Missing some line-breaks in output

[gperciva]

Thanks for this project!

On my system, I'm not seeing line-breaks where they should be, according to the tutorial. Taking example 5 from the tutorial,

from yattag import Doc

doc, tag, text, line = Doc().ttl()

with tag('ul', id='grocery-list'):
    line('li', 'Tomato sauce', klass="priority")
    line('li', 'Salt')
    line('li', 'Pepper')

print(doc.getvalue())

I get this output:

<ul id="grocery-list"><li class="priority">Tomato sauce</li><li>Salt</li><li>Pepper</li></ul>

whereas the tutorial says that I'll get nicely-formatted output with each <li> on a new line. (Or maybe that same output received manual line-breaks for readability?)

It's not a huge problem, since the HTML is rendered the same in both cases. Python 3.11.9, yattag 1.16.0.

Hello, if you need indentation, use the indent function.

from yattag import Doc, indent

doc, tag, text, line = Doc().ttl()

with tag('ul', id='grocery-list'):
    line('li', 'Tomato sauce', klass="priority")
    line('li', 'Salt')
    line('li', 'Pepper')

print(indent(doc.getvalue()))

You can read about the options of that function here: https://www.yattag.org/#indentation

Thanks for the clarification! My problem originated from a more complicated example, but I over-simplified it. After more investigation, it comes down to the indent_text argument.

Consider this example modified from example 9 "checkboxes and radio inputs":

from yattag import Doc, indent

doc, tag, text, line = Doc().ttl()

with tag('form', action = ""):
    line('p', 'Please pick the color of the spaceship')
    for color in ('blue', 'red', 'pink', 'yellow', 'ugly-yellow'):
        doc.input(name = 'color', type = 'radio', value = color)
        text(color)

    doc.stag('input', type = 'submit', value = 'Confirm my order')

print(indent(doc.getvalue(), indent_text = False)

I get:

<form action=""><p>Please pick the color of the spaceship</p><input type="radio" value="blue" name="color" />blue<input type="radio" value="red" name="color" />red<input type="radio" value="pink" name="color" />pink<input type="radio" value="yellow" name="color" />yellow<input type="radio" value="ugly-yellow" name="color" />ugly-yellow<input type="submit" value="Confirm my order" /></form>

If I change indent_text = True, then I get:

<form action="">
  <p>
    Please pick the color of the spaceship
  </p>
  <input type="radio" value="blue" name="color" />
  blue
  <input type="radio" value="red" name="color" />
  red
  <input type="radio" value="pink" name="color" />
  pink
  <input type="radio" value="yellow" name="color" />
  yellow
  <input type="radio" value="ugly-yellow" name="color" />
  ugly-yellow
  <input type="submit" value="Confirm my order" />
</form>

But that has a few more line-breaks than I was hoping for. The ideal would be something like the output that's in the tutorial:

<form action="">
  <p>Please pick the color of the spaceship</p>
  <input type="radio" value="blue" name="color" />blue
  <input type="radio" value="red" name="color" />red
  <input type="radio" value="pink" name="color" />pink
  <input type="radio" value="yellow" name="color" />yellow
  <input type="radio" value="ugly-yellow" name="color" />ugly-yellow
  <input type="submit" value="Confirm my order" />
</form>

(Interestingly, if I comment out the text(color) line, then I get my "desired" output -- although missing the actual color names, of course.
