in the Windows on Pry the Auto indent and color feature is not turned on by default.

Need to be configured.

PryConfiguration

put it in the personal directory. PRYRC in the file ( file path :%userprofile%\. PRYRC).

Configuration file does not exist by default, you need to create a new one, enter it inside

Pry.config.color=true

Pry.config.auto_indent=true

Pry.config.correct_indent = True

# change the color of some keywords, first get Coderay in the module terminal.rb the keywords and colors Map ,

# If you use the Pry-theme , then this modification is useless and needs to be modified. Pry-theme the configuration file : ~\.pry\themes\xx

if! (Prytheme::version rescue Nil)

# if not installed Pry-theme

#p "Not install Pry-theme"

#CodeRay. Scan ("Example",: Ruby). Term

# Just to load necessary files

My_token_colors = Nil

if (coderay::encoders::terminal::token_colors rescue nil)

# Coderay 1.0.0

My_token_colors = Coderay::encoders::terminal::token_colors

Else

# Coderay 0.9

Begin

Require ' coderay/encoders/term '

My_token_colors = Coderay::encoders::term::token_colors

Rescue = E

End

End

If my_token_colors

my_token_colors[:d efinition] = "1;30″

My_token_colors[:string][:modifier] = "1;30″

my_token_colors[:string][:d Elimiter] = "1;30″

My_token_colors[:symbol] = "1;30″

#p coderay::encoders::term::token_colors ,

End

End

The configuration content has a code that modifies the color of the keyword because the Windows on those bright green color display errors, resulting in the content is not visible, so I added the code modified, will be bright green (Bright_green) colors are changed to other colors.

now run at Terminal Pry , there is color in the output.

In addition, if you need to Pry to see the help, you need to install Pry-doc .
