Convert c9 Revisions to Git Repo

Description

A simple app that converts document revisions stored in a 'c9' (or other compatible database) into a git repository.
'c9' here refers to the cloud9 IDE; see here for source reference.

Build Dependencies

Both of these will likely already be available as packages on your system.

• libgit2
• sqlite3

Note

If you choose to use this directly from the IDE, sqlite3.h is already available. To get libgit2 (at time of writing), you can run:

#> apt-get install libgit2-26
OR
#> apt-get install libgit2-dev

Clone and Compile

This can be done on a machine of your choice, or just on the 'c9' IDE. Open a terminal and:

$> cd [to a directory of your choice]
$> git clone https://github.com/bolt-blue/c9rev2git.git
$> make

Preparation

If working "locally", then first complete the following via the 'c9' IDE:

• There is a hidden directory with a lot of files, but likely only one that appears to be named as a SHA-1 hash (or at least some kind of hash).

  • Click the 'Settings' button in the file-tree view
  • Select 'Show Hidden Files'
  • Open '.c9', followed by the "hash-named" directory
  • Right click collab.v3.db and 'Save' to your system

• Alternatively, click 'File > Download Project' to create a full, local copy.

  • Then simply copy the target collab.v3.db to a working directory of your choice

Usage

This assumes you are running from the build directory. Provisions for actual installation on your system have not been considered here.

$> ./c9rev2git [-q] [-o output-dir] database.db

• -q Suppress informational output
• -o The name of the directory where the repo shall be created

Feature Todo

• Allow selective conversion (group several revisions into one commit)
• [Suggestions?]
