A tiny Java\+Script debugging utility modelled after Node.\+js core\textquotesingle{}s debugging technique. Works in Node.\+js and web browsers.\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12490}{}\doxysection{Installation}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12490}

\begin{DoxyCode}{0}
\DoxyCodeLine{\$ npm install debug }

\end{DoxyCode}
\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12491}{}\doxysection{Usage}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12491}
{\ttfamily debug} exposes a function; simply pass this function the name of your module, and it will return a decorated version of {\ttfamily console.\+error} for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.

Example \href{./examples/node/app.js}{\texttt{ {\itshape app.\+js}}}\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{var debug = require('debug')('http')}
\DoxyCodeLine{  , http = require('http')}
\DoxyCodeLine{  , name = 'My App';}
\DoxyCodeLine{}
\DoxyCodeLine{// fake app}
\DoxyCodeLine{}
\DoxyCodeLine{debug('booting \%o', name);}
\DoxyCodeLine{}
\DoxyCodeLine{http.createServer(function(req, res)\{}
\DoxyCodeLine{  debug(req.method + ' ' + req.url);}
\DoxyCodeLine{  res.end('hello\(\backslash\)n');}
\DoxyCodeLine{\}).listen(3000, function()\{}
\DoxyCodeLine{  debug('listening');}
\DoxyCodeLine{\});}
\DoxyCodeLine{}
\DoxyCodeLine{// fake worker of some kind}
\DoxyCodeLine{}
\DoxyCodeLine{require('./worker'); }

\end{DoxyCode}


Example \href{./examples/node/worker.js}{\texttt{ {\itshape worker.\+js}}}\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{var a = require('debug')('worker:a')}
\DoxyCodeLine{  , b = require('debug')('worker:b');}
\DoxyCodeLine{}
\DoxyCodeLine{function work() \{}
\DoxyCodeLine{  a('doing lots of uninteresting work');}
\DoxyCodeLine{  setTimeout(work, Math.random() * 1000);}
\DoxyCodeLine{\}}
\DoxyCodeLine{}
\DoxyCodeLine{work();}
\DoxyCodeLine{}
\DoxyCodeLine{function workb() \{}
\DoxyCodeLine{  b('doing some work');}
\DoxyCodeLine{  setTimeout(workb, Math.random() * 2000);}
\DoxyCodeLine{\}}
\DoxyCodeLine{}
\DoxyCodeLine{workb(); }

\end{DoxyCode}


The {\ttfamily DEBUG} environment variable is then used to enable these based on space or comma-\/delimited names.

Here are some examples\+:

  \hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12492}{}\doxysubsubsection{Windows command prompt notes}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12492}
\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12493}{}\doxyparagraph{CMD}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12493}
On Windows the environment variable is set using the {\ttfamily set} command.


\begin{DoxyCode}{0}
\DoxyCodeLine{set DEBUG=*,-\/not\_this }

\end{DoxyCode}


Example\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{set DEBUG=* \& node app.js }

\end{DoxyCode}
\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12494}{}\doxyparagraph{Power\+Shell (\+VS Code default)}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12494}
Power\+Shell uses different syntax to set environment variables.


\begin{DoxyCode}{0}
\DoxyCodeLine{\$env:DEBUG = "{}*,-\/not\_this"{} }

\end{DoxyCode}


Example\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{\$env:DEBUG='app';node app.js }

\end{DoxyCode}


Then, run the program to be debugged as usual.

npm script example\+: 
\begin{DoxyCode}{0}
\DoxyCodeLine{"{}windowsDebug"{}: "{}@powershell -\/Command \$env:DEBUG='*';node app.js"{}, }

\end{DoxyCode}
\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12495}{}\doxysection{Namespace Colors}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12495}
Every debug instance has a color generated for it based on its namespace name. This helps when visually parsing the debug output to identify which debug instance a debug line belongs to.\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12496}{}\doxysubsubsection{Node.\+js}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12496}
In Node.\+js, colors are enabled when stderr is a TTY. You also {\itshape should} install the \href{https://npmjs.org/supports-color}{\texttt{ {\ttfamily supports-\/color}}} module alongside debug, otherwise debug will only use a small handful of basic colors.

\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12497}{}\doxysubsubsection{Web Browser}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12497}
Colors are also enabled on \char`\"{}\+Web Inspectors\char`\"{} that understand the {\ttfamily c} formatting option. These are Web\+Kit web inspectors, Firefox (\href{https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/}{\texttt{ since version 31}}) and the Firebug plugin for Firefox (any version).

\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12498}{}\doxysection{Millisecond diff}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12498}
When actively developing an application it can be useful to see when the time spent between one {\ttfamily debug()} call and the next. Suppose for example you invoke {\ttfamily debug()} before requesting a resource, and after as well, the \char`\"{}+\+NNNms\char`\"{} will show you how much time was spent between calls.



When stdout is not a TTY, {\ttfamily Date\#to\+ISOString()} is used, making it more useful for logging the debug information as shown below\+:

\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12499}{}\doxysection{Conventions}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12499}
If you\textquotesingle{}re using this in one or more of your libraries, you {\itshape should} use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you {\itshape should} prefix them with your library name and use \char`\"{}\+:\char`\"{} to separate features. For example \char`\"{}body\+Parser\char`\"{} from Connect would then be \char`\"{}connect\+:body\+Parser\char`\"{}. If you append a \char`\"{}$\ast$\char`\"{} to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12500}{}\doxysection{Wildcards}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12500}
The {\ttfamily $\ast$} character may be used as a wildcard. Suppose for example your library has debuggers named \char`\"{}connect\+:body\+Parser\char`\"{}, \char`\"{}connect\+:compress\char`\"{}, \char`\"{}connect\+:session\char`\"{}, instead of listing all three with {\ttfamily DEBUG=connect\+:body\+Parser,connect\+:compress,connect\+:session}, you may simply do {\ttfamily DEBUG=connect\+:$\ast$}, or to run everything using this module simply use {\ttfamily DEBUG=$\ast$}.

You can also exclude specific debuggers by prefixing them with a \char`\"{}-\/\char`\"{} character. For example, {\ttfamily DEBUG=$\ast$,-\/connect\+:$\ast$} would include all debuggers except those starting with \char`\"{}connect\+:\char`\"{}.\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12501}{}\doxysection{Environment Variables}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12501}
When running through Node.\+js, you can set a few environment variables that will change the behavior of the debug logging\+:

\tabulinesep=1mm
\begin{longtabu}spread 0pt [c]{*{2}{|X[-1]}|}
\hline
\PBS\centering \cellcolor{\tableheadbgcolor}\textbf{ Name   }&\PBS\centering \cellcolor{\tableheadbgcolor}\textbf{ Purpose    }\\\cline{1-2}
\endfirsthead
\hline
\endfoot
\hline
\PBS\centering \cellcolor{\tableheadbgcolor}\textbf{ Name   }&\PBS\centering \cellcolor{\tableheadbgcolor}\textbf{ Purpose    }\\\cline{1-2}
\endhead
{\ttfamily DEBUG}   &Enables/disables specific debugging namespaces.    \\\cline{1-2}
{\ttfamily DEBUG\+\_\+\+HIDE\+\_\+\+DATE}   &Hide date from debug output (non-\/\+TTY).    \\\cline{1-2}
{\ttfamily DEBUG\+\_\+\+COLORS}   &Whether or not to use colors in the debug output.    \\\cline{1-2}

{\ttfamily DEBUG\+\_\+\+SHOW\+\_\+\+HIDDEN}   &Shows hidden properties on inspected objects.   \\\cline{1-2}
\end{longtabu}


{\bfseries{Note\+:}} The environment variables beginning with {\ttfamily DEBUG\+\_\+} end up being converted into an Options object that gets used with {\ttfamily o}/{\ttfamily O} formatters. See the Node.\+js documentation for \href{https://nodejs.org/api/util.html\#util_util_inspect_object_options}{\texttt{ {\ttfamily util.\+inspect()}}} for the complete list.\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12502}{}\doxysection{Formatters}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12502}
Debug uses \href{https://wikipedia.org/wiki/Printf_format_string}{\texttt{ printf-\/style}} formatting. Below are the officially supported formatters\+:

\tabulinesep=1mm
\begin{longtabu}spread 0pt [c]{*{2}{|X[-1]}|}

\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12503}{}\doxysubsection{Custom formatters}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12503}
You can add custom formatters by extending the {\ttfamily debug.\+formatters} object. For example, if you wanted to add support for rendering a Buffer as hex with {\ttfamily h}, you could do something like\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{const createDebug = require('debug')}
\DoxyCodeLine{createDebug.formatters.h = (v) => \{}
\DoxyCodeLine{  return v.toString('hex')}
\DoxyCodeLine{\}}
\DoxyCodeLine{}
\DoxyCodeLine{// …elsewhere}
\DoxyCodeLine{const debug = createDebug('foo')}
\DoxyCodeLine{debug('this is hex: \%h', new Buffer('hello world'))}
\DoxyCodeLine{//   foo this is hex: 68656c6c6f20776f726c6421 +0ms }

\end{DoxyCode}
\hypertarget{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12504}{}\doxysection{Browser Support}\label{md_sfcode_node_modules_https_proxy_agent_node_modules_debug_README_autotoc_md12504}
You can build a browser-\/ready script using \href{https://github.com/substack/node-browserify}{\texttt{ browserify}}, or just use the \href{https://wzrd.in/}{\texttt{ browserify-\/as-\/a-\/service}} \href{https://wzrd.in/standalone/debug@latest}{\texttt{ build}}, if you don\textquotesingle{}t want to build it yourself.

Debug\textquotesingle{}s enable state is currently persisted by {\ttfamily local\+Storage}. Consider the situation shown below where you have {\ttfamily worker\+:a} and {\ttfamily worker\+:b}, and wish to debug both. You can enable this using {\ttfamily local\+Storage.\+debug}\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{localStorage.debug = 'worker:*' }

\end{DoxyCode}


And then refresh the page.


\begin{DoxyCode}{0}
\DoxyCodeLine{a = debug('worker:a');}
\DoxyCodeLine{b = debug('worker:b');}
\DoxyCodeLine{}
\DoxyCodeLine{setInterval(function()\{}
\DoxyCodeLine{  a('doing some work');}
\DoxyCodeLine{\}, 1000);}
\DoxyCodeLine{}
\DoxyCodeLine{setInterval(function()\{}
\DoxyCodeLine{  b('doing some work');}
\DoxyCodeLine{\}, 1200); }

By default {\ttfamily debug} will log to stderr, however this can be configured per-\/namespace by overriding the {\ttfamily log} method\+:

Example \href{./examples/node/stdout.js}{\texttt{ {\itshape stdout.\+js}}}\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{var debug = require('debug');}
\DoxyCodeLine{var error = debug('app:error');}

\DoxyCodeLine{error('goes to stderr!');}
\DoxyCodeLine{}
\DoxyCodeLine{var log = debug('app:log');}
\DoxyCodeLine{// set this namespace to log via console.log}
\DoxyCodeLine{log.log = console.log.bind(console); // don't forget to bind to console!}
\DoxyCodeLine{log('goes to stdout');}
\DoxyCodeLine{error('still goes to stderr!');}
\DoxyCodeLine{}
\DoxyCodeLine{// set all output to go via console.info}
\DoxyCodeLine{// overrides all per-\/namespace log settings}
\DoxyCodeLine{debug.log = console.info.bind(console);}

You can also enable debug dynamically by calling the {\ttfamily enable()} method \+:


\begin{DoxyCode}{0}
\DoxyCodeLine{let debug = require('debug');}
\DoxyCodeLine{}
\DoxyCodeLine{console.log(1, debug.enabled('test'));}

\DoxyCodeLine{debug.disable();}
\DoxyCodeLine{console.log(3, debug.enabled('test'));}

\end{DoxyCode}


print \+: ~\newline
 
\begin{DoxyCode}{0}
\DoxyCodeLine{1 false}
\DoxyCodeLine{2 true}
\DoxyCodeLine{3 false }

\end{DoxyCode}


Usage \+: ~\newline
 {\ttfamily enable(namespaces)} ~\newline
 {\ttfamily namespaces} can include modes separated by a colon and wildcards.

Note that calling {\ttfamily enable()} completely overrides previously set DEBUG variable \+:


\begin{DoxyCode}{0}
\DoxyCodeLine{\$ DEBUG=foo node -\/e 'var dbg = require("{}debug"{}); dbg.enable("{}bar"{}); console.log(dbg.enabled("{}foo"{}))'}
\DoxyCodeLine{=> false }

After you\textquotesingle{}ve created a debug instance, you can determine whether or not it is enabled by checking the {\ttfamily enabled} property\+:


\begin{DoxyCode}{0}

\DoxyCodeLine{}
\DoxyCodeLine{if (debug.enabled) \{}
