.SYNOPSIS PsColors class provides methods to apply and remove colors from a screen content. .DESCRIPTION The PsColors class contains methods to apply and remove colors from a screen content. It also provides functionality to capture and apply a color map to a screen file. .NOTES Author: [Your Name] Date: [Current Date] #> class PsColors { [hashtable]$color PsColors() { $this.color = $this.GetColorMap() } <# .SYNOPSIS Retrieves the color map for PsColors class. .DESCRIPTION This method returns a hashtable containing the color map for PsColors class. The color map consists of color names as keys and their corresponding unicode and wildcard values as properties. .OUTPUTS hashtable A hashtable containing the color map. #> [hashtable] GetColorMap() { ##unicode of bright yellow ##$([char]0x1b)[33;1m $colorMap = @{ "red" = @{ "unicode" = "$([char]0x1b)[31m" "wildcard" = "\[\[red" } "black" = @{ "unicode" = "$([char]0x1b)[30m" "wildcard" = "\[\[black" } "green" = @{ "unicode" = "$([char]0x1b)[1;32m" "wildcard" = "\[\[green" } "yellow" = @{ "unicode" = "$([char]0x1b)[33;1m" "wildcard" = "\[\[yellow" } "bryellow" = @{ "unicode" = "$([char]0x1b)[33;1m" "wildcard" = "\[\[bryellow" } "blue" = @{ "unicode" = "$([char]0x1b)[34m" "wildcard" = "\[\[blue" } "gray" = @{ "unicode" = "$([char]0x1b)[2m" "wildcard" = "\[\[gray" } "magenta" = @{ "unicode" = "$([char]0x1b)[35m" "wildcard" = "\[\[magenta" } "cyan" = @{ "unicode" = "$([char]0x1b)[36m" "wildcard" = "\[\[cyan" } "brcyan" = @{ "unicode" = "$([char]0x1b)[96m" "wildcard" = "\[\[brcyan" } "white" = @{ "unicode" = "$([char]0x1b)[37m" "wildcard" = "\[\[white" } "brwhite" = @{ "unicode" = "$([char]0x1b)[1;97m" "wildcard" = "\[\[brwhite" } "bblack" = @{ "unicode" = "$([char]0x1b)[7m" "wildcard" = "\[\[bblack" } "bred" = @{ "unicode" = "$([char]0x1b)[41m" "wildcard" = "\[\[bred" } "bgreen" = @{ "unicode" = "$([char]0x1b)[42m" "wildcard" = "\[\[bgreen" } "byellow" = @{ "unicode" = "$([char]0x1b)[43m" "wildcard" = "\[\[byellow" } "bblue" = @{ "unicode" = "$([char]0x1b)[44m" "wildcard" = "\[\[bblue" } "bmagenta" = @{ "unicode" = "$([char]0x1b)[45m" "wildcard" = "\[\[bmagenta" } "bgcyan" = @{ "unicode" = "$([char]0x1b)[46m" "wildcard" = "\[\[bgcyan" } "bgwhite" = @{ "unicode" = "$([char]0x1b)[47m" "wildcard" = "\[\[bgwhite" } "reset" = @{ "unicode" = "$([char]0x1b)[0m" "wildcard" = "\[/" } } return $colorMap } <# .SYNOPSIS Applies the color map to the specified screen file. .DESCRIPTION This method reads the content of the screen file and applies the color map to it.
