manjaro with python development environment configuration

1.manjaro arrangement

1.1. Startup Items

sudo update-grub

1.2 Source change:

sudo pacman-mirrors -i -c China -m rank 
sudo pacman -Syy

Note: Pacman commonly used commands

Pacman is the Arch Linux package manager. It combines a simple binary package format and easy to use build system combines. Whether the package is from the official Arch library or user-created, Pacman can get easy management.

Update System

In Archlinux using a command to update the entire system:
pacman -Syu
If you have used pacman -Sythe local package database with a remote warehouse synchronization can be performed only:pacman -Su

Installation package

➔ pacman -S package name: for example, the implementation of pacman -S firefox will install Firefox. You can also install multiple packages,
just to name a space separated package.
➔ pacman -Sy package name: The difference is that with the above command, the command will perform the installation package and then synchronize database.
➔ pacman -Sv package name: After the installation information display some operations.
➔ pacman -U: local installation package, which extension pkg.tar.gz.
Pacman -U ➔ http://www.example.com/repo/example.pkg.tar.xz install a remote packet (source arranged not inside pacman)

Delete Package

➔ pacman -R package name: This command will only delete the package to retain all of its dependencies installed
➔ pacman -Rs Package name: the removal of the package at the same time, remove all of its dependencies not be used by other installed packages
➔ pacman -Rsc package name: the removal of the package at the same time, remove all depend on this package of programs
➔ pacman -Rd package name: Do not check dependencies when deleting packages.

Search package

➔ pacman -Ss Keyword: Search contains keywords in the warehouse.
➔ pacman -Qs Keyword: Search installed packages.
➔ pacman -Qi package name: View detailed information on packages.
➔ pacman -Ql Package name: lists the files in the package.

Other Uses

➔ pacman -Sw package name: Only download packages, do not install.
➔ pacman -Sc: Cleaning up the package file is not installed, the package file is located in / var / cache / pacman / pkg / directory.
➔ pacman -Scc: cleaning up all the cache files.

1.3.Vim installation

sudo pacman -S vim

1.4. Adding archlinuxCN source

With vim editor /etc/pacman.conf -> command: sudo vim /etc/pacman.conf

In the bottom of the file add the following lines:

[archlinuxcn]
SigLevel = Optional TrustedOnly
Server = https://mirrors.ustc.edu.cn/archlinuxcn/$arch

Flush the cache key chains and introducing
the modified well above two portions, the terminal performs the following instructions:

sudo pacman -Syy && sudo pacman -S archlinuxcn-keyring

Then, upgrade the system

sudo pacman -Syyu

1.5 Installation Tools:

sudo pacman -S yaourt

1.6. Chinese fonts

Conventional Linux systems are the lack of Chinese fonts need to be installed

sudo pacman -S ttf-roboto noto-fonts ttf-dejavu
# 文泉驿
sudo pacman -S wqy-bitmapfont wqy-microhei wqy-microhei-lite wqy-zenhei
# 思源字体
sudo pacman -S adobe-source-code-pro-fonts 
sudo pacman -S adobe-source-sans-pro-fonts
sudo pacman -S adobe-source-serif-pro-fonts
sudo pacman -S adobe-source-han-sans-cn-fonts   
sudo pacman -S adobe-source-han-serif-cn-fonts  

1.7. Chinese input method

I like Sogou input method

sudo pacman -S fcitx-sogoupinyin
sudo pacman -S fcitx-im         # 全部安装
sudo pacman -S fcitx-configtool # 图形化配置工具

Edit the ~/.xprofilefile, add the following at the end of the file

export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS="@im=fcitx"

After logging off, you can see slightly fcitx icon in the lower right (or upper-left corner).

1.8 Application software installation

anaconda activation

In ~/.bashrcadding:

sudo vim ~/.bashrc

Activation pathway:

export PATH="/opt/anaconda/bin:$PATH"

Activate the default environment:

source /opt/anaconda/bin/activate base

Configuration Mirror:

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

1.8.6.ClamAV

Update the virus database

sudo freshclam

Error: Can't create temporary directory

If the following error occurs, use the expression with the UID and GID numbers ::

ERROR: Can't create temporary directory /var/lib/clamav/tmp

Hint: The database directory must be writable for UID 1000 or GID 1001
ERROR: Initialization error!

Correct permissions:

chown UID:GID /var/lib/clamav & chmod 755 /var/lib/clamav

eg: sudo chown 1000:1001 /var/lib/clamav & sudo chmod 755 /var/lib/clamav

Daemon installed

---

Systemctl should start the service named clamd.service

By sudo or as root:

sudo systemctl enable clamd.service
sudo systemctl start clamd.service

2.Vscode installation configuration python development environment

sudo pacman -S visual-studio-code-bin 

Vscode is an open source cross-platform editor. By default, the language used is English vscode (us), how to modify the language into Chinese?

1) Open the vscode tools;

2) Use the shortcut key combination [Ctrl + Shift + p], enter "configure display language" in the search box, click OK;

3）选择 Install additional languages，安装Chinese (Simplified) Language Pack for Visual Studio Code ;

4) Restart vscode tools;

5) Plug

The following diagram, open the software after installation, click on the icon in the bottom left of the search Python, the first selection list and click install a plug-in installation program.

6) plug-in installation Anaconda Extension Pack

7) plug-in name: Guides;

插件功能： 这个插件的作用是增加 .py 中的指示线，用这个插件能让代码的层次结构更加清晰。

8）插件名称：Bracket Pair Colorizer ；

插件功能： 这个插件的作用是给代码中的括号增加颜色，同一对括号是相同的颜色，尤其是在括号中还包着括号的时候，看起来更加的清晰。

9）文件头添加

• 自定义代码片段

1. 文件>首选项>用户代码片段
2. 搜索python
3. 添加代码

"HEADER":{
        "prefix": "header",
        "body": [
            "# -*- encoding: utf-8 -*-",
            "",
            "# @File    : $TM_FILENAME",
            "# @Time    : $CURRENT_YEAR/$CURRENT_MONTH/$CURRENT_DATE $CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND",
            "# @Author  : Wen Jungang ",
            "# @Version : 1.0",
            "# @Contact : [email protected]",
            "",
            "",
            ""
        ],
    }

• 添加文件头

1. 新建文件
2. 输入header
3. 选择header

10）打开工作目录

如下图，点击左边的 文件图标，再点击“打开文件夹”按钮，选择一个文件夹作为工作目录，之后新建的文件都会存放在这个目录下。
添加完后如下图，我的文件名为python，添加后所有字母都变为大写。

11）新建hello.py

如下图，点击左边文件的图标，鼠标移到工程的目录名，我的是VSCODEPROJECT，会出来一个有个+号的文件，点击，然后输入hello.py就会会生成.py文件，如何print("hello"),点击F5，在下面的调试窗口会出来一个hello,没有报错就说明已经配置成功了，接下来就可以进行Python的开发了。

12）代码格式化工具yapf

在VSCode中按下快捷键Alt+Shift+F即可自动格式化代码操作起来特别简单。
