filter and/or vim module in current beta

filter and/or vim module in current beta

[Andreas Schneider]

Hi,

it seems the filter module doesn't currently work (in MkIV at least). It 
may be a problem with the vim module though, I'm not quite sure.

The following example doesn't produce any output:

-----8<---------------------------------------------------
\usemodule[vim]

\definevimtyping[PASCAL][syntax=pascal]

\starttext

\startPASCAL
program test;
begin
	writeln('Hello World!');
end.
\stopPASCAL

\stoptext
-----8<---------------------------------------------------

The output of context has only one line regarding t-filter:
t-filter        > command :

I guess it's just "normal" then that there's no output ... if nothing is 
run.

Any ideas whats going wrong here?

Btw.:
ConTeXt  ver: 2011.08.26 13:32 MKIV  fmt: 2011.8.26  int: english/english

Andreas

Are you using the latest version (2011.08.23) of the filter module? The 
empty filter is due to a change in the how the context namespacing macros 
work and I fixed this a couple of days ago.

I updated via first-setup/minimals, so I hope so. But I'll double check 
later by manually grabbing the module.

The problem is with t-vim.

I need to figure out the best workaround that will work with both MkII and 
MkIV.

Fixed. Download t-vim and t-syntax-highlight from the dev branch at 
github.

https://github.com/adityam/filter/tree/dev

I'll upload a new version later.

Fixed. Again, was due to the change in the namespace handler. For a 
working version, you will need to download all the t-*.tex files from the 
dev branch at github.

The change in alternative is handled at the tex level, so there is no need 
to rerun vim

You can also use --mode=force to force a rerun.

Tabs are converted to spaces at TeX level: tab=4 gives four spaces, tab=8 
gives eight spaces. However, there was a bug due to which the spaces at 
the beginning of the line were eaten. Fixed now.

No, it was a bug. Also fixed.

Thanks! The vimout file is now created and seems to be correct. There 
are still some problems, though:

Currently, pscolor doesn't seem to work as color scheme which renders a 
default vimtyping environment (like my initial example) unhighlighted. 
Using blackandwhite works.

Here I noticed a second problem. A change to the to-be-highlighted 
buffer as well as some options (like said "alternative") isn't processed 
at all. I have to manually delete the vimout, tmp and md5 files first 
before I actually see the change.

Also it seems, that tabs are killed. If I manually replace them with 
spaces, it works. Empty lines also seem to be removed, however that 
appears to be a feature - not sure.

Works fine now.

I thought so and indeed it works now ... it was probably coincidence 
that it didn't work before.

Shouldn't it detect changes to the buffer through the md5 sum? What I 
meant was: I modify the buffer (add a line, or change lines) but that 
change doesn't cause vim to be run again. From what I can see, the tmp 
file isn't written at all, if it already exists, therefore the md5 sum 
doesn't change, therefore vim isn't run again. Shouldn't the tmp file 
always be (re)written, to reflect the content of the current buffer?

Indeed, works as expected now.

Even better (kinda ;-)).

Thank you for your efforts and the quick bug fixing!

This appears to be a Windows specific bug. os.rename does not overwrite 
file on Windows. I changed that with file.copy. Try the new version of the 
t-filter module.

Thank you for testing. The recent change in the namespace macros broke a 
lot of functionality of the filter module. Hopefully, now everything is 
working correctly.

Does it still work with TeX Live (in case it is not, it might make
sense to ask Karl not to update the package or to provide the old one
on CTAN).

I haven't tested it with TL. I will test with an old ConTeXt version to 
see if anything breaks (it should not).

OK.

Weird, I didn't expect that to be a platform specific issue. Good thing, 
you figured out I was using Windows :-)

Everything I tested works fine now, so I guess you are on the right 
track (if not even on the destination :D)

Again, Many thanks :-)
