* | * generic/tclCompExpr.c (ParseExpr): While adding comments todgp2007-07-171-202/+251
| | | | | | | | | | | | explain the operations of ParseExpr(), made significant revisions to the code so it would be easier to explain, and in the process made the code simpler and clearer as well.

| | | | | | | | | | | | * tests/parseExpr.test: Several tests of syntax error messages to check that when expression substrings are truncated they leave visible the context relevant to the reported error.

| | | | | | | | common code for reporting syntax errors in LEAF elements.
* | * generic/tclCompExpr.c: Added a "parseOnly" flag argument todgp2007-07-111-49/+29
| | | | | | | | | | | | | | | | | | | | | | ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an end goal of filling a Tcl_Parse with Tcl_Tokens representing the parsed expression, or TclCompileExpr() with the goal of compiling and executing the expression. In the latter case, more aggressive conversion of QUOTED and BRACED lexeme to literals is done. In the former case, all such conversion is avoided, since Tcl_Token production would revert it anyway. This enables simplifications to the GenerateTokensForLiteral() routine as well.

| | | | | | | | | | | | | | | | to be stored directly in the parse tree. There's no memory cost to this addition, since that memory would have been lost to alignment issues anyway. Also, converted precedence definitions and lookup tables to use symbolic constants instead of raw number for improved readability, and continued extending/improving/correcting comments.

TclStackFree now takes a (void *) argument which is the pointer intended to be freed. TclStackFree will panic if that's not actually the memory the call will free.

This addresses most issues in [RFE 1517602] Assuming no performance disasters result from this, much dead code supporting the other implementation might now be removed.
