Adie is an extremely fast and convenient programming text editor written using the FOX Toolkit.
Besides being a nice text editor, Adie is also an extremely convenient file viewer, supporting a plethora of methods to move from one file to the next.
For each visited file, Adie remembers where in that file you were last looking, and which special places in that file have been bookmarked, so you can quickly return to frequently visited places.
Project browsing is made easy by optionally displaying a File/Directory browser side by side with the text so files may be visited by means of a single click. Files may also be opened simply by highlighting a file name, compiler warning message, or #include directive and hitting a single button; Adie will search for the file in the same directory as an already loaded file, or in a number of predefined directories (like for example include directories).

• Programmable syntax coloring and text styles.

To start a new document, invoke the New menu, or press on the New button on the toolbar. If the current document has not yet been saved, you will be prompted to either save or abandon the current text.

To open a file, you can invoke the Open menu, or press on the Open button on the toolbar. This will bring up the standard File Dialog, which allows you to select a file.
To save a file, you can either invoke the Save or the Save As menu option. The former saves the file back to the same filename, while the latter prompts for an alternative filename.
You can quickly navigate to the desired file by typing the first few letters of the filename and then pressing Enter (Return); use Backspace to move up one directory level. Control-H moves to your home directory, Control-W moves back to the current working directory.
A nice convenience of the File Dialog is the ability to set bookmarks, so once bookmarked, you can quickly move back to a previously visited directory.

An alternative method to open files is the File/Directory Browser. You can display the File/Directory Browser by invoking the File Browser option under the View menu. To open a file using the File/Directory Browser, simply click on the file. If there are many files, you may want to limit the number of files displayed by specifying a file pattern in the Filter typein field.
The pattern is can be any regular file wildcard expression such as "*.cpp". By default, the File/Directory Browser shows all files, i.e. the pattern is "*".
You can switch patterns by means of the combo box under file File Browser; additional patterns for the combo box (and File Dialog) can be specified in the Preferences Dialog.

The recent file menu shows files which have been recently visited. You can quickly get back to a file you've been editing simply by selecting one of these recent files.

Using a file browser such as PathFinder or other Konqueror or other XDND compatible file browsers, you can simply drop a file into the text pane and have Adie read this file.
Of course, the File/Directory browser supports drag and drop also, so you can also drag a file from the File/Directory browser into the Text Window.

Selecting any filename, possibly in another application, and invoking the "Open Selected" option causes Adie to open the selected file. When the selected filename is of the form:

#include "filname.h"

or:

#include <filename.h>

then Adie will search for this file in a sequence of include directories, otherwise it will search in the same directory as the currently loaded file. You can specify the list of include directories to search with the "Include Path" option. When the selected filename is of the form:

filename.cpp:177

then Adie will not only load the filename, but also jump to the given line number. If this file has already been loaded, Adie will simply jump to the given line number in the current file. This option is very useful when fixing compiler errors.

You can move the cursor by simply clicking on the desired location with the left mouse button. To highlight some text, press the mouse and drag the mouse while holding the left button. To select text a word at a time, you can double-click and drag; to select text a line at a time, you can triple-click and drag.
Performing a shift-click extends the selection from the last cursor location to the current one.
When selecting words, words are considered to extend from the clicked position up to a blank or word-delimiting character. The latter may depend on the programming language, and so Adie offers a way to change the set of delimiter characters.

Using the right mouse button, you can grab the text and scroll it. a right mouse drag is a very convenient way to scroll the text buffer by small amount as the scrolling is exactly proportional to the mouse movement.
You can of course also use the scroll bars. Because scrolling becomes awkward when dealing with large amounts of text, you can do a fine scroll or vernier-scroll by holding the shift or control keys while moving the scroll bars.
Adie can also take advantage of a wheel mouse; simply point the mouse inside the text area and use the wheel to scroll it up and down. Holding the Control-key while operating the wheel makes the scrolling go faster, by smoothly scrolling one page at a time. To scroll horizontally, simply point the mouse at the horizontal scroll bar.
In fact, any scrollable control (including the File/Directory Browser), can be scrolled by simply pointing the cursor over it and using the mouse wheel.
You can adjust the number of lines scrolled for each wheel notch by means of the Preferences dialog.

After selecting some text, you can cut or copy this text to the clipboard. A subsequent paste operation will then insert the contents of the clipboard at the current cursor location.
If some text has been selected in another application, then you can paste this text by placing the cursor at the right spot in your text and invoking the paste command.

When text is selected anywhere (possibly in another application), Adie can paste this text into the current text buffer by means of the middle mouse button or by pressing the wheel-button if you have a wheel mouse. Note that while holding the button, the insertion point can be moved by moving the mouse:- Adie will only insert the text when you release the button.

After selecting some text, you can drag this text to another location by pressing the middle mouse button; because Adie is fully drag and drop enabled, you can not only drag a selection from one place to another inside the text buffer, but also between different Adie applications, or even from Adie to another drag and drop enabled application or vice-versa.
Within the same text window, the drag defaults to a text-movement. You can change this to a text copy by holding down the Control key while you're dragging.
Between one text window and another, the drag defaults to a copy operation you can change this to a text movement by holding down the Shift key while dragging.

Adie support unlimited (well, the limit is large...) undo and redo capability. Each time you insert, remove, or replace some text, Adie remembers what you did.
If you make a mistake, you can undo the last command, and the one before that, and so on. Having invoked undo many times, it is sometimes desirable to invoke the redo command, i.e. to perform the original editing operation again. Thus, you can move backward or forward in time.
However if, after undoing several commands, you decide edit the buffer in a different way, then you will no longer be able to redo the undone commands:- you have now taken a different path.
When you first load a file, or just after you save it, Adie remembers that this version of the text was special; while subsequent editing commands can be undone individually, you can always quickly return to this special version of the text by means of the revert command.

You can change font by invoking the Font Selection Dialog from the Font menu. The Font Dialog displays four list boxes showing the font Family, Weight, Style, and Size of each font.
You can narrow down the number of fonts displayed by selecting a specific character set, setwidth, pitch, and whether or not scalable fonts are to be listed only.
The All Fonts checkbutton causes all fonts to be listed. Use this feature if you need to select old-style X11 bitmap fonts.
The Preview window shows a sample of text in the selected font.

The colors subpane allows you to change the colors used in the File/Directory browser, and the Text Window. You can simply drag colors from one color well to another, or you can double-click on a color well and bring up the Color Dialog. The Color Dialog offers a number of ways to create a new color, either by selecting one of the pre-defined color wells, by mixing a custom color in RGB, HSV, or CMYK color space, or by selecting a named color from a list.

The background and foreground are the normal (default) text colors. When text is selected, the selected text foreground and background are used; For temporary highlighting (e.g. brace matching), the highlight foreground and background are used.
Furthermore, the active background determines the color of the currently active text line, where the cursor is found.

When syntax coloring is enabled, text is colored based on the matching syntax rule. Each syntax rule specifies a text style, which can override all the standard text colors, as well as specify underlining or strike-throughs.
Setting a text color to clear i.e. transparent causes the default color to be taken; for example, the selected foreground color defaults to the normal foreground color, the style- based colors default to the normal colors, and so on.
This allows only a few colors to be specified, yet also enables full control over style colors if desired.

The editor subpane is used to change various modes of the editor:

Word Wrapping

This enables word wrapping mode for the Text Window; when word wrapping is turned on, text flowed to stay within the wrap margins.

Auto Indent

This causes spaces or tabs to be inserted to match the previous line; this option is meant for programmers.

Fixed Wrap Margin

When this feature is enabled, the text is flowed to stay within a fixed wrap column; when disabled, the Text Window is in continuous wrapping mode, and the text is flowed to fit the size of the Text Window. This option has no effect if the Word Wrapping option is off.

Strip Carriage Returns

When this option is selected, MS-Windows/MS-DOS text files with lines ending in CRLF are transformed into LF only files upon read; this is mostly of interest when loading DOS files on a UNIX system; when Adie runs under MS-Windows, files are normally automatically translated back and forth.

Strip Trailing Spaces

When selected, Adie will remove all white-space after the last printable character when reading a file.

Insert Tab Characters

When this option is selected, hard tab characters are inserted when entering the tab key. If the option is not selected then entering the tab key will insert the corresponding number of spaces into the text buffer.

Warn If Changed Externally

When this option is selected, a message box will appear if the file is changed external to the editor; for example, when a file is accidentally being edited twice.

Wrap Margin

This specifies the column at which paragraphs are to be wrapped; the wrap margin only has effect if the fixed wrap margin option is selected.

Tab Columns

This specifies the tab spacing, in terms of spaces.

Brace Match Time

When entering a brace, parenthesis, or bracket, the cursor temporarily jumps to the matching brace and pauses there for a bit before hopping back to the insert position. If the brace match time is set to 0, then this feature is disabled.

Mouse Wheel Lines

This is the number of lines scrolled when the mouse wheel is rotated by one notch. When holding the control key while using the wheel, the text scrolls by one page at a time; when holding the alt key, it scrolls one pixel at a time.

Line Number Space

This is the number of columns to display line numbers; setting it zero (0) will disable line number display.

Save View of File

When this option is selected, the current view or scroll position is saved so that a subsequent visit to this file can immediately jump back to the same view. Disabling this option will cause all remembered views to be forgotten.

Save Bookmarks

When selected, all currently set bookmarks will be saved for this file; a subsequent visit to this file will restore the bookmarks. Disabling this option will cause all remembered bookmarks to be forgotten.

Word Delimiters

Different programming language have different notions about identifiers. Adie accomodates for this by allowing you to specify which characters (besides white space, of course) are used to delimit identifiers or tokens in the programming language. The default set of delimiters is "!"#$%&'()*+,-./:; <= >?@[\]^`{|}~".

This subpane allows you to enter a list of file patterns, one pattern on each line. These patterns are used in the File/Directory browser and the File Dialog. They are especially useful in the File/Directory browser as it allows you to cause the File/Directory browser to only show those file types you want to see (e.g. only source files).
Each line of a pattern has the format:

patternname (patternlist)

Where patternname is the name of the pattern (e.g. "C Source") and the patternlist is a comma separated list of patterns (for example "*.h,*.c"). The patternname is optional. Some examples from my own setup of Adie are shown below:

All Files (*)
All Source (*.cpp,*.cxx,*.cc,*.C,*.c,*.hpp,*.hxx,*.hh,*.H,*.h,*.y,*.l)
C++ Source Files (*.cpp,*.cxx,*.cc,*.c,*.C)
C++ Header Files (*.h,*.hpp,*.hxx,*.hh,*.H)
C Source Files (*.c)
C Header Files (*.h)
Python Files (*.py)
Perl Files (*.pl)
Ruby Files (*.rb)
Lex (*.l)
Yacc (*.y)
Object (*.o)
X Pixmap (*.xpm)
X Bitmap (*.xbm)


Some details on the allowable wild-card patterns:

?	Matches single character.
*	Matches zero or more characters.
[abc]	Matches a single character, which must be a, b, or c.
[^abc]	Matches a single character, which must be anything other than a, b, or c.
[!abc]	Ditto.
[a-zA-Z]	Matches single character, which must be one of a-z or A-Z.
[^a-zA-Z]	Matches single character, which must be anything other than a-z or A-Z.
[!a-zA-Z]	Ditto.
pat1|pat2	Matches either pat1 or pat2.
pat1,pat2	Ditto.
(pat1|pat2)	Matches either pat1 or pat2; patterns may be nested.
(pat1,pat2)	Ditto.

Text styles determine how a particular language construct is colored. Text styles are shared between programming languages, so once you have set up a nice style combination you can use this in many syntax pattern sets.
In most cases, not all style colors need to be determined explicitly; thanks to the fallback rules, leaving a color to "clear" will indicate that the fallback value is to be used. For example, leaving the highlight foreground color "clear" indicates that the regular foreground color is to be chosen.
You can create a new style by pressing "New". You can then change the style name, and edit the colors.
To delete a style, select it and hit "Delete". Note, if any syntax patterns used this style, they may become invalid. Its usually not a good idea to delete styles after a great many patterns have been set up.

The language mode panel is used to determine language modes. Each language mode comprises a list of filename patterns, similar to the File Patterns mentioned previously.
When a pattern is matched, the corresponding syntax rules are loaded to color the file.

The Syntax Patterns Panel is used to set up syntax patterns for a given language mode.
To create or edit a set of patterns, first the desired language mode must be selected. This is done via the combobox. The list of languages is the one previously defined using the Changing Language Modes panel.

For syntax patterns, the order in which the patterns are attempted is significant. This is specified using the pattern's priority number. Patterns are tried starting from the one with the lowest priority number. As a rule, patterns which match the most text (e.g. comments) should be given the lowest priority, and patterns which are small should be given the highest.

The syntax coloring engine is capable of recursive syntax coloring, i.e. once a certain pattern is matched, the matched text can be passed to further sub-patterns, and so on. Thus, it is possible to perform context-dependent matches. For example, after recognizing a string, it is possible to separately color embedded escape sequences.

Each pattern has a text style, which is the style assigned to the text when the regular expression matches the text. Sub-patterns may assign other colors within their parent pattern.

Each pattern also has a certain amount of context, which is a number of lines of context to be examined when text is changed and needs to be incrementally recolored [this is not yet implemented 3/14/2002].

The regular expressions to use in a syntax rule are conform those of FXRex. They are PERL compatible. When specifying patterns, care must be taken not to match too much text; in many cases, lazy closures must be used. Also, remember the text is being edited, and thus very often does not conform to the programming language syntax:- the syntax patterns must therefore be safe from such inputs, and preferably yield a reasonable coloring even when text is somewhat incorrect.

Because Adie is an editor written to use the FOX Toolkit, there are various other items, common to all FOX Toolkit programs, which may be configured either by hand or using some other control panel. A few items of particular interest are list below:

[SETTINGS]
typingspeed=800
clickspeed=400
scrollspeed=80
scrolldelay=600
blinkspeed=500
animspeed=10
menupause=400
tippause=800
tiptime=3000
dragdelta=6
wheellines=1
bordercolor=black
basecolor=AntiqueWhite3
hilitecolor=AntiqueWhite
shadowcolor=AntiqueWhite4
backcolor=AntiqueWhite1
forecolor=black
selforecolor=AntiqueWhite
selbackcolor=#aea395
tipforecolor=yellow
tipbackcolor=black
normalfont="[lucidatypewriter] 90 700 1 1 0 1"
iconpath = /usr/share/icons:/home/jeroen/icons


These settings can be either placed in $HOME/.foxrc (and thus affect all FOX programs), or in $HOME/.foxrc/FoxTest/Adie (only applying to Adie). File types may be bound to a command, mime-type, and icons using statements like the one below:

[FILETYPES]
cpp = "/usr/local/bin/textedit %s &;C++ Source File;c_src.xpm;mini/c_src.xpm"
/home/jeroen = ";Home Directory;home.xpm;mini/home.xpm;application/x-folder"
defaultfilebinding = "/usr/local/bin/textedit %s &;Document;document.xpm;mini/document.xpm"
defaultexecbinding = ";Application;exec.xpm;mini/exec.xpm;application/x-executable-file"
defaultdirbinding = ";Folder;folder.xpm;mini/folder.xpm;application/x-folder"


This example shows how the extension ".cpp" is bound to the program "textedit" and is associated with two icons, a big icon "c_src.xpm" and a small icon "mini/c_src.xpm", which are to be found in the directories determined by 'iconpath", in this case, "/usr/share/icons" or "/home/jeroen/icons".
It also binds two icons "home.xpm" and "mini/home.xpm" to the home directory "/home/jeroen".
Finally, it assigns icons, commands, and mime-types to unbound documents, executables, and directories, overriding the built-in icons of the FOX Toolkit.
