Easy-ISLisp

Easy-ISLisp(Windows)

Easy-ISLisp(Linux Ubuntu)

Easy-ISLisp(for raspberry3 Linux Raspbian)



When Linux version, Please unpack tar file.

tar xvf eisl.tar
or
tar xvf raseisl.tar

To invoke EISL, enter command from terminal

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")

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 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.
