infos/description = resolver for parts in a file configuration file

The blockresolver can be used to only resolve a tagged block inside a configuration file.

Implementation details

blockresolver extracts the requested block from the configurations file and writes it into a temporary file. Afterwards Elektra will only work on the temporary file until kdbSet is called. On kdbSet the contents of the temporary file will be merged with parts outside of the requested block from the original file.

Usage

`kdb mount -R blockresolver /path/to/my/file /mountpoint -c identifier="identifier-tag"`

where identifier specifies the tag blockresolver will search for in the configuration file.

A block consists of 2 parts:

beginning: the identifier suffixed with start
end: the identifier suffixed with stop

Limitations

Currently the identifier must be unique.

Example

```

Backup-and-Restore:system/examples/blockresolver

sudo kdb mount -R blockresolver /tmp/test.block system/examples/blockresolver -c identifier=">>> block config" ini

create testfile

cat > /tmp/test.block << EOF \ text\ more text\ some more text\

block config start\

[section1]\ key1 = val1\ [section2]\ key2 = val2\

block config stop\

text again\ and more text\ text\ EOF

check testfile

cat /tmp/test.block #> text #> more text #> some more text #> >>> block config start #> [section1] #> key1 = val1 #> [section2] #> key2 = val2 #> >>> block config stop #> text again #> and more text #> text

only the block between the tags is read!

kdb export system/examples/blockresolver ini #> [section1] #> key1 = val1 #> [section2] #> key2 = val2

add a new key to the resolved block

kdb set system/examples/blockresolver/section1/key12 val12

cat /tmp/test.block #> text #> more text #> some more text #> >>> block config start #> [section1] #> key1 = val1 #> key12 = val12 #> [section2] #> key2 = val2 #> >>> block config stop #> text again #> and more text #> text

cleanup

kdb rm -r system/examples/blockresolver sudo kdb umount system/examples/blockresolver ```
