[augeas-devel] is this inifile parseable? Dupe section names, sections identified by variable inside

[Mol, Xavier (SCC)]

Hi Ron.

Augeas doesn't really take offence by sections sharing the same name, even the NodeIds could be identical, because within the Augeas 
tree representation the nodes will exist independently.

I haven't tried to parse any ini files with Augeas myself, yet. You could simply try to transform your exemplary file using the 
existing IniFile lenses and see what happens.



$ augtool -A

augtool> transform IniFile.lns_loose incl /path/to/mysql.ini

augtool> load

augtool> ls /files/path/to/mysql.ini



Ciao,

Xavier.

Hi,



I bumped into augeas while writing a puppet module for MySQL Cluster, which uses a cluster ini file which seems rather specific:



[ndb_mgmd default]

DataDir=/var/lib/mysql



[ndb_mgmd]

NodeId=51

HostName=london



[ndb_mgmd]

NodeId=52

HostName=frankfurt



[ndbd default]

DataDir=/var/lib/mysql

NoOfReplicas=3    # Number of replicas

DataMemory=80M    # How much memory to allocate for data storage

IndexMemory=18M   # How much memory to allocate for index storage



[ndbd]

NodeId=1

HostName=london



[ndbd]

NodeId=2

HostName=frankfurt



[mysqld default]



[mysqld]

NodeId=61

HostName=london



[mysqld]

NodeId=62

HostName=frankfurt



There are sections which have the same name, but are unique because of the NodeId

parameter. Before I start learning augeas, I need to know of this is doable, easy or hard to do, do I need to write a new ini file 
lens?



Thanks for your insights,



Ron Arts



BTW sorry for misusing the devel list, but the IRC channel was deserted.
