func (*Compiler) SetIncludeDepthLimit ¶

func (c *Compiler) SetIncludeDepthLimit(limit int)

SetDebugLexer enables/disables printing of the token stream to stdout.

func (*Compiler) SetMaxErrors ¶

func (c *Compiler) SetMaxErrors(limit int)

SetMaxErrors sets the limit on the number of errors that can happen before the compiler gives up.

func (*Compiler) SetUsePush0 ¶

func (c *Compiler) SetUsePush0(on bool)

SetUsePush0 enables/disables use of the PUSH0 instruction. It's on by default.

type Position ¶
