23 | Isn't rxvt supposed to be small? Don't all those features bloat? |
|
|
24 | I often get asked about this, and I think, no, they didn't cause |
|
|
25 | extra bloat. If you compare a minimal rxvt and a minimal urxvt, you |
|
|
26 | can see that the urxvt binary is larger (due to some encoding tables |
|
|
27 | always being compiled in), but it actually uses less memory (RSS) |
|
|
28 | after startup. Even with "--disable-everything", this comparison is |
|
|
29 | a bit unfair, as many features unique to urxvt (locale, encoding |
|
|
30 | conversion, iso14755 etc.) are already in use in this mode. |

|
|
35 | |
|
|
36 | When you "--enable-everything" (which _is_ unfair, as this involves |
|
|
37 | xft and full locale/XIM support which are quite bloaty inside libX11 |
|
|
38 | and my libc), the two diverge, but not unreasnobaly so. |

|
|
43 | |
|
|
44 | The very large size of the text section is explained by the |
|
|
45 | east-asian encoding tables, which, if unused, take up disk space but |
|
|
46 | nothing else and can be compiled out unless you rely on X11 core |
|
|
47 | fonts that use those encodings. The BSS size comes from the 64k |
|
|
48 | emergency buffer that my c++ compiler allocates (but of course |
|
|
49 | doesn't use unless you are out of memory). Also, using an xft font |
|
|
50 | instead of a core font immediately adds a few megabytes of RSS. Xft |
|
|
51 | indeed is responsible for a lot of RSS even when not used. |
|
|
52 | |
|
|
53 | Of course, due to every character using two or four bytes instead of |
|
|
54 | one, a large scrollback buffer will ultimately make rxvt-unicode use |
|
|
55 | more memory. |
|
|
56 | |
|
|
57 | Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), |
|
|
58 | this still fares rather well. And compared to some monsters like |
|
|
59 | gnome-terminal (21152k + extra 4204k in separate processes) or |
|
|
60 | konsole (22200k + extra 43180k in daemons that stay around after |
|
|
61 | exit, plus half aminute of startup time, including the hundreds of |
|
|
62 | warnings it spits out), it fares extremely well *g*. |
|
|
63 | |
|
|
64 | Why C++, isn't that unportable/bloated/uncool? |
|
|
65 | Is this a question? :) It comes up very often. The simple answer is: |
|
|
66 | I had to write it, and C++ allowed me to write and maintain it in a |
|
|
67 | fraction of the time and effort (which is a scarce resource for me). |
|
|
68 | Put even shorter: It simply wouldn't exist without C++. |
|
|
69 | |
|
|
70 | My personal stance on this is that C++ is less portable than C, but |
|
|
71 | in the case of rxvt-unicode this hardly matters, as its portability |
|
|
72 | limits are defined by things like X11, pseudo terminals, locale |
|
|
73 | support and unix domain sockets, which are all less portable than |
|
|
74 | C++ itself. |
|
|
75 | |
|
|
76 | Regarding the bloat, see the above question: It's easy to write |
|
|
77 | programs in C that use gobs of memory, an certainly possible to |
|
|
78 | write programs in C++ that don't. C++ also often comes with large |
|
|
79 | libraries, but this is not necessarily the case with GCC. Here is |
|
|
80 | what rxvt links against on my system with a minimal config: |
|
|
81 | |
|
|
82 | libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) |
|
|
83 | libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000) |
|
|
84 | libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000) |
|
|
85 | /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) |
|
|
86 | |
|
|
87 | And here is rxvt-unicode: |
|
|
88 | |
|
|
89 | libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) |
|
|
90 | libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000) |
|
|
91 | libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000) |
|
|
92 | libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000) |
|
|
93 | /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) |
|
|
94 | |
|
|
95 | No large bloated libraries (of course, none were linked in |
|
|
96 | statically), except maybe libX11 :) |

98 | Does it support tabs, can I have a tabbed rxvt-unicode? |
|
|
99 | rxvt-unicode does not directly support tabs. It will work fine with |
|
|
100 | tabbing functionality of many window managers or similar tabbing |
|
|
101 | programs, and its embedding-features allow it to be embedded into |
|
|
102 | other programs, as witnessed by doc/rxvt-tabbed or the upcoming |
|
|
103 | "Gtk2::URxvt" perl module, which features a tabbed urxvt (murxvt) |
|
|
104 | terminal as an example embedding application. |
