tpp - text presentation program
What is tpp?
tpp stands for text presentation program and is an ncurses-based presentation tool. The presentation can be written with your favorite editor in a simple description format and then shown on any text terminal that is supported by ncurses - ranging from an old VT100 to the Linux framebuffer to an xterm.
- Ruby 1.8 http://www.ruby-lang.org/
- a recent version of ncurses
- ncurses-ruby https://github.com/eclubb/ncurses-ruby
- FIGlet (if you want to have huge text printed)
Just get root and type
Start tpp with the presentation file you would like to display:
$ tpp presentation.tpp
To control tpp, the following keys are available:
space bar, cursor-down, cursor-right ... display next page b, cursor-up, cursor-left .............. display previous page q, Q ................................... quit tpp j, J ................................... jump directly to page l, L ................................... reload current file s, S ................................... jump to the start page e, E ................................... jump to the last page c, C ................................... start command line ?, h ................................... show help screen
On the lower left side of your terminal you will notice the current slide number and the total number of slides. Left of that, a ‘*’ will appear when the end of the current slide has been reached. If no ‘*’ appears, pressing space bar the next time will show the next entry on the page (separated by ‘—’). You are also able to go to the next/previous page at this point.
When you press ‘l’ (lower-case L) or ‘L’, the file you have currently loaded into tpp will be reloaded from disk. This is very useful when you write presentations with tpp, and constantly need a preview.
Writing tpp presentations
The tpp presentation formats consists of normal text lines and special commands. Special commands are contained in lines that begin with “–” and the command name.
The presentation is divided into 1 or more pages, which are separated by the “–newpage”. Before the first “–newpage” is encountered, all non-command text is used as the presentation’s abstract. Here, the title, the author and the date can be set, too. You can also optionally specify a name for a page: append it to the “–newpage” command, separated by a single blank. If no name is set, a name will be automatically generated.
The following commands are allowed in the abstract page:
–author: sets the author of the presentation
–title: sets the title of the presentation
–date: sets the date of the presentation. If the date is “today”, today’s date is inserted instead. You can set a custom format string if you append it after “today”, separated by a blank. Date formats are like formats for date(1), and documented in this manual page. If no format string is supplied, “%b %d %Y” is assumed as default.
–bgcolor <color>: the background color is set to <color>.
–fgcolor <color>: the foreground color is set to <color>.
Valid colors are white, yellow, red, green, blue, cyan, magenta, black and default for transparency.
Within a page, so-called “page-local” commands can be used. The following page-local commands are available:
–heading <heading>: draw a heading. Headings will be centered and drawn in bold (if supported by the terminal).
–horline: draws a horizontal line in the current line
–header: adds text to the first line on the screen
–footer: adds text to the last line on the screen
–color <color>: draw the text with specified color until a new color is set
–center <text>: center <text>. The text will be drawn centered.
–right <text>: draw <text> right-oriented. When drawing the text, it will be aligned on the right side of the terminal.
—: stop drawing until space bar has been pressed.
–beginoutput: marks the beginning of a framed output
–endoutput: marks the end of a framed output
–beginshelloutput: marks the beginning of a framed shell output. The difference between normal output and shell output is that lines that start with $,%, or # are printed as if they were typed by a person.
–endshelloutput: marks the end of a shell output
–sleep <seconds>: tpp stops for 3 seconds, doing nothing and accepting no input.
–boldon: switches on bold printing –boldoff: switches off bold printing
–revon: switches on reverse printing (i.e. reverse fg and bg colors) –revoff: switches off reverse printing
–ulon: switches on underlined printing –uloff: switches off underlined printing
–huge <text>: <text> is drawn in huge letters. FIGlet is used to generate the huge letters.
–sethugefont <font>: If you use –huge FIGlet will use the specified <font> to generate the huge letters. You will find the names of the available fonts in the figlet manual.
–exec <cmd>: executes <cmd>. Useful for e.g. starting image viewers.
–beginslideleft: starts the “slide in from left” mode –endslideleft: ends the “slide in from left” mode
–beginslideright: starts the “slide in from right” mode –endslideright: ends the “slide in from right” mode
–beginslidetop: starts the “slide in from the top” mode –endslidetop: ends the “slide in from the top” mode
–withborder: makes a border around the current page
–beginslidebottom: starts the “slide in from the bottom” mode –endslidebottom: ends the “slide in from the bottom” mode
$$ cmd : append the stdout of executing cmd in the shell $% cmd : append the stdout of executing cmd in the shell with % at the beginning of every line(useful with –beginshelloutput).
You can comment lines using –##
For a collection of examples that demonstrate the different features of tpp, please have a look into the examples subdirectory in the tpp source distribution.
tpp –help: displays help in text mode tpp -l output input.tpp: converts tpp file into a LaTeX slide tpp –version: displays version number
The LaTeX slide output option is currently unsupported and will most likely not work correctly!
Vim syntax file
To use the vim syntax file you have to copy the tpp.vim file into ~/.vim/syntax/. If the directory does not exist you have to create it. In the next step you have to copy the following into ~/.vim/filetype.vim:
if exists("did_load_filetypes") finish endif augroup filetype detect au! BufRead,BufNewFile *.tpp setfiletype tpp augroup END
If your vim editor does not use syntax highlighting in the default setup you have to change to the vim command mode and type: syntax on.
Beside the tpp.vim in the contrib subdirectory, there’s also another, more sophisticated version, which we unfortunately cannot distribute due to license reason. You can find this file at http://www.trish.de/downloads/tpp.vim
OSX TextWrangler/BBEdit syntax file
To use the TextWrangler syntax file you have to copy the TPP.plist file into ~/Library/Application Support/TextWrangler/Language Modules/.
