Ubuntu12.04 安装ibusfbterm0.9.1

Ubuntu12.04 安装ibus-fbterm-0.9.1

有没有朋友想在真正的终端（console)下显示并输入中文，我想肯定是有的，比如我自己就研究过好一阵，结果还初见成效，这里分享一点自己的小经验。
目前可行的方案有：
fbterm+ucimf            (简略粗糙)
fbterm+ibus-fbterm （通用)
fbterm+fcitx-fbterm   (最优方案)
fbterm+yong

这里就介绍最通用的一种，屡试不爽噢！

直接用ubuntu12.04的官方源安装基本组件

sudo  apt-get  install  fbterm  ibus ibus-table-wubi ibus-pinyin ibus-1.0 im-switch(im-config)  (galternatives)   #括号内的包是可能会用到

ibus-fbterm
wget    http://ibus-fbterm.googlecode.com/files/ibus-fbterm-0.9.1.tar.gz

tar   -zxvf   ibus-fbterm-0.9.1.tar.gz   -C   /usr/local/src
./configure 
make  &&  make install

64bit系统会出现一个bug，

display.c: 在函数‘calculate_status_win’中:
display.c:215:23: 错误： ‘IBusProperty’没有名为‘label’的成员
display.c: 在函数‘draw_status_bar’中:

上有高人朋友已经给出了解决办法。



Thannks for your reporting. I found out it is becase ibus upgrade its API, according to https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=771115. I already infomation the author to ask him to make a upgrade. And I do my little try, you may want to test it if you are really in harry. But I am not very sure whether I make it right.

************************************
Here is diff of display.c:
215,216c215
<
< w += text_width(ibus_property_get_label(prop)->text);
---
> w += text_width(prop->label->text);
242,244c241,242
< draw_text(x, y, COLOR_FG, COLOR_BG, ibus_property_get_label(prop)->text,
< strlen(ibus_property_get_label(prop)->text));
< x += FW(text_width(ibus_property_get_label(prop)->text));
---
> draw_text(x, y, COLOR_FG, COLOR_BG, prop->label->text, strlen(prop->label->text));
> x += FW(text_width(prop->label->text));
************************************

就是display.c文件中要改几个地方，改完后再编译就可顺利通过，以下是替换后的display.c

好的，在console下要开启fbterm和ibus-fbterm
Ctl+Alt+fx(x=1,2,3,4,5,6,7),如：Ctl+Alt+f2

输入用户名,密码后，键入以下命令
fbterm  -i   ibus-fbterm

由于fbterm使用的默认字体mono表现比较差,所以我为Linux安装了微软雅黑用于中文显示,Consolas用于英文显示(也可以使用Moncao,二者表现都不错,但是个人认为Consolas表现柔和,很适合作为编程字体).
(1). 安装微软雅黑:
a. 从Windows 7或XP中复制msyh.ttf和msyhbd.ttf到Linux字体目录
"/usr/share/fonts/truetype/msttcorefonts"中,并将两个文件权限修改为777,也可以修改为644,再创建两个软连接,如:
ln -s msyh.ttf Msyh.ttf
ln -s msyhbd.ttf Msyhbd.ttf
b. 接着使用如下命令注册字体:
mkfontscale
mkfontdir
fc-cache  -fv

(2). Consolas也是Windows下的字体,其安装过程与微软雅黑一样,只是
该字体需到网上下载,下载地址如下(这是雅黑和Consolas的结合体,字体名称为"YaHei Consolas Hybrid"):
http://files.xiaogui.org/eclipse-indigo/YaHei.Consolas.1.12.rar


(3). Monaco本来为Mac系统上的字体,不过现在已经有Linux下的版本了,
故只需下载并将其放到字体目录即可,也没了上面的麻烦了.
下载地址:http://www.gringod.com/wp-upload/software/Fonts/Monaco_Linux.ttf


5. 修改fbterm的默认字体,编辑其配置文件"~/.fbtermrc",修改font-names的
值为"Consolas,Monaco,微软雅黑",并将字体font-size调大至15,这就看个人爱好了.

fbterm的更多自定义设置可以在～/.fbtemrc中指定，配置文件的意思一看便懂，这里就不絮叨了。
以下是我个人的一个样例：
# Configuration for FbTerm

# Lines starting with '#' are ignored.
# Note that end-of-line comments are NOT supported, comments must be on a line of their own.


# font family names/pixelsize used by fbterm, multiple font family names must be seperated by ','
# and using a fixed width font as the first is strongly recommended
font-names=mono
font-size=15

# force font width (and/or height), usually for non-fixed width fonts
# legal value format: n (fw_new = n), +n (fw_new = fw_old + n), -n (fw_new = fw_old - n)
#font-width=
#font-height=

# default color of foreground/background text
# available colors: 0 = black, 1 = red, 2 = green, 3 = brown, 4 = blue, 5 = magenta, 6 = cyan, 7 = white
color-foreground=7
color-background=0

# max scroll-back history lines of every window, value must be [0 - 65535], 0 means disable it
history-lines=100

# up to 5 additional text encodings, multiple encodings must be seperated by ','
# run 'iconv --list' to get available encodings.
text-encodings=zh_CN.UTF-8,en_US.UTF-8,GB2312,GB18030,GBK

# cursor shape: 0 = underline, 1 = block
# cursor flash interval in milliseconds, 0 means disable flashing
cursor-shape=0
cursor-interval=500

# additional ascii chars considered as part of a word while auto-selecting text, except ' ', 0-9, a-z, A-Z
word-chars=._-

# change the clockwise orientation angle of screen display
# available values: 0 = 0 degree, 1 = 90 degrees, 2 = 180 degrees, 3 = 270 degrees
screen-rotate=0

# specify the favorite input method program to run
input-method=/usr/local/bin/-fbterm

# treat ambiguous width characters as wide
ambiguous-wide=yes
