  1. LaTeX Document Structure<\/strong><\/li>\r\n<\/ol>\r\n \r\n

    In the previous module we got familiarized with LaTeX typesetting system. We studied the LaTeX document structure which comprises of preamble and body sections. The preamble section is used to identify the type of document we want to create and the packages that are required to create documents. For example, suppose if we want to use Hindi fonts with LaTeX then we will use a package that supports Hindi fonts. Packages are available to provide enhancements to our LaTeX document.<\/p>\r\n \r\n\r\nBody of LaTeX Document<\/strong>\r\n\r\n \r\n

    Now, let us focus on the body of LaTeX document structure. The body section is divided into three parts, top matter, main matter and the back matter. Let us explore each of these sections.<\/p>\r\n \r\n\r\nTop Matter<\/strong>\r\n\r\n \r\n

    This section contains introduction to the document, details like title, author, creation date, abstract or executive summary, etc. The following is an example of top matter in LaTeX:<\/p>\r\n

    \"\"<\/p>\r\n

    By default, LaTeX will use the word \"Abstract\" as a title for our abstract. If we want to change it into anything else, e.g. \"Executive Summary\", we add the following line before we begin the abstract environment:<\/p>\r\n\\renewcommand{\\abstractname}{Executive Summary}\r\n\r\n \r\n\r\nMain Matter of the LaTeX Document<\/strong>\r\n\r\n \r\n

    The main content of document generally goes in the body section of LaTeX document structure. Usually the text that makes chapters or main content is written here. Following LaTeX commands are used in the body of any document:<\/p>\r\n

    \"\"<\/p>\r\n

    Let us see a LaTeX code where both the preamble and body are used together. The LaTeX code and its output is shown in figure 1 where the document contains chapter, section and subsection. It must be noted that we are not supplying chapter number or section number. These numbers will be placed automatically by LaTeX depending on the settings (commands) given earlier.<\/p>\r\n \r\n

    \"\"<\/p>\r\n

    Figure 2: Output of code shown in figure 1<\/strong><\/p>\r\nBack matter of LaTeX Document<\/strong>\r\n\r\n \r\n

    The back matter usually comprises of bibliography and index. If we have added citations in the main matter using commands like \\cite, \\cite[p.100], in that case, the bibliography can be automatically constructed during compilation using the following LaTeX commands:<\/p>\r\n

    \"\"<\/p>\r\nFormatting fonts in LaTeX<\/strong>\r\n\r\n \r\n

    LaTeX provides commands to format fonts. We can select font by specifying a package, apart from this, the style of font and its size can be specified using various commands. The list of commands and its effect is shown in following table:<\/p>\r\n

    \"\"<\/p>\r\n

    The font size can also be modified using commands like \\tiny\u2026 \\Huge; a list of commands is given in extra reading notes.<\/p>\r\n \r\n\r\nCreating Wrapper Commands in LaTeX<\/strong>\r\n

    We can create our own customized commands with the help \\newcommand in LaTeX. Such commands are known as wrapper commands. Wrapper commands are used to ease our task of typing difficult commands or longer commands. It is like aliasing a command so that we can use it easily. In LaTeX, \\newcommand can define a logical wrapper command. An example of using wrapper command and its output is shown below:<\/p>\r\n

    \"\"<\/p>\r\n \r\n\r\nUsing Environment in LaTeX<\/strong>\r\n\r\n \r\n

    Environments are used to format blocks of text in a LATEX documents. When we wish to apply common settings to multiple statements, environment can be used. The environment keyword is used to define a block as shown below:<\/p>\r\n

    \"\"<\/p>\r\n \r\n\r\nListing in LaTeX<\/strong>\r\n\r\n \r\n

    LaTeX provides commands to create lists. List structures in LaTeX are simply environments which essentially come in three types:<\/p>\r\n\r\n
