When creating a Git alias that points to a function, sometimes Git provides the wrong tab completion by default (e.g. filename completion instead of branch name completion). This is how we can tell Git, which type of completion to use.
Programming
Check CORS Value from Command Line
I was checking a number of URL endpoints for CORS restrictions today and I wondered if I could check from the command line. Here are some example curl statement that get me the information I’m looking for. I think there is an opportunity for a custom function here but for now, these notes will do.
Display Keyboard Shortcut in WordPress Gutenberg
In Gutenberg (a.k.a. the WordPress Block Editor), keyboard shortcuts are displayed differently on Apple devices and other devices, e.g. ^H on an Apple device and Ctrl+H on other devices. This is accomplished with wp.keycodes.displayShortcut.
Using jq and nvm to set Node version
The nvm command allows you to switch between versions of node. Often a project will include a .nvmrc file to specify the version of node to use. Even if a project does not contain an .nvmrc file, you may be able to read the preferred node version from package.json and use that value with nvm.
ReactJS Component Limited Time Render HOC
I wanted to render a ReactJS component for a limited amount of time every time (think of a notification that pops up and then goes away). Ideally, we would like to be able to apply this limited time rendering to any component, so this was an excellent candidate for a Higher Order Component (HOC).
WordPress Filter Early Return Pattern
A common programming pattern when using WordPress filters is the early return pattern (also know as the “short-circuit” pattern). This pattern is useful when you want to allow a filter to override a value that is “expensive” to calculate.
zsh alias with fallback
In my zsh configuration I define a number of aliases. One particular zsh alias maps gl to my custom Git alias “git lg”. Since my zsh configuration is portable, I want to define a fallback if my custom Git alias does not exist on the machine.
Manually Trigger WordPress Heartbeat from Browser
When developing code related to the WordPress heartbeat, it is frustrating to make your code changes and then wait for the next heartbeat to occur. You can trigger the WordPress heartbeat in the browser manually to eliminate this delay.
What are PHP Namespaces?
When two functions (or classes) have the same name, it triggers a fatal error in PHP. Namespaces are used to avoid these naming collisions.
WordPress Hooks and PHP Namespaces
While PHP namespaces allow you to refer to a function in file without using the fully qualified name, there is a catch when adding a WordPress hook or filter. The PHP __NAMESPACE__ magic constant can be helpful in this situation.
