example doesn't work on Debian with installed freeling v3.1

[filterfish]

I tried the example from the README but it returns an empty array. FreeLing is installed from the dpkg downloaded from the FreeLing site. MeCab isn't installed.

dpkg -l | grep freeling
ii  freeling     3.1    amd64        Library of natural language analysis facilities.

I piped the following through pry:

require 've'
provider = Ve::Manager.provider_for(:en, :words)
parse = provider.parse('I like melons.')
parse.send(:words)

I get:

[1] pry(main)> require 've'

I initially thought it was -f /usr/share/FreeLing/config/en.cfg flag as this path doesn't exist. The path is /usr/share/freeling/config/en.cfg. So I'm symlinked /usr/share/FreeLing to /usr/share/freeling but it made no difference.

If I run it on the command line it works analyze seems to return something sensible (I've never used FreeLing before):

echo "I like melons." | analyze --locale=en_AU.UTF-8 -f /usr/share/FreeLing/config/en.cfg --flush --nonumb --nodate
I i PRP 1
like like IN 0.867653
melons melon NNS 1
. . Fp 1

I wondered if it might be the locale option (I don't have en_US.UTF-8 installed) and analyze fails without it but after adding locale it still returned an empty array.

Hmm, it might be that something has changed in FreeLing 3.1. I think it was on version 2.9 when I wrote this code. I'll see if I can reproduce locally with 3.1 and fix.

I have tried with Freeling 3.1 and it's working for me.

It's odd that your Ve is trying to use /usr/share/FreeLing when it should use /usr/share/freeling though.

Try forcing the provider class to use the correct path by running this right after require 've': Ve::Manager.set_default_config_for(Ve::Provider::FreelingEn, {:flags => "-f /usr/local/share/freeling/config/en.cfg --flush --nonumb --nodate"})

Then try

provider = Ve::Manager.provider_for(:en, :words)
parse = provider.parse('I like melons.')

Here's the output I get:
