Appearance

Getting Started ​

Four steps, done once. Then you're ready to use it.

1. Install Julia (1.12 or newer) ​

  • macOS / Linux: curl -fsSL https://install.julialang.org | sh

  • Windows: winget install --name Julia --id 9NJNWW8PVKMN -e -s msstore

Open a new terminal and check: julia --version.

2. Download Timekeepers.jl ​

bash
git clone https://github.com/JuliaGeophysics/Timekeepers.jl

No git? On https://github.com/JuliaGeophysics/Timekeepers.jl click Code → Download ZIP and unzip it.

3. Install its packages ​

bash
cd Timekeepers.jl
julia --project=. -t auto

At the julia> prompt, type ], then instantiate, then press Backspace when it finishes:

julia
(Timekeepers) pkg> instantiate

The first time takes several minutes (about 290 packages, mostly graphics).

4. Check that windows open ​

The windows need a desktop with OpenGL 3.3 or newer. Check with:

julia
using GLMakie
display(scatter(1:10))

A window with ten dots means you're ready.

Already have a Julia project?

Skip steps 2 and 3. In your project, type ] and run add https://github.com/JuliaGeophysics/Timekeepers.jl.

Use ​

Start Julia in the Timekeepers.jl folder with julia --project=. -t auto, then:

julia
using Timekeepers

run_tkdash("data/survey")          # 1. see which sites recorded together
run_tkapp("data/LEMI090.txt")      # 2. mask bad intervals, write clean data
run_tkproc("data/survey")          # 3. estimate transfer functions, write EDI files

Use your own paths. Each window stays open until you close it.
