crow::mustache Namespace Reference

In this namespace is defined most of the functions and classes related to template rendering. More...

Classes
class	invalid_template_exception
	Represents compilation error of an template. Throwed specially at mustache compile time. More...
struct	rendered_template
	Returned object after call the template_t::render() method. Its intended to be returned during a rule declaration. More...
struct	Action
	Used during mustache template compilation to represent parsing actions. More...
class	template_t
	Compiled mustache template object. More...

Typedefs
using	context = json::wvalue

Enumerations
enum class	ActionType {   Ignore , Tag , UnescapeTag , OpenBlock ,   CloseBlock , ElseBlock , Partial }
	Used in Action to represent different parsing behaviors. More...

Functions
template_t	load (const std::string &filename)
	Open, read and renders a file using a mustache compiler. It also sanitize the input before compilation.
template_t	compile (const std::string &body)
	The function that compiles a source into a mustache template.
std::string	default_loader (const std::string &filename)
	The default way that load, load_unsafe, load_text and load_text_unsafe use to read the contents of a file.
void	set_base (const std::string &path)
	Defines the templates directory path at route level. By default is templates/.
void	set_global_base (const std::string &path)
	Defines the templates directory path at global level. By default is templates/.
void	set_loader (std::function< std::string(std::string)> loader)
	Change the way that load, load_unsafe, load_text and load_text_unsafe reads a file. More...
std::string	load_text (const std::string &filename)
	Open, read and sanitize a file but returns a std::string without a previous rendering process. More...
std::string	load_text_unsafe (const std::string &filename)
	Open and read a file but returns a std::string without a previous rendering process. More...
template_t	load_unsafe (const std::string &filename)
	Open, read and renders a file using a mustache compiler. But it do not sanitize the input before compilation. More...

Detailed Description

In this namespace is defined most of the functions and classes related to template rendering.

If you are here you might want to read these functions and classes:

• template_t
• load_text
• load_text_unsafe
• load
• load_unsafe

As name suggest, crow uses mustache as main template rendering system.

You may be interested in taking a look at the Templating guide page.

Function Documentation

load_text()

std::string crow::mustache::load_text ( const std::string &  filename )

inline

Open, read and sanitize a file but returns a std::string without a previous rendering process.

Except for the sanitize process this function does the almost the same thing that load_text_unsafe.

load_text_unsafe()

std::string crow::mustache::load_text_unsafe ( const std::string &  filename )

inline

Open and read a file but returns a std::string without a previous rendering process.

This function is more like a helper to reduce code like this...

std::ifstream file("home.html");
return std::string({std::istreambuf_iterator<char>(file), std::istreambuf_iterator<char>()});

... Into this...

return load("home.html");

Warning

Usually load_text is more recommended to use instead because it may prevent some XSS Attacks. Never blindly trust your users!

load_unsafe()

template_t crow::mustache::load_unsafe ( const std::string &  filename )

inline

Open, read and renders a file using a mustache compiler. But it do not sanitize the input before compilation.

Warning

Usually load is more recommended to use instead because it may prevent some XSS Attacks. Never blindly trust your users!

set_loader()

void crow::mustache::set_loader ( std::function< std::string(std::string)>  loader )

inline

Change the way that load, load_unsafe, load_text and load_text_unsafe reads a file.

By default, the previously mentioned functions load files using default_loader, that only reads a file and returns a std::string.
