| |
|
| === Contributing to FreeMind ===
| | See [[Contributing]]. |
|
| |
|
| There are different possible ways of taking part in the FreeMind development: the project needs people for developing, testing and documenting of the program, and translating its interface and documentation in foreign languages.
| | ==Getting started as a developer== |
|
| |
|
| A new developer starts by sending his contributions for example as patches. Later on, he may get access to [[CVS]] repository. The process is approximately as follows.
| | See [[Getting started as a developer]]. |
|
| |
|
| * Create a user account at SourceForge.
| | ==Getting started as a tester== |
| * Discuss your contribution (the change, feature, bug fix, documentation or test plan) in our [http://sourceforge.net/forum/forum.php?forum_id=22101 open discussion forum].
| |
| * If the topic is accepted, start to change the actual CVS code. Be careful to use the right CVS branch. Currently we use the branch with a strange name "fm_060405_integration".
| |
| * For later merging of the code it could be better if you start from code state already labeled by a tag, e.g. "fm_0_9_0_beta9".
| |
| * If you have any questions during the implementing feel free to ask them in the "Open Discussion" forum. It is read by the other developers who possible can help you.
| |
| * Post your contribution in the patch section of SourceForge or send it by email to the current project manager. We do not respond immediately, as FreeMind team consists of volunteers.
| |
| * After having successfully developed and integrated some items, you get access to FreeMind's CVS repository at SourceForge.

|
| === Getting the latest beta version of FreeMind from CVS ===
| | See [[Getting started as a tester]]. |
|
| |
|
| A beta version you can get from the [[CVS]], searching there for the latest branch, or the branch of your choice. Please note that beta versions are unstable and may contain serious bugs. Please, use beta versions only if:
| | ==Reporting bugs== |
| # you urgently need a feature included in the version, and you are willing to backup your work often, or
| |
| # you want to give FreeMind developers feedback on the beta versions, which is highly appreciated.
| |
|
| |
|
| To get a beta version from CVS, see the guides at [[CVS]] section.
| | See [[Reporting bugs]]. |

| | Initially, every active developer of the core team works on his own GIT branch. Our intermediate results are |
| | | published as our "alpha versions". We use forum [http://sourceforge.net/forum/forum.php?forum_id=22101 Open Discussion] to communicate them. |
| Broken down into simple steps, a simple way for a developer of compiling FreeMind is perhaps the following.
| |
| | |
| # install [http://java.sun.com/javase/downloads/index.html Java SDK] — standard development kit
| |
| # install [http://ant.apache.org/ Ant] — a tool for building code using complicated make files)
| |
| # download FreeMind's [http://sourceforge.net/project/showfiles.php?group_id=7118 source code] as published in the Files section
| |
| # unpack the source code package with the extension <code>tar.gz</code>
| |
| # change directory to the one where <code>built.xml</code> file resides — the build file for Ant, similar to make files for the C language
| |
| # type <code>ant</code> in the command shell

| == Conceptual remarks ==
| |
| | |
| === Modular model - view design ===
| |
| | |
| The architecture of FreeMind makes it possible that FreeMind becomes general tool for editing tree-structured data, that is mind maps, XML/HTML documents, folder trees etc. in future.
| |
|
| |
|
| All these kinds of data would be presented to the user as a mind map. Model-View-Controller design makes it possible for you only to write so called model of the data structure, without caring for the visual representation. Currently, mind map mode and file mode are implemented.
| | Currently, there are no experimental versions available. The latest release candidate can be downloaded from [http://sourceforge.net/project/showfiles.php?group_id=7118 Files section]. |

| |
|
| === Original vision of Joerg Mueller === | | ==Obtaining focus for selected node in reliable manner== |
| | |
| Joerg Muller is the original author of FreeMind, developing it up to the version 0.4.0. Here follows what he's got to say on his original vision:
| |
| | |
| : What I had in mind when I began to write FreeMind, was creating a collaborative mind where people can intuitively share their ideas, knowledge and thoughts with each other. Of course FreeMind is only a first step into this direction, but I did this first step. Now a Mode must be implemented that makes collaboration over the Internet possible, maybe using the Topic-Map standard. I think linear text is a very poor way of representing knowledge, and by using trees and networks, visual representation, internet collaboration and open source we should be able to create some kind of a collaborative mind.
| |
| | |
| : FreeMind now has evolved from a specific Mind Map Editor to a generic editor for tree structured data. I want FreeMind to become for tree structured data what emacs is for linear data (ie. text).
| |
| | |
| One may think of extending FreeMind to work with networks as opposed to trees only, an example of this being Topic Maps (ISO).
| |
| | |
| Daniel Polansky: Joerg's vision of FreeMind becoming Emacs for tree data is intriguing, but rather far fetched at the time. You would need to provide scripting facility and at least many basic operations, like upcase, downcase, replace and many others. It is even not evident that this goal valuable compared to other goals - there many quite obvious and still missing features.
| |
| | |
| === Why not use OPML for storage instead of FreeMind's native XML format ===
| |
| | |
| The current version of [http://www.opml.org/ OPML] is not suited for our purposes. It should be easy to create conversion XSLT between FreeMind and OPML. First, if we decided to use OPML, we would have to wait until the owner of OPML changes his standard to fit our needs. Thus, we would be dependent, not being able to act dynamically. Second, already the current version of OPML is insufficient. It does not contain most of what FreeMind already uses: colors, fonts, folded tag, edges and icons. It is not a superset of FreeMind's XML format, even not in a vague sense. Even if I renamed the elements names properly, OPML would still be a subset and not superset of FreeMind's XML. As a result, we have no benefit from using OPML right now.
| |
| | |
| ''Summary:'' 1) we would run into dependence, and 2) OPML is insufficient, loosely speaking it is a subset.
| |
| | |
| === Why may FreeMind be more relevant than some other open source applications ===
| |
| | |
| There are many efforts to create new text editors, text processor and the like. While this activity is not without value, it does not fill that big value gap as mind mapping application.
| |
| | |
| Take, for instance, text editors like JEdit. There are already well estabilished text editors like Emacs or Vim, and there are many others. It's not that these editors would be perfect, far from that, but they're still pretty useful and with some training users can become very efficient with them.
| |
| | |
| With text processors, the thing is that most users in companies have already Microsoft Office for free. What does that mean? That means that the individual users do not have to pay for the MS Office, and they cannot effectively decide to use other Office platform either because of the value of easy sharing. Furthermore, there are competing free Office platforms like KOffice, OpenOffice or AbiWord.
| |
| | |
| In mind mapping, the situation is quite different. You do not get commercial alternative granted in companies, unlike office applications. The point here is that most of MS Windows users, the mainstream, do not have a mind mapping application yet. For them, starting to use FreeMind is not a switch from Microsoft product to alternative product. It is a switch from scattered documents in incomparable and hard-to-overview formats to one document with unprecedented order and transparency - FreeMind's mind map.
| |
| | |
| Therefore, I am expecting a growth of interest of free developers in developing and using this application.
| |
| | |
| Furthermore, even though Java is quite slow and memory hungry, it solves the neverending quarrel between religious die-hard fans of different computing platforms, which I have first experienced with Atari 800 XL versus Commodore 64 battle, later IBM compatible versus Commodore Amiga battle, and nowadays Windows versus Linux battles.

| == Misc ==
| |
| | |
| === To create a new release ===
| |
| | |
| To succesfully complete a new release, do the following
| |
| | |
| * upload the release files into /incoming at ftp:upload.sourceforge.net , use the user anonymous and your e-mail address as a password
| |
| * create new release. The files you have uploaded with ftp will be offered to you. Releases have names like "0.6.1", "0.6.5".
| |
| * update the home page so that it points to the new version of installation files
| |
| * post news, listing the most important changes of the new version
| |
| * repost the news to the Announce forum, with basically the same text
| |
| * repost the news the mailing list freemind-users@lists.sourceforge.net
| |
| | |
| Notice that the news cannot be monitored unlike forum, and forum has no RSS
| |
| feed unlike news.
| |
| | |
| === To create proper copyright notice ===
| |
| | |
| A source file may be viewed as a sum ''b'' + ''d<sub>1</sub>'' + ''d<sub>2</sub>'' + ... + ''d<sub>k</sub>'', where ''b'' is the basis, ''d<sub>i</sub>'' are deltas (or patches), and the plus operator is the operator of applying a patch. The basis and each delta have their own copyright holder and the year of copyright.
| |
| | |
| If there is only one autor and one year, then the copyright notice is simple.
| |
| | |
| If there is only one autor and more years, then the copyright notice may look like
| |
| | |
| <blockquote>
| |
| Copyright © 2003-2005 Big Author
| |
| </blockquote>
| |
| | |
| which is to be understood as
| |
| | |
| <blockquote>
| |
| Some parts of the sum are copyrighted in 2003, some perhaps in 2004, and some certainly in 2005.
| |
| </blockquote>
| |
| | |
| If there are more authors, then the copyright notice consists of more lines, like
| |
| | |
| <blockquote>
| |
| Copyright © 2003-2005 Big Author, <br>
| |
| Copyright © 2005 Captain,
| |
| </blockquote>
| |
| | |
| Not all changes are eligible for copyright. If a change is small, then it does not make sense to add a line to the copyright notice for it.
| |
| | |
| Copyright notice is not required for copyright to hold. It makes claiming your right at court easier.
| |
| | |
| The correctness of these instructions is not granted. They are subject to improvement as we see fit.

| === All on keyboard mappings ===
| |
| | |
| Currently, each function has at most one key assigned. But, it should be the other way around;
| |
| the keys should have functions assigned, rather than functions key. For instance, it would be
| |
| valuable to have both ''insert'' and ''tab'' assigned to ''new node'' function. (Actually on MS Windows it is right now not possible at all to bind anything to ''tab''.)

| === Libraries and tools used in FreeMind ===
| |
| | |
| * [http://nanoxml.cyberelf.be/ NanoXML]
| |
| | |
| === Sources of free icons ===
| |
| | |
| FreeMind uses (a) tool icons used in the toolbars, and (b) icons used in nodes. Especially for the icons used in nodes, a good comprehensive source of free icons is needed. FreeMind uses PNG icons, in the size of 16 x 16. Nowadays many icons are drawn in SVG vector format first, and converted to 16 x 16 bitmap images afterwards.
| |
| | |
| Ideally, it would not be the task of FreeMind team to draw icons; this task should be outsourced instead. Whether this is a realistic assumption remains to be seen.
| |
| | |
| Some links on the sources of free icons follow.

| == Implementation ==
| |
| | |
| === To obtain focus for selected node in reliable manner ===
| |
|
| |
|
| Requesting focus for NodeView using requestFocus() method is unreliable. A reliable way of doing that has been implemented in the method <code>obtainFocusForSelected()</code> of Controller. A typical call in ControllerAdaper.java is | | Requesting focus for NodeView using requestFocus() method is unreliable.

Line 44: |
|
| |
|
| where <code>newSelected</code> is a NodeView is unreliable, though most often works. | | where <code>newSelected</code> is a NodeView is unreliable, though most often works. |
|
| |
| === To set the class load path in manifest.mf in jar ===
| |
|
| |
| In the source folder tree of FreeMind, there's a file MANIFEST.MF. This file tells what
| |
| should happen with the freemind.jar when java tries to run the jar archive. The file
| |
| may look like
| |
|
| |
| Manifest-Version: 1.0
| |
| Main-Class: freemind.main.FreeMind
| |
| Class-Path: silk.jar nanoxml.jar ekit.jar kafenio.jar
| |
| kafenio-config.jar kafenio-icons.jar gnu-regexp-1.1.4.jar
| |
| Created-By: Joerg Mueller
| |
|
| |
| A tricky thing about the file is that the length of the lines can be
| |
| at most 72 characters. That creates difficulties when specifying Class-Path.
| |
| In the exaple above, the first line of Class-Path is set in such a way
| |
| that it has 70 chacters. That has been achieved by putting spaces before
| |
| the actual list of classes. In the freemind.jar, the file can be found in the
| |
| folder META-INF. Here you can check if the manifest has been created correctly.
| |
|
| |
| === Deleting nodes and branches in FreeMind ===
| |
|
| |
| Since version 0.8.0, it is possible to delete a whole branch of nodes by pressing DELETE. When a user accidentally presses DELETE and does not notice that, they may loose considerable amount of data. For users using FreeMind as a knowledge base or a semi-structured database, being able to delete whole branch at one keystroke is problematic and unusual; in filesystem browsers, users are asked for confirmation before the file is deleted by the system.
| |
|
| |
| However, some users use FreeMind as a mind mapper and are glad to be able to delete nodes just by pressing DELETE.
| |
|
| |
| There are several solutions to this problem.
| |
|
| |
| * Add user option to enable or disable confirmation before deleting of nodes and branches (depending on model type)
| |
| * Store all deleted nodes and branches in a kind of trashcan associated with every mind map
| |
| * Ask for confirmation only for nodes with children
| |
| * Ask for confirmation only for nodes with more than ''p'' children
| |
|
| |
| The confirmation would be requested both for keystrokes DELETE and CONTROL + X, that is the actions Delete and Cut.
