write TOML files?

[shabbybanks]

Maybe this is out of scope, but it would be nice to write a list to a TOML file. I think the upstream cpptoml library has an example program of serializing an object to a stream (examples/build_toml.cpp). Perhaps that can be ported without too much headache.

[eddelbuettel]

Yes. Opening a filestream is easy.

The problem is that the 'mental model' I have of toml files has copious comments. And those we don't have. Hence, the read/write cycle can not be idempotent.

[shabbybanks]

Perhaps the read & write operations can be pseudo inverses of each other in the sense that read-write-read gives the same results as read, and write-read-write gives the same results as write.

Another option would be to allow a comment attribute of a field to be written out as a comment in the YAML file, though that would break the pseudo-inverse property.

Ah. Had not made that connection.

[shabbybanks]

there is no connection.

[eddelbuettel]

Of course not. Silly me.

We are about to release an updated version based on toml++ which could write TOML files. I however have no current use case but external contributions may be considered. Until then I close this as stale.
