Dear ConTeXt folks, the filter module installed using $ ./first-setup.sh --extras="t-filter" does not work with the following example, which is also attached. \usemodule[filter] \defineexternalfilter[rest][filtercommand={pandoc -f rst -t context -o \externalfilteroutputfile\space \externalfilterinputfile}] \starttext There should be a table here. \startrest ========= ========= test table ========= ========= α b c d ======== ======== \stoprest \stoptext The output file `minimal-temp-rest.tex` is just empty. Replacing »α« by »a« solves the problem. Running `filtercommand` in a terminal produces the *correct* output though and no empty file. Is that a known problem? I also include a patch adding this example into `tests/` in [1]. Thanks, Paul [1] https://github.com/adityam/filter

Dear ConTeXt folks,

the filter module installed using

$ ./first-setup.sh --extras="t-filter"

does not work with the following example, which is also attached.

\usemodule[filter] \defineexternalfilter[rest][filtercommand={pandoc -f rst -t context -o \externalfilteroutputfile\space \externalfilterinputfile}] \starttext There should be a table here. \startrest ========= ========= test table ========= ========= α b c d ======== ======== \stoprest \stoptext

The output file `minimal-temp-rest.tex` is just empty.

Replacing »α« by »a« solves the problem.

Weird.

Is that a known problem?

No. The content of the file should not affect whether the filter is run or not. Can you add \traceexternalfilters on the top and check the output (look for lines starting with t-filter).

...

I also include a patch adding this example into `tests/` in [1].

Thanks. I added it to the test suite. The file works correctly on my machine. Which version of pandoc are you using? Does the error also occur if you use the dev branch from github? $git checkout dev $context tests/rest Aditya

I really have no idea why this is happening. Pandoc does not give too many debugging options. A couple of things to check: - What happens is you use pandoc -f rst -t native? (The updated example on github)? - If that fails, then try a simple rst file with a unicode letter (no table)? - If that also fails, then a simple markdown file with a unicode letter. - If that also fails, then some other program that reads a file and writes its contents to another file. - Manually execute the shell command from inside ConTeXt using \ctxlua{os.execute("....")}. Also, what OS you are on?

Since the .tex file is created, it means that the filter module is running correctly. It is calling pandoc with the right options, and pandoc is creating an empty rest-temp-rest.tex file. Now I have no idea why that file is empty. IIRC, pandoc sometimes misbehaves due to locale settings (but I don't see why locale should be different when a program is run from inside context then when it is run from a shell). I am stymied.

The output file is still empty. $ pandoc -f rst -t native -o rest-temp-rest.tex rest-temp-rest.tmp $ more rest-temp-rest.t{mp,ex} :::::::::::::: rest-temp-rest.tmp :::::::::::::: α :::::::::::::: rest-temp-rest.tex :::::::::::::: Pandoc (Meta {docTitle = [], docAuthors = [], docDate = []}) [ Para [Str "\945"] ] $ Is the α also encoded by `Str "\945"` in your setup?

- If that also fails, then a simple markdown file with a unicode letter.

That fails too. $ more rest-temp-rest.tex $ pandoc -f markdown -t native -o rest-temp-rest.tex rest-temp-rest.tmp $ more rest-temp-rest.t{mp,ex} :::::::::::::: rest-temp-rest.tmp :::::::::::::: α :::::::::::::: rest-temp-rest.tex :::::::::::::: Pandoc (Meta {docTitle = [], docAuthors = [], docDate = []}) [ Para [Str "\945"] ] $

...

- If that also fails, then some other program that reads a file and writes its contents to another file.

Usinng the following \defineexternalfilter [rest] [filter={cat \externalfilterinputfile\space | tee \externalfilteroutputfile}] works. $ more rest-temp-rest.t{mp,ex} :::::::::::::: rest-temp-rest.tmp :::::::::::::: α :::::::::::::: rest-temp-rest.tex :::::::::::::: α

...

- Manually execute the shell command from inside ConTeXt using \ctxlua{os.execute("....")}.

This does not work either. $ more tests/rest.tex % LM does not appear to have Greek letters in unicode slots \setupbodyfont[times] \starttext Start. \ctxlua{os.execute("pandoc -f rst -t context -o rest-temp-rest.tex rest-temp-rest.tmp")} \stoptext $ context tests/rest.tex $ more rest-temp-rest.t{mp,ex} :::::::::::::: rest-temp-rest.tmp :::::::::::::: α :::::::::::::: rest-temp-rest.tex :::::::::::::: $

Well, I would say to not waste your time any longer and to suspect Pandoc at fault here. If a newer Pandoc version is available in the Debian archive I can retest to check the Pandoc version as the possible culprit.

Taco can surely better explain why. I think somewhere in the luatex manual, he explains why luatex sets locale to "C". To see the differences in the environment, just do "set >/tmp/set-shell" and run context on: --8<---------------cut here---------------start------------->8--- \starttext \ctxlua{os.execute"set >/tmp/set-context"} \stoptext --8<---------------cut here---------------end--------------->8--- I don't have pandoc, but I'm sure that you can reproduce the problem with "LANG=C pandoc ..."

How can I use math-mode in such a table? Using $a_b$ it just prints $a_b$ instead of identifying this as a math-input.

I'm using pandoc 1.8.1.1 and context 2011.06.19.

Can you give a complete minimal example?

Maybe this could be helpful: http://hackage.haskell.org/packages/archive/pandoc/1.8.1.1/doc/html/src/Text... Does someone know what all this means? I guess especially interesting are the following lines: inlineToConTeXt (Math InlineMath str) = return $ char '$' <> text str <> char '$' inlineToConTeXt (Math DisplayMath str) = return $ text "\\startformula " <> text str <> text " \\stopformula"

It seems that pandoc's rst reader does not handle inline mathematics (at least with pandoc 1.6; I don't know if Pandoc 1.8 fixes this). $echo "\$a_b\$" | pandoc -f rst -t native Pandoc (Meta {docTitle = [], docAuthors = [], docDate = []}) [ Para [Str "$",Str "a",Str "_",Str "b",Str "$"] ] In contrast, markdown reader handles inline mathematics correctly. $echo "\$a_b\$" | pandoc -f markdown -t native Pandoc (Meta {docTitle = [], docAuthors = [], docDate = []}) [ Para [Math InlineMath "a_b"] ] So, it would be better to discuss this on the pandoc mailing list.

$echo "\$a_b\$" | pandoc -f rst -t native

Pandoc (Meta {docTitle = [], docAuthors = [], docDate = []}) [ Para [Str "$",Str "a",Str "_",Str "b",Str "$"] ]

In contrast, markdown reader handles inline mathematics correctly.

$echo "\$a_b\$" | pandoc -f markdown -t native

Pandoc (Meta {docTitle = [], docAuthors = [], docDate = []}) [ Para [Math InlineMath "a_b"] ]

So, it would be better to discuss this on the pandoc mailing list.

Ok, thanks. I'm using now markdown instead of rest. If someone is interested, it looks fine using: \usemodule[filter] \defineexternalfilter[markdown][filtercommand={pandoc -f markdown -t context -o \externalfilteroutputfile\space \externalfilterinputfile}] \starttext \startmarkdown Right Left Center Default ------- ------ ---------- ------- $h_1$ 12 12 12 123 123 123 123 1 1 1 1 \stopmarkdown \stoptext Sorry for the noise.

Dear ConTeXt folks,

the filter module installed using

$ ./first-setup.sh --extras="t-filter"

does not work with the following example, which is also attached.

\usemodule[filter] \defineexternalfilter[rest][filtercommand={pandoc -f rst -t context -o \externalfilteroutputfile\space \externalfilterinputfile}] \starttext There should be a table here. \startrest ========= ========= test table ========= ========= α b c d ======== ======== \stoprest \stoptext

Hi Paul, this should now work ootb as inline code with the reST module[1]. (There was some catcode inconsistency concerning spaces that I just wiped out.) Usage example appended. Best regards Philipp [1] https://bitbucket.org/phg/context-rst

...

The output file `minimal-temp-rest.tex` is just empty.

Replacing »α« by »a« solves the problem.

Running `filtercommand` in a terminal produces the *correct* output though and no empty file.

Is that a known problem?

I also include a patch adding this example into `tests/` in [1].

Thanks,

Paul

I finally had some time to try it out. Unfortunately the α is not printed either with the test file.

of course latin modern doesn’t provide Greek letters yet -- you’ll need to load another font.
