I've sent a PR. Do you need/want some help on this one ?

[0xAX]

Hello @pap,

thank you for the PR, i'm very appreciate your help 👍 I mainly working on Weber development now, so exhaml is in very early stage. Need to finish parser and make generator.

I can add you to elixir-web for easy contribution

@0xAX Don’t mention it, i’m glad to help out…
i’ve been “disconnected” from weber because i was finishing a big project. I intend to be more active !
As for exhaml i’m excited about it because i’m maily a Ruby on rails developer and i don’t like the verbosity of erb templates or any kind of templating that requires full html tag madness !

Initial tokenizer is done, exhaml already can compile haml like:

  def test2 do
    """
    %section
      %h1
        %div{ test => test, test2 => test2}
        asd
    %div
    """
  end

  def test3 do
    """
    %ul
      %li
        %a{:href => "#devices-tab"}Devices
      %li
        %a{:href => "#options-tab"}System Options
      %li
        %a{:href => "#reports-tab"}Reports
      %li
        %a{:href => "#notes-tab"}Notes
    """
  end

  def test4 do
    """
    %div{ class => main }
      %div{class = int1 }
      %div{class = int2, id = int22 }
    """
  end

Next point is - generator

@0xAX take a look at this gist ... i used Exhaml to parse a haml file i use in one of my rails apps.

https://gist.github.com/pap/74575d2f451be5e26a6f

There are a few issues ...

You based your work on the original haml code ?
I've cloned it and will take a look at it ...
By compile haml you mean take haml input parse it and output html right ?

[0xAX]

Thanks, will check it.

By compile haml you mean take haml input parse it and output html right ?

No i mean convery haml code to the internal elixir-terms based structure and only than to html

[0xAX]

@pap Hard to read. Can you give me please your plain HAML code from gist

[pap]

@0xAX about the html comments:

=# this is haml commented
-# this is also haml commented

You plan to output commented html right ?

[0xAX]

@pap,yes i know, now there is only -# support in parser. Comments stills in structure after parsing, but removing in generation time

[pap]

@0xAX
About the haml source:
Sorry for the poor formatting ... you can read it here
https://gist.github.com/pap/361bdea0f45e7b9690be

About comments:
I think we could use the - and = semantic ...
Comments in haml starting with -# should not output to html but if you comment with =# the comments should be added ...i know its probably a unneeded step since the generated html will only be seen in client ... but as a developer i might want the generated html to have some kind of info ... what's your thought on this ?

[0xAX]

Thanks, i will look.

Current parser is not counting identations, so we can't know where comments are finish, so i decided to leave it in structure.

[pap]

@0xAX what do you mean about not counting indentation?
I'll take a look but i think the general approach for the parser should be "parsing" each indented block.

%A 
    %a1
    %a2
        a2.1
%B
    %b1
        b1.1
    %b2

We should parse A into a structure, then B into another. Each level of indentation should be "nested" inside its "parent"

This is good because we can have "partials" rendered for example:

file main.html

%p
  %b
    Bold Title
  %i
    Italic content
  = render "test"

File _test.html (partial)

%h1
  Title

The result would be

%p
  %b
    Bold Title
  %i
    Italic content
  %h1
    Title

Hi @0xAX did you already took a look at this https://github.com/nurugger07/calliope ?
