git commit 風格建議

紀錄sublime 3 裝了啥

首先裝
packagecontrol:

https://packagecontrol.io/installation


 command + shift + p 找安裝套件


安裝alignment

Preferences > Packages Settings > Alignment > Settings - User
加入以下內容：

{
    // The mid-line characters to align in a multi-line selection, changing
    // this to an empty array will disable mid-line alignment
    "alignment_chars": [
        "=", ":"
    ],
    "alignment_space_chars": ["="],
    "alignment_prefix_chars": [
"+", "-", "&", "|", "<", ">", "!", "~", "%", "/", "*", "."
]

}



之後選取要alignment的內容
command + ctl + a



安裝git

安裝SideBarEnhancements



下載Vinageous


啟用vim模式
Preference->Setting-User 打開編輯，將ignored_packages裡面的[]清空
"ignored_packages":
　[
　]


我的主要配置 Preferences -> Settings -> User

{ "color_scheme": "Packages/User/SublimeLinter/Monokai (SL).tmTheme", "highlight_line": true, "ignored_packages": [ "Vintage" ], "vintageous_use_ctrl_keys": true, "vintageous_use_sys_clipboard": true
}

方便我切換其tab:

修改Preferences -> Key Bindings -> User

[
{ "keys": ["super+left"], "command": "prev_view" },
{ "keys": ["super+right"], "command": "next_view" },
{ "keys": ["super+t"], "command": "new_file" },
]

參考mac os X 上sublime 的配置：

http://guoqiao.me/post/2015/0110-sublime-text-config-for-mac-os-x

我的keymap 長這樣：

[
{ "keys": ["super+left"], "command": "prev_view" },
{ "keys": ["super+right"], "command": "next_view" },
{ "keys": ["super+t"], "command": "new_file" },
{
"keys": ["super+alt+right"],
"command": "set_layout",
"args":
{
"cols": [0.0, 0.33, 1.0],
"rows": [0.0, 1.0],
"cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
}
},
{
"keys": ["super+alt+left"],
"command": "set_layout",
"args":
{
"cols": [0.0, 0.66, 1.0],
"rows": [0.0, 1.0],
"cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
}
},
{ "keys": ["alt+1"], "command": "move_to_group", "args": { "group": 0 } },
{ "keys": ["alt+2"], "command": "move_to_group", "args": { "group": 1 } },
{ "keys": ["alt+3"], "command": "move_to_group", "args": { "group": 2 } },
{ "keys": ["alt+4"], "command": "move_to_group", "args": { "group": 3 } },
{ "keys": ["alt+5"], "command": "move_to_group", "args": { "group": 4 } },
{ "keys": ["alt+6"], "command": "move_to_group", "args": { "group": 5 } },
{ "keys": ["alt+7"], "command": "move_to_group", "args": { "group": 6 } },
{ "keys": ["alt+8"], "command": "move_to_group", "args": { "group": 7 } },
{ "keys": ["alt+9"], "command": "move_to_group", "args": { "group": 8 } },
{ "keys": ["f1"], "command": "clone_file_and_move_to_group" }

]

我想要一個功能類似vim 裡面的:split

1) Tools → New Plugin

import sublime
import sublime_plugin

class CloneFileAndMoveToGroup(sublime_plugin.WindowCommand):
    def run(self):
        self.window.run_command("clone_file")
#        self.window.run_command("move_to_group", { "group": 1 })
        self.window.run_command("move_to_neighboring_group")

2) Sublime Text 2 → Preferences → Key Bindings — User

{ "keys": ["f1"], "command": "clone_file_and_move_to_group" }

Add SSH key to GitLab

ssh-keygen -t rsa -C "xxx@gmail.com"

copy完貼到gitlab

github 常用指令

基礎的：

生patch：

 git diff  branchname --cached > patch

http://blog.csdn.net/maybe_windleave/article/details/8703778

Push changes from your commit into your branch :

$ git push origin [name_of_your_remote]

刪除遠端 branch:

git push origin :your_branch

刪除本地branch:

git branch -d yourbranch

update remote branch:
http://blog.csdn.net/u012150179/article/details/17172211


2 ,从远程获取最新版本到本地


1
2
3
4


$ git fetch origin master
From https://github.com/com360/android-app
 * branch            master     -> FETCH_HEAD
su@SUCHANGLI /e/eoe_client/android-app (master)





$ git fetch origin master 这句的意思是：从远程的origin仓库的master分支下载代码到本地的origin master
3. 比较本地的仓库和远程参考的区别


1
2


$ git log -p master.. origin/master
su@SUCHANGLI /e/eoe_client/android-app (master)





因为我的本地仓库和远程仓库代码相同所以没有其他任何信息
4. 把远程下载下来的代码合并到本地仓库，远程的和本地的合并


1
2
3


$ git merge origin/master
Already up-to-date.
su@SUCHANGLI /e/eoe_client/android-app (master)

加patch:


今天要打包最新的三個 commit 的話

    git format-patch -3

此時 git 便會幫你產生3個類似下列的檔案

0001-First.patch

0002-Second.patch

0003-Third.patch



2.那如果要套用別人的patch 也相當簡單

    git am 0001-First.patch 

就將 patch apply 上去了

================================

刪除錯誤提交commit:

方法: 

    git reset --hard 

    git push origin HEAD --force

ubuntu build kernel

看這個：

http://it.livekn.com/2013/01/compile-kernel.html

安裝cmake與其相關套件東東

ubuntu 14.04: 

apt-get install cmake flex libpciaccess-dev bison libx11-dev libxext-dev libxml2-dev libvdpau-dev

apt-get install build-essential -y

apt-get install doxygen

ubuntu修改grub開機時間

here:
/etc/default/grub

after modified should be updated:

update-grub

xeyes X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:11.0

發現X11 connection有問題，原來是我變成"su"之後執行指令就產生以下訊息：
xeyes X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:11.0


解法：

An easier solution follow as:
1.- ssh user@host

2.- $ sudo su

3.- # xauth merge /home/user/.Xauthority

centos apache server python 網頁

在 /etc/httpd/conf/httpd.conf

寫 AddHandler cgi-script .cgi .py

service httpd restart

chmod 755 /var/www/cgi-bin/test.py

ＯＫ～

一些build new kernel的東東

http://people.cs.nctu.edu.tw/~chenwj/dokuwiki/doku.php?id=ubuntu

其中在ubuntu 12.04，若有改boot options，在/boot/grub/grub.cfg

改完要update-grub
