[ANN] Amber now includes a REPL (cool!)

Hi guys,

I just pushed a simple REPL written top of node.js.
You can run it with:

./bin/amber

The REPL is written in Amber, you can browse the code at repl/REPL.st

Cheers,
Nico

Re: [ANN] Amber now includes a REPL (cool!)

Good,

Amber will become a "regular" scripting language in addition to
"living" on the browser and having a command line compiler from amber
to Javascript!!

I did a amber.bat file (modeled) after server.bat for MSWindows

amber.bat contains

@cd "%~dp0\.."
@node ./repl/repl.js

then if I start I get
amber>>

What do I do next?

help

gives
nil

how do I get out again

exit
quit
end
do not work (adding a dot does not help).
and adding a self in front of it neither.

A little bit of documentation is needed ......

Evaluate regular Smalltalk code, line by line.

amber >> 1+1
2
amber >> Object new
a Object
amber >>

To exit, ctrl+c (or ctrl+d)

Re: [ANN] Amber now includes a REPL (cool!)

The code is actually pretty short!

https://github.com/NicolasPetton/amber/blob/master/repl/REPL.st

Another question:

What is the 'require' object in the the 'initialize' method?

-- HH

Object subclass: #Repl
instanceVariableNames: 'readline interface util'
category: 'REPL'!

!Repl methodsFor: 'accessing'!

prompt
^'amber >> '
! !

!Repl methodsFor: 'actions'!

createInterface
"No completion for now"
interface := readline createInterface: process stdin stdout: process stdout.
interface on: 'line' do: [:buffer | self eval: buffer].
interface on: 'close' do: [self close].
self setPrompt.
interface prompt
!

setPrompt
interface setPrompt: self prompt
!

close
process stdin destroy
!

eval: buffer
| result |
buffer isEmpty ifFalse: [
result := Compiler new loadExpression: buffer.
Transcript show: result].
self setPrompt.
interface prompt
! !

!Repl methodsFor: 'initialization'!

initialize
super initialize.
readline := require value: 'readline'.
util := require value: 'util'
! !

!Repl class methodsFor: 'not yet classified'!

main
self new createInterface
! !

Re: [ANN] Amber now includes a REPL (cool!)

In reply to this post by Hannes Hirzel

I wrote several nodejs examples all the way back at ESUG in fact. amberc in itself runs on node. So if you look at the examples directory you find several node examples. The REPL does not really give you anything new - except for playing/experimenting of course. But the workspace is better IMHO.

Re: [ANN] Amber now includes a REPL (cool!)

Thank you Göran

I found the examples. They are under examples\nodejs.

In particular I like TrivialServer.st.

I did not see an example for reading a text file and processing it.
When I browse through the classes I do not see a class for doing file
I/O. I think file I/O is something needed to have a complete REPL
experience.

nodejs has a File class

http://nodejs.org/docs/v0.0.1/api.html#file_file

with an example of

var file = new node.fs.File();
file.open("/tmp/blah", "w+");
file.write("hello");
file.write("world");
file.close();

How would this be written in Amber?

Thank you for the answer in advance

The API has evolved since 0.0.1 :)
http://nodejs.org/docs/v0.4.12/api/fs.html

There's an example in the server/ directory. FileServer.st handles GET
requests (answers the contents of files) and PUT requests (write to
files).

https://github.com/NicolasPetton/amber/blob/master/server/FileServer.st#L66

Nico

Re: [ANN] Amber now includes a REPL (cool!)

Nico,

thank you for the link to nodejs 0.4.12 :-)

The FileServer.st program is an example, right? It is not used by the
"regular" server?

Learning from FileServer.st (initialize method)

I did

fs := self require: 'fs'.

It was not successful.

Tjhen I did

obj := Object new.
obj require: 'fs'.

Both times it said that it does not understand #require:

Then I went for
<var fs = require('fs');>

Am I missing something here or are there parts which are not yet implemented?

I want to read and write a text file in the REPL.

require is a function. Call it as if it was a block:

fs = require value: 'os'

Funky, right? :)

Re: [ANN] Amber now includes a REPL (cool!)

Nico and Goran,

Good,

the bat script called 'amber.bat' I did is now

@cd "%~dp0\.."
@node ./repl/amber.js

It is in the 'bin' directory. I did it the way Goran did 'server.bat'.
I do not actually understand what the first line means.

The following example now works fine

amber >> fs := require value: 'fs'.
amber >> fs readFile: 'README.md' do: [:ex :file | console log: file
printString].

I found out about the fs method #readFile:do from the FileServer.st
example (is in server directory) as you had suggested.

A complete write example session

S:\Project\amber\NicolasPetton-amber-0.9-129>bin\amber
amber >> fs := require value: 'fs'.
[object Object]
amber >> stream := fs createWriteStream: 'hello.txt'.
[object Object]
amber >> stream write: 'hello'.
false
amber >> stream write: 'world!'.
false
amber >> stream end.
nil
amber >>

Where can I find out which other file system methods are defined (i.e.
wrapped with Smalltalk methods)?

Have a nice day
Hannes

BTW: repl.st is still in the repl directory. Is it still used as I now
directly call amber.js in the batch script?

Re: [ANN] Amber now includes a REPL (cool!)

In reply to this post by Nicolas Petton

Regarding "other methods that are wrappaed" - here is the beauty: Nothing is wrapped!

This means you can use *everything*, and this is a killer feature of Amber. Same goes for example for jQuery - all works. Even if you throw in a new version or a completely different lib. Full js interoperability.

Otherwise Amber would have been in an impossible situation vs js IMHO.

First line is win-magic crap to change directory to the parent directory of the running bat file.
