[t-vim] Line numbers

[t-vim] Line numbers

[Marco]

Hi everybodyoy
Hi Aditya

I like your t-vim module. I think it's a nice concept not te reinvent the
wheel and to take advantage of the hundreds of syntax files of the vim
contributors.

1) You have »Add line numbers« on your TODO list. What's the progress?
2) To set the font size I do the following, is there a better solution like
   bodyfont=xyz for definetyping or is it just fine like this?

\definevimtyping [PHP] [
  syntax=php,
  before={\switchtobodyfont[small]},
]

No. I will look into them. I think that I should just be able to plug in 
ConTeXt's line numbering mechanism.

I think that the best idea is to add a style=..., and color=..., key. 
In fact, I have added these keys to t-filter module. If you get the latest 
version of the module from github[1], then you should be able to say:

\definevimtyping
    [PHP]
    [syntax=php,
     style={\switchtobodyfont[small]\setupinterlinespace},
    ]

I will upload a new version soon.

PS: The style=.. and color=... attributes only work with MkIV. I need to 
think of a good way to get them to work in MkII.

I like the »just« in your sentence :)  That would be awesome.

That's fine for me.

Check the latest dev version of t-vim.
https://github.com/adityam/filter/blob/dev/t-vim.tex

I have not documented all the details, but the example at 
https://github.com/adityam/filter/blob/dev/tests/vim/line.tex should get 
you started.

Brilliant. Works like a charm.

I stumbled over one thing: When set directory=tmp the temporary files are sent
to the tmp directory except the md5 hashes of external file code, these are
put in the working dir. Example:

%%% t.tex %%%

\usemodule [vim]
\definevimtyping [CON] [
     syntax=context,
  directory=tmp,
]

\starttext
\typeCONfile {t.tex}
\startCON
% empty
\stopCON
\stoptext

%%%%%%%%%%%%%

Is it possible to convince the context script to remove the temporary stuff
when called with the --purgeall option?

Thanks for your work.

Marco

The md5 hashes are in the same directory as the file. So, in case you are 
including a file from the current directory, the md5 hash will also be 
there. So, the easiest solution is to move (or perhaps simlink) the file 
to the temporary directory. Then you can include the file tmp/t.tex and 
the md5 hash will be created in the tmp directory.

I will look into that. I guess that the easiest way out is that, instead 
of using .vimout extension, I use .tmp extension. Then, all the temporary 
files will be removed by --purgeall.

So it's on purpose. I wasn't sure about that.

It will probably work, but is not a nice solution in my opinion. It looks
strange that the document includes files from the tmp directory. From a tmp
directory I expect to be able to delete the content without any effects.

Anyway, I don't really care, since I usually don't delete the temporary files.

I don't think so. AFAIK --purgeall only deletes .tmp files with the basename
as the document itself.

I think it would make sense to convince --purgeall to be more grabby and to
remove all .tmp files in the working dir + all files in the »directory« dir
(here tmp). But I'm not sure about possible displeasing side effects, though.

I do not make that assumption in t-vim. Currently there is no way to 
specify the output directory to mtxrun --ifchanged. So, the only way that 
I can implement this feature is to either manually copy the input file, or 
manually copy the md5 file. I do not think that either of these options is 
worth the trouble.

I am not sure what you want. Do you want

context --purge filename

to remove all the temp files that t-vim creates, or do you want

context --purgeall

to delete all the files created by t-vim that reside in the current 
directory?

No, definitely not.

This will probably be difficult to implement, since the complete directory
tree has to be scanned to find xyz-externalfilter-abc-X.___ remains. However


context --purgeall filename

should remove all temporary files belonging to the document like

filename-externalfilter-CON-0.tmp     % not removed
filename-externalfilter-CON-0.tmp.md5 % not removed
filename-externalfilter-CON-0.vimout  % not removed

So after the project is done one can run context --purgeall filename to get a
clean directory structure without having to archive 30 temporary files.

Actually, `context --purgeall` deteles all the files with .tmp and .md5 
extension in the current directory. Only the .vimout files remain.

Why not simply run `context --purgeall` (no filename)? I will check how to 
ensure that .vimout files are also removed. The t-gnuplot module does 
something similar. So, perhaps I can borrow code from that.

Does it on your system? Not on mine. If I compile the example posted earlier
in the thread and execute context --purgeall afterwards, the files

t-externalfilter-CON-0.tmp.md5 and
t.tex.md5

still remain.

See above.

You are right. Only the .tmp files are removed.

@Hans: Can I somehow "register" temporary files that will be later removed 
by `context --purgeall`?

you can register to-be-cleaned-up temp files with

luatex.registertempfile(name)

(namespace might change at some point)

I don't know how to implement this functionality and still provide a 
working pdf. To save time, t-vim (actually t-filter with continue=yes) 
runs the external filter only in the first run; in the subsequent runs the 
cached file is used. So, if I want to delete the temporary files, they 
must be deleted in the last run. Right now, there is no means of detecting 
the last run in MkIV.

In MkII, we can force a final run with --final, but there is no means to 
detect that run. Even if the mode could be detected, asking context to 
delete temporary files forces another run, so the attachments will be 
missing in the final run.

I am happy to provide the 'purge temp files' as a MkIV only feature, but I 
don't know how to force (and detect) a final run in MkIV.

No problem. I'm very satisfied with the module at this state. It would just be
a nice-to-have feature.

The only thing that comes to my mind is to delete the files (of course only
when --purgeall is set) after *every* run. That's quite inefficient (since vim
is run every time again) but it would produce correct ouput and delete the
files.

I don't understand the reason behind this behaviour. Does it make sense?

The next version of t-filter will name the generated files as:

\jobname-temp-<filtername>.<filterextension>

and these files will be deleted by context --purge (in the next beta). 
Note that this will **not** delete the files in the temp directory. 
Neither will it delete "filename.ext.md5" if you use

    \type<vim>file{filename.ext}

Perhaps, in the future, it might be better to store the md5 sums in the 
tuc files; but, right now, that is a low priority feature.
