hash-files.py

Standalone script that mimics [GitHub Actions' hashFiles helper][hashFiles docs] ([used by actions/setup-python][PipCache], and frequently with [actions/cache])

Upstream hashFiles source is [here][hashFiles source], this script was written while debugging [setup-python#919].

Examples

git clone https://gist.github.com/ryan-williams/2e616363c68072bf67cad675fcb18f3b hashfiles-gist
export PATH=$PATH:$(pwd)/hashfiles-gist

watchman basic example

I found the watchman docs hard to follow / bereft of useful examples. Below is my attempt at a quickstart guide; see ryan-williams/watchman-helpers for some aliases and other scripts.

• 0. Install watchman
• 1. Configure a "watch" on the current directory
  • 1b. List currently watched directories
  • 1c. Remove a watched directory
• 2. Set up a "trigger": continuously run a command in response to changes
  • 2a. rsync a directory to a remote host
• Is there a simpler way to trigger on all files?

I hit some issues installing a Nitto BM-5R rack (1, 2) on my Brompton Electric:

Having fastened 3 of the 4 rack/stay mount points (as well as 2 stay-frame points and the rack/fender/frame and rack/fender points), the 4th rack/stay mount is misaligned beyond my ability to force it into place.

I'm not sure if I've installed it incorrectly, or what. The light cable is also ≈½" too short to reach the light-mount points on the back of the rack.

Here are some close-ups:
