Hi All, |
| 2 |
|
| 3 |
My name is Kylepan and I'm working on Gentoo/Java integration Project. |
| 4 |
This is my first weekly report. |
| 5 |
|
| 6 |
Here is the brief introduction of my project: |
| 7 |
--------------------------------------------------------------------- |
| 8 |
The project includes an improvement to current java-config and a new |
| 9 |
eclipse-plugin. The plug-in, which when clicked, lists system installed |
| 10 |
java libraries for users to select and import into projects. This avoids |
| 11 |
user manually browses and locates system installed libraries, making |
| 12 |
developing more efficient and comfortable. The existing tool |
| 13 |
java-config, with some necessary improvements, is chosen as the data |
| 14 |
retrieval backend of this project. Jython is used to integrate |
| 15 |
java-config to the plug-in.This project will mainly benefit developers |
| 16 |
using eclipse, and due to planned work on improvements to java-config, |
| 17 |
it will benefit java-config project and even non-developer gentoo users |
| 18 |
as well. |
| 19 |

During the past few days I was devoting to the first step of my project |
| 22 |
--write a demo querying a variable of a java packge's package.env, whose |
| 23 |
function will be used in my project. And now the demo is completed and |
| 24 |
you can check in the |
| 25 |
repo(http://overlays.gentoo.org/svn/proj/java/projects/GenEclipse/trunk/) . |
| 26 |
It's an Eclipse project and should use my modified branch of |
| 27 |
java-config( |
| 28 |

|

|
| 31 |
issues: |
| 32 |
All issues are about compatibility and seem a bit annoying: |
| 33 |
|
| 34 |
As this project uses Jython to interpret python code, and the latest |
| 35 |
Jython implements Python 2.5 syntax. |
| 36 |
The snippet of code like: |
| 37 |
except UnexistingPackageError as e ( accepted in Python 2.6 and 3.1) |
| 38 |
complains in Python 2.5. |
| 39 |
while using: |
| 40 |
except UnexistingPackageError, e (accepted in Python 2.5 and 2.6) |
| 41 |
complains in Python 3.1 |
| 42 |
|
| 43 |
Since I have to use Jython , I have to use the later syntax, and it |
| 44 |
causes the errors in emerging my branch of java-config: |
| 45 |
|
| 46 |
-------------------- |

* Compilation and optimization of Python modules for CPython 2.6 ... |

| 55 |

!! ] |

* Updating desktop mime database ... |
| 61 |
---------------------- |
| 62 |
|
| 63 |
One solution I think is directly patch the src before |
| 64 |
"* Compilation and optimization of Python modules for CPython 3.1 ..." |
| 65 |
|
| 66 |
So I would like to ask suggestions that is it feasible and acceptable? |
| 67 |

Plans: |
| 70 |
My plans for next week: |
| 71 |
1. to solve that issue. |
| 72 |
2. to add the query javadoc function to java-config |
| 73 |
