| 2022-07-03 | Update a comment in compare.csc. | Rose Hogenson | 1 | -4/+0 | |
| 2022-07-03 | Add a diff library. | Rose Hogenson | 12 | -191/+549 | |
| I was hesitant to add a diff library, but it was surprisingly easy. A straightforward application of dynamic programming. | |||||
| 2022-07-02 | Write closure conversion. | Rose Hogenson | 8 | -163/+356 | |
| I desperately need a diffing library. | |||||
| 2022-07-01 | Add update conversion. | Rose Hogenson | 3 | -145/+345 | |
| Now variables can't be updated after they're created, so they can be freely copied into closures. | |||||
| 2022-06-30 | Remove unsafe code. | Rose Hogenson | 1 | -57/+48 | |
| I'm partially doing it because I'm not sure if what I had was really safe, but also it just looks much cleaner this way. | |||||
| 2022-06-30 | Add a function for getting the gensym ID. | Rose Hogenson | 1 | -2/+3 | |
| 2022-06-29 | Add pattern matching for record types. | Rose Hogenson | 5 | -152/+233 | |
| I like scheme because it's possible to add any convenient language feature I can think of. | |||||
| 2022-06-28 | Improve CPS. | Rose Hogenson | 9 | -431/+357 | |
| Goodbye soup. Thanks to "Compiling with Continuations" by Appel. | |||||
| 2022-06-26 | Finish CPS. | Rose Hogenson | 6 | -12/+182 | |
| Wow we actually finished CPS. Next is closure conversion, then codegen, and then we should be able to run some end to end tests. Then we can look at garbage collection, and from there continue building features down the long road to self hosting. | |||||
| 2022-06-26 | More CPS. | Rose Hogenson | 3 | -62/+151 | |
| I improved the abstraction in to-cps. | |||||
| 2022-06-25 | More CPS. | Rose Hogenson | 5 | -4/+72 | |
| 2022-06-25 | Continue work on continuation passing style. | Rose Hogenson | 6 | -43/+235 | |
| 2022-06-21 | Add shell.nix. | Rose Hogenson | 1 | -0/+5 | |
| 2022-06-21 | More progress on CPS. | Rose Hogenson | 3 | -69/+57 | |
| 2022-06-21 | Comment expand-body. | Rose Hogenson | 1 | -0/+1 | |
| 2022-06-21 | Start CPS :) | Rose Hogenson | 2 | -0/+30 | |
| 2022-04-22 | Add notes on the build process and CLI interface. | Rose Hogenson | 1 | -0/+38 | |
| 2022-04-22 | Small update. | Rose Hogenson | 1 | -2/+2 | |
| 2022-04-22 | Fix image caption. | Rose Hogenson | 1 | -2/+4 | |
| I think this will look the best, just repeating the same information in the alt text and in the main text. The pandoc generated version will be slightly repetitive, but it's not too bad. | |||||
| 2022-04-22 | Add a diagram of the compiler phases. | Rose Hogenson | 2 | -1/+298 | |
| 2022-04-22 | Improve the README for Github. | Rose Hogenson | 1 | -3/+3 | |
| 2022-04-22 | Update the README for Github markdown. | Rose Hogenson | 1 | -12/+8 | |
| 2022-04-22 | Update the README. | Rose Hogenson | 1 | -3/+351 | |
| 2022-04-22 | Remove the void type. | Rose Hogenson | 3 | -23/+11 | |
| Why have void? We will just use #f. | |||||
| 2022-04-07 | Add libraries. | Rose Hogenson | 3 | -126/+189 | |
| Gone is toplevel. Now everyone lives in a library. | |||||
| 2022-04-02 | Write a test for case-lambda. | Rose Hogenson | 3 | -18/+49 | |
| I'm realizing that I should have started with builtin-exit and implemented the hard stuff later. | |||||
| 2022-03-31 | Improvements in macros and IR1. | Rose Hogenson | 4 | -184/+171 | |
| We're omitting libraries for now, and I'll add them in later. | |||||
| 2022-03-31 | Allow overriding the cmp function in assert-equal. | Rose Hogenson | 2 | -93/+6 | |
| 2022-03-03 | Write the compiler frontend. | Rose Hogenson | 4 | -54/+186 | |
| 2022-03-03 | Start the garbage collector. | Rose Hogenson | 7 | -77/+561 | |
| I don't think we finished it, but I wrote this code a while ago and I'm just trying to get it committed. | |||||
| 2022-01-25 | Nitpick on loop style. | Rose Hogenson | 1 | -3/+4 | |
| 2022-01-25 | Use an exception for loop return. | Rose Hogenson | 1 | -18/+12 | |
| This makes everything a lot easier, as it handles nested loops automatically. My brain wave was storing the returned values in a thunk. | |||||
| 2022-01-25 | Fix the bugs in loop. | Rose Hogenson | 2 | -44/+230 | |
| It works! Sometimes it emits nested loops! | |||||
| 2022-01-24 | Implement lambda? | Rose Hogenson | 2 | -12/+209 | |
| 2022-01-24 | Finish the loop macro. | Rose Hogenson | 3 | -164/+362 | |
| I also cleaned everything up a lot. Maybe there are still bugs because the test coverage is awful, but for now I'm happy to be done. | |||||
| 2022-01-22 | Store the list length in sort. | Rose Hogenson | 1 | -8/+12 | |
| Computing length each time is very unnecessary. | |||||
| 2022-01-22 | Add a loop macro. | Rose Hogenson | 3 | -12/+313 | |
| 2022-01-15 | Finish the macro expander. | Rose Hogenson | 6 | -105/+501 | |
| It works!! At least it passes all the test cases. Next I will: 1. finish the builtins, 2. add a conversion to IR2 in continuation passing style, 3. add a compiler from IR2 to bytecode, 4. and add an option to the frontend compiler to generate a standalone executable. | |||||
| 2022-01-14 | Write a first draft macro expander. | Rose Hogenson | 6 | -161/+414 | |
| Committing it because it compiles. I have to write tests and debug it still. | |||||
| 2022-01-13 | Rewrite match to use exceptions. | Rose Hogenson | 1 | -17/+43 | |
| This makes the control flow more clear, and eliminates the need to scan the pattern twice. It also makes it easier to add new forms by consolidating the pattern logic in one procedure. | |||||
| 2022-01-13 | Use := instead of = for variable assignment. | Rose Hogenson | 1 | -1/+1 | |
| I was reading about the difference, and := does what you want more often than not. | |||||
| 2022-01-13 | Generalize the hash map. | Rose Hogenson | 3 | -35/+48 | |
| Before we were assuming keys could be compared with eqv?. But it seems like that assumption isn't true when we want to hold identifiers in the hash map. | |||||
| 2022-01-11 | Add a README. | Rose Hogenson | 1 | -0/+5 | |
| 2022-01-11 | Move scheme compiler into a separate directory. | Rose Hogenson | 27 | -0/+0 | |
| 2022-01-11 | Add a first implementation of a macro expander. | Rose Hogenson | 3 | -0/+422 | |
| This half-finished macro expander is the most satisfying piece of code I have ever written. | |||||
| 2022-01-11 | Make bindings visible while a guard is evaluated. | Rose Hogenson | 2 | -5/+15 | |
| The current implementation repeats the bindings twice, but I guess it's fine. It seems to work. | |||||
| 2022-01-11 | Add guards to the match syntax. | Rose Hogenson | 2 | -1/+20 | |
| I'm not sure the syntax is great, but it's very helpful to have. | |||||
| 2022-01-09 | Write the linker. | Rose Hogenson | 13 | -102/+450 | |
| 2022-01-09 | Remove str- prefixes from the strings library. | Rose Hogenson | 3 | -47/+45 | |
| Not very scheme. | |||||
| 2022-01-09 | Redo the testing framework. | Rose Hogenson | 9 | -637/+310 | |
| We can lean more on the power of scheme to make the testing framework a little less verbose. | |||||
