Below the keywords starts the snippet which gets expanded. After the snippet
expansion you can jump to the placeholders and replace them with desired text.
The snippet itself starts below the part that contains the options, snippet
aliases and kekywords, described above. It contains the snippet which gets
expanded and can contain several place holders. The placeholders are used as
jump points inside the snippet. There are several placeholder available and they
provide diffrent functionality.
The structure of a placeholder can be:
- ${number:placeholder text}
Here the number of the placeholder and the placeholder text that are
separated by a ":" are embraced by a pair of "{}". The text is displayed
after the snippet expansion and gets replaced by your text. If you jump
over the snippet and do not insert any text in that position the
placeholder text remains there. This can be used as a standard value for a
certain position.
