Simple C++ ini parser.

Writing comments

I came across this project and like its compactness. I was wondering... for the generation feature, is it possible to generate comments? I couldn't see an easy way to do it without modification. I see it ignores them on parsing, but not that it can write them.

Thanks!

Support comments behind a line

Hey,

You don' support comments behind a line yet.
Example:

[general]
some_field = some_value ; Comment

Compile error with C++17, ptr_fun deprecated

Hey,

the ltrim/rtrim implementations generate compile errors for me with C++17 as a language standard because std::ptr_fun is deprecated since C++11 and finaly removed in 17. Do you mind changing this to a lambda, i.e. the full implementation of ltrim would then become:

template <class CharT> inline void ltrim(std::basic_string<CharT> & s) { s.erase(s.begin(), std::find_if(s.begin(), s.end(), [](int c) {return !std::isspace(c); })); }

I can also do a PR if you like.

Bump cmake version to 2.8.12

Allow new line to be inserted between sections in generate() output

Currently, the generated output writes all sections with no new lines between them.

Would be nice (for cosmetic reasons) to have the option to separate each section by a new line.

How to set a value

How to set a value?
something like inipp::get_value(); but to set a value would be great
Thanks.

Why is the data type of sections std::map, not std::ordered_map?

If is there a reason, could you explain why?

Default value for std::string

Hello,

First of all, thank you for inipp, it is very lightweight and I think, very elegant.

I have an issue when trying to simulate 'default values' for std::string.

For example, if I insert those lines in example.cpp, with the same example.ini,
where Usera is not defined :

std::string user = "testUser";
inipp::extract(ini.sections["bitbucket.org"]["Usera"], user);
std::cout << "bitbucket.org user: " << user << std::endl;

the output contains:

bitbucket.org user:

instead of what I would have expected:

bitbucket.org user: testUser

While looking why in the source code I found that my test uses this template specialization:

template <typename CharT>
inline bool extract(const std::basic_string<CharT> & value, std::basic_string<CharT> & dst) {
	dst = value;
	return true;
}

So it is clear why my default string became an empty string.

Would it be possible to have the same feature as integer or boolean ?

• return false if no match
• not changing the existing value

Please tell me if I could help.

Thank you.

I get a 0 instead of 0.87 in my parsing of a Real number.

In this project:
https://github.com/Danielgb23/EA872-projeto
If I configure the config/player.ini attack_rate to 0.87 for example the parser reads it as a 0 which leads to a division by zero later on in the code.

It's read in this line of the code:
attack_rate = reader.GetReal("stats", "attack_rate", -1);
At the line 49 of src/model/entity.cpp. I checked it out with GDB and it really reads it as zero. If I change to other number it reads it normally. Real numbers like 4.3 are read normally (actually they change to 4.299999 or something like that).

Bug: Comments are treated as value

Hi,

I've just modified the test1.ini file to

[section] 
variable="value" ;dummy

Output in test1.output should be

>>> ERRORS <<<
>>> GENERATE <<<
[section]
variable=value

>>> INTERPOLATE <<<
[section]
variable=value

However the output from the library is:

>>> ERRORS <<<
>>> GENERATE <<<
[section]
variable=value ;dummy

>>> INTERPOLATE <<<
[section]
variable=value ;dummy

[Feature request] Add CMake support

Maybe someone would be willing to add proper CMake support which means to at least define an INTERFACE library as target.
