printCFG dont have documentation for CLI startup

[SwiftExtender]

I am trying to print CFG for specified file with command like

codeql database analyze testdb D:\codeql-main\csharp\ql\lib\printCfg.ql --external=selectedSourceColumn=line.txt --external=selectedSourceFile=File.txt --external=selectedSourceLine=column.txt --format=dot --output=test3 (testdb database is created and default rules work properly with it)

line.txt argument is a number of line, column.txt argument is a number of column, File.txt argument is a path to file with csharp code. After running i receive empty dot file. How to run this from CLI?

Hi @SwiftExtender 👋🏻

The printCfg.ql query is intended for internal use by the CodeQL extension for VSCode. I see you have asked about this previously and received an initial answer there. In your most recent reply there, you wrote that the suggestion didn't help, but can you explain what you tried and what happened?

The printCfg.ql query is not designed to be run manually with the CLI.

Perhaps you could talk about what you are generally trying to accomplish and then we can help you with that?

I want to get CFG graph for specified file. VS Code extension dont working and i prefer to get info by CLI command, as i see i need to set CfgScope somehow to get graph

I opened my repo with 50 MB of code and extension is loading extremely slow (progressbars in language and Databases windows show loading for several minutes) than i am trying to execute query like

import csharp

from Method fileOpen, MethodCall call
where fileOpen.hasQualifiedName("System.IO.File.Open")
  and call.getTarget() = fileOpen
select call.getArgument(0)

and i got error
