For an +% introduction on this package (among others), please refer to the document +% \texttt{luatex-reference.pdf}. +% \end{abstract} +% +% \section{Overview} +% +% Lua is a very minimal language, and it does not have a lot of built-in +% functions. Some functions will certainly be needed by a lot of packages. +% Instead of making each of them implement these functions, the aim of this +% package is to provide a standard set of functions. All functions are taken +% from Con\TeX t libraries. +% +% There are some differences with the Con\TeX t funtions though, especially on +% names: for example the \texttt{file.*} funtions are renamed in +% \texttt{fpath.*}. It seems more logical as they deal with file paths, not +% files. Also the \texttt{file.is\_readable} and \texttt{file.is\_writable} +% are renamed \texttt{lfs.is\_readable} and \texttt{lfs.is\_writable}. +% +% If you use a function you think is missing in this file, please tell the +% maintainer. +% +% \texttt{Warning:} Even if the names will certainly remain the same, some +% implementations may differ, and some functions might appear or dissapear. As +% Lua\TeX\ is not stable, this file is not neither. +% +% All functions are described in this document, but the one of the functions +% you'll use most will certainly be \texttt{table.serialize} (also named +% \texttt{table.tostring}) that takes a table and returns an intented string +% describing the table. It describes the table so that Lua\TeX\ can read it +% again as a table. You can do a lot of things with this functions, like +% printing a table for debugging, or saving a table into a file. Functions are +% also converted into bytecode to be saved. +% +% \section{\texttt{lualibs.lua}} +% +% \iffalse +%<*lua> +% \fi +% +% \begin{macrocode} +do + local lualibs_module = { + name = "lualibs", + version = 0.93, + date = "2010/05/10", + description = "Lua additional functions.", + author = "Hans Hagen, PRAGMA-ADE, Hasselt NL & Elie Roux", + copyright = "PRAGMA ADE / ConTeXt Development Team", + license = "See ConTeXt's mreadme.pdf for the license", + } + if luatexbase then + luatexbase.provides_module(lualibs_module) + end +end +% \end{macrocode} +% Initialize \textsf{Kpathsea} library, so that |require()| will use it to +% locate modules. +% \begin{macrocode} + +kpse.set_program_name("luatex") + +% \end{macrocode} +% We could load the modules with |require|, but this works only from version +% 0.44, and doesn't work in Debian, so we simply use |dofile|. +% \begin{macrocode} + +local function load_lualibs_module(filename) + local path = kpse.find_file(filename) + if not path then + texio.write_nl(string.format("lualibs: error: cannot find file %s", filename)) + return + end + texio.write_nl('log', string.format("lualibs: loading file %s", path)) + --if (tex and tex.luatexversion and tex.luatexversion > 44) + -- or (status and status.luatex_version and status.luatex_version > 44) then + -- require(filename) + --else + dofile(path) + --end +end + +load_lualibs_module("lualibs-string.lua") +load_lualibs_module("lualibs-lpeg.lua") +load_lualibs_module("lualibs-boolean.lua") +load_lualibs_module("lualibs-number.lua") +load_lualibs_module("lualibs-math.lua") +load_lualibs_module("lualibs-table.lua") +load_lualibs_module("lualibs-aux.lua") +load_lualibs_module("lualibs-io.lua") +load_lualibs_module("lualibs-os.lua") +load_lualibs_module("lualibs-file.lua") +load_lualibs_module("lualibs-md5.lua") +load_lualibs_module("lualibs-dir.lua") +load_lualibs_module("lualibs-unicode.lua") +load_lualibs_module("lualibs-utils.lua") +load_lualibs_module("lualibs-dimen.lua") +load_lualibs_module("lualibs-url.lua") +load_lualibs_module("lualibs-set.lua") +load_lualibs_module("lualibs-dimen.lua") + +% \end{macrocode} +% Aliases for backward compatibility. +% \begin{macrocode} + +fpath = file +fpath.split = file.split_path +lfs.is_readable = file.is_readable +lfs.is_writable = file.is_writable + +% \end{macrocode} +% Functions no longer provided by Con\TeX t module. +% +% \begin{macro}{string:stripspaces} +% +% A function to strip the spaces at the beginning and at the end of a +% string. +% +% \begin{macrocode} + +function string:stripspaces() + return (self:gsub("^%s*(.-)%s*$", "%1")) +end + +% \end{macrocode} +% +% \end{macro} +% \begin{macro}{lpeg.space and lpeg.newline} +% +% Two small helpers for \texttt{lpeg}, that will certainly be widely used: +% spaces and newlines. +% +% \begin{macrocode} + +lpeg.space = lpeg.S(" \t\f\v") +lpeg.newline = lpeg.P("\r\n") + lpeg.P("\r") +lpeg.P("\n") + +% \end{macrocode} +% +% \end{macro} +% \begin{macro}{table.contains value} +% +% A function returning true if the value \texttt{val} is in the table +% \texttt{t}. +% +% \begin{macrocode} + +function table.contains_value(t, val) + if t then + for k, v in pairs(t) do + if v==val then + return true + end + end + end + return false +end + +% \end{macrocode} +% +% \end{macro} +% \begin{macro}{table.contains key} +% +% A function returning true if the key \texttt{key} is in the table +% \texttt{t} +% +% \begin{macrocode} + +function table.contains_key(t, key) + if t then + for k, v in pairs(t) do + if k==key then + return true + end + end + end + return false +end + +% \end{macrocode} +% +% \end{macro} +% \begin{macro}{table.value position} +% +% A function returning the position of a value in a table.
