Hello,

We're getting closer to releasing version 2.0 of the pas2js compiler.
The major highlights of that release will be:
- Attributes
- Generics
- Async/Await support
- Better exception interception
- Class constructors

We'd again like to know what you would like to see next in pas2js:

Please fill in your preference here:

https://forms.gle/VfLbgxd8fQrU2hia8

Most items will be clear, but maybe asm [annotations] and library
support
need some small explanation:

- Asm annotations are hints to the compiler, you can tell the compiler
what
   variables your asm code uses, so the compiler won't optimize them
away.

- Library support is for NodeJS, VS Code, Atom and Electron plugin
development, as well as
   developing W3 WebComponents

What I want/need about pas2js is to install it as an stand alone
program.  I mean, no need to use Lazarus to use it, as I can do with
FPC. There are many reasons, for example to install in to a server and
use it to translate from Pascal to ECMAscript on the fly or use
makefile to build sites.

It would be wonderful.

But you can already do that? pas2js is a command line binary just like
fpc and you can call it with similar arguments (in fact Lazarus uses
that as well).

Also there is compileserver which is a variant of the simpleserver
example that does exactly what you mentioned: it automatically
compiles the Pascal code to JS code when requested.

I've tried several times and never succeeded.   I'll try again when
version 2.0 is out.

That pas2js comes preinstalled and preconfigured in Lazarus.

I have no Lazarus installed on my machine. I have been using pas2js
since the beginning (pre v1.0) as a stand alone command line program.
In fact, Lazarus integration was added later. So, it’s strange that
you can’t use pas2js from the command line.

You should probably ask here then if you have problems. So far I
personally have encountered none.

Really nice Job!

Please make it https://developers.google.com/closure/compiler
compatible. Base support is easy:
https://bugs.freepascal.org/view.php?id=37114

It's bug tracker watched? I found crazy bug something like:
 SetLength(Dynarray[1].InnerDynArray, 10);
 SetLength(Dynarray[2].InnerDynArray, 20);
 SetLength(Dynarray[3].InnerDynArray, 30);
 SetLength(Dynarray[4].InnerDynArray, 40); <- all DynArray[1..4] will
be same as DynArray[4] with InnerDynArray set to length 40 and with
same data.

BTW: Migration from my LCL desktop app based on my lib (css) to ps2js
took me only 2 weeks.

@ps
lol.jpg looks good
Sharing would be appreciated (by me) ... could also save me another 2
weeks ...

I'll ask again when I have time or need to use it. Thanks.
