The location of the link is in the About menu under the 'Contacting the IOCCC' and above 'Thanks for the help'. At first I had it at the very bottom, under 'IOCCC markdown guidelines', but it seemed better to have it closer to contacting the IOCCC. This is the same location in the no JavaScript menu (which, for those who do not know or forget, is not a requirement except for some screen sizes). The top level Makefile has a new 'security' rule. Updated make help. Typo fixes in make help. SECURITY.html has had a few updates as well: change the wording of entry code is unsupported (it now says 'ALL CODE IN ALL IOCCC ENTRIES IS UNSUPPORTED!!') and it now links to the mkiocccentry repo and how to report a possible security vulnerability in that repo; as that IS supported - and since there was reference to discussing security concerns is in SECURITY.html - even though the entries will not receive security updates - it seemed a good idea to have a link to report such security issues in the mkiocccentry repo. Perhaps the FAQ needs to be updated for this too.
To build:
make
To use:
./prog [arg ..]
Try:
./try.sh
Judges' remarks:
Think of this as a Maker Faire's make. :-)
It works reasonably well. While not super ultra-featured, it does fair well with the Makefile we supplied. Not only that, it helped uncover a bug we had in our special Makefile rules.
Author's remarks:
Remarks
This program is a tiny make(1) clone.
It is able to parse a subset of the make(1) syntax and will execute rules for
goals given in arguments if they need to (based on timestamp of dependencies
of rule targets).
Supported features
- Variable assignments (only recursive ones). Variable references with recursion.
- Environment variables are available.
- It is possible to specify variables in command line:
name=value. - Variables given in command line will have precedence over variables defined in Makefile, which will have precedence over environment variables.
- If no target given in command line, the first target defined will be used.
- Comments, escaped comments, escaped new lines.
It should be able to build programs of previous years with the provided Makefile
found in previous contest archives. Simply use this program instead of make.
It will recursively use itself for sub-make.
Limitations / Known issues
- There are a lot of memory leaks (not a single free).
- The opened file is not closed.
- The input file shall be named
Makefile. - No diagnostic message, but the exit status is non zero to indicates failure (failed command in a rule or missing target).
- Only
$<and$@are supported for automatic variables in commands. - No parallel execution (
-joption). - No
:=+=?=syntax for variable assignment. - No built-in function available.
- No pattern targets.
- No pattern substitution variables.
- No built-in rules.
- No built-in variables (except the one from environment).
- No conditional directives.
