* 2735 - define recipes using 'def'Kartik K. Agaram2016-03-081-16/+16
| | | | | | | | | | | | I'm dropping all mention of 'recipe' terminology from the Readme. That way I hope to avoid further bike-shedding discussions while I very slowly decide on the right terminology with my students. I could be smarter in my error messages and use 'recipe' when code uses it and 'function' otherwise. But what about other words like ingredient? It would all add complexity that I'm not yet sure is worthwhile. But I do want separate experiences for veteran programmers reading about Mu on github and for people learning programming using Mu.
* 2717 - bugfix for dilated reagentsKartik K. Agaram2016-02-261-0/+4
| | | | Make sure static arrays can take compound types.

|
* 2709Kartik K. Agaram2016-02-251-1/+0
| | | | | Only Hide_errors when strictly necessary. In other places let test failures directly show the unexpected error.

* 2681 - drop reagent types from reagent propertiesKartik K. Agaram2016-02-211-11/+11
| | | | | | | | | | | | | | | | | All my attempts at staging this change failed with this humongous commit that took all day and involved debugging three monstrous bugs. Two of the bugs had to do with forgetting to check the type name in the implementation of shape-shifting recipes. Bug #2 in particular would cause core tests in layer 59 to fail -- only when I loaded up edit/! It got me to just hack directly on mu.cc until I figured out the cause (snapshot saved in mu.cc.modified). The problem turned out to be that I accidentally saved a type ingredient in the Type table during specialization. Now I know that that can be very bad. I've checked the traces for any stray type numbers (rather than names). I also found what might be a bug from last November (labeled TODO), but we'll verify after this commit.
* 2677Kartik K. Agaram2016-02-201-2/+2
| | | | Include type names in the type tree. Though we aren't using them yet.
* 2671 - never use debug_string() in tracesKartik K. Agaram2016-02-191-2/+2
| | | | It's only for transient debugging.
* 2685Kartik K. Agaram2016-02-191-9/+9
| | | | | | | | | | | | | | | | Stack of plans for cleaning up replace_type_ingredients() and a couple of other things, from main problem to subproblems: include type names in the type_tree rather than in the separate properties vector make type_tree and string_tree real cons cells, with separate leaf nodes redo the vocabulary for dumping various objects: do we really need to_string and debug_string? can we have a version with *all* information? can we have to_string not call debug_string? This commit nibbles at the edges of the final task, switching from member method syntax to global function like almost everything else. I'm mostly using methods just for STL in this project.
* 2667 - redo container data structureKartik K. Agaram2016-02-171-8/+11
| | | | I've been gradually Greenspunning reagents. Just go all the way.
* 2660 - check dynamic arrays in exclusive containersKartik K. Agaram2016-02-151-11/+8
| | | | | Also a bugfix: don't cause future parse errors when these checks are triggered.
* 2658 - warn when containers contain arraysKartik K. Agaram2016-02-151-0/+32
| | | | | | | The rule is: a container type's size must be fixed. Arrays can violate this rule if the array length isn't included in the type. But we haven't been warning about this, and 'new' has been silently turning array elements to be empty.
* 2581 - make space for the refcount in address:sharedKartik K. Agaram2016-01-201-1/+2
| | | | | | | | | | | We don't yet actually maintain the refcount. That's next. Hardest part of this was debugging the assume-console scenarios in layer 85. That took some detailed manual diffing of traces (because the output of diff was no good). New tracing added in this commit add 8% to .traces LoC. Commented out trace() calls (used during debugging) make that 45%.
* 2576 - distinguish allocated addresses from othersKartik K. Agaram2016-01-191-3/+5
| | | | | | | | | | | | | | | | This is the one major refinement on the C programming model I'm planning to introduce in mu. Instead of Rust's menagerie of pointer types and static checking, I want to introduce just one new type, and use it to perform ref-counting at runtime. So far all we're doing is updating new's interface. The actual ref-counting implementation is next. One implication: I might sometimes need duplicate implementations for a recipe with allocated vs vanilla addresses of the same type. So far it seems I can get away with just always passing in allocated addresses; the situations when you want to pass an unallocated address to a recipe should be few and far between.
* 2555Kartik K. Agaram2016-01-111-2/+2
|
* 2475 - allow addresses to be converted to numbersKartik K. Agaram2015-11-271-2/+2
| | | | It's just the other direction we want to avoid.
* 2473 - bad idea to use /raw with multiple intentionsKartik K. Agaram2015-11-221-6/+6
| | | | | /raw is to express absolute addresses /unsafe is to sidestep type-checking in test setup
* 2459Kartik K. Agaram2015-11-181-0/+12
|
* 2450 - another pesky bugKartik K. Agaram2015-11-151-0/+12
|
* 2399 - consistent debug_string vocabularyKartik K. Agaram2015-11-081-2/+2
|
* 2377 - stop using operator[] in mapKartik K. Agaram2015-11-061-26/+26
| | | | | | | | | | | | | | | | I'm still seeing all sorts of failures in turning on layer 11 of edit/, so I'm backing away and nailing down every culprit I run into. First up: stop accidentally inserting empty objects into maps during lookups. Commands run: $ sed -i 's/\(Recipe_ordinal\|Recipe\|Type_ordinal\|Type\|Memory\)\[\([^]]*\)\] = \(.*\);/put(\1, \2, \3);/' 0[1-9]* $ vi 075scenario_console.cc # manually fix up Memory[Memory[CONSOLE]] $ sed -i 's/\(Memory\)\[\([^]]*\)\]/get_or_insert(\1, \2)/' 0[1-9]* $ sed -i 's/\(Recipe_ordinal\|Type_ordinal\)\[\([^]]*\)\]/get(\1, \2)/' 0[1-9]* $ sed -i 's/\(Recipe\|Type\)\[\([^]]*\)\]/get(\1, \2)/' 0[1-9]* Now mu dies pretty quickly because of all the places I try to lookup a missing value.

|
* 2270Kartik K. Agaram2015-10-121-1/+1
| | | | Thanks Caleb Couch.
* 2258 - separate warnings from errorsKartik K. Agaram2015-10-061-31/+31
| | | | | | | 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.
* 2242Kartik K. Agaram2015-10-051-3/+52
|
* 2228 - index-checking for arraysKartik K. Agaram2015-10-011-23/+47
|
* 2226 - standardize warning formatKartik K. Agaram2015-10-011-9/+9
| | | | | | | | 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?
* 2218 - check types in instructions much earlierKartik K. Agaram2015-09-301-2/+2
| | | | | | | | | Front-loads it a bit more than I'd like, but the payoff is that other recipes will now be able to describe the type checks right next to their operation. I'm also introducing a new use of /raw with literals to indicate unsafe typecasts.
* 2214Kartik K. Agaram2015-09-281-28/+0
|
* 2213 - start moving type checks out of 'run'Kartik K. Agaram2015-09-281-0/+28
| | | | | That way we only have to check each static instruction once, rather than every time it runs.
* 2199 - stop printing numbers in scientific notationKartik K. Agaram2015-09-141-2/+2
| | | | | | | | | | | 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.
* 2064Kartik K. Agaram2015-08-241-1/+1
| | | | Adjust spaces in 'stash'.
* 2003Kartik K. Agaram2015-08-141-5/+0
| | | | Minor issue in building until just layer 32.
* 2000 - stop constantly copying large arrays aroundKartik K. Agaram2015-08-141-3/+10
|
* 1994 - new primitive: 'create-array'Kartik K. Agaram2015-08-141-24/+78
| | | | | Not strictly necessary, but it might help me stage the introduction of arrays and 'new'.
* 1988 - handle reagents without typesKartik K. Agaram2015-08-131-3/+3
| | | | | | This can happen if 'canonize' fails. Make sure it doesn't kill mu. Thanks Caleb Couch.
* 1975 - let's start using traces in lessonsKartik K. Agaram2015-08-101-0/+10
| | | | | More friendly way to 'stash' stuff in the trace so that you can toggle lines of code to see their stashed traces.
* 1962Kartik K. Agaram2015-08-091-2/+2
| | | | Standardize test names.
* 1950Kartik K. Agaram2015-08-071-7/+7
|
* 1923Kartik K. Agaram2015-08-021-4/+3
| | | | | | | | | | Still iterating on the right way to handle incorrect number of ingredients. My first idea of creating null results doesn't really work once they're used in later instructions. Just add a warning at one place in the run loop, but otherwise only add products when there's something to save in them. Undoes some work around commit 1886.
* 1909 - clean up all null pointers of that ilkKartik K. Agaram2015-07-311-6/+16
|
* 1886 - gracefully handle malformed ingredientsKartik K. Agaram2015-07-291-3/+4
| | | | | | | | For example: x:number <- index y:address:array:number, 3 (forgetting to do a lookup) Thanks Caleb Couch.
* 1882Kartik K. Agaram2015-07-291-6/+6
|
* 1879 - types required at first mention of a nameKartik K. Agaram2015-07-281-1/+1
| | | | That should avoid many issues with typos in names.
