    Qt Creator is a cross-platform integrated development environment (IDE)
    tailored to the needs of Qt developers.

30
31
32
33
    Qt Creator is extensible in various ways. For example, Qt Creator
    architecture is based on a plugin loader, which means that all
    functionality beyond plugin
    loading is implemented in plugins. However, you can extend and tweak
con's avatar
con committed
34
35
36
    many parts of Qt Creator without the need to resort to coding in C++ and
    implementing such a plugin.

37
38
    This document gives you an overview of the various ways in which
    you can extend Qt Creator,
con's avatar
con committed
39
40
41
    depending on what you want to achieve, and points you to the relevant
    documentation.

    \section1 Generating Domain Specific Code and Templates

    If you regularly need to write the same code, be it little code snippets,
45
46
    whole files or classes spread over multiple files, or complete projects,
    you can create code snippets, templates, and wizards for that purpose.

    \section2 Snippets

    Typically, snippets consist of a few lines of code (although they
    can also be plain text) that you regularly
52
53
54
    want to insert into a bigger body of code, but do not want to type each
    time. For example, \c while and \c for loops, \c if-else and \c try-catch
    constructs, and class skeletons. Snippets are triggered in the same way as
Leandro Melo's avatar
Leandro Melo committed
55
56
    normal code completion (see \l{Code Assist}{Providing Code Assist}).
    Qt Creator contains a set of preconfigured snippets groups
57
58
    to which you can add your own snippets.

    You can extend the wizards in \gui {File > New File or Project} with your
    own
    file and project templates by writing XML definition files for them.

    If the above methods for code snippets and templates are not sufficient
79
80
    for your use case, you can create a custom Qt Creator plugin.
    While this gives you complete control over the wizard, it
con's avatar
con committed
81
82

84
    also requires you to write most of the UI and the logic yourself.

    If you have files with extensions or MIME types that Qt Creator does not
    handle by default, you can edit the MIME type definitions, add highlight
    definition files, and create your own text editors.

    You might find that Qt Creator could handle a particular file of yours if
    it knew about the type of its contents. For example, C++ header or source
    files with file extensions that are not known to Qt Creator. You can adapt
    the MIME type definitions in Qt Creator to your specific setup,
con's avatar
con committed
101
102
    by adding or removing file extensions and specifying magic headers.

    \section2 Text Highlighting and Indentation

111
112
113
114
115
    For text files, Qt Creator provides an easy way to add highlighting and
    indentation for file types that are not known to it by default.
    Generic highlighting is based on highlight definition files that are
    provided by the Kate Editor. You can download highlight definition files
    for use with Qt Creator and create your own definition files.

127
128
    If you need more advanced features than the MIME type and highlighting
    features described above, such as custom text completion or features that
    rely on semantic analysis, you can extend Qt Creator with a text editor of
    your own. Qt Creator provides a special API for text editors that gives you

    a basis to build on, taking away some of the pain of implementing

    \section1 Running External Tools

150
151
152
153
154
    Most software projects and development processes require various external
    tools. Several external tools, such as popular version control systems and
    build tool chains are integrated into Qt Creator. However, it is impossible
    for a single tool to cover all the use cases, and therefore you can
    integrate additional tools to Qt Creator.

156
    \section2 Simple External Tools

158
159
160
161
162
163
    In Qt Creator, you can specify tools that you can then run from a
    menu or by using a keyboard shortcut that you assign. This allows you to
    accomplish several things, with some limitations. You specify a command
    to run, arguments and input for running it, and how to handle the output.
    To specify the values, you can use a set of internal Qt Creator variables,
    such as the file name of
con's avatar
con committed
164
    the current document or project, or the currently selected text in
165
166
    a text editor. If you find variables missing, please do not hesitate
    to fill a feature suggestion.
con's avatar
con committed
167
168
    The tool descriptions are saved as XML files that you can share.

    \section2 Complex External Tools
con's avatar
con committed
175

176
177
178
    When you plan to integrate more complex tools, carefully consider whether
    there really are advantages to be gained by tightly integrating the tool
    into Qt Creator over loosely integrating it by mainly
con's avatar
con committed
179
180
181
182
    providing a means of starting the tool with fitting parameters.

    \section3 Loosely Integrating Tools

183
    If no interaction is needed between Qt Creator and the
con's avatar
con committed
184
185
186
187
    external tool, just starting an external
    application with its own user interface is preferable. That way
    cluttering the Qt Creator UI is avoided, and the tool will be
    available with a nice interface even without using Qt Creator
188
189
190
191
192
193
194
    at all.

    Usually, you can use the external tool specification files to start the
    tool. If starting the tool and handling its output require more complex
    logic, you can add a menu item to Qt Creator with a plugin.
    If you need a way to configure the tool in Qt Creator, you can add an
    \gui Options page for it.

    \section3 Interacting with Tool Output
206

207
208
209
210
211
212
    In some cases, running an external tool would not require tight
    integration with Qt Creator, but investigating the output of the tool would
    benefit from it. For example, some tools generate lists of issues in files
    that are part of the project and some tools create output that is related
    to the code. For these tools, it is useful to interactively switch between
    the output and the corresponding code.
con's avatar
con committed
213
214

    One way to handle that would be to let the tool create an output
215
216
217
218
    file, which is then opened within Qt Creator. You provide
    an editor (probably read-only) for handling this file.
    For lists of issues, consider creating task list files which are shown in
    the \gui {Build Issues} output
