Rusty Bash (a.k.a. sushi 🍣 shell)

IMPORTANT: the main branch is switched to the shell develped for articles on SoftwareDesign. （今までのメインブランチは、連載のものに比べて散らかりすぎなので、連載のものをmainに切り替えました。）

• old main branch

What's this?

A clone of Bash, which is developed as a hobby of our group and for monthly articles on SoftwareDesign magazine published by Gijutsu-Hyohron Co., Ltd.

Quick Start

$ git clone https://github.com/shellgei/rusty_bash.git
$ cd rusty_bash
$ cargo build
...
🍣 echo hello
hello
🍣 exit

For Contributors

Since the main branch must synchronize the articles, further developments are reflected in the following branches. We prepared dev-* branches for adding your codes with pull requests.

• dev-builtins: for builtin commands
• dev-signal: for development on signal
• dev-compounds: for development on compoundss
• dev-args: for development on arguments
• dev-test: for development of a nice test system and test cases (we need more sophisticated test)
• dev-others: for development of other features

These dev-* branches will be merged to the main branch depending on the situation of the articles. You can also propose some dev-foobar branches.
