Doesn't work for systemverilog struct

[jimwang99]

Hi,

Thanks for making this great vim plugin.

I'm starting to use struct in my rtl, but it seems it cannot omin-complete the members of a struct with "abc." (using SuperTab).

Is it because the universal-ctags doesn't support struct? something like enum is supported.

Thanks.

Hi Jim,

Universal Ctags should support typedef struct, but I don't think I've added support for simple struct declarations. Would you be so kind and include an example here?

Thanks,
Vitor

Thank you for your reply. here are some examples code:

module t();

  typdef enum logic [1:0] {
    A = 2'b00,
    B = 2'b01,
    C = 2'b11,
    D = 2'b10
  } state_t;

  state_t state;
  state.<^x^o> --> nothing

  typedef struct packed {
    logic enable;
    logic [31:0] data;
  } struct_t;

  struct_t s;
  s.<^x^o> --> nothing

endmodule

and the tags file is like this, which don't have the content of struct_t, although it has the content of state_t;

I think you are not using the required arguments when generating the tags file. Please take a look at the omni completion section in the readme and help documentation, update your tags generation script and try again.

Hi vhda,

Cannot agree with you. I'm using exactly what you suggested in "README.md"

ctags *.sv --fields=+i --extras=+q -n

And here is my ctags --help info

➜  ctags --help                                                                                                                                                            9:20PM

Currently not at the pc so can't confirm, but if I remember correctly ctags arguments order matters. Try moving the *.sv to the end of the command.

Hi,

Thanks. Tried but still the same.

BTW: I'm using OSX. I download the ctags from github and compiled myself.

Hi,

I'm sorry, you are correct: Universal Ctags is still skipping the contents of structs.
Give me a week or two to take care of that.

Hi vhda,

Thank a lot. Take your time. Please let me know if you need any kind of help, such as testing or something.

This is taking longer than I'd hoped... being a recent dad is not helping out on the free time ;)
