ipairs() type of tables with numerical indices. This is the standard Lua way of getting the size of index tables i.e. Parametersįor index based tables you can get the size with the # operator: See for more info table.size table.size (t) Returns the size of a key-value table (this function has to iterate through all of the table to count all elements). The sort algorithm is not stable that is, elements considered equal by the given order may have their relative positions changed by the sort. If comp is not given, then the standard Lua operator < is used instead. The reply contains the incoming messages (as a JSON array). Mudlet can do HTTP requests in the background, so we send a long poll PUSH request to the Python server. Details: slop in the natural therapeutic mud pool ,cake the mud (let mud. It establishes a bidirectional link between Mudlet/Lua and Python and exchanges structured messages between the two. If comp is given, then it must be a function that receives two table elements, and returns true when the first is less than the second (so that not comp(a,a) will be true after the sort). Details: viewing orchids,stroll among an array of gardens ,across lily ponds. There is another form of variables in Lua called tables which can be used for lists, arrays or dictionaries. "/a", mytable ) table.sort table.sort(Table ) Sorts table elements in a given order, in-place, from Table to Table, where n is the length of the table. Saves the table mytable to the lua file mytable in your Mudlet Home Directory table. table.keys table.keys(table) return a table that is the collection of the keys in use by the table passed in Parameters index_of ( words, "greetings" )) end table.is_empty table.is_empty(table) Check if a table is devoid of any values. contains ( words, "greetings" ) then table.remove ( words, table. The function to use for determining what order to iterate the items in the table. Spairs spairs(tbl, sortFunction) Returns an iterator similar to pairs(tbl) but sorts the keys before iterating through them.
Through them you can add to tables, remove values, check if a value is present in the table, check the size of a table, and more. But first we need to consider space-based computing platforms and, in general terms, how they’ve influenced the operating system of choice.These functions are used to manipulate tables. We’re going to be looking at where Linux is being used in space exploration. So, we’ll also investigate what’s held Linux back in space and, to a significant degree, continues to do so today, and what the prospects are for it to boldly go where no operating system has gone before. with scripting in Lua - Mudlet/.clang-tidy at development Mudlet/Mudlet. The migration of Linux into space is a recent phenomenon, though, and it’s still far from universal. And that takes us from NASA’s supercomputers here on Earth, through to laptops in orbit on the International Space Station (ISS) and flight control computers on SpaceX’s launch vehicles and spacecraft, to a single board computer empowering a helicopter flying on Mars.Īs well as looking at where and how Linux is used in astronautics, we’ll also delve into why it’s used. But all that’s changing, so we’ll be looking at how Linux is becoming an important facilitator in space exploration.
Mudlet array full#
Joking aside, the truth is that the heavens aren’t full of Linux-toting computers.

Why do astronauts use Linux? Because you can’t open Windows in space.
