Hello, I just renewed ConTeXt and new error when using "require" appears (it worked OK until the update): ---- t-Req.mkiv \startluacode require "Test-U" \stopluacode \starttext A \stoptext ---- " mtx-context | run 1: luatex --fmt="c:/ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/cont-en" --interaction="nonstopmode" --jobname="t-Req" --lua="c:/ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/cont-en.lui" --no-parse-first-line --c:FILE="t-Req.mkiv" --c:currentrun=1 --c:fulljobname="C:/Lukas/ConTeXt/Test/t-Req.mkiv" --c:halt-on-error --c:input="C:/Lukas/ConTeXt/Test/t-Req.mkiv" --c:kindofrun=1 --c:mode="t-Req" --c:nonstopm ode "cont-yes.mkiv" This is LuaTeX, Version beta-0.70.2-2012092822 (TeX Live 2012/W32TeX) \write18 enabled.

You can best set that in a local texmfcnf.lua file. In that case you use the original definition of luainputs and append lua_path to it. That way script in the context tree can also be found.

OK... I'm not familiar with (Lua)TeX deeply enough to know how exactly to do it, so a couple a questions: - Where to put (my personal) texmfcnf.lua? The intention is Ctx to find and load its original texmfcnf.lua and then to load my texmfcnf.lua which would modify only some elements (namely: the LUAINPUTS member). I'd like to keep "factory" texmfcnf.lua settings as much as possible. - When I look into "c:\ConTeXt\tex\texmf\web2c\texmfcnf.lua", I see many paths: - beginning with "!!", - ending with "//". What does mean this convention? - I found 2 config files: c:\ConTeXt\tex\texmf\web2c\texmf.cnf c:\ConTeXt\tex\texmf\web2c\texmfcnf.lua It seems that the latter is a "Luaed" form of the former. How are used both files? Is the latter built from the former or vice versa? Or the former is no more used and I'm having it among Ctx files by chance? (Or a link to a place where to learn more would be appreciated.) TIA. Best regards, Lukas

this controls the filedatabase building and recurssion into subtrees

c:\ConTeXt\tex\texmf\web2c\texmf.cnf c:\ConTeXt\tex\texmf\web2c\texmfcnf.lua

a bit more than that as we can have directives and such (and even have path tables)

only the lua file is used

no, for texlive the latter is adapted a bit (few lines) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Hello, my "trick" with LUAINPUTS system variable stopped working after the today's Ctx update. So I'm trying again to solve the problem that ---- \startluacode require "LPr-U" \stopluacode ---- doesn't load the file at "d:/Lukas/Lua/LPr-U.lua". On Mon, 15 Oct 2012 20:29:53 +0200, Hans Hagen wrote:

Following Hans' advice, I created "d:/texmf-local/web2c/contextcnf.lua" with the following content: ---- return { LUAINPUTS = "d:/Lukas/Lua/", } ---- but I'm still getting error with "require". What other steps do I have to do to make it work? TIA. Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

So - ?

no clue ... maybe an error in test.lua

.... Have you seen the content of "Test.lua"? It just prints some text...

When I downgraded Ctx to the previous installed version, it works...

When I make e:\tmp\whatever.lua (current path) e:\tmp\whatever\something.lua And run \starttext \enabletrackers[resolvers.libraries] \startluacode print("LUAINPUTS",os.getenv("LUAINPUTS")) require("whatever") ; require("something") ; \stopluacode \stoptext i get LUAINPUTS e:/tmp/whatever resolvers > libraries > ! locating "whatever" as "whatever.lua" using formats "texlua" resolvers > libraries > ! checking for "whatever.lua"' using format "tex" resolvers > libraries > ! lib "whatever.lua" located on "whatever.lua" whatever resolvers > libraries > ! locating "something" as "something.lua" using formats "texlua" resolvers > libraries > ! checking for "something.lua"' using format "tex" resolvers > libraries > ! checking for "something.lua"' using format "lua" resolvers > libraries > ! lib "something.lua" located on "e:/tmp/whatever/something.lua" something so it must be something with your path spec ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Hello,

...

When I make

e:\tmp\whatever.lua (current path) e:\tmp\whatever\something.lua

And run

\starttext

\enabletrackers[resolvers.libraries]

\startluacode print("LUAINPUTS",os.getenv("LUAINPUTS"))

require("whatever") ; require("something") ; \stopluacode

\stoptext

i get

LUAINPUTS e:/tmp/whatever resolvers > libraries > ! locating "whatever" as "whatever.lua" using formats "texlua" resolvers > libraries > ! checking for "whatever.lua"' using format "tex" resolvers > libraries > ! lib "whatever.lua" located on "whatever.lua" whatever resolvers > libraries > ! locating "something" as "something.lua" using formats "texlua" resolvers > libraries > ! checking for "something.lua"' using format "tex" resolvers > libraries > ! checking for "something.lua"' using format "lua" resolvers > libraries > ! lib "something.lua" located on "e:/tmp/whatever/something.lua" something

so it must be something with your path spec

it seems that I solved the problem finally. Normally, the LUA_PATH contains members like "D:\Lukas\Lua\?.lua", whilst LUAINPUTS has form of "e:/tmp/whatever", so there are three differences: 1) drive letter is upper-case in my case, lower case in Hans' one, 2) I'm using backslashes '\' in path description, Hans uses '/', 3) my LUAINPUTS path contains "?.lua" and "?.clua" strings, which are typical for pure Lua scripts with LUA_PATH (and "?.dll" with LUA_CPATH), whilst Hans' LUAINPUTS doesn't contain these strings. So I started to check influence of these three differences... It seems that #3 is fatal - "?.[c]lua" must not be a part of the path; although it's been working so far. So - if anyone interested - I modified slightly my Ctx-initializing batch '_InitCtx.bat': ---- set PATH=c:\ConTeXt\tex\texmf-mswin\bin;%PATH% :: The lowercase "c:" if fatally necesssary! set LUAINPUTS=%LUAINPUTS%;%LUA_PATH% :: >= 10/2012 set LUAINPUTS=%LUAINPUTS:?.luac=% set LUAINPUTS=%LUAINPUTS:?.lua=% :: >= 24.10.2012 ---- It seems also that Ctx accepts both "a/b/c" and "a/b/c/" forms of LUAINPUTS members, i.e. with or without the trailing (back)slash. Thanks, Hans, for your detailed testing - the signal "LUAINPUTS e:/tmp/whatever" directed me to the solution. Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

should be ok

should work out ok too, windows internally accepts both but in the end context normalizes to / (i always use / anyway as that works on all platforma)

indeed, as LUAINPUTS is a path specification cf web2c/tds

yes, quite some some cleanup happens deep down Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Personally - I've been using "require <file-name>" so far at many places and there was no problem with it.

try with

btw, you should adapt LUAINPUTS and not some other environment variable

OK, so what does it mean practically? Should I define a new system variable LUAINPUTS to have similar content as LUA_PATH and LUA_CPATH are having? Or LUAINPUTS is a (Con|Lua)TeX(t) internal variable and should be modified another way? Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.
