# Hinterland¶

Enable code autocompletion menu for every keypress in a code cell, instead of only calling it with tab.

The nbextension adds an item to the help menu to turn auto-hinting on and off, and offers some options for configuration:

## Options¶

• hinterland.hint_delay: delay in milliseconds between keypress & hint request. This is used to help ensure that the character from the keypress is added to the CodeMirror editor before the hint request checks the character preceding the cursor against the regexes below.
• hinterland.enable_at_start: Whether to enable hinterland’s continuous hinting when notebook is first opened, or if false, only when selected from the help-menu item.
• hinterland.hint_inside_comments: Whether to request hints while typing code comments. Defaults to false.
• hinterland.exclude_regexp: A regular expression tested against the character before the cursor, which, if a match occurs, prevents autocompletion from being triggered. This is useful, for example, to prevent triggering autocomplete on a colon, which is included by the default Completer.reinvoke pattern. If blank, no test is performed. Note that the regex will be created without any flags, making it case sensitive.
• hinterland.include_regexp: A regular expression tested against the character before the cursor, which must match in order for autocompletion to be triggered. If left blank, the value of the notebook’s Completer.reinvoke_re parameter is used, which can be modified by kernels, but defaults to /[%0-9a-z._/\\:~-]/i. Note that although the Completer.reinvoke_re default is case insensitive by virtue of its /i flag, any regex specified by the user will be created without any flags, making it case sensitive.
• hinterland.tooltip_regexp: A regular expression tested against the character before the cursor, which if it matches, causes a tooltip to be triggered, instead of regular autocompletion. For python, this is useful for example for function calls, so the default regex matches opening parentheses. Note that the regex will be created without any flags, making it case sensitive.
