Cannot get Auto-complete to work

[thagen]

I'm trying to get the editor to do autocomplete and I'm having zero luck. I can't get the real-time to work at all no matter when I type '.' so I must be missing something basic. If I use the manual "tags -> Autocomplete current word..." it pops works for some.

Which leads me to my next question - I'm using this for Verilog and it's not picking up the variable names - just the top level modules. How do I get it to do that?

Any info greatly appreciated. Thanks-

Since the completion works manually for some, but not automatically suggests to me this sounds like a bug in Zeus

Now I also suspect this should be a fairly easy bug to fix, but to get this fixed I will need some help from you.

What I would need is a simple one file example of Verilog code containing typical examples auto-completions you would expect to see working.

The code does not need to compile, it just needs to contain those code snippets that should auto-complete.

If you can post that file here as an attachment or send it to me as e-mail that would be great.

With that code it should be fairly easy to figure out at this end why this is not working

I had a quick look at this auto-complete issue.

What I found was this snippet of code does not autocomplete:

Code: Select all

primitive prim_input (c,a,b);
      output c;
endprimitive

But this one does autocomplete:

Code: Select all

function func_input (c,a,b);
      output c;
endfunction

The reason for the difference is the first example is not identified by the ctags tool where as the second one is.

I suspect the error you are seeing is probably a similar issue relating to the information generated by the ctags tool.

To fix these sort of ctags issues requires simple code examples, just like the ones shown above.

Here is a simple test case I was trying -

Code: Select all

module MAX10_ST (
output reg [7:0] dout,
input wire rst_n,
input wire clk
);

reg [7:0] din ;
wire clk_int ;

always @ (posedge clk or negedge rst_n)
begin
if (~rst_n) dout <= `DELAY 8'h00 ;
else dout <= `DELAY dout + 1 ;
end //always
endmodule

If I type "MAX" then Ctrl-F1, it gives the autocomplete option of "MAX10_ST"
If I type "cl" then Ctrl-F1, it gives the autocomplete option of "clk_int" but not "clk"
If I type "rst" then Ctrl-F1, I would expect the option of "rst_n", but I get nothing.

All this is manual. If I try "automatic" by typing '.' I get nothing
If I type "MAX." I get nothing.
If I type ".MAX" I also get nothing.

I'm assuming one of those should have triggered the auto-complete. Any insight greatly appreciated. Thanks

The main reason this is not working was because, as suspected the ctags.exe is not generating the correct tags information.

I found an alternative ctags tool here: https://github.com/universal-ctags/ctags

Building that tool creates this alternative xtags.exe executable: http://www.zeusedit.com/z300/xtags.zip

So you need replace the xtags.exe found in the C:\Program Files (x86)\Zeus\ folder with the one from the download link above.

If I type "MAX" then Ctrl-F1, it gives the autocomplete option of "MAX10_ST"
If I type "cl" then Ctrl-F1, it gives the autocomplete option of "clk_int" but not "clk"
If I type "rst" then Ctrl-F1, I would expect the option of "rst_n", but I get nothing.

With that new xtags.exe these should be fixed.

All this is manual. If I try "automatic" by typing '.' I get nothing
If I type "MAX." I get nothing.
If I type ".MAX" I also get nothing.

I'm not sure what you mean by this

The way the '.' works is defined by languages like C++, C#. Python etc and for it to work you need some sort of class construct.

Here is an simple example:

Code: Select all

class Example
{
public:
        int a;
        int b;
}

This would then allow the '.' to intellisense in code like this:

Code: Select all

    Example test;

    test.   << the autocomplete will display a and b as options

But for the Verilog example you have provided, the tags information does not contain any such class information.
