LaTeX examples

utilities/code-with-output.tex

User Interface

• \begin{example}[tcb options]{title}, code followed by output, numbered
• \begin{example*}[tcb options]{title}, unnumbered variant

Typical configured usage

• side by side, \begin{example}[sidebyside]{title}
• change code language, \begin{example}[minted options app={language=python}]{title}

Internals

• direct dependencies:
  • tcolorbox, with libraries hooks, minted, skins and xparse loaded
  • accsupp
• environments are based on tcolorbox's minted library, -shell-escape required
• added
  • \emptyaccsupp
  • tcolorbox options example options and example title
• modified
  • \theFancyVerbLine

utilities/print-definition.tex

User Interface

• \printDef{csname}, print definition of \cs{csname}
• \printAndRunCode{code}

Internals

• direct dependencies:
  • fvextra
  • xcolor with no package options
• added
  • \toString

utilities/pgfkeys-handler-patch.tex

User Interface

• \pgfkeys{<key>/.patch={<search>}{<replace>}}
• \pgfkeyspatchvalue{<key path>}{<search>}{<replace>}

Internals

• direct dependency: xpatch

utilities/pgfkeys-handler-store-in.tex

User Interface

• after <key>/.store in=<macro> (or .estore in), handlers .get, .add, .prefix, and .append will act on <macro>, not the key itself

Internals

• <macro> is stored in new subkey .@store, which will be cleared by .initial
• for the above four handlers, .@store has higher precedence than the key itself (set by .initial)

utilities/hyperref-autonameref.tex

User Interface

• \autonameref{<label key>} and \autonameref*{<label key>}
• 1-arg \HyRef@autonameref@style which controls the extra output style (see test file)

Internals

• direct dependency: hyperref
• \HyRef@autonameref and \HyRef@autonamesetref

utilities/tikz-auto-mark-nodes.tex

User Interface

• scope options auto mark and no auto mark
• styles every auto mark and every auto <shape> mark that accept pin options
• zero-arg macro \tikzAutoMarkText that controls the mark text
  • In the definition of the above styles and macro, \tikzNodeName and \tikzNodeShape can be used as placeholders of node name and shape, respectively.

Initial values

```tex
\tikzset{
  every auto mark/.style={
    font=\ttfamily, rotate=45,
    red, anchor=west, pin position=45,
  },
  every auto coordinate mark/.style={
    blue, anchor=east, pin position=180+45,
  },
}
\newcommand\tikzAutoMarkText{\tikzNodeName}
```

Internals

• Every auto mark is a node pin drawn by

  \node also[pin={[every auto mark/.try, every auto <shape> mark/.try]{\tikzAutoMarkText}}] (\tikzNodeName);
  

  at the end of every tikzpicture.
  • maybe draw in execute at end path?
• direct dependency: tikz and etoolbox (for \patchcmd)
• tikz options used: execute at begin scope and execute at end picture
• patched: \tikz@node@finish to append node info to \tikzNodeList
• added:
  • \tikzNodeList, A comma-separated list of elements {<node_name>, <node_shape>}
  • \newif\iftikz@lib@automark@on
