Preserving comments

[qqwwaass]

When I write a configuration to disk using "void writeFile(const char *filename);" comments are not preserved. This is a problem, because I'd like to edit files both with a text editor and libconfig (from a C++ program).
Is it possible to preserve comments?

Not with the current implementation, and this is by design. Please check the (fine) documentation, section 2.10:
"text.
Comments are ignored when the configuration is read in, so they are not treated as part
of the configuration. Therefore if the configuration is written back out to a stream, any
comments that were present in the original configuration will be lost."

This would be very hard to implement since comments can appear virtually anywhere in the configuration. I did consider some limited support for saving any comment that appeared directly before a setting, by attaching its text to the setting itself. So effectively every setting would have a "comment" property.

Just extend the config_setting_t structure to have "comment" property.
Each setting parse to the end of line. All the text after ';' mark that is detected as one line comment ("//" or "#") will be added to the property.

At the moment Iam using the lib like this to save comments which is ugly way:
pos_x = 5;
pox_x_comment = "This is comment";
