Basic (C64 v2): step0 This works with cbmbasic from https://github.com/mist64/cbmbasic. The cbmbasic interpreter needs to be on the PATH. The actually sources are .in.bas which are "compiled" to .bas using the qb2cbm.sh. qb2cbm.sh translates from a QBasic-ish format to a line numbered source with include files inlined (REM $INCLUDE: 'file.bas'). One additional advantage is that the *.in.bas versions can also be indented and qb2cbm.sh will remove the indenting in the translated code. 2016-09-05 04:23:56 +03:00			`#!/bin/bash`
Basic: Reduce GOSUB use. Partial self-host to step3 step4 runs out of space attempting to load the program. Step2 and step3 run out of memory (stack exhaustion) for more complicated forms. - Use GOTO with return label on our stack instead of GOSUB for: - APPLY function in types.in.bas - "apply", "map" and "swap!" core functions - Implement DO TCO. Change EVAL_AST to detect if we are called from DO and exit one element early. - Remove GOSUB recursion from EQUAL_Q - Inline PAIR_Q. Reduce REPLACE stack use. - Remove one level of GOSUB/stack by calling REP with GOTO - Simplify mal/step2_eval.mal to remove use of (or ) macro in eval_ast. - Fix ON GOTO/GOSUB line detection in basicpp 2016-10-25 07:29:27 +03:00			`cd $(dirname $0)`
basic: args file that doesn't rely on return value. Instead, the file itself does the def of -ARGS-. The behavior that the final value of a loaded file is returned is not necessarily something we want to assume. 2019-07-26 08:15:39 +03:00			`(echo "(def! -ARGS- (list $(for a in "${@}"; do echo -n " \"${a}\""; done)))") > .args.mal`
Basic: QBasic fixes/enabling. Recursive includes. Enable QBasic console mode usage and fix bugs in newline handling differences with C64 basic (cbm). To enable console mode for QBasic programs, have basicpp.py prefix the output with the QB64 specific console activation variables/functions. One change to basicpp.py to make this change more straightfowards is recursive includes so that includes can appear in more than just the top level step files. This allows us to conditionally include the right readline implementation. For QBasic in the special console mode (instead of the default full-screen UI mode) we need to use the LINE INPUT command in order to read input. 2017-09-15 07:50:15 +03:00			`case ${basic_MODE:-cbm} in`
