janet-good-repl

janet-good-repl is an improved REPL for the Janet programming language. It's based on Janet's builtin REPL (version 1.34.0) and adds these features:

• Multi-line input: Enter multiple lines that belong together (usually an s-expression) as a single history entry. This helps a lot when you want to repeat this expression (or a modified version of it) afterwards using the history. Use Alt-Enter to continue a multi-line entry.
• Bracketed paste: Paste a code block (p.e. from an editor) as a single multi-line input.
• Persistent history: The history is persistent between sessions.

Build and install

First, install Janet.

Then, install janet-good-repl:

git clone https://github.com/MaxGyver83/janet-good-repl.git
cd janet-good-repl
./build.sh
sudo ./install.sh

janet-good-repl consists of a single C file. When you build it, it gets linked against the installed Janet version.

Usage

Start janet-good-repl instead of janet. Both REPLs share the same command line arguments.

Windows and macOS

janet-good-repl was tested only on Linux. Maybe it works on macOS out of the box. If not, tell me or create a pull request. I think it won't work on Windows because it uses this path for the history file:

$HOME/.local/share/janet-good-repl/history

If you use Windows, please tell me what would be a good place for the history file.
