kurtbuilds / alfwin

Installation

Run this command:

just install

After that, manually go to System Preferences -> Security & Privacy -> Privacy. Add the Screen Recording permission to any .app that will run the alfwin binary. In general, this will be Alfred 4 and iTerm2 when in development.

That setting should cause the program to return valid results for window names.

Strategy

1. Two possible strategies
   1. Have a daemon running that writes AppleScripts to filesystem.

Benchmarking

 11:46:57 kurt@kurts-MacBook-Pro:~/work/alfwin $ t build bench
osacompile -l JavaScript -o winnames.jxa.scpt winnames.jxa.applescript
osacompile  -o winnames.scpt winnames.applescript
hyperfine --warmup 3 "osascript winnames.jxa.scpt" "osascript winnames.scpt" "osascript winnames.applescript" "osascript -l JavaScript winnames.jxa.applescript"
Benchmark 1: osascript winnames.jxa.scpt
  Time (mean ± σ):      2.012 s ±  0.091 s    [User: 0.079 s, System: 0.031 s]
  Range (min … max):    1.945 s …  2.196 s    10 runs

  Warning: The first benchmarking run for this command was significantly slower than the rest (2.051 s). This could be caused by (filesystem) caches that were not filled until after the first run. You should consider using the '--warmup' option to fill those caches before the actual benchmark. Alternatively, use the '--prepare' option to clear the caches before each timing run.

Benchmark 2: osascript winnames.scpt
  Time (mean ± σ):     327.2 ms ±  39.0 ms    [User: 29.3 ms, System: 28.3 ms]
  Range (min … max):   296.3 ms … 391.8 ms    10 runs

Benchmark 3: osascript winnames.applescript
  Time (mean ± σ):     386.1 ms ±  17.8 ms    [User: 46.9 ms, System: 36.2 ms]
  Range (min … max):   352.7 ms … 402.1 ms    10 runs

Benchmark 4: osascript -l JavaScript winnames.jxa.applescript
  Time (mean ± σ):      1.952 s ±  0.016 s    [User: 0.079 s, System: 0.030 s]
  Range (min … max):    1.945 s …  1.997 s    10 runs

  Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet PC without any interferences from other programs. It might help to use the '--warmup' or '--prepare' OPTIONS.
