Adding "true" and "false" strings to Bottle produces unwanted quotation marks

[gsaponaro]

I have a module that needs to add the words true/false (actual strings, not boolean values) to a Bottle. However I observed that adding the strings true and false to a Bottle then printing it on screen shows quotation marks around these words, while other strings show no quotes. I guess it has to do with true and false being reserved keywords in C++.

Example:

Bottle bottle;
bottle.addString("word1"); 
bottle.addString("true");
bottle.addString("any_other_word");
cout << bottle.toString().c_str() << endl;

prints word1 "true" any_other_word <-- notice quotation marks around true. Is it possible to obtain word1 true any_other_word instead?

In the end, this is not really a problem for our project: the client that reads the Values from my Bottle works whether those quotation marks are present or not.

However, I am still curious about this behaviour, if it is expected of yarp to put those quotes around true/false, do you know @paulfitz @drdanz?

Please feel free to close this issue when you want.

I think this behavior is to keep unquoted true/false free for eventual json compatibility. When converting the entire bottle, each element is serialized in a way that lets it be read again as the original type. You could ask bot.get(1).asString() if you expect a string, and there will be no quoting. Sorry for the confusion and delay responding.

Thank you, no problem.
