cal skips first week on months with first day on sat
|
|
Yeah. Honestly, I'm not sure right now. But, then again, my
|
|
brain is currently fried in multiple ways, so, we'll check
|
|
again in the morning.

cal gets months on some years wrong
|
|
For instance, if you run `./cal 08 08`, the first day of the
|
|
month is off by one day. It's weird, and I don't know why it
|
|
happens.

wc needs multibyte support
|
|
It's supposed to have a flag, -m, that counts characters, as
|
|
opposed to -c which counts bytes (ASCII characters, if you
|
|
will). We need to add in support for -m proper, using some
|
|
form of multibyte.
|
|

|
|
|
cal needs the ability to show a whole year calendar
|
|
This needs to be done eventually.

sh probably needs to be trashed and restarted
|
|
When I started it, it was from a small online tutorial on the
|
|
basics of how shells work. It was more a demonstration of
|
|
things like forking and the execvp and waitpid functions. It
|
|
wasn't actually intended to grow into a proper shell. As it
|
|
stands this is just going to keep getting cobbled together
|
|
until it collapses under its own weight. It's probably better
|
|
to restart now, parse input using lex and yacc instead of
|
|
doing it ourselves, and work from there on implementation
|
|
of everything. We know the basics of how a shell does its
|
|
thing (fork, execvp, waitpid), now to use that with newer
|
|
knowledge of building language parsers with things like lex
|
|
and yacc, getting command line arguments with getopts, and
|
|
other things that will lead to a proper, fully-formed shell.

NOTES
|
|
*****
|
|
|
|
Some things may get added:
|
|
|
|
From the LSB:
|
|
chfn, chsh, dmesg, egrep, fgrep, groupadd, groupdel, groupmod,
|
|
groups, gunzip, gzip, hostname, install, killall, md5sum,
|
|
mknod, mktemp, mount, passwd, pidof, sendmail, seq, shutdown,
|
|
su, sync, tar, umount, useradd, userdel, usermod
|
|
|
|
In general:
|
|
a cobol compiler, a debugger, an assembler, look/spell, wall
|
|
|
|
And some need to get defined:
|
|
other
|
|
news/calendar - Both are referenced in the "Rationale" section of
|
|
The Open Group Base Specification Issue 7 as utilities that
|
|
weren't included. Both sound kinda interesting. I kinda want
|
|
to included them. Unfortunately, I have no clue what they are
|
|
or how they work. So, either I need to dig 'em up and find out,
|
|
or I need to define them myself.
|
|
*GOOD NEWS!* I found the heirloom utility set, which includes
|
|
both of these applications! Yay!
|
|
|
|
notes on things not in POSIX or other standards:
|
|
tac: it's basically cat but backwards
|
|
rev: Reverses a file line-by-line
|
|
|
|
So, POSIX-conformant applications are supposed to define the
|
|
_POSIX_C_SOURCE macro with value 200809L to enable POSIX features
|
|
and the macro _XOPEN_SOURCE with value 700 if they're XSI-compliant.
|
|
For any XSI-compliant utilities, we really should define the
|
|
_XOPEN_SOURCE macros; for any non-XSI-compliant applications, we
|
|
should really define the _POSIX_C_SOURCE macro until such a time
|
|
when/if they become XSI-compliant. |
