You chosen a command shell and spent months to stuffed it with shortcuts and colors. But when you move from local to remote host using ssh you lose it all. The mission of xxh is to bring your favorite shell wherever you go through the ssh.

No installations or root access on the host required.

If you add `+I` arguments with appropriate xxh packages you can make your config file complete and simplify the usage command to `xxh myhost`. ### Install xxh packages ``` xxh [+I xxh-package ...] [+L] [+RI xxh-package ...] [+R xxh-package ...] ``` Different ways to set the xxh package source: ``` xxh +I xxh-shell-example # install from https://github.com/xxh xxh +I https://github.com/xxh/xxh-shell-example # short url for github only, for other sources use examples below or add support xxh +I https://github.com/xxh/xxh-shell-example/tree/mybranch # short url for github only, for other sources use examples below or add support xxh +I xxh-shell-example+git+https://github.com/xxh/xxh-shell-example # install from any git repo xxh +I xxh-shell-example+git+https://github.com/xxh/xxh-shell-example/tree/mybranch # install from git branch xxh +I xxh-shell-example+path+/home/user/my-xxh-dev/xxh-shell-example # install from local path ``` ## The ideas behind xxh **Portable**. By default building occurs locally and then xxh uploads the result to host. No installations or root access on the host required. The security and careful about environment on the host are behind it. **Careful**. No blindfold copying config files from local to remote host. The privacy and repeatability reasons are behind it. Every xxh package, shell or plugin is the bridge that use only what required, no more. **Hermetic**. If you delete `~/.xxh` directory from the remote host then xxh has never been on the host. If files appears outside xxh home directory feel free to report about this cases. **Fork-ready**. Every repo could be forked, customized and used without waiting of package management system, xxh releases or any third party. **Do more**. The xxh packages are not only about shells. Any type of tool or code could be behind "shell entrypoint". If you want to play Super Mario on the remote host just put it as entrypoint. **Be open**. Currently supported five shells and the count could be grow by community. ## Examples of use cases ### Python everywhere with xonsh When you run `xxh myhost +s xonsh-appimage` you'll get portable python, pip and python-powered shell on the host without any system installations on the host. Add plugins: [autojump](https://github.com/xxh/xxh-plugin-xonsh-autojump) saves time, [pipeliner](https://github.com/xxh/xxh-plugin-xonsh-pipe-liner) manipulates lines and [bar](https://github.com/xxh/xxh-plugin-xonsh-theme-bar) looks nice. ### Put the cozy configs to xxh session For example there is [xxh-plugin-prerun-mc](https://github.com/xxh/xxh-plugin-prerun-mc) which creates [Midnight Commander](https://en.wikipedia.org/wiki/Midnight_Commander) (mc) config when you go to the host using xxh. You can fork it and create your cozy settings for mc once and forever. ### Oh My Zsh seamless SSH ([demo](https://asciinema.org/a/rCiT9hXQ5IdwqOwg6rifyFZzb)) ```shell script source xxh.zsh myhost +I xxh-plugin-zsh-ohmyzsh +if +q ``` This command brings your current Oh My Zsh session theme to the xxh session. If you need more complex settings just fork the [xxh-plugin-zsh-ohmyzsh](https://github.com/xxh/xxh-plugin-zsh-ohmyzsh) and hack it. ### Read host as a table with osquery ``` $ xxh myhost +s osquery osquery> SELECT * FROM users WHERE username='news'; +-----+-----+----------+-------------+-----------------+-------------------+ | uid | gid | username | description | directory | shell | +-----+-----+----------+-------------+-----------------+-------------------+ | 9 | 9 | news | news | /var/spool/news | /usr/sbin/nologin | +-----+-----+----------+-------------+-----------------+-------------------+ ``` ### All in one portable home The xxh is very agile. You can create your own `xxh-shell` (shell word means it has entrypoint) which has any portable tools that you could help you on the host. [Bash-zero](https://github.com/xxh/xxh-shell-bash-zero) xxh-shell is one of this platforms that could be forked and stuffed. ## [Questions and answers](https://github.com/xxh/xxh/wiki) If you have a question first of all review the [wiki](https://github.com/xxh/xxh/wiki) and if there is no answer [ask the question](https://github.com/xxh/xxh/issues/75). ## Development In the [xxh-dev](https://github.com/xxh/xxh-dev) repo there is full [docker](https://www.docker.com/)ised environment for development, testing and contribution. The process of testing and development is orchestrated by `xde` tool and as easy as possible. **We have teams.** If you're in team it does not oblige to do something. The main goal of teams is to create group of passionate people who could help or support in complex questions. Some people could be expert in one shell and newbie in another shell and mutual assistance is the key to xxh evolution.
