Hello Team,
Hope you all are doing well.
I'm stuck at lineinfile module.
how to check if a variable inside each item is defined then add the line in
the file, otherwise if the regex found the match in the remote host file
but the variable inside an item is not defined then remove only that regex
matched line from the file. And continue to the next item (should not
terminate the module execution and continue to next item if variable is not
defined).
CASE:
### Here is my defaults > main.yml
```
command: /home/farrukh/idle.sh
autostart: true
autorestart: true
stderr_logfile: /var/log/idle.err.log
stdout_logfile: /var/log/idle.out.log
numprocs: 2
```
### Here is tasks > main.yml
```
- name: "Update Job Parameters in .conf file"
lineinfile:
path: "{{ supervisor_config_path }}/job_{{ job_name }}.conf"
backrefs: yes
regexp: "{{ item.regexp }}"
line: "{{ item.line }}"
when: item.line is not search(omit)
with_items:
- { regexp: '^command', line: "command={{ command | d(omit) }}M" }
- { regexp: '^autostart', line: "autostart={{ autostart | d(omit) }}" }
- { regexp: '^autorestart', line: "autorestart={{ autorestart | d(omit)
}}M" }
- { regexp: '^stderr_logfile', line: "stderr_logfile={{ stderr_logfile |
d(omit) }}" }
- { regexp: '^stdout_logfile', line: "stdout_logfile={{ stdout_logfile |
d(omit) }}" }
- { regexp: '^numprocs', line: "numprocs={{ numprocs | d(omit) }}" }
```
### Here is the file on the remote host "job_idle.conf"
```
[program:job_idle]
command=/home/ubuntu/idle.sh
autostart=true
autorestart=true
stderr_logfile=/var/log/idle.err.log
stdout_logfile=/var/log/idle.out.log
```
Now, for instance, If I comment out the variable "autorestart" from the
defaults > main.yml. like below:
### defaults > main.yml
```
command: /home/farrukh/idle.sh
autostart: true
#autorestart: true
stderr_logfile: /var/log/idle.err.log
stdout_logfile: /var/log/idle.out.log
numprocs: 2
```
Then running playbook, should get the desired result of job_idle.conf like
below:
## The file on the remote host "job_idle.conf"
```
[program:job_idle]
command=/home/ubuntu/idle.sh
autostart=true
stderr_logfile=/var/log/idle.err.log
stdout_logfile=/var/log/idle.out.log
```
It should remove the line autorestart. As the variable "autorestart" was
commented out from defaults > main.yml and not defined.
It is this case achievable with this module?
