Pos computes the source position of the declaration of an object name. The result may be an invalid position if it cannot be computed (obj.Decl may be

Pos returns the Pos value for the given file offset; the offset must be <= f.Size(). f.Pos(f.Offset(p)) == p.

Position converts a Pos in the fileset into a general Position.

Print prints x to standard output, skipping nil fields. Print(fset, x) is the same as Fprint(os.Stdout, fset, x, NotNilFilter).

PrintError is a utility function that prints a list of errors to w, one error per line, if the err parameter is an ErrorList. Otherwise it prints the

Read calls decode to deserialize a file set into s; s must not be nil.

RemoveMultiples sorts an ErrorList and removes all but the first error per line.

Reset resets an ErrorList to no errors.

SetLines sets the line offsets for a file and returns true if successful. The line offsets are the offsets of the first character of each line; for in

SetLinesForContent sets the line offsets for the given file content.

SortImports sorts runs of consecutive import lines in import blocks in f. It also removes duplicate imports when it is possible to do so without data

Debugging support

String returns a string in one of several forms: file:line:column valid position with file name line:column valid position without file

Update replaces an old node in the comment map with the new node and returns the new node. Comments that were associated with the old node are associa

Write calls encode to serialize the file set s.

bodySize is like nodeSize but it is specialized for *ast.BlockStmt's.

This allows '\n' since is needed for indenting tracks

commonPrefix returns the common prefix of a and b.

declNode() ensures that only declaration nodes can be assigned to a DeclNode.

distanceFrom returns the column difference between from and p.pos (the current estimated position) if both are on the same line; if they are on differ

---------------------------------------------------------------------------- Export filtering exportFilter is a special filter function to extract exp

exprNode() ensures that only expression/type nodes can be assigned to an ExprNode.

Returns true if s contains only white space (only tabs and blanks can appear in the printer's context).

Returns true if s contains only white space (only tabs and blanks can appear in the printer's context).

specNode() ensures that only spec nodes can be assigned to a Spec.

stmtNode() ensures that only statement nodes can be assigned to a StmtNode.

syncDecl advances to the next declaration. Used for synchronization after an error.
