Development/FAQs/General FAQ


新しいアプリケーションを書き始めたいのですが、何かアドバイスはありますか?

新たに書かなければいけない KDE アプリケーションがたくさんあるのは間違いありません。しかし、 あなたの助けを必要とする既存の KDE アプリケーションがたくさんあるのも確かです。

どの分野に助けが必要か知るには、このページをチェックしてください。

新しいアプリケーションを書き始める前に、KDE-Apps.org をチェックしたり、[email protected] のメーリングリストで聞くなどして、誰かが似たようなプロジェクトをしていないかどうか確かるのは良いことです。

私は開発者です。どうすれば KDE に貢献できますか?

KOffice や KDevelop は高く評価されているにもかかわらず、開発者がとても少ないので、そのあたりをチェックすると良いかも知れません。KDE のプロジェクトを手助けするのに、KDE のコアの開発者になる必要はありません。KDE は非常にうまくモジュール化されているので、全体のシステムがどうなっているか知らなくても、1つの分野を改良することができます。

また、kde-devel メーリングリストで、誰かがアプリケーション上での手助けを必要としているか質問することができます。 最新の KDE を使い必要とされていることを見付けて下さい。テーマジェネレーター? Konsole のスキーマエディタ? ゲームの改良? ちょっとした機能不足は常にあるものです。実装してしまいましょう!

特定の分野に関してくわしかったり、興味があったりしますか? あなたの手助けが役に立つその分野に関連するアプリケーションがないかチェックして下さい。もしくはそのようなアプリを書いて下さい。KDE には、もっと一般ユーザー向けのアプリケーションが必要です。

私は開発者ではありません。どうすればお手伝いできますか?

開発者のスキルを必要としない仕事がたくさんあります。アプリケーションのレビューの執筆による KDE の宣伝 (kde-promo メーリングリストを参照)、ドキュメント作成 (i18n.kde.org/doc 参照)、翻訳 (i18n.kde.org 参照)、新規バグのフィルタリング (bugs.kde.org 参照) などです。

Konqui the dragon の画像はどこで手に入れることができますか?

The Konqi for some people SDK is at ftp.kde.org/pub/kde/devel/konqi_sdk.tar.bz2
It was posted to artist.kde.org before that site ceased to be updated.

Further images are on KDE merchandise.

KDE に貢献するのに必要なスキルのレベルはどの程度ですか? 何を学んでおくべきですか? 何を読んでおくべきですか?

C++ について知っている必要があります。Qt で何が可能か知るためにQt チュートリアルを読み、 Qt ドキュメントを拾い読みしてください。そして、KDE チュートリアルを読んで、アーキテクチャやドキュメントを斜め読みしてください。また KDE Book を読んでも良いかも知れません。損にはならないはずです。しかし、KDE の開発者になるのに、KDE 全体のアーキテクチャについて詳しくなる必要はありません。KDE のテクノロジーを利用することはとても簡単なので、本当にあなたが必要とするところだけに集中してください。他の部分については後で学べます。 KDE TechBasedoc.qt.nokia.com ($QTDIR/doc/html にもあります) は計り知れない程の情報源です。これらを利用してください。 その後、ソースを読んで、examples ディレクトリを探して、他人がそれらのアプリケーションをどのようにコーディングしているか見て下さい。コードを読み、書くことはいちばん良い学習方法です。

KDE の git や SVN のリポジトリーから KDE ソフトウェアを取得するにはどうすれば良いですか?

Getting_Started ページの "Building and Running KDE Software From Source" (ソースから KDE ソフトウェアをビルドして実行する) セクションを確認して下さい。

KDE のソースコードに Web ブラウザからアクセスすることは出来ますか?

はい。

などの方法があります。

.subversion/config にはどのように記述すべきでしょう?

[miscellany]
global-ignores = *.moc *.moc.cc *.moc.cpp config.log config.status \
config.cache *.gmo .deps .libs SunWS_cache *.lo *.la *.rpo *.la.closure \
*_la_closure.cpp *_la_closure.cc *_la_closure.cxx *.all_cc.cc *.all_cpp.cpp \
*.all_C.C *.all_cxx.cxx *_meta_unload.cc *_meta_unload.h *_meta_unload.cpp \
*_meta_unload.C *_meta_unload.cxx index.cache.bz2 .memdump Makefile.rules.in \
Makefile.calls.in Makefile.rules Makefile.calls autom4te.cache *.kidl \
*.o *.lo *.la #*# .*.rej *.rej *.pyc

それから、svn diff にスペースを無視させ、また、関数名を表示させるために、

[helpers]
diff-cmd = /usr/local/bin/_svndiff

と記述します。

そして /usr/local/bin/_svndiff に、

#!/bin/sh
exec /usr/bin/diff -b -u -p "$@"

と付け加えます。

Don't forget to make /usr/local/bin/_svndiff executable.

I want to put my app in KDE

There are three requirements:

  • your app must compile with the latest version of KDE (git master or SVN trunk).
  • your app must be stable.
  • your app must be maintained. You will probably get a good deal of bug reports and wishes. People expect you to fix the bugs and implement the wishes that make sense.

See also the next question.

Is it better to develop inside or outside KDE?

As core developer Waldo Bastian explains in a copyrighted mail:

Being part of KDE means that you have to work together with others. Such cooperation brings along advantages but it also brings along responsibilities.

Some of those advantages are: your code ends up on all distro's, people might fix your bugs, you get free translations and documentation, you get tons of bugreports.

On the other side there are disadvantages and responsibilities: you will have to communicate with other developers about your work, other people might make changes to your code, you will have to respect release freezes, you get tons of bugreports and people actually expect that you fix them as well (what are they smoking?), people expect you to maintain your code.

You can't chose for the advantages and ignore the responsibilities that come with it, it's a complete package, it's both or nothing.

In general it should be the author of a piece of software that chooses to put his application in KDE's repositories. We usually don't put software in KDE's repositories unless the author wishes to do so. The other way around, if the author prefers to work on his application elsewhere then that's his right as well. Unless there is a split in the actual group of people working on the application it makes no sense to fork the development of an application because of that.

BUT... by putting your code under and open source license and putting it in a KDE repository you give the world at large, as well as KDE in particular, the irrevocable right to use your code. And KDE will use that right at its discretion to protect the interests of KDE, even if that goes against the wishes of the author at that point in time.

It is important to know that but don't be afraid. Usually, things work very well. In 5 years, it has only happened once that a developer had his work put kept in KDE while he wanted to remove it.

How do I get write access to KDE repositories?

See full article at Contribute > Get a KDE Contributor Account.

Go to [KDE Identity] , fill out the form and describe why you need write access. Make sure to specify your full name and e-mail address.

Please also include the name of your bugs.kde.org account, if non-existent please create one so that it can be given usual developer rights. Closing bugs.kde.org reports with keywords in commit comments only works if the email address of your KDE Identity and bugs.kde.org accounts match. You can change your bugs.kde.org address in the Bugzilla user settings.

Git requires use of an ssh key, and new accounts for SVN must also choose the svn+ssh protocol. Send a public ssh key (e.g. ~/.ssh/id_dsa.pub)

See also #How do I create a SSH key?

If you are contributing to an application that is not yours, it is a good idea to first submitting your coding as patches to the author and let him apply them. If the author is not maintaining his application, you might become the new maintainer...

Although there are few restrictions on repository commit rights, we expect you not to disrupt other developers' code without their consent. You must also respect the feature freezes of the release schedule (published on developer.kde.org)

A detailed list of rules you should follow when committing to KDE repositories are listed in the KDE Commit Policy.

My app is not stable but I would like to have it in KDE

As a first step, we can put it in playground, which is essentially "kde-alpha". Develop it there and when it is ready, request that your app to be moved to the appropriate KDE package or the extragear module.

I don't want to lose my SVN history.

This is no longer possible with Subversion. Maybe in the future, if the server is upgraded and allows that. Note that for git this is not an issue.

What is kdebindings?

It contains Qt bindings for Ruby, PHP, C# to use Qt classes with those langages, KDE bindings for Ruby, C#, python to use KDE classes with those langages, and XParts to embed non-KDE apps as a KPart. Check the binding page of TechBase.

Does the feature freeze apply to playground?

No, playground are not a released packages. The same is true for kdereview and extragear: they are not frozen and released. But if you want your app to move to a package, ask for it before the beta-release.

Can I have a stable and an unstable KDE on the same computer?

Yes, check the Building 2 Versions documentation.

How do I know which version of Qt/KDE I am using?

kde-config and all kde programs accept --version as argument.

Qt-copy or Qt from qt.nokia.com : if one were doing a clean build of trunk, which would be preferable?

You can use either. They are binary compatible (forward and backward). There can be, however, a few bugfixes in qt-copy over the most recent Qt release. Especially if building from qt-copy, pay attention to the apply-patches script.

How can I checkout a single directory from a SVN module?

Checkout the top-level dir with 'svn co -N /modulename', 'cd modulename', 'svn up admin' to get the admin/ dir and then finally checkout the dir you want with 'svn up subdir'

For instance, to get only reaktivate from playground/utils: svn co -N /playground/utils; svn up reaktivate Then compile as usual.

The same answer applies to the question "How do I get a single language out of kde-i18n?".

If you don't know the name of the directory you want to check out, you can browse websvn.kde.org to find it.

How can I get one of the KDE application as a standalone tarball?

kdesdk/scripts/svn2dist is a script to extract an application from the KDE source tree and package it as a standalone application.

How do I close my own bug reports?

If you reported a bug that is fixed in a new release of KDE but is still reported as open, you can close it. It might happen because your bug is the same as another one, or simply because the developer fixed something without noticing that it would correct your bug.

You can do that from your Subversion commit. To do so, append to your commit message a line like this:

BUG: XXXXX where XXXXX is the bug report you want to close. If the report you're closing is adding a new feature, you can use FEATURE instead of BUG.

Managing a bug list is a huge task for the developers and they usually have a lot of bugs listed, some being fixed already without their knowledge, some being unreproducible, some without enough information to be corrected, etc. If you can help by managing and updating the list of outstanding bugs, you will be gladly welcome. And you will receive an even happier welcome if you provide a patch.

How do I create a SSH key?

SSH makes use of two keys: a private key and a public key. You should keep the private key secret at all times and only place it on machines over which you have direct control. Public, shared, and community machines are not suitable environments to store SSH private keys. Take action to help prevent theft of your SSH private key data. Setting a password on your SSH private key will help reduce the risks involved with private key theft.

Generate a key pair for each major location you work from. This helps to reduce the impact when your key gets stolen. When someone obtains access to your private key, your key can be abused in attempts to compromise KDE servers. Well known open source projects have been compromised this way in the past, YOU must help us to make sure that this doesn't happen with KDE servers as well. For that reason it is important to notify sysadmin (at) kde (dot) org immediately when you notice that someone may have had access to your private key for example when a computer on which it was stored has been hacked or infected with a virus, worm or trojan.

If you choose to make a backup of your SSH private key data, please ensure that any such backup is stored in a secure manner as well.

For the practical part, the following command can be used to generate a SSH private/public key pair with ssh-keygen -t dsa This will create a private key as ~/.ssh/id_dsa and a public key as ~/.ssh/id_dsa.pub.

There are times when you may want to use a key of a different name to the default, perhaps to use separate keys for different projects. To let SSH know which key you want to use for KDE.org, you can keep a list of servers and their corresponding keys in ~/.ssh/config. For example,

Host svn.kde.org 
IdentityFile ~/.ssh/id_dsa_kde

In order to use SSH to access KDE servers you need to send your public key to sysadmin (at) kde (dot) org.

How can I monitor changes made by others?

The kde-commits mailinglist carries automatic notifications for all changes made in the KDE repositories. The KDE-Commits mailinglist is very high traffic. An alternative is CommitFilter which allows you to get notification for only those areas that interest you.
