<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">use QmlJS::Document::Language here instead
also, the access pattern is broken, you first have to lock the duchain, then look at m_context->...
Maybe you added more of these issues elsewhere? please double-check!</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Regarding QmlJS::Document::Language, all ExpressionVisitor has is a DUContext (from which a TopDUContext can be retrieved), but QmlJS::Document::Language is only used in ParseSession, that doesn't seem to be stored somewhere (it is instantiated on the stack in QmlJsParseJob and is never stored anywhere else).
I was looking at parsing environments (ParsingEnvironmentFile and ParsingEnvironment), but adding a new parsing environment type and a new subclass of ParsingEnvironment seems a bit complex just to avoid half a dozen byteArray() calls ("parent" is never used in big plugin.qmltypes files and only rarely used in normal QML files). Do you have any suggestion on how I can get back the language of the file?</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch adds a special-case for "parent" in ExpressionVisitor. Even if every QML object has a "parent" property of type QQuickItem, the user most of the time wants to refer to the enclosing QML component when he/she types "parent". If there is no enclosing QML component (the current component is a top-level one or something else happened), then ExpressionVisitor falls back to the old behavior and returns a QQuickItem instance.
I would like to be able to activate this special handling of "parent" only for QML files, because Javascript files may use "parent" for something else. Is it possible, given a DUContext, to find its language? (or is there a way for the QML/JS plugin to store in the DUContext that the file is a Javascript one or a QML one?)</pre>

"parent" is used to refer to the enclosing component of a sub-component, and uses are correctly built. The rest of the unit tests pass. Manual testing shows that the highlighting of "parent" and the code-completion for "parent." is as expected.</pre>
