- Script wrappers in TeX Live on Windows
-
- Rationale
-
- Wrappers enable use of scripts on Windows as regular programs.
- They are also required for some binary programs to set up the
- right environment for them.
-
- Batch scripts can be used for wrapping but they are not as universal
- as binaries (there are some odd cases where they don't work) and
- it is hard to make them robust and secure. Compiled binary wrappers
- don't suffer from these problems but they are harder to write, debug
- and maintain in comparison to scripts. For these reasons a hybrid
- approach is taken that combines a binary stub with a launcher script.
-
- Adding wrappers for user scripts
-
- The script wrapping machinery is not limited to scripts shipped with
- TeX Live. You can also use it for script programs from manually
- installed packages. This should minimize problems when using them
- with TeX Live.
-
- First, make sure that there is an interpreter program available on
- your system for the script you want to use. Interpreters for Perl
- and Lua are bundled with TeX Live, all others have to be installed
- independently. Lua scripts are the most efficient to run, so if you
- consider writing a new script, that would be the recommended choice.
-
- The following script types and their file extensions are currently
- supported and searched in that order:
-
- Lua (.tlu;.texlua;.lua) -- included
- Perl (.pl) -- included
- Ruby (.rb) -- requires installation
- Python (.py) -- requires installation
- Tcl (.tcl) -- requires installation
- Java (.jar) -- requires installation
- VBScript (.vbs) -- part of Windows
- JScript (.js) -- part of Windows
- Batch (.bat;.cmd) -- part of Windows
-
- Finally, Unix-style extensionless scripts are searched as last and
- the interpreter program is established based on the she-bang (#!)
- specification on the very first line of the script. This can be
- an arbitrary program but it must be present on the search path.
-
- Next, the script program needs to be installed somewhere below the
- 'scripts' directory under one of the TEXMF trees (consult the
- documentation or texmf/web2c/texmf.cnf file for a list). You may
- need to update the file search database afterwards with:
-
- mktexlsr [TEXMFDIR]
-
- It is also possible to use scripts that are outside of TEXMF hierarchy
- by adjusting TEXMFSCRIPTS environment or kpathsea variable, see
- kpathsea documentation for more information on setting its variables.
-
- Test if the script can be located with:
-
- kpsewhich --format=texmfscripts <script-name>.<ext>
-
- This should output the full path to the script if everything is
- properly installed and configured. If this test is successful,
- the script can be run immediately with:
-
- runscript <script-name> [script arguments]
-
- If you prefer to call the script program simply by its name, copy
- and rename bin/win32/runscript.exe (or bin/win64/runscript.exe for
- 64-bit Windows) to <script-name>.exe and put it somewhere on the
- search path.]]

-
- Wrapper structure
-
- Wrappers consist of small binary stubs and a common texlua script.
- The binary stubs are all the same, just different names (but CLI
- and GUI stubs differ, see below, and GUI stubs are actually all
- different due to different embedded icons).
-
- The job of the binary stub is twofold: (a) call the texlua launcher
- script 'runscript.tlu' from the same directory (or more precisely
- from the directory containing 'runscript.dll') and (b) pass to it
- argv[0] and the unparsed argument string as the last two arguments
- (after adding a sentinel argument, which ends with a new line
- character). Arbitrary C strings can be passed, because the script
- is executed by linking with luatex.dll and calling the lua
- interpreter internally rather than by spawning a new process.
-
- There are two flavours of the binary stub: one for CLI programs
- and another one for GUI programs. The GUI variant does not open
- a console window nor does it block the command prompt if started
- from there. It also uses a dialog box to display an error message
- in addition to outputting to stderr.
-
- The stubs are further split into a common DLL and EXE proxies
- to it. This is for maintenance reasons - updates can be done by
- replacement of a single DLL rather than all binary stubs.
-
- The launcher script knows, which variant has been used to invoke it
- based on the sentinel argument. The lack of this argument means
- that it was invoked in a standard way, i.e., through texlua.exe.
-
- All the hard work of locating a script/program to execute happens
- in the launcher script. The located script/program is always
- executed directly by spawning its interpreter (or binary) in a new
- process. The system shell (cmd.exe) is never called (except for
- batch scripts, of course). If the located script happens to be
- a (tex)lua script, it is loaded and called internally from within
- this script, i.e. no new process is spawned. Execution is done
- using a protected call, so any compile or runtime errors are catched.
-
- Source files
-
- runscript.tlu launcher script for locating and dispatching
- target scripts/programs
- runscript_dll.c common DLL part of the binary stubs; locates and
- calls the launcher script
- runscript_exe.c EXE proxy to the common DLL for CLI mode stubs
- wrunscript_exe.c EXE proxy to the common DLL for GUI mode stubs
-
- Compilation of binaries (requires luatex.dll in the same directory)
-
- with gcc (size optimized):
-
- gcc -Os -s -shared -o runscript.dll runscript_dll.c -L./ -lluatex
- gcc -Os -s -o runscript.exe runscript_exe.c -L./ -lrunscript
- gcc -mwindows -Os -s -o wrunscript.exe wrunscript_exe.c -L./ -lrunscript

+
+ Script wrappers in TeX Live on Windows
+
+ Rationale
+
+ Wrappers enable use of scripts on Windows as regular programs.
+ They are also required for some binary programs to set up the
+ right environment for them.
+
+ Batch scripts can be used for wrapping but they are not as universal
+ as binaries (there are some odd cases where they don't work) and
+ it is hard to make them robust and secure. Compiled binary wrappers
+ don't suffer from these problems but they are harder to write, debug
+ and maintain in comparison to scripts. For these reasons a hybrid
+ approach is taken that combines a binary stub with a launcher script.
+
+ Adding wrappers for user scripts
+
+ The script wrapping machinery is not limited to scripts shipped with
+ TeX Live. You can also use it for script programs from manually
+ installed packages. This should minimize problems when using them
+ with TeX Live.
+
+ First, make sure that there is an interpreter program available on
+ your system for the script you want to use. Interpreters for Perl
+ and Lua are bundled with TeX Live, all others have to be installed
+ independently. Lua scripts are the most efficient to run, so if you
+ consider writing a new script, that would be the recommended choice.
+
+ The following script types and their file extensions are currently
+ supported and searched in that order:
+
+ Lua (.tlu;.texlua;.lua) -- included
+ Perl (.pl) -- included
+ Ruby (.rb) -- requires installation
+ Python (.py) -- requires installation
+ Tcl (.tcl) -- requires installation
+ Java (.jar) -- requires installation
+ VBScript (.vbs) -- part of Windows
+ JScript (.js) -- part of Windows
+ Batch (.bat;.cmd) -- part of Windows
+
+ Finally, Unix-style extensionless scripts are searched as last and
+ the interpreter program is established based on the she-bang (#!)
+ specification on the very first line of the script. This can be
+ an arbitrary program but it must be present on the search path.
+
+ Next, the script program needs to be installed somewhere below the
+ 'scripts' directory under one of the TEXMF trees (consult the
+ documentation or texmf/web2c/texmf.cnf file for a list). You may
+ need to update the file search database afterwards with:
+
+ mktexlsr [TEXMFDIR]
+
+ It is also possible to use scripts that are outside of TEXMF hierarchy
+ by adjusting TEXMFSCRIPTS environment or kpathsea variable, see
+ kpathsea documentation for more information on setting its variables.
+
+ Test if the script can be located with:
+
+ kpsewhich --format=texmfscripts <script-name>.<ext>
+
+ This should output the full path to the script if everything is
+ properly installed and configured. If this test is successful,
+ the script can be run immediately with:
+
+ runscript <script-name> [script arguments]
+
+ If you prefer to call the script program simply by its name, copy
+ and rename bin/win32/runscript.exe (or bin/win64/runscript.exe for
+ 64-bit Windows) to <script-name>.exe and put it somewhere on the
+ search path.]]
+
+local docstr = [[
+
+ Wrapper structure
+
+ Wrappers consist of small binary stubs and a common texlua script.
+ The binary stubs are all the same, just different names (but CLI
+ and GUI stubs differ, see below, and GUI stubs are actually all
+ different due to different embedded icons).
+
+ The job of the binary stub is twofold: (a) call the texlua launcher
+ script 'runscript.tlu' from the same directory (or more precisely
+ from the directory containing 'runscript.dll') and (b) pass to it
+ argv[0] and the unparsed argument string as the last two arguments
+ (after adding a sentinel argument, which ends with a new line
+ character). Arbitrary C strings can be passed, because the script
+ is executed by linking with luatex.dll and calling the lua
+ interpreter internally rather than by spawning a new process.
+
+ There are two flavours of the binary stub: one for CLI programs
+ and another one for GUI programs. The GUI variant does not open
+ a console window nor does it block the command prompt if started
+ from there. It also uses a dialog box to display an error message
+ in addition to outputting to stderr.
+
+ The stubs are further split into a common DLL and EXE proxies
+ to it. This is for maintenance reasons - updates can be done by
+ replacement of a single DLL rather than all binary stubs.
+
+ The launcher script knows, which variant has been used to invoke it
+ based on the sentinel argument. The lack of this argument means
+ that it was invoked in a standard way, i.e., through texlua.exe.
+
+ All the hard work of locating a script/program to execute happens
+ in the launcher script. The located script/program is always
+ executed directly by spawning its interpreter (or binary) in a new
+ process. The system shell (cmd.exe) is never called (except for
+ batch scripts, of course). If the located script happens to be
+ a (tex)lua script, it is loaded and called internally from within
+ this script, i.e. no new process is spawned. Execution is done
+ using a protected call, so any compile or runtime errors are catched.
+
+ Source files
+
+ runscript.tlu launcher script for locating and dispatching
+ target scripts/programs
+ runscript_dll.c common DLL part of the binary stubs; locates and
+ calls the launcher script
+ runscript_exe.c EXE proxy to the common DLL for CLI mode stubs
+ wrunscript_exe.c EXE proxy to the common DLL for GUI mode stubs
+
+ Compilation of binaries (requires luatex.dll in the same directory)
+
+ with gcc (size optimized):
+
+ gcc -Os -s -shared -o runscript.dll runscript_dll.c -L./ -lluatex
+ gcc -Os -s -o runscript.exe runscript_exe.c -L./ -lrunscript
+ gcc -mwindows -Os -s -o wrunscript.exe wrunscript_exe.c -L./ -lrunscript
+
+ with tcc (extra small size):
+
+ tiny_impdef luatex.dll
+ tcc -shared -o runscript.dll runscript_dll.c luatex.def
+ tcc -o runscript.exe runscript_exe.c runscript.def
