Opusmodus 4.0.30671 (Update)

Additional Ncode functionality (Ncode Manual):

2.2.4 SETF mode, templates, and pages

NCODE provides a template-driven mode for constructing structured values via SETF pages. This mode is used when the Function field is SETF and a template is selected. Rather than entering a single expression, the user fills a set of pages; NCODE then reconstructs a quoted value and evaluates a (setf …) form.

Figure 3 SETF mode, templates and pages.

SETF pages provide a UI method for building complex, repeatable list structures (collections of labelled items) without manual list syntax. This is particularly useful when the value is naturally expressed as multiple items that must be ordered.

Templates

A template defines:

• the number and organisation of pages, and

• the fields available on each page (key–value pairs).

Selecting a different template changes the page layout and the meaning of the fields. The selected template and page contents are saved in the .omnc session and restored when reopened.

Each page corresponds to one logical item in the resulting value.

• Next page creates a new item.

• Remove page removes an item.

Empty pages are ignored when the final value is constructed.

Field values

• Fields accept numbers, strings, keywords, lists, and symbols.

• Symbols entered without a leading quote may be treated as variable references (for example, previously stored history variables).

• When a literal symbol is required, enter it as a quoted symbol.

Constructed value

When evaluated, NCODE converts the populated pages into a single quoted form:

• if one page is populated, the value becomes a quoted single item;

• if multiple pages are populated, the value becomes a quoted list of items.

NCODE then evaluates the corresponding (setf …) form, storing the result in the history like any other entry.

Reproducibility

SETF pages are stored as structured page data in the session. When reloading a session or using Refresh All, NCODE reconstructs the same quoted value from the saved pages and re-establishes consistent bindings.

NCODE is still in beta, but with every update, it is becoming a more stable tool.
