Time flies by…!! 
All the summer is now over, monsoon has arrived 
and my college has started 
and
I have reached the final week of my GSoC-2018 work period.
The last week, I completed pendging modules’ tests, I got most of my pull requests merged and I started working on writing tests and documentation. Two basic example scripts of adding files to index and cloning can be viewed on the project repository.
The lua bindings bindings for a total of 32 modules has been written and of which 28 modules have their tests
completed.
These modules are merged to the master as of now, few are remaining to be added.
libgit2, cred, config, oid, signature, clone, repository, tree, commit, index, reference, branch, blame, blob, tag, object, buf, revwalk, annotated, checkout, reset, describe, reflog, revert, revparse, diff
As an example script to add files to current index,
------------------------------------------------------------------------------
--
-- luagit2's "add" example

-- shows how to modify the index
--
-- The user should pass a valid git repository's path as 1st argument.
-- and can pass as many file path to add to the current index as he/she wishes.
--
-- Note : the passed file paths must be relative to the given repository's path
--
local luagit2 = require("luagit2")
----------------------------------------------------------
-- The necessary funation call for initializing
-- Libgit2's global state & threading
----------------------------------------------------------
luagit2.init()
----------------------------------------------------------
--
-- Get the params from comand line
----------------------------------------------------------
local repo_path = arg[1]
local num_files = (#arg)
----------------------------------------------------------
--
-- Open repo using passed repository's path
----------------------------------------------------------
local repo = luagit2.repository_open(repo_path)
----------------------------------------------------------
--
-- Get the repository's current index
----------------------------------------------------------
local repo_index = luagit2.repository_index(repo)
----------------------------------------------------------
--
-- Add the files to current index
----------------------------------------------------------
for i=2,num_files do
luagit2.index_add_bypath(repo_index,arg[i])
end
----------------------------------------------------------
-- Finally write the added files onto the disk
----------------------------------------------------------
luagit2.index_write(repo_index)
----------------------------------------------------------
--
-- must free the used repository and index to prevent
-- memory leaks
----------------------------------------------------------
luagit2.index_free(repo_index)
luagit2.repository_free(repo)
----------------------------------------------------------
--
-- Shutdown the libgit2's threading and global state
----------------------------------------------------------
luagit2.shutdown()
The final implementation to do cool git things using luagit2 requires comparitively less number of lines. Yey!
I am trying to add variant examples, targeting maximum example usage of luagit2 for users.
Also for a better understanding, one may wish to go through the tests for the time documentation has been completed.
To Do
These are some of the further todo on luagit2 project according to me.
- Implement the garbage collecter logic so that user may not need to free the used variables.
- Setup Travis CI and other similar CI checks for luagit2.
- Write lua bindings for submodule & remote module.
- Convert luagit2 for lua5.1. Very basic and minor task.
