Function Documentation

columnWidth()

unsigned clang::format::encoding::columnWidth ( StringRef  Text, Encoding  Encoding  )

inline

Returns the number of columns required to display the Text on a generic Unicode-capable terminal.

Text is assumed to use the specified Encoding.

columnWidthWithTabs()

unsigned clang::format::encoding::columnWidthWithTabs ( StringRef  Text, unsigned  StartColumn, unsigned  TabWidth, Encoding  Encoding  )

inline

Returns the number of columns required to display the Text, starting from the StartColumn on a terminal with the TabWidth.

The text is assumed to use the specified Encoding.

detectEncoding()

Encoding clang::format::encoding::detectEncoding ( StringRef  Text )

inline

Detects encoding of the Text.

If the Text can be decoded using UTF-8, it is considered UTF8, otherwise we treat it as some 8-bit encoding.

getCodePointNumBytes()

unsigned clang::format::encoding::getCodePointNumBytes ( char  FirstChar, Encoding  Encoding  )

inline

Gets the number of bytes in a sequence representing a single codepoint and starting with FirstChar in the specified Encoding.

Definition at line 77 of file Encoding.h.

References Encoding_UTF8.

getEscapeSequenceLength()

unsigned clang::format::encoding::getEscapeSequenceLength ( StringRef  Text )

inline

Gets the length of an escape sequence inside a C++ string literal.

Text should span from the beginning of the escape sequence (starting with a backslash) to the end of the string literal.
