It's a chao not to track bugs and feature requests when you developing software. Having a simple issue tracker would make managing the project much more successful. Now I like simple stuff, and I think for small project, having this tracker right inside the source control (especially with DSVC like Mercurial/Git etc) repository is not only doable, but very convenient as well. You don't have to go crazy with all the fancy features, but just enough to track issues are fine. I would like to propose this layout for you.
Let's say you have a project that looks like this
project +- src/main/java/Hello.java +- issues/issue-001.md +- pom.xml
All I need is a simple directory issues to get going. Now I have a place to track my issue! First issue issue-000.md should be what your project is about. For example:
/id=issue-001 /createdon=2012-12-16 18:07:08 /type=bug /status=new /resolution=open /from=zemian /to= /found=v1.0.0 /fixed= /subject=A simple Java Hello program # Updated on 2012-12-16 18:07:08 We want to create a Maven based Hello world program. It should print "Hello World."
I choose .md as file extension for intending to write
comments in Markdown format. Since it's a text file, you do what you
want. To be more structured, I have added some headers metadata for
issue tracking. Let's define some here. I would propose to use these and
formatting:
/id=issue- /createdon= /type=feature|bug|question /status=new|reviewing|working|testing|fixed /resolution=open|closed|rejected|hold /from= /to= /found= /fixed=
That should cover most of the bug and feature development issues.
It's not cool to write software without a history of changes, including
these issues created. So let's use a source control. I highly recommend
you to use Mercurial hg. You can create and initialize a new repository like this.
bash> cd project bash> hg init bash> hg add bash> hg commit -m "My hello world project"
Now your project is created and we have a place to track your issues.
Now it's simple text file, so use your favorite text editor and edit
away. However, creating new issue with those header tags is boring. It
will be nice to have a script that manage it a little. I have a Groovy
script issue.groovy (see at the end of this article) that let you run reports and create new issues. You can add this script into your project/issues directory and you can instantly creating new issue and querying reports! Here is an example output on my PC:
bash> cd project bash> groovy scripts/issue.groovy Searching for issues with /resolution=open Issue: /id=issue-001 /status=new /subject=A simple Java Hello program 1 issues found. bash> groovy scripts/issue.groovy --new /type=feature /subject='Add a unit test.' project\issues\issue-002.md created. /id=issue-002 /createdon=2012-12-16 19:10:00 /type=feature /status=new /resolution=open /from=zemian /to= /found=v1.0.0 /fixed= /subject=Add a unit test. bash> groovy scripts/issue.groovy Searching for issues with /resolution=open Issue: /id=issue-000 /status=new /subject=A simple Java Hello program Issue: /id=issue-002 /status=new /subject=Add a unit test. 2 issues found. bash> groovy scripts/issue.groovy --details /id=002 Searching for issues with /id=002 Issue: /id=issue-002 /createdon=2012-12-16 19:10:00 /found=v1.0.0, /from=zemian, /resolution=open, /status=new /type=feature /subject=Add a unit test. 1 issues found. bash> groovy scripts/issue.groovy --update /id=001 /status=fixed /resolution=closed 'I fixed this thang.' Updating issue /id=issue-001 Updating /status=fixed Updating /resolution=closed Update issue-001 completed.
The script give you some quick and consistent way to create/update/search issues. But they are just plain text files! You can just as well fire up your favorite text editor and change any any thing you want. Save and even commit it into your source repository. All will not lost.
I hope this issue tracking script can get your next project started quickly. Let me know what you do you think!
Enjoy!

Here is my issue.groovy script.
#!/usr/bin/env groovy
//
// A groovy script to manage issue files and its metadata/headers.
// Created by Zemian Deng <saltnlight5@gmail.com> 12/2012

// Usage:
// bash> groovy [java_opts] issue.groovy [option] [/header_name=value...] [arguments]
//
// Examples:
// # Report all issues that match headers (we support RegEx!)
// bash> groovy issue /resolution=open
// bash> groovy issue /subject='Improve UI|service'
// bash> groovy issue --details /status=fixed
//
// # Create a new bug issue file.
// bash> groovy issue --new /type=bug /to=zemian /found=v1.0.1 /subject='I found some problem.' 'More details here.'
