Methods and systems for developing software can perform both compilation operations and read-evaluate-print-loop (REPL) operations on source code. In one embodiment, an integrated development environment can include a source code editor and a compiler and can perform the following operations: receiving source code and performing REPL operations as the source code is received; receiving edits in the source code for which REPL operations have been performed and compiling, by the compiler, the edited source code; and storing results of execution of the edited source code for use in subsequent REPL operations.

Items in a hierarchy may be displayed in an outline view, where each item at a hierarchy level is presented in a separate line, or as condensed hierarchy lines. A condensed hierarchy line displays two or more related items in a single line. Condensed hierarchy lines present the context of items in a hierarchy in reduced display area as compared with outline views. Users may add or remove items from condensed hierarchy lines using any type of input. Each portion of a condensed hierarchy line represents a different item at a different level of the hierarchy. Items in the condensed hierarchy line may include active user interface elements. Users or applications may define multiple condensed hierarchy lines as needed from arbitrary groups of items in adjacent hierarchy levels. Multiple condensed hierarchy lines can be used to show context for sibling relationships between items.

Condensing hierarchies in user interfaces

Empty elements or positions in an arrangement of data are hidden or revealed to present an overview of the relationships between empty and non-empty elements. Empty elements may be revealed at fractional increments of the interval between the two items. Additional empty elements may be revealed at smaller fractional increments of the intervals. Empty elements may be revealed at fixed increments within the interval between two items, with additional empty elements revealed at further multiples of this increment. Hierarchical arrangements of data may be unfolded or expanded to reveal additional empty or non-empty elements at further hierarchy levels. Similarly, nodes of arbitrary graphs that are empty, associated with a specified hierarchy level, and/or satisfy any other criteria may be automatically hidden and grouped with visible items. Hidden data may be revealed based on hierarchy level or a relative position with respect to one, two, or more visible items.

Unfolding sparse data sets

A display area displays a subset of a set of items. Items may be the ancestor or descendant of one or more other items. As an ancestor item having one or more visible descendant items becomes not visible, for example by scrolling outside the display area, a proxy in the display area is automatically created. The proxy corresponds with the ancestor item not visible in the display area. Multiple proxies may be displayed in the display area to present a complete view of the hierarchy containing at least some of the items visible in the display area. Items that do not have descendant items visible in the display area will not generate corresponding proxies when they become not visible. Proxies may be active user interface elements. Conversely, if an ancestor item becomes visible in the display area, any corresponding proxies are automatically removed.
