Subject [jira] Closed: (COUCHDB-276) Should have a command line flag to add to the erlang load path
Date Tue, 03 Mar 2009 01:33:56 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-276?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jan Lehnardt closed COUCHDB-276.
--------------------------------

    Resolution: Won't Fix

You can set additional erlang args via environment variables.

i.e. ERL_AFLAGS="-pa /path/to/libs" couchdb
or ERL_LIBS="/path/to/liibs" couchdb

will do.

>From man erl:

Environment variables
[...]
ERL_AFLAGS
The content of this environment variable will be added to the beginning of the command line
for erl.
The -extra flag is treated specially. Its scope ends at the end of the environment variable
content. Arguments following an -extra flag are moved on the command line into the -extra
section, i.e. the end of the command line following after an -extra flag.

ERL_ZFLAGS and ERL_FLAGS
The content of these environment variables will be added to the end of the command line for
erl.
The -extra flag is treated specially. Its scope ends at the end of the environment variable
content. Arguments following an -extra flag are moved on the command line into the -extra
section, i.e. the end of the command line following after an -extra flag.

ERL_LIBS
This environment variable contains a list of additional library directories that the code
server will search for applications and add to the code path. See code(3).

> Given that the couchdb script allows new configuration files to be loaded, I think you
should be able to add to the erlang load path a similar fashion, so that the new configuration
files can refer to erlang code not included with couchdb itself.
