A problem when use ALE for syntax checking and gvim for vivado's editor

Question

VIM version:

VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Sep 14 2020 22:03:16)

OS information:

Microsoft Windows 10 Professional version 2004 (OS Version: 10.0.19041)

Problem Description:

I use gvim as text editor for vivado.

In Vivado, I click the verilog source file, the gvim will open the verilog file. And I use ALE for syntax checking. Everything else works, except the include statement.

For example:

There are one verilog file ( FileA.v ) and one verilog headerfile ( FileB.vh ) in the theme directory. In FileA.v, I use include:

`include "FileB.vh"

when I click FileA.v in Vivado, gvim is called to open FileA.v, then a syntax error will be reported:

[VRFC 10-3195] cannot open include file 'FileB.vh'

In fact, since FileA.v and FileB.vh is in the same directory, there should be no syntax error. And what puzzles me is that, at this time, resave this file by :w, the error will disappear.

However, close the opened file and click FileA.v in Vivado again, the problem occurs again.

Here is my _vimrc

set nocompatible
set nobackup
set noswapfile

set autochdir

Answer 1

I found a solution.

For example:

I open Vivado at D:\Vivado_Projects\WorkSpace, when I click to open verilog source file in gvim, execute :cd, then I get D:\Vivado_Projects\WorkSpace, so there if include error.

If enable set autochdir, the work directory will change to file location, then include error will disappear after using :w.

Finally I write a batch file to launch gvim:

@echo off

set /a cnt=0

:loop
set /a cnt+=1
for /f tokens^=%cnt%^ delims^=^"\/ %%i in (%1) do (
    if not "%%i"=="" (
        set A=%A%%%i\
        set B=%A%
        goto loop
    ) 
)

cd /d %B%
gvim %1 +%2
