ProfileExtensions.ps1
########################################
#
# ProfileExtensions.ps1
#
# The profile extensions is normally called by a single line that is added to
# the end of $Profile, or can be dotsourced manually if required.
#
# The handler line in $Profile performs the following:
# a) It check if $($Profile)_extensions.ps1 exists, if not download it.
# b) It then runs (dotsource) $($Profile)_extensionss.ps1.
#
# Core Notes:
# Do not inject notifications into the console at start time as remember that
# this will be called when all scripts run. Make sure that these extensions always
# have a less than one second load time, anything more complex should be pushed
# into the Custom-Tools.psm1 Module. Make sure to note the switches to use when
# running scripts, to save on memory overheads:
# -NoProfile -NoLogo (see about_PowerShell.exe)
# Do not migrate gist-functions into custom-tools as they are dependent upon my
# specific GitHub account access, have to keep things generic.
#
# Using the handler line in $Profile allows keeping this set of tools completely
# separate from $Profile so that it can be replaced / updated at any time and
# disabling it is as simple as removing the single line that calls the extensions.
#
# Intent is to only keep core console functionality functions in here that relate
# to these tools (so things like Update-ProfileExtensions would go here) and then
# putting other more complex tools into the Custom-Tools.psm1 Module.

# https://stackoverflow.com/questions/26008148/convert-a-hashtable-to-a-string-of-key-value-pairs
# To join things into a string, can either concatenate with a separator then strip the trailing separator character
# I normally do it in a clunky way of combining then trimming, which is fine, but there are better ways
### Method 1: Using the OFS (Output Field Separator)
# $myhash = @{"foo"=4;"bar"=5}
# $OFS =';'
# [string]($myhash.GetEnumerator() | % { "$($_.Key)=$($_.Value)" }) # OFS will automatically apply as separator!
### Method 2: Using Join (this is probably clearer/better)
# $myhash = @{"foo"=4;"bar"=5}
# ($myhash.GetEnumerator() | % { "$($_.Key)=$($_.Value)" }) -join ';'
### Method 3: foreach then trim the last character (this is how I would normally do this)
# $myhash = @{"foo"=4;"bar"=5}
