I’ve been really, really lazy with adding code completion via DTDs and/or schemas for XML in RSTALanguageSupport, so in the meantime I decoded to add a simpler element/attribute completion scheme.
If you grab the latest from Git, RSTALanguageSupport’s XML support will now offer code completion suggestions for XML element and attribute names:
XML Element Completion
How does it decide what to suggest?
For element names, it scans the editor’s contents for any other elements that start with the prefix you’ve typed so far. For attributes, it scans for other places where you’ve completed an element of the type you’re adding an attribute for; it then suggests any attributes you’ve used for that element elsewhere in the file (and haven’t currently used in the current element):
XML Attribute Completion
This kind of completion support is pretty handy when you’re editing a larger document, and know you’ve done “the right thing” elsewhere in the file, but cannot recall what it is offhand. Just let RSTA tell you what to type.
