# MODIFY A CONFIG FILE

#=================================================
### `ynh_replace_string` is used to replace a string in a file.
### (It's compatible with sed regular expressions syntax)
### You can add specific configuration files.
###
### Typically, put your template conf file in ../conf/your_config_file
### The template may contain strings such as __FOO__ or __FOO_BAR__,
### which will automatically be replaced by the values of $foo and $foo_bar
###
### ynh_add_config will also keep track of the config file's checksum,
### which later during upgrade may allow to automatically backup the config file
### if it's found that the file was manually modified
###
### Check the documentation of `ynh_add_config` for more info.

#=================================================
# STORE THE CONFIG FILE CHECKSUM
#=================================================
### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.
# Calculate and store the config file checksum into the app settings
ynh_store_file_checksum --file="$final_path/CONFIG_FILE"
### For more complex cases where you want to replace stuff using regexes,
### you shoud rely on ynh_replace_string (which is basically a wrapper for sed)
### When doing so, you also need to manually call ynh_store_file_checksum
