Some fragments of programs. Some of these I use as a sort of template to modify, which I keep around to remind me how I did something.
comment.c |
An example of identifying partial lines with
fgets(). |
xstrrep.c |
In response to the stock reply it takes five minutes to write your own. It took me the best part of a day. |
substr.c |
Substrings using either absolute offsets, or a start and a length. Negative ranges are permitted. |
trim.c |
trimming whitespace. |
lcm.c |
The LCM and GCD of two numbers. |
log.c |
Things related to logarithms. These are the sorts of things I am bad at getting right. |
bits.c |
Dealing with bits, which I am also bad at getting right. |
temp.sql |
Support routines for creating temporary tables in PL/pgSQL, with their OID being cached. |
sprintf.sql |
A minimal sprintf() for PL/pgSQL. |
xmalloc.c |
xmalloc() and friends. |
dburi.c |
Database URI parsing for libdbi, written in C99. This provides a URI scheme similar to Trac's Database Connection Strings. Its unit tests are separate. |
regrep.c |
Substitute arrays of regmatch_t matches into
a formatting string. |
signal.c |
Fork a child and catch signals sent from the child to its parent. |
tok.c |
Various forms of push-driven tokenisation. |
csv.c |
CSV parsing as per RFC 4180. Here's the FSM as a diagram. Some states are duplicated in the code for ease of output; the grammar is equivalent. |
css.js |
Javascript DOM manipulation for CSS classes in XHTML. |
events.js |
Javascript DOM event manipulation. |
urlalloc.c |
A particularly brutal implementation of URL parsing. |
unescape.c |
Resolving C-style escape sequences for strings. |
args.c |
Argument parsing to produce argv[].
I found this difficult to do neatly. |
And some fragments of things:
| Bit Twiddling | My collection of little bit-related things, which I can never figure out very easily on the spot. |
