Introduction

localenv creates a local CHICKEN scheme installation. It creates an alternative repository without polluting the system-wide repository.

In other words, it provides some of the features of virtualenv command for CHICKEN.

Installation

Clone this repository and put the localenv script inside a directory included in your $PATH environment variable, e.g. a ~/bin folder.

Usage

Create a local CHICKEN installation with the following.(let's call it sicp)

$ localenv sicp

Activate the localenv with:

$ . sicp/bin/activate

Install a new egg in the localenv with:

$ chicken-install sicp

Check installed eggs in the localenv with:

$ chicken-status

Deactivate localenv with:

$ deactivate

Modify the .csirc file in your home folder as follows:

(define local-csirc (get-environment-variable "LOCAL_CSIRC"))

(cond-expand
  (localenv

    (when (file-exists? local-csirc)(load local-csirc)))

  (else

   ;; put usual .csirc stuff here
))

localenv specific config should be written to localenv_dir/.init file. For example, to load the sicp module at startup, include the following line inside sicp/.init file:

(use sicp)
