问题
I am trying to have verilog mode indent everything using 2 spaces except decls and always. This is what I added to my .emacs:
;; `define are not indented
(setq verilog-indent-level-directive 0)
;; always, initial etc not indented
(setq verilog-indent-level-module 0)
;; logic declarations are not indented
(setq verilog-indent-level-declaration 0)
;;2 space indent
(setq verilog-indent-level 2)
;; no indent on list and no indent when on multiple lines
(setq verilog-indent-lists nil)
(setq verilog-cexp-indent 0)
These is the result on a test module
`ifndef MY_MODULE_SV
`define MY_MODULE_SV
module my_module #(
parameter MyPar1 = 16,
parameter MyPar2 = 32
) (
input logic clk,
input logic reset,
//comment indented weirdly
output logic [3:0] result
);
logic [3:0] count;
always @(posedge clk) begin
//comment indented ok
if (reset) begin
count <= 0;
result <= 0;
end
else begin
result <= count;
count <= count+1;
end
end
endmodule; // my_module
`endif
The part that is not correct are the port and parameter list.
Also the declaration of count gets aligned to the port declarations, which is strange.
I would like this to look like:
module my_module #(
parameter MyPar1 = 16,
parameter MyPar2 = 32
) (
input logic clk,
input logic reset,
//result signal
output logic [3:0] result
);
I am using emacs 24.3.1 I am not sure how to tweak this using only the variables provided by the verilog mode, any suggestion?
回答1:
This doesn't exactly match your requested layout, but what I do is put the #( below the module keyword and split the end paren from the parameter list and the begin paren for the port list onto separate lines. The result is below. All of my indentation is for 3 spaces, but you could tweak that to suit your needs:
module my_module
#(
parameter MyPar1 = 16,
parameter MyPar2 = 32
)
(
input logic clk,
input logic reset,
//comment indented weirdly
output logic [3:0] result
);
logic [3:0] count;
always @(posedge clk) begin
//comment indented ok
if (reset) begin
count <= 0;
result <= 0;
end
else begin
result <= count;
count <= count+1;
end
end
endmodule; // my_module
The verilog mode related section of my .emacs file is below:
