Harmony HPM 包管理器
HPM
OpenHarmony HPM 指的是 “Harmony Package Manager”
HPM Part
Module level HPM Part:用于实现模块或 Part 的复用。分发的内容可以是源码或二进制文件。通常,这样的 HPM Part 对应着一个代码仓库,是代码仓库的一个版本。
hugo
theme: next
- install hugo
- create a new site
hugo new site <sitename>
- add theme
Usage of next theme
- download theme file: git clone
https://github.com/xtfly/hugo-theme-next.git
next - copy next directory to themes directory in your hugo site
- move config.toml to the root directory in your hugo site, and modify it to the actual information for your site.
- create some markdown files in directory(content/post), like
https://github.com/xtfly/xtfly.github.io/tree/hugo/content
- start hugo server in root directory: hugo server
- open browser:
http://localhost:1313/
- download theme file: git clone
- start server
hugo server --bind 0.0.0.0 --baseURL http://10.0.0.7:1313

环境
ubuntu 18.04 x64
依赖工具
- jdk 1.8
- universal-ctags
- tomcat8
- opengrok
配置流程
jdk 安装
sudo apt install openjdk-8-jdk openjdk-8-jdk-headless openjdk-8-jre openjdk-8-jre-dcevm openjdk-8-jre-headless
通常android编译环境能够正常工作jdk环境已经ok.
$ java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1~18.04-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)
universal-ctags
ubuntu 自带包管理器安装的 ctags
是 exuberant-ctags
, 如果已经安装请先通过如下命令卸载
OpenHarmony 代码下载编译
代码下载
OpenHarmony源代码以 [[HPM]] 部分的形式提供,可以通过以下任意方式获取:
从Gitee代码库获取源码。您可以使用repo或git工具从代码仓库下载最新的代码。
repo
环境准备
下载repo工具
user110@server005:~/bin$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo

samba
安装
For ubuntu
# smbclient 用来测试 samba 服务
sudo apt install samba smbclient
For arch
sudo pacman -Sy samba smbclient
配置文件
/etc/samba/smb.conf
末尾追加如下内容:
注意这里的 [share]
windows 映射网络驱动器的时候路径为: \\<ubuntu ip>\share
[share]
path = /home/username/Public
public = yes
writable = yes
valid users = username //映射时的登陆名
create mask = 0644
force create mode = 0644
directory mask = 0755
force directory mode = 0755
available = yes
设置密码
sudo touch /etc/samba/smbpasswd
sudo smbpasswd -a username
# then insert password
重启 samba 服务
For ubuntu
