Hi All,
Ref [1] w.r.t some patchset seen on linux driver project having a
similar condition of ton of camelcasing and [2],
Can we consider running the following script for DSPBridge code? or if
there are some more improvements folks can think of..
-----
#!/bin/bash
# Silly little script to replace CaMELCaSInG to lower_casing
# Half a zillion thoughts later,
# why not use ctags which has c interpreter already to do
# function identification for us?
if [ ! -r 'tags' ]; then
echo "Sorry.. no tags file!"
exit 1
fi
if [ ! -r "$1" ]; then
echo "I need a directory or a file for replacing.."
exit 2
fi
DIR_FILE=`echo "$1"|sed -e "s/\//\\\//g"`
# tags have the following notation in field 4 (tab seperated)
# e - enum value
# d - define
# f - function
# F - File itself
# g - enum type
# m - structure parameter
# p - prototype
# r - kconfig define(refered)
# s - structure type
# t - typedefined variable
# v - variable
# x - extern defined variable
# we can choose to have different rules:
# rename rule i am going to follow:
# Any define -> convert camelcase to lower_case_define->convert to caps
# Any function, enum,struct param,prototype,struct type, typedef
var,extern def ->
# camel_case to lower_case_define
# All files will be made unix file only (no point in dos + unix mixtures..)
#**
#* @brief - changes camel casing to ones with smaller case
#*
