String provides access to basic string functions. This module allows simple text manipulation and is dozens of times more efficient that its parser function counterparts. MediaWiki's native string functions have a upper limit defined by wgPFStringLengthLimit as 1000 characters - this module lacks any such limit and is much more performant --- Pads str to length len with char from rightstring.lpad = function(str, len, char) if char == nil then char = ' ' end return str .. string.rep(char, len - #str)end Report this snippet Tweet Hmm. That's strange. When I get a moment I'll check into that. Should be able to do that easily. 55 mSecs is a lifetime in any case, and if the command is actually processed it should operate.

Unfortunately, I can't find a nice way to add a zero in front of the seconds if it is less than 10 seconds without a separate if statement Tutorials Formatting values using string.format() Formatting a particular string is a common requirement in almost any app, whether it be limiting the number of decimal places in a long number, adding placeholder spaces, or padding a score with leading zeros. The string.format() function is almost infinitely powerful for this task No. Those are written in C of course, and strings in C have a zero terminator. So whatever is beyond the zero is not part of the string as far as they are concerned. On decoding, these extra padding characters will be discarded.

If you need to skip the padding of the output - perhaps, because the resulting String will never be decoded back - you can simply chose to encode without padding

crypto.encrypt()¶ Encrypts Lua strings. One way of stripping such padding is to use :match((.-)%z*$) on the decrypted string. Additional care needs to be taken if working on binary data, in which case the real length likely needs to be encoded with the data, and at which point :sub(1, n) can be used to strip the padding When indexing a string in Lua, the first character is at position 1 (not at 0, as in C). Indices are allowed to be negative and are interpreted as indexing backwards, from the end of the string. Thus, the last character is at position -1, and so on. The string library provides all its functions inside the table string 33 In Lua 5.2 or earlier, both tostring(10) and tostring(10.0) result as the string "10".The conversion of a float to a string now adds a .0 suffix to the result if it looks like an integer. (For instance, the float 2.0 will be printed as 2.0, not as 2.) You should always use an explicit format when you need a specific format for numbers.

Looking at your example code,  I realise my first reply might not have been so helpful. You seem to be intent on using gsub. And also confusing the charact "0" with the zero value, "\0". (The ASCII character 0 is actualy hex 30, or decimal 48 -- certainly not zero). pack.lua wraps and bundles a lua source tree into a single source file.

As a special case, the empty capture () captures the current string position (a number). For instance, if we apply the pattern "()aa()" on the string "flaaap", there will be two captures: 3 and 5. Why not use the facility to remove the menu immediately (see para starting "When you no longer need the menu entry ....").

Lua modules based on the Scribunto/Lua extension are stored in resource pages using the Module: namespace. Each module uses a table to hold functions and variables, and that containing table is returned at the end of the module code. Tables are associative arrays or collections of data with key / value pairs that may be used to hold, organize and access data That zero tells string.format() to prepend leading zeros. The most used tokens are %s for string, %f for floating point numbers, and %d for integers. There are others, and they can be looked up in the Lua manual. Upper and Lower Case To convert a string to upper case, use string.upper(str). To convert a string to lower case, use string.lower(str)

The object's padding is determined through a query-string, usually with 'callback' as the parameter and the function name as the value. What is the Lua Engine? Lua is a widely used lightweight, high-performance scripting language, used for all sorts of applications from games to web applications and image processing So, in order to concatenate these zero-terminated strings you need to find the position of the zero and use the length to that to extract the substring for concatenation. You only need to do this for the first string of course.

String.pack/unpack seems more elegant but I struggle to see how to map to that Looks for the first match of pattern (see Patterns) in the string s. If it finds a match, then find returns the indices of s where this occurrence starts and ends; otherwise, it returns nil. A third, optional numeric argument init specifies where to start the search; its default value is 1 and can be negative. A value of true as a fourth, optional argument plain turns off the pattern matching facilities, so the function does a plain "find substring" operation, with no characters in pattern being considered magic. Note that if plain is given, then init must be given as well.

Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext).It is used to transform a data into some un-readable form so that authenticated person only can read/access the data. It requires some secret information to transform the plain text to cipher text; it is usually referred as key Alignment works as follows: For each option, the format gets extra padding until the data starts at an offset that is a multiple of the minimum between the option size and the maximum alignment; this minimum must be a power of 2. Options "c" and "z" are not aligned; option "s" follows the alignment of its starting integer.

Added DES encryption of simple strings; add resty.uuid wrapper; added pure lua function PHP-like explode() to string.lua; save and load context for md5; add function for padding setting; add len parameter in update() of resty.md5; Improve #35 pull request, we can set padding; feature: support OpenSSL 1.1.0+ use origin input key by defaul I am assuming the console window and ipc.display automatically removes the padding prior to displaying - or something.. Am I at a 256 byte limit for manipulation? Really Stumped here. Writes the C string pointed by format to the standard output ().If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers. Parameters format C string that contains the text to be written to stdout. It can optionally contain embedded format specifiers. A character class is used to represent a set of characters. The following combinations are allowed in describing a character class: 6.2 String Manipulation. This library provides generic functions for string manipulation, such as finding and extracting substrings. When indexing a string, the first character has position 1. See Section 8.3 for some examples on string manipulation in Lua. strfind (str, substr, [init, [end]]) Receives two string arguments, and returns a number

The output string will be 4/3 times as large as the input string, plus some possible padding to make up the result to a multiple of 4 (the padding character is =). Also, if you request linebreaks there will be a further 2 byte for every 76 bytes output (that is, every 57 bytes of input). The default is to not have linebreaks The definitions of letter, space, and other character groups depend on the current locale. In particular, the class [a-z] may not be equivalent to %l. string1 = "Lua" print("\"String 1 is\"",string1) string2 = 'Tutorial' print("String 2 is",string2) string3 = [["Lua Tutorial"]] print("String 3 is",string3) When we run the above program, we will get the following output.

The most straightforward way to get some value, some string or number, that you created or modified in the Lua back to your skin is to simply use the return someValue function built-into Lua. When a Lua script measure is updated in the skin, it will always look for an Update() function in the script file This module offers basic facilities to convert Lua values to and from C structs. Its main functions are struct.pack, which packs multiple Lua values into a struct-like string; and struct.unpack, which unpacks multiple Lua values from a given struct-like string.. The first argument to both functions is a format string, which describes the layout of the structure DESCRIPTION. This module provides access to terminfo database entries, see man terminfo.. This database provides information about a terminal, in three separate sets of capabilities. Flag capabilities are boolean (more accurately, they are either true or nil); they indicate the presence of a particular ability, feature, or bug.Number capabilities give the size, count or other numeric detail of. Documentation Edit. Official Transformice documentation can be found here.. Unofficial documentation for the Module API - the system built into Transformice that allows minigames to run without a bot. Modules are programmed in Lua. This documentation is valid as of Module API version 0.19 Lua 1 - Provides the end user of keyboard / joystick activation of our configuration program. It also acts as a slave to #s 2 & 3.


Functions in a Lua script may be executed inline, by using a call to a single function() within the Lua script, with optional parameters. The Lua function will be executed, using the provided parameters, and the single number or string value returned by the function() in the Lua script will replace the [Section Variable] where it is used How to format a string longer than 99 characters in Lua Ask Question Asked 2 years ago Active 2 years ago Viewed 508 times .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 3 I am formatting strings to be printed to the console and trying to format for the terminal size. However, Lua appears to not allow any type of formatting longer than 99 characters. (source) In any case, if the pattern specifies no captures, then it behaves as if the whole pattern was inside a capture. Copyright © 2015–2018 Lua.org, PUC-Rio.

stringx.lua--- Python-style extended string library. -- -- see 3.6.1 of the Python reference. -- If you want to make these available as string methods, then say -- stringx.import() to bring them into the standard string table Any format string starts as if prefixed by "!1=", that is, with maximum alignment of 1 (no alignment) and native endianness.  Finally got it... A fresh day with fresh brain cells helped. Was writing to zero to the correct slot. I reckon lua cleaned itself up before the write could be made. Yes, of course. Gradually little errors in the document are coming to light. I've corrected it here so it will be okay on the next release.local str = tostring(n) if str:sub(-2) == ".0" then str = str:sub(1,-3) end share | improve this answer | follow | | | | answered Mar 16 '16 at 17:01 warspykingwarspyking 2,65822 gold badges1414 silver badges3333 bronze badges add a comment  |  Your Answer Thanks for contributing an answer to Stack Overflow!
