Split into multiple files For multiple reasons the program is now split: - Make future porting to OpenBSD easier - Assign header includes to individiual functions - Make future program extensions easier - Recompile only changed parts 2017-09-17 16:18:17 +02:00

Add warn() and die() Given slstatus is a tool that runs in the background, most likely run from .xinitrc, it's important to prepend the name of the tool to error messages so it becomes clear where the error is coming from. To make this much more consistent, this commit adds warn() and die() utility functions consistent with other suckless projects and adapts all calls to fprintf(stderr, *) to the warn() and die() functions, greatly increasing the readability of the code. 2018-05-18 10:59:05 +02:00			`extern char *argv0;`

Implement esnprintf() and make formatted calls more efficient Within the components, snprintf() was unchecked and had inefficient calls in some places. We implement esnprintf() that does all the dirty laundry for us and use it exclusively now. 2018-05-19 19:33:04 +02:00			`int esnprintf(char str, size_t size, const char fmt, ...);`
