chromatopelma - Partial r7rs implementation with a focus on ease of implementation and a reusable library. Work in progress.

Age	Commit message (Collapse)	Author	Files	Lines
2022-09-02	Fix bugs with recursive macros and empty template.	Rose Hogenson	2	-38/+91

2022-09-02	Undo the hacky list constant changes.	Rose Hogenson	2	-41/+4
	We will eventually implement list constants using some kind of rodata.
2022-09-01	Fix some bugs in macros, and add list constants.	Rose Hogenson	2	-94/+236

2022-08-27	Use reg 255 for swapping.	Rose Hogenson	2	-3/+3
	I wanted to use the top reg, for some reason I thought at the time that 127 was the biggest 8-bit number. Obviously it's 255.
2022-08-27	Enable nil constants.	Rose Hogenson	1	-2/+3

2022-08-27	Implement multiple return values.	Rose Hogenson	5	-82/+120

2022-08-23	Change argument passing to use lists.	Rose Hogenson	5	-329/+87
	Using vectors is just horribly complicated combined with builtins like apply, or procedures that take a rest parameter. Now we pass all arguments in a list. Hopefully optimization can undo this for known functions in the future.
2022-08-23	Insert references, not values into the map.	Rose Hogenson	1	-7/+4
	This fixes a bug in compiler.csc.
2022-08-22	Add a few primitive list operations.	Rose Hogenson	1	-4/+14

2022-08-12	Fix bugs in the macro expander.	Rose Hogenson	2	-84/+125
	Now I'm following the rule that you should ignore marks that were added after the binding was defined. I also introduced a lexical environment to handle lambdas.
2022-08-10	Subtract int-min instead of adding int-max + 1.	Rose Hogenson	1	-11/+3

2022-08-09	Fix a few small bugs.	Rose Hogenson	2	-3/+3
	N lines of code will have about 2N bugs.
2022-08-08	Fix the bugs in the number library.	Rose Hogenson	1	-170/+218
	I did some extensive manual testing. Hopefully there are no bugs left :)
2022-08-08	Unexport case-lambda.	Rose Hogenson	1	-1/+2
	case-lambda is actually defined in the (scheme case-lambda) library, but it's too convenient so I'm just going to define two copies.
2022-08-07	Misc test fixup in the compiler.	Rose Hogenson	5	-21/+28

2022-08-07	Add a needed import to 10-define.csc.	Rose Hogenson	1	-1/+2

2022-08-07	Add include-library-declarations.	Rose Hogenson	1	-13/+50

2022-08-07	Fix hoist.	Rose Hogenson	1	-2/+4
	Hoist needs to hoist the function bodies as well.
2022-08-07	Add int<? and eq?.	Rose Hogenson	1	-0/+5

2022-08-07	Fix a bug in expand-body for an empty body.	Rose Hogenson	1	-1/+2

2022-08-07	Define last-index.	Rose Hogenson	2	-0/+26

2022-08-07	Fix a typo in codegen.	Rose Hogenson	1	-3/+1

2022-08-07	Activate the new libraries.	Rose Hogenson	1	-1/+3

2022-08-07	Add numbers.	Rose Hogenson	1	-0/+821

2022-08-07	Add vectors.	Rose Hogenson	1	-0/+156

2022-08-07	Add map and for-each.	Rose Hogenson	1	-1/+35

2022-08-07	Fix a bug in the records library.	Rose Hogenson	1	-1/+2
	We have to check if it's a pointer before dereferencing.
2022-08-07	Add booleans.	Rose Hogenson	1	-2/+25

2022-08-05	Check that records are the correct type.	Rose Hogenson	1	-9/+15
	To avoid selecting the wrong field, or reading out of bounds, we should ensure that a record is the correct type before reading a field.
2022-08-05	Add more of the standard library.	Rose Hogenson	10	-386/+774

2022-08-05	Add call-with-values.	Rose Hogenson	2	-1/+21

2022-08-05	Add call-with-current-continuation.	Rose Hogenson	2	-0/+15

2022-08-04	Add if, and, or, when and friends.	Rose Hogenson	3	-2/+90

2022-08-04	Add begin.	Rose Hogenson	1	-1/+12

2022-08-04	Add if and set!.	Rose Hogenson	3	-5/+67

2022-08-03	Start the scheme base library.	Rose Hogenson	3	-0/+94

2022-08-01	Remove mutable globals.	Rose Hogenson	2	-7/+12
	Per a closer reading of R7RS, it's an error to mutate an imported binding with set!. My apologies to Guile when I said they had a bug.
2022-08-01	Modify the project structure.	Rose Hogenson	37	-0/+6441
	Now the lib directory contains what will eventually end up on the user's /usr/lib/csc. When I write make install, it will copy all of the .csc files from lib into the destination lib directory. This means I can start working on the standard library in lib/scheme.
