Suppose the following FOR-loop command, to be run from the command-line
(if using a batch file, double each percent '%' sign):
FOR %l IN ("a,b,c,d,e" "f,g,h,i,j") DO (
FOR /F "delims=, tokens=1-3*" %a IN (%l) DO @echo %a-%b-%c-%d
)
The outermost FOR-loop enumerates the two strings "a,b,c,d,e" and
"f,g,h,i,j" (placed in %l), and parse each of these in turn, splitting
them at each specified delimiter (here only one character) ',' and storing
the results in consecutive tokens %a, %b, %c, %d, with the last token %d
containing all the remaining string (non-split).
The expected result is:
a-b-c-d,e
f-g-h-i,j
However, due to the way the delimiters string specified by the "delims="
option is stored (no stack/heap duplication of the FOR-option substring,
but reading from it directly), during the first run of the innermost
FOR-loop, the option string "delims=, tokens=1-3*" was truncated to just
after the ',' due to the erroneous "delims=" parsing, so that when this
FOR-loop ran for a second time (to deal with the second string), the option
string was already erroneously truncated, without the "tokens=..." part,
so that the parsing results were not stored in the tokens and resulting in:
a-b-c-d,e
f-%b-%c-%d
instead. The solution is to save where the "delims=" string needs to be
cut, but wait until running the actual FOR-loop to terminate it (and
saving the original character too), run the FOR-loop body, and then
restore the original character where termination took place. This allows
having the FOR-loop option string valid for the next execution of the
FOR-loop.
CORE-13682
- Split SubstituteVars() into its main loop and a helper SubstituteVar()
that just substitutes only one variable.
- Use this new helper as the basis of the proper implementation of the
delayed expansion of variables.
- Fix a bug introduced in commit 495c82cc, when GetBatchVar() fails.
CORE-11857 CORE-13736
It will be followed with a separate fix for the FOR-loop code.
Fixes some cmd_winetests.
A NULL pointer can be returned for a valid existing batch/FOR variable,
in which case the enhanced-variable getter should return an empty string.
This situation can happen e.g. when forcing a FOR-loop to tokenize a
text line with not enough tokens in it.
- Add Chinese Traditional language support for CHARMAP_NEW, DRWTSN32, UTILMAN, CHKDSK.
- Improve translation for CLIPBRD, MSCONFIG(_NEW), NOTEPAD, SHUTDOWN, SNDREC32, WINHLP32, DISKPART, FORMAT, REGSVR32, RUNDLL32, USERINIT, DESK.CPL and TIMEDATE.CPL.
They are currently specified for documentation purposes (i.e. what
Windows 8+ CMD.EXE can report) but not used yet, since ReactOS does not
support them.
