RFC Test Selectors

Owner: Brian Vaughn

As of facebook/react/pull/22760, the experimental Test Selector API is now available in the experimental release channel.

To test the API, first install the experimental release:

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

ffmpeg - GIF timelapse with timestamp clock

First frame of our input movie:

Add timestamp clock to video

ffmpeg -i input.mov -vf "drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf:expansion=normal: text='%{pts \\: hms}': fontcolor=white:fontsize=48: x=(w-text_w)/2: y=h-th-10: box=1: boxcolor=black: boxborderw=5: line_spacing=32" -vcodec libx264 -vb 2600k -strict -2 -preset slower -f mp4 -an timestamp_clock.mp4

In the first step we take our input movie input.mov and add at bottom center a black box with white timestamp
