Full Discussion: Bash conditional prompt?

I am afraid that the answers given are not correct. There is a major difference between
conditional content in the prompt
and
conditional logic in the script that sets that prompt

The answer given by Corona688 seems to be the only one related.

Devel::Cover::Truth_Table(3)				User Contributed Perl Documentation			      Devel::Cover::Truth_Table(3)

NAME
Devel::Cover::Truth_Table - Truth tables for coverage objects. VERSION
version 1.03 SYNOPSIS
use Devel::Cover::Truth_Table; # $a || $b my $or_tt = Devel::Cover::Truth_Table->new_primitive('or_3', 0, 1, 1); # $c && $d my $and_tt = Devel::Cover::Truth_Table->new_primitive('and_3', 1, 0, 1); # merge contents of $and_tt into right column of $or_tt, to create # $a || ($c && $d) $or_tt->right_merge($and_tt); # get a (sorted) textual representation my @text = $or_tt->sort->text; print "$_ " foreach @text; __END__ A B C |exp|hit -------------- 0 0 X | 0 |--- 0 1 0 | 0 |--- 0 1 1 | 1 |+++ 1 X X | 1 |+++ -------------- DESCRIPTION
This module provides methods for creating and merging conditional primitives ("$a && $b", "$c || $d", etc.) into more complex composite expressions. METHODS
new_primitive($op, @coverage) Create a new truth table based on one of the built-in primitives, which are the subclasses of Devel::Cover::DB::Condition. $op is one of the following: and_3 "and" or "&&" with three conditional paths. or_3 "or" or "||" with three conditional paths. or_2 "or" or "||" with two conditional paths. (i.e., when the right hand side of the expression is a constant) xor_4 "xor" with four conditional paths. @coverage is a list booleans identifying which of the possible paths have been covered. sort() Sorts a truth table (in place) and returns the sorted object. text() Format a truth table to an array of strings for printing. html() Format a truth table in HTML. error() percentage() Determines the proportion of possible conditions that have coverage. right_merge($sub_table) Merge entries from $sub_table into right column of table. left_merge($sub_table) Merge entries from $sub_table into left column of table.
