Add more samples

[ForNeVeR]

Current samples are not presentable enough. To show Morganey to guys, I want examples of "Hello world" and more simple examples with annotated output.

[rexim]

@ForNeVeR I'm sorry, but what do you mean by "annotated output"?

[rexim]

@ForNeVeR I've planned this for next Morning Tsoding. I'd really appreciate if you created a list of exact samples you need and it posted here. Later I'll implement this list right on the stream. Thanks!

[ForNeVeR]

@rexim by "annotated output" I mean that you should write command output in comments. For example, (in python) that would be

print (2 + 2) # => 4

[ForNeVeR]

...and I'll try to create the example list tonight.

So, okay, let's think about it.

1. Add a "Hello world" program. (Seriously, we haven't one.)

2. Add an arithmetic example. E.g. define and explain a multiply function (yeah, I know that the standard library have one), print a result of 2*8.

3. Add an interactive example. echo program: read line and print it back.

4. List functions example. ohce program: read line and print it back​_wards_.

5. Add a complex interactive example. Read two numbers from stdin and print their sum. Read a list of numbers from stdin (is it possible? Could Morganey program detect EOF? If no, then the length of the list should be the first parameter read), print their product.

6. ⚠ Fun. Write a program that reads an optional name parameter from stdin and prints a message:

   <h1>Hello {name}</h1>
   Enter next name: <form><input name="name" /><button>Hi</button></form>
   

   Add an instruction to connect that to CGI. Why the hell not! I recommend to put additional parser in front of program that will parse and strip out HTTP headers and stuff.

@rexim, please feel free to split this task to multiple if you think that some of my ideas are too complex or you simply don't like them.

@ForNeVeR thanks for the specs! I'll do mah best!

is it possible? Could Morganey program detect EOF? If no, then the length of the list should be the first parameter read

Yeah, it can. The input binding simply ends on EOF. We probably need to document it in https://github.com/morganey-lang/Morganey/wiki/Execution-Mode-Semantic#input-stream
