scdoc: New release? 9 days ago

From JTurtle to ~sircmpwn/public-inbox

Congrats on Hare 0.24.0!

scdoc is the only optional dependency for a complete Hare install, and
the only one that didn't get a stable release along with Hare. Since the
last release two years ago, there have been a few bug fixes, man page
corrections, and code cleanup. I think it's time to do a 1.11.3 release.

But i've never packaged software, sorry if there's a good reason it
hasn't happened.

[PATCH harec v2] lex: allow digit separators 3 months ago

From jturtle to ~sircmpwn/hare-dev

Allows the separator byte '_' to be placed between digits.

Signed-off-by: jturtle <jturtl@pm.me>
Implements suggested changes from v1, plus more tests to handle all the edge
cases i could think of. Separators may be placed between two valid
digits, except in type suffixes (like '1u3_2').

Re: Proposal: digit separator 3 months ago

From JTurtle to ~sircmpwn/hare-dev

My first patch was rejected, which is good because i submitted it
earlier than i should. I'll wait for an authoritative "we're ready, do
it" from someone before trying that stunt again.

I found a more concise way to explain separator restrictions that covers
all the cases (i hope).

"Separators may only be placed between two valid digits, and not within
a type suffix."
Here's a list of invalid numbers according to this rule:
- 1__0
- 0x_ABACA
- 0u6_4
- 0u_64

Re: [PATCH harec] lex: allow digit separators 3 months ago

From JTurtle to ~sircmpwn/hare-dev

Thank you, i'll try again the suggested way and move the tests.

I didn't consider the exponents, and this patch allows separators before
and immediately after the exponent marker in base-10 and base-16, which
is probably not desired.

Underscores before the base specifier, like `0_xFF` would be caught as
"Leading zero in base 10 literal", which isn't the ideal error message
but fixing that seems like a headache.

I should have waited for more discussion around the specifics before
submitting a patch :P

[PATCH harec] lex: allow digit separators 3 months ago

From jturtle to ~sircmpwn/hare-dev

Long number literals can be broken up by `_`. For example: `1_000_000`.
Added some tests too. This isn't covered by the spec yet.

Re: Proposal: digit separator 3 months ago

I'm glad everyone's on board.

Neither Rust, C/C++, nor Zig enforce separating by
hundreds/thousands/nibbles/bytes, and i don't think we should either.

That's the state my implementation is in. But after making it, i've come
up with some reasonable restrictions on where the separator may go:

Proposal: digit separator 3 months ago

From JTurtle to ~sircmpwn/hare-dev

Pre-emptive apologies, if it would have been better to post this in hare-rfc instead.

Digit separators are useful for breaking up long numbers, e.g. in english: 1,000,000,000 is easier to visually parse than 1000000000. They're common in modern programming languages. Even C has a digit separator after C23. 

The most common separator is `_`, as in `1_000_000_000`.
C and C++ use `'` as the separator, as in `1'000'000'000`.

I propose that Hare allows the use of a separator, probably `_`, in integer (and float?) literals. This is a non-breaking change that will ideally only affect the lexer.

Some details worth clarifying before implementation:
- Allow more than one separator in a row, like `1__000_____0`?
- Allow trailing separators, like `1_000_`?
- Allow separators immediately after an integer prefix, like `0x_ACAB`?
- Allow separators before a type suffix, like `420_i32`?

[PATCH scdoc] Emit '\e' instead of '\\' 4 months ago

From jturtle to ~sircmpwn/public-inbox

I noticed that the rc shell's docs are messed up when using
man-db, but fine with mandoc. '\e' is the standard way to emit a
backslash, and the way that makes man-db not cry.

[PATCH] Fix for loops in interactive mode 4 months ago

From jturtle to ~sircmpwn/rc-devel

Using a for loop in interactive mode will crash because `state.ctx` is empty.
An implied for loop over $*, like `for (arg) echo $arg` would crash as well
because $* is not set in interactive mode.

[PATCH gsp] Fix printing classes and attrs 4 months ago

From jturtle to ~mango/public-inbox

Well well well, here we are again.
Iterate over the `nClasses` list instead of every attr after printing
the classes.

With all due respect, you should consider writing a test suite to catch
silly errors like this.
