Configure iTerm2's Smart Selection for Diff Paths

Published under Mango Snippets, Jul 30, 2026

When working with diffs in the terminal, for example:

--- a/src/pyrefdev/mapping/pylabel.py
+++ b/src/pyrefdev/mapping/pylabel.py

I often need to copy the path of the file. But double-clicking the path selects a/src/pyrefdev/mapping/pylabel.py by default.

Luckily, you can configure iTerm2's Smart Selection with this regex to only select the path part:

(?<=[-+]{3} [ab]/)\S+

Here is a step-by-step guide:

• Go to Settings > Profiles > Advanced > Smart Selection > Edit.
• Click the + button.
• Set Regular expression to (?<=[-+]{3} [ab]/)\S+.
• Set the precision to Very High so it wins over the built-in path rules.

Now a double-click selects just src/pyrefdev/mapping/pylabel.py.

my pet peeve: when parent URLs don't work

for example if your website has a page:

• site.domain/path/to/this/page

these pages should always be valid too:

• site.domain/path/to/this
• site.domain/path/to
• site.domain/path

Mango Exposure v2026.2

Published under Mango Exposure, Jul 30, 2026

Mango Exposure v2026.2 is now available. This one is mostly about sensors.

NEW:

• A Release Notes screen in Settings, so the app can tell you what changed without you coming here.
• The 1 inch sensor, used by cameras like the Sony RX100 series and most drones.
• The 44x33 digital medium format sensor, used by the Fujifilm GFX and Hasselblad X series.
• The 53x40 digital medium format sensor, used by the Phase One IQ4 and Hasselblad H series.

CHANGED:

• The Four Thirds sensor is now labelled Four Thirds / Micro Four Thirds.
• The APS-C Sony/Nikon/Pentax sensor now mentions Fujifilm, which uses the same sensor size.

Happy photographing, whatever you shoot with ^_^

Mango Exposure v2026.1

Published under Mango Exposure, Jan 24, 2026

After 4 months of deliberation, I have decided to adopt Liquid Glass in Mango Exposure v2026.1. Why? Because Apple told me to.

Anyway, happy photographing no matter where you are ^_^

Somehow my fastlane upload pipeline stopped working, due to shadowing the system rsync binary.

I would have never guessed this root cause.

Historically it would take me hours of debugging and head banging, but Opus 4.5 just did it under one minute by itself.

Found it! You have a Homebrew rsync (3.4.1) that's being used instead of Apple's built-in openrsync:

• which rsync → /Users/mango/tools/brew/bin/rsync (Homebrew 3.4.1)
• /usr/bin/rsync → Apple's openrsync (protocol 29)

Xcode's export process is mixing these two incompatible versions, causing the "syntax or usage error" when they try to communicate.
