@REM Change the value of nextshell to one of the supported types, and add code within payload sections for tcl,sh,bash,powershell as appropriate.
@REM This wrapper can be edited manually (carefully!) - or bash,tcl,perl,powershell scripts can be wrapped using the Tcl-based punkshell system
@REM e.g from within a running punkshell: dev scriptwrap.multishell <inputfilepath> -outputfolder <folderpath>
@REM Call with sh, bash, perl, or tclsh. (powershell untested on unix)
@REM Due to lack of shebang (#! line) Unix-like systems will hopefully default to a flavour of sh that can divert to bash if the script is called without an interpreter - but it may depend on the shell in use when called.
@REM If you find yourself really wanting/needing to add a shebang line - do so on the basis that the script will exist on unix-like systems only.
@REM in batch scripts - array syntax with square brackets is a simulation of arrays or associative arrays.
@REM note that many shells linked as sh do not support substition syntax and may fail - e.g dash etc - generally bash should be used in this context
@SET "validshelltypes= pwsh____________ powershell______ sh______________ wslbash_________ bash____________ tcl_____________ perl____________ none____________"
@REM for batch - only win32 is relevant - but other scripts on other platforms also parse the nextshell block to determine next shell to launch
@REM nextshellpath and nextshelltype indices (underscore-padded to 16wide) are "other" plus those returned by Tcl platform pkg e.g win32,linux,freebsd,macosx
@REM The horrible underscore-padded fixed-widths are to keep the batch labels aligned whilst allowing values to be set
@REM If more than 64 chars needed for a target, it can still be done but overall script padding may need checking/adjusting
@REM Supporting more explicit oses than those listed may also require script padding adjustment

@REM -- cmd/batch file section (ignored on unix but should be left in place)
@REM -- This section intended mainly to launch the next shell (and to escalate privileges if necessary)
@REM -- Avoid customising this if you are not familiar with batch scripting. cmd/batch script can be useful, but is probably the least expressive language and most error prone.
@REM -- For example - as this file needs to use unix-style lf line-endings - the label scanner is susceptible to the 512Byte boundary issue: https://www.dostips.com/forum/viewtopic.php?t=8988#p58888
@REM -- This label issue can be triggered/abused in files with crlf line endings too - but it is less likely to happen accidentaly.
@REm -- See also: https://stackoverflow.com/questions/4094699/how-does-the-windows-command-interpreter-cmd-exe-parse-scripts/4095133#4095133
@REM ############################################################################################################################
@REM -- Due to this issue -seemingly trivial edits of the batch file section can break the script! (for Windows anyway)
@REM -- Even something as simple as adding or removing an @REM
@REM -- From within punkshell - use:
@REM -- deck scriptwrap.checkfile filepath
@REM -- to check your templates or final wrapped scripts for byte boundary issues
@REM -- It will report any labels that are on boundaries
@REM -- This is why the nextshell value above is a 2 digit key instead of a string - so that editing the value doesn't change the byte offsets.
@REM -- Editing your sh,bash,tcl,pwsh payloads is much less likely to cause an issue. There is the possibility of the final batch :exit_multishell label spanning a boundary - so testing using deck scriptwrap.checkfile is still recommended.
@REM -- Alternatively, as you should do anyway - test the final script on windows
@REM -- Aside from adding comments/whitespace to tweak the location of labels - you can try duplicating the label (e.g just add the label on a line above) but this is not guaranteed to work in all situations.
@REM -- '@REM' is a safer comment mechanism than a leading colon - which is used sparingly here.
@REM -- A colon anywhere in the script that happens to land on a 512 Byte boundary (from file start or from a callsite) could be misinterpreted as a label
@REM -- It is unknown what versions of cmd interpreters behave this way - and deck scriptwrap.checkfile doesn't check all such boundaries.
@REM -- For this reason, batch labels should be chosen to be relatively unlikely to collide with other strings in the file, and simple names such as :exit or :end should probably be avoided

#e.g "c:/windows/system32/" is quite likely in the path ahead of msys,git etc.
#e.g It means a /usr/bin/env bash call may launch the (linux elf) bash for wsl rather than the msys bash
