Table of Contents
Inspect View shows detailed information about various elements in DVT.
Open the view from menu Window > Show View > Other... > DVT > Inspect.
To inspect an element, simply select it in a view or click on its name in the editor.
Information about the selected element will be presented in the view.
Each element shown in the Inspect View starts with an information line regarding the file and line number of the element.
The Inspect View highlights the relevant source code lines of the selected element. These lines may be surrounded with additional source code to provide a context, if necessary.
You can customize the number of lines shown by going to Window > Preferences > DVT > Maximum Inspect View context lines, or by using the key mappings detailed in the Hotkeys chapter below.
For convenience, you can see the Inspect View embedded in diagrams by clicking the Inspect Panel... button in the toolbar.
The following key mappings are available while interacting with the Inspect View.
WaveDrom is a tool that draws timing diagrams (waveforms) from a simple textual description written in JSON. DVT renders WaveDrom waveforms in the Inspect View. The waveform diagram is updated on the fly (as you type).
The waveform description can be:
When the waveform description is found in a file with a valid extension, the Inspect View will process it's content and render the diagram when opened. The waveform description file can also be embedded in comments using the @WAVEDROM_FILE pragma, followed by its location. The location of the file will be solved relatively to the current editor.
To save the diagram as an SVG file, right-click on it in the Inspect View.
DVT offers the ability to view WaveDrom diagrams through tooltips, by hovering over any waveform written inside DVT editors.
Tip: The WaveDrom documentation is available here.
Note: To specify additional file extensions, use the +dvt_wavedrom_file_ext_add+<extension> build config directive. To clear the extensions list use +dvt_wavedrom_file_ext_clear.
Note: To specify additional search file locations to use in junction with @WAVEDROM_FILE pragma, use the +dvt_wavedrom_files_location_add+<location> build config directive. To clear the extensions list use +dvt_wavedrom_files_location_clear.
Note: By default, only waveform descriptions of maximum 5000 characters are rendered. You can change this threshold from menu Window > Preferences then DVT > Editors.
Note: DVT uses WaveDrom version 2.6.8.
