xresources2putty is a small utility which takes an Xresources file and converts it into a Windows registery file which changes the theme (colors) of one or more PuTTY sessions.
Edit config.mk if needed.
Build the software:
Build with debug symbols:
$ make debug
Regenerate literal colors.h:
$ make literal_colors
Using the XTerm class and $HOME/.Xdefaults, for PuTTY sessions "default" and "server":
$ xresources2putty -class XTerm -sessions default,server $HOME/.Xdefaults
xresources2putty will output the registery file to standard output, so it's wise to redirect the output:
$ xresources2putty -class XTerm -sessions default,server $HOME/.Xdefaults > putty_colors.reg
Then copy the file to your Windows box of choice and import it, by either double clicking it in Explorer, or use regedit.
