(Newbie) perldoc ESC display trouble

(Newbie) perldoc ESC display trouble

[Richard Jolly]

Hi,

I've recently switched to zsh on cygwin. I get display trouble in the form of expanded escape characters, ie ESC[1m Some Text [0m, when using perldoc.

For example:

> perldoc Getopt::Long
Getopt::Long(3)       User Contributed Perl Documentation      Getopt::Long(3)



ESC[1mNAMEESC[0m
       Getopt::Long - Extended processing of command line options

ESC[1mSYNOPSISESC[0m


The escaped sections should be dispalyed as bold.

Any suggestions, pointers to documentation, etc, very welcome,

TIA,

Richard

maybe you should check the value of the TERM variable? Don't know if
cygwin uses that though. Maybe the current TERM cannot handle the 
escape sequences?

I had the same problem (with bash on Linux), I gave up and now i'm
just exporting PERLDOC=-t with which everything is just in plain text,

Perldoc is running "less", which defaults to displaying the control
characters visibly.  It needs the -R option to allow it to display ANSI
control sequences directly to the terminal.  You can type the option
after perldoc/less is running to test that this fixes the problem for
you, and then set it in your environment in your .zshrc (and set a few
other options while you're at it) for a permanent solution:

    export LESS=mqeisz-2XR

Thanks - this works perfectly. I like the window scrolling adjustment as well.

Much appreciated,

Richard
