SearchWorldEnhance

Mod Synopsis

This is a lightweight mod run on client-side, which brings a “Search World” box to world selection screens(prior MC 1.13) and enhance the searching behaviour by using key-value pair arguments.

How to Use This Mod

This mod adds a “Search World” box to the world select screen(prior MC 1.13), and the searching behaviour is now like this:
worlddirname-=foo – Search for worlds whose directory names contain foo, case-sensitive
worldname/="^New World$" – Search for worlds whose names exactly are New World, case-insensitive
gamemode=S,commands=true – Search for worlds whose default game modes are Survival and commands are enabled

Format of Arguments

Each two key-value pairs are separated by ,(which means &&(and), and trailing , is allowed once). In contrast, a key-value pair is like this: <key_name><relationship_symbol><value>.
For regex keys, available relationship symbols are:

• = – left contains right, case-insensitive
• != – left does not contain right, case-insensitive
• -= – left contains right, case-sensitive
• !-= – left does not contain right, case-sensitive
• /= – left matches right, case-insensitive
• !/= – left does not match right, case-insensitive
• /-= – left matches right, case-sensitive
• !/-= – left does not match right, case-sensitive

Values are strings like this:

• foo – resolved as foo
• "Foo Bar" – resolved as Foo Bar
• "One says \"\\s are useful\"" – resolved as One says "\s are useful"

For long keys, available relationship symbols are:

• = and == – left equals right
• < – left is less than right
• <= – left is less than or equal to right
• > – left is greater than right
• >= – left is greater than or equal to right
• != – left does not equal right

Values are long integers like this:

• 0
• 1234567
• -98765432109999

For enum keys, available relationship symbols are:

• = – left is right
• != – left is not right

Values are all enums defined by the enum class and null.

For boolean keys, there is only one available relationship symbol =(means left is right).

Values are like this:

• true, t, yes, y, 1 – for true
• false, f, no, n, 0 – for false

If the format of arguments is valid, expected search result will be shown. Note that results of original search behaviour will be shown together, e.g. if there is a world named gamemode=C whose default gamemode is Survival, when you type gamemode=C in the box, this world will still be shown as a part of the result. If you want to avoid this, you can type worldname!="gamemode=C",gamemode=C in the box.

There is a class rege.rege.minecraftmod.searchworldenhance.util.SearchKeyRegistry in this mod, you should register yours using this class’s static methods. All valid keys are non-empty strings without -, , =, !, >, <, ,, /, ", \. An example is in the static block of rege.rege.minecraftmod.searchworldenhance.SearchWorldEnhanceMain‘s source code.
