Migrating from Color.jl

Colors.jl was forked from an original repository called Color.jl created by Daniel Jones.

The following script can be helpful if you intending to migrate from Color.jl to Colors.jl.

# Intended to be run from the top directory in a package
# Do not run this twice on the same source tree without discarding
# the first set of changes.
sed -i 's/\bColor\b/Colors/g' REQUIRE

fls=$(find . -name "*.jl")
sed -i 's/\bColor\b/Colors/g' $fls               # Color -> Colors
sed -i -r 's/\bcolor\("(.*?)"\)/colorant\"\1\"/g' $fls   # color("red") -> colorant"red"
sed -i 's/AbstractAlphaColorValue/TransparentColor/g' $fls
sed -i 's/AlphaColorValue/TransparentColor/g' $fls   # might mean ColorAlpha
sed -i 's/ColorValue/Color/g' $fls
sed -i 's/ColourValue/Color/g' $fls
sed -i -r 's/\bLAB\b/Lab/g' $fls
sed -i -r 's/\bLUV\b/Luv/g' $fls
sed -i -r 's/\b([a-zA-Z0-9_\.]+)\.c\.(\w)\b/\1\.\2/g' $fls      # colval.c.r -> colval.c
# This next one is quite dangerous, esp. for LCHab types...
# ...on the other hand, git diff is nice about showing the things we should fix
sed -i -r 's/\b([a-zA-Z0-9_\.]+)\.c\b/color(\1)/g' $fls

# These are not essential, but they generalize to RGB24 better
# However, they are too error-prone to use by default since other color
# types like Lab have fields with the same names
#sed -i -r 's/\b([a-zA-Z0-9_\.]+)\.r\b/red(\1)/g' $fls          # c.r -> red(c)
#sed -i -r 's/\b([a-zA-Z0-9_\.]+)\.g\b/green(\1)/g' $fls
#sed -i -r 's/\b([a-zA-Z0-9_\.]+)\.b\b/blue(\1)/g' $fls
#sed -i -r 's/\b([a-zA-Z0-9_\.]+)\.alpha\b/alpha(\1)/g' $fls     # c.alpha -> alpha(c)

You are strongly advised to check the results carefully; for example, any object obj with a field named c will get converted from obj.c to color(obj), and if obj is not a Colorant this is surely not what you want. You can use git add -p to review/edit each change individually.
