+# URL Shortener
+
+Just a small file-based url shortener.
+
+Works with:
+* NGINX
+* LUA
+* Flask
+
+
+Since this is prepared to be a `deb` Package, `rsync src/ / -av` and @see `debscripts/*`
+
+
+It requires `NGINX 1.24` and the needed artifacts for a correct run on Ubuntu 24.04 are in the repo (ok, a bit unusual)

+-- it hooks into the parser and lists all functions of a chunk as they
+-- are parsed.

+--   luajit -jbc=- foo.lua
+--   luajit -jbc=foo.list foo.lua
+--
+-- Default output is to stderr. To redirect the output to a file, pass a
+-- filename as an argument (use '-' for stdout) or set the environment
+-- variable LUAJIT_LISTFILE. The file is overwritten every time the module
+-- is started.
+--
+-- This module can also be used programmatically:
+--

+--
+-- Copyright (C) 2005-2025 Mike Pall. All rights reserved.
+-- Released under the MIT license. See Copyright Notice in luajit.h
+----------------------------------------------------------------------------
+--
+-- This module can be used to debug the JIT compiler itself. It dumps the
+-- code representations and structures used in various compiler stages.
+--
+-- Example usage:
+--
+--   luajit -jdump -e "local x=0; for i=1,1e6 do x=x+i end; print(x)"
+--   luajit -jdump=im -e "for i=1,1000 do for j=1,1000 do end end" | less -R
+--   luajit -jdump=is myapp.lua | less -R
+--   luajit -jdump=-b myapp.lua
+--   luajit -jdump=+aH,myapp.html myapp.lua
+--   luajit -jdump=ixT,myapp.dump myapp.lua
+--
+-- The first argument specifies the dump mode. The second argument gives
+-- the output file name. Default output is to stdout, unless the environment
+-- variable LUAJIT_DUMPFILE is set. The file is overwritten every time the
+-- module is started.
+--
+-- Different features can be turned on or off with the dump mode. If the
+-- mode starts with a '+', the following features are added to the default
+-- set of features; a '-' removes them. Otherwise the features are replaced.
+--
+-- The following dump features are available (* marks the default):
+--
+--  * t  Print a line for each started, ended or aborted trace (see also -jv).
+--  * b  Dump the traced bytecode.
+--  * i  Dump the IR (intermediate representation).
+--    r  Augment the IR with register/stack slots.
+--    s  Dump the snapshot map.
+--  * m  Dump the generated machine code.
+--    x  Print each taken trace exit.
+--    X  Print each taken trace exit and the contents of all registers.
+--    a  Print the IR of aborted traces, too.
+--
+-- The output format can be set with the following characters:
+--
+--    T  Plain text output.
+--    A  ANSI-colored text output
+--    H  Colorized HTML + CSS output.
+--
+-- The default output format is plain text. It's set to ANSI-colored text
+-- if the COLORTERM variable is set. Note: this is independent of any output
+-- redirection, which is actually considered a feature.
+--
+-- You probably want to use less -R to enjoy viewing ANSI-colored text from
+-- a pipe or a file. Add this to your ~/.bashrc: export LESS="-R"

+--   <number> stack dump depth (callee < caller). Default: 1.
+--   -<number> Inverse stack dump depth (caller > callee).
+--   s  Split stack dump after first stack level. Implies abs(depth) >= 2.

+----------------------------------------------------------------------------
+--
+-- This module shows verbose information about the progress of the
+-- JIT compiler. It prints one line for each generated trace. This module
+-- is useful to see which code has been compiled or where the compiler
+-- punts and falls back to the interpreter.
+--
+-- Example usage:
+--
+--   luajit -jv -e "for i=1,1000 do for j=1,1000 do end end"
+--   luajit -jv=myapp.out myapp.lua
+--
+-- Default output is to stderr. To redirect the output to a file, pass a
+-- filename as an argument (use '-' for stdout) or set the environment
+-- variable LUAJIT_VERBOSEFILE. The file is overwritten every time the
+-- module is started.
+--
+-- The output from the first example should look like this:
+--
+-- [TRACE   1 (command line):1 loop]
+-- [TRACE   2 (1/3) (command line):1 -> 1]
+--
+-- The first number in each line is the internal trace number. Next are
+-- the file name ('(command line)') and the line number (':1') where the
+-- trace has started. Side traces also show the parent trace number and
+-- the exit number where they are attached to in parentheses ('(1/3)').
+-- An arrow at the end shows where the trace links to ('-> 1'), unless
+-- it loops to itself.
+--
+-- In this case the inner loop gets hot and is traced first, generating
+-- a root trace. Then the last exit from the 1st trace gets hot, too,
+-- and triggers generation of the 2nd trace. The side trace follows the
+-- path along the outer loop and *around* the inner loop, back to its
+-- start, and then links to the 1st trace. Yes, this may seem unusual,
+-- if you know how traditional compilers work. Trace compilers are full
+-- of surprises like this -- have fun! :-)
+--
+-- Aborted traces are shown like this:
+--
+-- [TRACE --- foo.lua:44 -- leaving loop in root trace at foo:lua:50]
+--
+-- Don't worry -- trace aborts are quite common, even in programs which
+-- can be fully compiled. The compiler may retry several times until it
+-- finds a suitable trace.
+--
+-- Of course this doesn't work with features that are not-yet-implemented
+-- (NYI error messages). The VM simply falls back to the interpreter. This
+-- may not matter at all if the particular trace is not very high up in
+-- the CPU usage profile. Oh, and the interpreter is quite fast, too.

+.SH NAME
+luajit \- Just-In-Time Compiler for the Lua Language
+\fB
+.SH SYNOPSIS
+.B luajit
+[\fIoptions\fR]... [\fIscript\fR [\fIargs\fR]...]
+.SH "WEB SITE"
+.IR https://luajit.org
+.SH DESCRIPTION
+.PP
+This is the command-line program to run Lua programs with \fBLuaJIT\fR.
+.PP
+\fBLuaJIT\fR is a just-in-time (JIT) compiler for the Lua language.
+The virtual machine (VM) is based on a fast interpreter combined with
+a trace compiler. It can significantly improve the performance of Lua programs.
+.PP
+\fBLuaJIT\fR is API\- and ABI-compatible with the VM of the standard
+Lua\ 5.1 interpreter. When embedding the VM into an application,
+the built library can be used as a drop-in replacement.
+.SH OPTIONS
+.TP
+.BI "\-e " chunk
+Run the given chunk of Lua code.
+.TP
+.BI "\-l " library
+Load the named library, just like \fBrequire("\fR\fIlibrary\fR\fB")\fR.
+.TP
+.BI "\-b " ...
+Save or list bytecode. Run without arguments to get help on options.
+.TP
+.BI "\-j " command
+Perform LuaJIT control command (optional space after \fB\-j\fR).
+.TP
+.BI "\-O" [opt]
+Control LuaJIT optimizations.
+.TP
+.B "\-i"
+Run in interactive mode.
+.TP
+.B "\-v"
+Show \fBLuaJIT\fR version.
+.TP
+.B "\-E"
+Ignore environment variables.
+.TP
+.B "\-\-"
+Stop processing options.
+.TP
+.B "\-"
+Read script from stdin instead.
+.PP
+After all options are processed, the given \fIscript\fR is run.
+The arguments are passed in the global \fIarg\fR table.
+.PP
+Interactive mode is only entered, if no \fIscript\fR and no \fB\-e\fR
+option is given. Interactive mode can be left with EOF (\fICtrl\-Z\fB).
+.SH EXAMPLES
+.TP
+luajit hello.lua world
+
+Prints "Hello world", assuming \fIhello.lua\fR contains:
+.br
+  print("Hello", arg[1])
+.TP
+luajit \-e "local x=0; for i=1,1e9 do x=x+i end; print(x)"
+
+Calculates the sum of the numbers from 1 to 1000000000.
+.br
+And finishes in a reasonable amount of time, too.
+.TP
+luajit \-jv \-e "for i=1,10 do for j=1,10 do for k=1,100 do end end end"
+
+Runs some nested loops and shows the resulting traces.
