John’s PHP Extension library

Posted on by

Note to self: my PHP extension is here: jj5@tact:/home/jj5/repo/git/git.php.net/php-src/ext/pext

The .so file (shared object) is in modules/pext.so

I linked it in like this:

-------------------
Sun May 23 13:44:22
root@tact:/usr/lib/php/20170718
# ln -s /home/jj5/repo/git/git.php.net/php-src/ext/pext/modules/pext.so .
-------------------

Configured it like this:

-------------------
Sun May 23 13:44:47
root@tact:/usr/lib/php/20170718
# cat /etc/php/7.2/cli/conf.d/pext.ini

extension=pext.so

-------------------

And I can build it like this:

-------------------
Sun May 23 13:51:37
jj5@tact:/home/jj5/repo/git/git.php.net/php-src/ext/pext
$ make clean && make

Knuth on reusable code

Posted on by

Today via Lobsters: APL Style: Patterns/Anti-patterns:

I also must confess to a strong bias against the fashion for
reusable code. To me, “re-editable code” is much, much better
than an untouchable black box or toolkit. I could go on and on
about this. If you’re totally convinced that reusable code is
wonderful, I probably won’t be able to sway you anyway, but
you’ll never convince me that reusable code isn’t mostly a
menace.
