Meziantou.FrameworkShellSyntaxRewriter Class
Builds a new tree by visiting an old one and returning replacements.
public class ShellSyntaxRewriter : ShellSyntaxVisitor<SyntaxNode?>Remarks
A node whose parts all come back unchanged is returned as it was, so rewriting a tree and changing nothing in it costs nothing and keeps every node.
Example
private sealed class RenameCommand : ShellSyntaxRewriter
{
public override SyntaxNode? VisitCommand(ShellCommandSyntax node)
{
if (node.Name is { } name && node.NameValue == "ls")
return node.ReplaceNode(name, name.WithText("dir"));
return base.VisitCommand(node);
}

VisitToken(SyntaxToken)
ShellSyntaxRewriter.csRewrites a token, putting the trivia around it through ShellSyntaxRewriter.VisitTrivia.
public virtual SyntaxToken VisitToken(SyntaxToken token)Parameters
tokenSyntaxToken
Returns
Remarks
Nothing else reaches a token's trivia, so an override of ShellSyntaxRewriter.VisitTrivia would never be called if this returned the token untouched. A rewrite that returns the default trivium removes it.
