-This script handles variables and nested values (hashes and arrays).
-You can create several configuration sets (storages) to isolate them.
-
-Help
-
- --help or -h or -?
- show this help and abort.
-
- --version or -v
- show the version.
-
-Storage parameters
-
- --storage NAME
- Set a storage to use. Allowed chars are a-z and 0-9.
- Default is a storage named "default".
- You can set an evironment variable CFGSTORAGE to override
- the default (= to skip --storage NAME).
-
- --list
- List existing storages.
-
- --flush
- delete current storage data
-
- --show
- show the current config entries as plain text
-
- --json
- show config entries as json.
- Warning: it is implemented in Bash - can be slow on more data
-
-Create | read | update | delete variables
-
- --set VARNAME VALUE
- Set a variable and its value.
- If it does not exist then it will be created.
- If it exist then it will be overwritten with the new value.
-
- For the values you can force the type:
- * Use single and double quotes to set a string, i.e.
- \$ $self --set my_string '"hello world"'
-
- * Quote the doublequotes to expand variables, i.e.
- \$ $self --set my_string2 \"\${my_string2}\"
-
- * use no quoting vor integers and values
- \$ $self --set number_cpu 8
-
- * use barackets in quotes to set an array
- \$ $self --set my_array '[8, 12, 16]'
-
- Use a "." (dot) in varname to create a hierarchy, i.e.
- \$ $self --set host.os '"linux"'
-
- --setfile VARNAME FILENAME
- Set an input file to show its content
-
- --add VARNAME VALUE
- Add VALUE as array element to VARNAME.
- It fails if VARNAME does not exist or isn't an array.
- $ confighandler.sh --add my_array 20
-
- --get VARNAME
- Show value of the given variable.
-
- --delete VARNAME
- delete a variable.
-
-You can concatenate all parameters. So you can use --show before
-and after an --set action to see the differences.
-\$ $self --show --set hello '"world"' --show
-
-You get additional infos on STDERR. To get plain data send STDERR
-to /dev/null
-\$ $self --show 2>/dev/null
