Release Notes

1.0.12

• Changed default value of option SourceView.showAttributes to on.
• A command creating a mphantom element has been added to the trivial and ucd insert modes.
• Added commands in the content insert mode for elements bind and bvar. Furthermore, a command that creates a lambda expression (fns1#lambda) has been added.
• Performance of NTNView: Do not rerender with JOMDoc if only the cursor has been moved.
• Performance improvement: If Gemse can not keep up with the user, the views are no longer reconstructed after every single command.
• New command :goto: It jumps to the equation with the given number.
• The OthersView now shows numbers along the equations. Like this, one can see empty equations and the number can be used with the command :goto.
• Gemse can now be called from the command line: Use the flag -gemse to start Gemse with an empty equation. -gemse-load URI opens Gemse and loads URI as equation. -gemse-do COMMANDS opens Gemse and executes the given commands. If there is already running an instance of Gemse, then no new instance is started but the running one is informed which then does what is requested.
• The backspace character is now shown in a human friendly way (using U+232B ⌫) in the documentation.
• Now, if an error is thrown, the input buffer is cleared. This prevents unexpected stuff from happening when the user types new commands after an error occured.
• A new equation no longer has an id attribute on its math element.
• SourceView no longer shows attributes whose names begin with a dash. Such attribute names are not well formed XML and are only used internally by the MathML rendering code of Mozilla. They should not be visible in the DOM but they are anyway because of a bug in Mozilla.

1.0.11

• Files in the java directory no longer need to have specific names.
• Viewsets now have names.
• :help installation-directory&enter; reveals the location where Gemse is installed.
• The new command :example loads examples shipped with Gemse.
• NTNView works with (and requires) at least JOMDoc 0.1.4.
• NTNView shows the cursor. (Thanks to Christoph Lange for giving me a hint how to implement it.)
• The OthersView, that shows all open equations, now allows to switch to another equations with a mouse click in certain situations.
• If more than one message is issued at once, all of them are now shown to the user. As soon as the user enters another command, all messages are removed.
• Loading and saving has been completely redesigned.
• A lot of documentation has been written and updated.

1.0.10

• Fixed the trivial insert mode
• Added a the killPrevious command to all insert modes. It removes the last inserted element. It is by default bound to the backspace key. As a result, you no longer need to exit the insert mode just because you hit a wrong command.
• Insert modes are now allowed to change any element, not only the descendants of the element the cursor was contained in when the insert mode was called.
• Increased the maximal version of XULRunner to 1.9.* and of Firefox to 3.6.*
• Added the NTNView which uses JOMDoc to render Content MathML as Presentation MathML in real-time. It is part of viewset 5. In order to use it, you have to download JOMDoc and drop it somewhere in Gemse's installation directory. You find more information about that in the documentation about the views.
• Gemse is now licenced under the GNU GPL3 or later.

1.0.9

• A system for handling options has been introduced.
• Some options have been added and documented. The tutorial contains a section about options as well.
• Errors are now reported to the user inside a view. Before, they have only been reported in the error console, leaving the user in the dark.
• The source view has been reimplemented. It has some options which can be used to adapt its behaviour. They are documented in the options page of the help and some of them are discussed in the tutorial.
• The register * can now be used to copy to/from the system clipboard.

1.0.8

• When loading an equation at startup, the unnecessairy empty equation is no longer created.
• New commands for saving and closing have been added. They make it easier to deal with multiple equations. The most useful are ZZ and ZA.
• The command unwrap has been added. It removes an element and puts its children at its old place.
• The input box no longer moves below the window. A scrollbar is added, if the views use more space than available.
• A bug in the input substitution has been corrected: It was not possible to use entites whose value contain some special character (>, & and so on), since they were decoded only once but this has to be done twice.
• The EquationView has been added. It shows the rendered equation with some visual additions. Most notably, it transforms Content MathML to Presentation MathML. Viewset 4 uses this new view.

1.0.7

• Added the content insert mode which allows one to write Content MathML
• Added an edit mode command to follow an xref.
• The command of the edit mode that creates an mrow around the selection now creates an apply element instead, if the first element of the selection is a Content MathML element.
• Implemented better strategy for updating views.

1.0.6

• The user interface changed drastically: Views and viewsets have been introduced. As a side effect, the XHTML interface has been replaced by a XUL interface. Now editor.xul has to be used instead of editor.xhtml.
• The tutorial has been updated.
• The equation turning up when starting Gemse is now the empty one. The old one can be loaded from doc/example02.xml.
• Element descriptions in elementDescriptors.js have been updated. They now correspond to the Presentation MathML part of the working draft http://www.w3.org/TR/2009/WD-MathML3-20090604/.
• Updated documentation on how to install and run Gemse.

1.0.5

• Gemse is now available as Firefox extension, XUL application and as a Minimal edition for use outside of the Firefox chrome. Of course a source package which contains a script which creates the packages is also available.
• Some documentation for developers has been added, which introduces the basic ideas of Gemse. Most of it has still to be written. However, detailed documentation can be found in the sourcecode itself and can be extracted using the JsDoc toolkit.
• The stylesheet is now structured more readable and contains comments.
• When more than one equations are open, only the one you are currently editing is shown in full size. This behaviour can be changed by editing the stylesheet.

1.0.4

• The UCD insert mode now treats combining characters in a special way.
• The processing of commands has been completely revised. A new class CommandHandler is used by the modes to process commands. This saves a lot of code replication and all features are available to all modes. The modes can further process input if no command have been found or if an error occured. As a side effect, the documentation of the commands has changed.
• The default insert mode is now the UCD insert mode. The insert mode can be changed by pressing the tabulator key while in edit mode.
• The default register is now called ". Change and delete commands now put a copy of the removed elements into the default register. Copy commands also put a second copy the the yanked elements onto the default register. So the behaviour now equals vim's behaviour in this regard.
• A lot of documentation in the source code has been added. The code has been improved in many places.
• More commands and bugfixes.

1.0.3

• An operator dictionary has been added. Up to now, it is only used by the attribute mode. There you can set attributes according to a dictionary entry. The dictoinary is based on the operator dictionary provided by the MathML 2 specification.
• The input substitution has been changed fundamentally. The sequences that get substituted look now like XML entities. One can insert characters by their codepoint: For example α gets substituted with α. Characters can also be inserted by name: For example α gives α as well. The names are taken from the w3c's collection of entities. In this release, input substitution is on by default.
• A new UCD-based input mode has been added. UCD-based means that the mode queries the unicode character database to find out whether a character is an operator, an identifier or a digit. This means that you do not need to hit o before an operator or i before an identifier. The old input mode is the default, you can change this by hitting the tab key.
• Unicode characters that do not reside in the BMP (for example 𝕂), can now be used everywhere: As name of commands in all modes, as names of registers and as operators or identifiers in the insert modes. The problematic part about that is that JavaScript stores unicode characters with 16 bits per character. Since characters outside the BMP can not be represented by 16 bits, a pair of surrogate characters is used, that is, they are represented by two characters. So everywhere Gemse expects one character, it has to check whether it is a surrogate and in this case has to take two characters!
• The command :export has been added to the edit mode. It allows you to translate your equation into LaTeX. At the moment, however, you need to download the additional library that is needed for this feature yourself. More information you can find in the documentation of this command.

1.0.2

The surround feature has been added to the insert mode. It allows you for examlpe to first write the base of a potency and then hit ^ later on.

Sometimes it happened that inserting a wrong command screwed up the whole editor since it was no longer possible to clear the input box. Now clearing the input box using &esc; should always work.

Some commands have been added and the documentation has been improved.

1.0.1

Many commands have been added. The insert mode supports more elements. More documentation, including a short introcution to Presentation MathML has been added. This is still a development release tought to get feedback from users.

1.0.0

This first release shows the idea behind Gemse. It is still missing many features. It is not a production release but thought for collecting feedback from potential users.
