Question

Here is my code:

fs::path datadir = ...;
std::string dataDirOption((boost::format("--datadir=%1%") % datadir).str());

For datadir=="c:/db" I get dataDirOption=="--datadir=\"c:/db\"", instead of "--datadir=c:/db"

Is it possible to tell boost::filesystem::path to skip the quotes when being formatted?

Now, I know I can substitute datadir.string() for datadir and get rid of the quotes in this way, but I am wondering whether I can do so without the extra string.

Thanks.

Answer 1

I would suggest another option: post processing.

boost::replace_all(dataDirOption, "\"", "");

This way you can easily switch to another quote character like ' for example.
