Re: [julia-users] ls()?

2016-09-14 Thread Tony Kelman 
Julia supports Windows, which is not a posix platform. So while Julia uses 
posix-inspired names in some places, that's not universally the case, and 
they're often jargony and confusing if you're not a Unix user.

Which can get gnarly on Windows, depending how you launched Julia. E.g. 
just launching from the Julia executable:


shell> ls
ERROR: could not spawn `ls`: no such file or directory (ENOENT)
 in _jl_spawn(::String, ::Array{String,1}, ::Ptr{Void}, ::Base.Process, 
::RawFD, ::RawFD, ::RawFD) at .\process.jl:321

There's already shell mode:

;cd projects
;ls


in the REPL.

No, but you've implemented functions with POSIX names

> yes, ls() could be a better name

In the REPL, I might

julia> cd("projects")

And want to 

julia> ls()

to see what's there

But, I probably wouldn't want to do that in Julia file

rd = readdir(pwd())  # ls() doesn't make sense here

So, maybe alias them?

There are POSIX standards for new programming language function names? But
yes, ls() could be a better name.

I thought it might be an idea to stick with POSIX standards.

You can find a thread/issue where this is discussed. Some group decided to 
call it readdir() and like it more. I just got used to it. I think it's 
silly, but it's just syntax.

In the filesystem package, if we have pwd() and cd(), why do we not have 
ls()?
