71 root 1.43 Yes. For example, if you want to select alphanumeric words, you can use
72     the following resource:
73 root 1.42 </dd>
74     <dd>

83     <p>To get a selection that is very similar to the old code, try this pattern:</p>

88     </dd>
89 root 1.43 <dd>
90     <p>Please also note that the <em>LeftClick Shift-LeftClik</em> combination also
91     selects words like the old code.</p>

95     change/disable it?</a></strong><br />
96     </dt>
97     <dd>
98     You can disable the perl extension completely by setting the
99     <strong>perl-ext-common</strong> resource to the empty string, which also keeps
100     rxvt-unicode from initialising perl, saving memory.
101     </dd>
102     <dd>
103     <p>If you only want to disable specific features, you first have to
104     identify which perl extension is responsible. For this, read the section
105 root 1.45 <strong>PREPACKAGED EXTENSIONS</strong> in the <code>rxvtperl(3)</code> manpage. For
106 root 1.41 example, to disable the <strong>selection-popup</strong> and <strong>option-popup</strong>, specify
107     this <strong>perl-ext-common</strong> resource:</p>
108     </dd>
109     <dd>
110     <pre>
111     URxvt.perl-ext-common: default,-selection-popup,-option-popup</pre>
112     </dd>
113     <dd>
114     <p>This will keep the default extensions, but disable the two popup
115     extensions. Some extensions can also be configured, for example,
116     scrollback search mode is triggered by <strong>M-s</strong>. You can move it to any
117     other combination either by setting the <strong>searchable-scrollback</strong> resource:</p>
118     </dd>
119     <dd>
120     <pre>
121     URxvt.searchable-scrollback: CM-s</pre>
122     </dd>
123     <p></p>
124 root 1.28 <dt><strong><a name="item_isn_27t_rxvt_supposed_to_be_small_3f_don_27t_all_t">Isn't rxvt supposed to be small? Don't all those features bloat?</a></strong><br />
125     </dt>
126     <dd>
127     I often get asked about this, and I think, no, they didn't cause extra
128     bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
129     that the urxvt binary is larger (due to some encoding tables always being
130     compiled in), but it actually uses less memory (RSS) after startup. Even
131     with <code>--disable-everything</code>, this comparison is a bit unfair, as many
132     features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
133     already in use in this mode.
134     </dd>

139     188985 9048 66616 18222 1788 urxvt --disable-everything</pre>
140     </dd>
141     <dd>
142     <p>When you <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (which _is_ unfair, as this involves xft
143     and full locale/XIM support which are quite bloaty inside libX11 and my
144     libc), the two diverge, but not unreasnobaly so.</p>
145     </dd>
146     <dd>
147     <pre>
148     text data bss drs rss filename
149     163431 2152 24 20123 2060 rxvt --enable-everything
150     1035683 49680 66648 29096 3680 urxvt --enable-everything</pre>
151     </dd>
152     <dd>
153     <p>The very large size of the text section is explained by the east-asian
154     encoding tables, which, if unused, take up disk space but nothing else
155     and can be compiled out unless you rely on X11 core fonts that use those
156     encodings. The BSS size comes from the 64k emergency buffer that my c++
157     compiler allocates (but of course doesn't use unless you are out of
158     memory). Also, using an xft font instead of a core font immediately adds a
159     few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
160     not used.</p>
161     </dd>
162     <dd>
163     <p>Of course, due to every character using two or four bytes instead of one,
164     a large scrollback buffer will ultimately make rxvt-unicode use more
165     memory.</p>
166     </dd>
167     <dd>
168     <p>Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
169     still fares rather well. And compared to some monsters like gnome-terminal
170     (21152k + extra 4204k in separate processes) or konsole (22200k + extra
171 root 1.37 43180k in daemons that stay around after exit, plus half a minute of
172 root 1.28 startup time, including the hundreds of warnings it spits out), it fares
173     extremely well *g*.</p>
174     </dd>

176     <dt><strong><a name="item_why_c_2b_2b_2c_isn_27t_that_unportable_2fbloated_2">Why C++, isn't that unportable/bloated/uncool?</a></strong><br />
177     </dt>
178     <dd>
179     Is this a question? :) It comes up very often. The simple answer is: I had
180     to write it, and C++ allowed me to write and maintain it in a fraction
181     of the time and effort (which is a scarce resource for me). Put even
182     shorter: It simply wouldn't exist without C++.
183     </dd>
184     <dd>
185     <p>My personal stance on this is that C++ is less portable than C, but in
186     the case of rxvt-unicode this hardly matters, as its portability limits
187     are defined by things like X11, pseudo terminals, locale support and unix
188     domain sockets, which are all less portable than C++ itself.</p>
189     </dd>
190     <dd>
191     <p>Regarding the bloat, see the above question: It's easy to write programs
192     in C that use gobs of memory, an certainly possible to write programs in
193     C++ that don't. C++ also often comes with large libraries, but this is
194     not necessarily the case with GCC. Here is what rxvt links against on my
195     system with a minimal config:</p>
196     </dd>

221     </dt>
222     <dd>
223     rxvt-unicode does not directly support tabs. It will work fine with
224     tabbing functionality of many window managers or similar tabbing programs,
225     and its embedding-features allow it to be embedded into other programs,
226     as witnessed by <em>doc/rxvt-tabbed</em> or the upcoming <code>Gtk2::URxvt</code> perl
227     module, which features a tabbed urxvt (murxvt) terminal as an example
228     embedding application.

232     </dt>
233     <dd>
234     The version number is displayed with the usage (-h). Also the escape
235 root 1.28 sequence <code>ESC [ 8 n</code> sets the window title to the version number. When
236 root 1.45 using the rxvtc client, the version displayed is that of the

241     </dt>
242     <dd>
243 root 1.21 The Debian GNU/Linux package of rxvt-unicode in sarge contains large
244     patches that considerably change the behaviour of rxvt-unicode. Before
245     reporting a bug to the original rxvt-unicode author please download and
246     install the genuine version (<a href="http://software.schmorp.de#rxvt-unicode">http://software.schmorp.de#rxvt-unicode</a>)
247     and try to reproduce the problem. If you cannot, chances are that the
248     problems are specific to Debian GNU/Linux, in which case it should be
249     reported via the Debian Bug Tracking System (use <code>reportbug</code> to report
250     the bug).
251 root 1.11 </dd>
252     <dd>
253     <p>For other problems that also affect the Debian package, you can and
254     probably should use the Debian BTS, too, because, after all, it's also a
255     bug in the Debian version and it serves as a reminder for other users that
256     might encounter the same issue.</p>
257 root 1.1 </dd>

259 root 1.36 <dt><strong><a name="item_i_am_maintaining_rxvt_2dunicode_for_distribution_2">I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?</a></strong><br />
260     </dt>
261     <dd>
262     You should build one binary with the default options. <em>configure</em>
263     now enables most useful options, and the trend goes to making them
264     runtime-switchable, too, so there is usually no drawback to enbaling them,
265     except higher disk and possibly memory usage. The perl interpreter should
266     be enabled, as important functionality (menus, selection, likely more in
267     the future) depends on it.
268     </dd>
269     <dd>
270     <p>You should not overwrite the <code>perl-ext-common</code> snd <code>perl-ext</code> resources
271     system-wide (except maybe with <code>defaults</code>). This will result in useful
272     behaviour. If your distribution aims at low memory, add an empty
273     <code>perl-ext-common</code> resource to the app-defaults file. This will keep the
274     perl interpreter disabled until the user enables it.</p>
275     </dd>
276     <dd>
277     <p>If you can/want build more binaries, I recommend building a minimal
278     one with <code>--disable-everything</code> (very useful) and a maximal one with
279     <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (less useful, it will be very big due to a lot of
280     encodings built-in that increase download times and are rarely used).</p>

284     </dt>
285     <dd>
286 root 1.48 It should be, starting with release 7.1. You are encouraged to properly
287     install urxvt with privileges necessary for your OS now.
288     </dd>
289     <dd>
290     <p>When rxvt-unicode detects that it runs setuid or setgid, it will fork
291     into a helper process for privileged operations (pty handling on some
292     systems, utmp/wtmp/lastlog handling on others) and drop privileges
293     immediately. This is much safer than most other terminals that keep
294     privileges while running (but is more relevant to urxvt, as it contains
295     things as perl interpreters, which might be ``helpful'' to attackers).</p>
296     </dd>
297     <dd>
298     <p>This forking is done as the very first within main(), which is very early
299     and reduces possible bugs to initialisation code run before main(), or
300     things like the dynamic loader of your system, which should result in very
301     little risk.</p>

306     <dd>
307     The terminal description used by rxvt-unicode is not as widely available
308     as that for xterm, or even rxvt (for which the same problem often arises).
309     </dd>
310     <dd>
311     <p>The correct solution for this problem is to install the terminfo, this can
312     be done like this (with ncurses' infocmp):</p>

319     <dd>
320     <p>... or by installing rxvt-unicode normally on the remote system,</p>
321     </dd>
322     <dd>
323     <p>If you cannot or do not want to do this, then you can simply set
324     <code>TERM=rxvt</code> or even <code>TERM=xterm</code>, and live with the small number of
325     problems arising, which includes wrong keymapping, less and different
326     colours and some refresh errors in fullscreen applications. It's a nice
327     quick-and-dirty workaround for rare cases, though.</p>
328     </dd>
329     <dd>
330 root 1.11 <p>If you always want to do this (and are fine with the consequences) you
331     can either recompile rxvt-unicode with the desired TERM value or use a

334     <dd>

355 root 1.11 One reason you might want this is that some distributions or operating
356     systems still compile some programs using the long-obsoleted termcap
357 root 1.14 library (Fedora Core's bash is one example) and rely on a termcap entry
358     for <code>rxvt-unicode</code>.

360     <dd>
361     <p>You could use rxvt's termcap entry with resonable results in many cases.

531     This is because there is a difference between script and language --
532 root 1.11 rxvt-unicode does not know which language the text that is output is,
533     as it only knows the unicode character codes. If rxvt-unicode first
534     sees a japanese/chinese character, it might choose a japanese font for
535     display. Subsequent japanese characters will use that font. Now, many
536     chinese characters aren't represented in japanese fonts, so when the first
537 root 1.1 non-japanese character comes up, rxvt-unicode will look for a chinese font
538     -- unfortunately at this point, it will still use the japanese font for
539 root 1.11 chinese characters that are also in the japanese font.
540 root 1.1 </dd>
541     <dd>
542     <p>The workaround is easy: just tag a chinese font at the end of your font

560     Most fonts were not designed for terminal use, which means that character
561     size varies a lot. A font that is otherwise fine for terminal use might
562     contain some characters that are simply too wide. Rxvt-unicode will avoid

567     <p>All of this requires that fonts do not lie about character sizes,

1135     snippets to correctly set the display. If your version of rxvt-unicode
1136     wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1137     the COLORTERM variable can be used to distinguish rxvt-unicode from a
1138     regular xterm.

2206     for Xft fonts, although having them compiled in lets rxvt-unicode choose
2207     replacement fonts more intelligently. Compiling them in will make your
