2010-10-15Use $::env to build environment for execSteve Bennett1-0/+39

Also, double parsing now allows trailing white space Signed-off-by: Steve Bennett <steveb@workware.net.au>
2010-10-15Clean up the indentation messSteve Bennett3-138/+39

2010-10-15Improvements to 'file mkdir', 'file delete'Steve Bennett1-0/+65
file mkdir will now create intermediate directories file delete can now also delete empty directories Signed-off-by: Steve Bennett <steveb@workware.net.au>
2010-10-15Improvements to catch, return, signal, trySteve Bennett5-60/+148
Improve the ability to rethrow errors * Allow return to rethrow an error by accepting '-errorinfo stacktrace' * Also, 'catch ... opts' now also stores opts(-errorinfo) on error * Use these to provide better stack traces from 'case' and 'try' * Implement 'return -level' Make try/on/finally more Tcl 8.6 compatible * With support for 'on' handlers and docs Add support for catch options to try * Otherwise it's hard to use try to catch signals Improvements to signal handling * catch -signal now sets a list of the handled signals as the result * catch -signal won't execute the body at all if a handled signal is pending * up to 64 (jim_wide) signals can now be handled * if catch -signal is nested, the innermost catch will catch the error * new 'signal catch' allows ignored/blocked signals to be examined and cleared. * update docs on signal handling exec should indicate which signal killed the child Signed-off-by: Steve Bennett <steveb@workware.net.au>

2010-10-15Simplify and speed up exprSteve Bennett2-1/+8
*: Reuse the ParseTokenList/ScriptToken machinery for 'expr' *: This is simpler than managing separate opcode/obj arrays *: expr opcodes are now in the same namespace as token types *: expr identifies int and double during parsing *: Move the 'while' common expr optimisations into Jim_EvalExpression *: Add a special trueObj and falseObj to help with these boolean optimisations *: Add lazy versions as the byte code is created instead of at the end *: Avoid repeated conversion attempts to int *: Once an object fails conversion to int and succeeds conversion to double, invalidate the string rep so the int conversion attempt no longer happens *: Also, avoid converting non-ints to int in expression optimisation *: No need for a string token for SEP and EOL tokens *: Fix shimmering of int -> double *: When an int shimmers to a double during an expression, remember that the value was originally an int (via a new type, coerced double)

2010-10-15Fix many problem with expr evaluationSteve Bennett2-1/+892
*: Import Tcl expr tests (expr-old.test) and fix things: *: !double should be boolean (int) *: double&&double and double||double should be boolean (int) *: 2.34e+1 and 2.0e2 are an acceptable double values *: precedence of && and || is not equal *: precedence of ? and : is not equal *: expression "2:3" is invalid *: lazy evaluation involving multiple && and || was quite wrong *: Fix unary minus wrt subexpressions. e.g. -(-1.5) *: Also add support for functions: int, double, abs, round *: Fix lazy evaluation of ternary operator *: Error on missing ?, missing : *: Fix double unary minus *: Add unary plus *: Fix parsing of double with no '.' before 'e'.
