Use of the -p flag about liquigraph HOT 11 CLOSED

Thanks for the report!

-p works interactively, and is used as follows:

1. liquigraph -c /my/changelog.xml -g jdbc:neo4j://my.host:7474 -u myUser -p
2. a prompt appears: you must type your password (it remains hidden)

If I understand well, you would like to have a non-interactive password parameter?

from liquigraph.

If so, we could adapt step 1 to also support the following execution:

echo "my_password" | liquigraph -c /my/changelog.xml -g jdbc:neo4j://my.host:7474 -u myUser -p

It would require a tweak to the existing shell script (and possibly Batch one).
And probably something with JCommander too.

What do you think? Would you like to push a change? :-)

from liquigraph.

Yeah - effectively I want to be able to do:
liquigraph -c /my/changelog.xml -g jdbc:neo4j://my.host:7474 -u myUser -p password

Happy to take a look at the code and contribute. I'm an recovering java dev and current go coder - it'll take me a while to set up a java env again :o)

Just a JDK 7 and Maven 3.x is enough :-)
Feel free to reach me if you have any questions 👍

To get my required functionality is a fairly small easy change.

The issue I raised relates to the (password = true) jcommander annotation on the password field in LiquigraphCli (doc:http://jcommander.org/#Types_of_options). If I remove the (password = true) it connects to neo4j and liquigraph can run in the changeset using:

liquigraph -c /my/changelog.xml -g jdbc:neo4j://my.host:7474 -u myUser -p password

Obviously I don't want to push this in as it would likely break other peoples installations/setups. What would your preferred approach be? New flag?

from liquigraph.

I need to dig a little more into JCommander sources to see if I can get a conditionally interactive parameter. I like the current password behaviour: password remains hidden and out of shell history. But your usecase is also 100% legit and we need a configurable behaviour for that.

from liquigraph.

Good news! I found a way that requires no code change and does not compromise your password.
Just run:

 $> touch my_password.txt
 # write your password there + chmod appropriately ;-)
 $> liquigraph -c /path/to/changelog.xml -g jdbc:neo4j://localhost:7474 -u my_user -p < my_password.txt

Would you like to send a Pull Request (see gh-pages branch) to update the documentation to reflect this?

from liquigraph.

Great. That works. Thanks for that.

I don't mind changing the documentation but I can't see it :D apologies it's probably in a really obvious place.

from liquigraph.

The online documentation is here.
The documentation sources are here.

You can simply open the local index.html to see your changes.

Cheers. Done. Let me know if there's any issues.

I'd be happy to include information on how we dockerized liquigraph too if wanted.

Would you mind sending me a Twitter DM? I'm curious about what you did :-)
