Linux Tools: ddate and cat/proc/*

Two new APIs are added: they are ddate and cat-proc.

cat-proc

cat-proc is actually not a linux commnad. It is short for cat /proc/* where * is the filename under folder /proc。 There are many information-related files you can output the contents. For example, uptime, cpuinfo, meminfo, filesystems etc. So you can output the file using API cat-proc with parameter file.

For example, https://helloacm.com/api/cat-proc/?file=cpuinfo

returns JSON-format string:

ddate

ddate is a fun date conversion tool from Gregorian dates to Discordian date. If no parameters given, it will assume today as current date. It can then have four parameters, +format, day, month, and year.

For example, https://helloacm.com/api/ddate/?d=1&m=1&y=2011

gives:

"Sweetmorn, Chaos 1, 3177 YOLD\n"
