ArchLinux的gvim版本比较新，
但是其python2的library链接有错。
当import gtk就会出现Error import的错误提示。

这个错误我知道已经有好几个月了，
之前在github上就有用ArchLinux的人表示用不了我插件里的取色器。
但是当时我用的还是Ubuntu，所以没去fix。

不过如今我用上了Arch,当然得解决这个问题:D

方法很简单,重新编译gvim：

hg clone https://vim.googlecode.com/hg/ vim

cd vim/src
./configure --enable-multibyte --with-features=huge --enable-gui=gtk2 \
  --enable-python3interp=yes --enable-rubyinterp \
  --enable-pythoninterp=yes \
  --enable-tclinterp  --enable-fontset  \
  --with-python-config-dir=/usr/lib/python2.7/config \
  --with-python3-config-dir=/usr/lib/python3.2/config-3.2mu

make && sudo make install

NOTE：
1.要将python2 link 为 python，否则会提示找不到python2.x
在/usr/bin下
    ln -s python2 python
PS：安装好后可以用 ln -sf python3 python 把它替换回来

2.--with-python3-config-dir为/usr/lib/python3.2/config-3.2mu

3.如果还是找不到python2,可以在 auto/config.cache里找到
vi_cv_var_python_version并将此行改成
vi_cv_var_python_version=${vi_cv_var_python_version=2.7}

 

PS: 看了下gvim的PKGBUILD。里面有这么一句

  # fix python name
  sed -i -e 's|vi_cv_path_python, python|vi_cv_path_python, python2|' \
    vim-build/src/configure.in

那改这句应该也行。

也就是在configure.in里面把

vi_cv_path_python, python 改成 vi_cv_path_python, python2

在目前的主流浏览器里面，都可以撤销最后关闭的标签页。

于是我以为vim里面也有这样的功能，但是看完:help buffer后发现,这个真没有 :|

于是只好自己动手，写了个mapping

<ctrl-w>z:撤销最后关闭的buffer
 

"reopen last closed buffers "{{{
"exclude the buffer closed with :bw :qall :)
aug BufList
    au!
    au vimenter * let g:bufList=[]
    au bufwinleave * call AddBufList()
aug END
nmap <silent> <c-w>z :call OpenBufList()<cr>
nmap <silent> <c-w><c-z> <c-w>z
function! AddBufList()
    let b=expand('<abuf>')
    if b > 0
        let g:bufList=add(g:bufList,b)
    endif
endfunction
function! OpenBufList()
    if len(g:bufList) !=0
        exec "sb ".remove(g:bufList,-1)
    endif
endfunction "}}}

可以撤销:q :hid :close :only :bun :bd所关闭的buffer('hidden'选项没影响)

不会撤销 :bw :qall 所关闭的buffer

我猜也不需要撤销了吧，嗯……

 

---

NOTE:

1.<afile>是当前autocommand执行的对象,<abuf>是其buf number。不一定与“%”相同

还有一个<amatch>，看说明是指 filetype/syntax 的events时所匹配的filetype/syntax的名称

2.buffer events的执行顺序 ，'[]'括号内为'hidden'选项打开的情况。


:new => bufleave

:hid => bufleave -> bufwinleave -> bufhidden
(与:e #相同，'hidden'打开时:q,:close与之相同)

:bun => bufleave -> bufwinleave ->[bufhidden ->]bufunload
('hidden'关闭时:q,:close与之相同)

:bd  => bufleave -> bufwinleave ->[bufhidden ->]bufunload -> bufdelete

:bw  => bufleave -> bufwinleave ->[bufhidden ->]bufunload -> bufdelete
                 -> bufwipeout
                (!这里的buffer不能被恢复了)

 

 

I have installed archlinux with gnome-shell and replacing ubuntu11.10 due to gvim's python issues for a couple days.

As I have tried them both. here is my Yet Another Compare between gnome-shell and unity.

Looking:
    Gnome-shell is cleaner at first glance. but you can make unity with that
looking.
    the notification and tray applet of gnome-shell is better than unity.
    gnome-shell is a bit stylized than unity which need a bit config with
compiz

Usablity:
    They both introduce a quick way of opening applications: Activites and
Dash.
    gnome-shell combine window ,desktop and applications in Activites which
looks cleaner.
    unity don't have window in dash. and you could config expo/scales with ccsm
to have similar using as gnome-shell does.
    And both works fine with easystroke. that's enough for me.
    
Configurability:
    gnome-shell have no config tool. only a install tool with gnome-tweak-tool
and gnome-shell-extension
    unity configs in ccsm. but not fully configured.
    
Stability:
    unity is stable enough. and it can automatic recover after crashes most of
the time. you can use unity --replace to recover it manually.
    gnome-shell (3.2.1) crashes more often. and should recover it manually.
    by gnome-shell --replace
    or DISPLAY=:0 gnome-shell --replace & in other tty
    and sometimes you can't react with the windows even with gnome-shell
recovered.
 
Conclusion:
    unity is easy enough to use and need some time to config.
    gnome-shell is elegant but need some time to get used to (it's
crash).

 

Ubuntu 11.10升级好了，十分顺利，比10.10升11.04的时候好多了。

安装后桌面主题变了，需要自行设置。

Theme:Elegant_Brit
http://grvrulz.deviantart.com/art/Elegant-Brit-gnome3-208925032
下载后解压到~/.themes
不过panel面板居然是black,需要自己修改下
vim ~/.themes/Elegant_Brit/gtk-3.0/gtk.css
    @define-color os_chrome_bg_color black;
修改成自己想要的颜色就行了。

Icon:Faenza
http://tiheum.deviantart.com/art/Faenza-Icons-173323228

Theme和Icon设置
sudo apt-get install gnome-tweak-tool
运行后在theme里修改相应选项就行了
    
 

直接通过command line 似乎有bug.只能通过dbus

import dbus,sys,subprocess
import commands
bus = dbus.SessionBus()
banshee = bus.get_object ("org.bansheeproject.Banshee", "/org/bansheeproject/Banshee/PlayerEngine")
engine_interface=dbus.Interface (banshee, "org.bansheeproject.Banshee.PlayerEngine")
album=engine_interface.GetCurrentTrack()['album']
artist=engine_interface.GetCurrentTrack()['artist']
title=engine_interface.GetCurrentTrack()['name']

if len(sys.argv) == 2: 
    engine_interface.SetRating (dbus.Byte (int(sys.argv[1])))
    subprocess.call(["notify-send","Rate to: "+str(sys.argv[1]),artist+"\n"+title])
    
else:
    subprocess.call(["notify-send","Rate to: 0",artist+"\n"+title])
    engine_interface.SetRating (dbus.Byte (0))

使用:

>python bansheerating.py [1/2/3/4/5]

我是直接用easystroke的手势来运行的。

 

 

 

 

都是英文，改天再翻译，总之，就是个根据色彩自动生成主题的插件。支持Terminal(8/16/256)

Terminal curosr 部分感谢 依云同学的 改变终端下的光标颜色，包括 screen 和 tmux！

galaxy 在  http://www.vim.org/scripts/script.php?script_id=3729 下载

需要安装 ColorV http://www.vim.org/scripts/script.php?script_id=3597

    Where to start:     
        :colorscheme galaxy
        :Galaxy

##INSTALL##

1.Using [Vundle.vim](Recommend):~
    https://github.com/gmarik/vundle
    After installed vundle and git. Add this line to your vimrc  
    `Bundle 'Rykka/vim-galaxy'`
    `Bundle 'Rykka/ColorV'`
    Run `:BundleInstall` to install.
    And update them easily by `:BundleInstall!`
 
2.Using [Galaxy on Vim.org]~
    You should download latest 'ColorV' at first.
    http://www.vim.org/scripts/script.php?script_id=3597
    http://www.vim.org/scripts/script.php?script_id=3729
    Download the latest version of tar.gz file,
    Extract to $VIMFILE folder.
    ("~/.vim" for linux. "$HOME/vimfiles" for windows)
    Generate helptags. `:helptags ~/.vim/doc
 

一直以来，http://www.python.org/ 的download 页面都是被gfwed掉的。

 

今天上去下载，发现页面左边居然多了一个链接。

http://www.python.org/getit/

并且用中文写着“下载”。

 

当时我就感动了.... 多么理解中国国情的python开发者啊。

vim 下的\s 和python 的\s 不同

python 的\s 是[ \t\n\r\f\v]

vim 的 \s 是[ \t ]

 

这是我的一个vim插件，方便在vim中直接处理色彩文本（e.g.,yellow/rgb(255,255,0)/#ff3300）。

功能简述：
        选择颜色
        获取色彩信息
        改变色彩文本
        生成色彩列表
        预览色彩文本
 

最新版可以从 https://github.com/rykka/ColorV 下载

2.5版本的新特性

1. 采用了python 对核心程序重写.改变了原先的算法。

使运行速度得到极大提升

（gui <0.06s term<0.10s 对比之前的数据 gui~0.4s term~1.1s ）

 

2. 增加了新的max模式 ('<leader>cx')。

显示更多的色彩信息(RGB/HSV/HLS/YIQ)

一个色彩历史条，记录曾经复制过的色彩。

 

3.新的色彩空间

增加了一个HLS空间的显示 。"g:ColorV_win_space" 。

不过感觉用'hls'空间里面选择色彩并不比'hsv'方便。

 

4.终端支持(感谢依云同学)

添加了对彩色终端的支持。包括8/16/256色。

需要注意设置‘&t_Co’选项

 

附图

（左边是terminal 右边是gui。

其主题色彩是根据在colorv中所显示的色彩自动生成的。

生成器是我的另外一个插件vim-galaxy ，不过还没正式发布,哈哈）

 

 

 

 

 

 

 

 

 

 

 

 

 

上面是终端色图

左边delta_e_cie2000,右边是rgb差值

下面为标准色图

可看出，其差别主要是在饱和度和亮度较低(<40)时，rgb算法就丢失了色彩信息

而delta_e_cie2000在(<25)左右丢失

总体上delta_e_cie2000比rgb更鲜艳。

不过就识别度而言，两者都差不多。

用rgb差值还是能够接受的
