NAME

    LaTeX::Easy::Templates - Easily format content into PDF/PS/DVI with
    LaTeX templates.

VERSION

    Version 0.06

SYNOPSIS

    This module provides functionality to format text content, living in a
    Perl data structure, into printer-ready documents (PDF/Postscript/DVI).
    It utilises the idea of Templates and employs the powerful LaTeX (via
    LaTeX::Driver) in order to format and render the final documents into
    printer feed.

    Its use requires that LaTeX is already installed in your system. Don't
    be alarmed! LaTeX is simple to install in any OS, see section
    "INSTALLING LaTeX" for how. In Linux it is provided by the system
    package manager.

    Using LaTeX will not only empower you like Guttenberg's press did and
    does, but it will also satisfy even the highest aesthetic standards
    with its 20/20 perfect typography. LaTeX is one of the rare cases where
    Software can be termed as Hardware. Install it and use it. Now.

    Here is a basic scenario borrowed from Dilbert's adventures. You have a
    number of emails with fields like sender, recipient, subject and
    content. This data can be represented in Perl as an array of hashes
    like:

      [
        {
          sender => 'jack',
          recipient => 'the clown',
          subject => 'hello',
          content => 'blah blah',
        },
        {
          sender => 'dede',
          recipient => 'kinski',
          subject => 'Paris rooftops',
          content => 'blah2 blah2',
        },
        ...
      ]

    You want to render this data to PDF.

    A more interesting scenario:

    You are scraping a, say, News website. You want each article rendered
    as PDF. Your scraper provides the following data for each News article,
    and you have lots of those:

      [
        {
          author => 'jack',
          title => '123',
          date => '12/12/2012',
          content => [
             'paragraph1',
             'paragraph2',
             ...
          ],
          comments => [
            {
              'author' => 'sappho',
              'content' => 'yearning ...',
           },
           ... # more comments
        }
        ... # more News articles
      ]

    Once you collect your data and save it into a Perl data structure as
    above (note: the stress is on structure) you need to create a templated
    LaTeX document which will be complete except that where the author,
    sender, recipient, content, etc. would be, you will place some tags
    like:

      <: $author :>
      <: $sender :>

    etc.

    The LaTeX::Easy::Templates module will then take your data and your
    LaTeX template and produce the final rendered documents.

    In section "STARTING WITH LaTeX" you will see how to easily build a
    LaTeX template from open source, publicly available, superbly styled
    "themes".

        use LaTeX::Easy::Templates;
    
        # templated LaTeX document in-memory
        # (with variables to be substituted)
        my $latex_template =<<'EOLA';
        % basic LaTeX document
        \documentclass[a4,12pt]{article}
        \begin{document}
        \title{ <: $data.title :> }
        \author{ <: $data.author.name :> <: $data.author.surname :> }
        \date{ <: $data.date :> }
        \maketitle
        <: $data.content :>
        \end{document}
        EOLA
    
        # my template variable substitutions
        my $template_data = {
          'title' => 'a test title',
          'author' => {
            'name' => 'myname',
            'surname' => 'surname',
          },
          'date' => '2024/12/12',
          'content' => 'blah blah',
        };
    
        my $latte = LaTeX::Easy::Templates->new({
          debug => {verbosity=>2, cleanup=>1},
          'processors' => {
            # if it includes other in-memory templates
            # then just include them here with their name
            'mytemplate' => {
              'template' => {
                'content' => $latex_template_string,
              },
              'output' => {
                'filepath' => 'output.pdf'
              }
            }
          }
        });
        die unless $latte;
    
        my $ret = $latter->format({
          'template-data' => $template_data,
          'outfile' => 'xyz.pdf',
          # this is the in-memory LaTeX template
          'processor' => 'mytemplate'
        });
        die unless $ret;

    In this way you can nicely and easily typeset your data into a PDF.

METHODS

 new()

    The constructor.

    The full list of arguments, provided as a hashref, is as follows:

      * processors : required parameter as a hash(ref) specifying one or
      more processors which are responsible for rendering the final typeset
      document from either a template or a LaTeX source file. The processor
      name is a key to the specified hash and should contain these items:

	* template : a hash(ref) containing information about the input
	LaTeX template. This information must be specified if no LaTeX
	source file is specified (see latex section below). Basically you
	need to specify the location of the LaTeX template file or a string
	with the contents of this template (as an in-memory template).

	Note that basedir and filename are explictly specified (instead of
	filepath) then **ALL CONTENTS** of basedir will be copied
	recursively to the output dir assuming that there are other files
	there (for example images, LaTeX style files etc.) which are needed
	during processing the template or running latex. If you do not want
	this file copying then just specify filepath.

	If there are other files or directories you will need during
	processing the template or running latex then you can specify them
	as an array(ref) in auxfiles. These will be copied recursively to
	the output dir.

	  * filepath : specify the full path to the template file, or,

	  * filename and basedir : specify a filename (not a file path) and
	  the directory it resides. Note that if you specify these two,
	  then **ALL CONTENTS** of basedir will be copied recursively to
	  the output dir assuming that there are other files there (for
	  example images, LaTeX style files etc.) which are needed during
	  processing the template or running latex.

	  * content : specify a string with the template contents. If this
	  template calls other templates (from disk) then you should
	  specify basedir to point to the path which holds these extra
	  files. In this case basedir can be an array(ref) with more than
	  one paths or just a scalar with a single path.

	  * auxfiles : specify a set of files or directories, as an
	  array(ref), to be copied recursively to the output dir. These
	  files may be needed for processing the template or for running
	  latex (for example, style files, images, other template files,
	  etc.). However, copying directories recursively can be pretty
	  heavy. So, there is an upper limit on the total file size of each
	  of the paths specified. This can be set during runtime with

             $self->max_size_for_filecopy(1024*1024);
             # or set it to negative for skipping all file size checks
             $self->max_size_for_filecopy(-1);

	* output : specifies the file path to the output typeset document:

	  * filepath : specify the full path to the output file, or,

	  * filename and basedir : specify a filename (not a file path) and
	  the directory it should reside.

	  Note that the path will be created if it does not exist.

	* latex : a hash(ref) containing information about the LaTeX source
	which will either be created from a LaTeX template (see template
	above) and some data for the template variables (more on this
	later) or be provided (the LaTeX source file) by the caller without
	any template.

	  * filepath : specify the full path to the LaTeX source file which
	  will be created from the template if the template parameter was
	  specified, or be used directly if no template was specified. In
	  the former case, the file may or may not exist on disk and will
	  be created. In the latter case, it must exist on disk.

	  * filename and basedir : specify a filename (not a file path) and
	  the directory it resides. Again, the LaTeX source file needs to
	  exist if no template parameter was specified.

	  * latex-driver-parameters : parameters in a hash(ref) to be
	  passed on to the LaTeX driver (LaTeX::Driver) which does the
	  actual rendering of the LaTeX source file into the typeset
	  printer-ready document. Refer to the documentation of
	  LaTeX::Driver's constructor for the description of each of the
	  parameters.

	  Note that only the following parameters will be passed on:

	    * format : specify the output format (e.g. pdf, ps, etc.) of
	    the rendered document and, optionally, the LaTeX "flavour" or
	    "processor" to be used, e.g. xelatex, pdflatex, latex, etc. The
	    default value is pdf(pdflatex).

	    * paths : specifies a mapping of program names to full pathname
	    as a hash reference. These paths override the paths determined
	    at installation time (of LaTeX::Driver).

	    * maxruns : The maximum number of runs of the formatter program
	    (defaults to 10 in LaTeX::Driver)

	    * extraruns : The number of additional runs of the formatter
	    program after the document has stabilized.

	    * timeout : Specifies a timeout in seconds within which any
	    commands spawned should finish. Even for very long documents
	    LaTeX is extremely fast, so this can be well under a minute.

	    * indexstyle : The name of a makeindex index style file that
	    should be passed to makeindex.

	    * indexoptions : Specifies additional options that should be
	    passed to makeindex. Useful options are: -c to compress
	    intermediate blanks in index keys, -l to specify letter
	    ordering rather than word ordering, -r to disable implicit
	    range formation. Refer to LaTeX's makeindex(1) for full
	    details.

	    * DEBUG : Enables debug statements if set to a non-zero value.
	    The value will be the same as our verbosity level.

	    * DEBUGPREFIX : Sets the debug prefix, which is prepended to
	    debug output if debug statements. By default there is no
	    prefix.

	  Note that the descriptions of the parameters (above) to be passed
	  on to LaTeX::Driver are taken more-or-less verbatim from its
	  documentation page, refer to the original document in case there
	  are changes.

	* latex : specify default parameters for processors' latex data in
	case it is absent:

	  * filename : default LaTeX source filename (not a filepath).

	  * latex-driver-parameters : default parameters to be passed on to
	  LaTeX::Driver's constructor. See above for what it includes.

	* debug :

	  * verbosity : script's verbosity. A value of zero mutes the
	  script. A higher integer increases the verbosity.

	  * cleanup : a non-zero value will clean up all temporary files
	  and directories including those created by LaTeX::Driver. This is
	  the default. For debugging purpose, set this to zero so that you
	  can inspect all intermediate files created.

	* tempdir : specify where the temporary files will be placed. This
	location will be created if it does not exist. Default is to use a
	temporary location as given by the OS.

	* logfile : specify a file to redirect the logger's output to.
	Default is to log messages to the console (STDOUT, STDERR).

	* logger_object : supply a Mojo::Log object to use as the logger.
	In fact any object implementing just these three: error(), warn()
	and info(), which Mojo::Log does, will be accepted.

	* templater-parameters : a HASH containing parameters to be passed
	on to the Text::Xslate constructor.

	These are some common templater paramaters:

	  * syntax : specify the template syntax to be either Kolon or
	  TTerse|Text::Xslate::Syntax::TTerse. Default is Kolon.

	  * suffix : specify the template files suffix. Default is .tx (do
	  not forget the dot).

	  * verbose : set the verbosity of Text::Xslate. Default is the
	  verbosity level currently set in the LaTeX::Easy::Templates
	  object.

	  * path : an array(ref) of paths to be searched for included
	  templates. This is crucial when templates are including other
	  templates in different directories.

	  * function, module : specify your own perl functions and modules
	  you want to use from within a template. That's very handy in
	  overcoming the limitations of the template syntax.

	See Text::Xslate#Text::Xslate-%3Enew(%options) for all the
	supported options.

	  * path : an array of paths to be searched for on-disk template
	  files which are dependencies, i.e. they are included by other
	  templates (in-memory or on-disk). This is very important if your
	  main template includes other templates which are in different
	  directories.

	  * syntax : the template syntax. Default is 'Kolon'.

	  * function, module : a hash of user-specified or built-in perl
	  functions (coderefs) to be used in the templates. And a list of
	  modules to be included for using these. Quite a powerful feature
	  of Text::Xslate.

	  * cache, cache_dir : cache level and location.

	  * line_start, tag_start, line_end, tag_end : the token strings
	  denoting the start and end of lines and tags.

	For example:

              'templater-parameters' => {
                # dependent templates search paths
                'path' => ['a/b/c', 'x/y/z', ...],
                # user-specified functions to be called
                # from a template
                'function' => {
                  'xyz' => sub { my (@params) = @_; ...; return ... }
                },
                ...
              },

    The constructor returns undef on failure.

    Here is example code for calling the constructor:

         use LaTeX::Easy::Template;
         my $latter = LaTeX::Easy::Template->new({
          'processors' => {
            'in-memory' => {
               'latex' => {
                    'filename' => undef # create tmp
               },
               'template' => {
                    # the template is in-memory string
                    'content' => '...'
               },
               'output' => {
                    'filename' => 'out.pdf'
               }
            }
            'on-disk' => {
              'latex' => {
                    'filename' => undef, # create tmp
               },
               'template' => {
                    'filepath' => 't/templates/simple01/main.tex.tx'
               },
               'output' => {
                    'filename' => 'out2.pdf'
               }
            }
          }, # end processors
          # log to this file, path will be created if not exists
          'logfile' => 'xyz/abc.log',
          'latex' => {
            'latex-driver-parameters' => {
               # we want PDF output run with xelatex which
               # easily supports multi-language documents
               'format' => 'pdf(xelatex)',
               'paths' => {
                  # the path to the xelatex needed only if not standard
                  'xelatex' => '/non-standard-path/xyz/xelatex'
               }
            }
          },
          'verbosity' => 1,
          'cleanup' => 0,
        });

    The above creates a LaTeX::Easy::Templates object which has 2
    "processors" one which uses a LaTeX template from disk and one
    in-memory. Default LaTeX::Driver parameters are specified as well and
    will be used for these processors which do not specify any.

 untemplate()

    It creates a LaTeX source file from a template. This is the first step
    in rendering the final typeset document. which is done by "format()".

    Note that calling this method is not necessary if you intend to call
    "format()" next. The latter will call the former if needed.

    The full list of arguments is as follows:

      * processor : specify the name of the "processor" to use. The
      "processor" must be a key to the processors parameter passed to the
      constructor.

      * template-data : specify the data for the template's variables as a
      hash or array ref, depending on the structure of the template in use.
      This data is passed on to the template using the key data. So if your
      template data is this:

        {
          name => 'aa',
        }

      Then your template will access name's value via  <: $data.name : >

      See "TEMPLATE PROCESSING" for more on the syntax of the template
      files.

      * latex, template : optionally, overwrite "processor"'s latex,
      template fields by specifying any of these fields here in exactly the
      same format as that of the processors parameter passed to the
      constructor ("new()").

    On failure, "untemplate()" returns undef.

    On success, it returns a hash(ref) with two entries:

      * latex : contains fileapth, filename and basedir of the produced
      LaTeX source file.

      * template : it contains fileapth, filename, basedir and content. The
      last one will be undefined if the template used if the template was a
      file read from disk. The first three will be undefined otherwise.

 format()

    It renders the final typeset document. It will call "untemplate()" if
    is required to produce the intermediate LaTeX source file. If that file
    was specified, then it will render the final document by calling
    LaTeX::Driver.

    The full list of arguments, provided by a hashref, is as follows:

      * processor : specify the name of the "processor" to use. The
      "processor" must be a key to the processors parameter passed to the
      constructor.

      * template-data : specify the data for the template's variables as a
      hash or array ref, depending on the structure of the template in use.
      This data is only needed if the intermediate LaTeX source file needs
      to be produced.

      * latex, template, output : optionally, overwrite "processor"'s
      latex, template, output fields by specifying any of these fields here
      in exactly the same format as that of the processors parameter passed
      to the constructor ("new()").

    On failure, "format()" returns undef.

    On success, it returns a hash(ref) with three entries:

      * latex : contains fileapth, filename and basedir of the produced
      LaTeX source file.

      * template : it contains fileapth, filename, basedir and content. The
      last one will be undefined if the template used if the template was a
      file read from disk. The first three will be undefined otherwise.

      * output : it contains fileapth, filename and basedir pointing to the
      output typeset document it created.

 max_size_for_filecopy($maxsize)

    It gets or sets (with optional parameter $maxsize) the maximum size for
    doing a recursive file copy. Recursive file copies are done for
    template extra files which may be needed for processing the template or
    running latex. They are specified if template->basedir is explicitly
    set (then the whole basedir will be copied) or when template->auxfiles
    are specified as an arrayref of files/dirs to copy individually. In
    order to reduce the risk of unintentionally copying vast files and
    directories there is a limit to the total (recursively calculated) size
    of files/directories to be copied. This can be set here. The default is
    3MB. However if you set this limit to a negative integer no checks will
    be make and file copying will be done unreservedly.

 verbosity($verbosity)

    It gets or sets (with optional parameter $verbosity) the verbosity
    level.

 cleanup($c)

    It gets or sets (with optional parameter $c) the cleanup parameter
    which contols the cleaning up of temporary files and directories or
    not. Set it to 1 to clean up. This is currently the default. Set it to
    0 to keep these files for inspection during debugging.

 templater($t)

    It gets or sets (with optional parameter $t) the templater object. This
    is the object which convertes the LaTeX template into LaTeX source.
    Currently only Text::Xslate is supported.

 templater_reset()

    Reset the templater object which means to forget all the templates it
    knows and had possibly loaded in memory. After a reset all "processors"
    will be forgotten as well.

 log($l)

    It gets or sets (with optional parameter $l) the logger object.
    Currently the logger is of type Mojo::Log.

 latex_driver_executable($program_name)

    This is an exported sub (and not a method)

    It enquires LaTeX::Driver for what is the fullpath to the program named
    $program_name. The program can be latex, dvips, makeindex, pdflatex
    etc. If the program is not found or if it is not an executable (for the
    current user), it returns undef. If it is found and it is executable
    (for the current user), its fullpath is returned.

    The parameter $program_name is optional, if it is omitted, it returns a
    hash(ref) with all known programs (the keys) and their full paths (the
    values).

    Note that LaTeX::Driver's paths are detected during its installation
    (according to its documentation).

    Program full paths can be set during running "format()" by passing it
    the parameter latex->latex-driver-parameters->paths (a hashref mapping
    program names to their paths).

 processors()

    It returns the hash(ref) of known "processors" as they were set up
    during construction.

 loaded_info()

    It returns the hash(ref) of extra information relating to the
    "processors".

TEMPLATE PROCESSING

    The LaTeX templates will be processed with Text::Xslate and must follow
    its rules. It understands two template syntaxes:

      * it's own Text::Xslate::Syntax::Kolon

      * and a subset of Template Toolkit 2 Text::Xslate::Syntax::TTerse

    The default syntax is Text::Xslate::Syntax::Kolon. This can be changed
    via the parameters to the constructor of LaTeX::Easy::Templates by
    specifying this:

      'templater-parameters' => {
          'syntax' => 'Kolon' #or 'TTerse'
      }

    The data for substituting into the template variables comes bundled
    into a hashref which comes bundled into a hashref keyed under the name
    "data". Therefore all references must be preceded by key data.

    So if your template data is this:

      {
        name => 'aa',
      }

    Then your template will access name's value via  <: $data.name : >.

    Text::Xslate supports loops and conditional statements. It also offers
    a lot of builtin functions. Additionally you can call user-specified
    perl subs (or subs from other modules) from within a template.

    Read the documentation for Text::Xslate's syntax
    Text::Xslate::Syntax::Kolon or Text::Xslate::Syntax::TTerse.

TEMPLATES INCLUDING TEMPLATES

    Templates which include other templates are supported.

    The included and the includee templates can be a combination of on-disk
    files and/or in-memory strings. Which means in-memory templates can
    include on-disk and vice-versa.

 In-memory templates

    The processor parameter to LaTeX::Easy::Templates's constructor should
    contain both the main template and all other included templates keyed
    on their include name. For example, the main template is:

        \documentclass[letterpaper,twoside,12pt]{article}
        \begin{document}
        : include "preamble.tex.tx" {data => $data};
        : for [1, 2, 3] -> $i {
          \section{Content for section <: $i :>}
          : include "content.tex.tx" {data => $data};
       : }
       \end{document}

    The above includes two other templates:

        :# preamble.tex.tx
        \title{ <: $data.title :> }
        \author{ <: $data.author.name :> <: $data.author.surname :> }
        \date{ <: $data.date :> }

    and

        :# content.tex.tx
        <: $data.content :>

    In order to load all above templates, construct the
    LaTeX::Easy::Templates object like this:

         my $latter = LaTeX::Easy::Template->new({
          'processors' => {
            # the main entry
            'main.tex.tx' => {
               'template' => {
                    'content' => '... main.tex.tx contents ...'
               },
               'output' => {
                    'filename' => 'out.pdf'
               }
            },
            # it includes these other templates:
            'preamble.tex.tx' => { # one ...
               'template' => {
                    'content' => '... preamble.tex.tx contents ...'
               }
            },
            'content.tex.tx' => { # ... and two
               'template' => {
                    'content' => '... content.tex.tx contents ...'
               },
            }
          } # end 'processors'

    With the above, all in-memory templates required are loaded in memory.
    All you need now is to specify "main.tex.tx" (which is the main entry
    point) as the processor name when calling "untemplate()" or "format()".
    You do not need to mention the included template names at all:

        my $ret = $latter->format({
          'template-data' => $template_data,
          'output' => {
            'filepath' => ...,
          },
          # just specify the main entry template
          'processor' => 'main.tex.tx',
    });

    The above functionality is demonstrated and tested in file
    t/460-inmemory-template-usage-calling-other-templates.t

 On-disk file templates

    If both the main template and all templates it includes are in the same
    directory then you only need to specify the main.tex.tx template under
    key processors in the parameters to LaTeX::Easy::Templates's
    constructor. In this case all dependencies will be taken care of (thank
    you Text::Xslate).

    Additionally, you can specify a list of directories as paths to be
    searched for dependent templates. These include paths can be passed on
    as parameters to LaTeX::Easy::Templates's constructor, under

         ...
         'templater-parameters' => {
           'path' => ['a/b/c', 'x/y/z', ...]
         },
         ...
    
         my $latter = LaTeX::Easy::Template->new({
           'templater-parameters' => {
             'path' => ['a/b/c', 'x/y/z', ...],
             ...
           },
           'processors' => {
            # the main entry
             'main.tex.tx' => {
               'template' => {
                 'filepath' => '/x/y/z/main.tex.tx'
                 # works also with specifying
                 #   'filename' & 'basedir'  
               },
               'output' => {
                    'filename' => 'out.pdf'
               }
             },
             # the dependent templates are not needed
             # to be included if in same dir
             # include them ONLY if in different dir
           } # end 'processors'
         }); # end constructor

    With the above, the "main.tex.tx" template, which is the main entry
    point, is loaded. As long as its dependencies, i.e. the templates it
    includes, are in the same directory or are specified with their full
    path, then there is nothing else you need to include. The dependencies
    will be found and included as needed.

    All you need now is to specify "main.tex.tx" as the processor name when
    calling "untemplate()" or "format()". You do not need to mention the
    included template names at all. Like this:

        my $ret = $latter->format({
          'template-data' => $template_data,
          'output' => {
            'filepath' => '/x/y/z/out.pdf',
          },
          # just specify the main entry template
          # dependencies will be included as needed:
          'processor' => 'main.tex.tx',
    });

    The above functionality is demonstrated and tested in file
    t/360-ondisk-template-usage-calling-other-templates.t

 Mixed use of in-memory and on-disk templates

    One can have a project of mixed, in-memory and on-disk, templates one
    including the other in any combination. This is straightforward, just
    follow the above guidelines.

    Mixed templates functionality is demonstrated and tested in file
    t/500-mix-template-usage-calling-other-mix-templates.t.

STARTING WITH LaTeX

    Currently, the best place to get started with LaTeX is at the site
    https://www.overleaf.com/ (which I am not affiliated in any way). There
    is no subscription involved or any registration required.

    Click on Templates <https://www.overleaf.com/latex/templates> and
    search for anything you are interested to typeset your data with. For
    example, if you are scraping a news website you may be interested in
    the Committee Times
    <https://www.overleaf.com/latex/templates/newspaper-slash-news-letter-template/wjxxhkxdjxhw>
    template. First check its license and if you agree with that, click on
    View Source, copy the contents and paste them into your new LaTeX file,
    let's call that main.tex located in a new directory
    templates/committee-times.

    Firstly, run latex on it with this command latex main.tex. It will fail
    if it can not find, in your LaTeX installation, the packages it
    requires. For example it requires package newspaper. If it complains
    that certain packages are not found, please read section "INSTALLING
    LaTeX PACKAGES".

    Now study that LaTeX source file and identify what template variables
    and control structures to use in order to turn it into a template.
    Rename the file to main.tex.tx and you are ready.

    Naturally, there will be a lot of head banging and hair pulling before
    you manage to produce anything decent.

LaTeX TEMPLATES

    Creating a LaTeX template is very easy. You need to start with a LaTeX
    document and identify those sections which can be replaced by the
    template variables. You can also identify repeated sections and replace
    them with loops. It is exactly the same procedure as with creating HTML
    templates or email messages templates.

    At this moment, the template processor is Text::Xslate. Therefore the
    syntax for declaring template variables, loops, conditionals, etc. must
    comply with Text::Xslate. See section "TEMPLATE PROCESSING" for where
    to start with Text::Xslate.

    A LaTeX template can live in memory as a Perl string or on disk, as a
    file in its own directory or not.

    If your template dependes on other templates you can include all as
    files in the same directory.

    If your template depends on your own LaTeX style files, packages etc.,
    then include those in the same directory with the LaTeX templates.
    Additionally, when specifying the location of the template, specify
    basedir and filename (instead of a single filepath). This will ensure
    that all file dependencies contained within basedir will be copied to
    the temporary processing directories. See "new()" for how this works.

INSTALLING LaTeX

    Today, as far as I know, there are two main TeX/LaTeX distributions:
    MikTeX <https://miktex.org/> and TexLive <https://www.tug.org/texlive/>

    Both provide the same LaTeX. They just package different things with
    it. And both provide package managers in order to make installing extra
    packages easy.

    I believe MikTeX <https://miktex.org/> was, at some time, aimed for M$
    systems and TexLive <https://www.tug.org/texlive/> for the saner
    operating systems.

    My Linux package manager installs TexLive
    <https://www.tug.org/texlive/> and I am absolutely happy with it.

INSTALLING LaTeX PACKAGES

    In Linux, it is preferred to install LaTeX packages via the system
    package manager.

    With modern TeX distributions installing LaTeX packages is quite
    simple. Both MikTeX <https://miktex.org/> and TexLive
    <https://www.tug.org/texlive/> provide package installers.

    See this guide
    <https://en.wikibooks.org/wiki/LaTeX/Installing_Extra_Packages#Automatic_installation>
    for more information.

 Manual installation

    This is the hard way.

    All available LaTeX packages are located at the Comprehensive TeX
    Archive Network (CTAN) site . Search the package, download it, locate
    and change to your LaTeX installation directory (for example
    /usr/share/texlive/texmf-dist), change to tex. Decide which flavour of
    LaTeX (processor) this package is for, e.g. latex, pdflatex or xelatex,
    change to that directory and unzip the downloaded file there.

TESTING

    Some tests may fail because some required LaTeX fonts and/or style
    files are missing from your LaTeX installation. As of version 0.04 the
    test files which use complex LaTeX formatting and may require extra
    LaTeX packages have been designated as author tests and have been moved
    to the xt/ directory. They are not part of the usual unit tests suite
    run with make test. They can be run using make authortest. If there are
    failures, try installing the missing LaTeX fonts and style files (see
    section "INSTALLING LaTeX PACKAGES"). Or freshen up your LaTeX
    installation. In any event, these tests are not important and their
    possible failure should not cause any convern.

    In order to run all tests download the tarball of this module, extract
    it, enter the directory and do:

        perl Makefile.PL
        make all
        make test
        make authortest
