.el .SS "class2prefix( \f(CW$class\fP, \f(CW$case\fP );"

Returns home directory for given class.
.SS "dist_indicator_file_list"
.IX Subsection "dist_indicator_file_list"
Returns a list of files which can be tested to check if you're inside
a \s-1CPAN\s0 distribution which is not yet installed.
.PP

.SS "request($uri)"
.IX Subsection "request($uri)"
Returns an HTTP::Request object for a uri.
.SS "ensure_class_loaded($class_name, \e%opts)"
.IX Subsection "ensure_class_loaded($class_name, %opts)"
Loads the class unless it already has been loaded.
.PP
If \f(CW$opts\fR{ignore_loaded} is true always tries the require whether the package
already exists or not. Only pass this if you're either (a) sure you know the
file exists on disk or (b) have code to catch the file not found exception
that will result if it doesn't.
.ie n .SS "merge_hashes($hashref, $hashref)"
.el .SS "merge_hashes($hashref, \f(CW$hashref\fP)"
.IX Subsection "merge_hashes($hashref, $hashref)"
Base code to recursively merge two hashes together with right-hand precedence.
.ie n .SS "env_value($class, $key)"
.el .SS "env_value($class, \f(CW$key\fP)"
.IX Subsection "env_value($class, $key)"
Checks for and returns an environment value. For instance, if \f(CW$key\fR is
\&'home', then this method will check for and return the first value it finds,
looking at \f(CW$ENV\fR{\s-1MYAPP_HOME\s0} and \f(CW$ENV\fR{\s-1CATALYST_HOME\s0}.
.SS "term_width"
.IX Subsection "term_width"
Try to guess terminal width to use with formatting of debug output
.PP
All you need to get this work, is:
.PP
1) Install Term::Size::Any, or
.PP
2) Export \f(CW$COLUMNS\fR from your shell.
.PP
(Warning to bash users: 'echo \f(CW$COLUMNS\fR' may be showing you the bash
variable, not \f(CW$ENV\fR{\s-1COLUMNS\s0}. 'export COLUMNS=$COLUMNS' and you should see
that 'env' now lists \s-1COLUMNS\s0.)
.PP
As last resort, default value of 80 chars will be used.
.SS "resolve_namespace"
.IX Subsection "resolve_namespace"
Method which adds the namespace for plugins and actions.
.PP
.Vb 1
