@DavidCarlisle ooh

@PauloCereda .....

@DavidCarlisle hi <3

@UlrikeFischer I think it would be OK to just rename README to README.md that would match the current position where mirrors.ctan.org/support/pdfcrop/README is the long form.

@DavidCarlisle I see Petra complained as expected ;-). I will sort it out (and look if I can find something to let pdfcrop find ghostscript in the git bash too without disturbing curious cygwin installations ...).

@UlrikeFischer OK thanks

@UlrikeFischer as long as it finds gs via the path I don't think the cygwin gs launched via a cygwin perl will pick up any native windows versions unless you do something really strange

@DavidCarlisle pdfcrop does a long search for ghostscript in many places and then use the first hit, so I was considering to simply extend the list for unix (which is the path used in the bash):

  my %candidates = (
        'unix' => [qw|gs gsc gswin64c gswin32c|],
        'dos' => [qw|gs386 gs|],
        'os2' => [qw|gsos2 gs|],
        'win' => [qw|gswin64c gswin32c gs|],
        'cygwin' => [qw|gs gswin32c|],
        'miktex' => [qw|mgs gswin64c gswin32c gs|]
    );

Does that look resonable?

@UlrikeFischer yes I would guess it mostly uses relative paths anyway so picking up the gswin versions will be better than nothing. in cygwin absolute paths won't work as if cygwin perl passes a file like /users/zzz/foo.pdf then a native windows gs will need c:/cygwin64/users/zzz/foo.pdf as the "root" of the cygwin filesystem isn't at teh top of the windows filesystem

@DavidCarlisle I didn't change the cygwin entry only unix (and added gswin64c to win and miktex), but I could add gswin64c to cygwin too.

@DavidCarlisle ah no, that is not needed I just saw the following code: it will look for gswin64c automatically for win, cygwin and miktex. I need to check how to handle unix here.

@DavidCarlisle how do one setup such "tabular lists" like the history in markdown?

@UlrikeFischer if ctan markdown supports tables (most, including github, do) you could mark it as a table, using | betwwwn the cells (and a blank line at the start) or just as an itemized list with - at start of each line

How can I use align* inside \[ ... \] math mode?

I'd like to typeset \[ blah = \left\{ \begin{align*} ... \end{align*} \right. \]

@ComFreek you don't. Just use align*

so i should nest two align*?

@ComFreek use aligned not align*

works thank you!

@ComFreek but for that better to use the custom cases environment which adds the { automatically

\begin{align*}
	&s\colon \sortType &&\mapsto \begin{cases}
		&\domc{s}&&\colon \sortType\\
		&\codc{s}&&\colon \sortType\\
		&h_s&&\colon \domc{s} \to \codc{s}
	\end{cases}
\end{align*}

that gives "extra alignment tab has been changed to \cr"

Can't I use cases within align*?

@ComFreek cases can only have two columns

@DavidCarlisle ok. So simply like in pdftexcmds LATEX Project Public License, version 1.3c or later.

@UlrikeFischer I'd copy the format from pdftexcmds/README.md (just with different dates) so:

## Copyright (C)
* 2007, 2009-2011  Heiko Oberdiek
* 2016-2020        Oberdiek Package Support Group

## License
LATEX Project Public License, version 1.3c or later.

@UlrikeFischer oh that's what you said:-) so yes

I suspect I am a nerd

@DavidCarlisle I have now moved the whole content of the old readme to readme.md (hard work to get a markdown table to behave ...). I also adapted the licence and the authors everywhere (I hope) to 1.3c + HO+Oberdiek Group. if you could take a look then I can update again.

@UlrikeFischer OK pulling now..

@UlrikeFischer checking the markdown at github.com/ho-tex/pdfcrop the "Windows" heading was still in the unix list so I just pushed a change unindenting it. Oh copyright, I'll fix here..

@UlrikeFischer pushed a couple of things but looks fine thanks

@DavidCarlisle I checked against the ctan tester and there it worked - markdown isn't easy ;-) (the main problem was that the ctan markdown doesn't like empty table cells). Thanks for looking I will upload now.

@UlrikeFischer :)

@JosephWright did you fight with this too?

@JosephWright any objections to me pushing the vi PR, I resolved the merge conflicts here...

@DavidCarlisle Go for it

@JosephWright done. scary number of accents added :-)

@DavidCarlisle and the only word I recognized in lesson14 (latin1) made me look at the english text. I think Unicode-encoded should be utf8 shouldn't it? And the paragraph sounds a bit odd, as it is unclear if with "modern pdflatex" one should still use latin1 or not.

@DavidCarlisle Wow: I didn't realise he'd done the full job

@JosephWright yes

@UlrikeFischer yes utf8-encoded would be better than unicode-encoded

@DavidCarlisle can you change it? I'm away now.

Hello, I have been away for a while. Glad to see you again. I was wondering... Can MathJax be considered a TeX engine?

@bp2017 no

@bp2017 it doesn't really have any execution paths that resemble tex in any way

@DavidCarlisle, well, OK. Thanks.

@bp2017 it's pretty impressive javascript though:-)

@DavidCarlisle, yeah, and it goes along with SVG drawings well (to mimic pgf).

@bp2017 hopefully one day it won't be needed but we're not there yet

@DavidCarlisle, we are never there :)

@DavidCarlisle, I'm trying to make a simple animation with "animate" package. Hopefully I come up with something later today.

@PauloCereda -- Was there ever any question?

@bp2017 but perhaps closer than we have been for some time to getting math support in browsers

@PabloGonzálezL yep, already saw it :)

Puhh......

@cis wow, you were diligent!

@Skillmonlikestopanswers.xyz Yes, unfortunately. Or obsessed.

@UlrikeFischer yes I'll do something
