unhammer / wp-email-validate-check.php
Created March 17, 2020 08:57 — forked from yolabingo/wp-email-validate-check.php
Test Wordpress email validation regular expression
<?php
/*
When using a current PHP version, class-phpmailer.php:validateAddress() uses a complex regex ("pcre8") for email address validation.
PHP < 7.3 uses libpcre 8.x.
PHP 7.3 uses libpcre2 10.x.
Due to a bug in libpcre2 < 10.32-RC1 https://bugs.exim.org/show_bug.cgi?id=2300,
this email regex validation fails in PHP 7.3 with PCRE_VERSION < 10.32.

unhammer / vddiff
Last active December 14, 2019 16:57
little wrapper around `vd --diff` to get diff's -U option, since vd doesn't have a "go to next difference" feature ( https://github.com/saulpw/visidata/issues/303 )
#!/bin/bash
# Usage:
# $ vddiff -U4 before after -ftsv
# You can toggle between the before/after sheets with Ctrl-^
# If you keyboard layout makes that impossible to type, add an
# alternative binding to your ~/.visidatarc, e.g.
# bindkey("ø", "prev-sheet")

Right next to your address bar, make a "New bookmark" with this in, now you can easily remove all those header/footer bars that block your content
javascript:(function()%7B(function%20()%20%7Bvar%20i%2C%20elements%20%3D%20document.querySelectorAll('body%20*')%3Bfor%20(i%20%3D%200%3B%20i%20<%20elements.length%3B%20i%2B%2B)%20%7Bif%20(getComputedStyle(elements%5Bi%5D).position%20%3D%3D%3D%20'fixed')%20%7Belements%5Bi%5D.parentNode.removeChild(elements%5Bi%5D)%3B%7D%7D%7D)()%7D)()

unhammer / IDLE with asyncio + imaplib + mbsyncrc
Created September 12, 2019 07:43 — forked from boris-arzur/IDLE with asyncio + imaplib + mbsyncrc
I use a mail stack based on mbsync & notmuch. I want to run mbsync on new mails. IDLE allows watching efficiently one folder in my mailbox. Async makes is easy to watch a few connections.
#!python3
import imaplib
import os
import asyncio
loop = asyncio.get_event_loop()
conf = [x.strip().split() for x in open('mbsyncrc')]
