## Formatted String
|
|
|
|
|
|
|
|
(ComfyUI workflow included)
|
|
|
|
Creates a string that contains placeholder variables and replaces them with their respective values.
|
|
Uses python `str.format()` internally, see [Python - Format String Syntax](https://docs.python.org/3/library/string.html#format-string-syntax) .
|
|
* You can use `{a:.2f}` to round off a float to 2 decimals.
|
|
* You can use `{a:05d}` to pad up to 5 leading zeros to fit with comfys filename suffix `ComfyUI_00001_.png`.
|
|
* If you want to write `{ }` within your strings (e.g. for JSONs) you have to double them: `{{ }}`.
|
|
|
|
Also applies *search & replace (S&R) syntax* such as `%date:yyyy-MM-dd hh:mm:ss%` and `%KSampler.seed%`.
|
|
Thus you can also use it as a `GET-node`.
|
|
Note that "search & replace" takes place in Javascript context and runs before node execution.
