Hello Akira,

you mention possibility of --shell-escape at http://tug.org/pipermail/luatex/2017-March/006410.html.

How exactly do you mean to combine "ffi" and "--shell-escape" to work with latest ConTeXt/LuaTeX?

(I tried (rather amateurishly) to run "context --shell-escape WinTest.mkiv" - but it didn't help.)

context doesn't use --shell-escape (control over executables happens via the sandbox mechanism)

BTW:

WinCon.dll contains some functions to print COLORED text to the console screen and enables some basic WinAPI functions (like capturing window bitmap) to Lua; I've been using especially colored printing in combination with ConTeXt ("warnings" in magenta, "errors" in red...).

local ansicolor = { r = function(s) return "" .. s .."" end, g = function(s) return "" .. s .."" end, b = function(s) return "" .. s .."" end, c = function(s) return "" .. s .."" end, m = function(s) return "" .. s .."" end, y = function(s) return "" .. s .."" end } local formatters = string.formatters utilities.strings.formatters.add(formatters, "cr", [[cr(%s)]], { cr = ansicolor.r }) utilities.strings.formatters.add(formatters, "cg", [[cg(%s)]], { cg = ansicolor.g }) utilities.strings.formatters.add(formatters, "cb", [[cb(%s)]], { cb = ansicolor.b }) utilities.strings.formatters.add(formatters, "cc", [[cc(%s)]], { cc = ansicolor.c }) utilities.strings.formatters.add(formatters, "cm", [[cm(%s)]], { cm = ansicolor.m }) utilities.strings.formatters.add(formatters, "cy", [[cy(%s)]], { cy = ansicolor.y }) print(ansicolor.r("red")) print(ansicolor.g("green")) print(ansicolor.b("blue")) print(ansicolor.c("cyan")) print(ansicolor.m("magenta")) print(ansicolor.y("yellow")) logs.writer(formatters["this is in %!cr! or %!cg! or %!cb! or %s"]("red","green","blue","oeps")) logs.report("whatever","this is in %!cr! or %!cg! or %!cb! or %s","red","green","blue","oeps") (you can also use mtxrun --ansi ....)

Any way to re-enable user DLL loading into ConTeXt, even in the future, would be appreciated...

Best regards,

Lukas

I encountered problem loading WinCon.dll (a module that I wrote and I've been using for several years)

In the new lua(jit)tex, one cannot use DLL modules. See my mail in http://tug.org/pipermail/luatex/2017-March/006410.html http://tug.org/pipermail/luatex/2017-March/006413.html

Reason: I could not build usable binaries for the new sources by linking dynamically lua-5.2.4 or luajit. Thus I changed to link lua-5.2.4 etc. statically.

Best, Akira
