* 3233 - change how Mu escapes stringsKartik K. Agaram2016-08-201-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks Sam Putman for helping think through this idea. When you encounter a backslash, strip it out and pass through any following run of backslashes. If we 'escaped' a single following character like C, then the character '\' would be the same as: '\\' escaped once '\\\\' escaped twice '\\\\\\\\' escaped thrice (8 backslashes) ..and so on, the number of backslashes doubling each time. Instead, our approach is to make the character '\' the same as: '\\' escaped once '\\\' escaped twice '\\\\' escaped thrice ..and so on, the number of backslashes merely increasing by one each time. This approach only works as long as backslashes aren't also overloaded to create special characters. So Mu doesn't follow C's approach of overloading backslashes both to escape quote characters and also as a notation for unprintable characters like '\n'.

| | | | | Show more thorough information about instructions in the trace, but keep the original form in error messages.

* 2735 - define recipes using 'def'Kartik K. Agaram2016-03-081-9/+9
| | | | | | | | | | | | 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.

* 2681 - drop reagent types from reagent propertiesKartik K. Agaram2016-02-211-12/+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.

| | | | | | | Start using type names from the type tree rather than the property tree in most places. Hopefully the only occurrences of 'properties.at(0).second' left are ones where we're managing it. Next we can stop writing to it.
* 2677Kartik K. Agaram2016-02-201-1/+1
| | | | Include type names in the type tree. Though we aren't using them yet.

* 2685Kartik K. Agaram2016-02-191-3/+3
| | | | | | | | | | | | | | | | 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.
* 2614 - still fixing bugs with missing '['Kartik K. Agaram2015-12-021-2/+1
| | | | | | When skipping past some text (usually whitespace, but also commas and comments) I need to always be aware of whether it's ok to switch to the next line or not.
* 2454Kartik K. Agaram2015-11-171-5/+5
| | | | | | Another gotcha uncovered in the process of sorting out the previous commit: I keep using eof() but forgetting that there are two other states an istream can get into. Just never use eof().

* 2377 - stop using operator[] in mapKartik K. Agaram2015-11-061-1/+1
| | | | | | | | | | | | | | | | 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.
