Don't parse _123 as a decimal number
 2023-02-03 15:27:49 -08:00
jn
99438e5997 Don't parse _123 as a decimal number 
Instead require that decimal numbers start with a digit.

This fixes the detection of things like _L4 and _4 as labels.

Merge pull request #9 from neuschaefer/dev 
Better error handling and nop.8
 2023-02-01 14:53:42 -08:00
jn
0c47ce79af Allow specifying width on zero-operand instructions 
nop.8 exists and is valid, so fox32asm should assemble it.

It might be a good idea to reject some invalid instructions, though,
such as out.8.

	note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

e59e0ef83d Reset CURRENT_SIZE to Size::Word before parsing a data directive 
Previously, the following program:

	push.16 0
	data.16 0

... crashed fox32asm:

	thread 'main' panicked at 'internal error: entered unreachable code', src/main.rs:620:22
	stack backtrace:
	   0: rust_begin_unwind
		     at /usr/src/rustc-1.63.0/library/std/src/panicking.rs:584:5
	   1: core::panicking::panic_fmt
		     at /usr/src/rustc-1.63.0/library/core/src/panicking.rs:142:14
	   2: core::panicking::panic
		     at /usr/src/rustc-1.63.0/library/core/src/panicking.rs:48:5
	   3: fox32asm::parse_data
	   4: fox32asm::build_ast_from_expression
	   5: fox32asm::main
	note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

The issue in line 620 is that parse_data expects a constant in the form
of AstNode::Immediate32, but finds an AstNode::Immediate16, because
CURRENT_SIZE was previously set to Half. Set CURRENT_SIZE to Word when
starting to parse a new data directive, in order to fix this issue.

Fixes #4

eb32be33c8 Add data.strz directive for zero-terminated strings 
A common pattern in fox32 software is this:

	data.str "Some string here" data.8 0

i.e. a zero- or NUL-terminated string. To make such strings easier to
write, introduce a new directive data.strz, which adds the zero byte
automatically:

	data.strz "Some string here"
