#+latex_class: my-article #+title: Simplenodes #+author: Bob Vergauwen #+date: 2022/03/31 | {{{examplenode(1,Simple)}}} | | | | | | {{{alertnode(2,simplenodes)}}} | | {{{simplenode(3,Nodes)}}} | | | {{{link(1,2)}}} {{{link(3,2)}}} * Introduction Creating tikz figures may be fun but after a while it becomes repetitive and you find yourself implementing the same repetitive patterns over and over again. This has a few negative effects on your daily productivity; - bad coding style by copy-pasting old solutions, - un-maintainable code, - repeating yourself over and over again, - inconsistent styles in a single document and over multiple documents. This package tries to solve these issues by providing two simple commands; - one command to create simple nodes, - one command to link these nodes. Some simple styling options can be changed upon loading the package. * Usage After including the package via the command #+BEGIN_EXAMPLE \usepackage{simplenodes} #+END_EXAMPLE all package commands are available. ** Creating a node Four different nodes are supported at the moment; | *Command* | *Result* | |-----------------------------+---------------------------------| | =\simplenode{name}{Normal}= | {{{simplenode(name,Normal)}}} | | =\examplenode{name}{Example}= | {{{examplenode(name,Example)}}} | | =\warnnode{name}{Warning}= | {{{warnnode(name,Warning)}}} | | =\alertnode{name}{Alert}= | {{{alertnode(name,Alert)}}} | The first parameter is the =name= used to link two nodes together. The third parameter is the =text= displayed inside the node. ** Linking nodes Linking nodes is done via the command =\link{name1}{name2}=, where the name is defined upon creating the node. ** Positioning nodes The intended use of this package is to position the nodes using the tabular environment. Nodes can be placed in cells of tables to create an easy and even layout. This usage is demonstrated in the examples. The usage of this package is not restricted to this usecase. * Package options A few packaged options are provided by using #+BEGIN_EXAMPLE \usepackage[name1=value1,name2=value2,...]{simplenodes} #+END_EXAMPLE The name, default value and description is provided in the following table | *Name* | *Default* | *Description* | |-----------+---------+-----------------------------------------------------| | =align= | center | Specifies the alignment of the text in the nodes. | | =width= | 25mm | The width of the nodes. | | =minheight= | 7mm | The minimum width of the nodes. | | =innersep= | 2pt | The inner separation between the text and the node. | | =outersep= | 0pt | The outer separation between the nodes. | | =thickness= | 0.4pt | The line thickness of the nodes and links. | * Examples ** Hello world | {{{simplenode(hello,hello)}}} | {{{simplenode(world,world)}}} | {{{link(hello,world)}}} #+begin_src latex :tangel no :exports code \begin{tabular}{ll} \simplenode{hello}{hello} & \simplenode{world}{world}\\ \end{tabular} \link{hello}{world} #+end_src ** More color | {{{simplenode(1,simple)}}} | {{{examplenode(2,example)}}} | {{{warnnode(3,warn)}}} | {{{alertnode(4,alert)}}} | {{{link(1,2)}}} {{{link(2,3)}}} {{{link(3,4)}}} #+begin_src latex :tangel no :exports code \begin{tabular}{llll} \simplenode{1}{simple} & \examplenode{2}{example} & \warnnode{3}{warn} & \alertnode{4}{alert}\\ \end{tabular} \link{1}{2} \link{2}{3} \link{3}{4} #+end_src ** Order of the arrows and doule arrows | {{{simplenode(1,node 1)}}} | {{{examplenode(2,node 2)}}} | {{{warnnode(3,node 3)}}} | {{{link(1,2)}}} {{{link(2,3)}}} {{{link(3,2)}}} #+begin_src latex :tangel no :exports code \begin{tabular}{lll} \simplenode{1}{node 1} & \examplenode{2}{node 2} & \warnnode{3}{node 3}\\ \end{tabular} \end{center} \link{1}{2} \link{2}{3} \link{3}{2} #+end_src ** Overly complex | {{{simplenode(11, Simple node)}}} | | | | {{{simplenode(13, Simple node)}}} | | | | | | | | {{{examplenode(21, Example node)}}} | | {{{alertnode(22,Alert node)}}} | | {{{simplenode(23, Simple node)}}} | | | | | | | | {{{warnnode(31, Warn node)}}} | | | | {{{simplenode(33, Simple node)}}} | | | | | | | {{{link(22,23)}}} {{{link(22,21)}}} {{{link(22,33)}}} {{{link(22,31)}}} {{{link(22,11)}}} {{{link(22,13)}}} {{{link(11,13)}}} {{{link(33,31)}}} {{{link(21,11)}}} {{{link(21,31)}}} {{{link(13,23)}}} {{{link(33,23)}}} #+begin_src latex :tangel no :exports code \begin{tabular}{lllll} \simplenode{11}{ Simple node} & & & & \simplenode{13}{ Simple node}\\ & & & & \\ \examplenode{21}{ Example node} & & \alertnode{22}{Alert node} & & \simplenode{23}{ Simple node}\\ & & & & \\ \warnnode{31}{ Warn node} & & & & \simplenode{33}{ Simple node}\\ & & & & \\ \end{tabular} \link{22}{23} \link{22}{21} \link{22}{33} \link{22}{31} \link{22}{11} \link{22}{13} \link{11}{13} \link{33}{31} \link{21}{11} \link{21}{31} \link{13}{23} \link{33}{23} #+end_src * Implementation #+BEGIN_SRC latex :exports code :tangle simplenodes.sty %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% simplenodes.sty %% %% %% MIT License %% %% Copyright (c) 2022 Bob Vergauwen %% %% Permission is hereby granted, free of charge, to any person obtaining a copy %% of this software and associated documentation files (the "Software"), to deal %% in the Software without restriction, including without limitation the rights %% to use, copy, modify, merge, publish, distribute, sublicense, and/or sell %% copies of the Software, and to permit persons to whom the Software is %% furnished to do so, subject to the following conditions: %% %% The above copyright notice and this permission notice shall be included in all %% copies or substantial portions of the Software. %% %% THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR %% IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, %% FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

The package provides two basic commands, one to generate a node and one command to create links between them. The positioning of the nodes is not handled by the package itself but is preferably done in the tabular environment. In total, 4 simple node types are defined, loosely based on the nomenclature and color patterns of the popular java script bootstrap (https://getbootstrap.com/). See the file `simplenodes.pdf` for more information on the possibilities and best use case of this package. See the file `LICENSE` for license details. ## Development This package is currently maintained by Bob Vergauwen, (bob@vergauwen.me).
