If we read in a line with \0 at the beginning, blen will be 0. However, we then try to index our copy of the buffer with s->lines[s->linecount][blen-1], we'll read (and potentially write if the data happens to be 0x0A) outside of strdup's allocated memory, and may crash. Fix this by just rejecting lines with a leading \0. Lines with nulls embedded in other places don't invoke similar behaviour, since the length is still >0. |

sent is a simple plaintext presentation tool.
sent does not need latex, libreoffice or any other fancy file format, it uses plaintext files to describe the slides and can include images via farbfeld. Every paragraph represents a slide in the presentation.
The presentation is displayed in a simple X11 window. The content of each slide is automatically scaled to fit the window and centered so you also don't have to worry about alignment. Instead you can really concentrate on the content.
Dependencies
You need Xlib and Xft to build sent and the farbfeld[0] tools installed to use images in your presentations.
Demo
To get a little demo, just type
make && ./sent example
You can navigate with the arrow keys and quit with q.
Usage
sent [FILE]
If FILE is omitted or equals -, stdin will be read. Produce image slides by
prepending a @ in front of the filename as a single paragraph. Lines starting
with # will be ignored. A \ at the beginning of the line escapes @ and
#. A presentation file could look like this:
