QUICK START GUIDE

This short introduction will briefly guide you through the project setup and the user interface of Sourcetrail. The bullet point lists will tell you what to do:

Short description

Sourcetrail is an interactive source explorer that simplifies navigation in existing source code. Sourcetrail's aim is to give answers to all your questions about your source code. Sourcetrail first indexes your code and gathers data about its structure and then provides you a simple interface consisting of three interactive views, each playing a key role in getting information:

• Search:Use the search field to quickly find and select indexed symbols in your source code. The autocompletion box will instantly provide an overview of all matching results throughout your codebase.
• Graph:The graph displays the structure of your source code. It focuses on the currently selected symbol and directly shows all incoming and outgoing dependencies to other symbols.
• Code:The Code view displays all source locations of the currently selected symbol in a list of code snippets. Clicking on a different source location allows you to change the selection and dig deeper.

Sourcetrail currently supports the languages C/C++ and Java. Much of the UI design is therefore based on these languages and might change as soon as other languages are supported. For more information have a look at supported languages.

Starting up Sourcetrail

Once you installedSourcetrail successfully you are ready to run the application.

Start Window

After launching Sourcetrail you will see the Start Window. Now you can create your own project or choose a pre-indexed one.

Creating a Project

When creating a new Sourcetrail project you will use the Project Setup Wizard. This wizard splits the setup process into several subsequent steps. Depending on your project's structure and the used build system there are different types for project setup. Choosing the right setup method is important and can make the setup process a lot easier.

In the first step of the project setup you will just need to specify name and location of your Sourcetrail project.

Choosing the right project setup

Sourcetrail projects consist of multiple Source Groups. Each Source Group uses a certain language, a set of files and all configurations to index these files. There are different types of Source Groups for each supported programming language. Creating a single Source Group is sufficient for most projects.

Source Group setup for C/C++

The Source Group setup types for C & C++ are the same.

This video gives you a detailed look into project setup for C++, including best practices and strategies on how to fix errors:

Are you using CMake, Make or Qt Creator?

If you are using CMakeor Makeas build environment you can export a clang JSON Compilaton Databaseas compile_commands.jsonfile. A Compilation Database holds all information necessary for building the project, such as source files, include paths and compiler flags. Having a Compilation Database makes project setup within Sourcetrail a lot easier. We recommend using this approach if possible.

Exporting a Compilation Database:

• From CMakeby defining the CMAKE_EXPORT_COMPILE_COMMANDSflag. (not supported on for Visual Studio CMake generators)
• For Makeprojects use Bear. Bear generates a compile_commands.jsonfile during a simulated build process. Bear has been tested on FreeBSD, GNU/Linux and OS X.
• From Qt Creator since version 4.8by selecting the "Generate Compilation Database" from the "Build" menu.

If you managed to export a compile_commands.jsonfile, then please continue at Create a Source Group from Compilation Databaseand come back after you finished creating the project.

Are you using Visual Studio?

If you are using Visual Studio you can continue at Source Group creation from Visual Studioand export a Compilation Database with our Visual Studio Plugin.

Create empty

If none of the above options apply to your project, please continue at Create an empty C/C++ Source Groupand come back here as soon as the project is created.

Source Group setup for Java

Are you using Gradle?

If you are using Gradle you can continue at Source Group creation from Gradleto automatically setup your Source Group using your Gradle build configuration.

Are you using Maven?

If you are using Maven please continue at Source Group creation from Mavento automatically setup your Source Group using your Maven build configuration.

Create empty

If you do not have your project configured using Gradle or Maven, please continue at Create an Empty Java Source Groupand come back here as soon as the project is created.

Source Group setup for Python

Create empty

If you want to browse your Python source code with Sourcetrail, please continue at Create an Empty Python Source Groupand come back here as soon as the project is created.

Source Indexing

After the project is created, Sourcetrail will ask you whether you want to start indexing. Click Startand wait for the indexing to finish, which might take a little while. The Indexing Dialogand the Status Barwill give you information about the progress. Otherwise the UI will be empty. Sourcetrail indexes all named symbols and their relationships throughout the provided source files.

After indexing has finished, Sourcetrail will show an overview of all indexed symbols in the graph viewand some statistics in the code view.

If the indexing yields errors, the status view will be shown with a list of errors. You can click on the errors label on the right side of the status bar or on one of the errors in the table to see their location.

UI Intro

As already mentioned Sourcetrail's user interface is split into three main views. Their arrangement can be changed however you wish, you can even detach them from the main window and put them on different screens (see Window Widgets).

The three views show information about the currently selected symbol. The search field provides the name, the graph visualization shows its relationships to other symbols and the code view displays all locations the symbol gets referenced throughout the codebase.

Search Field

The search fieldallows for easy access to all indexed symbols. Use it to find all the classes and functions you wish to investigate. Apart from that is also holds the UI buttons for navigating back & forwardas well as refreshing.

When entering a search query the autocompletion popupwill provide you with a concise list of all matching symbols. Note that Sourcetrail uses a fuzzy matching algorithm, that allows you to skip characters while entering a query.

Graph Visualization

The graph visualizationdisplays the currently selected symbol in an active state and all other symbols it shares relationships with. The visualization is made up of nodes and edges.

• Nodes:All named symbols in your source code will be displayed as different nodes, such as functions, classesor files. Nodes with members (like classes) can be expanded to show all their contents, the number at the expansion arrow shows how many members are hidden. Clicking a node will activate it and update all the views to the new selection. Dragging a node can be used to change its position.
• Edges:The relationships between the symbols are displayed as different edges, such as type use, function callor file include. Sometimes edges get bundled together and are displayed as an aggregationedge that shows a number of how many edges it contains. Clicking an edge will highlight its source location in the code view.

Colors:

The different node and edge types are also displayed using different colors. The default color scheme uses this convention:

Color	Node	Edge
gray	types and classes	type use
yellow	functions and methods	calls
blue	variables and fields	variable access

Hatching:

Nodes displayed with a striped hatching, are nodes that were used within your indexed source files, but were not defined. Clicking them shows all locations where they are used, without providing their declaration.

Legend:

For a full list on all existing nodes and edges take a look at the integrated Graph Legendby clicking the ?-button in the bottom right corner of the Graph View.

Code View

The code viewdisplays all locations of the currently active symbol within the indexed source files. It does not allow for editing the source code. Syntax highlighting is used to increase readability. Source locations that are surrounded by a box when hovered can be clicked to activate the respective symbol. Active source locations are highlighted.

The source locations are displayed as code snippets, containing the line of interest and extra lines added to the top and bottom to give information about its context. Code snippets are then bundled together into files.

Note:A file can be selected as active symbol by clicking its name in the title bar. By clicking the title bar or the icon on the right hand side of the title bar, the file can switch between 3 different states:

• Minimized:The file does not show any content
  
• Snippets:The file displays the snippets containing active locations separated by lines.
  
• Maximized:The code viewswitches to single file modeand the whole content of the file is visible.
  

For more information please have a look at Code View Files.

Start exploring!

After reading this quick guide, you know the basics of Sourcetrail's user interface and you are able to start exploring your codebase. Sourcetrail will allow you to see your source code from a whole new perspective, by giving you a concise overview of its parts and a faster way of drilling down to its internals, while always maintaining the connection to the implementation details of the actual source code.

For more detailed information please have a look at the much more extensive instruction manual below.

If you have feedback for us, please don't hesitate and let us know by writing to [email protected], we'd be glad to hear from you.

The Sourcetrail team wishes you a good start with our product, lots of saved time, increased productivity and much cleaner code.

FAQ

INSTALLATION

On Windows

Download and open the zip file and extract its contents into a temporary folder of your choice. Run the setup.exeand go through the wizard. You can now launch Sourcetrail from your start menu.

On Mac

Download and open the Sourcetrail.dmg file and drag Sourcetrail.app into the applications folder. You can now launch Sourcetrail from your Applications.

On Linux

Download Sourcetrail.tar.gz file and extract it. To start Sourcetrail run the Sourcetrail.shscript. Sourcetrail creates a folder ~/.config/sourcetrailat the first run, this is the folder for Sourcetrail settings.

To Install Sourcetrail run the install.shscript with sudo, it will install Sourcetrail to /opt/sourcetrailand create /usr/bin/sourcetrailsymlink.

Data folder

The data folder holds certain files that are used by Sourcetrail to run the program. After following the installation instructionsthe data folder should be located in the following locations on your platform.

Platform	Location
Windows	C:/Users/You/AppData/Local/Coati Software/Sourcetrail (used for dynamic data and settings) install_directory/Coati Software/Sourcetrail/data (used for static app data)
Mac	~/Library/Application Support/Sourcetrail
Linux	~/.config/sourcetrail

Finding System Header Locations

On Windows

These files usually ship with your compiler. For the Visual Studio IDE the system headers can be found at:

<path_to_visual_studio>/VC/include/

If you don't use the Visual Studio IDE you can also try to find your system headers in a subdirectory of:

C:/Program Files (x86)/Windows Kits/

On Mac

Run this command in your terminal:

gcc -x c++ -v -E /dev/null

You will find the header search paths your compiler uses in the output between these two lines:

#include <...> search starts here:      
.      
.      
.      
End of search list.

On Linux

gcc -x c++ -v -E /dev/null

or

clang -x c++ -v -E /dev/null

You will find the header search paths your compiler uses in the output between these two lines:

#include <...> search starts here:      
.      
.      
.      
End of search list.

Finding Java Runtime Library Location

The current version of Sourcetrail requires an installation of the Java 8 runtime environment to index any Java project. Make sure that Sourcetrail and your JRE share the same kind or architecture (a 32 bit Sourcetrail requires a 32 bit JRE). To locate the required library file, please refer to the applicable description below.

On Windows

The Java Runtime Library (called jvm.dll) can be found inside of your JRE install folder and looks like this:

<path_to_jre>/bin/client/jvm.dll

On Mac

The Java Runtime Library (called libjli.dylib) can be found inside of your JRE install folder. Run the following command in your terminal to find the location of your default Java installation:

/usr/libexec/java_home

This should give you a path looking like this:

/Library/Java/JavaVirtualMachines/<jdk_version>/Contents/Home

The "libjli.dylib"should be available at:

/Library/Java/JavaVirtualMachines/<jdk_version>/Contents/Home/jre/lib/jli/libjvm.dylib

Insert the full path to libjli.dylibinto the Java Pathsetting in the Preferences Window.

On Linux

The Java Runtime Library (called libjvm.so) can be found inside of your JRE install folder and looks like this:

<path_to_jre>/lib/<arch>/server/libjvm.so

Tab Width	Define the space width of tabs in the code view.
Text Encoding	Define the Text Encoding used for displaying your source code.
Color scheme	Choose which color scheme Sourcetrail should display. The color schemes are located in data/color_schemes/
Animations	Define if animations are used within the user interface.
Built-In Types	Define whether built-in types such as int or bool are shown when referenced in the graph view.
Directory in File Title	Enable display of the parent directory of a code file relative to the project file.
Auto Scaling to DPI	(Linux only)Define if automatic scaling to screen DPI resolution is active. This setting manipulates the environment flag QT_AUTO_SCREEN_SCALE_FACTOR of the Qt framework. Choose 'system' to stick to the setting of your current environment.
Scale Factor	(Linux only)Define a screen scale factor for the user interface of the application. This setting manipulates the environment flag QT_SCALE_FACTOR of the Qt framework. Choose 'system' to stick to the setting of your current environment.
Scroll Speed	Define a multiplyer for the default scroll speed. Values smaller than 1 slow down scrolling while values greater than 1 increase the scroll speed.
Graph Zoom	Switch the default mouse wheel behavior in the graph between scrolling and zooming.
Logging	Ticking this box enables logging to console and to a log file. This option is disabled by default to speed up Sourcetrail. If you encounter problems while running Sourcetrail, we recommend to enable this option so you have somewhere to start looking for a cause.
Indexer Logging	When enabled Sourcetrail will log detailed information during indexing. This log data can help us fix issues.
Automatic Update Check	Check to automatically check whether a new version of Sourcetrail is available once every day.
Sourcetrail Port	Port number that Sourcetrail uses to listen for incoming messages from plugins.
Plugin Port	Port number that Sourcetrail sends outgoing messages to.
Indexer threads	Define how many parallel threads are used during indexing. Setting this value to defaultwill cause Sourcetrail to detect the ideal number of threads based on the CPU and use as many threads for indexing.
Multi process C/C++ indexing	Enable C/C++ indexer threads to run in a different process. This prevents the application from crashing due to unforseen exceptions while indexing.
Java Path	If you want to use Sourcetrail on Java source code, please specify a path to your Java 8 runtime library. Please keep in mind that a 32 bit Sourcetrail requires a 32 bit version of Java while a 64 bit Sourcetrail requires a 64 bit Java to be working correctly. You can either use the button below for automatic detection or add the path manually. For instructions on how to find your Java runtime path see Finding Java Runtime Library Location.
JRE System Library	Add the jar files of your JRE System Library. These jars can be found inside your JRE install directory. You can either use the button below for automatic detection or add the paths manually.
Maven Path	Only required for indexing projects using Maven. Provide the location of your installed Maven executable. You can also use the auto detection.
Post Processing	Enable a post processing step to solve unsolved references after the indexing is done. These references will be marked "ambiguous" to indicate that some of these edges may never be encountered during runtime of the indexed code because the post processing only relies on symbol names and types.
Global Include Paths	Set header search paths that are used for allof your projects (e.g. std headers). An option for automatic detection of these paths is available for Clang, GCC and the Visual Studio compiler. For instructions on how to add paths manually see Path List Box. For instructions on how to find the system header paths see Finding System Header Locations.
Global Framework Search Paths	(macOS only)Define the search paths for .frameworkfiles for all of your projects. An option for automatic detection of these paths is available for Clang and GCC. For instructions on how to add paths see Path List Box.

Project Setup Wizard

The Project Setup Wizard lets you create a new Sourcetrail project. It allows for defining name and location of your project Sourcetrail and adding several Source Groups, that define which source files will be indexed. There are several ways to create Source Groups. It is sufficient to add only one Source Group for most projects.

For detailed information continue at PROJECT SETUP.

Indexing Dialogs

These dialogs will be used while Sourcetrail indexes your project. The whole user interface will be frozen as long as these dialogs are visible.

Start Indexing Dialog

This dialog displays the number of files for indexing and clearing before indexing starts. There are different refresh modes:

• Updated files:Reindexes all files that were modified since the last indexing, all files depending on those and new files.
• Incomplete & updated files:Reindexes all files that had errors during last indexing, all files depending on those and all updated files.
• All files:Deletes the previous index and reindexes all files.

Shallow Python Indexing
For Python projects a checkbox Shallow Python Indexingis additionally displayed. When checked, references within your code base (calls, usages, etc.) are resolved by name, which is imprecise but much faster than in-depth indexing. Use this option for a quick first indexing pass and start browsing the code base while running a second pass for in-depth indexing.

Interactions:

• Swith indexing mode by clicking a different option.
• Clicking Cancelwill abort indexing.
• Clicking Startwill start the file clearing and indexing.

Progress Dialog

This dialog shows that Sourcetrail is currently doing processing that can't be interrupted.

Interactions:

• Clicking Hidewill hide the dialog. You can display it again by clicking on the indexing progress bar in the status baror refreshing.

Indexing Dialog

This dialog shows the indexing progress of your project, by displaying the number of already indexed files, the last file that was started indexing, the number of errors and a progress estimate in percent.

Interactions:

• Clicking Stopor pressing ESC will interrupt indexing. Sourcetrail will still wait for the already running indexer threads to finish. You can continue indexing later by refreshing.
• Clicking Hidewill hide the dialog. You can display it again by clicking on the indexing progress bar in the status baror refreshing.

Finished Indexing Dialog

This dialog is shown after indexing finished, giving you information about indexed files, duration and errors.

Interrupted Indexing Dialog

This dialog is shown after indexing was stopped, giving you information about indexed files, duration and errors. You can choose to either use the new index or continue using the old one.

Interactions:

• Clicking Discardwill discard the new index.
• Clicking Keepwill switch your project to the new index and discard the old one.

Files & Directories to Index	These paths define the files and directories that will be indexed by Sourcetrail. Provide a directory to recursively add all contained source and header files. If your project's source code resides in one location, but generated source files are kept at a different location, you will also need to add that directory. You can make use of environment variables with ${ENV_VAR}. For instructions on how to add paths see Path List Box.
Excluded Files & Directories	These paths define the files and directories that will be left out from indexing. Hints: You can use the wildcard *which represents characters except \or /(e.g. src/*/test.hmatches src/app/test.hbut does not match src/app/widget/test.hor src/test.h) You can use the wildcard **which represents arbitrary characters (e.g. src**test.hmatches src/app/test.has well as src/app/widget/test.hor src/test.h) You can make use of environment variables with ${ENV_VAR} For instructions on how to add paths see Path List Box.
Source File Extensions	Define the valid extensions for source files including the dot e.g. .cpp. Sourcetrail will only try to index files that match one of these extensions.

Interactions:

If your project requires additional includes to compile (e.g. Boost for C++, etc.), please specify their location here.

Additionally you can also specify Global Include Paths, which will be used by all your projects. These are usually the paths to system headers, which can also be auto detected by choosing a compiler below and pressing detect.

Setting	Description
Include Paths	Include Paths are used for resolving #include directives in the indexed source and header files. These paths are usually passed to the compiler with the '-I' or '-iquote' flags. Add all paths #include directives throughout your project are relative to. If all #include directives are specified relative to the project's root directory, please add that root directory here. If your project also includes files from external libraries (e.g. boost), please add these directories as well (e.g. add 'path/to/boost_home/include'). You can make use of environment variables with ${ENV_VAR}. For instructions on how to add paths see Path List Box.
Global Include Paths	The Global Include Paths will be used in all your projects in addition to the project specific Include Paths. These paths are usually passed to the compiler with the '-isystem' flag. Use them to add system header paths (See Finding System Header Locationsor use the auto detection below). For instructions on how to add paths see Path List Box.

Interactions:

• Clicking auto-detectopens a dialog where you can add directories that will be automatically searched for possible header files matching the include directives in your source files. The detection will add the detected Include Paths to the list.

Sourcetrail will index your project based on the compile commands this file contains using all include paths and compiler flags of these compile commands. The project will stay up to date with changes in the compilation database on every refresh. You can make use of environment variables with ${ENV_VAR}.
Header Files & Directories to Index	Your Compilation Database already specifies which source files are part of your project. But Sourcetrail still needs to know which header files to index as part of your project and which to skip. Choosing to skip indexing your system headers or external frameworks will significantly improve the overall indexing performance. Use this list to define which header files should be indexed by Sourcetrail. Provide a directory to recursively add all contained files. You can make use of environment variables with ${ENV_VAR}. Hint: Just enter the root path of your project if you want Sourcetrail to index all contained headers it encounters. For instructions on how to add paths see Path List Box.
Excluded Files & Directories	These paths define the files and directories that will be left out from indexing. Hints: You can use the wildcard *which represents characters except \or /(e.g. src/*/test.hmatches src/app/test.hbut does not match src/app/widget/test.hor src/test.h) You can use the wildcard **which represents arbitrary characters (e.g. src**test.hmatches src/app/test.has well as src/app/widget/test.hor src/test.h) You can make use of environment variables with ${ENV_VAR} For instructions on how to add paths see Path List Box.

Custom Command

Define a command line call that will be executed for each source file in the Source Group. You can pass different pre-defined parameters:

• %{SOURCE_FILE_PATH}: The path to each source file in the source group (mandatory)
• %{DATABASE_FILE_PATH}: The path to the database of the project
• %{DATABASE_VERSION}: The database version of the used Sourcetrail instance
• %{PROJECT_FILE_PATH}: The path to the project file

Setting	Description
Custom Command	The command line call executed for each source file.
Run in Parallel	Whether files should be processed in parallel.
Files & Directories to Index	These paths define the files and directories that will be indexed by Sourcetrail. Provide a directory to recursively add all contained source and header files. If your project's source code resides in one location, but generated source files are kept at a different location, you will also need to add that directory. You can make use of environment variables with ${ENV_VAR}. For instructions on how to add paths see Path List Box.
Excluded Files & Directories	These paths define the files and directories that will be left out from indexing. Hints: You can use the wildcard *which represents characters except \or /(e.g. src/*/test.extmatches src/app/test.extbut does not match src/app/widget/test.extor src/test.ext) You can use the wildcard **which represents arbitrary characters (e.g. src**test.extmatches src/app/test.extas well as src/app/widget/test.extor src/test.ext) You can make use of environment variables with ${ENV_VAR} For instructions on how to add paths see Path List Box.

Create a Clang Compilation Database from a VS Solution

As a Clang based tool Sourcetrail supports the JSON Compilation Database format for simplified project setup. This extension enables you to generate a JSON Compilation Database from your Visual Studio projects and solutions. The great news is: This format is independent from the Sourcetrail tool, so you can also use the generated Compilation Database to run other Clang based tools.

The wizard for creating a Compilation Database is located in the Sourcetrail section in the VS menu bar. Note that the option is only useable if a solution containing at least one C/C++ project is loaded.



In the Compilation Database wizard you can select projects you want to include in the JSON file as well as the desired build target platform and configuration and a number of other options.



Option	Description
Select Projects	The list of C/C++ projects in your solution. Check all projects you want to be included in the generated JSON Compilaton Database file.
De/Select All	Will select all projects if at least one project is not selected. If all projects are selected they will all be unselected.
Configuration	A dropdown list of the available build configurations. The selected configuration affects include paths and compile flags for the Compilaton Database.
Platform	A dropdown list of the available target platforms. The selected platform affects include paths and compile flags for the Compilaton Database.
Browse	Opens a folder browser to select the directory where the Compilaton Database will be created in. By default it is the directory of your solution. Instead of using the folder browser you can also paste a path into the adjacent text field.
filename	This is the name for the Compilaton Database file. By default it is the same name as your solution.
C Standard	A dropdown list of all C standards supported by Sourcetrail. If your projects contain C files select the appropriate standard.
Cancel	Aborts the process and closes the wizard.
Create	Creates the Compilaton Database using the specified options. Note that at least one project has to be selected to start creating.

Once the Compilaton Database was successfully created it can be found in the specified target directory. From this Compilaton Database you can create a Sourcetrail project as described above.

Settings

Network settings and logging options can be changed in the plugin's Tools/Options entry.




Option	Description
File Logging	Enable log output for the plugin. Additionaly to the output file, log messages will also be displayed in VS'
Log Obfuscation	Obfuscate project names and file names as well as directories in the log output. Note that already logged data will not be obfuscated retroactively. A dictionary, mapping obfuscated names to original names, will be created in a seperate file.
Sourcetrail Port	The port on which Sourcetrail will receive messages. Note that this must match the port setting in Sourcetrail itself.
Thread Count	The number of threads used during creation of the Compilation Database
VS Port	The port on which Visual Studio will receive messages. Note that this must match the port setting in Sourcetrail itself.

Logging

The plugin offers optional file logging. Should you ever have issues with the plugin we recommend to turn logging on. This will help to pinpoint and resolve the root cause faster.

Logs will be created in ..\AppData\Local\Coati Software\Plugins\VSfolder. A new log file will be created every time you restart VS and logging is enabled.



Note that the logs will include project names and file names as well as directories specific to your project. If you wish to keep this informatin secret you can enable log obfuscation.

Project- and file names as well as directories will be replaced by an alphanumeric sequence. The sequence has the form a0, b0, c0,..., a1, b1, c1,.... Note that after switching on obfuscation, already logged data will not be obfuscated retroactively. No log files will be send to Coati Software automatically. You can check any file you may want to send us for sensible information before sending it.

A dictionary, mapping obfuscated names to original names, will be created in your log folder if log obfuscation is switched on. When during the support process we refer to project items by their obfuscated name you can still make sense of it. Do not send the dictionary to anybody else.

Lastly, log messages are also displayed in the VS output window. This is tied to file logging and is not enabled or disabled separately.



IDE Communication Protocol

Sourcetrail's IDE plugins communicate with Sourcetrail via sockets, using TCP. Sourcetrail implements a number of messages to provide an interface for the plugins.

This chapter explains the general structure of those messages, followed by a list of possible message types.

Message Structure

The basic structure of the messages used by Sourcetrail plugins consists of a prefix to identify the message type, followed by no, one, or multiple parameters and ends with an 'end-of-message' token. Parameters and tokens are seperated by a 'divider' token.

Name	Token	Description
messageType	see below	A string that determines how the message will be interpreted by Sourcetrail or the plugin
divider	>>	Seperates the tokens of the message
parameter	see below	Typically an integer or string
endOfMessage	<EOM>	Helps to determine the end of a message

Messages have the following form:

messageType<<parameter<<...<<parameter<EOM>

Message Types

Sourcetrail does implement a number of message types that can be used by Sourcetrail plugins. In the following is a list of the messages that Sourcetrail may send to plugins and messages that may be sent by a plugin to Sourcetrail.

Note that you can chose which messages you want to implement. Sourcetrail will not make problems if you chose to ignore certain messages.

Incoming messages

These messages may be received by a plugin.

Message	Parameters	Description
moveCursor	fileLocation: string row: integer column: integer	Set the cursor of your editor or IDE to the given file location. Note that fileLocation is the absolute path and name of the target file.
createCDB		Sourcetrail may send this message to prompt your plugin to create a Compilation Database (CDB). Once the CDB is ready you may want to respond with a createCDBProjectmessage.
ping		Sourcetrail may send a ping to determine if anybody is listening. Respond with a ping message yourself. Sourcetrail will not respond to this message.

Outgoing messages

Your plugin may send these messages to Sourcetrail.

Message	Parameters	Description
setActiveToken	fileLocation: string row: integer column: integer	Tells Sourcetrail to shift focus to the token located at the given position. Note that fileLocation is the absolute path and name of the target file.
createCDBProject	cdbPath: string headerPaths: string	If your plugin can provide a Compilation Database this message can prompt Sourcetrail to import it and display an appropriate dialog for the user. headerPaths is a list of the base project's header include paths. Seperate the single paths using the divider token. You can add as many paths as you need.
ping		Your plugin may send this message to Sourcetrail to tell it it's listening.
