Function Documentation

ClassifyHyperlink()

static HyperlinkType ClassifyHyperlink ( const std::string &  destination, bool  trusted  )

static

Classify the type of hyperlink the destination describes.

Parameters

destination	The hyperlink destination.
trusted	Whether we trust the content of this file.

Returns

HyperlinkType The classification of the link.

GetTextfile()

std::optional<std::string> GetTextfile	(	TextfileType	type,
		Subdirectory	dir,
		const std::string &	filename
	)

Search a textfile file next to the given content.

Parameters

type	The type of the textfile to search for.
dir	The subdirectory to search in.
filename	The filename of the content to look for.

Returns

The path to the textfile, nullptr otherwise.

Gunzip()

static void Gunzip ( byte **  bufp, size_t *  sizep  )

static

Do an in-memory gunzip operation.

This works on a raw deflate stream, or a file with gzip or zlib header.

Parameters

bufp	A pointer to a buffer containing the input data. This buffer will be freed and replaced by a buffer containing the uncompressed data.
sizep	A pointer to the buffer size. Before the call, the value pointed to should contain the size of the input buffer. After the call, it contains the size of the uncompressed data.

When decompressing fails, *bufp is set to nullptr and *sizep to 0. The compressed buffer passed in is still freed in this case.

MakeAnchorSlug()

static std::string MakeAnchorSlug ( const std::string &  line )

static

Create a valid slug for the anchor.

Parameters

line	The line to create the slug for.

Returns

std::string The slug.

Definition at line 203 of file textfile_gui.cpp.

Xunzip()

static void Xunzip ( byte **  bufp, size_t *  sizep  )

static

Do an in-memory xunzip operation.

This works on a .xz or (legacy) .lzma file.

Parameters

bufp	A pointer to a buffer containing the input data. This buffer will be freed and replaced by a buffer containing the uncompressed data.
sizep	A pointer to the buffer size. Before the call, the value pointed to should contain the size of the input buffer. After the call, it contains the size of the uncompressed data.

When decompressing fails, *bufp is set to nullptr and *sizep to 0. The compressed buffer passed in is still freed in this case.
