Minimum Profit Release Notes

5.1.4

If a block is selected, any keystroke substitutes it.
Support for Alt + keys (ASCII and movement) has been added, and mostly left unbound to be used by the user for his own keybindings.
A new tab mode, which uses the previous line as a template for tab columns.
Fixed action open_under_cursor.
The mp.paste() function returns the clipboard content as a string if called without arguments.
New Grutatxt syntax highlighter.
Fix F10 in Win32.
Fix a bug when calculating the drawing position in the selected block, that were leading to crashes.

5.1.3

A new Qt4 driver (adapted from the KDE4 driver).
A new hexadecimal viewer.
New action open_dropped_files, to open files dropped from the underlying system GUI.
Improved file encoding autodetection by looking at the UTF BOM marks.
New configuration option keep_eol, to keep the original end of line sequence each document had.
Fixed some clipboard issues, as replacing the selected block when pasting and some crashes.
win32 executable has been renamed to mp-5.exe.
The status line format string can also include the %e token to show the encoding used by the document.
Fixed win32 input processing in non-latin environments.
Setting an empty encoding (to fall back to system defaults) always work.

5.1.2

The grep action can now be recursive.
New syntax color for special documentation blocks.
Fix searching into empty selected blocks (this was bug #1269).
New action section_list, that shows a list of sections in the current document to jump to. Sections are usually function definitions and special marks in programming languages.
New action seek_misspelled, to search the next misspelled word. It has been assigned to keycode f5.
New action ignore_last_misspell, to add the last misspelled word found by seek_misspelled to a whitelist so it won't be found again.
New action seek_repeated_word, to search for words starting or ending with the same number of letters up to a maximum distance. It's controlled by the new configuration directives mp.config.rw_num_chars and mp.config.rw_max_dist. It has been assigned to keycode f6 (this keycode was previously assigned to join_paragraph, which has no keybinding now).
The action open_templates_file has been fixed.
Several GTK interface updates by fellow developer Sebastian Vöcking.
New command line option -d, to change the working directory.
Several fixes to the win32 driver; word wrapping, combobox drop-down sizes, underlined text.
Avoid hanging if the external ispell program is broken.
The dump() function now dumps its argument as MPSL code.

5.1.1

Internationalization works in all platforms (including KDE4, were it was faulty, and win32, where it was non-existent since the 3.x series).
The status line format string can also include the %w token to show the number of words in the current document or selection (can be slow).
Search and replace is now limited to the selected block, if any.

5.1.0

Fixes to the KDE4 driver:

Underlined text works.
Text fields in forms now have history.
If no xserver can be contacted, fall back to the curses interface.

5.1.0-rc1

KDE4 support.
Rectangular block copy/paste support.
New syntax highlight for the Euphoria language.

5.0.3

New action open_under_cursor, that picks the word in the current document under the cursor, accepts it as a document name and tries to open it. If it's in the format string:number, is accepted as a file name and a line number. It's bound by default to ctrl-enter (alt-enter under Curses).
The grep action bevahaviour has changed; instead of in a form, matches are shown in a read-only document that is only closed explicitly. Each change can be moved to by using the new open_under_cursor (ctrl-enter or alt-enter) action shown above.
In a similar way, the build action also shows its output in a read-only document instead of a form that is not automatically closed, making the browsing and editing of compilation errors more useful.
Forms in the Curses driver have changed their look. All fields in a form are shown simultaneously on screen. This is one step to close bug #1249.
A set of character encoding converters have been natively implemented, improving those platforms where the 'iconv' library is not available (i.e. Windows and old Unix systems). The available encodings can be shown by executing

	dump(EMBEDDED_ENCODINGS);

5.0.2

New option to mark end of line characters, with its associated configuration directive (mp.config.mark_eol).
The end of line string (mp.config.eol) is now system-dependent (so, on win32, it's set by default to \r\n).
Copy and paste on GTK has been fixed (this was bug #1205).
Fixed some redrawing issues (bug #1236 and others).
Ctrl-keys no longer fail on GTK (bug #1252).
New document Minimum Profit Action Reference.
New action build, for building Makefile-based projects. See the action reference for details.

5.0.1

Improved line edition in the Curses interface (full edition plus file expansion using the tab key in open / save file prompts).
Auto-indenting is temporarily disabled while pasting (bug #1250).
New document Minimum Profit Function Reference (contributed by Lee Page).

5.0.0

The search hit is highlighted.
When invoked from the menu, the record_macro action dropped the last key (bug #1245).
A Curses configuration detection has been fixed that made some things behave strangely, as the drop-down menu not responding under some terminal configurations (bug #1247).
The Curses menu no longer crashes if it doesn't fit on the screen (bug #1195).
The -f (execute script) command line argument really works (bug #1240).
New manual page (bug #1219) and README files (bug #1218).
Updated documents, MPSL Overview and Minimum Profit Cookbook.
New documents, Minimum Profit Data Model and Creating interactive dialog boxes.

5.0.0-rc3

New session support. All open documents and its current position can be stored / retrieved with the new save_session and load_session actions. Two new configuration flags has been added: mp.config.auto_sessions, to automatically load / save sessions, and mp.config.local_sessions, to save sessions in the currently active directory instead of in the home directory.
Multiple key sequences for invoking actions (ala Emacs) are now possible. To create them, just assign a hash to a keycode instead of an action. For example, to assign the key sequence Ctrl-x Ctrl-f to open and Ctrl-x Ctrl-s to save, you can use

	mp.keycodes['ctrl-x'] = {
		'ctrl-f'	=> 'open',
		'ctrl-s'	=> 'save'
	};

In the curses version, confirmations now have default values (shown in brackets), activated with the ENTER key.
New action close_all, that closes all documents.

5.0.0-rc2

New complete action, that asks for completion on the current word using any of the words found in the same document.
New redo action, to revert undo operations.
The global configuration file /etc/mp.mpsl is also executed.
In the replace action, the substitution string can contain the special character &, that will be replaced by the matched string (as in the sed command line tool).

5.0.0-rc1

New support for translating key sequences into MP keycodes, mainly for redefining ANSI sequences not supported by current terminfo / termcap. For example, if your terminal sends the ANSI sequence [6;5~ whenever you press Ctrl+page down, you can add to your config file the following line:

	mp.add_keyseq("[6;5~", 'ctrl-page-down');

A new system_command action, to pipe from and to system commands (Closed bug #1120).
A new word_count action, to count the number of lines and words in a document (or in the selected block).
Incorrect word wrapping has been fixed (Closed bug #1137).
Search and replace expand backslashed characters like \n and \t (Closed bug #1214).
New timer functionality has been added; a user function can be called each time a specified period of milliseconds have elapsed. If, for example, you want to print a string on standard output each two seconds, you can run

	mp.timer(2000, sub { print("Hi, world!\n"); });

5.0.0-pre1

Password-protected files fully work.
Moving to next / previous instance of character (bound to ctrl-page-down and ctrl-page-up) works (Closed bug #1131).
Files open MUCH faster.
Selection can be done by pressing shift + any movement key (Closed bug #1182).
Dialog boxes work under Windows 98 (Closed bugs #1196, #1197).
Block selection can be done by dragging the mouse (Closed bugs #1200, #1201).
New grep functionality (Closed bug #1116).
New action sync (save all modified documents, closed bug #1206).
New action document_list (show a box with all open documents, allowing the selection of the active one; closed bug #1211).
Translations ported from mp 3.x (closed bug #1169).
Most syntax highlight definitions ported from mp 3.x (closed bug #1168).

4.99.12

The menu in the Curses interface has been (finally) implemented.
Interfaces have changed internally; a new driver function, mp.drv.form() serves as a dialog box generic generator, resulting in more useful queries for data (for example, all data required for a replace operation is queried in only one dialog box). The Curses implementation, though functional, is still just a wrapper to the old interface functions and fields are queried one-by-one (which is annoying). This is an example of a call to mp.drv.form(); the r variable will contain an array of 5 elements (one per widget) containing the values, or NULL if user cancelled:

	local r = mp.drv.form( [
	
		/* a 'text' widget */
		{ 'label'	=> "Replace this:",
		  'type'	=> 'text',
		  'history'	=> 'search',
		  'value'	=> 'THIS' },
	
		/* another one */
		{ 'label'	=> "With:",
		  'type'	=> 'text',
		  'history'	=> 'replace',
		  'value'	=> 'THAT' },
	
		/* a 'password' widget */
		{ 'label'	=> 'Password:',
		  'type'	=> 'password' },
	
		/* a 'checkbox' widget */
		{ 'label'	=> "Case sensitive:",
		  'type'	=> 'checkbox',
		  'value'	=> mp.config.case_sensitive_search },
	
		/* a 'list' widget */
		{ 'label'	=> 'All C files:',
		  'type'	=> 'list',
		  'list'	=> glob('*.c'),
		  'value'	=> 10 }
	] );

Password protecting files works (but they cannot be opened yet, so this is far from useful, unless you use mp 3.x to open them).
Case sensitivity in searches can be controlled with the new config flag mp.config.case_sensitive_search.
Replace (and global replace by use of the new config flag mp.config.global_replace) works.

4.99.11

Syntax highlight definition have changed (again, hopefully for the last time). Definitions are now an array of attribute name / regexes in which the order is significative.
Template insertion works.
Tag selection (open the file where a symbol is defined) works.
Symbol completion (using tags) works.
Closed bugs #1159, #1158, #1153, #1161.

4.99.10

A big advance in the Curses interface; alerts, confirmations, and open file, save file, search and generic prompts are working. Still lacking the selection lists (as the rest of interfaces) and the menu.
Improved menus; if an invalid action is added to a menu, it's shown followed by a ?; if a key is bound to that action, it's shown between square brackets.
For systems lacking iconv support (MS Windows), a crappy, ad-hoc utf-8 converter has been added. This means that hitting escape and typing encoding(utf-8');' makes reading and writing utf-8 encoded files possible on every system.
New action join_paragraph, to join current paragraph all in one line.
New action word_wrap_paragraph, that re-word-wraps current paragraph. Word wrapping must be set ('mp.config.word_wrap = number;') for this to work.

4.99.9

The GTK and win32 drivers now include a native open/save file dialog.
Interactive help (help for the word under the cursor, triggered by pressing f1) works.
The menu in GTK and win32 works.
New icon!
Some bugs that caused random crashes has been fixed.
New action exec-doc, that executes the active open document as MPSL code.

4.99.8

New configuration option mp.config.tabs_as_spaces, to store tabs as spaces.
Each syntax highlight definition can contain an optional function called detect() that receives the document as argument and can be used to tailor special detection rules.
A big part of the internal storage of colors and attributes have been rewritten to make it more dynamic.
Tag target for the word over the cursor is shown in the status line.
Move word left works.
Opening an already open file makes it the active one instead of re-opening it.
The execute code action has been remapped from ctrl-f1 to escape.
Spellchecking via ispell works (though it's SLOW!). Activate it by hitting escape and typing:

	mp.ispell(1);

By default, files are now unlinked before (re)written. File permissions and ownership are restored if available. This behaviour can be disabled by setting mp.config.unlink to zero.
The GTK driver drawing code has been optimized, so it's much more responsive now.

4.99.7

The modified flag of documents is maintained, so now closing files with pending modifications ask for confirmation. Also, the %m status line directive works (marking modified files with an asterisk).
Flex and bison are no longer needed to build.
The close window button in GUIs (win32 and GTK) now generate the special keycode close-window.
The exit action now closes all open documents, asking for saving confirmation on those modified.
Temporary versions of the open ans save actions (using mp.drv.readline() instead of an ad-hoc open file dialog) have been implemented.
The GUI interfaces now can have their font preferences configured by using mp.config.font_face and mp.config.font_size.
The actions zoom-in and zoom-out (font size rescaling, bound to f11/f12 and ctrl-kp-minus/ctrl-kp-plus) have been implemented.
New mouse-related actions; move-to-mouse-position, move-mouse-wheel-up and move-mouse-wheel-down.

4.99.6

This is an EXPERIMENTAL version for evaluation purposes only. There are many things that aren't implemented, others fail miserably and many more do it incorrectly. Basically, what is known to work is:

Basic text editing fully works. I've been using it for six months or so to maintain itself, and there has not been a crash in three months, more or less.
Scripting works fine (90% of Minimum Profit 5.x itself is implemented in MPSL, its internal scripting language).
Undo works fine. It's bound to ctrl-z.
Works cleanly in an UTF-8 environment.

I do development on the GTK version, so it's where it works best. The curses version lacks many of the interface (alerts, confirmations, asking for text, etc.), so it's barely usable. The win32 version seem to work, but it needs to be manually installed and probably need some tweaking.

What it doesn't work:

The dialogs to open or save a file by its name aren't implemented. There are workarounds for this: files can be opened from the command line and save works correctly if the edited file has a name. Also, files can be opened by hitting ctrl-f1 (execute script code) and typing:

	mp.open("file-to-be-opened");

There is no menu.
No ispell support.
No password protected files.
No grep.
No external commands (so no support for help, tags, etc.).
Some movement commands as moving a word left, moving to matching brackets, etc. are still not implemented.
Only a few syntax highlight definitions are implemented.
Many other things I cannot remember.

Documentation is still scarce: the more interesting bits are inside the mpsl/doc directory. This is where the scripting language is documented, with some basic overviews and implementation notes (there is even an embryo of a PostScript quick reference guide).

Customizing can be done by writing MPSL commands in the ~/.mp.mpsl file, which is read on startup.

I have not tried to optimize the internal engine, so it's probably some magnitudes slower than the 3.x version.
