22FREQUENTLY ASKED QUESTIONS 22FREQUENTLY ASKED QUESTIONS
23 The new selection selects pieces that are too big, how can I select
24 single words?
25 Yes. For example, if you want to select alphanumeric words, you can
26 use the following resource:
27
28 URxvt.selection.pattern-0: ([[:word:]]+)
29
30 If you click more than twice, the selection will be extended more
31 and more.
32
33 To get a selection that is very similar to the old code, try this
34 pattern:
35
36 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
37
38 Please also note that the *LeftClick Shift-LeftClik* combination
39 also selects words like the old code.
40
41 I don't like the new selection/popups/hotkeys/perl, how do I
42 change/disable it?
43 You can disable the perl extension completely by setting the
44 perl-ext-common resource to the empty string, which also keeps
45 rxvt-unicode from initialising perl, saving memory.
46
47 If you only want to disable specific features, you first have to
48 identify which perl extension is responsible. For this, read the
49 section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
50 example, to disable the selection-popup and option-popup, specify
51 this perl-ext-common resource:
52
53 URxvt.perl-ext-common: default,-selection-popup,-option-popup
54
55 This will keep the default extensions, but disable the two popup
56 extensions. Some extensions can also be configured, for example,
57 scrollback search mode is triggered by M-s. You can move it to any
58 other combination either by setting the searchable-scrollback
59 resource:
60
61 URxvt.searchable-scrollback: CM-s
62
63 Isn't rxvt supposed to be small? Don't all those features bloat?
64 I often get asked about this, and I think, no, they didn't cause
65 extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
66 can see that the urxvt binary is larger (due to some encoding tables
67 always being compiled in), but it actually uses less memory (RSS)
68 after startup. Even with "--disable-everything", this comparison is
69 a bit unfair, as many features unique to urxvt (locale, encoding
70 conversion, iso14755 etc.) are already in use in this mode.
71
72 text data bss drs rss filename
73 98398 1664 24 15695 1824 rxvt --disable-everything
74 188985 9048 66616 18222 1788 urxvt --disable-everything
75
76 When you "--enable-everything" (which _is_ unfair, as this involves
77 xft and full locale/XIM support which are quite bloaty inside libX11
78 and my libc), the two diverge, but not unreasnobaly so.
79
80 text data bss drs rss filename
81 163431 2152 24 20123 2060 rxvt --enable-everything
82 1035683 49680 66648 29096 3680 urxvt --enable-everything
83
84 The very large size of the text section is explained by the
85 east-asian encoding tables, which, if unused, take up disk space but
86 nothing else and can be compiled out unless you rely on X11 core
87 fonts that use those encodings. The BSS size comes from the 64k
88 emergency buffer that my c++ compiler allocates (but of course
89 doesn't use unless you are out of memory). Also, using an xft font
90 instead of a core font immediately adds a few megabytes of RSS. Xft
91 indeed is responsible for a lot of RSS even when not used.
92
93 Of course, due to every character using two or four bytes instead of
94 one, a large scrollback buffer will ultimately make rxvt-unicode use
95 more memory.
96
97 Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k),
98 this still fares rather well. And compared to some monsters like
99 gnome-terminal (21152k + extra 4204k in separate processes) or
100 konsole (22200k + extra 43180k in daemons that stay around after
101 exit, plus half a minute of startup time, including the hundreds of
102 warnings it spits out), it fares extremely well *g*.
103
104 Why C++, isn't that unportable/bloated/uncool?
105 Is this a question? :) It comes up very often. The simple answer is:
106 I had to write it, and C++ allowed me to write and maintain it in a
107 fraction of the time and effort (which is a scarce resource for me).
108 Put even shorter: It simply wouldn't exist without C++.
109
110 My personal stance on this is that C++ is less portable than C, but
111 in the case of rxvt-unicode this hardly matters, as its portability
112 limits are defined by things like X11, pseudo terminals, locale
113 support and unix domain sockets, which are all less portable than
114 C++ itself.
115
116 Regarding the bloat, see the above question: It's easy to write
117 programs in C that use gobs of memory, an certainly possible to
118 write programs in C++ that don't. C++ also often comes with large
119 libraries, but this is not necessarily the case with GCC. Here is
120 what rxvt links against on my system with a minimal config:
121
122 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
123 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
124 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
125 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
126
127 And here is rxvt-unicode:
128
129 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
130 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
131 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
132 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
133 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
134
135 No large bloated libraries (of course, none were linked in
136 statically), except maybe libX11 :)
137
138 Does it support tabs, can I have a tabbed rxvt-unicode?
139 rxvt-unicode does not directly support tabs. It will work fine with
140 tabbing functionality of many window managers or similar tabbing
141 programs, and its embedding-features allow it to be embedded into
142 other programs, as witnessed by doc/rxvt-tabbed or the upcoming
143 "Gtk2::URxvt" perl module, which features a tabbed urxvt (murxvt)
144 terminal as an example embedding application.

40 other users that might encounter the same issue. 165 other users that might encounter the same issue.
166
167 I am maintaining rxvt-unicode for distribution/OS XXX, any
168 recommendation?
169 You should build one binary with the default options. configure now
170 enables most useful options, and the trend goes to making them
171 runtime-switchable, too, so there is usually no drawback to enbaling
172 them, except higher disk and possibly memory usage. The perl
173 interpreter should be enabled, as important functionality (menus,
174 selection, likely more in the future) depends on it.
175
176 You should not overwrite the "perl-ext-common" snd "perl-ext"
177 resources system-wide (except maybe with "defaults"). This will
178 result in useful behaviour. If your distribution aims at low memory,
179 add an empty "perl-ext-common" resource to the app-defaults file.
180 This will keep the perl interpreter disabled until the user enables
181 it.
182
183 If you can/want build more binaries, I recommend building a minimal
184 one with "--disable-everything" (very useful) and a maximal one with
185 "--enable-everything" (less useful, it will be very big due to a lot
186 of encodings built-in that increase download times and are rarely
187 used).
188
189 I need to make it setuid/setgid to support utmp/ptys on my OS, is this
190 safe?
191 It should be, starting with release 7.1. You are encouraged to
192 properly install urxvt with privileges necessary for your OS now.
193
194 When rxvt-unicode detects that it runs setuid or setgid, it will
195 fork into a helper process for privileged operations (pty handling
196 on some systems, utmp/wtmp/lastlog handling on others) and drop
197 privileges immediately. This is much safer than most other terminals
198 that keep privileges while running (but is more relevant to urxvt,
199 as it contains things as perl interpreters, which might be "helpful"
200 to attackers).
201
202 This forking is done as the very first within main(), which is very
203 early and reduces possible bugs to initialisation code run before
204 main(), or things like the dynamic loader of your system, which
205 should result in very little risk.

510 longer supported (and makes no sense, either, as it only supported a
511 single font). I recommend starting the X-server in "-multiwindow" or
512 "-rootless" mode instead, which will result in similar look&feel as
513 the old libW11 emulation.
514
515 At the time of this writing, cygwin didn't seem to support any
516 multi-byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are

610 Rxvt-unicode crashes when the X Input Method changes or exits.
611 Unfortunately, this is unavoidable, as the XIM protocol is racy by
612 design. Applications can avoid some crashes at the expense of memory
613 leaks, and Input Methods can avoid some crashes by careful ordering
614 at exit time. kinput2 (and derived input methods) generally
615 succeeds, while SCIM (or similar input methods) fails. In the end,
616 however, crashes cannot be completely avoided even if both sides
617 cooperate.
618
619 So the only workaround is not to kill your Input Method Servers.

1165menuBar
1166 The exact syntax used is *almost* solidified. In the menus, DON'T try to
1167 use menuBar commands that add or remove a menuBar.
1168
1169 Note that in all of the commands, the */path/* *cannot* be omitted: use
1170 ./ to specify a menu relative to the current menu.
1171
1172 Overview of menuBar operation
1173 For the menuBar XTerm escape sequence "ESC ] 703 ; Pt ST", the syntax of
1174 "Pt" can be used for a variety of tasks:
1175
1176 At the top level is the current menuBar which is a member of a circular
1177 linked-list of other such menuBars.
1178
1179 The menuBar acts as a parent for the various drop-down menus, which in
1180 turn, may have labels, separator lines, menuItems and subMenus.
1181
1182 The menuItems are the useful bits: you can use them to mimic keyboard
1183 input or even to send text or escape sequences back to rxvt.
1184
1185 The menuBar syntax is intended to provide a simple yet robust method of
1186 constructing and manipulating menus and navigating through the menuBars.
1187
1188 The first step is to use the tag [menu:*name*] which creates the menuBar
1189 called *name* and allows access. You may now or menus, subMenus, and
1190 menuItems. Finally, use the tag [done] to set the menuBar access as
1191 readonly to prevent accidental corruption of the menus. To re-access the
1192 current menuBar for alterations, use the tag [menu], make the
1193 alterations and then use [done]
1194
1195
1196
1197 Commands
1198 [menu:+*name*]
1199 access the named menuBar for creation or alteration. If a new
1200 menuBar is created, it is called *name* (max of 15 chars) and the
1201 current menuBar is pushed onto the stack
1202
1203 [menu]
1204 access the current menuBar for alteration
1205
1206 [title:+*string*]
1207 set the current menuBar's title to *string*, which may contain the
1208 following format specifiers: %% : literal % character %n : rxvt name
1209 (as per the -name command-line option) %v : rxvt version
1210
1211 [done]
1212 set menuBar access as readonly. End-of-file tag for [read:+*file*]
1213 operations.
1214
1215 [read:+*file*]
1216 read menu commands directly from *file* (extension ".menu" will be
1217 appended if required.) Start reading at a line with [menu] or
1218 [menu:+*name* and continuing until [done] is encountered.
1219
1220 Blank and comment lines (starting with #) are ignored. Actually,
1221 since any invalid menu commands are also ignored, almost anything
1222 could be construed as a comment line, but this may be tightened up
1223 in the future ... so don't count on it!.
1224
1225 [read:+*file*;+*name*]
1226 The same as [read:+*file*], but start reading at a line with
1227 [menu:+*name*] and continuing until [done:+*name*] or [done] is
1228 encountered.
1229
1230 [dump]
1231 dump all menuBars to the file /tmp/rxvt-PID in a format suitable for
1232 later rereading.
1233
1234 [rm:name]
1235 remove the named menuBar
1236
1237 [rm] [rm:]
1238 remove the current menuBar
1239
1240 [rm*] [rm:*]
1241 remove all menuBars
1242
1243 [swap]
1244 swap the top two menuBars
1245
1246 [prev]
1247 access the previous menuBar
1248
1249 [next]
1250 access the next menuBar
1251
1252 [show]
1253 Enable display of the menuBar
1254
1255 [hide]
1256 Disable display of the menuBar
1257
1258 [pixmap:+*name*]
1259 [pixmap:+*name*;*scaling*]
1260 (set the background pixmap globally
1261
1262 A Future implementation *may* make this local to the menubar)
1263
1264 [:+*command*:]
1265 ignore the menu readonly status and issue a *command* to or a menu
1266 or menuitem or change the ; a useful shortcut for setting the quick
1267 arrows from a menuBar.
1268
1269
1270
1271 Adding and accessing menus
1272 The following commands may also be + prefixed.
1273
1274 /+ access menuBar top level
1275
1276 ./+ access current menu level
1277
1278 ../+
1279 access parent menu (1 level up)
1280
1281 ../../
1282 access parent menu (multiple levels up)
1283
1284 */path/*menu
1285 add/access menu
1286
1287 */path/*menu/*
1288 add/access menu and clear it if it exists
1289
1290 */path/*{-}
1291 add separator
1292
1293 */path/*{item}
1294 add item as a label
1295
1296 */path/*{item} action
1297 add/alter *menuitem* with an associated *action*
1298
1299 */path/*{item}{right-text}
1300 add/alter *menuitem* with right-text as the right-justified text and
1301 as the associated *action*
1302
1303 */path/*{item}{rtext} action
1304 add/alter *menuitem* with an associated *action* and with rtext as
1305 the right-justified text.
1306
1307 Special characters in *action* must be backslash-escaped:
1308 \a \b \E \e \n \r \t \octal
1309
1310 or in control-character notation:
1311 ^@, ^A .. ^Z .. ^_, ^?
1312
1313 To send a string starting with a NUL (^@) character to the program,
1314 start *action* with a pair of NUL characters (^@^@), the first of which
1315 will be stripped off and the balance directed to the program. Otherwise
1316 if *action* begins with NUL followed by non-+NUL characters, the leading
1317 NUL is stripped off and the balance is sent back to rxvt.
1318
1319 As a convenience for the many Emacs-type editors, *action* may start
1320 with M- (eg, M-$ is equivalent to \E$) and a CR will be appended if
1321 missed from M-x commands.
1322
1323 As a convenience for issuing XTerm ESC ] sequences from a menubar (or
1324 quick arrow), a BEL (^G) will be appended if needed.
1325
1326 For example,
1327 M-xapropos is equivalent to \Exapropos\r
1328
1329 and \E]703;mona;100 is equivalent to \E]703;mona;100\a
1330
1331 The option {*right-rtext*} will be right-justified. In the absence of a
1332 specified action, this text will be used as the *action* as well.
1333
1334 For example,
1335 /File/{Open}{^X^F} is equivalent to /File/{Open}{^X^F} ^X^F
1336
1337 The left label *is* necessary, since it's used for matching, but
1338 implicitly hiding the left label (by using same name for both left and
1339 right labels), or explicitly hiding the left label (by preceeding it
1340 with a dot), makes it possible to have right-justified text only.
1341
1342 For example,
1343 /File/{Open}{Open} Open-File-Action
1344
1345 or hiding it
1346 /File/{.anylabel}{Open} Open-File-Action
1347
1348

1361 remove separator)
1362
1363 -/path/menu/*
1364 remove all items, separators and submenus from menu
1365
1366
1367
1368 Quick Arrows
1369 The menus also provide a hook for *quick arrows* to provide easier user
1370 access. If nothing has been explicitly set, the default is to emulate
1371 the curror keys. The syntax permits each arrow to be altered
1372 individually or all four at once without re-entering their common
1373 beginning/end text. For example, to explicitly associate cursor actions
1374 with the arrows, any of the following forms could be used:
1375
1376 <r>+*Right*
1377 <l>+*Left*
1378 <u>+*Up*
1379 <d>+*Down*
1380 Define actions for the respective arrow buttons
1381
1382 <b>+*Begin*
1383 <e>+*End*
1384 Define common beginning/end parts for *quick arrows* which used in
1385 conjunction with the above <r> <l> <u> <d> constructs
1386
1387 For example, define arrows individually,
1388 <u>\E[A
1389
1390 <d>\E[B
1391
1392 <r>\E[C
1393
1394 <l>\E[D
1395
1396 or all at once
1397 <u>\E[AZ<><d>\E[BZ<><r>\E[CZ<><l>\E[D
1398
1399 or more compactly (factoring out common parts)
