Hi all,
talking with @ax3l and @n01r we thought it would be cool and useful to have WarpX dump an "evaluated" version of the used inputs on start, particularly when using text files as input.
It currently returns the "used input" file, but that only lists the input as they were requested in the file.
If some of the parameters are expressed using constants or mathematical expressions, the file returns the expression as it is.
Perhaps in addition to the file already dumped it would be useful to have one where constants and mathematical expressions are return evaluated so that it's possible to catch bugs related to their definition.
