Create cpp tags for code navigation on spacemacs

Aim

We would like to use cscope and gtags to create tags for c++ development.

prepareSpacemacsTags.sh

#!/bin/bash
buildPath="$PWD"

# remove old tags
rm ${buildPath}/GPATH
rm ${buildPath}/GRTAGS
rm ${buildPath}/GTAGS

rm ${buildPath}/cscope.files
rm ${buildPath}/cscope.out
rm ${buildPath}/cscope.in.out
rm ${buildPath}/cscope.po.out

# make tags
echo "######### make GTag"
gtags
echo "######### make cscope"
find . -name "*.cc" -o -name "*.c" -o -name "*.cpp" -o -name "*.h" -o -name "*.hpp" > cscope.files
cscope -q -R -b -k -i cscope.files

Usage

$ cd /path/to/project/root
$ prepareSpacemacsTags.sh

prepareTags.YourProject.sh

#!/bin/bash
basePath=`pwd`
tempTagPath="$basePath/../tempTagFolder"
appFolders=("APPFolderName") # filter out

# move all folders beyond root
if [ ! -d "$tempTagPath" ]; then
    mkdir "$tempTagPath"
fi
if [ ! -d "$tempTagPath/app" ]; then
    mkdir "$tempTagPath/app"
fi
for folder in ${appFolders[@]}; do
    nextFolder="$basePath/app/$folder"
    mv $nextFolder $tempTagPath/app
done

prepareSpacemacsTags.sh

mv $tempTagPath/app/* ./app

if [ -d "$tempTagPath/app" ] && [ -z "$(ls -A $tempTagPath/app/)" ]; then
    rm -rf $tempTagPath/app
else
    echo "No need to have further action $tempTagPath/app"
fi
if [ -d "$tempTagPath" ] && [ -z "$(ls -A $tempTagPath)" ]; then
    rm -rf $tempTagPath
else
    echo "No need to have further action $tempTagPath"
fi

Usage

$ cd /path/to/project/root
$ ls
./app
./lib
$ prepareTags.YourProject.sh
