2016-08-28zlib: Fix arg error checkingSteve Bennett1-1/+5
It is wrong to call Jim_WrongNumArgs() with argc == 0. Instead -1 should be returned from the subcmd function to display the standard error message. Add a --maintainer check for this condition in Jim_WrongNumArgs() and fix the zlib unit tests. Signed-off-by: Steve Bennett <steveb@workware.net.au>
2016-08-17Don't unconditionally define _GNU_SOURCESteve Bennett1-3/+10
Also, fix build if JIM_OPTIMIZATION is disabled Signed-off-by: Steve Bennett <steveb@workware.net.au>
2016-08-17expr: fixes for pow/**Steve Bennett1-22/+53
- integer version is much faster - handle -ve numbers - ** is right associative - add tests from Tcl 8.6 Signed-off-by: Steve Bennett <steveb@workware.net.au>
2016-08-17expr: fix adjacent terms in function callsSteve Bennett1-90/+91
Previously two adjacent terms were incorrectly accepted, such as in pow(2 3) Correctly generate an error in this case and improve the error message when an expression fails to parse correctly. Signed-off-by: Steve Bennett <steveb@workware.net.au>
2016-08-17expr: Improve mathfunc handlingSteve Bennett1-17/+50
Previously math functions with multiple arguments were handling poorly. For example: pow(1.0 + 3.0 - 2, .8 * 5) was evaluated as: pow(1.0 + 3.0, 2 - .8 * 5) Now commas correctly separate function parameters. Also, the error messages are more consistent and informative in the case of an invalid expression. Update and re-enable tests in tests/expr-old.test accordingly Signed-off-by: Steve Bennett <steveb@workware.net.au>
2016-08-17expr: add support for atan2, hypot and fmodSteve Bennett1-58/+63
And enable some more math tests Signed-off-by: Steve Bennett <steveb@workware.net.au>

2016-03-27jim: Jim_ScriptIsComplete() now takes an objectSteve Bennett1-32/+27
Rather than taking a string and a length, it is simpler and more efficient to take a Jim_Obj Signed-off-by: Steve Bennett <steveb@workware.net.au>

2015-06-03chained tailcalls were not always being runSteve Bennett1-30/+20
There is no need to protect against merging tailcalls across uplevel since any tailcalls should already be fully resolved. This fixes a problem with the following only running one loop: foreach a {b c d} { command-with-tailcall $a } In particular: dict for {a b} {1 2 3 4} { puts $a,$b } Reported-by: Jon Povey <jon.povey@emsolutions.com.au> Signed-off-by: Steve Bennett <steveb@workware.net.au>
2015-01-16Improve performance of script validation commitSteve Bennett1-43/+38
Commit 7edde0797 inadvertently reduced performance of the script evaluation fast path. Rename Jim_GetScript() to JimGetScript() - always returns a script, even on parse failure. Now JimValidScript() checks the script for parse error and generates the error message if necessary. Signed-off-by: Steve Bennett <steveb@workware.net.au>
2014-12-31Throw an error when parsing a bad scriptSteve Bennett1-23/+30
If a script has a missing bracket (for example), currently it is silently ignored, except by [source] Signed-off-by: Steve Bennett <steveb@workware.net.au>

2014-10-11jim.c: string to double conversion error messageSteve Bennett1-1/+1

2014-10-10alias: don't rely on internal list never shimmeringSteve Bennett1-1/+4
It is possible for the alias prefix to shimmer, especially if the prefix is a list with a single element Signed-off-by: Steve Bennett <steveb@workware.net.au>

2014-03-19jim.c: Restore errors for Jim_EvalFile()Steve Bennett1-5/+8

2014-03-18jim.c: check for missing quotes, etc. in eval, exprSteve Bennett1-56/+87
Throw an error if a script or expression is missing a trailing bracket, brace or quote rather than simply ignoring the error. Reported-by: Florian Schäfer <florian.schaefer+github@gmail.com> Signed-off-by: Steve Bennett <steveb@workware.net.au>
