Vicr stands for "Vim-like Interactive CRystal" and represents a tiny command line application that designed to quickly execute Crystal code with fast feedback and options to proceed:
$ brew tap veelenga/tap $ brew install vicr
$ git clone https://github.com/veelenga/vicr $ cd vicr $ make $ sudo make install
Open terminal, run
vicr, write your Crystal program, save and exit.
Vicr is able to load file content for you to start playing with Crystal code straight away. For example:
# loads local file $ vicr src/vicr/cli.cr # loads Github file $ vicr https://github.com/manastech/crystal/blob/master/samples/2048.cr # loads Github gist $ vicr https://gist.github.com/veelenga/a5b861ccd32ff559b7d2#file-benchmark_test-cr # loads CarcIn file $ vicr https://carc.in/#/r/rlj # loads play.crystal-lang.org file $ vicr https://play.crystal-lang.org/#/r/rlj # loads raw file $ vicr http://example.com/program.cr
Use help (
-h flag) for more information.
It is possible to configure Vicr start-up settings using
~/.vicr/init.yaml configuration file.
You can customize settings and use your favorite editor and even change compiler params:
# ~/.vicr/init.yaml --- run_file: ~/.vicr/run.cr editor: executable: nvim args: - "--cmd" - "set paste" compiler: executable: crystal args_before: - "run" - "--no-debug"
