Plone: Reinstall Product Button

-
While creating Plone Products, I noticed that Plone will delete any created Portal objects, once a product associated with it has been uninstalled. Since I created a ZCatalog, which had data in it, I don't want that feature. After marching through the QuickInstaller code, I decided to add a "Reinstall Button" to all the respective products, to prevent uninstallation.

In your egg or product code root, simple add:
version.txt

Directory Structure Example (Python Pkg):
myproduct.stuff/myproduct/stuff/version.txt

The contents should be:
1.0-alpha build 1

When ever the version.txt is changed it will display the reinstall button.

Note: If you add the version.txt file to an existing product, you will have to manually uninstall the Product, then install it again. Otherwise, pressing "reinstall product" will anger the QuickInstaller (very bad).

The Fix for angry QuickInstaller:
If you manage to click "reinstall product" before you uninstall and install again, shame on you. To resolve, simply delete the QuickInstaller from the ZMI, then go to portal_setup, click the "Import" tab, select "QuickInstaller" from the list of profiles, then at the bottom, click "Import All Steps". This will cause all the installed products to go back to the "Products available for install" section, simply tick all the ones previously installed, and install them again.

Python SUDS with Windows Authentication (SOAP)

-
While intergrating Plone with CRM4, I stumbled upon Suds. However, it didn't support NTLM. Then I found python-ntlm, and merged the two libs. Below is the result. You can add it at the bottom of suds/transport.py class WindowsHttpAuthenticated(HttpAuthenticated): """ Provides Windows (NTLM) http authentication. @ivar pm: The password manager. @ivar handler: The authentication handler. @author: Christopher Bess """ def __init__(self, options): # try to import ntlm support try: from ntlm import HTTPNtlmAuthHandler except ImportError: raise Exception("Cannot import python-ntlm module") return HttpTransport.__init__(self, options) self.pm = u2.HTTPPasswordMgrWithDefaultRealm() self.handler = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(self.pm) self.urlopener = u2.build_opener(self.handler) u2.install_opener(self.urlopener)

Text Sherlock the OpenGrok alternative (Source Code Search Engine)

-
Image
OpenGrok has taken much to long to setup in the past, so in my dissatisfaction, I wrote Text Sherlock . Text Sherlock strives to be an easy to setup version of OpenGrok , written in Python. Think of Text Sherlock as a personal source code search engine. But, it can be run from a dedicated server. Features: It has built-in support for whoosh and xapian backends. It provides a web search interface similar to GitHub. It quickly installs. Set the configuration options in the local_settings.yml script. Then run an installation script in your install directory. Once done, everything is a simple command. Web search interface. Matched document interface. Well documented and it works as expected. Check it out and drop a comment or submit an issue via GitHub. https://github.com/cbess/text-sherlock

How to remove, update, or replace the WKWebView inputAccessoryView

-
Many others, including myself, have been trying to safely modify the WKWebView.inputAccessoryView. Now in iOS 13+, you can do it! TL;DR; The WebKit team update the code, Apple updated their dependency in iOS 13. Swift code sample: import WebKit class RichEditorWebView: WKWebView { var accessoryView: UIView? override var inputAccessoryView: UIView? { // remove/replace the default accessory view return accessoryView } } In another class somewhere: // set accessory view to replace it, if left untouched, then it will be removed let webView = RichEditorWebView() webView.accessoryView = SomeAwesomeInputAccessoryView() Because WebKit is a library that iOS uses (like SQLite), I assumed that Apple would update that dependency as well for iOS 13, since the change was resolved around June 2019.
