Formula files and entries

Formula files are plain text files with the extensions .ufm (fractal formula files), .ucl (coloring 

algorithm files), or .uxf (transformation files). A formula file can contain any number of formulas 

(called entries).

Each entry starts with an entry identifier, followed by the contents of the entry between curly 

brackets { and }. After the entry identifier, an optional value between parentheses can be added. 

Examples:

My Formula {

; entry contents

}

Mandelbrot(XAXIS) {

; this formula uses an optional setting 

}

The entry identifier may consist of almost all characters, except spaces and tabs, of course. Since 

you can specify an additional descriptive title for the formula, the identifier can be cryptic as the user 

never notices it (but it is shown by the 

browser

). The identifier is used to distinguish between 

formulas in the same file, so no two formulas in the same file can have the same identifier.

The semicolon ; is used to add comments to a formula. After a semicolon, the rest of the line is 

ignored by the compiler. You can also add global comments like copyright information to a file by 

placing them inside a special comments { } entry, which is also ignored (but the browser shows it 

when the file is selected).

To facilitate working with entries, the built in formula editor can automatically create new entries and 

search for existing entries. See
