From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have a file with content like this:
item({
     ["attr"] = {
        ["size"] = "62091";
        ["filename"] = "qBuUP9-OTfuzibt6PQX4-g.jpg";
        ["stamp"] = "2023-12-05T19:31:37Z";
        ["xmlns"] = "urn:xmpp:http:upload:0";
        ["content-type"] = "image/jpeg";
     };
     ["key"] = "Wa4AJWFldqRZjBozponbSLRZ";
     ["with"] = "email@address";
     ["when"] = 1701804697;
     ["name"] = "request";
});
I need to know what format this is, and if there exists a tool in linux already to parse this or if I need to write one myself?

Thanks!

Lua function "item" called with argument of type table

The function is the outer part with the parentheses, the table is the inner part with the curly braces. ["attr"] is a table inside the table.

For example, to access (table)>attr>size you would write: table["attr"]["size"] (assuming the table is named, that is, assigned to a variable called "table")

This is correct. You can also omit the parentheses on the function call in Lua if the only argument is a table or string literal.
