meta Meta language released

[Kaj de Vos]

not-count: 10

repeat 10 [write/line not-count: 10 - not-count]

This is an 8-bit loop.

[zbyti]

I understand, but this behavior is inconsistent for me.

 

For this I need to remember the type/value I put in for repeat to know how this gonna be behave.

[Kaj de Vos]

No, it just counts the number of times you tell it. It's exactly the same as in Logo, which was carefully designed sixty years ago to teach kids programming.

 

You think it should be more complicated because you are used to that.

[zbyti]

What tempted me to call it counter - now we can't get along  

[zbyti]

dupa: 10

repeat 10 [write/line dupa: 10 - dupa]

write/line "dupa end"

[Kaj de Vos]

Use

for counter 10 []

instead.

[zbyti]

ok... I made a fool of myself, correcting the code accidentally deleted the variable and I did not notice it - hence further unnecessary discussion.

 

1000 - var behave exactly the same as 10 - var.

 

apologize.

To clarify, I was sure the code looks like this:

 

count: 1000

repeat count [write/line count: 1000 - count]

write/line "dupa end"

but it looked like this:

 

count: 1000

repeat count [write/line 1000 - count]

write/line "dupa end"

the first produces 0 and 1000 alternately (which I don't understand), and the second of course 0.

 

lack of readability from my side

Ah. ? No problem.

[zbyti]

ping atari8.metaproject.frl
ping: atari8.metaproject.frl: Temporary failure in name resolution

this makes it difficult to play with. I wanted to write something more in Meta.

[zbyti]

unsafe!!! constant reference volatile byte! [
  RND= ~D20A
]

forever [
  either RND < ~80 [write "/"] [write "\\"]
]

write "workaround"

program.xex

 

without last line I have an error:

 

out.c:26: Error: Expression expected
out.c:26: Error: Illegal function call
out.c:31: Error: Incomplete type 'void'
out.c:31: Error: Incomplete type 'void'

switch, and, or, xor - not implemented yet?

 

and again:

 

./compile test.meta 
Compiling file test.meta

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

Result is in file program.xex

it's not fun...

XOR is X-OR, no SWITCH yet

Looks like you need a better DNS provider. Try 1.1.1.1 or Google.

I don't think so. I used 8.8.8.8 and 1.1.1.1.

 

@Kaj de Vos I'll back to testing Meta if you clearly let us know what part of REBOL is implemented. For now I used http://rigaux.org/language-study/syntax-across-languages-per-language/Rebol.html

 

It's time consuming - guessing whats works what not. Online compiler spoil fun too.

[Kaj de Vos]

I have a solution in the works for conversion from REBOL.

 

You definitely have unreliable DNS. It's not my server doing that.

    if STICK0 = 13 [write/line "DOWN"]
    if STICK0 = 7 [write/line "RIGHT"]
    if STICK0 = 11 [write/line "LEFT"]

write "workaround"

 

program.xex

 

without not implemented switch + workaround

 

[Kaj de Vos]

Nested EITHER is better.

simply I just deleted "switch" and added "if" to the rest - even indentations remained  

[zbyti]

foo: byte![1 2 3]

write "..."

?

[Kaj de Vos]

This is unimplemented behaviour. The syntax for literal arrays is different. I'll look it up tomorrow. I'm on my phone now.

[zbyti]

Sure.

 

Take your time and make proper documentation, implement missing things and improve parser.

 

In current state I can't image who else wants to take a ride withe Meta  I'm quit now too.

 

 

[Kaj de Vos]

I have someone else using it right now.

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

Result is in file program.xex

d:\Projekty\Meta>dir /b program.xex

I tried to use the compile.ape with curl.exe to compile a sample program, however with "Result is in file program.xex" there is no program.xex in the current directory. Any hints?

Again, there isn't one yet. It takes a lot of time to write documentation. It's great if you want to try Meta already, but then you have to make do with the few examples I have published so far and the REBOL documentation I have selected. It's really useful to work through that to learn the basics.

I agree that writing documentation is time consuming, but documentation for a new language is a must have. Maybe less time consuming would be pointing the differences from REBOL? Now for the ones that try to use the language it is a guessing game.

Here is the best REBOL guide that I found so far:
