No this doesn't work either, unless you sacrifice the functionality of using variables as commands. Suppose $echo is equal to "echo", what is the most reasonable thing one would expect `$echo = $ip` to do? Also consider the f

Of course! PowerShell definitely has a lot of brilliant ideas. Sadly it is overenginnered and has quite some design mistakes. Nevertheless it has served as a great source of inspiration for me - I have actually gone through several PowerS

The need for `set` has to do with syntax. In shells the first word of a statement is always considered to be the command, so "x = 5" will not work - it reads "execute command 'x' with arguments '=' and &#x

A shell is a REPL. The problem is that the shell is sloppy in that it only deals with bytes and cannot process any complex data structure. Again, advertisement for my side project https://github.com/elves/elvish , a Uni

Option hell is indeed a problem. The problem with `find` happens to have a solution (-print0). However it is a PITA in deal with \0-separated strings in traditional shells, unless you pipe it to another command that happens to recognize \0-

Yes, one thing that can be done (in future) with elvish is writing wrappers for external commands that run the commands and convert their (bytes) output to strongly typed values. For instance, `ls` outputs a bunch of lines where each line i

var is for declaration, set for assignment. This is an important contrast that some dynamic languages miss; ironically JavaScript got it right. Contrast this var $x = "foo"; if $true { set $x = "bar" }; echo $x # o

Time for advertisement! You might like elvish https://github.com/elves/elvish which proudly has optional typing and much more well-defined semantics than say, bash. This is work in progress though. Advertisement aside,

Best wishes on the switch, but I'm afraid that the leap being taken is too big. Suddenly we go from bare HTML served by cgi to a single-page, style-rich and interaction-rich JavaScript application. That said, I actually like the new we

IIRC the new VM (MoarVM) is around for quite a short time and it replaced Parrot in a dramatically short time. What are the advantages of MoarVM over Parrot and why were we stuck at Parrot for so long before giving it up?

I just played the nice little game on about:home. But shooting is extremely tricky since I need to keep suppressing my hjkl muscle memory. Update: that game seems to be a demo of Voxatron in the bundle.

Yes it's very poor, but we're talking about education here. Primary and secondary education is free except for a yearly contribution that is typically 100 to 200 Yuan (16 to 32 dollars), which even the poorest family can afford. I

I think go's approach to readability is comparable to "simple English". Both have a minimal set of words (tokens) and syntax constructs. You lose some witty constructs, and you often find yourself writing in a stupid way. But

Codes are read much more often than written. paredit makes editing parens easier, but reading them is still difficult for the unskilled (rainbow parens help, but it's still far from painless). Compare this to how autocompletion makes i

Maybe some lisp hackers gradually find out that a lot of parenthesis is not that fun for everyone. Not meant to enrage Lisp hackers, I actually find parenthesis bearable. There is also Pyret( http://www.pyret.org/ ) created b

Ah, indeed. It turns out that the "doc" actually means "text documents" instead of "software documentation".

Well, it runs on the terminal. But not on the command line. These are different concepts.

The first few parts make a pretty good pipeline preach. Two interesting points about pipelines are the concurrency and the difficulty to handle errors (at least without cluttering the syntax), which are often missed by newcomers.

Good to know that, thanks. I have captured and pushed the screenshots with subpixel turned off.
