Use Sourcery to Generate bash script that will rewrite your source code to add final to all classes that have no inheritance

gistfile1.swifttemplate

#!/usr/bin/env bash
<% for type in types.classes { -%>
  <%_ if type.modifiers.map{ $0.name }.contains("final") || type.modifiers.map{ $0.name }.contains("open") || types.based[type.name].isEmpty == false { continue } -%>
<%_ _%>git grep -lz 'class <%= type.name %>' | xargs -0 perl -i'' -pE "s/class <%= type.name %>(?=\s|:)/final class <%= type.name %>/g"
<% } %>

// Run with Sourcery on your codebase and then execute generated code via bash :)

@Nikoloutsos @krzysztofzablocki I played a couple of hours and still can't run it. I had to fix an issue with EJS, but now, when Sourcery can finally find EJS dependency I get the following error

Rendering template Templates/Sourcery/FinalKeywordForClasses.ejs
error: Templates/Sourcery/FinalKeywordForClasses.ejs: SyntaxError: Invalid character: '#'
Templates/Sourcery/FinalKeywordForClasses.ejs: SyntaxError: Invalid character: '#'%

I used above snipped as FinalKeywordForClasses.ejs as template in
templates:

• ./Templates/Sourcery

What exactly did I do wrong?

This isn't EJS, it's Swift template as far as I remember @skerjie

Thanks a lot for clarification @krzysztofzablocki . But could you please in general describe how to run it.

when I run

sourcery --verbose --config sourcery.yml
I can see that processing happens

But how exactly run this swift template to add final keyword to files?
Thanks in advance

it generates a file as output, run it as bash script so need to add chmod +x and then ./generated-file-name

@skerjie It's been a while since I used this but I remember it was working fine.

@krzysztofzablocki , @Nikoloutsos thank you for your feedback. I still don't get the result that I want, but I strongly believe this is a working solution. Sourcery works for me extremely fine when I work with stencil templates especially since it is easy to do in Sourcery Pro, but for some reason, I couldn't achieve the same with this type of template. In the very best situation so far it's generated exactly the same script as the output but doesn't modify files ( I will try again

so you need to name it .swifttemplate run sourcery on it, if it sees your source files it should output a lot of lines for the command line grep / xargs pair, when you do so does it generate anything at all?

OMG. Finally, it did work. The problem was indeed in the file type .swifttemplate. @krzysztofzablocki thanks once again for the explanation, patience and help 🤝

glad it works now :)
