Visual Sequence Finding in Softanza

Core Features

1. Basic Finding

Let's start with searching for "haro" within a jumble of letters using the straightforward Find() method, which returns the list of positions where the sequence appears:

load "stzlib.ring"

o1 = new stzString("fjharoljharodjharog")
? @@( o1.Find("haro") )
#--> [ 3, 9, 15 ]

NOTE: The @@(val) function (resembling two glasses one puts on to improve sight) returns a readable, string-based representation of the value val, regardless of its type.

2. Visual Enhancement

We can add a visual dimension by using the viz prefix with Find(), making the positions easy to spot:

? o1.vizFind("haro")
#-->
# fjharoljharodjharog
# --^-----^-----^----

3. Enhanced Visual Output

To gain even more insight, we can add the XT() suffix, providing a :Numbered guide for each matched position:

? o1.vizFindXT("haro", [ :Numbered = TRUE ])
#-->
# fjharoljharodjharog
# --^-----^-----^----
#   3     9     15

NOTE: The XT() suffix, when appended to a Softanza function, signifies an eXTended outcome of the basic feature in question. In our case, it's about providing a list of options, such as [ :Numbered = TRUE ] above, and others that we will discover later.

4. Section Finding

The FindAsSections() method (or simply FindZZ()) offers a different perspective by returning each sequence position as a pair of start and end positions:

? @@( o1.FindAsSections("haro") ) # Or simply FindZZ()
#--> [ [3, 6], [9, 12], [15, 18] ]

NOTE: If you try FindZ() instead of FindZZ(), you'll see that both Z() and ZZ() return positions, but the first as numbers and the second as sections (pairs of numbers). Whatever your need, such smart yet powerful Softanza tiny suffixes, applied to almost any function, will have you covered!

5. Sectioned Visualization

The sections can be visualized using the :Sectioned option, which clearly shows the boundaries of each match:

? o1.vizFindXT("haro", [ :Sectioned = TRUE, :Numbered = TRUE ])
#-->
# fjharoljharodjharog
#   '--'  '--'  '--'
#   3  6  9 12  15 18

6. Full Structured Visualization

For the most sophisticated display, we can combine boxing, sectioning and numbering options to create a highly structured and detailed view:

? o1.vizFindXT("haro", [
	:Boxed = TRUE, 
	:Rounded = TRUE, 
	:Sectioned = TRUE, 
	:Numbered = TRUE 
])
#-->

          '-----------'           '-----------'           '-----------'
          3           6           9         12            15         18

NOTE: If you try :NumberedXT = TRUE instead of just :Numbered = TRUE, you'll see that the XT suffix forces the display of positions for all the characters, not just the sections defined, which can be useful in some cases.

Why It Matters

Technical Excellence

• Minimal design and execution overhead through a pure declarative experience
• Progressive visualization from basic positions to sectioned views
• Multiple representation options (positions, sections, visual markers, chars boxes)
• Flexible customization through combined options and smart defaults

Development Impact

1. Debugging: Instant visual identification of sequences and their boundaries
2. Analysis: Clear representation of sequence positions and sections
3. Documentation: Professional, readable output with multiple visualization options
4. Teaching: Intuitive demonstration of string concepts and sequence locations

Design Philosophy: The Visual Approach in Softanza

The sequence finding feature demonstrates Softanza's core design philosophy: transforming console output into meaningful visual representations. This approach:

• Makes Operations Visible: Each visualization carries clear meaning about the operation being performed - sections show boundaries, numbers provide precise positions, and box drawings create structure
• Leverages Console Power: Rich visual feedback without GUI libraries, using just ASCII and Unicode thoughtfully
• Sets a Pattern: The visual elements introduced here (markers, sections, boxes) establish a language that extends to other Softanza operations with lists, grids, and more

Conculsion

Softanza sequence finding solution showcases how console output can be both beautiful and deeply functional, making abstract algorithmic operations immediately understandable.
