The Files and lines view displays coverage data for files and their lines.
Read on, or click a part of the image below to jump straight to the help for that area.
The Files and Lines view is structured as a hierarchy of filenames and the hooked lines within those files.
As with many of the tab views, the display is split into two resizable panes.
•the left side lists a summary of the file and line coverage data
•the right side shows source code for any file or line selected on the left
We'll cover the file and line list and its popup menu first, and then the source code view.
The file and line list
Each line in the view displays the following:
•the filename or function line within the file
•for files, the percentage of hookable lines that have been visited, while line data echos the 'progress bar' of their file
•for files, the number of hooked lines in the file, (unhooked lines in brackets)
This is not the same as the total number of lines in a file, which may include comments, declarations and white space.
Neither is it the same as the number of hookable lines since some lines or functions can be excluded from hooking.
The count also includes lines which should have been hooked but failed, for example because the instrumentation level was set low. The unhooked line count is shown in brackets.
•for files, the number of different lines that have been visited
•the total visit count for the file or line
This may be equal to the number of different lines visited unless you're counting each visit separately:
Line colours
Each line in the list is colour coded to indicate one of the following:
•the file or line has not been visited at all
•the file has been visited to some extent (or the line has been visited)
•every hookable line in the file has been visited, i.e. 100% file coverage
•the line in the file could be hooked
Unhooked lines
Depending on what file or DLLs hook filters are set up, not all the hookable lines in a header file may attempt to be hooked.
Only those that are actually used (e.g. via macros or inlines) in the program may actually be hooked.
By default, lines that could not be hooked don't stop the coverage from reaching 100%, but you can change this.
In this example below, the instrumentation level was set low ('incomplete but faster') to force significant numbers of unhooked lines.
Scrollbar visualisations
To the right of each pane, beside the vertical scrollbars, you'll see a coloured area which represents the coverage.
For the file and line list, the visualisation shows the coverage of each item in the list - reflecting the progress meters in the second column.
For the source code view, the visualisation shows the coverage of each line in the file
These visualisations provide a snapshot view of the whole list of files or the whole source file.
Irrespective of how much you can see in the file and line list or in the source code view, you can still get a global overview of the coverage distribution.
Files and lines options
The coverage controls are shown below.
Window orientation
The horizontal or vertical orientation of the statistics and source code panes can be toggled with the orientation button.
Updating the display
•Refresh 
updates the display - as does the 
button on the Tools menu and toolbar
Display settings
•Highlight unvisited lines highlights rows for any lines that have not been visited (on by default)
If switched off, unvisited lines appear white - or whatever colour you've set as the unselected colour.
•Show Path for filenames, shows the short file name or the longer file path in the File column of the data
•Show unhooked functions display information about lines that could not be hooked (off by default)
This means unhookable lines, for example, lines that were too short, rather than lines or functions that are deliberately set not to be hooked.
Files and lines menu options
The following popup menu is available over the data area to add filters, edit code, or expand and collapse the view.
Menu options: Instrumentation Filter
The instrumentation filter lets you add filters at different levels of granularity:
•Exclude Filename adds a new filter to the Source Files Filter settings, excluding it from the results of subsequent sessions
•Exclude Directory excludes all files in the same directory as the selected file
From the sub menu, choose the directory level at which you want to exclude files, right up to the drive specifier if you need to
•Exclude DLL excludes all files belonging to the same executable or DLL as the selected file
This adds a filter to the Hooked DLLs settings.
The other options all add a filter to the Class and function filter settings
•Filter By Class excludes all functions in the selected class
Example filter: CTeststakDoc::
•Filter By Class And Method excludes only the selected class functions
Example filter: CTeststakDoc::OnNewDocument
•Filter By Method excludes all functions in the selected class
Example filter: OnNewDocument
Filters become effective at the start of the next session. Adding a filter during a session will show the relevant rows in grey so that you can see which items would be filtered, but the coverage results will continue to be included for the rest of the current session.
Menu option: editing source code
•Edit Source Code... opens the default or preferred editor to edit the source code
Menu options: collapse / expand trace
•Expand or Collapse Entry shows and hides the selected section in the view, the same as using the 
or 
buttons
•Collapse All completely collapses all sections
•Expand All expands all the sections
The file source code view
Clicking on a file in the file and line view shows that file in the source code view on the right, with the selected line highlighted.
The source code uses syntax highlighting by default, with the background colour of the line indicating if the line has been visited, is unvisited or could not be hooked.
Icons are displayed next to hooked and unhooked lines indicating visit and hook status and visit counts are shown in-line with the code.
Hovering over a line for a short period of time shows a tooltip with the number of visits to the line.
Contiguous groups of lines can be collapsed and hidden from view.
Source code file information
On the right hand panel, above the source code, you'll find some information about the source file
The details shown include the following:
•'quick view' details for visited and unvisited lines, pink for unvisited, light green for partial visited, and dark green for 100% visited
•the source code filename and the executable or DLL to which it belongs
•the same statistics as seen for the file in the left hand panel
Browsing visited and unvisited lines
When a line has been selected in the files and lines view, the line is marked in the source code.
You can then use the following buttons to move to adjacent lines;
•
show the previous and next unvisited line of code in the file
and 
+ also navigate forwards and backwards when the source code has focus.
•
show previous and next visited line of code in the file
The arrows are grey when disabled, for example when a filename rather than a line is selected on the left.
and + also navigate forwards and backwards through the visited lines.
•Line step by individual lines of code
•Group step by groups of contiguous visited or unvisited lines
Keyboard access: Find and Goto
When the data view or the source code view has focus, some keyboard access is available to search for filenames, code or to navigate to numbered lines.
Find text in data view
In the data view, 
+ 
displays a dialog that will allow you to search by full or partial match for text in the filenames in the first column.
Find text in source view
In the source code view + lets you search by full or partial match anywhere in the file
Goto line
In the source code view, + 
displays a goto-line dialog
.
