Numbers can be written in scientific notation or hexadecimal too: 314.16e-2 0.31416E1 0xff 0x56 Other Lua types You don't need to declare a number as signed or unsigned. Again, for non-programmers, a single type of number may be more intuitive than knowing how computers store integers vs floating point numbers, and whether there's single or double precision, etc. Numbers (both integers and floats/decimals)īesides Strings, there are Numbers. Likewise with the Table module for tables and the Math module for numbers. More advanced string manipulation is made easier with the core String module. There's no heredoc syntax.Īll Lua escaped characters: '\a' (bell), '\b' (backspace), '\f' (form feed), '\n' (newline), '\r' (carriage return), '\t' (horizontal tab), '\v' (vertical tab), '\' (backslash), '\"' (quotation mark ), and '\'' (apostrophe ) Multi-line strings use matching pairs of, similar to triple-quoted strings in Python. Strings are either single-quoted or double-quoted like Python or JavaScript (unlike C where characters are single-quoted and strings are double-quoted). Members where keys were not explicitly defined are mapped to integer offsets too, starting from 1, and not including members with key names defined: Table members can be accessed with bracket notation as in a dict or JS object or with dot-notation like JS objects (not Python dicts).Į.g. Unquoted strings can be the keys of a table (like JavaScript), as can variables inside brackets (or quoted strings inside brackets). That is probably more intuitive to non-programmers though. When used as an array, indexing starts from 1 and not 0 like other programming languages. It's also similar to a PHP Array but not a C array so much. That complex type is called a 'table' and is like a JavaScript object, and similar to a Python dict. Lua has only one main object type besides strings/numbers. The reason for matching double brackets for multiple-line comments makes sense when you learn that multi-line strings also start with ]. (there shouldn't be backslashes before the brackets) CommentsĬomments are weird though, especially without syntax highlighting which many non-programmers won't have: - single line, You can prematurely break out of a loop, but there's no continue statement. Function declarations start with function and end in end. Semicolons can, however, be appended to lines, optionally. Semicolons aren't required to end lines as in C-based languages, or separate parts of a conditional/loop. They also use the end keyword to close blocks, which makes sense to normal people, moreso than matching curly braces or requiring whitespace to be the same (Python).
Some things will be a little more familiar to Shell Scripting programmers because of the keyword do after while and for loops and the then keyword after an if. Instead those logical operators are known by the keywords and, or, not. Control keywordsįirst, the syntax and keywords make Lua seem like programming intended not for programmers used to esoteric syntactic knowledge like matching curly braces and ^ to mean logical-bitwise-exclusive-or or double-pipe (||) to mean "or". You have a reason for wanting to learn Lua already so let's jump in. It was created to be embedded in other programs, to provide a scripting environment to glue and interact with the mother program (Example: Renoise, as well as many games and game engines). Lua was not designed to be run alone though, and you should have in mind some other program which uses Lua already when learning Lua. It is object-oriented, and supports functional programming, and supports multi-threaded programming. WAV format for extra compatibility in any DAWĪs a bonus, I have also included some xnri phrased breaks which are pre-programmed which instantly beat match to your project, and also included the whole Renoise song file that I have created whilst making this track, so you can load up, analyze, and learn from it.Īlso included is a total of 16 stems at 170bpm, for you to use in your productions or even just try a practice mix in your favorite DAW.Lua is a simple language to learn, but with plenty of power. I have repacked all of the samples that I have used the video in SAMPLES WAV FORMAT: ( bass sounds, beats 170bpm )
#Renoise tutorial full#
It also contains the full track stems ( in WAV format at 170BPM ) This pack contains a full sample set and stems used in my Renoise and I have also packed it universally to work with all other DAWs
#Renoise tutorial series#
This pack accomplishments my youtube music production series, I have taken all of the samples used from this series to make one cool drum and bass sample pack download. Description: Bizzy B Science Renoise Stem Pack
