Static functions

configKeyGet

string configKeyGet(string key)

Do not use. Does not do anything.

configKeyGetSystem

string configKeyGetSystem(string key)

Do not use. Does not do anything.

getLibSubdirectory

string getLibSubdirectory()

Returns the name of the "pango" subdirectory of LIBDIR (which is set at compile time).

getSysconfSubdirectory

string getSysconfSubdirectory()

Returns the name of the "pango" subdirectory of SYSCONFDIR (which is set at compile time).

isZeroWidth

bool isZeroWidth(dchar ch)

Checks @ch to see if it is a character that should not be normally rendered on the screen. This includes all Unicode characters with "ZERO WIDTH" in their name, as well as <firstterm>bidi</firstterm> formatting characters, and a few other ones. This is totally different from g_unichar_iszerowidth() and is at best misnamed.

log2visGetEmbeddingLevels

ubyte* log2visGetEmbeddingLevels(string text, int length, PangoDirection* pbaseDir)

This will return the bidirectional embedding levels of the input paragraph as defined by the Unicode Bidirectional Algorithm available at:

lookupAliases

void lookupAliases(string fontname, string[] families)

Look up all user defined aliases for the alias @fontname. The resulting font family names will be stored in @families, and the number of families in @n_families.

parseEnum

bool parseEnum(GType type, string str, int value, bool warn, string possibleValues)

Parses an enum type and stores the result in @value.

parseStretch

bool parseStretch(string str, PangoStretch stretch, bool warn)

Parses a font stretch. The allowed values are "ultra_condensed", "extra_condensed", "condensed", "semi_condensed", "normal", "semi_expanded", "expanded", "extra_expanded" and "ultra_expanded". Case variations are ignored and the '_' characters may be omitted.

parseStyle

bool parseStyle(string str, PangoStyle style, bool warn)

Parses a font style. The allowed values are "normal", "italic" and "oblique", case variations being ignored.

parseVariant

bool parseVariant(string str, PangoVariant variant, bool warn)

Parses a font variant. The allowed values are "normal" and "smallcaps" or "small_caps", case variations being ignored.

parseWeight

bool parseWeight(string str, PangoWeight weight, bool warn)

Parses a font weight. The allowed values are "heavy", "ultrabold", "bold", "normal", "light", "ultraleight" and integers. Case variations are ignored.

quantizeLineGeometry

void quantizeLineGeometry(int thickness, int position)

Quantizes the thickness and position of a line, typically an underline or strikethrough, to whole device pixels, that is integer multiples of %PANGO_SCALE. The purpose of this function is to avoid such lines looking blurry.

readLine

int readLine(FILE* stream, StringG str)

Reads an entire line from a file into a buffer. Lines may be delimited with '\n', '\r', '\n\r', or '\r\n'. The delimiter is not written into the buffer. Text after a '#' character is treated as a comment and skipped. '\' can be used to escape a # character. '\' proceeding a line delimiter combines adjacent lines. A '\' proceeding any other character is ignored and written into the output buffer unmodified.

scanInt

bool scanInt(string pos, int output)

Scans an integer. Leading white space is skipped.

scanString

bool scanString(string pos, StringG output)

Scans a string into a #GString buffer. The string may either be a sequence of non-white-space characters, or a quoted string with '"'. Instead a quoted string, '\"' represents a literal quote. Leading white space outside of quotes is skipped.

scanWord

bool scanWord(string pos, StringG output)

Scans a word into a #GString buffer. A word consists of [A-Za-z_] followed by zero or more [A-Za-z_0-9] Leading white space is skipped.

skipSpace

bool skipSpace(string pos)

Skips 0 or more characters of white space.

splitFileList

string[] splitFileList(string str)

Splits a %G_SEARCHPATH_SEPARATOR-separated list of files, stripping white space and substituting ~/ with $HOME/.

trimString

string trimString(string str)

Trims leading and trailing whitespace from a string.
