Basic: add read-file. Misc basicpp space savings. - Add read-file which is similar to read-string but from a file name rather than a string. This allows steps 0-2 to load although each one eventuall crashes with out of memory after evaluating "123" a few times. - basicpp: - Renumber the line numbers so they are ordinally increasing. This saves 150 or so bytes because GOTO/GOSUB calls have smaller line numbers. - Shrink 'IF 123' -> 'IF123' for almost 300 byte savings.[:w - Simplify PR_MEMORY_SUMMARY output. Save 75 bytes - Add missing runtest.py change that allows basic tests to pass.

READ_TOKEN:
Basic: refactor of hashmaps, map loops, remove derefs. - Alternate memory layout of hash-maps: Instead of hash-maps being an alternating sequence of keys and values, combine the key/values into a single entry. In other words, switch from this: 8 -> next Z% index (0 for last) 14 key/value (alternating) To this: 8 -> next Z% index (0 for last) key value This requires refactoring of the sequence reader, EVAL_AST and especially DO_HASHMAP and DO_KEY_VALS. So that leads to the next big refactoring: - Change mapping/lapping constructs to share code: Several pieces of mapping/looping code have a common structure, so this moves that common structure to types.in.bas: MAP_LOOP_START, MAP_LOOP_UPDATE, MAP_LOOP_DONE. Then use this code in: - EVAL_AST - READ_SEQ_* - DO_MAP - DO_HASH_MAP - DO_KEYS_VALS This also fixes the issue that several of these looping constructs were creating new empty sequence entries instead of using the common ones at the beginning of memory. - Remove the use of DEREF_*. This isn't actually needed because we no longer create structure that refer to multiple levels of type 14 references. Replace DEREF_* with VAL_* which gets the value of a particular sequence element i.e. Z%(A+1,1). All together, the above changes save over 300 bytes. Also: - Fix empty nil/false/true entries so they are treated the same as other types of data with regards to reference counting and ALLOC/RELEASE. - Add a new memory summary function in debug.in.bas that just prints out free, value count, and references for the early scalar and empty list elements. Comment out the larger one. This saves about 90 bytes.

REM PRINT "READ_FORM T$: ["+T$+"]"
Basic: refactor memory layout. Use a one dimensional array for the Z% value array. This enables lists, vectors, environments and metadata pointers to all save off 1 word (2 bytes) of space. Split the memory init and functions into mem.in.bas. In addition, change type 14 to be metdata rather than any type 16-31. This change saves about 560 bytes (no second array dimension subscripts) and reduces Z% value usage by 10%-15%. Bump the number of Z% words by 200 (to 8591). This enables self-hosting up to step7 (without step8-stepA functions in core.mal).

Basic: more memory savings - Do the pop of CALL return value at the end of the subroutine (callee) rather than at the call point (caller) - shorten some character variables (CH$->C$, CH->C) - remove spaces after OPEN, GET - print REPL header directly in BASIC code Together saves 404 bytes of memory.

Basic: refactor of hashmaps, map loops, remove derefs. - Alternate memory layout of hash-maps: Instead of hash-maps being an alternating sequence of keys and values, combine the key/values into a single entry. In other words, switch from this: 8 -> next Z% index (0 for last) 14 key/value (alternating) To this: 8 -> next Z% index (0 for last) key value This requires refactoring of the sequence reader, EVAL_AST and especially DO_HASHMAP and DO_KEY_VALS. So that leads to the next big refactoring: - Change mapping/lapping constructs to share code: Several pieces of mapping/looping code have a common structure, so this moves that common structure to types.in.bas: MAP_LOOP_START, MAP_LOOP_UPDATE, MAP_LOOP_DONE. Then use this code in: - EVAL_AST - READ_SEQ_* - DO_MAP - DO_HASH_MAP - DO_KEYS_VALS This also fixes the issue that several of these looping constructs were creating new empty sequence entries instead of using the common ones at the beginning of memory. - Remove the use of DEREF_*. This isn't actually needed because we no longer create structure that refer to multiple levels of type 14 references. Replace DEREF_* with VAL_* which gets the value of a particular sequence element i.e. Z%(A+1,1). All together, the above changes save over 300 bytes. Also: - Fix empty nil/false/true entries so they are treated the same as other types of data with regards to reference counting and ALLOC/RELEASE. - Add a new memory summary function in debug.in.bas that just prints out free, value count, and references for the early scalar and empty list elements.

Basic: refactor memory layout. Use a one dimensional array for the Z% value array. This enables lists, vectors, environments and metadata pointers to all save off 1 word (2 bytes) of space. Split the memory init and functions into mem.in.bas. In addition, change type 14 to be metdata rather than any type 16-31. This change saves about 560 bytes (no second array dimension subscripts) and reduces Z% value usage by 10%-15%. Bump the number of Z% words by 200 (to 8591). This enables self-hosting up to step7 (without step8-stepA functions in core.mal).

So that leads to the next big refactoring: - Change mapping/lapping constructs to share code: Several pieces of mapping/looping code have a common structure, so this moves that common structure to types.in.bas: MAP_LOOP_START, MAP_LOOP_UPDATE, MAP_LOOP_DONE. Then use this code in: - EVAL_AST - READ_SEQ_* - DO_MAP - DO_HASH_MAP - DO_KEYS_VALS This also fixes the issue that several of these looping constructs were creating new empty sequence entries instead of using the common ones at the beginning of memory. - Remove the use of DEREF_*. This isn't actually needed because we no longer create structure that refer to multiple levels of type 14 references. Replace DEREF_* with VAL_* which gets the value of a particular sequence element i.e. Z%(A+1,1). All together, the above changes save over 300 bytes. Also: - Fix empty nil/false/true entries so they are treated the same as other types of data with regards to reference counting and ALLOC/RELEASE. - Add a new memory summary function in debug.in.bas that just prints out free, value count, and references for the early scalar and empty list elements. Comment out the larger one. This saves about 90 bytes.

The rest is put in *ARGV* and the first element is pulled out and used as the script name. - fix string reading/printing using new REPLACE function - add RE function to skip printing and to get back evaluated value (result must be freed by caller). Needed for step6 to get first argument pointer for scripting. - Sync earlier steps - add cons, first, rest to support parsing the command line. - eval is implemented as standard function in core.in.mal - fix println bug (using PR_STR rather than PR_STR_SEQ) - change sequence printing to save the initial sequence type on the stack and use that for the ending sequence delimeter. This way sequences of one type can still use the tail of sequences of a different type but still be considered the initial type.

Basic: refactor of hashmaps, map loops, remove derefs. - Alternate memory layout of hash-maps: Instead of hash-maps being an alternating sequence of keys and values, combine the key/values into a single entry. In other words, switch from this: 8 -> next Z% index (0 for last) 14 key/value (alternating) To this: 8 -> next Z% index (0 for last) key value This requires refactoring of the sequence reader, EVAL_AST and especially DO_HASHMAP and DO_KEY_VALS. So that leads to the next big refactoring: - Change mapping/lapping constructs to share code: Several pieces of mapping/looping code have a common structure, so this moves that common structure to types.in.bas: MAP_LOOP_START, MAP_LOOP_UPDATE, MAP_LOOP_DONE. Then use this code in: - EVAL_AST - READ_SEQ_* - DO_MAP - DO_HASH_MAP - DO_KEYS_VALS This also fixes the issue that several of these looping constructs were creating new empty sequence entries instead of using the common ones at the beginning of memory. - Remove the use of DEREF_*. This isn't actually needed because we no longer create structure that refer to multiple levels of type 14 references. Replace DEREF_* with VAL_* which gets the value of a particular sequence element i.e. Z%(A+1,1). All together, the above changes save over 300 bytes. Also: - Fix empty nil/false/true entries so they are treated the same as other types of data with regards to reference counting and ALLOC/RELEASE. - Add a new memory summary function in debug.in.bas that just prints out free, value count, and references for the early scalar and empty list elements.
