attempted to be called.
-#
-# A word about the context (the ':chpwd:profiles:*' stuff in the zstyle
-# command) which is used: The third part in the context is matched against
-# ${PWD}. That's why using a pattern such as /foo/bar(|/|/*) makes sense.
-# Because that way the profile is detected for all these values of ${PWD}:
-# /foo/bar
-# /foo/bar/
-# /foo/bar/baz
-# So, if you want to make double damn sure a profile works in /foo/bar and
-# everywhere deeper in that tree, just use (|/|/*) and be happy.
-#
-# The name of the detected profile will be available in a variable called
-# 'profile' in your functions. You don't need to do anything, it'll just be
-# there.
-#
-# Then there is the parameter $CHPWD_PROFILE is set to the profile, that was is
-# currently active (the default value is "default"). That way you can avoid
-# running code for a profile that is already active, by running code such as
-# the following at the start of your function:
-#
-# function chpwd_profile_grml() {
-# [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
-# ...
-# }
-#
-# If you know you are going to do that all the time for each and every
-# directory-profile function you are ever going to write, you may also set the
-# `re-execute' style to `false' (which only defaults to `true' for backwards
-# compatibility), like this:
-#
-# zstyle ':chpwd:profiles:*' re-execute false
-#
-# If you use this feature and need to know whether it is active in your current
-# shell, there are several ways to do that. Here are two simple ways:
-#
-# a) If knowing if the profiles feature is active when zsh starts is good
-# enough for you, you can use the following snippet:
-#
-# (( ${+functions[chpwd_profiles]} )) && print "directory profiles active"
-#
-# b) If that is not good enough, and you would prefer to be notified whenever a
-# profile changes, you can solve that by making sure you start *every*
-# profile function you create like this:
-#
-# function chpwd_profile_myprofilename() {
-# [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
-# print "chpwd(): Switching to profile: $profile"
-# ...
-# }
-#
-# That makes sure you only get notified if a profile is *changed*, not
-# everytime you change directory. (To avoid this, you may also set the newer
-# `re-execute' style like described further above instead of the test on top of
-# the function.
-#
-# If you need to do initialisations the first time `chpwd_profiles' is called
-# (which should be in your configuration file), you can do that in a function
-# called "chpwd_profiles_init". That function needs to be defined *before*
-# `chpwd_profiles' is called for this to work.
-#
-# During the *first* call of `chpwd_profiles' (and therefore all its profile
-# functions) the parameter `$CHPWD_PROFILES_INIT' exists and is set to `1'. In
-# all other cases, the parameter does not exist at all.
-#
-# When the system switches from one profile to another, it executes a function
-# named "chpwd_leave_profile_<PREVIOUS-PROFILE-NAME>()" before calling the
-# profile-function for the new profile.
-#
-# There you go. Now have fun with that.
-#
-# Note: This feature requires zsh 4.3.3 or newer.
+# For details see the `grmlzshrc.5' manual page.
