add spec for require_relative

[kakubin]

just add spec

background

on rails application(7.1.3.2) with Ruby 3.3, I met an issue with code below.

# bin/ridgepole(+x)
#!/usr/bin/env ruby
require 'ridgepole'
require 'ridgepole/cli/config'

path = 'Schemafile'
env = ENV['RAILS_ENV'] || 'development'

client = Ridgepole::Client.new(Ridgepole::Config.load('config/database.yml', env))
dsl = File.read(path)
delta = client.diff(dsl) # <= `path` is not passed
delta.migrate if delta.differ?

# ./Schemafile
require_relative './lib/ridgepole/my_customize'

$ bin/ridgepole
<internal:/Users/kakubin/.rbenv/versions/3.3.1/lib/ruby/3.3.0/rubygems/core_ext/kernel_require.rb>:37:in `require': cannot load such file -- /Users/kakubin/sample-rails-application/(eval at /Users/kakubin/ridgepole/lib/ridgepole/dsl_parser/lib/ridgepole/my_customize (LoadError)

And this is how values were resolved in the method require_relative.

irb(#<Ridgepole::DSLParser::Conte...):001:0> File.dirname(caller[0])
=> "/Users/kakubin/.rbenv/versions/3.3.1/lib/ruby/gems/3.3.0/gems/irb-1.12.0/lib/irb"
irb(#<Ridgepole::DSLParser::Conte...):002:0> File.expand_path(relative_path, File.dirname(caller[0]))
=> "/Users/kakubin/.rbenv/versions/3.3.1/lib/ruby/gems/3.3.0/gems/irb-1.12.0/lib/irb/lib/ridgepole/my_customize"

Because of lack of an argument path for Ridgepole::Client#diff, Schemafile is evaluated under (eval) and caller[0] return anything but 'Schemafile'.

ridgepole/lib/ridgepole/dsl_parser/context.rb

Lines 14 to 21 in 0481fdf

	def self.eval(dsl, opts = {})
	ctx = new(opts)
	if opts[:path]
	ctx.instance_eval(dsl, opts[:path])
	else
	ctx.instance_eval(dsl)
	end

To fix it, I just have to add argument path and no need to modify Ridgepole::DSLParser::Context in conclusion.

this issue is not reproduced with ruby 3.2 or below.

Could you please tell me why you want to make such a change?
It would be helpful if you could tell me the actual problem.
