% \begin{implementation}
% \noindent I initialise the package with basic information.
%    \begin{macrocode}
%<*marathi>
\ProvidesExplPackage{linguistix-marathi}
                    {2026-04-27}
                    {v0.9b}
                    {मराठी (Marathi)}
%    \end{macrocode}
% Average height of Marathi conjuncts could be more than
% that of Latin letters with descenders. This requires minor
% adjustments in the baseline stretch. To do it uniformly
% for footnotes also, I use the \pkg{setspace} package (if
% not loaded already).
%    \begin{macrocode}

\IfPackageLoadedF { setspace } {
  \RequirePackage { setspace }
}
%    \end{macrocode}
% We need to set the spacing between lines and words for
% which I use internal floating point numbers. They are
% declared here.
%    \begin{macrocode}

\fp_gzero_new:N \g_मराठी_शब्दांतील_अंतर_fp
\fp_gzero_new:N \g_मराठी_ओळींतील_अंतर_fp
%    \end{macrocode}
% This macro grabs an argument and passes it to the key
% |शब्दांतील अंतर| which is used to set the inter-word space
% for Marathi.
%    \begin{macrocode}

\cs_new_protected:Npn \मराठी_शब्दांतील_अंतर:n #1 {
  \lngx_set_keys:n { शब्दांतील~ अंतर = { #1 } }
}

\cs_gset_eq:NN \शब्दांतीलअंतर \मराठी_शब्दांतील_अंतर:n
%    \end{macrocode}
% This macro grabs an argument, (g-)sets it as the value of
% \cs{g_मराठी_ओळींतील_अंतर_fp} and resets the baseline stretch
% with \cs{setstretch} command. If the current class is
% \cls{memoir}, then there is a method to do that without
% any package. I use that.
%    \begin{macrocode}

\cs_new_protected:Npn \मराठी_ओळींतील_अंतर:n #1 {
  \fp_gset:Nn \g_मराठी_ओळींतील_अंतर_fp { #1 }
  \IfClassLoadedTF { memoir } {
    \setSingleSpace {
      \fp_use:N \g_मराठी_ओळींतील_अंतर_fp
    }
    \SingleSpacing
  } {
    \setstretch {
      \fp_use:N \g_मराठी_ओळींतील_अंतर_fp
    }
  }
}

\cs_gset_eq:NN \ओळींतीलअंतर \मराठी_ओळींतील_अंतर:n
%    \end{macrocode}
% Here I define two keys for adjusting the space between
% words and lines respectively. Their defaults are also set
% here.
%    \begin{macrocode}

\keys_define:nn { मराठी } {
  शब्दांतील~ अंतर
  .fp_gset:N             = \g_मराठी_शब्दांतील_अंतर_fp,
  शब्दांतील~ अंतर
  .initial:n             = { 1.25 },
  ओळींतील~ अंतर
  .code:n                = {
    \मराठी_ओळींतील_अंतर:n { #1 }
  }
}
%    \end{macrocode}
% The \pkg{babel} package defines |\extrasxxxx| commands for
% languages where the additional code that should go with a
% particular language (|xxxx| in this case) is set. The
% |\addto| command is used for appending to the same. I
% start with defining additional macros for Marathi.
%    \begin{macrocode}

\addto { \extrasmarathi } {
%    \end{macrocode}
% I have added the command for using the socket for native
% numbering. It will pickup its value from the current
% assignment of the plugs and produce the results
% accordingly.
%    \begin{macrocode}
  \socket_use:n { lngx / native-numbering }
%    \end{macrocode}
% By default, \LaTeX\ prints roman numeral (in capital) as
% part numbers. They are not suitable for Marathi. Thus we
% change them to be printed with \cs{lngx_counter:n}
% instead.
%    \begin{macrocode}
  \cs_set:Npn \thepart { \lngx_counter:n { part } }
%    \end{macrocode}
% The default \LaTeX\ produces Latin numerals, roman (small
% and capital both) alphabets and a-z alphabets with
% enumerate at different levels of nesting. In Marathi, both
% are irrelevant. Thus I renew all of the concerned commands
% and change them to print Marathi numbers. Since Marathi
% doesn’t have much variety available for counters, I have
% chosen a simpler style, i.e. 1, 1.1, 1.1.1 and 1.1.1.1.
%    \begin{macrocode}
  \cs_set:Npn \theenumi { \lngx_counter:n { enumi } }
  \cs_set:Npn \theenumii {
    \lngx_counter:n { enumi } .
    \lngx_counter:n { enumii }
  }
%    \end{macrocode}
% A period is added after each ‘label’ in enumerate. In
% default \LaTeX, the label for second level enumeration is
% printed inside brackets. We don’t need it in Marathi. So
% I change the \cs{labelenumii} command and add a period.
% It is not added for the first level because that’s
% \LaTeX-default too. Similarly, this is extended to all the
% other levels.
%    \begin{macrocode}
  \cs_set:Npn \labelenumii { \theenumii . }
  \cs_set:Npn \theenumiii {
    \lngx_counter:n { enumi } .
    \lngx_counter:n { enumii } .
    \lngx_counter:n { enumiii }
  }
  \cs_set:Npn \labelenumiii { \theenumiii . }
  \cs_set:Npn \theenumiv {
    \lngx_counter:n { enumi } .
    \lngx_counter:n { enumii } .
    \lngx_counter:n { enumiii } .
    \lngx_counter:n { enumiv }
  }
  \cs_set:Npn \labelenumiv { \theenumiv . }
%    \end{macrocode}
% The \pkg{expex} package has an independent mechanism of
% defining and using counters. I define a set called
% |देवनागरी| here and make it the default when Marathi is
% used. Note that this change will go with the
% \cs{lngx_misc_reset:} command. Refer to |linguistix.pdf|
% for more information on this.
%    \begin{macrocode}
  \IfPackageLoadedT { expex } {
    \definelabeltype { देवनागरी } {
      labelgen                 = { list },
      labellist                = {
        अ, आ, इ, ई,
        उ, ऊ, ए, ऐ,
        ओ, औ, अं, अः,
        ॲ, ऋ, ॠ, ऌ, ॡ, ऑ
      },

    }
    \lingset {
      labeltype                = { देवनागरी }
    }
  }
%    \end{macrocode}
% Marathi doesn’t distinguish between Italic and Upright. So
% I redefine \cs{emph} to produce the argument in bold
% instead. This also goes when \cs{lngx_misc_reset:} is
% used.
%    \begin{macrocode}
  \cs_gset_eq:NN \emph \textbf

%    \end{macrocode}
% With the following code, I add the date conversion
% settings and the parameters to |onchar| command inside
% \cs{babelprovide}. This is done only if Marathi is the
% main language of the document. I also set the numbering
% style to |strict|ly native if Marathi is the main
% language.
%    \begin{macrocode}

\tl_if_eq:NnTF \g_lngx_main_language_tl { marathi } {
