We are re-writing the plugins with the plugins system so we didn't finish yet :)

[semicode-ltd]

Sure, I am having an issue getting sarah to run on my ubuntu system. I am getting the following errors

when I run valac main.vala
main.vala:27.3-27.5: error: The type name App' could not be found
App app = new App ();
^^^
`

============================================================================

and when I run sarah.vala
sarah.vala:53.10-53.13: error: The symbol Peas' could not be found
public Peas.Engine engine;
^^^^
sarah.vala:54.10-54.13: error: The symbol Peas' could not be found public Peas.ExtensionSet extension_set; ^^^^ sarah.vala:55.10-55.13: error: The symbol Peas' could not be found

I eagerly await your response

I prefer the plugins in python if its all the same Im really good with it.

[semicode-ltd]

You can install the dependencies and run sarah as following :
make all
make install
cd bin
./sarah pluginname

[semicode-ltd]

Yes You can Write any Plugin You want in Python

[KyleSponz]

Got the following when I tried to run the make file :
sudo make all valac -o libsarah.so --library=sarah -H ./bin/sarah.h --gir=Sarah-1.0.gir -X -shared -X -fPIC --pkg libpeas-1.0 --pkg gmodule-2.0 sarah.vala -d ./bin /home/kyle/PycharmProjects/sarah/bin/sarah.vala.c:31:26: fatal error: libpeas/peas.h: No such file or directory compilation terminated. error: cc exited with status 256 Compilation failed: 1 error(s), 0 warning(s) Makefile:11: recipe for target 'sarahLib' failed make: *** [sarahLib] Error 1

[msupercoder]

You need to install libpeas-dev package :)

[KyleSponz]

well it seems that helped some, it seems that the error is as follows and centered around the vala-extension.vala file found in the /plugins directory:

Thanks for being so awesome with my new guy questions, Ive never even heard of vala till I started playing around with sarah. Im having a blast regardless

[semicode-ltd]

its Okay Friend !
you need to install vala compiler itself so check this link i think its useful for you :
http://askubuntu.com/questions/612342/how-to-install-the-vala-environemt

[semicode-ltd]

Sorry Friend this was a problem in the make file clone the repo again and try now

[KyleSponz]

Ran this got the valac package:

[msupercoder]

yes you are using an old repo! we made several fixes clone the repo now and try again :)

[msupercoder]

do as following :
cd sarah/
make
make install
cd bin
export LD_LIBRARY_PATH=.
export GI_TYPELIB_PATH=.
./sarah hi am kylespons

[KyleSponz]

doh got it running!!!!!!!

I added some instructions to the readme and created a pull request thanks!!!!

[nikssardana]

Hey.
Can anyone guide me on how to write a plugin for sarah?
Thanks!

[brunohanai]

Hi,

I'd like to know this too. Here is what I did:

Created a dir in plugins dir ("/plugins/imdb")

Created a file named imdb.plugin (I dont know what each key=value really means):

[Plugin]
Module=imdb
Loader=python3
Name=imdb
Description=get movie's info

Created a file named imdb.py:

import os
import sys

import gi
gi.require_version('Peas', '1.0')
gi.require_version('Sarah', '1.0')
from gi.repository import GObject, Peas, Sarah

import omdb

class ImdbPlugin(GObject.Object, Sarah.IExtension):
    __gtype_name__ = 'ImdbPlugin'

    object = GObject.property(type=GObject.Object)

    def do_activate(self, args, argv):
        print(args)

    def do_deactivate(self):
        pass

The command now appears on sarah list command.

But I got the error:

(process:765): libpeas-WARNING **: Error importing plugin 'imdb':
ImportError: No module named 'omdb'
** (process:765): CRITICAL **: sarah_iextension_activate: assertion 'self != NULL' failed

PS: I installed omdb with pip install omdb

Please help me with that guys.

[aissat]

hi @brunohanai it's worked
try
sudo pip3 install omdb

[brunohanai]

Thanks!

And can you explain the *.plugin file?

[0vulns]

Imagine with me that you want to create a plugin to called "foo" to print Hi brunohanai , The *.plugin file would be something like this:
Before we go ahead we need to know some rules about plugin file:

• The file name and Module name must be in lowercase [a-z]
• So far Sarah support python3 & c loader only.
  The plugin file:

[Plugin]
Module=foo
Loader=python3
Name=foo
Description=foo and bar!

I think Name is the name of command

foo.py

import gi
gi.require_version('Peas', '1.0')
gi.require_version('Sarah', '1.0')
from gi.repository import GObject, Peas, Sarah


class FooPlugin(GObject.Object, Sarah.IExtension):
    __gtype_name__ = 'FooPlugin'

    object = GObject.property(type=GObject.Object)

    def do_activate(self, args, argv):
        print("Foo", args)

    def do_deactivate(self):
        pass

btw there is already plugin for movies called watch check it in the plugins folder in this repo :)
