* 2277 - reagents now have a tree of typesKartik K. Agaram2015-10-251-1/+1

* 2258 - separate warnings from errorsKartik K. Agaram2015-10-061-10/+10
| | | | | | | At the lowest level I'm reluctantly starting to see the need for errors that stop the program in its tracks. Only way to avoid memory corruption and security issues. But beyond that core I still want to be as lenient as possible at higher levels of abstraction.
* 2226 - standardize warning formatKartik K. Agaram2015-10-011-2/+2
| | | | | | | | Always show recipe name where error occurred. But don't show internal 'interactive' name for sandboxes, that's just confusing. What started out as warnings are now ossifying into errors that halt all execution. Is this how things went with C and Unix as well?
* 2199 - stop printing numbers in scientific notationKartik K. Agaram2015-09-141-3/+3
| | | | | | | | | | | Turns out the default format for printing floating point numbers is neither 'scientific' nor 'fixed' even though those are the only two options offered. Reading the C++ standard I found out that the default (modulo locale changes) is basically the same as the printf "%g" format. And "%g" is basically the shorter of: a) %f with trailing zeros trimmed b) %e So we'll just do %f and trim trailing zeros.

| | | | | | | | | | | | Finally terminate the experiment of keeping debug prints around. I'm also going to give up on maintaining counts. What we really need is two kinds of tracing: a) For tests, just the domain-specific facts, organized by labels. b) For debugging, just transient dumps to stdout. b) only works if stdout is clean by default. Hmm, I think this means 'stash' should be the transient kind of trace.
* 2075Kartik K. Agaram2015-08-241-0/+16
| | | | Thanks Caleb Couch for bugfixes 2072-2075.
* 2043Kartik K. Agaram2015-08-201-1/+1
| | | | | Traces were changing based on whether I was loading a .mu file with 'main' or not.
* 1962Kartik K. Agaram2015-08-091-2/+2
| | | | Standardize test names.
* 1868 - start using naked literals everywhereKartik K. Agaram2015-07-281-38/+38
| | | | First step to reducing typing burden. Next step: inferring types.
* 1847Kartik K. Agaram2015-07-251-2/+2

* 1844 - explicitly end each trace lineKartik K. Agaram2015-07-251-11/+11
| | | | | | | | | More verbose, but it saves trouble when debugging; there's never something you thought should be traced but just never came out the other end. Also got rid of fatal errors entirely. Everything's a warning now, and code after a warning isn't guaranteed to run.
* 1837Kartik K. Agaram2015-07-241-4/+4
| | | | | | Don't die on unbalanced '{'. I won't bother adding more tests for warnings. Suffice it to say that we need to gradually eliminate all asserts that check for illegal mu code.
* 1763 - warn on break/loop outside {}Kartik K. Agaram2015-07-111-85/+54
|
* 1702 - experiment: start using 'ordinal' in namesKartik K. Agaram2015-07-041-25/+25
| | | | | | | It comes up pretty early in the codebase, but hopefully won't come up in the mu level until we get to higher-order recipes. Potentially intimidating name, but such prime real estate with no confusing overloadings in other projects!

* 1390 - support non-integer literalsKartik K. Agaram2015-05-171-8/+12
| | | | | | | | | | | | | | | | | | | | Since '3.14159:literal' looks ugly, we'll just say '3.14159'. It's not like non-integers can be confused for anything but literals. Once I tried to turn reagent values into doubles, I uncovered a bug: arithmetic using signed integers is busted; if either operand of subtraction is unsigned the result is unsigned as well. If it needs to be negative: ka-boom. It was only masked because I was eventually storing the result in a long long int, where it was out of range, and so overflowing into the correct signed value. Once I switched to doubles the unsigned value would indeed fit without overflowing. Ka-boom. Yet another reminder that unsigned integers suck. I started using them mostly to avoid warnings in loops when comparing with .size(), which is usually a size_t. Who knows what other crap lurks here. Just use signed integers everywhere. (And avoid bitwise operators.)
* 1363 - rename 'integer' to 'number'Kartik K. Agaram2015-05-131-44/+44
| | | | ..now that we support non-integers.
* 1362Kartik K. Agaram2015-05-131-1/+1
| | | | | | | | Mu allows us to use multiple ingredients/products without commas, but make sure we don't. $ grep "<- [^ ]\+ [^#\[,]* [^#\[,]*$" * $ grep "^[ ]*[^ #,][^#,]* [^#,]* <- " *
* 1357 - temporarily revert floating-point supportKartik K. Agaram2015-05-121-16/+15

* 1356 - snapshot #2: floating point supportKartik K. Agaram2015-05-121-15/+16
| | | | | | | | | | | | | | | I added one test to check that divide can return a float, then hacked at the rippling failures across the entire entire codebase until all tests pass. Now I need to look at the changes I made and see if there's a system to them, identify other places that I missed, and figure out the best way to cover all cases. I also need to show real rather than encoded values in the traces, but I can't use value() inside reagent methods because of the name clash with the member variable. So let's take a snapshot before we attempt any refactoring. This was non-trivial to get right. Even if I convince myself that I've gotten it right, I might back this all out if I can't easily *persuade others* that I've gotten it right.
* 1323 - keyboard supports backspace and newlineKartik K. Agaram2015-05-101-0/+1
| | | | | | Lots mixed into this commit: some off-by-one errors in display.cc a new transform to translate jump labels that I'd somehow never gotten around to supporting
* 1299 - stop using [] in any vectorKartik K. Agaram2015-05-071-3/+3
| | | | | | | | | Useful check: $ grep "[^ '\"]\[[^\"]" *.cc \ |perl -pwe 's/\Wargv\[|\WTests\[|\Wframe\[|\WMemory\[|\WName\[|\WSurrounding_space\[|\WRecipe\[|\WType\[|\WRecipe_number\[|\WType_number\[|\WBefore_fragments\[|\WAfter_fragments\[//g' \ |perl -pwe 's/\Wargv\[|\WTests\[|\Wframe\[|\WMemory\[|\WName\[|\WSurrounding_space\[|\WRecipe\[|\WType\[|\WRecipe_number\[|\WType_number\[|\WBefore_fragments\[|\WAfter_fragments\[//g' \ |grep '[^ ]\['
* 1298 - better ingredient/product handlingKartik K. Agaram2015-05-071-17/+24
| | | | | | | | | | | | | | | | | | | All primitives now always write to all their products. If a product is not used that's fine, but if an instruction seems to expect too many products mu will complain. In the process, many primitives can operate on more than two ingredients where it seems intuitive. You can add or divide more than two numbers together, copy or negate multiple corresponding locations, etc. There's one remaining bit of ugliness. Some instructions like get/get-address, index/index-address, wait-for-location, these can unnecessarily load values from memory when they don't need to. Useful vim commands: %s/ingredients\[\([^\]]*\)\]/ingredients.at(\1)/gc %s/products\[\([^\]]*\)\]/products.at(\1)/gc .,$s/\[\(.\)]/.at(\1)/gc
* 1276 - make C++ version the defaultKartik K. Agaram2015-05-051-0/+384
I've tried to update the Readme, but there are at least a couple of issues.
