Implement support for bare vars by `math` This change allows you to type `math x + 3` rather than `math $x + 3`. Another step to resolving issue #3157. 2017-08-24 11:38:40 +08:00

[math] Remove more bare variable support Prior to this fix, a "bare variable" in math like 'x + 1' would be looked up in the environment, i.e. equivalent to '$x + 1'. This appears to have been done for performance. However this breaks the orthogonality of fish; performance is not a sufficient justification to give math this level of built-in power, especially because the performance of math is not a bottleneck. The implementation is also ugly. Remove this feature so that variables must be prefixed with the dollar sign and undergo normal variable expansion. Reading 'git grep' output does not show any uses of this in fish functions or completions. Also added to changelog.

Add some math tests for invalid inputs 2017-11-25 15:04:44 +08:00

[math] Better error for `2 - ` Instead of the catch-all, report too few arguments. 2018-02-26 20:46:01 +08:00			`math: Error: Too few arguments`
[math] Adjust tests for new error reporting This shows how it's still weird - "2 - " and "max()" return the same error. 2018-02-26 18:25:35 +08:00			`'2 - '`
			`^`
			`math: Error: Too few arguments`
			`'ncr(1)'`
			`^`
			`math: Error: Expression is bogus`
			`'max()'`
			`^`
			`math: Error: Too few arguments`
			`'sin()'`
			`^`
[math] Better error for `2 + 2 4` This now reports "TOO_MANY_ARGS" instead of no error (and triggering an assertion). We might want to add a new error type or report the missing operator before, but this is okay for now. 2018-02-26 21:00:29 +08:00			`math: Error: Too many arguments`
			`'2 + 2 4'`
			`^`
[math] Fail without arguments See #4768. 2018-03-02 05:27:24 +08:00			`math: Expected at least 1 args, got only 0`

[math] Add tests for runtime errors And fix "isinfinite" - it's called "isinf". 2018-03-08 01:13:26 +08:00			`math: Error: Result is too large`
			`'2^650'`
			`math: Error: Result is infinite`
