Append Option

[drujensen]

Add the ability to append to the end of a file instead of skip/overwrite it.

I need this for only specific files in the templates. Specifically, I need to append to the config/routes.cr file.

maybe a file naming convention? If the file name ends with a + then it will append instead of overwrite?

I think it's a rare case. Instead of "append", how is "custom rendering" like this?

class Template < Teeplate::FileTree
  directory "/path/to/template"

  def overwrite_file(out_file, ...)
    if out_file == "config/routes.cr"
      overwrite_routes out_file, ...
    else
      super
    end
  end

  def overwrite_routes(out_file, ...)
    # ...
  end
end

Or, tell me more details about your story if you can.

@mosop Thanks for your response!

We are using two of your libraries to build a rails like generator for Kemalyst. They have been a huge help to this project. https://github.com/TechMagister/kemalyst-generator

To generate a resource, we need to inject the routes into the /config/routes.cr file. Your suggestion of overwriting the method should work fine. You are correct that this is a rare case and something we can handle in the Template class.

Thanks for the suggestion.

Thank you.

• How does the generator's user append a new route into the routes.cr?

• Can I see the routes.cr samples? I want to see:

  • a typical state before appending
  • a typical state after appending

Here is the routes.cr template when you create a new Kemalyst project: https://github.com/TechMagister/kemalyst-generator/blob/master/src/templates/app/config/routes.cr

Here is the scaffolding to add a new resource to the routes.cr: https://github.com/TechMagister/kemalyst-generator/blob/master/src/templates/scaffold/config/%2Broutes.cr.ecr

I solved this problem by re-opening the Entry.cr and looking for a + in the filename. If there is a +, then I strip the + and open the file as append: https://github.com/TechMagister/kemalyst-generator/blob/master/src/templates/entry.cr

Let me know if you have other suggestions on how to solve this.

[mosop]

Thank you. I'll think it over. Wait for a while.

Hi @drujensen, I added this feature into v0.3.0. It's almost the same as you want; You add a "+" sign into the head of filename and the file is written with "append mode". Try it!

[drujensen]

Awesome. Thanks!
