Sample Program:

"""
100 PRINT "HELLO, WORLD!"

"""

This crashes with:

Variable names with line number cross-reference.

Goal here is that parsing '1' versus '1000' is a bit faster.

Given the B or BAS token stream, detokenize Applesoft programs. Should recognize binary components due to gaps in basic code and export as companion binary.

Likely requires change to subcommands?

Line numbers used in:

• GOSUB n
• GOTO n
• IF ... THEN n
• LIST n [ ,m ]
• ON x GOTO n, m, ...
• ON x GOSUB n, m, ...
• ONERR GOTO n
• RUN n

Would need to support code like:

label:
    print "Hi"
    goto label

Which would then get transpiled into:

10 PRINT "Hi" : GOTO 10

Going to try http://picocli.info/.

Noting that current versions of Eclipse no longer reliably recognize older versions of Gradle projects reliably. Bump embedded version and adjust builds accordingly.

Currently if you typo something in the input program and tokenization fails, the resulting error message is not very informative about where is the problem. e.g. you get a nested exception where the lowest level is:

Caused by: java.io.IOException: Unknown! ttype=63, nval=30.000000, sval=null

at picocli.CommandLine.execute(CommandLine.java:830)

which is trying to tell me that there is an unexpected '?' character (ASCII 63) somewhere on line 30.

Needs to be aware of line numbers and references.

Maybe this means flesh out the AppleCommander AppleSingle capabilities and make it an independent project.

This project includes the GPL 3 LICENSE file, but does not indicate whether it is licensed under GPL 3 only, or GPL 3 or later. Could you indicate this somewhere, maybe in the readme? Thanks.

Thank you for making these utilities; I'm delighted. The $embed functionality is exactly what I was looking for, unfortunately I'm having trouble getting it to work with bt 0.3.1.

printf $'\x60' > rts
echo '1 PRINT "BEFORE CALL"' > hello
echo '2 $embed file="rts", moveto="$300"' >> hello
echo '3 PRINT "AFTER CALL"' >> hello
applecommander -dos140 test.dsk
bt hello --applesingle --stdout | applecommander -as test.dsk hello

If I run this program:

]RUN HELLO
BEFORE CALL

?UNDEF'D STATEMENT ERROR IN 2

If I list this program:

]LIST

 1  PRINT "BEFORE CALL"
 2  CALL 2110: GOTO 3
 15493  SPEED= DEL = SPEED= ? DEL
     > SPEED= DEL ? SPEED=
 937  DEL C COLOR=
 24830
 17985 TER CALL"

A lowercase variable name causes a ?SYNTAX ERROR!

If this goes to Maven Central, should the project shift to Gradle like the rest of the projects?

Future idea. Need to build expression tree and reduce.

This would make all floating-point conversation work be done once.

Presumably these are all triggered by repeated colons in the source TEXT::HOME => TEXT, empty statement, HOME.
