Syntax tree software

Question

Does anybody know a good software for creating syntax tree diagrams like this ?

Answer 1

For typesetting, the forest package for LaTeX is quite good, and has a lot of presets built in for linguistics purposes (syntax trees, autosegmental trees, etc).

Source:

[CP
    [CP
        [that]
        [TP
            [DP
                [{the fact that...},roof]
            ]
            [\ibar{T}
                [{is clear to all},roof]
            ]
(etc)

For simpler tasks, like making trees for answers here, I use jsSyntaxTree. It's not very customizable but is very fast and straightforward to use.

[TP [T might] [AuxP [Aux have] [vP [v+V gone] [V t]]]]

Finally, if you're looking to generate them programmatically (e.g. test a automatic parser by printing out the trees it generates), GraphViz is popular and has bindings for most programming languages.

   n002 [label="+"] ;
   n002 -- n003 ;
   n003 [label="*"] ;
   n003 -- n004 ;
   n004 [label="X"] ;
   n003 -- n005 ;
   n005 [label="-"] ;
   n005 -- n006 ;
(etc)
