Error in templates when instantiating module from file

[gmlarumbe]

The following error shows up if running verilog-ext-template-inst-auto-from-file with verilog-ts-mode:

• Internal problem; use of syntax-ppss when cache may be corrupt

This is caused by the behaviour of verilog-auto, used by the AUTO_TEMPLATE construct for the instance template:

        ;; Snippet from `verilog-auto`:
        ;; ...
        ;; If we're not in verilog-mode, change syntax table so parsing works right
        (unless (eq major-mode 'verilog-mode) (verilog-mode))

verilog-auto will switch from verilog-ts-mode to verilog-mode which should not be the intended behaviour for template instantiation.

Current error can be worked around by switching to verilog-mode before running verilog-auto and then switching back to verilog-ts-mode:

    (if (eq major-mode 'verilog-ts-mode)
        (progn
          (verilog-mode)
          (verilog-auto)
          (verilog-ts-mode))
      (verilog-auto))
