The beginner user should find the instructions in the form of a slide presentation @hyperlink["http://andreimikhailov.com/slides/bystroTeX/slides-manual/index.html"]{here}, and also study the sample file @tt{slides-manual.scrbl}, which is in the samples directory. That sample file can be used as a template for creating new presentations. As a general rule, those functions whose name starts with @tt{bystro-}, are either for internal use or for use in the header. They are not meant to be used in slides by themselves, or at least not to be used frequently. (But this rule is not very strict.) @section{Functions for manipulating slides} @defmodule[(planet amkhlv/bystroTeX/slides)] @defstruct[bystro ([formula-processor path?] [formula-database-name string?] [formula-dir-name string?] [formula-size integer?] [formula-bg-color (listof integer?)] [formula-fg-color (listof integer?)] [autoalign-adjust integer?] [manual-base-alignment integer?])]{ Configuration structure (mutable)} @defproc[ (bystro-titlepage-init) element? ]{ Installs the titlepage style } @defproc[ (slide [x content?] [#:tag tg (or/c symbol? string? #f) #f] [#:showtitle sttl boolean? #f] [#:rest xs (listof pre-flow?)] ) part? ]{ A basic slide. The title of the slide is @racket[x], and the contents are @racket[xs]. I recommend providing a nice tag @racket[tg], which will serve as a filename for the html.

Notice the absence of quotation marks around @tt{attn} in the first argument of @tt|-{@span}-|. The corresponding CSS could be, for example: @verbatim|{ .attn { color: red; font-weight: bold; } }| (that's how it is currently defined in @tt{misc.css}) } @defform[(div someword content)]{ Similar to @racket[spn] but creates @tt{div} instead of @tt{span}: @tt{
content
} The difference is that @tt{div} can extend over several paragraphs. } @defform[(tg someword content)]{ Creates @tt{content}, for example: @verbatim|--{ @tg[ol]{ @tg[li]{The union of open sets is an open set.} @tg[li]{The finite intersection of open sets is an open set.} @tg[li]{@f{X} and the empty set @f{\emptyset} are open sets.} } }--| } @defform[(init-counter name)]{ This is to set up a counter. For example, suppose that I want to include exercises in my slides. The exercises should be numbered, Exercise 1, Exercise 2, @italic{etc.} In the header, I add: @verbatim|--{ @(require racket/dict) @(init-counter exercise) @(define (ex-num label) (elemtag label (number->string (exercise-next label)))) @(define (ex-ref label) (elemref label (string-append "Exercise " (number->string (exercise-number label))))) }--| Then, when I want to give the next Exercise, I say: @verbatim|--{ @bold{Exercise @ex-num{ProvePositivityOfE}:} Show that the energy is always greater thatn zero }--| When I need to refer to this exercise later, I say: @verbatim|--{ As you should have proven in @ex-ref{ProvePositivityOfE}, ... }--| } @defproc[ (tbl [rows bystro-rectangular-table?] [#:orient dirn (or/c 'hor 'vert #f)]) table? ]{ To insert a table } @defform[(align alignment-scheme content ...)]{ This is a table-like structure, useful for multiline formulas.

A better version: @verbatim|--{ @align[r.l @list[ @f{{2\over 1 - x^2} = } @v+[2 @f{1+x+x^2 + \ldots +}] ]@list[ "" @f{1-x+x^2- \ldots} ] ] }--| Notice that in the first line stands the symbol @racket{r.l} which defines the alignment (right, then left). The @racket{v+} is a padding, it serves for vertical adjustment, see below. The @bold{numbered} version of the same formula will be @verbatim|--{ @align[r.l.n @list[ @f{{2\over 1 - x^2} = } @v+[2 @f{1+x+x^2 + \ldots +}] "" ]@list[ "" @f{1-x+x^2- \ldots} @label{SumOfGeometricProgressions} ] ] }--| Notice that the alignment symbol is now @racket[r.l.n], we added letter @racket[n] for the number.
