SlickEdit

SlickEdit 9.0 is Microedge's $300.00 USD visual editor for Java (and dozens of other languages) that tidies source code. I use the older version 6.0c. I like it. I really like it. They now have a version that integrates with Eclipes. The support people are utterly amazing. I send in feature requests and they send me back SlickC code to implement the feature as a macro. I just wish it were cheaper so more people would enjoy it. It is worth far more than $300.00 USD in the time it will save you. Even though it is a very full featured editor, it comes up quickly. You can edit hundreds of files at once and hardly notice any slowdown. I use it to prepare all the HTML on this site and to write all my Java and assembler code. It has syntax highlighting and cross reference features that really speed things up. It will display help to fill in parms on any method. It will show you valid symbols for a given context. For HTML it has a IMG icon you can click that inserts the <IMG tag for a gif or jpg complete with correct height and width for you. The syntax highlighting and indenting beautifier makes your errors immediately obvious. I have been using it for years, and every day I discover yet new wonders it can do. It is the closest thing going to a SCID. Take time to configure your custom toolbars and custom keystrokes. You can even add your own icons to them. It supports several flavours of regular expression regex pattern matching search/replace.

Unfortunately it use the same extension vpj as Visual Café for its project files. You can download updates from support | patches on their website.

Make sure you regularly back up the binary file vslick/vslick.sta. It contains your complete configuration. If it goes, all your tools bars go to.

Customising

You can customise it to death if you have the patience to figure out how. For example, to control the file extension filters shown when you open a file for editing, edit the def_file_types parameter in the vusrdefs.e file, and then hit ESC and type vusrdefs to invoke the vuserdefs defmain batch macro. Later I discovered you could configure it from a menu Tools | Configuration | File Options | Filters.

I prefer to cut and paste, doing the editing of the file list string in the editor. Here is the one I use:

All Files (*.*),Java (*.java;*.jsp),HTML (*.html;*.css;*.htm),batch(*.bat;*.btm),Text (*.txt;*.list;*.csv;*.jnlp;*.log;*.mft;*.properties;*.site;*.use;*.wiki),Slick-C (*.sh;*.e),Assembler (*.asm),C++ (*.c;*.cxx;*.h;*.hpp;*.hxx;*.inl;*.cpp),SQL (*.sql)

You will probably want to configure tab to space conversion and trailing blank suppression while you are there.

Adding Custom Icons to Toolbars

The trick to adding a custom icon to the toolbar is to first drag a hammer icon from View | Toolbars | Categories | User Definable Tools to the menu bar. Then right click the icon and select Properties. Fill in Command, Message, Bitmap.

The command you associate with your new custom icon is whatever you would type on the command line at the bottom of the screen, not a bit of slickC code, e.g. you would fill in edit C:\env\todo.txt rather than edit('c:\env\todo.txt') or insert-java-main rather than insert_java_main().

A good place to find a the names of built in commands you can use on the command line is in Tools | Configuration | Key Bindings even if you don't want to bind a key. Not all SlickC functions work on the command line.

The toolbars are locked from inadvertent changes except when the View ToolBars dialog is active. Then you can rearrange the icons, or drag them off the tool bar to remove them.

The Message is just the toolip text.

You create your own bitmap icons as BMP files and use them just like the builtin ones on toolbars. Use grey 192,192,192 as your background. BMP files don't have a formal transparent background the way GIFs do. Make them all 23x21. Make sure you have backup copies of the bitmaps outside the vslick\bitmaps directory which you may lose on reinstall. Also make a record of the bitmap names, command, and tooltip text so you can reconstruct it if you lose the menu bar.

Here is a little script you can save in a *.e file, then load to create a new command called cdm which changes the directory then brings up the open file dialog box on that directory. To install the command, load the *.e file, with load macro, and it will stay installed forever, (or at least until you unload it.) You can then create an associated icon on the toolbar for one click open. You can define several such commands in a single *.e file.

#include "slick.sh"
_command cdm()

{
cd('E:\mindprod\');
gui_open();
}

SlickC Macro Language

You program it in SlickC which bears only a superficial ressemblance to C/C++. SlickC has no classes. It has safer pointers than C. It uses containers, decimal arithmetic and both typed and untyped variables like Rexx, It works like Visual Basic for its dialog boxes. It has Java-like ArrayList style autogrowing arrays, and hashtables that masquerade as arrays. The syntax is, to put it kindly, eclectic, held together with duct tape and bailing wire. The designer has never heard of the concept of orthogonality. Every feature of the language comes with a list of odd exceptional conditions under which it does not work. It is the quirkiest most ad hoc, asymmetrical language I have ever encountered, and probably the hardest to learn. However, the pcode it uses is fast and compact and gets the job done. All the common methods are written in native code for speed. You must You learn it mainly by studying the existing source code. I would assume most people using it never learn any SlickC, but even then it is still a powerful editor.

SlickC macro language usevs some very strange language constructs and odd terminology. defmain and batch macro refer to a type of nameless procedure. All you can do is load it and execute it once. Usually it defines the the values for many configuration constants. procedure is much like a Java method, except that it usually takes a variable number of parameters, and the types of the parameters are deduced dynamically by the procedure. command is a procedure that can be bound to a keystroke, with rules about the contexts in which it is valid to call it.

Macros you create by recording keystrokes are stored in vslick/macros/vusrmacs.e. They generate compilable SlickC code.

Here is a simple macro to generate the boilerplate for a Java main method:

// stored as C:\env\javamain.e

#include "slick.sh"

/**
* Define conditions under which the insert_java_main
* command will work.
*
* @param cmdui
* @param target_wid
* @param command
* @return enabled or disabled.
*/
int _OnUpdate_insert_java_main(CMDUI cmdui,int target_wid,_str command)
{
if ( !target_wid || !target_wid._isEditorCtl()) {
return(MF_GRAYED);
}

return((target_wid.p_extension=='java')?MF_ENABLED:MF_GRAYED);
}

/**
* Generate a java main method by typing insert_java_main on the command line.
* Command can also be hooked to a button, or to a keystroke.
*
* @return
*/
_command insert_java_main() name_info(','VSARG2_MARK|VSARG2_REQUIRES_EDITORCTL)
{
if ( p_extension!='java' ) {
// Check to see if we are in java mode. If not, exit
message( nls( 'Command not allowed while not in java mode' ) );
return('');
}
insert_line( '/**' );
insert_line( ' * test harness' );
insert_line( ' *' );
insert_line( ' * @param args not used' );
insert_line( ' */' );
insert_line( 'public static void main ( String[] args )' );
insert_line( ' {' );
insert_line( ' }' );
}
