Homestead pass parameters to after.sh for xdebug autoconfigure - shell

Question

I put the following to after.sh to autoconfigure the Xdebug form project:
#!/bin/sh
echo "Configuring Xdebug"
ip=$(netstat -rn | grep "^0.0.0.0 " | cut -d " " -f10)
xdebug_config="/etc/php/$(php -v | head -n 1 | awk '{print $2}'|cut -c 1-3)/mods-available/xdebug.ini"
echo "IP for the xdebug to connect back: ${ip}"
echo "Xdebug Configuration path: ${xdebug_config}"
echo "Port for the Xdebug to connect back: ${XDEBUG_PORT}"
echo "Optimize for ${IDE} ide"
if [ $IDE=='atom' ]; then
echo "Configuring xdebug for ATOM ide"
if [ -z ${xdebug_config} ]; then
sudo touch ${xdebug_config}
fi
sudo cat <<EOL >${xdebug_config}
zend_extension = xdebug.so
xdebug.remote_enable = 1
xdebug.remote_host=${ip}
xdebug.remote_port = ${XDEBUG_PORT}
xdebug.max_nesting_level = 1000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true
xdebug.remote_log=xdebug.log
EOL
fi
Also I have the following settings to Homestead.yaml:
ip: 192.168.10.10
memory: 2048
cpus: 1
provider: virtualbox
authorize: ~/.ssh/id_rsa.pub
timeout: 120
keys:
- ~/.ssh/id_rsa
folders:
-
map: /home/pcmagas/Kwdikas/php/apps/ellakcy_member_app/
to: /home/vagrant/code
sites:
-
map: homestead.test
to: /home/vagrant/code/web
type: symfony
databases:
- homestead
- homestead-test
variables:
- key: database_host
value: 127.0.0.1
- key: database_port
value: 3306
- key: database_name
value: homestead
- key: database_user
value: homestead
- key: database_password
value: secret
- key: smtp_host
value: localhost
- key: smtp_port
value: 1025
- key: smtp_user
value: no-reply#example.com
- key: IDE
value: atom
- key: XDEBUG_PORT
value: 9091
name: ellakcy-member-app
hostname: ellakcy-member-app
But for some reason it cannot read the values from enviromental variables defined in Homestead.yml as seen in the following output:
ellakcy-member-app: IP for the xdebug to connect back: 10.0.2.2
ellakcy-member-app: Xdebug Configuration path: /etc/php/7.2/mods-available/xdebug.ini
ellakcy-member-app: Port for the Xdebug to connect back:
ellakcy-member-app: Optimize for ide
ellakcy-member-app: Configuring xdebug for ATOM ide
As you can see it fails to read values from the IDE and XDEBUG_PORT do you knwo why and how I can fix that?

You can put a parse_yaml.sh:
#!/bin/sh
parse_yaml() {
local prefix=$2
local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo #|tr # '\034')
sed -ne "s|^\($s\)\($w\)$s:$s\"\(.*\)\"$s\$|\1$fs\2$fs\3|p" \
-e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p" $1 |
awk -F$fs '{
indent = length($1)/2;
vname[indent] = $2;
for (i in vname) {if (i > indent) {delete vname[i]}}
if (length($3) > 0) {
vn=""; for (i=0; i<indent; i++) {vn=(vn)(vname[i])("_")}
printf("%s%s%s=\"%s\"\n", "'$prefix'",vn, $2, $3);
}
}'
}
And into after.sh
#!/bin/sh
# include parse_yaml function
. parse_yaml.sh
# read yaml file
eval $(parse_yaml zconfig.yml "config_")
# access yaml content
echo $config_development_database

Answer 2

In my case I tried the approach of having a file named xdebug.conf where I place anything that the default xdebug.conf needs to get rewritten:
zend_extension = xdebug.so
xdebug.remote_enable = 1
xdebug.remote_host = $ip
xdebug.remote_port = 9091
xdebug.max_nesting_level = 1000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true
xdebug.remote_log=xdebug.log
The $ip indicates the auto-replaced value with the correct ip in order for the xdebug to get connected into. The script that actually updates the xdebug configuration with the appropriate values is this one in my after.sh
#!/bin/sh
code_path="/home/vagrant/code"
cd $code_path
# Some other bootstrapping
echo "Configuring Xdebug"
ip=$(netstat -rn | grep "^0.0.0.0 " | cut -d " " -f10)
xdebug_config="/etc/php/$(php -v | head -n 1 | awk '{print $2}'|cut -c 1-3)/mods-available/xdebug.ini"
echo "Xdebug config file ${xdebug_config}"
if [ -f "${code_path}/xdebug.conf" ]; then
echo "Specifying the ip with ${ip}"
sed "s/\$ip/${ip}/g" xdebug.conf > xdebug.conf.tmp
echo "Moving Into ${xdebug_config}"
cat xdebug.conf.tmp
sudo cp ./xdebug.conf.tmp ${xdebug_config}
else
echo "File not found"
fi
The last step is to .gitignore any xdebug.conf* file. So now the developer has to create his own xdebug.conf.
