default indent (question)

[brayden-jo]

Thank you for making a good plugin. I have a simple question, I review the document but I didn't find a proper solution yet.

This plug-in seems to use default 4-space of indent. Can I turn-off this feature ? We usually the coding style which starts with column 0. Please check below two coding style.

// current
module (
    clk, 
    reset_n,
    i_data,
    o_data
);

    input clk;
    input reset_n;

endmodule

// new
module (
    clk, 
    reset_n,
    i_data,
    o_data
);

input clk;                               // no indent
input reset_n;

always @ (posedge clk or negedge reset_n) begin
    if (!reset_n) begin
        o_data <= 4'b0;
   end else begin
       o_data <= i_data;
   end
end

endmodule

I added below line to .vimrc but it does not works.

let g:verilog_disable_indent_lst = "module,class,interface"

Hi @brayden-jo,

That should work exactly as you need if you also include "eos" in the comma separated list. And the plugin will follow by default your 'shiftwidth' setting. This what I get with set sw=2 and let g:verilog_disable_indent_lst="eos":

// new
module (
  clk,
  reset_n,
  i_data,
  o_data
);

  input clk;                               // no indent
  input reset_n;

  always @ (posedge clk or negedge reset_n) begin
    if (!reset_n) begin
      o_data <= 4'b0;
    end else begin
      o_data <= i_data;
    end
  end

endmodule

This what I get with let g:verilog_disable_indent_lst="eos,module":

// new
module (
  clk,
  reset_n,
  i_data,
  o_data
);

input clk;                               // no indent
input reset_n;

always @ (posedge clk or negedge reset_n) begin
  if (!reset_n) begin
    o_data <= 4'b0;
  end else begin
    o_data <= i_data;
  end
end

endmodule

Please try disabling other plugins and/or settings that could be affecting this behavior.

Hope this helps, Vitor

@vhda , Thanks you for your reply.

When I set the below setting within the vim, it works well.

let g:verilog_disable_indent_lst = "module,class,interface"

But as I mentioned before, it doesn't work with .vimrc file. I delete all plugins and use the simplest .vimrc as below:

call plug#begin('~/.vim/plugged')
    Plug 'vhda/verilog_systemverilog.vim'
call plug#end()

let g:verilog_disable_indent_lst="eos,module"

Currently I use the this command in the vim to apply the let g:~~~~ configure.

source ~/.vimrc

I am using the CentOS7 default vim.

Instead of sourcing vimrc just open vim and run the following command:

:let g:verilog_disable_indent_lst

Does this show the value you defined in the vimrc? Then try opening a verilog file and check this command again. Could you also confirm the filetype value in the verilog file?

:set filetype

[brayden-jo]

@vhda , when I run the vim and run the following command:

:let g:verilog_disable_indent_lst

default options is shown as below

g:verilog disable indent lst eos

let g command in .vimrc doesn't seem to work.

when i run the :set filetype, I can see the 'filetype=verilog systemverilog'

Thanks.

Hi @brayden-jo, Sorry for the delayed reply.

Are you saying that g:verilog_disable_indent_lst variable does not work in .vimrc. But what about setting it dynamically? That is, if you open a Verilog file and set this variable, do you see indentation start to work correctly? I'm running out of ideas. Everything looks good and it should be working!

[brayden-jo]

@vhda ,

dynamically setting doesn't work too for the *v/sv file. For reference, my colleague using centos7 also shows the same problem.

Is there any workaround to fix the plugin directly?

"module,class,interface" is the default list for the our coding style.

[vhda]

I've just tried on my side with a clean .vimrc and everything is working as expected. I can try it in CentOS during this week just to confirm, but I'm really confident that shouldn't be the issue. Using the example file above, try the following:

gg=G

This will indent the complete file. This is the result with default settings: Then I set the variable to "eos,module" and get this: after re-indenting:

[netvolcano]

I had the same issue and found a way to solve it. I suggest to add the following lines in the plugin\verilog_systemverilog.vim. When I put my setting the .vimrc file, this following statements will not overwrite my setting.

" Global plugin settings
if !exists("g:verilog_disable_indent_lst")
    let g:verilog_disable_indent_lst="eos"
endif
