- 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

- with tcc (extra small size):
-
- tiny_impdef luatex.dll
- tcc -shared -o runscript.dll runscript_dll.c luatex.def

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.
