Starting a new Julia environment is very ease

(test) pkg>
Is there a way to visualize a list of all the environments?

I recently found a file ~/.julia/logs/manifest_usage.toml which lists all recently used environments. I understand that this file is also used for ] gc.

Being able to list them all would be a nice feature. Basically, just parse that file, sort the keys and print them. Would be a nice addition to Pkg.

I arrived here looking for a way to list environments =)

Looks like there is no env by default for the binary

my workaround:
function list_Pkg_environments()
env_dir = joinpath(Pkg.envdir(), string("v", VERSION)[1:end-2])
# env_dir = Pkg.envdir()
dir_list = readdir(env_dir, join= false)
dir_list_full = readdir(env_dir, join= true)
env_list = []
for i_ = eachindex(dir_list)
if isdir(dir_list_full[i_])
println(dir_list[i_])
push!(env_list, dir_list[i_])
end
end
return env_list
end

here is my function to select and activate a user defined Julia-environment:
function select_Pkg_environment(_environment::String="")
curr_dir = pwd()
env_dir = joinpath(Pkg.envdir(), string("v", VERSION)[1:end-2])
# env_dir = Pkg.envdir()
dir_list = readdir(env_dir, join= false)
dir_list_full = readdir(env_dir, join= true)
env_list = []
for i_ = eachindex(dir_list)
if isdir(dir_list_full[i_])
# println(dir_list[i_])
push!(env_list, dir_list[i_])
end
end
if isempty(_environment)
if isempty(env_list)
println("No additional environments found!")
else
println("---- Number of available environments: ", length(env_list), " ----")
for i_ = eachindex(env_list)
println(i_, ".) ",env_list[i_])
end
println("------------------------------------------------")
end
else
if any(occursin.(_environment, string.(env_list)))
if splitpath(Base.active_project())[end-1] != _environment
cd(env_dir)
Pkg.activate(_environment)
cd(curr_dir)
println("current dir: ", pwd())
else
@info(string("Environment \"", _environment, "\" is already loaded!"))
end
else
@warn(string("Julia Pkg-environment: \"", _environment, "\" not found!"))
@info("Call function without argument to list available environments.")
end
end
return env_list
end
The strange thing is, that the command:
Pkg.activate("MyEnvironment")
opens a new user defined environment, if it is not yet known in a subfolder of Pkg.envdir().
And establishes the two environment files Project.toml & Manifest.toml in a sub-directory
with the name of the user defined environment as soon as a package is added via: Pkg.add("PackageName").
But the next time I give the identical command: Pkg.activate("MyEnvironment")
Pkg wants to establish a new environment definition directory at the current directory pwd().
Is this a bug or a feature?

And here my code to establish a new environment in a sub-folder of Pkg.envdir():
function MyLib_Add_Pkg_env(_environment::String="")
curr_dir = pwd()
env_dir = joinpath(Pkg.envdir(), string("v", VERSION)[1:end-2])
# env_dir = Pkg.envdir()
dir_list = readdir(env_dir, join= false)
dir_list_full = readdir(env_dir, join= true)
env_list = []
for i_ = eachindex(dir_list)
if isdir(dir_list_full[i_])
# println(dir_list[i_])
push!(env_list, dir_list[i_])
end
end
if isempty(_environment) || ~any(occursin.(_environment, string.(env_list)))
cd(env_dir)
Pkg.activate(_environment)
Pkg.add("Revise")
cd(curr_dir)
println("current dir: ", pwd())
end
return env_list
end
I have updated / debugged my two functions:
function MyLib_add_primary_env(_environment::String="")
Pkg.activate() # make sure we are in the primary default environment
env_dir, _ = splitdir(Base.active_project())
# env_dir = Pkg.envdir()
dir_list = readdir(env_dir, join= false)
dir_list_full = readdir(env_dir, join= true)
env_list = []
for i_ = eachindex(dir_list)
if isdir(dir_list_full[i_])
# println(dir_list[i_])
push!(env_list, dir_list[i_])
end
end
if isempty(_environment) || ~any(occursin.(_environment, string.(env_list)))
prim_env_dir = joinpath(env_dir, _environment)
Pkg.activate(prim_env_dir)
Pkg.instantiate()
end
return env_list
end
and:
function MyLib_select_primary_env(_environment::String="")
b_dbg = false
prim_env_dir = []
if VERSION < VersionNumber(1, 6, 7)
error("Julia too old! Please upgrade to v > v1.6.7!")
else
Pkg.activate() # make sure we are in the primary default environment
env_dir, _ = splitdir(Base.active_project())
end
# env_dir = Pkg.envdir()
dir_list = readdir(env_dir, join= false)
dir_list_full = readdir(env_dir, join= true)
env_list = []
for i_ = eachindex(dir_list)
if isdir(dir_list_full[i_])
# println(dir_list[i_])
push!(env_list, dir_list[i_])
end
end
if isempty(_environment)
Pkg.activate()
if isempty(env_list)
println("No additional environments found!")
else
if b_dbg
println("---- Number of available environments: ", length(env_list), " ----")
for i_ = eachindex(env_list)
println(i_, ".) ",env_list[i_])
end
println("------------------------------------------------")
end
end
else
prim_env_dir = joinpath(env_dir, _environment)
if any(occursin.(_environment, string.(env_list)))
if splitpath(Base.active_project())[end-1] != _environment
Pkg.activate(prim_env_dir)
else
@info(string("Environment \"", _environment, "\" is already loaded!"))
end
else
@warn(string("Julia Pkg-environment: \"", _environment, "\" not found!"))
