1) Update manpage with the num-syntax.
2) Use size_t for years and derivatives.
3) Use putchar instead of printf wherever possible.
4) Update usage().
5) Style changes.
1) Refactor manpage.
2) De-globalize local values.
3) update usage().
4) sort local variable declarations.
5) fix wrong argument in strtonum (3 -> 1).
6) argc-argv style, boolean style.
7) check bytes > 0 before accessing b.lines[i][bytes - 1]
relying on len only makes sense but let's not push it.
7) don't break on maxlen > (chars - 1) / 2. This didn't even
make sense.
8) _correctly_ calculate cols and rows in a readable way.
9) Rewrite loop over rows and cols in a readable way and
using putchar in a loop instead of printf-magic or fputs
where not necessary.
- Also fix a few typos, style and section order.
- Changed the text "800 characters per line" to "800 bytes per line" as col
doesn't seem to support UTF-8 right now.
1) don't mix declarations and code (leave recursion alone for now as I
plan on changing/using recurse)
2) change **argv to *argv[]
3) check for error on fork()
We'll probably develop this outside of sbase. A simple script that
parses /etc/magic and generates magic.h would be sufficient.
The table can be huge and we do not want to bloat up binary size
only for file(1).
1) Clarify behaviour when the f-flag is given and a target is in its
own way.
2) Fix usage()-style.
3) Group local variable declarations.
4) reorder args
5) argc style, other boolean style changes
6) improve error messages
7) set argv[argc - 1] to NULL to allow argv-centric loop later
8) BUGFIX: POSIX specifies that when with the f-flag there's a
situation where a file stands in its own way for linking it
should be ignored.
9) Add weprintf() where possible, so we don't pussy out when there's
a small issue. This is sbase ffs!
1) Update manpage, refactor the HLP-section and other wordings.
2) BUGFIX: If chmod() fails, don't recurse.
3) Rewrite the arg-loop, fixing several issues:
BUGFIX: Handle multi-flags (e.g. -RH)
BUGFIX: Properly handle the termination flag --, error on e.g. --x
BUGFIX: Error out on an empty flag -.
4) Refactor logic after the arg-loop, which is now simpler thanks
to argv-incremention.
1) No need for strchr() in mkdirp or a while-loop. Rewrite it in
a sane and readable way.
2) fix usage according to the manpage.
3) order includes, don't align local variables.
4) argc-style-fix.
5) BUGFIX: Don't try to chmod() *argv when mkdir() / mkdirp() failed.
6) Add newline before return in two places.
1) use arg.h
2) !strcmp
3) **argv to *argv[]
4) fix test to check if basename(argv0) == "[" but avoid
basename(3p) as it may change the contents of the string
passed to it and I didn't want to make a copy.
1) Use (s)size_t in head().
2) BUGFIX: only check buf[len - 1] when len > 0, else there would
be an overflow when getline returns 0 (which can happen) and a
very potential segmentation fault.
3) fix error-messages.
4) update usage().
5) argv-argc-style.
6) clear up the main loop with if (newline).
7) add newline before return.
1) fix usage().
2) sort includes and comment properly. rename rbeg and rend to r0 and r1.
3) argc style and usage fixes.
4) make error-messages clearer.
5) BUGFIX: It was ignored when fork() failed.
6) Don't call enprintf() after execvp and use _exit instead.
1) Make argument-naming consistent with other tools (cp(1), ...)
2) style fixes
3) usage() fix
4) BUGFIX: Probably from the old non-arg.h days, the directory-
check was only done when argc > 3, but with arg.h, this ignores
the case when 3 arguments were given.
This is actually a pretty serious issue and I'm glad it's fixed.
5) Moreover, be more verbose when stat() fails and make it clearer
what the hell is going on at this checkpoint.
1) "duplicate" implies that you can only specify two outputs,
"multiply" is a better word describing the functionality.
2) fix other wording in the manpage
3) fix usage()
4) reorder local variables
5) fix sizeof() style
6) we need argv later, don't increment argv and rather iterate
over argc.
7) Improve error messages, print the filename which the write
failed to instead of printing the buffer itself (how much
sense does that make, printing 1024 Bytes of garbage?).
Also, give the name of the function which failed.
1) no need to include sys/stat.h
2) remove the enum which just added a layer too thick on this simple
program
3) argc-style, other style
4) weprintf instead of enprintf, then save the error-message of
execvp before and return the proper status.
5) write consistent "not reached" comment.
col is used to display troff documents in ttys, removing the reverse
line feeds generated by .2C in ms. This implementation keeps the limit
of 256 lines of 800 characteres of the original implementation.
The HLP-changes to sbase have been a great addition of functionality,
but they kind of "polluted" the enmasse() and recurse() prototypes.
As this will come in handy in the future, knowing at which "depth"
you are inside a recursing function is an important functionality.
Instead of having a special HLP-flag passed to enmasse, each sub-
function needs to provide it on its own and can calculate results
based on the current depth (for instance, 'H' implies 'P' at
depth > 0).
A special case is recurse(), because it actually depends on the
follow-type. A new flag "recurse_follow" brings consistency into
what used to be spread across different naming conventions (fflag,
HLP_flag, ...).
This also fixes numerous bugs with the behaviour of HLP in the
tools using it.
1) Refactor the manpage, which has been a bloody mess, documenting
fantasy-flags (-d for example) and add a STANDARDS section
2) fix usage()
3) sort ARG-block
4) Check return-value of stat() separately, so a lack of permissions
doesn't tell the user "the directory doesn't exist", which could
be a bit confusing.
5) Add empty line before return.
1) Fix usage()
2) Group local variables
3) Idiomatic argv-loop
4) BUGFIX: When the m-flag is specified, POSIX clearly says:
"Set the file permission bits of the newly-created FIFO to the specified mode
value."
This means, that if mkfifo() fails for some reason, it should not try to
chmod() the given path (which has been fixed with the "else if")
A simple testcase is:
$ touch testfile; mkfifo -m 000 testfile;
GNU mkfifo(1): ls -l testfile
-rw-r--r-- 1 testfile
sbase mkfifo(1): ls -l testfile
---------- 1 testfile
5) Add blank line before return
1) val is sufficient as "int" (read the standard)
2) BUGFIX: If getpriority fails, it returns -1 and sets errno.
Previously, it would correctly catch the errno but not take
care of the fact that by then val has been decremented by 1.
Only change val if the getpriority-call has been successful.
3) Add LIMIT()-macro from st to increase readability.
4) setpriority returns < 0 on failure
5) Remove bikeshedding-comment. Read the standard if you wonder.
6) return-value trick from env(1)
