1 Minimum Profit 5.x Release Notes
2 ================================
4 5.0.0-rc4
5 ---------
7 * The search hit is highlighted.
8 * When invoked from the menu, the 'record_macro' action dropped
9 the last key (bug #1245).
10 * A Curses configuration detection has been fixed that made
11 some things behave strangely, as the drop-down menu not
12 responding under some terminal configurations (bug #1247).
13 * The Curses menu no longer crashes if it doesn't fit on
14 the screen (bug #1195).
15 * The -f (execute script) command line argument really works
16 (bug #1240).
17 * New manual page (bug #1219) and README files (bug #1218).
18 * Updated documents, 'MPSL Overview' and 'Minimum Profit Cookbook'.
19 * New documents, 'Minimum Profit Data Model' and 'Creating interactive
20 dialog boxes'.
22 5.0.0-rc3
23 ---------
25 * New session support. All open documents and its current position
26 can be stored / retrieved with the new 'save_session' and
27 'load_session' actions. Two new configuration flags has
28 been added: mp.config.auto_sessions, to automatically load / save
29 sessions, and mp.config.local_sessions, to save sessions in the
30 currently active directory instead of in the home directory.
31 * Multiple key sequences for invoking actions (ala Emacs) are
32 now possible. To create them, just assign a hash to a keycode
33 instead of an action. For example, to assign the key sequence
34 Ctrl-x Ctrl-f to 'open' and Ctrl-x Ctrl-s to 'save', you can use
36 mp.keycodes['ctrl-x'] = {
37 'ctrl-f' => 'open',
38 'ctrl-s' => 'save'
39 };
41 * In the curses version, confirmations now have default values
42 (shown in brackets), activated with the ENTER key.
43 * New action 'close_all', that closes all documents.
45 5.0.0-rc2
46 ---------
48 * New 'complete' action, that asks for completion on the current
49 word using any of the words found in the same document.
50 * New 'redo' action, to revert undo operations.
51 * The global configuration file `/etc/mp.mpsl' is also executed.
52 * In the 'replace' action, the substitution string can contain
53 the special character &, that will be replaced by the matched
54 string (as in the `sed' command line tool).
56 5.0.0-rc1
57 ---------
59 * New support for translating key sequences into MP keycodes, mainly
60 for redefining ANSI sequences not supported by current terminfo /
61 termcap. For example, if your terminal sends the ANSI sequence [6;5~
62 whenever you press Ctrl+page down, you can add to your config file
63 the following line:
65 mp.add_keyseq("[6;5~", 'ctrl-page-down');
67 * A new 'system_command' action, to pipe from and to system commands
68 (Closed bug #1120).
69 * A new 'word_count' action, to count the number of lines and words
70 in a document (or in the selected block).
71 * Incorrect word wrapping has been fixed (Closed bug #1137).
72 * Search and replace expand backslashed characters like \n and \t
73 (Closed bug #1214).
74 * New timer functionality has been added; a user function can be called
75 each time a specified period of milliseconds have elapsed. If, for
76 example, you want to print a string on standard output each two
77 seconds, you can run
79 mp.timer(2000, sub { print("Hi, world!\n"); });
81 5.0.0-pre1
82 ----------
84 * Password-protected files fully work.
85 * Moving to next / previous instance of character (bound to ctrl-page-down
86 and ctrl-page-up) works (Closed bug #1131).
87 * Files open MUCH faster.
88 * Selection can be done by pressing shift + any movement key (Closed bug #1182).
89 * Dialog boxes work under Windows 98 (Closed bugs #1196, #1197).
90 * Block selection can be done by dragging the mouse (Closed bugs #1200, #1201).
91 * New 'grep' functionality (Closed bug #1116).
92 * New action 'sync' (save all modified documents, closed bug #1206).
93 * New action 'document_list' (show a box with all open documents, allowing
94 the selection of the active one; closed bug #1211).
95 * Translations ported from mp 3.x (closed bug #1169).
96 * Most syntax highlight definitions ported from mp 3.x (closed bug #1168).
98 4.99.12
99 -------
101 * The menu in the Curses interface has been (finally) implemented.
102 * Interfaces have changed internally; a new driver function, mp.drv.form()
103 serves as a dialog box generic generator, resulting in more useful queries
104 for data (for example, all data required for a 'replace' operation is
105 queried in only one dialog box). The Curses implementation, though
106 functional, is still just a wrapper to the old interface functions
107 and fields are queried one-by-one (which is annoying). This is an example
108 of a call to mp.drv.form(); the r variable will contain an array of 5
109 elements (one per widget) containing the values, or NULL if user cancelled:
111 local r = mp.drv.form( [
113 /* a 'text' widget */
114 { 'label' => "Replace this:",
115 'type' => 'text',
116 'history' => 'search',
117 'value' => 'THIS' },
119 /* another one */
120 { 'label' => "With:",
121 'type' => 'text',
122 'history' => 'replace',
123 'value' => 'THAT' },
125 /* a 'password' widget */
126 { 'label' => 'Password:',
127 'type' => 'password' },
129 /* a 'checkbox' widget */
130 { 'label' => "Case sensitive:",
131 'type' => 'checkbox',
132 'value' => mp.config.case_sensitive_search },
134 /* a 'list' widget */
135 { 'label' => 'All C files:',
136 'type' => 'list',
137 'list' => glob('*.c'),
138 'value' => 10 }
139 ] );
141 * Password protecting files works (but they cannot be opened yet, so this
142 is far from useful, unless you use mp 3.x to open them).
143 * Case sensitivity in searches can be controlled with the new
144 config flag mp.config.case_sensitive_search.
145 * Replace (and global replace by use of the new config flag
146 'mp.config.global_replace') works.
148 4.99.11
149 -------
151 * Syntax highlight definition have changed (again, hopefully for the last
152 time). Definitions are now an array of attribute name / regexes in which
153 the order is significative.
154 * Template insertion works.
155 * Tag selection (open the file where a symbol is defined) works.
156 * Symbol completion (using tags) works.
157 * Closed bugs #1159, #1158, #1153, #1161.
159 4.99.10
160 -------
162 * A big advance in the Curses interface: Alerts, confirmations, and open
163 file, save file, search and generic prompts are working. Still lacking
164 the selection lists (as the rest of interfaces) and the menu.
165 * Improved menus: if an invalid action is added to a menu, it's shown
166 followed by a ?; if a key is bound to that action, it's shown between
167 square brackets.
168 * For systems lacking iconv support (MS Windows), a crappy, ad-hoc utf-8
169 converter has been added. This means that hitting 'escape' and typing
171 encoding('utf-8');
173 makes reading and writing utf-8 encoded files possible on every system.
174 * New action 'join_paragraph', to join current paragraph all in one line.
175 * New action 'word_wrap_paragraph', that re-word-wraps current paragraph.
176 Word wrapping must be set ('mp.config.word_wrap = number;') for this to
177 work.
179 4.99.9
180 ------
182 * The GTK and win32 drivers now include a native open/save file dialog.
183 * Interactive help (help for the word under the cursor, triggered by
184 pressing 'f1') works.
185 * The menu in GTK and win32 works.
186 * New icon!
187 * Some bugs that caused random crashes has been fixed.
188 * New action 'exec-doc', that executes the active open document as
189 MPSL code.
191 4.99.8
192 ------
194 * New configuration option mp.config.tabs_as_spaces, to store tabs
195 as spaces.
196 * Each syntax highlight definition can contain an optional function
197 called detect() that receives the document as argument and can be used
198 to tailor special detection rules.
199 * A big part of the internal storage of colors and attributes have
200 been rewritten to make it more dynamic.
201 * Tag target for the word over the cursor is shown in the status line.
202 * Move word left works.
203 * Opening an already open file makes it the active one instead of
204 re-opening it.
205 * The 'execute code' action has been remapped from ctrl-f1 to escape.
206 * Spellchecking via ispell works (though it's SLOW!). Activate it by
207 hitting escape and typing:
209 mp.ispell(1);
211 * By default, files are now unlinked before (re)written. File permissions
212 and ownership are restored if available. This behaviour can be disabled
213 by setting mp.config.unlink to 0.
214 * The GTK driver drawing code has been optimized, so it's much more
215 responsive now.
217 4.99.7
218 ------
220 * The 'modified' flag of documents is maintained, so now closing files
221 with pending modifications ask for confirmation. Also, the %m status
222 line directive works (marking modified files with an asterisk).
223 * Flex and bison are no longer needed to build.
224 * The 'close window' button in GUIs (win32 and GTK) now generate the
225 special keycode 'close-window'.
226 * The 'exit' action now closes all open documents, asking for saving
227 confirmation on those modified.
228 * Temporary versions of the 'open' ans 'save' actions (using
229 mp.drv.readline() instead of an ad-hoc open file dialog) have
230 been implemented.
231 * The GUI interfaces now can have their font preferences configured
232 by using mp.config.font_face and mp.config.font_size.
233 * The actions 'zoom-in' and 'zoom-out' (font size rescaling, bound to
234 F11/F12 and ctrl-kp-minus/ctrl-kp-plus) have been implemented.
235 * New mouse-related actions: move-to-mouse-position, move-mouse-wheel-up
236 and move-mouse-wheel-down.
238 4.99.6
239 ------
241 This is an EXPERIMENTAL version for evaluation purposes only. There are
242 many things that aren't implemented, others fail miserably and many more
243 do it incorrectly. Basically, what is known to work is:
245 * Basic text editing fully works. I've been using it for six months or so
246 to maintain itself, and there has not been a crash in three months,
247 more or less.
248 * Scripting works fine (90% of Minimum Profit 5.x itself is implemented
249 in MPSL, its internal scripting language).
250 * Undo works fine. It's bound to ctrl-z.
251 * Works cleanly in an UTF-8 environment.
253 I do development on the GTK version, so it's where it works best. The
254 curses version lacks many of the interface (alerts, confirmations,
255 asking for text, etc.), so it's barely usable. The win32 version seem
256 to work, but it needs to be manually installed and probably need some
257 tweaking.
259 What it doesn't work:
261 * The dialogs to open or save a file by its name aren't implemented.
262 There are workarounds for this: files can be opened from the command
263 line and save works correctly if the edited file has a name. Also,
264 files can be opened by hitting ctrl-f1 (execute script code) and
265 typing:
267 mp.open("file-to-be-opened");
269 * There is no menu.
270 * No ispell support.
271 * No password protected files.
272 * No grep.
273 * No external commands (so no support for help, tags, etc.).
274 * Some movement commands as moving a word left, moving to matching
275 brackets, etc. are still not implemented.
276 * Only a few syntax highlight definitions are implemented.
277 * Many other things I cannot remember.
279 Documentation is still scarce: the more interesting bits are inside the
280 mpsl/doc directory. This is where the scripting language is documented,
281 with some basic overviews and implementation notes (there is even an
282 embryo of a PostScript quick reference guide).
284 Customizing can be done by writing MPSL commands in the ~/.mp.mpsl file,
285 which is read on startup.
287 I have not tried to optimize the internal engine, so it's probably some
288 magnitudes slower than the 3.x version.
