as mentioned here.
I am getting an error as “UndefVarError: ? not defined”
Where did you try this? Can you copy-paste your input and output? This is what I get in the Julia REPL:
help?> println search: println printstyled print_with_color print print_shortest sprint isprint println([io::IO], xs...) Print (using print) xs followed by a newline. If io is not supplied, prints to stdout. Examples ≡≡≡≡≡≡≡≡≡≡ julia> println("Hello, world") Hello, world julia> io = IOBuffer(); julia> println(io, "Hello, world") julia> String(take!(io)) "Hello, world\n"
Hi, thanks for the reply. I had tried it on IJulia
UndefVarError: ? not defined
That should work in the Jupyter notebook. Can you provide a screenshot?
Ah, yeah, I can reproduce that. Removing the first line (the
#To get docs comment) fixes the issue. To use the help lookup, the
? character needs to be the very first thing in the cell.
You can get the same problem at the REPL:
julia> # This is a comment ?println ERROR: UndefVarError: ? not defined
(note that I had to press alt-enter after the comment line to get a new line without executing anything)
