A deterministic, reactive, math-driven document system with a visual page-layout editor and an pdf-style document reader. Documents are saved as .syn files — a hybrid markup format where layout, logic, and styling coexist in one file. Styling is always embedded; there is no separate .strss file.
- Syntaxia & Structura is a hybrid markup/programming language combining HTML-like structure with Python-style semantics and C-style operators.
.syn files are self-contained — layout, logic, and styling are all embedded.
- Mandatory HTML-like tags for all code blocks
- Python-style indentation for internal blocks
- C-style operators:
+,-,*,/,%,==,!=,<,>,<=,>=,&,&&,|,||,! - Math symbols:
π(Pi),√(square root) - Explicit type conversion:
<>target_type==source_value<> - Script references/imports:
<@>other_script.syn</@>

Features
- Physical page canvas — A4, A3, A5, Letter, Legal, Tabloid
- Draw text boxes by clicking and dragging on any page
- Select tool — click to select, drag to move, right-click or Delete to remove
- Multi-page support — add and delete pages from the left panel
- Properties panel — text content, font size, alignment (L/C/R), text colour, background colour, variable binding
- HSV colour wheel picker with live hex
#RRGGBBinput - Zoom (
Ctrl+scrollor toolbar buttons), fit-to-page - Saves and opens
.synfiles - Shortcuts:

Features
- Opens with a file picker if launched without arguments
- Drag a
.synfile directly onto the window - Pages rendered as physical white sheets on a dark slate background
- Handles both StructArch layout format and modern Structura document format
- Modern format (headings, paragraphs, tables, math blocks) is automatically reflowed onto pages
- Zoom and scroll;
◀ ▶page navigation;Home/Endkeys jump to first/last page - Status bar shows document title, author, page count, and current zoom
