Convert BibTeX string to data frame using temporary file

This function converts a BibTeX formatted string into a data frame by writing the string to a temporary file and then using bib2df::bib2df to parse it. The temporary file is automatically cleaned up after use.

Usage

bib_string2df_alt(string, ...)

Arguments

string

A BibTeX formatted string containing one or more entries

...

Additional arguments passed to bib2df::bib2df()

Value

A tibble/data frame with parsed BibTeX entries

Details

This approach uses temporary files to work around the limitation that bib2df::bib2df only accepts file paths, not strings directly. The temporary file is created in the system temp directory and removed automatically, even if an error occurs.
