README

        
[![CircleCI](https://circleci.com/gh/wryun/es-shell.svg?style=svg)](https://circleci.com/gh/wryun/es-shell)

Es is an extensible shell. The language was derived from the Plan 9

shell, rc, and was influenced by functional programming languages,

such as Scheme, and the Tcl embeddable programming language. This

implementation is derived from Byron Rakitzis's public domain

implementation of rc.

See the INSTALL file for installation instructions. Once it's running

have a look at the manual page and the docs and examples directories,

in particular Haahr & Rakitzis's paper: ``Es: a shell with higher-order

functions.'' The paper corresponds to a slightly older version of the

shell; see the file ERRATA for changes which affect parts of the paper.

The file initial.es, which is used to build the initial memory state of

the es interpreter, can be read to better understand how pieces of the

shell interact.

The official ftp site (associated with the original authors) is at:

    ftp://ftp.sys.utoronto.ca/pub/es

but all of the relevant information is mirrored in the repository and/or

the website:

    http://www.github.com/wryun/es-shell

    http://wryun.github.io/es-shell

including the change history and the old mailing list archives.

An old version of Paul's .esrc (es startup) file is provided as an

example as esrc.haahr; correctness is not guaranteed. A simple

debugger for es scripts, esdebug, is also included; this is very

untested and should be considered little more than a sketch of a few

ideas.
