Qute Code Hint

A small qutebrowser userscript for copying code snippets on web pages to the clipboard.

Example

Hinting:

Copying to clipboard:

Installation

Download the script:

wget https://raw.githubusercontent.com/LaurenceWarne/qute-code-hint/master/code_select.py -O ~/.local/share/qutebrowser/userscripts/code_select.py

In your qutebrowser config file create a new custom group for code:

c.hints.selectors["code"] = [
    # Selects all code tags whose direct parent is not a pre tag
    ":not(pre) > code",
    "pre"
]

Bind the userscript using a keybinding of your choice:

...
'<ctrl-#>': 'hint code userscript code_select.py',
...

Optionally install the python pyperclip module for better multiline copying:

pip3 install pyperclip --user
# Alternatively for PEP 668 compliance, you can install from your package manager, e.g.
sudo apt install python3-pyperclip

If you're having issues with pyperclip, you can use pyclip instead:

pip3 install pyclip

Multiline Copying

Without pyperclip/pyclip the default behaviour for code snippets spanning multiple lines is to join them all on one line, with semicolons separating the previously seperate lines.

qute-code-hint's Issues

Pyperclip possibly no longer needed

Not sure if this is true across different version of Qutebrowser, but I was able to copy multiline code blocks without Pyperclip simply by commenting out the line:

        code_text = re.sub("(\n)+", delimiter, code_text)

Can't copy certain code from sites

I wasn't able to copy certain codeblocks from sites like:
https://www.npmjs.com/package/qutejs
https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-list/

Apparently it was ElementTree parser problem

After adding this to script, I can now copy

def parse_text_content(element):
    magic = '''<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
                "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" [
                <!ENTITY nbsp ' '>
                ]>'''  # You can define more entities here, if needed
    root = ET.fromstring(magic + element)
    text = ET.tostring(root, encoding="unicode", method="text")
    text = html.unescape(text)
    return text
