Fdump dumps the structure of the syntax tree rooted at n to w.

MakePos returns a new Pos for the given PosBase, line and column.

NewFileBase returns a new PosBase for the given filename.

NewLineBase returns a new PosBase for a line directive "line filename:line:col" relative to pos, which is the position of the character immediately following the comment containing the line directive.

Parse parses a single Go source file from src and returns the corresponding syntax tree.

ParseFile behaves like Parse but it reads the source from the named file.

Error describes a syntax error.

package PkgName; DeclList[0], DeclList[1], ...

All declarations belonging to the same group point to the same Group node.

A Pos represents an absolute (line, col) source position with a reference to position base for computing relative (to a file, or line directive) position information.

A PosBase represents the base for relative position information: At position pos, the relative position is filename:line:col.

TODO(gri) Consider renaming to CommentPos, CommentPlacement, etc.

An ErrorHandler is called for each error encountered reading a .go file.

Mode describes the parser mode.

A Pragma value is a set of flags that augment a function or type declaration.

A PragmaHandler is used to process //go: directives as they're scanned.
