Class that allows to drop comments and figures into a presentation while interactively working with python

wn.save()

Existing items can be removed via Worknote.remove(index), where index is a tuple describing the item position. An overview over item positions can be obtained via print wn. The position of two items can be switched via Worknote.move(source, destination) where source and destination are the item indexes. An item can be inserted at a specific position by passing the index to the worknote call. Indices can be written either as a tuple, e.g. [0,0] is the first element on the first slide, or as a colon-separated text string, e.g. '0:0'. You can use any of the two possible notations for any index that you pass, e.g. wn.move([0,0], '1:0') is perfectly valid.

wn.build() Creates by default a LaTeX Beamer pdf. The following styles are available and can be passed as argument:

• 'Beamer' - Build Beamer.tex and generate Beamer.pdf (default)
• 'Beamer.tex' - Builds Beamer.tex
• 'Report' - Builds Report.pdf
• 'Report.tex' - Builds Report.tex
• 'Markdown' - Builds Report.md

Item can be added via wn(item, cat=category), where wn is a Worknote object, the item is the object to pass to the worknote and the category is a descriptive string. If no category is given, the Worknote tries to determine the category from implicit declarations of the item object. E.g. wn(" * Listitem") is equivalent to wn('Listitem', cat='list').

The following categories are available:

• slide - A slide or section of the worknote, implicit via "Your Title \n---"
• text - A text string, no implicit declaration necessary
• equation - An equation, implicit via "$$ your equation $$"
• list - An item of a list, implicit via " * Your item"
• enumerate - An item of an enumerated list, implicit declaration via " # Your item"
• figure - A figure, implicit via passing a matplotlib figure, or passing the filename of a figure with ending .pdf, .png, .jpg, .jpeg.
  • Argument: size - Size in textwidth, default = 1
  • Argument: align - Alignment of figure, ('left', 'right', 'center', None), default = 'center'. If None is given as argument, no align environment ist specified and the figure will appear in line with other objects
  • Argument: gfxfmt - output format for matplotlib figures, default = 'pdf'
• figurepage - Same as 'figure', but forces figure on a new slide
• table - A table, implicit via passing a list or a numpy array. Table object need to be a 2D list or array. If the first line contains a string, Ite is assumed to be the table description.
  • size - Can be an arbirary LaTeX fontsize (only relevant for LaTeX right now). default='normalsize'. If set to 'auto', size is determined by table length. This assumes an empty slide ...
• value - A numeric value. Must be an instance of either int, numpy.int64, float or numpy.float64. Additional options are:
  • desc - A description of the variable. Gets printed in front of the value, followed by a colon.
  • units - The units of the variable. Gets printed behind the value.
  • precision - The precision of the floating point output (ignored for integer variables). If the value is too small to be represented in the chosen precision, the value is automatically printed in scientific notation.
  • error - An error for the value. Gets printed using the same precision and formatting as the value itself.
