Hi miskox,

simply use delayed expansion, that solves also problems with all other special characters.

However what puzzles me is why it even makes any difference if it comes before the caret (or after it, as this seems to work too). It forces the delayed expansion phase to trigger. The delayed expansion phase only have an effect, when at least one exclamation mark is in the line (and it must still ...

I have made the creation of the exclamation mark and caret a little shorter, which happens before the macro is created. Code: Select all FOR /F "tokens=1-3" %%! IN ("! ! ^ ^^^! . ^^^^") DO ^ It looks a little strange, but since the first caret disappears in delayed expansion, it can already be used...

Hi, nice to see progress here. However, I don't like your style of writing code. It's really unreadable, and the variable names are, at best, ugly. :D So I built it differently, independently of delayed expansion mode, but with a completely different solution. I only copy the text string once at the...

If you are using at least windows 10 you could use ssh. Laptop> ssh desktopuser@[DesktopName or DesktopIP] "Desk_Sleep.bat" But you have to enable the ssh server on the desktop Get started with OpenSSH for Windows . Then you need to create an ssh keypair on your laptop Generate new ssh keys in Windo...

Hi nnnmmm, i need a batch that returns a var ABC 2nd line is an empty line are there batch commands to get the 2nd string ABC? I suppose not, but you could solve it with a trick. Build one config file which contains only the "ABC". Then you can build the spec file before you start the compiler by ec...

And I learned a new variant for the trick last month, now it's enough to use %%" instead of %%~". FOR /F "tokens=* delims=X" %%^" in ("X") do ( echo %%" Special characters &..|..^..<..> echo %%" Event a closing bracket ) doesn't harm ) It's possible to create a single FOR meta-variable that's empty....

And now my own try of a progress bar. But with the use of 8 different steps per single character. It shows the progress bar in the window and in the title I'm using the unicode characters from U+2588 to U+258F. ▏ ▎ ▍ ▌ ▋ ▊ ▉ █ How it looks depends on the selected font. My best results are with a uni...

You can use a small function to exit only the current batch :exit-current-batch for /L %%# in (0 1 40) DO ( (goto) 2> NUL call set "_tmp=%%0" call set "_tmp=%%_tmp:~0,1%%" call set "_tmp=%%_tmp::=%%" if defined _tmp ( REM Current Batch entry found exit /b ) ) exit /b Just use CALL :exit-current-batc...

Is it possible to bypass the endlocal barrier/tunnel inside a call of variables that have LF or in any case the code to create multiline macros? Yes. You can even make it so that it's possible to return the macro to whatever mode it was in before. The :lineReturnTest test enables delayed expansion ...

Hi einstein1969, I don't see the relation between delayed expansion and line feeds here. Using of line feeds in macros just depends on code blocks. It is essential to use the parenthesis in the macro. rem define a line feed for using in macro definitions (Set $\n=^^^ %= this line is required =% ) se...

After reading Batch: How to Properly Use CHOICE Inside of CALL Function? The problem was probably a previously set of the errorlevel variable. I was curious whether it is possible to recognize this programmatically. "if defined variableName" doesn't work here, because it's true for pseudovariables, ...

Hi,

a bit nitpicking

new functions: :chr, :asc, :asciiMap (Fri Apr 01, 2011 10:34 pm)

I probably developed the ESC, DEL and CR (buffer overflow) technique, but the rest was just a copy and paste.

1) Undefined variables and an empty variable names behave differently (#5 and #6). Perhaps an empty variable name accesses some random existing variable :?: After some more testing, I found the behavior for an empty searchPath-variable name. If you use the expression "%%~$:X" or ""%%~$====:X" the n...

I would like to share some insights about the rarely used syntax of "%~$PATH:I" %~$PATH:I Searches the directories listed in the PATH environment variable and expands %I to the fully qualified name of the first directory found. If the environment variable name isn't defined or the file isn't found b...
