[HTML]: autocomplete datalist example

Form data fetch post example

const formData = new FormData();
const fileField = document.querySelector('input[type="file"]');

formData.append('username', 'abc123');
formData.append('avatar', fileField.files[0]);

try {
  const response = await fetch('https://example.com/profile/avatar', {
    method: 'PUT',
    body: formData
  });

  console.log('Успех:', JSON.stringify(result));
} catch (error) {
  console.error('Ошибка:', error);

Missing favicon.ico

Filename: /favicon.ico
Status: 404 Not Found

We should redirect not found pages to search pages automatically

Example: https://onelinerhub.com/apache

Might need new syntax highlighter

Current (highlight.js) is very poor on some languages, example:
https://onelinerhub.com/mysql/concatenate_rows

Alternative tech -> replace with alternative ways (?)

Here:
https://onelinerhub.com/python/if_else

Improve search usability

Currently it's too hard to:

altering search
search from other than main pages

[supervisor] / export display

[program:test]
command=export DISPLAY=:0 && python test.py
user=root
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/test.log
loglevel=info

Teach explanation blocks to understand positions

Have ability to specify same substrings, but mind the order (1st, 2nd, ...):
https://onelinerhub.com/c/swap_two_variables_values

In chart.js code pieces it's more convenient to copy just a part of configuration options by default, instead of whole code example. Think of creating new markup way to highlight default copying area in such cases.

JS / before unload confirmation

window.onbeforeunload = function(e) {
  var dialogText = 'Dialog text here';
  e.returnValue = dialogText;
  return dialogText;
};

$csv_line = stream_get_contents($f);
return rtrim($csv_line);
}

Can't scroll past first page

Using Firefox (actually Waterfox Classic), looking at Python one-liners -- can only view first page. No way to scroll further, either with cursor or arrow keys.
