Question

I’m using the Tabularize plugin in Vim and have the following text:

reg [321:123] ip_addr=32'h12345678;
reg [15:0] trie_data=16'h9abc;
reg [2:0] select=3'h5;

wire [3:0] nibble;
wire sram_bit;

which I want to align in this manner:

reg  [321:123] ip_addr   = 32'h12345678;
reg   [15:0]   trie_data = 16'h9abc;
reg    [2:0]   select    = 3'h5;

wire   [3:0]   nibble;
wire           sram_bit;

In words:

• left-align reg/wire in first column
• center-align bit-widths, if present, along ‘:’
• left-align signal names in third column
• = signs in the 4th column
• left-align initial values in 5th column.

So far, I’ve tried the following in order:

:Tabularize /[[0-9]*:/l1r0l0
:Tabularize /:[0-9]*]/l0l1l0
:Tabularize /=

but this combines ‘wire’ and ‘sram_bit’ in the first column instead of putting it in the first and third column respectively.

Answer 1

With two Tabularize commands it can be done like this

:Tabularize /[[0-9]*:/l1c0l0
:Tabularize /=

So here you basically use [number: as the delimiter.
