Hi Raphael,
no, I need an empty line after Uitl.eol, before any other text. But you bring up an interesting point, that my lens doesn't recognize the end of a file, which could be accepted all the same, without requiring an actual empty line. But how can I match the end of a file? Ciao, Xavier.

It's common to end every line with a Util.eol, which defaults to a newline. Or do you mean that you need an empty line at the end of the file?

Also, relying on Augeas users to do this just to insert a line break, which is required for a valid configuration file, is ugly and error prone. This workaround still may be used to add additional empty lines to a configuration file just to improve readability (where they don't break anything), so still a useful lesson. Though for my custom lens, I have decided to look for and create empty lines by default, as with any string literal. This way, the Augeas tree doesn't need to feature empty nodes and empty lines will be added in put direction automatically. Thank you again for your time, Xavier.

Hello Xavier, I was going to say that was not possible, but I actually (to my great surprise) found a way to do it: augtool> touch /files/etc/fstab/01 augtool> rename /files/etc/fstab/01 "" rename : /files/etc/fstab/01 to 1 augtool> save Saved 1 file(s) Just added an empty line at the end of /etc/fstab Cheers, Raphaël On Tue, Dec 22, 2015 at 10:06 AM, Mol, Xavier (SCC) <xavier....@kit.edu> wrote: Hello Augeas experts, is there a way to insert empty nodes in an Augeas tree? I've made a lens, that expects an empty line as last part (Util.empty), which works fine with existing files. However, when inserting a new node in the tree with that lens, the closing empty line is missing. Do I need to have a labelled node in the tree without value or children, that simply puts an empty line in the resulting string instead?
