Still writing and ironing out the default core display functions.
This includes reducing code that was written (at least) twice and could be 'combined' to a single function.

But mostly - as for optimizing code - I try to find a proper way around the the injection protection and 'bold' or colored strings that one might want to use/display.
At the very least so that the function title prints bold text.

The injection protection is not based on my skillset, however, I can read a case and some basic regex so I saw/knew that the console code for 'bold' causes an 'issue', which it did.

Next on my wish todolist is pick and cfg.set.
And I also need to finish bol2str in order to start with swarm.
I need to get the (basic, at least) swarm function done before the config editor - just so I can start scripting other things properly, and do 'external end-user' testing and so I can keep the code cleaner.
Also that will help to keep motivation up.

Current question...
However, for my current task at hand, the read wrappers, yesno, pick and input were, well - still are, based on the physicaly installed read I had to actualy parse the --help output of it to get its functionality to get them work poperly (for TUI).
Now for SWARM I'd like to reduce physical disk usage (files) to a minimum (for non-log actions; setting).

This and the recent Heureka that there's a builtin read, made me hope that the bash builtin read might have the same functions across all distros - as long the propper BASH version is installed, which would simplify the 'wrapping' process.... alot...

How to provide help?
Also the 'help' functionality of SWARM is slowly evolving in my head.
Main challenge here is that I want to distinct functions (for the help usage) between 'basics' and 'advanced', while keep most of it 'dynamic' to use - yet simple for translating.
Because I dont WANT to write actual help text for functions, because to get those, you would need to source SWARM and then call the function with --help, which seems 'too much' for me.

So I'd rather write/modify the (former) manpages and write a handler to work like:

Code:

./SWARM/runtime help [topic]

So you can 'stay' in your current project but still get the information you need.

That's for now, have a nice weekend and stay healthy everyone!

Alzabo::Runtime::InsertHandle(3pm)			User Contributed Perl Documentation			Alzabo::Runtime::InsertHandle(3pm)

NAME

       Alzabo::Runtime::InsertHandle - A handle representing an insert

SYNOPSIS

	my $handle =
	    $table->insert_handle
		( columns => [ $table->columns( 'name', 'job' ) ] );

	my $faye_row =
	    $handle->insert( values =>
			     { name => 'Faye',
			       job => 'HK Pop Chanteuse' } );

	my $guesch_row =
	    $handle->insert( values =>
			     { name => 'Guesch',
			       job => 'French Chanteuse and Dancer' } );

DESCRIPTION

       This object is analogous to a DBI statement handle, and can be used to insert multiple rows into a table more efficiently than repeatedly
       calling "Alzabo::Runtime::Table->insert()".

METHODS

       Objects of this class provide one public method:

       insert

       This method is used to insert a new row into a table.

       It accepts the following parameters:

       * values
	   This should be a hash reference containing the values to be inserted into the table.

	   If no value is given for a primary key column and the column is "sequenced" then the primary key will be auto-generated.

	   If values are not provided for other columns which were given when "Alzabo::Runtime::Table->insert_handle" was called, this method
	   first checks to see if a value was provided for the column when "Alzabo::Runtime::Table->insert_handle" was called.	If none was pro-
	   vided, then the column's default value is used.

	   If column values were passed to "Alzabo::Runtime::Table->insert_handle", then these can be overridden by values passed to this method.

	   It is not possible to override column values that were given as SQL functions when "Alzabo::Runtime::Table->insert_handle" was called.

       This method returns a new "Alzabo::Runtime::Row" object.

       Throws: "Alzabo::Exception::Logic", "Alzabo::Exception::Params"
