gore 0.4.0 is released!

A new version 0.4.0 of gore, a Go language REPL, is released today 🎉.

motemen/gore

Recently I’ve become the new maintainer of gore after some conversations with the original author motemen. The first work was to merge some pull requests. And then I fixed some small bugs, added Makefile, refined CI configs. I also added some new features.

To upgrade or install gore, try go get -u github.com/motemen/gore/cmd/gore.

Bug fixes

• Fix Evaluated but not usederror for some cases (evaluating len(fmt.Sprint(1)) twice emits no error)
• Report token errors (foo # bar reports invalid token: "#")

New features

• Support function declarations
• Add :type command to see the type of an expression (like ghci)
• Add :clear command to clear the code in the current session
• Command name abbreviations (:i for :import, :t for :type, :q for :quit, etc.)

Improvements

• Support Go 1.12 (be sure to upgrade gocode and godoc, too)
• Add Makefile
• Move main package to cmd/gore/
• Print header on startup to stdout (like python)
• Improve temporary directory (add gore- prefix, remove on exit)
• Filter out temporary filenames from compile errors
• and more small improvements

Here’s a screenshot of new version of gore.

If you notice some problems, feel free to submit an issue report to https://github.com/motemen/gore/issues. I’m going to improve gore more and more! Thank you!
