Npt documentation.

Reference: ANSI Common Lisp npt
Next: 2. Compilation

1.1 How to install

Installation is done by compiling the source code with a C compiler. There are three ways to compile the source code: by script, by autoconf, and by hand. Another page shows how to compile manually. If the method on this page doesn’t work, please see that page, 2. Compilation.

First, download the source from github.

$ git clone https://github.com/nptcl/npt.git
$ cd npt

1.2 Compilation by Script

Compilation scripts for FreeBSD and Linux are available.
To compile on FreeBSD, execute the following steps

$ ./freebsd_release.sh

To compile on Linux, install gcc and gmake beforehand.
Execute the following steps

$ ./linux_release.sh

In both cases, the executable file npt is created.

1.3 Compilation by Batch File

Compilation batch file for Windows are available. It has been tested to work with Visual Studio 2017.
In order to compile, the following commands must be available.

CL.EXE
LINK.EXE
NMAKE.EXE

Execute the following steps

> windows_release.bat

The executable file npt is created. In some cases it may not work.
If this fails, check 2. Compilation and compile manually.

1.4 Compilation by autoconf

To compile with autoconf, run bootstrap.sh to generate file configure.

$ ./bootstrap.sh

After the file is generated, run configure.

$ ./configure

If you want to set the installation location, specify --prefix.

$ ./configure --prefix=/usr/local

Run make to compile.

$ make
$ make install

An executable file named npt is created when make is executed.
Execute make install and the executable file npt is copied to --prefix.

1.5 Installing the Executable File

If you have scripted compilation, copy the executable file npt to the location of your choice and the installation is complete. For example

$ ./freebsd_release.sh
...
$ cp -i npt /usr/local/bin/.

In the case of configure, make install copies npt to the location specified by --prefix.

The installation copies only one file, the executable npt.
If you want to uninstall, just delete the npt file.

1.6 `npt` example

When npt is launched, the prompt changes to *.

$ npt
*

Enter a Lisp expression and you will get the answer.

* (+ 10 20 30)
60
*

To exit, press Ctrl+D or execute (exit).

* (exit)
$

To load a file, specify --load or --script as an argument.

$ cat > aaa.lisp
(format t "Hello~%")
^D
$ npt --script aaa.lisp
Hello
$ npt --load aaa.lisp
Hello
* (quit)
$

See --help for details.
