[flywire]

Describe the bug

context You can configure. The can should be demonstrated.

expectation Install should produce 3rd example. Requires a Minimal Working Example.

bug Default install strips nothing

problem Example is non-functional

Reproduce the bug

1. Default install
2. Select Copy button
3. Paste does not strip prompts and output

List your environment

Python 3.10.2 (tags/v3.10.2:a58ebcc, Jan 17 2022, 14:12:15) [MSC v.1929 64 bit (AMD64)] on win32 Running Sphinx v6.2.1

Example at https://sphinx-copybutton.readthedocs.io/:

>>> a = 2
>>> print(a)
2
>>>
>>> b = 'wow'
>>> print(b)
wow

copy/paste gives:

a = 2
print(a)
b = 'wow'
print(b)

Blank lines are an important part of code and should not be stripped or require Using regexp prompt identifiers.

---

These two parts as documented don't work together:

https://sphinx-copybutton.readthedocs.io/en/latest/use.html#automatic-exclusion-of-prompts-from-the-copies

... To make sphinx-copybutton skip all prompt characters generated by pygments, use the following setting:

copybutton_exclude = '.linenos, .gp'

To skip all console outputs, add .go to the string above.

https://sphinx-copybutton.readthedocs.io/en/latest/use.html#keep-empty-lines

By default, sphinx-copybutton will also copy / pass through empty lines, determined by line.trim() === ''.

---

blank lines are retained with conf.py using >>> ?:

# copybutton_exclude = '.linenos, .gp, .go'
copybutton_prompt_text = r">>> ?|\.\.\. ?|\$ |In \[\d*\]: | {2,5}\.\.\.: | {5,8}: "
copybutton_prompt_is_regexp = True

gives:

a = 2
print(a)

b = 'wow'
print(b)

Also fails with ...:

>>> for i in (1,2):
...   print(i)
...
>>> # Loop finished
>>>
>>> # Blank line above
