DerpScript
Minecraft Java mod. Downloads from the MC Java Mods app on Android.
⬇ Download on SpigotSmall plugin that I wrote just because I wanted small break from updating my AutoIn plugin.
Main "feature" of this plugin, is only 100 lines of code.
What this plugins does?
This is just very small scripting plugin.
PS: Professional logo!
Yeach, that all
just one more useless plugin!
Main "feature" of this plugin, is only 100 lines of code.
What this plugins does?
This is just very small scripting plugin.
PS: Professional logo!
Implemented features:
- Whole plugin is based on simple one-word tokens, and it's uses reverse polish notation All the way... so yeach, it's hard to write something, like you should write "5 5 + 2 *" instead of "(5+ 5) *2"
Most of actions will "consume" item from stack, exceptions are: print and DUP
All operations are executed on top variable from the stack (a.k.a. current) - +, -, /, *
Simple Math symbols, plugin use double and long for all operations. - simpleWorld
Every word that isn't reserved keyword it's saved to memory as String.
You can escape reserved keyword by \\, like \\+ \\print etc..
To use empty string or space see LOAD keyword. - numbers
Every typed number will be also added to stack, it support long and double numbers. - booleans
Use TRUE or FALSE to add value to stack, you can use:
+ on booleans works like OR gate (just A + B)
- A must be TRUE and B must be FALSE to return TRUE. (just A - B)
* on booleans works like AND gate (just A * B)
/ is exception, and it works like XOR gate. (A ^ B in java) - print
Prints last element from stack to console. - DUP
Add copy of current (top of the stack) variable to stack. - DEL
Remove variable from top of the stack. - <name> SAVE
Save variable to hashMap in plugin, use "name SAVE", and current (or current before "name" was added) variable from top of the stack will be saved to memory. - <name> LOAD
Load variable from memory, "name LOAD" and variable is added to top of the stack.
There are two variables "build-in" to memory, "space" and "empty", so this is just string with one space and empty string. - <size> <class> NEW_ARRAY
Create new array with selected size. (it's filled from stack)
If you wrtie:
"one two three four five 4 java.lang.String.class NEW_ARRAY" you will get String[] {five, four, three, two} array.
PS: yes, there is no method to set/get object from memory, sorry, 100 lines isn't enough, (you can try use INVOKE and java.lang.reflect.Array for that) - <object> <paramTypes... (separated by space)> <className#methodName> <num of params> INVOKE
invoke selected method from java.
If method is static, just use space in place of object, so it will be double space between objects from stack and paramTypes.
"2 3 double.class double.class java.lang.Math#pow 2 invoke" (see, there are two spaces after "3", this mean that there is NULL value) This method will invoke Math.pow(3,2), results from methods with void return type will be not added to stack.
Not implemented features:
(for 99.99% I will not implement them in main branch [see github], 100 lines is max, maybe if someone find way to implement one of them without adding new lines)
(for 99.99% I will not implement them in main branch [see github], 100 lines is max, maybe if someone find way to implement one of them without adding new lines)
- Logic instructions
Something that will run instruction only if boolean from top of the stack is TRUE - Negation
Some easy way to change TRUE to FALSE and FALSE to TRUE. - Array get/set
method for get and set object to/from array. - Goto
Some way to jump to other line of code. - Bukkit Listeners and Tasks
Some easy way to create bukkit listeners and tasks
How to install and use:
Place .jar file to your plugins folder, create "DerpScript" folder, and add scripts here, each script MUST have ".drp" extension, like "src.drp"
That all.
