# PATH Helpers
#
# A few useful functions to manipulate the PATH environment variable. Use,
# modify, copy, steal, plunder these functions to your hearts content, at
# your own risk of course :) --jimeh
#
# Print PATH as a newline separated list.
#
# Example:
#
# $ echo $PATH
# /usr/bin:/usr/local/bin
# $ path_list
# /usr/bin
# /usr/local/bin
#
path_list () {
echo -e ${PATH//:/\\n}
}
# Append specified path to the end of PATH.
#
# Takes one argument:
# - $1: path to add
#
# If $1 already exists it is first removed, and then added to the end of PATH.
#
# Example:
#
# $ echo $PATH
# /usr/bin:/usr/local/bin
# $ path_append "/usr/sbin"
# $ echo $PATH
# /usr/bin:/usr/local/bin:/usr/sbin
#
path_append () {
if [ ! -n "$1" ]; then return 2; fi
path_remove $1
export PATH="$PATH:$1"
}
# Prepend specified path to the begnning of PATH.
#
# Takes one argument:
# - $1: path to add
#
# If $1 already exists it is first removed, and then added to the beginning of
# PATH.
#
# Example:
#
# $ echo $PATH
# /usr/bin:/usr/local/bin
# $ path_prepend "/usr/sbin"
# $ echo $PATH
# /usr/sbin:/usr/bin:/usr/local/bin
#
path_prepend () {
if [ ! -n "$1" ]; then return 2; fi
path_remove $1
export PATH="$1:$PATH"
}
# Remove specified path from PATH.
#
# Takes one argument:
# - $1: path to remove
#
# Example:
#
# $ echo $PATH
# /usr/bin:/usr/local/bin
# $ path_remove "/usr/local/bin"
# $ echo $PATH
# /usr/bin
#

# Add a path to PATH before another path.
#
# Takes two arguments:
# - $1: path to add
# - $2: target path to add $1 before
#
# If $1 already exists in PATH it is first removed, and then added before $2.
#
# Example:
#
# $ echo $PATH
# /usr/bin:/usr/local/bin
# $ path_add_before "/usr/local/sbin" "/usr/local/bin"
# $ echo $PATH
# /usr/bin:/usr/local/sbin:/usr/local/bin

# Add a path to PATH after another path.
#
# Takes two arguments:
# - $1: path to add
# - $2: target path to add $1 after
#
# If $1 already exists in PATH it is first removed, and then added after $2.
#
# Example:
#
# $ echo $PATH
# /usr/bin:/usr/local/bin
# $ path_add_after "/usr/local/sbin" "/usr/local/bin"
# $ echo $PATH
# /usr/bin:/usr/local/bin:/usr/local/sbin

# Strips first and last character from intput string.

# Example:
# $ __path_clean ":/bin:/usr/bin:"
# /bin:/usr/bin
#
