kbauer / Meaning
Created July 15, 2015 15:52
For debugging/learning LaTeX internals it is useful to dump the definition of commands. Reading the output of `\show` from the console however is inconvenient. The command `\meaning` is useful here (as it prints the definition to the document) but limited. `\mymeaning` is a wrapper, where you specifiy the name of a macro rather than the `\macro`…
% \mymeaning{command} -> Definition of \command
\makeatletter
\newcommand{\mymeaning}[1]{

A tool for converting scanned or photographed pages into a fax-style bi-level png with minimal storage use. Also removes background color gradients. See also my other gist `imagemagick-scan-pdf-to-mono.sh`

A companion script for the BoogieBoard Sync 9.7 eWriter. The main purpose is to put the latest Bluetooth-synced page into the clipboard as image data. Depends on the `imagemagick-scan-to-mono.sh` script (see https://gist.github.com/kbauer/e5bd0dc12142e7a6c97f).

kbauer / ONEARG.h
Last active February 19, 2016 15:42
A C preprocessor macro that allows executing code depending on the number of arguments in `__VA_ARGS__`. Test with `gcc -std=c99 -E`. Original version of an `_IFEMPTY` macro was discarded because it depended on the GCC extension syntax `## __VA_ARGS__`.
/// Usage: _ISONEARG() -> 1
/// _ISONEARG(A) -> 1
/// _ISONEARG(A,B,...) -> 0
///
/// Alternative to _IFEMPTY, that works with standard C.
/// Works for up to 100 arguments.
///
/// Examples:
///
/// "_ISONEARG()" -> 1

kbauer / FORVARARGS.h
Last active February 19, 2016 15:40
A c preprocessor macro allowing to iterate over an argument list `A1, A2, ...` to produce `M(1, A1), M(2, A2), ...` or the reverse. Depends on ONEARG.h, see https://gist.github.com/kbauer/d651bae52ab2f72b8d1e . Tested with `gcc -E -std=c99`.
// Usage: _FORVARARGS(M,A0[,A1[,A2[...]]])
//
// Equivalent to M(0,A0) M(1,A1) M(2,A2) ...
// Supports up to 32 Varargs. Emacs lisp code for generating included.
// Define the macro M(N, ARG) to generate useful code.
//
// Usage: _FORVARARGS_R(M,A0[,A1[,A2[...]]])
//
// Equivalent to ... M(2,A2) M(1,A1) M(0,A0), i.e. reverse of _FORVARARGS.
