I’m looking at this project called ComputationalHomology.jl, and learning some Julia along the way. I notice that at line 122 of file constructions.jl
there is this line:
splxs = map(Simplex, 1:n)
Which if I just (after using ComputationalHomology
) run in the REPL (say with n = 10
) spits out
"σ(1,)"
"σ(2,)"
"σ(3,)"
"σ(4,)"
"σ(5,)"
"σ(6,)"
"σ(7,)"
"σ(8,)"
"σ(9,)"
"σ(10,)"
What cues me about this is the σ
, and I went to look for where this comes from in the project. As far as I can tell, the relevant part of the code in the ComputationalHomology project is the following line 14 from simplex.jl
(ie the “source file” for the above Simplex object):
show(io::IO, splx::Simplex) = show(io, "σ$(splx.vs)")
I’m wondering then if there is something I’m missing, or if the show
function is what is default run when you run a function in the REPL.
Sorry if my syntax/jargon is not quite right, am quite new to this language, and looking to become more familiar!
