eisl: A C repository from ORYZAPAO

Easy-ISLisp(EISL) is an interpreter and compiler compatible with ISLisp standard.EISL was written by me(Kenichi Sasagawa)

Installation
On Linux  type "make" on terminal.

On Windows rename winmakefile -> makefile. and type "make" on terminal.
Require MINGW gcc

We confirmed the operation in the following environment.
Ubuntu 16.04 GCC 5.4
Raspbery Pi3 Raspbian GCC 6.3
openSUSE Leap 42.3 GCC 4.8.5
Debian GNU/Linux GCC 6.3
Windows10 MINGW GCC 5.3


Invoke
eisl (Windows)
./eisl (Linux)

Linux version, REPL is editable. If you not use editable REPL, invoke with -r option.

./eisl -r

Goal
I hope that Lisp will become more popular. I hope many people enjoy Lisp. EISL aims at easy handling.

Compiler
EISL has compiler. it generate GCC code and generate object code.

Invoke with -c option
./eisl -c compiler.lsp

or (load "compiler.lsp")

(compile-file "foo.lsp")

(load "foo.o")

example
./eisl -c compiler.lsp

Builtin editor
EISL(Linux version) has builtin editor.

Invoke editor
(edit file-name-string) example (edit "foo.lsp")

(edit nil) edit recent file again.

Command
CTR+O save file.
CTRL+X quit editor.
CTRL+K delete selection.
CTRL+U paste from clip board.
Editing
↑↓←→ move cursol
ESC A mark current row position. After this operation, cursol up or down reverse selected rows. ESC A again, unmark. Similer to nano editor
Enter key insert tab for Lisp automatic
Insert key switch insert/overwrite
Tab key insert tab for Lisp
BackSpace key delete backword char
Delete key delete forwaord char
Home key display top page
ESC |(SSH)
End key display end page
ESC /(SSH)
PageUp key PageUp
Ctrl+Y(SSH)
PageDown PageDown
Ctrl+V(SSH)

ESC TAB completion.

Setting
(set-editor 'indent 'auto) set auto indent mode.
(set-editor 'indent 'manual) set manual indet mode. To indent tab key.
(set-editor 'tab 'lisp) set tab for Lisp style.
(set-editor 'tab 2) set tab 2.
(set-editor 'tab 4) set tab 4.
(set-editor 'tab 8) set tab 8.

syntax highlighting.
n = 0-7
0=Black, 1=Red, 2 =Green, 4=Blue, 5=Maggenta, 6=Syan, 7=White.
(set-editor 'syntax-color n)
(set-editor 'builtin-color n)
(set-editor 'extended-color n)
(set-editor 'string-color n)
(set-editor 'comment-color n)


WiringPi
Version for Raspberry include library for wiringPi.

In order to use wiringPi, you need to compile wiringpi.lsp(in example folder) and invoke EISL with super user.

sudo ./eisl

and (load "wiringpi.o")

please see exsample code "led.lsp"

"wiringpi.lsp" is source code of wiringpi.o.
