The preferences dialog comprises several panels:
- Font
This panel controls the main font used by DrScheme.
- Indenting
This panel controls which keywords DrScheme recognizes for indenting,
and how each keyword is treated.
- 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.
- 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).
- Wrap words in 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, the status line's line:column counter counts from
one. Otherwise, it counts from zero.
- Display line numbers in buffer; not character offsets -- If checked, the status line shows a line:column
display for the current selection rather than the character offset
into the text.
- 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.
- Automatically print to postscript file -- If checked,
printing will automatically save postscript files. If not, printing
will use the standard printing mechanisms for your computer.
- Use separate dialog for searching -- If checked,
then selecting the Find menu item opens a separate
dialog for searching and replacing. Otherwise, selecting
Find opens an interactive search-and-replace panel at
the bottom of a DrScheme window.
- 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 teachpack is
changed without a corresponding click on Execute. Otherwise,
the warning appears on every interaction.
- Enable backtrace bug icon in teaching languages -- If
checked, the teaching languages will display a clickable bug icon when
there is stack information to display, along with the error message.
- Check Syntax
This panel controls the font and color styles used by the Check Syntax colorizations.
