Fix coding style It was about damn time. Consistency is very important in such a big codebase. 2014-11-13 17:29:30 +00:00

Revert "Do not use arg.h for tools which take no flags" This reverts commit 9016d288f1cd03bf514fe84d537b203040e1ccf8. Tools that have no options are required by POSIX to support "--" so that conforming applications have a way to shield their operands from implementations that provide options as an extension. echo(1) is just an exception, so it is handled specially.

yes: Simplify, only support one argument The previous code was too difficult to decipher for such a simple tool. Since yes(1) is not specified in any standard and several well-known implementations only support a single argument, do the same here. Thanks to everyone who offered implementation suggestions in the hackers@suckless.org email thread. 2019-11-01 01:07:58 +00:00			`eprintf("usage: %s [string]\n", argv0);`
