Feature/updated cpptoml

[dpastoor]

just wanted to pass along, tried it out, works beautifully!

For those that come along and would like an example,

example_string <- "
[[test]]
var1 = 'hello'
var2 = 2
var3 = '''
some
multiline string
'''
[test2]
date = 1970-01-01
"

RcppTOML::parseTOML(example_string, fromFile = F)

which gives

@eddelbuettel any reason why the print method gives a trailing NULL value?

Even when saving to an object, when querying the object, it always has that trailing NULL

output <- RcppTOML::parseTOML(example_string, fromFile = F)

> output
List of 2
 $ test :List of 3
  ..$ var1: chr "hello"
  ..$ var2: int 2
  ..$ var3: chr "some\\nmultiline string\\n"
 $ test2:List of 1
  ..$ date: Date[1:1], format: "1970-01-01"
NULL

Just in case:

[eddelbuettel]

We use str() inside the print() and I dont't know how to not make it show NULL.

[eddelbuettel]

This seems to work better:

print.toml <- function(x, ...) { cat(utils::str(x, give.attr=FALSE)); invisible(x) }

Now:

R> z
List of 2
 $ test :List of 3
  ..$ var1: chr "hello"
  ..$ var2: int 2
  ..$ var3: chr "some\\nmultiline string\\n"
 $ test2:List of 1
  ..$ date: Date[1:1], format: "1970-01-01"
R> print(z)
List of 2
 $ test :List of 3
  ..$ var1: chr "hello"
  ..$ var2: int 2
  ..$ var3: chr "some\\nmultiline string\\n"
 $ test2:List of 1
  ..$ date: Date[1:1], format: "1970-01-01"
R> 

I'll make the change.
