escape all (not-already-escaped) double-quote chars in a string
// NOTE: only escapes a " if it's not already escaped
function escapeDoubleQuotes(str) {
return str.replace(/\\([\s\S])|(")/g,"\\$1$2"); // thanks @slevithan!
}
escapeDoubleQuotes(`ab`); // ab => ab (nothing escaped)
escapeDoubleQuotes(`a"b`); // a"b => a\"b
escapeDoubleQuotes(`a\\"b`); // a\"b => a\"b (nothing escaped)
escapeDoubleQuotes(`a\\\\"b`); // a\\"b => a\\\"b

Automatically manipulate .gitmodules so Travis CI pulls submodules from public URL instead of SSH URL.
#
# I use SSH URLs in my submodules for convenience. However, Travis CI is unable to
# clone from those URLs even though the repositories are public. To fix this, I'm
# simply manipulating the .gitmodules file with sed so it points to the public
# URLs before initializing the submodules.
#
# Hope it saves you some frustration!
#
# disable the default submodule logic
