Text::ANSITable Question

vishi has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I'm using the Text::ANSITable module to create a table and populate it with some values. I'm using the Page here

http://search.cpan.org/~perlancar/Text-ANSITable-0.39/lib/Text/ANSITable.pm

to understand how the module works. However, I'm having a tough time understanding the section "Environment". Where and how I use this to set my options is quite confusing to me. I'm not very familiar with this setting. Can anyone help me understand how I should use this and the options in the Environment section in my code?

the docs refer to Environment variable. Such variables are an OS thing. Perl lets you to access and modify them via the special variable `%ENV` as explained in perlvar. The module has many defaults that can be set via environment variables or directly. HtH L* There are no rules, there are no thumbs..

Environment variables can be set in a number of ways. However, a quick skim seems to show that in Text::ANSITable, the environment variables are simply default values for the attributes that you'd normally set via the constructor. Do you really need to do that? e.g. in Perl, `$ENV{ENVIRONMENT_VARIABLE_NAME} = "value";`, in a *NIX shell usually (depending on the shell) something like `export ENVIRONMENT_VARIABLE_NAME=value` or on a per command basis like `ENVIRONMENT_VARIABLE_NAME=value perl script.pl`	[reply] [d/l] [select]

You export these variables in the shell before starting perl, like so: `$ export ANSITABLE_STYLE_SETS='[["AltRow",{"odd_bgcolor":"003300"}]]' $ perl my_ansitable_script.pl` [download]	[reply] [d/l]
