****Lean Undroidwish Construction Kit**** A by-product of [undroidwish], see it in action in http://www.ch-werner.de/LUCK.html, the available binary templates in http://www.ch-werner.de/LUCK, and the source code in https://www.androwish.org/home/dir?ci=tip&name=undroid/luck. !!!!!! [undroidwish_image] !!!!!! Web based (CGI) script to make a taylored undroidwish, vanillawish or vanillatclsh from binaries which are searched in the same directory as the tclsh or wish executing this script. Additionally, prefabricated configurations are presented. These are searched like the binaries and additionally relative to the parent directory of this script. In the first step, the user selects a prefabricated or uploaded configuration or a binary. In the second step, a selection of packages derived from the binary's ZIP is presented plus some other options such as ZIP password and output filename. The package selection and other options can be primed by the info from a prefabricated or uploaded configuration. In the last step the user can generate a new binary and configuration with only the selected packages and other options, which is downloaded as a file. The generation process uses [memchan] channels and ZIP mounts of memory buffers, i.e. no native filesystem for temporary storage is required. ****Currently supported/available platforms**** The following table is a snapshot from 2022-02-11. %|Platform|Machine|Remarks|% &|FreeBSD|x86||& &|Haiku|x86, x86_64|undroidwish only|& &|Illumos|x86||& &|Linux|x86, x86_64, arm, aarch64|glibc and musl, wayland|& &|MacOSX|x86_64|no builds for Catalina and newer|& &|OpenBSD|x86_64||& &|Windows|x86, x86_64||& ****REST interface**** The CGI script is RESTful and can be used as a service from other Tcl scripts utilizing tcllib's rest package, e.g. to easily mass produce Tcl apps for a variety of platforms. Here is an example on how to read out information and make a binary: ====== # Demonstrate usage of LUCK RESTfully, requires a locally running LUCK service on port 8015 package require rest set luck(list) { url http://localhost:8015/cgi-bin/luck.tcl description {list of available templates} result raw method post static_args {api list} req_args {} opt_args {} } # req_args: # -template name of binary template, e.g. vanillawish-linux32 # opt_args: # -withtips when present send alternating lines of extension name and description set luck(extlist) { url http://localhost:8015/cgi-bin/luck.tcl description {list of extensions of given template} result raw method post static_args {api extlist} req_args {template:} opt_args {withtips} } # req_args: # -template name of binary template, e.g. vanillawish-linux32 # -include list of extensions to be embedded # opt_args: # -appfile *.tcl (for app/main.tcl) or *.zip (must have main.tcl), # content must be base64 encoded # -cmdline (undroidwish) additional startup arguments # -appicon (undroidwish) BMP (24 bit RGB) icon, # content must be base64 encoded # -winicon (Windows binaries) icon (*.ico) for executable, # content must be base64 encoded # -passwd ZIP password set luck(generate) { url http://localhost:8015/cgi-bin/luck.tcl description {generate a binary} result raw method post static_args {api generate} req_args {template: include: appfile:} opt_args {cmdline: appicon: winicon: passwd:} } # create REST interface rest::create_interface luck # list templates puts "==== Templates ====" puts -nonewline [luck::list] # list extensions of vanillawish-win32.exe puts "==== Extensions of vanillawish-win32.exe ====" puts -nonewline [luck::extlist -template vanillawish-win32.exe] # make tkbugz for win32 from a ZIP which contains main.tcl # with the single line "source [info nameofexecutable]/tkbugz/tk_bugz.tcl" set main_tcl_zip { UEsDBBQAAAAIAJVmp1I2IJT8MAAAADIAAAAIABwAbWFpbi50Y2xVVAkAA/oblWAL HJVgdXgLAAEE6AMAAAToAwAAK84vLUpOVYjOzEvLV8hLzE3NT0utSE0uLUlMykmN 1S/JTipNrwJS8SBaryQ5hwsAUEsBAh4DFAAAAAgAlWanUjYglPwwAAAAMgAAAAgA GAAAAAAAAQAAAKSBAAAAAG1haW4udGNsVVQFAAP6G5VgdXgLAAEE6AMAAAToAwAA UEsFBgAAAAABAAEATgAAAHIAAAAAAA== } set f [open tkbugz.exe wb] puts -nonewline $f \ [luck::generate -template vanillawish-win32.exe \ -include tkbugz -appfile $main_tcl_zip] close $f ====== Most vanillatclsh-en from the web site contain a REST based TUI ([CUI]) frontend called `lucktui` which is available in the luck package, e.g. by running `vanillatclsh... builtin:luck/lucktui.tcl` or `vanillatclsh... builtin:lucktui` for short. Here's a sample session as an https://asciinema.org/a/gNg7QznCHEql74SPLo9mcPSst%|%ASCII screencast%|%. ****How to roll your own build service**** * fetch the relevant (or all) binary templates from http://www.ch-werner.de/LUCK * store these in one directory * execute `vanillawish... builtin:LUCK` with a vanillawish runnable on your platform; this starts a local [tclhttpd] on port 8015 and tries to invoke a web browser on its LUCK page * or execute `vanillatclsh... builtin:lucktui` with a vanillatclsh runnable on your platform; this presents the TUI with a local [tclhttpd] on port 8015 * begin mass production of single file self contained Tcl/Tk apps; the world is your oyster! ****Build service (advanced)**** * thanks to [tclvfs] and [SQLite], the above mentioned binaries can be wrapped up, compressed, and deduplicated into a virtual filesystem based on a [SQLite] database * this shrinks the required disk space down from 900 MByte to about 300 MByte * the current database is in http://www.ch-werner.de/LUCK/luck.tdd * the source code of the VFS module is in https://www.androwish.org/home/file?name=undroid/luck/cgi-bin/luckvfs.tcl&ci=tip * if `luck.tdd` is placed in the same directory as the CGI script `luck.tcl` it is preferred over the (undroidwish|vanilla(tclsh|wish)) binaries serving all alternatives contained in the database * (experimental) when using `luck.tdd` and the prefabricated configuration `luck.cfg` a big fat binary can be produced which serves as the CGI program and has that database integrated * (experimental, self referential) when using a big fat binary and the prefabricated configuration `luck.cfg` another big fat binary for another platform can be produced ---- ****LUCK(y) success story: with light speed to slow trains**** The LUCKy steps to a train application: Try it, it is fun! 1. Open the [trains3.tcl] wiki page , section "Code" 2. Copy the Code snippet in the "Code" box by pressing the small right icon on the upper-right corner of the big grey code box. 3. Go to the LUCK(y) page: http://www.ch-werner.de/LUCK.html 4. Select a *vanillawish* suitable for your platform, for example "vanillawish-win32.exe". 5. Scroll down to the entry box titled "Application app/main.tcl" and paste the code snippet (Press Ctrl/Apple+v) 6. Press button "generate binary". The binary is downloaded. Start the binary and enjoy the movie. ---- '''[aplsimple] - 2022-04-02 06:35:27''' Thank you, Christian, for your smart interface to construct stand-alone executables, including vanilla tclsh and wish by themselves. I wonder why this work is so poorly announced and promoted. LUCK is one of Tcl/Tk gems that deserves to be included in the wiki's start page, side by side with Tcl Developer Xchange link. [APN] I agree along with Paul's [BAWT] and Roy's build farm. I've tweeted a couple of times on all these but that's ephemeral, they should be somewhere front and center as development resources. <>SDL|AndroWish|Windows|Distribution
