enum VipsToken

Tokens returned by the vips lexical analyzer, see vips__token_get(). This is used to parse option strings for arguments.

Left and right brackets can be any of (, {, [, <.

Strings may be in double quotes, and may contain escaped quote characters, for example string, "string" and "str\"ing".
