[BUG] inline_styles has no effect when exporting to SVG?

[pawamoy]

Describe the bug I'm adding an example using PyTermGUI to my Markdown Exec's gallery. Here's my code:

from io import StringIO
import pytermgui as ptg

code = """
while True:
    if condition:
        print("Hello")
    else:
        print("Goodbye")

    input()
"""

with ptg.Terminal(stream=StringIO(), size=(20, 20)).record() as recorder:
    recorder.write(ptg.tim.parse(ptg.highlight_python(code)))
    print(recorder.export_svg(inline_styles=True))

Whatever the value of inline_styles, I get a style tag in the final HTML. This is problematic because it affects other parts of the page.

Expected behavior No global style set in the page.

System information

PyTermGUI version 6.2.1

System details:
    Python version: 3.8.13
    $TERM:          xterm-256color
    $COLORTERM:     truecolor
    Color support:  ColorSystem.TRUE
    OS Platform:    Linux-5.17.9-arch1-1-x86_64-with-glibc2.35

Possible cause I might misunderstand the purpose of the mentioned style tag or the inline_styles option.

Possible solution Use more specific CSS selectors to affect only PyTermGUI's own SVG.

Yup, what that argument does is push all the per-text styling to inline. I will add some ptg tag to the text elements.

Actually, does it effect other parts of the website? I was under the impression that styles defined within an SVG file are scoped to it, but I might be completely misunderstanding the system.

Yes it does affect other parts of the page, at least another SVG aobve it in the page :slightly_smiling_face:

Without PyTermGUI's SVG style:

With:

Should be good now! By default SVG text items will use the class ptg, but that can be change with the prefix argument to the exporter.

Thanks a lot! Should I wait for a release or do you want me to try master branch?

The release should be out in a couple of hours, but I'm not expecting any major changes. A quick test would be much appreciated!
