C++ HTML template framework, templatizing library, HTML generator library [closed]

Answer 1

I developed something here modeled after jade for c++. It takes a simple but powerful input language and creates a single c++ template function that writes HTML to a stream.

< html
  < h1 The title is ${{ params["title"] }}& >
    < ul >
    & for(int i = 0; i < boost::get<int>(params["items"]); ++i) {
      < li Item ${{ i }}$ >
    & }

• Variable replacement
• User defined code blocks
• harvests full power of c++ (loops, variable declarations, you name it)
• Super easy to integrate into source builds
• Everything possible done at compile time
• No intermediate format (straight c++)
• Easy to debug (because c++ output)
• No external dependencies
• Super tiny less than 600 lines of c++
• GPL licensed

Answer 2

Templtext is a small C++ text template processing library. It supports bash-like variables (%VAR or %{VAR}). But the main feature is a support of user defined functions. The library was created by me.

• Template parsing
• Variable replacement
• User defined functions in template
• C++11
• GPL license

need BOOST regex library, but it will be replaced with std::regex in the next version

Example 1:

using namespace templtext;

Templ * t = new Templ( "Dear %SALUTATION %NAME. I would like to invite you for %TEXT. Sincerely yours, %MYNAME." );

std::map<std::string, std::string> tokens01 =
{
        { "SALUTATION", "Mr." },
        { "NAME", "John Doe" },
        { "TEXT", "an interview" },
        { "MYNAME", "Ty Coon" }
};

std::map<std::string, std::string> tokens02 =
{
        { "SALUTATION", "Sweetheart" },
        { "NAME", "Mary" },
        { "TEXT", "a cup of coffee" },
        { "MYNAME", "Bob" }
};

std::cout << t->format( tokens01 ) << std::endl;
std::cout << t->format( tokens02 ) << std::endl;

Output:

Dear Mr. John Doe. I would like to invite you for an interview. Sincerely yours, Ty Coon.
Dear Sweetheart Mary. I would like to invite you for a cup of coffee. Sincerely yours, Bob.

Example 2:

using namespace templtext;

std::unique_ptr<Templ> tf1( new Templ( "You have got an $decode( 1 )." ) );
std::unique_ptr<Templ> tf2( new Templ( "You have got an $decode( 2 )." ) );
std::unique_ptr<Templ> tf3( new Templ( "English version - $decode_loc( 1, EN )." ) );
std::unique_ptr<Templ> tf4( new Templ( "German version  - $decode_loc( 1, DE )." ) );
std::unique_ptr<Templ> tf5( new Templ( "Flexible version - $decode_loc( 1, %LANG )." ) );

tf1->set_func_proc( func );
tf2->set_func_proc( func );
tf3->set_func_proc( func );
tf4->set_func_proc( func );
tf5->set_func_proc( func );

Templ::MapKeyValue map1 =
{
        { "LANG", "EN" }
};

Templ::MapKeyValue map2 =
{
        { "LANG", "DE" }
};

std::cout << tf1->format() << std::endl;
std::cout << tf2->format() << std::endl;
std::cout << tf3->format() << std::endl;
std::cout << tf4->format() << std::endl;
std::cout << tf5->format( map1 ) << std::endl;
std::cout << tf5->format( map2 ) << std::endl;

Output:

You have got an apple.
You have got an orange.
English version - apple.
German version  - Apfel.
Flexible version - apple.
Flexible version - Apfel.

Answer 3

Grantlee is a string template engine based on the Django template system. It is ported to C++/Qt.

Answer 4

facebook's format:

std::cout << format("The answers are {} and {}", 23, 42); 
// => "The answers are 23 and 42"

std::map<std::string, std::string> m { {"what", "answer"}, {"value", "42"} }; 
std::cout << vformat("The only {what} is {value}", m); 
// => "The only answer is 42"

Answer 5

Somehow I missed NLTemplate when I was searching originally, and wrote my own C++ templating engine, with apparently a similar use case as NLTemplate :-)

https://github.com/hughperkins/Jinja2CppLight

• Jinja2-like syntax
• lightweight, no dependencies on boost, qt, etc, ...
• variable substitution
• for loops
  • including nested for loops :-)

Answer 6

NLTemplate is a small C++ template library with syntax similar to Django.

• Variable replacement
• Repeatable or optional blocks
• File includes
• MIT licensed
• No external dependencies
• Single source file, easy to add to any project
