CMaterialColors is a library that contains all MaterialColors you need in Jetpack Compose projects.

Usage

Get the library

You can choose one of these ways to get it.

• Simply copy the file which locates at lib/src/main/java/com/funny/cmaterialcolors/CMaterialColors.kt to your own project , and then modify the package name
• Add maven source maven { url "https://jitpack.io" } in your project's build.gradle and dependencies implementation 'com.github.FunnySaltyFish:CMaterialColors:1.0.21 in your module's build.gradle

If you wonder why the first version is 1.0.21,what I can tell you is that I've tried (more than) 20 times to upload it to jitpack.io!!!

Use it in kotlin code

import com.funnty.cmaterialcolors.MaterialColors

/*...*/

Surface(color = MaterialColors.Red200) {
    Text(text = "FunnySaltyFish", modifier = Modifier.padding(4.dp),color = MaterialColors.PurpleA700)
    /*Anything like this*/
}

That's it!

What's More

How I write the library?

Actually, all of the codes are generated by a python script as below:

import re
import os

"""
    generate kotlin colors
    @copyright : FunnySaltyFish [github](https://github.com/FunnySaltyFish)
    @date : 2021/06/14 22:28:48
"""

text = """
    <color name="Red50">#fde0dc</color>
    <color name="Red100">#f9bdbb</color>
    ...
"""


def generate_colors(xml:str):
    """ generate kotlin code by using android resources xml file
        @params xml source xml file 
    """
    pattern_color = re.compile(r"<color name=\"(.+)\">(.+)</color>")
    find_colors = re.findall(pattern=pattern_color,string=xml) #find all colors by re module
    result_code = ""
    for (name,color) in find_colors:
        name = name.replace("_","") #replace redundant symbol "_" 
        color = color.replace("#","0xff")
        color = color.upper() #change the color into a stander format 
        result_code += f"@Stable\nval {name} = Color({color})\n" #generate the kotlin code
    return result_code

if __name__ == "__main__":
    code = generate_colors(text)
    file_path = "./code/code.txt"
    if not os.path.exists(file_path): #create folder if that dose not exist
        os.makedirs(os.path.dirname(file_path))
    with open(file_path,"w",encoding="utf-8") as f:
        f.write(code)

To get the full code, check the file generate_code_by_xml.py

About the example

To check all supported colors , you can download the demo.apk. It uses reflection to show all the colors.
