** Many new coding systems are available by loading the `code-pages' |
202 |
|
library. These include complete versions of most of those in |
203 |
|
codepage.el, based on Unicode mappings. |
204 |
|
|
205 |
|
** The utf-8 coding system has been enhanced. Untranslatable utf-8 |
206 |
|
sequences (mostly representing CJK characters) are composed into |
207 |
|
single quasi-characters. User option `utf-translate-cjk' arranges to |
208 |
|
translate many utf-8 CJK character sequences into real Emacs |
209 |
|
characters in a similar way to the Mule-UCS system. The utf-8 coding |
210 |
|
system will now encode characters from most of Emacs's one-dimensional |
211 |
|
internal charsets, specifically the ISO-8859 ones. |
212 |
|
|
213 |
|
** iso-10646-1 (`Unicode') fonts can be used to display any range of |
214 |
|
characters encodable by the utf-8 coding system. Just specify the |
215 |
|
fontset appropriately. |
216 |

|
217 |
|
** New command `ucs-insert' inserts a character specified by its |
218 |
|
unicode. |
219 |
|
|
220 |
|
+++ |
221 |
|
** Limited support for character `unification' has been added. |
222 |
|
Emacs now knows how to translate between different representations of |
223 |
|
the same characters in various Emacs charsets according to standard |
224 |
|
Unicode mappings. This applies mainly to characters in the ISO 8859 |
225 |
|
sets plus some other 8-bit sets, but can be extended. For instance, |
226 |
|
translation works amongst the Emacs ...-iso8859-... charsets and the |
227 |
|
mule-unicode-... ones. |
228 |
|
|
229 |
|
By default this translation will happen automatically on encoding. |
230 |
|
Self-inserting characters are translated to make the input conformant |
231 |
|
with the encoding of the buffer in which it's being used, where |
232 |
|
possible. |
233 |
|
|
234 |
|
You can force a more complete unification with the user option |
235 |
|
unify-8859-on-decoding-mode. That maps all the Latin-N character sets |
236 |
|
into Unicode characters (from the latin-iso8859-1 and |
237 |
|
mule-unicode-0100-24ff charsets) on decoding. Note that this mode |
238 |
|
will often effectively clobber data with an iso-2022 encoding. |
239 |
|
|
240 |
|
** There is support for decoding Greek and Cyrillic characters into |
241 |
|
either Unicode (the mule-unicode charsets) or the iso-8859 charsets, |
242 |
|
when possible. The latter are more space-efficient. This is |
243 |
|
controlled by user option utf-fragment-on-decoding. |
244 |
|
|
245 |
|
** The new command `set-file-name-coding-system' (C-x RET F) sets |
246 |
|
coding system for encoding and decoding file names. A new menu item |
247 |
|
(Options->Mule->Set Coding Systems->For File Name) invokes this |
248 |
|
command. |

** Controlling the left and right fringe widths. |
+++ |
|
|
|
|
The left and right fringe widths can now be controlled by setting the |
|
|
`left-fringe' and `right-fringe' frame parameters to an integer value |
|
|
specifying the width in pixels. Setting the width to 0 effectively |
|
|
removes the corresponding fringe. |
|
|
|
|
|
The actual fringe widths may deviate from the specified widths, since |
|
|
the combined fringe widths must match an integral number of columns. |
|
|
The extra width is distributed evenly between the left and right fringe. |
|
|
For force a specific fringe width, specify the width as a negative |
|
|
integer (if both widths are negative, only the left fringe gets the |
|
|
specified width). |
|
|
|
|
|
Setting the width to nil (the default), restores the default fringe |
|
|
width which is the minimum number of pixels necessary to display any |
|
|
of the currently defined fringe bitmaps. The width of the built-in |
|
|
fringe bitmaps is 8 pixels. |

*** New regular expressions features |
769 |
|
|
770 |
|
**** New syntax for regular expressions, multi-line regular expressions. |
771 |
|
The syntax --ignore-case-regexp=/regex/ is now undocumented and retained |
772 |
|
only for backward compatibility. The new equivalent syntax is |
773 |
|
--regex=/regex/i. More generally, it is --regex=/TAGREGEX/TAGNAME/MODS, |
774 |
|
where `/TAGNAME' is optional, as usual, and MODS is a string of 0 or |
775 |
|
more characters among `i' (ignore case), `m' (multi-line) and `s' |
776 |
|
(single-line). The `m' and `s' modifiers behave as in Perl regular |
777 |
|
expressions: `m' allows regexps to match more than one line, while `s' |
778 |
|
(which implies `m') means that `.' matches newlines. The ability to |
779 |
|
span newlines allows writing of much more powerful regular expressions |
780 |
|
and rapid prototyping for tagging new languages. |
781 |
|
|
782 |
|
**** Regular expressions can use char escape sequences as in Gcc. |
783 |
|
The escaped character sequence \a, \b, \d, \e, \f, \n, \r, \t, \v, |
784 |
|
respectively, stand for the ASCII characters BEL, BS, DEL, ESC, FF, NL, |

|
CR, TAB, VT, |
786 |
|
|
787 |
|
**** Regular expressions can be bound to a given language. |
788 |
|
The syntax --regex={LANGUAGE}REGEX means that REGEX is used to make tags |
789 |
|
only for files of language LANGUAGE, and ignored otherwise. This is |
790 |
|
particularly useful when storing regexps in a file. |

1029 |
|
|
1030 |
|
** The new keypad setup package provides several common bindings for |
1031 |
|
the numeric keypad which is available on most keyboards. The numeric |
1032 |
|
keypad typically has the digits 0 to 9, a decimal point, keys marked |
1033 |
|
+, -, /, and *, an Enter key, and a NumLock toggle key. The keypad |
1034 |
|
package only controls the use of the digit and decimal keys. |
1035 |
|
|
1036 |
|
By customizing the variables `keypad-setup', `keypad-shifted-setup', |
1037 |
|
`keypad-numlock-setup', and `keypad-numlock-shifted-setup', or by |
1038 |
|
using the function `keypad-setup', you can rebind all digit keys and |
1039 |
|
the decimal key of the keypad in one step for each of the four |
1040 |
|
possible combinations of the Shift key state (not pressed/pressed) and |
1041 |
|
the NumLock toggle state (off/on). |
1042 |
|
|
1043 |
|
The choices for the keypad keys in each of the above states are: |
1044 |
|
`Plain numeric keypad' where the keys generates plain digits, |
1045 |
|
`Numeric keypad with decimal key' where the character produced by the |
1046 |
|
decimal key can be customized individually (for internationalization), |
1047 |
|
`Numeric Prefix Arg' where the keypad keys produce numeric prefix args |
1048 |
|
for emacs editing commands, `Cursor keys' and `Shifted Cursor keys' |
1049 |
|
where the keys work like (shifted) arrow keys, home/end, etc., and |
1050 |
|
`Unspecified/User-defined' where the keypad keys (kp-0, kp-1, etc.) |
1051 |
|
are left unspecified and can be bound individually through the global |
1052 |
|
or local keymaps. |
1053 |
|
|
1054 |
|
** The new kmacro package provides a simpler user interface to |
1055 |
|
emacs' keyboard macro facilities. |
1056 |
|
|
1057 |
|
Basically, it uses two function keys (default F3 and F4) like this: |
1058 |
|
F3 starts a macro, F4 ends the macro, and pressing F4 again executes |
1059 |
|
the last macro. While defining the macro, F3 inserts a counter value |
1060 |
|
which automatically increments every time the macro is executed. |
1061 |
|
|
1062 |
|
There is now a keyboard macro ring which stores the most recently |
1063 |
|
defined macros. |
1064 |
|
|
1065 |
|
The C-x C-k sequence is now a prefix for the kmacro keymap which |
1066 |
|
defines bindings for moving through the keyboard macro ring, |
1067 |
|
C-x C-k C-p and C-x C-k C-n, editing the last macro C-x C-k C-e, |
1068 |
|
manipulating the macro counter and format via C-x C-k C-c, |
1069 |
|
C-x C-k C-a, and C-x C-k C-f. See the commentary in kmacro.el |
1070 |
|
for more commands. |
1071 |
|
|
1072 |
|
The normal macro bindings C-x (, C-x ), and C-x e now interfaces to |
1073 |
|
the keyboard macro ring. |
1074 |
|
|
1075 |
|
The C-x e command now automatically terminates the current macro |
1076 |
|
before calling it, if used while defining a macro. |
1077 |
|
|
1078 |
|
In addition, when ending or calling a macro with C-x e, the macro can |
1079 |
|
be repeated immediately by typing just the `e'. You can customize |
1080 |
|
this behaviour via the variable kmacro-call-repeat-key and |
1081 |
|
kmacro-call-repeat-with-arg. |
1082 |
|
|
1083 |
|
Keyboard macros can now be debugged and edited interactively. |
1084 |
|
C-x C-k SPC will step through the last keyboard macro one key sequence |
1085 |
|
at a time, prompting for the actions to take. |
1086 |
|
|
1087 |

--- |
1088 |
|
** The old Octave mode bindings C-c f and C-c i have been changed |
1089 |
|
to C-c C-f and C-c C-i. The C-c C-i subcommands now have duplicate |
1090 |
|
bindings on control characters--thus, C-c C-i C-b is the same as |
1091 |
|
C-c C-i b, and so on. |

|
the .emacs file, the normal Print item on the File menu is replaced |
1097 |
|
with a Print sub-menu which allows you to preview output through |
1098 |

** Byte compiler changes: |
1230 |
|
|
1231 |
|
*** `(featurep 'xemacs)' is treated by the compiler as nil. This |
1232 |
|
helps to avoid noisy compiler warnings in code meant to run under both |
1233 |
|
Emacs and XEmacs and may sometimes make the result significantly more |
1234 |
|
efficient. Since byte code from recent versions of XEmacs won't |
1235 |
|
generally run in Emacs and vice versa, this optimization doesn't lose |
1236 |
|
you anything. |
1237 |
|
|
1238 |
|
*** You can avoid warnings for possibly-undefined symbols with a |
1239 |
|
simple convention that the compiler understands. (This is mostly |
1240 |
|
useful in code meant to be portable to different Emacs versions.) |
1241 |
|
Write forms like the following, or code that macroexpands into such |
1242 |
|
forms: |
1243 |
|
|
1244 |
|
(if (fboundp 'foo) <then> <else>) |
1245 |
|
(if (boundp 'foo) <then> <else) |
1246 |
|
|
1247 |
|
In the first case, using `foo' as a function inside the <then> form |
1248 |
|
won't produce a warning if it's not defined as a function, and in the |
1249 |
|
second case, using `foo' as a variable won't produce a warning if it's |
1250 |
|
unbound. The test must be in exactly one of the above forms (after |
1251 |
|
macro expansion), but such tests may be nested. Note that `when' and |
1252 |
|
`unless' expand to `if', but `cond' doesn't. |

** New Lisp library testcover.el works with edebug to help you determine |
1262 |
|
whether you've tested all your Lisp code. Function testcover-start |
1263 |
|
instruments all functions in a given file. Then test your code. Function |
1264 |
|
testcover-mark-all adds overlay "splotches" to the Lisp file's buffer to |
1265 |
|
show where coverage is lacking. Command testcover-next-mark (bind it to |
1266 |
|
a key!) will move point forward to the next spot that has a splotch. |
1267 |
|
|
1268 |
|
*** Normally, a red splotch indicates the form was never completely evaluated; |
1269 |
|
a brown splotch means it always evaluated to the same value. The red |
1270 |
|
splotches are skipped for forms that can't possibly complete their evaluation, |
1271 |
|
such as `error'. The brown splotches are skipped for forms that are expected |
1272 |
|
to always evaluate to the same value, such as (setq x 14). |
1273 |
|
|
1274 |
|
*** For difficult cases, you can add do-nothing macros to your code to help |
1275 |
|
out the test coverage tool. The macro 1value suppresses a brown splotch for |
1276 |
|
its argument. The macro noreturn suppresses a red splotch. |

needed. |

** If a function has a non-nil `safe-local-eval-function' property, |

ok. If the property is a function or list of functions, they are called |

** Controlling the left and right fringe widths. |

The left and right fringe widths can now be controlled by setting the |
1348 |

`left-fringe' and `right-fringe' frame parameters to an integer value |
1349 |

specifying the width in pixels. Setting the width to 0 effectively |
1350 |
|
removes the corresponding fringe. |
1351 |
|
|
1352 |
|
The actual fringe widths may deviate from the specified widths, since |
1353 |
|
the combined fringe widths must match an integral number of columns. |
1354 |
|
The extra width is distributed evenly between the left and right fringe. |
1355 |
|
For force a specific fringe width, specify the width as a negative |
1356 |

integer (if both widths are negative, only the left fringe gets the |
1357 |
|
specified width). |
1358 |

Setting the width to nil (the default), restores the default fringe |

1579 |

The `insert-for-yank' function looks for a yank-handler property on |
1581 |
|
the first character on its string argument (typically the first |
1582 |
|
element on the kill-ring). If a yank-handler property is found, |
1583 |
|
the normal behaviour of `insert-for-yank' is modified in various ways: |
1584 |
|
|
1585 |
|
When FUNCTION is present and non-nil, it is called instead of `insert' |
1586 |
|
to insert the string. FUNCTION takes one argument--the object to insert. |
1587 |
|
If PARAM is present and non-nil, it replaces STRING as the object |
1588 |
|
passed to FUNCTION (or `insert'); for example, if FUNCTION is |
1589 |
|
`yank-rectangle', PARAM should be a list of strings to insert as a |
1590 |
|
rectangle. |
1591 |
|
If NOEXCLUDE is present and non-nil, the normal removal of the |
1592 |
|
yank-excluded-properties is not performed; instead FUNCTION is |
1593 |
|
responsible for removing those properties. This may be necessary |
1594 |
|
if FUNCTION adjusts point before or after inserting the object. |
1595 |
|
If UNDO is present and non-nil, it is a function that will be called |
1596 |
|
by `yank-pop' to undo the insertion of the current object. It is |
1597 |
|
called with two arguments, the start and end of the current region. |
1598 |
|
FUNCTION may set `yank-undo-function' to override the UNDO value. |
