This project will contain samples of API usage for the [UnitedGold](https://dev.unitedgold.io) project.

|
||||
## [kmp_console](kmp_console): native and JVM console app
|
||||
|
||||
- [jvm_console](jvm_console) simple JVM console application
|
||||
simple JVM/Native console sample application.
|
||||
|
||||
### jvm variant
|
||||
|
||||
./gradlew kmp_console:runJvm
|
||||
|
||||
You can create distribution with
|
||||
|
||||
./gradlew kmp_console:installJvmDist
|
||||
|
||||
You will find it in the ./kmp_console/build/install/kmp_console-jvm: the whole file tree is needed. You can rain it from command line with
|
||||
|
||||
./kmp_console/build/install/kmp_console-jvm/bin/kmp_console
|
||||
|
||||
or, on windows,
|
||||
|
||||
./kmp_console/build/install/kmp_console-jvm/bin/kmp_console.bat
|
||||
|
||||
This distribution only needs JDK be installed, like OpenJDK 17+ or Amazon Coretto 17+. It still will be much larger, even zipped, than native variant below.
|
||||
|
||||
|
||||
### Linux x64 console
|
||||
|
||||
./gradlew kmp_console:runDebugExecutableLinuxX64
|
||||
|
||||
To create standalone binary executable for linux x64:
|
||||
|
||||
./gradlew kmp_console:linkReleaseExecutableLinuxX64
|
||||
|
||||
The file is created is ./kmp_console//build/bin/linuxX64/releaseExecutable/kmp_console.kexe - to run it
|
||||
|
||||
./kmp_console//build/bin/linuxX64/releaseExecutable/kmp_console.kexe
|
||||
|
||||
You can reduce its size as usually with KMP natives by stripping and upxing it:
|
||||
|
||||
strip ./kmp_console//build/bin/linuxX64/releaseExecutable/kmp_console.kexe
|
||||
upx ./kmp_console//build/bin/linuxX64/releaseExecutable/kmp_console.kexe
|
||||
|
||||
Now it should have sane size, considering how many features are packed inside (most of it not seen directly, as heavy encrypted parsec3 protocol).
|
||||
|
||||
This way you can create dependency-free server tools.

# Gradle start up script for POSIX generated by Gradle.
|
||||
#
|
||||
# Important for running:
|
||||
#
|
||||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||
# noncompliant, but you have some other compliant shell such as ksh or
|
||||
# bash, then to run this script, type that shell name before the whole
|
||||
# command line, like:
|
||||
#
|
||||
# ksh Gradle
|
||||
#
|
||||
# Busybox and similar reduced shells will NOT work, because this script
|
||||
# requires all of these POSIX shell features:
|
||||
# * functions;
|
||||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||
# * compound commands having a testable exit status, especially «case»;
|
||||
# * various built-in commands including «command», «set», and «ulimit».
|
||||
#
|
||||
# Important for patching:
|
||||
#
|
||||
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||
#
|
||||
# The "traditional" practice of packing multiple parameters into a
|
||||
# space-separated string is a well documented source of bugs and security
|
||||
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||
# options in "$@", and eventually passing that to Java.
|
||||
#
|
||||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||
# see the in-line comments for details.
|
||||
#
|
||||
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||
# Darwin, MinGW, and NonStop.
|
||||
#
|
||||
# (3) This script is generated from the Groovy template
|
||||
# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
|
||||
