If the link exists, the link is removed first, then a new link is created.

  • Make symbolic link

    CALL MakeLink :MakeSymboliclink  "path-of-sym-link"  "path-to-target-file"

  • Make hard link

    CALL MakeLink :MakeHardlink  "path-of-hard-link"  "path-to-target-file"

  • Make junction

    CALL MakeLink :MakeJunction  "path-of-junction"  "path-to-target-directory"

add-path.ps1 : append path to the PATH environment variable.

  • Add the current directory to the user's PATH

    add-path.ps1

  • Add the current directory to the system PATH

  3. Added the path to wtd.exe into the PATH environment variable.

  • Start Windows Terminal in the current directory

    In the Windows explorer, press Alt-d, input wtd, then Enter.

SetVcEnv.cmd : setup environment for Visual Studio tool chain.

  • Show help

    SetVcEnv /?

  • Provided environment variables

    VC_VER_FULL     e.g., 193431935
VC_VER_STD      e.g., 1934
VC_VER_MAJOR    e.g., 19
VC_VER_MINOR    e.g.,   34
VC_VER_BUILD    e.g.,     31935
VC_VER_STRING   e.g., 19.34.31935

OS_CAPTION      e.g., Microsoft Windows 10
OS_ARCH         e.g., 64-bit
OS_VER          e.g., 10.0.19045
OS_BUILD        e.g., 19045

Envvar.cmd: manipulate environment variables.

Mechanisms

See higher-level function invocation for Windows batch script.

Value functions

  • ValueEcho

    Echo a value.

  • ValueEq

    Test the equality of two values.

    SET A=xxx
SET B=xxx
CALL Envvar :ValueEq  "%%A%%"  "%%B%%"

    Then ERRORLEVEL becomes 1.

  • ValueFind

    Find a substring in a value.

  • ValueTokenize

    Tokenize a value, and process each token.

Envvar functions

  • EnvvarEcho

    Echo the value of an environment variable.

  • EnvvarIs

    Check the value of an environment variable.

    SET A=xxx
SET B=xxx
CALL Envvar :EnvvarIs  "B"  "%%A%%"

    Then ERRORLEVEL becomes 1.

  • EnvvarFind

    Find a substring in an environment variable.

  • EnvvarClear

    Undefine an environment variable.

  • EnvvarSet

    Set the value of an environment variable.

    SET A=0123
CALL Envvar :EnvvarSet  "B"  "%%A:~0,-1%%"

    Then the value of B becomes 012.

  • EnvvarCopy

    Set the value of an environment variable to another.

    SET A=xxx
CALL Envvar :EnvvarCopy  "A"  "B"

    Then the value of B becomes xxx.

  • EnvvarPrepend

    Prepend a string to the value of an environment variable.

  • EnvvarAppend

    Append a string to the value of an environment variable.

  • EnvvarTokenize

    Tokenize an environment variable, and process each token.

  • EnvvarPathPrepend

    Prepend a path to an environment variable.

    SET INCLUDE=C:\MyLib\include
CALL Envvar :EnvvarPathPrepend  "INCLUDE"  "C:\Lua-5.4\include"

    Then the value of INCLUDE becomes C:\Lua-5.4\include;C:\MyLib\include.

  • EnvvarPathAppend

    Append a path to an environment variable.

    SET INCLUDE=C:\Lua-5.4\include;C:\MyLib\include
CALL Envvar :EnvvarPathAppend  "INCLUDE"  "C:\Python-3.11\include"

    Then the value of INCLUDE becomes C:\Lua-5.4\include;C:\MyLib\include;C:\Python-3.11\include.

  • EnvvarPathRemove

    Remove a path from an environment variable.

    SET INCLUDE=C:\Lua-5.4\include;C:\MyLib\include;C:\Python-3.11\include
CALL Envvar :EnvvarPathRemove  "INCLUDE"  "C:\MyLib\include"

    Then the value of INCLUDE becomes C:\Lua-5.4\include;C:\Python-3.11\include.

  • EnvvarPathWin

    Use Windows path separator (a.k.a. backslash).
    The trailing backslash is also removed.

    CALL Envvar :EnvvarPathWin  "PUB"  "C:/pub/bin/"

    Then the value of PUB becomes C:\pub\bin.

  • EnvvarPathNix

    Use Unix/Linux path separator (a.k.a. slash).
    The trailing slash is also removed.

    CALL Envvar :EnvvarPathNix  "PUB"  "C:\pub\bin\"

    Then the value of PUB becomes C:/pub/bin.
