O2 Tool – AST Search (.NET Static Analysis)

Here is a very useful tool built on top of O2‘s AST-base static analysis engine.

The tool is is called ‘Search AST’ and allows for ‘AST based’ searches of C# source code files.

How to use this tool

• On main O2 Gui, in the ‘Custom O2s’ tab, click on the ’DotNet Static Analysis’ button:

• Then on the ‘AST & PoCS’ tab , click on the ‘ascx_SearchAST’  button:

• This will open a gui that looks like this:

• Now find the folder with the C# source code to analyse and drag & Drop it into the rigth-left treeview

• Once that loads up, you can select on the INode types on the left to see the cases where they show up

• You can do searches on the selected INode type (in this find searching for WebMethod in the Attribute INodes)

• and you can also do a global search on ALL INodes

• the list show on the Search Result TreeView is the unique list of string matches

• and the list that is show on the ‘Source Code Lines’ Treeview is a list of the source code lines that match the current selected item
