android-xml-formatter

Preface

This is a fork of ByteHamster's android-xml-formatter which aims to add functionality for printing to stdout. This will enable editors like Neovim to have formatting capabilities for android xml files using conform.nvim.

I've provided an example wrapper script for making it work with conform.nvim in scripts/. Here is an example config for conform too:

local conform = require'conform'

local home = os.getenv"HOME"

conform.setup({
    formatters = {
        android_xml_formatter = {
            inherit = false,
            command = home .. "/libs/JavaTools/android_xml_formatter",
            args = { "--stdout", "$FILENAME" },
            stdin = true
        }
    },
    formatters_by_ft = {
        xml = {"android_xml_formatter"}
    }
})

vim.keymap.set("n", "<leader>lf", function()
    conform.format({})
end)

Formats xml files according to Android Studio's default formatting rules. By default, also re-orders the attributes to specify the android:id, android:layout_width and android:layout_height first. This can be turned off with a command line option.

To view available command line options, execute java -jar android-xml-formatter.jar --help.

Can be used as a style check on a CI server by executing and then printing the diff.
