[Tool Window] Include Graph

Tools in Detail

Include Formatter

Select a group of includes, right click, select "Format Selected Includes"

The behavior of this command is controlled by various options which can be configured in Tools>Options>Include Toolbox>Include Formatter:

  • Formatting
    • Delimiter Mode
      Optionally change "" to <> or vice versa
    • Slash Mode
      Optionally changes / to \ or vice versa
    • Remove Empty Lines
      Optionally removes empty lines within the selection
  • Path Reformatting
    • Ignore File Relative
      If true, the local file path will not be considered for reformatting the path
    • Mode
      Configures the strategy that should be used to determine new include paths
  • Sorting
    The tool will always sort all selected includes alphabeticaly, unless..
    • Precedence Regex
      Every line gives a regex - if an include matches a regex, it has precedence over all other includes that do not match any, or a later regex. Multiple includes that match the same regex are still alphabetically sorted.
    • Sort by Include Type
      Optionally puts all inclues with either quotes or angle brackets first.

All operations are performed in the order in which they occur on the option page.

Trial and Error Include Removal

The name says it all: This tool will try to remove an include, recompile, see if it works and proceed to the next one accordingly.
The tool can be started an all compilable files in a VC++ by right clicking on the code window. There is also a special version in the Project context menu which will run over every single file in the project (takes very long).

Obviously the results of this tool are far from optimal and the process can take a while.

The exact behavior of this command can be controlled in Tools>Options>Include Toolbox>Trial and Error Include Removal:

  • Ignore List
    A list of regexes. If the content of an include matches any of these, it will never be removed.
  • Ignore First Include
    If true the top most include will always be ignored
  • Removal Order
    Wheater the tool should run from top to bottom or bottom to top (this can make a difference on the end result)

To suppress removal of a single include, add a comment to its line containin_g_ $include-toolbox-preserve$

Include-What-You-Use Integration

Include Toolbox with an integration of the free Include-What-You-Use. By default (see Tools>Options>Include Toolbox>Include-What-You-Use) it is downloaded together with a VC++ specific mapping file from this github repository upon first use (and whenever there is a newer version available in this repository).

Again, it can be activated by right clicking on a C++ Code file in a VC++ document. The Option page exposes most of IWYU's command line options and provides the option to directly apply the results. The complete output will be displayed in the Include Toolbox output window.

IWYU often does not work as expected - for more information look at the official docs.

To suppress removal of a single include, add a comment to its line containin_g_ $include-toolbox-preserve$

Include Graph

The Include Graph tool window shows you all (transitive) includes of a file either in a hierarchical view or grouped by folder. You can find it the View menu under View>Other Windows>Include Graph.

There are two modes of parsing to choose from:

  • Direct Parsing (default)
    • Uses a simplistic handwritten parser!

      • Works on all files!

      • Does not further parse any file that is in one of the folder listed in Tools>Options>Include Toolbox>Include Graph>Graph Endpoint Directories

        • (To prevent meaningless drilling down in standard library files)
    • Completely Ignores #pragma once and preprocessor!
      • If an
    • Has information on exact line number an include was done and double click in the hierarchy jumps to the place
  • Compile /showIncludes
    • Compiles the file with vc.exe /showIncludes and parses the output
      • Works only on compilable files
    • Output depends on preprocessed file - sticks to currently active preprocessors and pragmas
    • No information about #include line numbers, double click jumps to the including file

The "Grouped by Folder" view shows only unique included files in a minimal folder tree. This can be useful to get a feeling of the modules a file is dependent on.

FAQ:

  • Why don't you apply the formatting to all includes within a file?
    This may sound desirable, but is very messy if there are optional includes (preprocessor) or specific exceptions where not all includes should be in the same place or in the default order.
  • XY didn't work, what is going on?
    Look in the output window for Include Toolbox to get more information.
