#include "quote.h"

int main(int argc, const char * argv[]) {
     // all Yahoo! Finance quote types are implemented (this is just a sample)
    std::string petr4Quotes = quote::getLatestQuotesCsv("petr4.sa", {quote::QuoteType::symbol,
                                                                     quote::QuoteType::name,

quote depends on libcurl to build (http://www.curl.haxx.se/libcurl/).

quote is thread safe provided the following observation:

Manual curl initialization (curl_global_init) must be performed before using quote functions in a multi-threaded context, otherwise it can be ignored. Check http://curl.haxx.se/libcurl/c/curl_easy_init.html.

quote builds on Linux and MacOSX (Windows has not been tested yet). It requires a C++11 compatible compiler. The library has been successfully built with:

• Apple LLVM version 5.0; and
• gcc (Debian 4.7.2-5) 4.7.2

Modify common.mk for quote install configuration.

Any of the following make invocations can be executed with the -j option (make -j) for parallel compilation (builds faster).

To build the library:

$ make

The shared and static library files will be on src/ directory. The include files needed to use quote are on src/ directory.

To install:

$ sudo make install

To uninstall:

$ sudo make uninstall

To build the samples:

$ make samples

To clean everything compiled (including samples):

$ make clean

Set the compiler standard to C++11, include quote headers in the search path and link to its library. E.g:

compiler flags: `-std=c++11 -I/usr/local/quote`
linker flags: `-L/usr/local/lib -lquote`

Include the library header quote.h (namespace quote).

Check the samples directory for examples.

See doc/html/index.html for the doxygen generated quote API reference.
