How to compile Prolog with GProlog and SWI-Prolog (Linux)

GProlog

Application must contain such piece of code

:-initialization(Goal).

 Then executable file can be built with

gplc --min-size PrologFile.pl

To decrease size of resulted file just use upx utlity

upx --all-methods exeFile

SWI-Prolog

Add some main goal into Prolog application

main :- Goal, Goal, Goal.

Compile with string

swipl -O --foreign=save --toplevel=halt --goal=main --stand_alone=true -o exeFile -c PrologFile.pl

Check usage of system libraries with

ldd exeFile

It will show something like

linux-vdso.so.1 =>  (0x00007ffcdc3f8000)
libswipl.so.7.2 => /usr/lib/libswipl.so.7.2 (0x00007febe1ec8000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007febe1cab000)

libswipl.so.X.X is used by the executable file and must be bundled together with compiled file

added one more example for JBBP

Added one more example for JBBP to show how to add a custom type into parser, as example I have written a parser for three byte non-signed integer value with "int24" as name of the type . The Example formed as a JUnit test and published in the GitHub.

Java Comment Preprocessor 6.1.0

The New 6.1.0 version of Java Comment Preprocessor is out and published in Maven central. From main features of the new version I can distinguish
added option to enable whitespace between comment chars and directive, it 1) makes possible to write in such style
// #local VAR="hello"
also spaces will be allowed in //$$, //$ and /*-*/ directives
2) fixed bug in work with absolute path files
3) added function binfile(STR,STR) which converts binary files into text representation
Example:
byte[] TEXT=byte[]{/*$binfile("./file.bin","byte[]")$*/};
will be converted into
byte[] TEXT=byte[]{(byte)0x89,(byte)0x50,(byte)0x4E,(byte)0x47,(byte)0xD,(byte)0xA,(byte)0x1A,(byte)0xA};
it supports "base64","base64s" (it splits text to 80 char lines), "byte[]" and "byte[]s"

"Hello World!" in GoLang with Maven

if you have installed maven on your machine and would like to try GoLang then now it is possible in just two terminal lines:

 

$ mvn archetype:generate -B -DarchetypeGroupId=com.igormaznitsa -DarchetypeArtifactId=mvn-golang-hello -DarchetypeVersion=2.0.0 -DgroupId=com.go.test -DartifactId=gohello -Dversion=1.0-SNAPSHOT

$ mvn -f ./gohello/pom.xml package

 

The First line creates a simple GoLang project from a maven archetype, the project is based on usage of the mvn-golang-wrapper, and the second one build and run the project.

GoLang with Maven

I very like the Maven build tool and decided to make some plugin to wrap main GoLang commands and provide possibility to build GoLang applications directly with Maven. For that I have started OSS project https://github.com/raydac/mvnGoLang
It wraps commands:

• clean
• get
• build
• install
• test

also it can automatically download needed GoLang SDK and cache it.
