Format long ERB lines

[lcampanari]

Hey, thanks for this gem!

The readme says "attempts to limit length (configurable)". How can I configure that?

I tried running the following case in the command line

erb-formatter/test/erb/test_formatter.rb

Lines 126 to 136 in a710ec2

	def test_format_ruby
	assert_equal(
	"<div>\n" \
	" <%= render MyComponent.new(\n" \
	" foo: barbarbarbarbarbarbarbar,\n" \
	" bar: bazbazbazbazbazbazbazbaz\n" \
	" ) %>\n" \
	"</div>\n",
	ERB::Formatter.format("<div> <%=render MyComponent.new(foo:barbarbarbarbarbarbarbar,bar:bazbazbazbazbazbazbazbaz)%> </div>"),
	)
	end

with

echo "<div> <%=render MyComponent.new(foo:barbarbarbarbarbarbarbar,bar:bazbazbazbazbazbazbazbaz, baz:bahbahbahbahbahbahbahbabahbahbahbah, bah: fozfozfozfozfozfozfozfofzofzofzofozfozfozofz)%> </div>" | erb-format --stdin

and the result was

<div>
  <%= render MyComponent.new(foo:barbarbarbarbarbarbarbar,bar:bazbazbazbazbazbazbazbaz, baz:bahbahbahbahbahbahbahbabahbahbahbah, bah: fozfozfozfozfozfozfozfofzofzofzofozfozfozofz) %>
</div>

Is there anything I need to do in order to format long embedded ruby lines?

For now it can only be passed when used directly in Ruby (see below), but ideally there should be a CLI flag to set that number.
Happy to review a PR if you want to take up the challenge 🙌

NVM, I misread the issue, I think you can try the master version, which should contain a fix for that.
We'll release soon, so if that works just close this issue and wait for the update! Thanks for your patience 🙏

@elia I seem to be having an issue with 0.4.1 and long lines. (It might be related). I am doing the following bundle exec erb-format % --print-width 120 and the result are:

I would have expected the result to be:

As the line length of the longest line is only 99.

@cj just released v0.4.2, let me know if it doesn't work and we'll reopen 👍

@elia works perfectly, thank you so much!
