.SH NAME
spit \- simple presentation tool
.SH SYNOPSIS
.B spit
[
.I -n
]
.I file
.SH DESCRIPTION
.I Spit
reads the presentation described in
.I file
and renders it in a graphical window. The format of the presentation is described below in
.IR "Presentation format"
.
With the presentation displayed, navigation between slides is achieved using the 
.B left and 
.B right arrows (or 
.B backspace and 
.B space
respectively), it is also possible to go back to the first slide of the presentation using the 
.B home
key and to the last one using the
.B end
key. Pressing the
.B f
key will toggle fullscreen mode making the window fill the entirety of the screen, or restore the window to its original size.
.I Spit
is exited with either
.B q
or the
.B delete
keys.
.PP
If the
.I -n
flag is passed, the presentation will not be displayed but instead each slide will be rendered to an image named 
.I spit.NNN.bit
(with NNN being the slide number) in the current directory.
.SS Presentation format
Presentations are plaintext files written in a markdown-like format. A new slide is started with a line starting with a
.I pound
character (#) followed by a space then the title of the slide. Within a slide, 
.I spit
recognizes the following directives
.TP
.B Lists
A list starts when
.I spit
encounters a line starting with a 
.I dash
 followed by a space and until a line does not.
.TP
.B Quotes
A quote starts when
.I spit
encounters a line starting with a 
.I greater than
sign followed by a space and can span multiple lines.
.TP
.B Code
A code listing can be inserted by putting three backticks on a single line. All following lines will then be rendered as code and this until a line with three backticks is encountered again.
.TP
.B Images
An image, in p9 format, can be inserted by putting an
.I exclamation mark
followed by a space and the path to the file.
.PP
Lines starting with a semi-colon are comments and ignored by
.I spit .
All other lines are rendered as bullet points in the slide.
.PP
The presentation style can be configured with a style directive (see
.IR "Style configuration"
). These directives must come first in the presentation (comments notwithstanding).
.SS Style configuration

has a predefined style for all presentation elements but this can be changed using style directives. A style directive is defined using the

keyword with the following syntax:

@style[element] = value
