YAML Text View

Home Prev Top Next

Text View provides a number of YAML editing features, from pretty-printing to document validation while editing. These features are described below.


Note:YAML document structure in Text View is denoted with indentation, which should be set with spaces, not tabs.


Pretty-printing, font colors, and display

Pretty-printing formats the YAML document with hierarchical indentation (see screenshot below). You can define pretty-printing options in the Options dialog (Tools | Options | Pretty-printing). The document text is marked in different colors according to their syntax. Font colors are set in the Fonts and Colors section of the Options dialog (Tools | Options | Fonts and Colors).


Other useful features of the YAML Text View are (i) line numbers in the line number margin and (ii) text-folding nodes in the folding margin. The text-folding nodes can be collapsed/expanded to better navigate and view the document. Both margins (line numbers and text folding) can be set to be shown or hidden in the Text View Settings dialog (View | Text View Settings); this dialog can also be accessed via the pretty printing options.


Node locator expressions in YAML documents

To get the XPath/XQuery location expression of a node in the YAML document, click inside the node and then select the command Edit | Copy XPath. The XPath/XQuery expression will be copied in JSON format to the clipboard. Press Ctrl+V to paste the locator expression to any text entry field.


For example, the following expression locates the title of the first track of the second album of the first artist in a YAML document:
