Function Documentation

GetEnv()

template<typename T >

T tvm::support::GetEnv ( const char *  key, T  default_value  )

inline

Get environment variable with a typed default value.

Template Parameters

T	The value type (must be arithmetic or std::string).

Parameters

key	The environment variable name.
default_value	The value to return if the variable is unset or empty.

Returns

The parsed value or the default.

GetFileFormat()

ffi::String tvm::support::GetFileFormat ( const ffi::String &  path, const ffi::String &  format  )

inline

Get the explicit format, or the extension of the file path.

ReadBytesFromFile()

ffi::Bytes tvm::support::ReadBytesFromFile ( const ffi::String &  path )

inline

Read a file as binary bytes.

StrEscape() [1/2]

std::string tvm::support::StrEscape ( const char *  data, size_t  size, bool  use_octal_escape = false, bool  escape_whitespace_special_chars = true  )

inline

Create a stream with escape.

Parameters

data	The data
size	The size of the string.
use_octal_escape	True to use octal escapes instead of hex. If producing C strings, use octal escapes to avoid ambiguously-long hex escapes.
escape_whitespace_special_chars	If True (default), escape any tab, newline, and carriage returns that occur in the string. If False, do not escape these characters.

Returns

the Result string.

StrEscape() [2/2]

std::string tvm::support::StrEscape ( const std::string &  val, bool  use_octal_escape = false, bool  escape_whitespace_special_chars = true  )

inline

Create a stream with escape.

Parameters

val	The C++ string
use_octal_escape	True to use octal escapes instead of hex. If producing C strings, use octal escapes to avoid ambiguously-long hex escapes.
escape_whitespace_special_chars	If True (default), escape any tab, newline, and carriage returns that occur in the string. If False, do not escape these characters. If producing python strings with """triple quotes""", do not escape these characters.

Returns

the Result string.

WriteBytesToFile()

void tvm::support::WriteBytesToFile ( const ffi::String &  path, const ffi::Bytes &  data  )

inline

Write binary bytes to a file.
