[Tex/LaTex] How to input current date directly from datetime to pgfgantt

datetimepgfgantt

I would like to input the current date taken from "datetime" into the "pgfgantt" package to update the date bar automatically at compilation.

The date seems to be in the correct format,
however when input to pgfgantt, it throws an error:

! Use of \\ganttchart doesn't match its definition.
\new@ifnextchar ...served@d = #1\def \reserved@a {
                                                  #2}\def \reserved@b {#3}\f...
l.23 ]{2014-06-01}{2014-07-30}

Working code is here (replace "today=2014-06-02" with "today=\dashdate\today" to reproduce error):

\documentclass[a4paper,10pt]{report}

\usepackage[pdftex,active,tightpage]{preview}
\setlength\PreviewBorder{2mm}
\usepackage{pgfgantt}
\usepackage{pgfcalendar}
\usepackage{ifthen}
\usepackage{datetime}

\newdateformat{dashdate}{\THEYEAR-\twodigit{\THEMONTH}-\twodigit{\THEDAY}}
%\dashdate\today

\begin{document}
\begin{preview}

\begin{ganttchart}[x unit=.3cm, hgrid,vgrid={dotted},time slot format=isodate,
today=
2014-06-02, %replace "2014-06-02" with "\dashdate\today" to reproduce error
today offset=.5,
today label=Current Date,
today label node/.append style={anchor=north west},
today label font=\itshape\color{red},today rule/.style={draw=blue, ultra thick}
]{2014-06-01}{2014-07-30}
\gantttitlecalendar{year, month=name, week} \\
\ganttbar{Task-1.1}{2014-06-01}{2014-06-03} \\
\ganttbar{Task-1.2}{2014-06-03}{2014-06-06} \\
\ganttmilestone{Milestone 1}{2014-06-06} 

\end{ganttchart}
\end{preview}
\end{document}

Any ideas how I can make this work?

You can use today=\the\year-\the\month-\the\day.

[Tex/LaTex] Print current date without updating

I've seen so many crazy things made with LaTeX, i wouldn't say that something is impossible, but you have to use LuaLaTeX for my solution.

At first make a file,call it datetime.lua and add the following line.

datetime.lua

t = {}

All dates are saved in a lua table. You can edit them later in this file.

main.tex

\documentclass{scrartcl}
\usepackage{luacode}

\begin{luacode}
 require("datetime")

 function getdate(c)
  d = os.date("%d %B, %Y")   
   if (c <= #t) then
    tex.print(t[c])
   else
    file = io.open("datetime.lua", "a")
    file:write("t[".. c .."] = '" .. d .. "'; ")
    file:flush()
    file:close()
    tex.print(d)
   end
 end
\end{luacode}

\newcounter{date}
\addtocounter{date}{1}

\newcommand{\customdate}{\directlua{getdate(\number\value{date})}\stepcounter{date}}

\begin{document}

\customdate

\end{document}

I am using a counter to make a referenz to the date position. The value is passed to a simple lua function. If the date is already saved, it is loaded from the table and if not, it is written to the datetime file and the current date is printed.

Edit: You can get a problem when you change the order. (reorder the numbers in datetime.lua)

[Tex/LaTex] How to make a new date format with abbreviated names of months with the datetime package

With datetime dates can be stored to a symbolic name, say 'mydate' with \newsavedate{mydate}{daynumber}{monthnumber}{yearnumber}

\displaydate{mydate} will display this date using the current date format, whereas \getdatemonth{mydate} will extract the month of the saved date.

Using \shortmonthname[\getdatemonth{mydate}] it's possible to show the 3-letter abbreviation of the month (see the example)

\documentclass{article}

\usepackage{datetime}

\usepackage{xcolor}
\newdate{mydate}{23}{10}{2015}

\begin{document}
Not today: \displaydate{mydate}

The month of \displaydate{mydate} is \textcolor{red}{\shortmonthname[\getdatemonth{mydate}]}

\end{document}

Update

Using a \newdateformat any call to \mydateformat will show this format, that's why a 'wrapper macro' (or grouping) is appropiate:

\documentclass{article}

\usepackage{datetime}

\newdateformat{mydateformat}{\shortmonthname[\THEMONTH]. \THEDAY}
\newcommand{\myshortformat}[1]{%
{% group here!
  \mydateformat%
  \displaydate{#1}%
}%
}


\usepackage{xcolor}
\newdate{mydate}{23}{10}{2015}

\begin{document}
Not today: \displaydate{mydate}

The month of \displaydate{mydate} is \textcolor{red}{\shortmonthname[\getdatemonth{mydate}]}

The saved date was in (short format): \myshortformat{mydate}

Today is: \today

\end{document}
