" Commands for recording the execution path. {{{2
"
" The Xpath/Xloop commands can be used for computing the eXecution path by
" adding (different) powers of 2 from those script lines, for which the
" execution should be checked. Xloop provides different addends for each
" execution of a loop. Permitted values are 2^0 to 2^30, so that 31 execution
" points (multiply counted inside loops) can be tested.
"
" Note that the arguments of the following commands can be generated
" automatically, see below.
"
" Usage: {{{3
"
" - Use XpathINIT at the beginning of the test.
"
" - Use Xpath to check if a line is executed.
" Argument: power of 2 (decimal).
"
" - To check multiple execution of loops use Xloop for automatically
" computing Xpath values:
"
" - Use XloopINIT before the loop.
" Two arguments:
" - the first Xpath value (power of 2) to be used (Xnext),
" - factor for computing a new Xnext value when reexecuting a loop
" (by a ":continue" or ":endwhile"); this should be 2^n where
" n is the number of Xloop commands inside the loop.
" If XloopINIT! is used, the first execution of XloopNEXT is
" a no-operation.
"
" - Use Xloop inside the loop:
" One argument:
" The argument and the Xnext value are multiplied to build the
" next Xpath value. No new Xnext value is prepared. The argument
" should be 2^(n-1) for the nth Xloop command inside the loop.
" If the loop has only one Xloop command, the argument can be
" ommitted (default: 1).
"
" - Use XloopNEXT before ":continue" and ":endwhile". This computes a new
" Xnext value for the next execution of the loop by multiplying the old
" one with the factor specified in the XloopINIT command. No Argument.
" Alternatively, when XloopINIT! is used, a single XloopNEXT at the
" beginning of the loop can be used.
"
" Nested loops are not supported.
"
" - Use Xcheck at end of each test. It prints the test number, the expected
" execution path value, the test result ("OK" or "FAIL"), and, if the tests
" fails, the actual execution path.
" One argument:
" Expected Xpath/Xloop sum for the correct execution path.
" In order that this value can be computed automatically, do the
" following: For each line in the test with an Xpath and Xloop
" command, add a comment starting with "X:" and specifying an
" expression that evaluates to the value contributed by this line to
" the correct execution path. (For copying an Xpath argument of at
" least two digits into the comment, press <C-P>.) At the end of the
" test, just type "Xcheck" and press <Esc>.
"
" - In order to add additional information to the test output file, use the
" Xout command. Argument(s) like ":echo".
"
" Automatic argument generation: {{{3
"
" The arguments of the Xpath, XloopINIT, Xloop, and Xcheck commands can be
" generated automatically, so that new tests can easily be written without
" mental arithmetic. The Xcheck argument is computed from the "X:" comments
" of the preceding Xpath and Xloop commands. See the commands and
" abbreviations at the beginning of this file.
"
" Implementation: {{{3

" in an extra Vim process, see ExtraVim below.

" ExtraVim() - Run a script file in an extra Vim process. {{{2
"
" This is useful for testing immediate abortion of the script processing due to
" an error in a command dynamically enclosed by a :try/:tryend region or when an
" exception is thrown but not caught or when an interrupt occurs. It can also
" be used for testing :finish.
"
" An interrupt location can be specified by an "INTERRUPT" comment. A number
" telling how often this location is reached (in a loop or in several function
" calls) should be specified as argument. When missing, once per script
" invocation or function call is assumed. INTERRUPT locations are tested by
" setting a breakpoint in that line and using the ">quit" debug command when
" the breakpoint is reached. A function for which an INTERRUPT location is
" specified must be defined before calling it (or executing it as a script by
" using ExecAsScript below).
"
" This function is only called in normal modus ("g:ExtraVimResult" undefined).

" Test 86: $VIMNOERRTHROW and $VIMNOINTTHROW support {{{1
"
" It is possible to configure Vim for throwing exceptions on error
" or interrupt, controlled by variables $VIMNOERRTHROW and
" $VIMNOINTTHROW. This is just for increasing the number of tests.
" All tests here should run for all four combinations of setting
" these variables to 0 or 1. The variables are intended for the
" development phase only. In the final release, Vim should be
" configured to always use error and interrupt exceptions.
"
" The test result is "OK",
"
" - if the $VIMNOERRTHROW and the $VIMNOINTTHROW control are not
" configured and exceptions are thrown on error and on
" interrupt.
"
" - if the $VIMNOERRTHROW or the $VIMNOINTTHROW control is
" configured and works as intended.
"
" What actually happens, is shown in the test output.
"
" Otherwise, the test result is "FAIL", and the test output describes
" the problem.
"
" IMPORTANT: This must be the last test because it sets $VIMNOERRTHROW and
" $VIMNOINTTHROW.
