- General
- Highlight between matching parens -- If checked, the
editor marks the region between matching parenthesis with a gray
background (in color) or a stipple pattern (in monochrome) when
the flashing caret is next to a parenthesis.
- Correct parens -- If checked, the editor automatically
converts a typed ``)'' to ``]'' to match ``['', or it converts a
typed ``]'' to ``)'' to match ``(``.
- Flash paren match -- If checked, typing a closing
parenthesis, square bracket, or quotation mark flashes the
matching open parenthesis/bracket/quote.
- Auto-save files -- If checked, the editor generates
autosave files (see DrScheme Files) for files that have not been saved after five
minutes.
- Map delete to backspace -- If checked, the editor
treats the Delete key like the Backspace key.
- Use platform-specific file dialogs -- If checked,
DrScheme uses the standard, platform-specific dialogs for its
find-file and save-file dialogs. Otherwise, DrScheme uses
dialogs that are the same across platforms.
- Verify exit -- If checked, DrScheme consults the user
before exiting.
- Ask before changing save format -- If checked, DrScheme
consults the user before saving a file in non-text format (see
DrScheme Files).
- Wordwrap editor buffers -- If checked, DrScheme editors
auto-wrap text lines by default. Changing this preference affects
new windows only.
- Show status line -- If checked, DrScheme shows a status
line at the bottom of each window.
- Count line and column numbers from one -- If checked, a
status line's line:column counter counts from one. Otherwise, it
counts from zero.
- Enable keybindings in menus -- If checked, some
DrScheme menu items have keybindings. Otherwise, no menu items
have key bindings. Changing this preference affects new windows
only.
- Default Fonts
This panel controls the default fonts that DrScheme uses in various
aspects of its display. Each entry corresponds to a font family, as
defined in PLT MrEd: Graphical Toolbox Manual. DrScheme uses the Modern font for
Scheme editors, and the Default font for other kinds of
editors.
- Indenting
This panel controls which keywords DrScheme recognizes for indenting,
and how each keyword is treated.
- General II
- Only warn once when executions and interactions are not synchronized -- If checked, DrScheme warns the user on the first
interaction after the definitions window, language, or liabrary is
changed without a corresponding click on Execute. Otherwise,
the warning appears on every interaction.
- Open all files as Scheme programs -- If checked,
DrScheme opens all files as Scheme programs. Otherwise, only files
that end in .ss, .scm, or .sch are recognized as
Scheme programs.
- Interactions window always active -- If checked,
every DrScheme window starts with the interactions window
visible. Otherwise, opening a file in DrScheme creates a window
where the interactions window is initially hidden. In all case,
clicking the Execute button makes the interaction window
visible.
- Check Syntax
This panel controls the font and color styles used by the Check Syntax colorizations.
