If you are using TeXLive on your linux workstations you may use texlive-full portable installed in:

/opt/texlive

There are folders for several years backward up to the latest distribution.

In order to use the shared TeX binaries from the command line, you may want to add the following line to your .bashrc:

export PATH=/opt/texlive/2018/bin/x86_64-linux/:$PATH

You may use this config file for setting up texstudio to use version from 2018.

• For the redefining the header, you can use
  • \markboth – two parameters (left and right page) or \markright with just one parameter
    • \markboth{\uppercase{Summary}}{\uppercase{Summary}}
    • You should note that a left-hand heading is generated by the last \markboth command before the end of the page, while a right-hand heading is generated by the first \markboth or \markright that comes on the page if there is one, otherwise by the last one before the page. (source)
  • \chaptermark, \sectionmark, … with fancyhdr package
  • see http://en.wikibooks.org/wiki/LaTeX/Page_Layout for more details

• Useful page (and a figure) for lists:
  • http://latex.computersci.org/Reference/ListEnvironments

• The if condition in TeX:
  • construction if \variable is empty:
    • The variable \if#\variable# is empty.\else contains \variable.\fi
      (\variable naturally cannot contain '#')
    • The variable \ifx\@empty\variable is empty.\else contains \variable.\fi
  • comparing two strings:

          \newif\ifsame
          \newcommand{\strcfstr}[2]{%
           \samefalse
           \begingroup
            \def\1{#1}\def\2{#2}%
            \ifx\1\2\endgroup \sametrue
            \else   \endgroup
            \fi
          }

    • (The grouping is needed there to make '\1' and '\2' local but '\sametrue' global.)
    • (source, Peter Wilson)
  • allocator \newif is used in a sequention:
    a declaration \newif\ifsomething
    setting either \somethingtrue or \somethingfalse
    and asking \ifsomething YES\else NO\fi

• foreach in TeX (thanks to TMA):
  • If you want to \dothis{} with each word in \foreach{Peter, Paul, John, Ringo}, you can do this as follows:
    • \def\foreach#1{\first#1,,}
    • \def\first#1,{\if,#1,\else\dothis{#1}\expandafter\first\fi}
  • and then write something here:
    • \def\dothis#1{ … whatever #1 … }

• Aligning an element in the line according to whether it fits in the rest of the line (TeX)
  • always right-aligned (from Petr Olšák's TeXbook naruby):

            \def\alignelemright #1\par{\unskip
              \nobreak\hfill\penalty71\hskip2em\hbox{}\nobreak\hfill
              \hbox{#1}\par}

  • always left-aligned:

            \def\alignelemleft #1\par{\unskip
              \hbox{} \hskip 0pt plus 1fil \penalty0
              \hbox{#1}\hskip 0pt plus 1fill\hbox{}\par}

  • align to the right, if it fits, or to the left in the new line:

           \def\alignelemrightorleft #1\par{\unskip
              \nobreak\hfill\penalty71\hskip2em
              \hbox{#1}\par}

• Two tables/figures side-by-side (source):

      \begin{figure}
       \begin{minipage}[b]{0.5\linewidth}
        \centering \includegraphics[scale=1]{fn1} \caption{c} \label{f1}
       \end{minipage}
       \hspace{0.5cm}
       \begin{minipage}[b]{0.5\linewidth}
        \centering \includegraphics[scale=1]{fn2} \caption{c} \label{f2}
       \end{minipage}
      \end{figure}

• Include completed PDF and add page numbers and other headings: \usepackage{pdfpages}

      % settings
      \markright{Author Name}    % or e.g. package fancyhdr
      \setcounter{page}{13}      % number of first page
      % inserting (first page with pagenumber in the foot, others in the head with author name)
      \includepdf[pages=1, pagecommand={\thispagestyle{plain}}]{file.pdf}
      \includepdf[pages=2-, pagecommand={\thispagestyle{myheadings}}]{file.pdf}

• \textwidth, \linewidth, \columnwidth, \hsize and others explained here (You want \linewidth in most cases.)
• Useful packages:
  • Source printing: fancyvrb, listings
  • fancyhdr
  • pseudocode algorithmicx
  • trees: xytree (complicated), dtree (Obo, pstricks), xyling (Martin P., \B and \T must be relaxed)
  • tables: xtab (better than longtable or supertabular), tabulary (pretty wrapped text in autosized cells, similar to tabularx), booktabs (no vertical lines, \toprule, \midrule/\cmidrule, \bottomrule instead of \hline/\cline) (all from this compendium)
• longtable or xtabular environment cannot be inside table environment. (Put it inside center instead, since you cannot use \centering as before.)
• Higher cells/rows in tables can be achieved either by booktabs package, or (if you have to use vertical lines in tables) by inserting \toppadding and \bottompadding in every row:

      \newcommand\toppadding{\rule{0pt}{2.6ex}}
      \newcommand\bottompadding{\rule[-1.2ex]{0pt}{0pt}}
      ...
      \hline
      \toppadding First cell\bottompadding & Second cell & Third one \\
      \hline
      ...

• hyperref package:
  • If some links from ToC point to incorrect objects (e.g. section III.2.5 points to the page where the section I.2.5 starts), then the problem is in internal hyperref naming convention (both section in the example are represented as 'section.2.5'). You can change it either by
    • naturalnames=true (⇒ 'section.III.2.5'), or
    • hypertexnames=false (⇒ 'section.289')
• New type of float and its List of

     \usepackage{tocloft} 
     \newlistof{graphs}{grp}{List of Graphs}                     % new list, file extension, its name
       \renewcommand{\cftgrptitlefont}{\sffamily\bfseries\huge}  % style of list title
       \setlength{\cftbeforegrptitleskip}{10ex}                  % space above list title
       \setlength{\cftaftergrptitleskip}{4ex}                    % space below list title
       % previous three lines alternatively (in pbmlbook class): \cfttitleset{grp}
     \newlistentry{graph}{grp}{0}                                % one line of the list (because it will be of type 'graph', not 'graphs', due to float named 'graph')
       \renewcommand{\cftgraphfont}{\sffamily}                   % entry style
       \renewcommand{\cftgraphpagefont}{\sffamily}               % page number style
       \setlength{\cftgraphnumwidth}{2em}                        % space for graph number
       % previous three lines alternatively (in pbmlbook class): \cftlineset{graph}{}{2em}
  
     \usepackage{float} 
     \newfloat{graph}{ht!}{grp}                                  % new float environment {graph}, "place it here or at the top of page" by default
       \floatname{graph}{Graph}                                  % each caption is started as "Graph \thegraph: <captioin>"
     ...
