# Subject: [PATCH] Add Verilog nanorc file for syntax highlighting
|
|
|
|
# This adds a verilog.nanorc file for syntax highlighting of Verilog
|
|
# and SystemVerilog code. It is based off of the nanorc files for
|
|
# Python and C.
|
|
|
|
# All keywords in both Verilog (*.v, *.vh) and SystemVerilog (*.sv,
|
|
# *.svh) are listed. Compiler directives (commands beginning with a
|
|
# backtick) and builtin functions are also colorized.
|
|
|
|
# Possibly the color scheme could use some work, but this is at least
|
|
# a starting point. I based verilog.nanorc off of c.nanorc and
|
|
# python.nanorc.
|
|
|
|
