Daniel Shahaf 291940bae6 unposted (cf. 51016): Add a test case for underscore-followed-by-digits in math context. 2022-11-23 14:22:02 +00:00
Peter Stephenson af1c009c3e 46079: Ignore double quotes in math expressions. 
Treat as white space.

This is required for compatibility and previously had no use in zsh
as it generated an error.

Peter Stephenson 225b35c907 43261: Fix unary minus with base.

Oliver Kiddle a93abe1170 42488: test cases for 42369 and address some issues in the code 2018-05-13 10:13:42 +02:00
Peter Stephenson ea5b38935a 41641: Some math operations shouldn't be lvalues. 
This includes pre- and post- increment and decrement.  Simply
mark all values after operations as rvalues.

Peter Stephenson 524f802610 37489, tweaked: with POSIX_IDENTIFIERS create math var as scalar 2016-01-03 18:57:10 +00:00
Peter Stephenson 099e717c15 35359: Improved math parsing and errors. 
Check for bogus trailing ")" at end of top-level parse.

Extend some math error messages to indicate they are math errors.

Peter Stephenson 0da0a0b9c7 35153: nested math substitution 2015-05-15 10:19:53 +01:00
Peter Stephenson 2ef4b38461 34892 (slightly tweaked): math evaluation fix 
An empty expression resulting from substitution includes a
Nularg, which needs handling the same as an empty string.

Peter Stephenson 6fa63a0ce2 34606: fix up nested arithmetic substitution 
Arithmetic within a parameter substitution is a special
case that needs fixing with the introduction of the new
Inparmath token.

Add test.

Peter Stephenson 52e938bac9 34570: Another nasty command / math substituion thing. 
Mark arithmetic substitutions with tokens to make sure the substitution
go knows what to do.  Before it was guessing by counting the
parentheses at the end.
