Source references from the parser
...eans bytes, but I haven't tested with MBCSs) in a source file. It is implemented as a vector of 4 integers (first line, first column, last line, last column), with the srcfile as an attribute. The parser attaches a srcref attribute to each complete statement as it gets parsed, if option("useSource") is TRUE. (I've left the old source attribute in place as well for functions; I think it won't be needed in the long run, but it is needed now.) When printing an object with a srcref attribute, print.default tries to read the srcfile to obtain the text. If it fails, it falls back...

parse(text=...) and the srcfile attribute
...2**2 a + b ") I now wish to recover the sources for the parsed expressions. I can get them one at a time: > foo[[2]] b <- 2^2 > as.character(attr(foo, "srcref")[[2]]) [1] "b <- 2**2" Is there a better way? Perhaps like the print method > as.character(foo, useSource = TRUE) could give all the sources at once? -Deepayan
