String Right

String Right returns the last N characters of a string - Excel's RIGHT, ported to a node. It's the bookend of the slicing trio (Left / Mid / Right) in the TakkunRed ComfyUI-String-Function pack, and it's the natural tool for the "tail" of anything: file extensions, trailing IDs, the end of a filename that carries the meaningful bit.

In practice it earns its keep on things like image_00042.png → take the last 3 for png, or a generated string where the version tag always sits at the end. When the interesting part of your text is anchored to the end rather than the start, Right beats Left-and-then-reverse, because there's no reversing at all.

How it works

One Python slice: text[-num_chars:], with the guard that num_chars=0 returns an empty string instead of the whole string (which is what text[-0:] would naively give you). The author handled that edge case explicitly, which is a small sign of care. Slices clamp, so asking for more characters than the string has just returns the whole thing.

Like its siblings, num_chars counts characters, not bytes - multibyte text slices along character boundaries as a human reads them, not along raw byte offsets.

Inputs and outputs

Two required inputs: text and num_chars (INT, default 1, 0–99999). One output: result (STRING).

Nothing else to configure. It's a pure transform, the kind of node you drop into a chain and forget about.

Installing it

Same pack, same zero-dependency install:

cd ComfyUI/custom_nodes
git clone https://github.com/TakkunRed/ComfyUI-String-Function

Or search "ComfyUI-String-Function" in ComfyUI Manager, restart, and it's under String Function.

Where people get burned

• It's the last N characters, not the last "word" or "segment." The classic trap: grabbing a file extension with num_chars=3 from photo.jpeg gives you jpeg - fine - but from photo.png you get png - also fine - and from archive.tar.gz you get .gz, not tar.gz. If you want the part after the last dot, that's a Split on . with use_last=True, not a Right.
• Trailing whitespace counts. If your upstream text has a stray newline, it eats a character of your count. A String Trim upstream fixes that.
• There's no "last 5 non-space characters" mode - the count is literal.

It's a three-line node, and that's the point: when you need the tail, this is the two-second answer, and it composes cleanly with String Find and Mid for anything fancier.
