Re: [NTG-context] Kerning between primes and left parenthesis (again)

[Mikael P. Sundqvist]

Den 12 juli 2017 10:17 fm skrev "Mikael P. Sundqvist" :

Dear Hans,

now, in luatex 1.05, that the primes are "constructed" in new manner,
I wonder if there is a way to specify in a goodie file the kerning
between characters, in particular primes and the left parenthesis?

I tried

kernpairs = {
   [0x2032] = {[0x0028] = -1000, }, -- prime and (
},

but that does not seem to have any effect.

The pre-1.05 modification

dimensions = {
default = {
[0x2044] = { xoffset = 275, width = 600 },
[0x2032] = { xoffset = 50, width = 290 }, -- prime
[0x2033] = { xoffset = 50, width = 690 }, -- double prime
[0x2034] = { xoffset = 50, width = 1090}, -- triple prime
[0x2057] = { xoffset = 50, width = 1490}, -- quadruple prime
},
},

(which is a non-optimal way of solving this issue since it has side
effects) does not change anything anymore.

So, is there now a way to do this cleanly now that the mechanism is changed?

/Mikael


Hi,

should I interpret the silence that this is currently not possible, or that
you, Hans, is completely fed up with this subject? :-)

By default, the highlighting is done using the bars mechanism. It works 
for simple cases but fails with math mode (the spaces are not covered). 
One option is to highlight using the textbackground mechanism:


\definetextbackground[texthighlight]
 [
   background=color,
   backgroundcolor=gray,
   frame=off,
 ]

\define[1]\texthighlight{\starttexthighlight#1\stoptexthighlight}

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on, 
highlightcommand=\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
   print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
   print(x)
\stoppython
\stoptext

Thank you, this works much better (critic on high level: the sum symbol is
higher than the highlight box, relevant on fractions).


Another option (slightly better visually, but increases the interline 
distance)


\defineframed[texthighlight]
[
  background=color,
  backgroundcolor=gray,
  frame=off,
  location=middle,
]

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on,
highlightcommand=\dontleavehmode\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
  print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
  print(x)
\stoppython
\stoptext

By default, the highlighting is done using the bars mechanism. It works 
for simple cases but fails with math mode (the spaces are not covered). 
One option is to highlight using the textbackground mechanism:

\definetextbackground[texthighlight]
 [
   background=color,
   backgroundcolor=gray,
   frame=off,
 ]

\define[1]\texthighlight{\starttexthighlight#1\stoptexthighlight}

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on, 
highlightcommand=\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
   print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
   print(x)
\stoppython
\stoptext

The spacing in math mode is bad. What is happening is the following. To 
make sure that spaces are obeyed in the code listing, I set (a modified 
version of) \activatespacehandler{on}, so the output that you get is the 
following:

{\obeyspaces
  \def\obeyedspace{\hskip\interwordspace\relax}
\m{\sum_{i=1}^{n}i \in F \int_i f}}

The simplest way to fix this is to define a new command:

\define[1]\MATH{\bgroup\activatespacehandler{off}\m{\rescan{#1}}\egroup}


Why not just this?

\def\obeyedspace{\ifmmode\else\hskip\interwordspace\relax\fi}


That's a good suggestion and will be easier to incorporate in t-vim.

I saw the strange spacing. Thank you very much to provide a solution.

Hi,

I have two questions with the vim module.

1. I want to use the math mode inside the code. I've seen the escape option,
e.g. here [1], but this seems to work only with comments. Is there a

Short answer. No.

Long answer. t-vim relies on vim to syntax highlight the code. Since the
code is not valid python, the default python syntax highlighting will not
work. In principle, it is possible to write a vim syntax highlighting
script for a derivative of python where math terms are allowed, but that
requires a lot of work for each language. The whole point of t-vim module
was that I am lazy and don't want to write the parser for each language
:-)


I've invested some time and rewrote parts of the vimscript file of t-vim.
Now one or more escapechars can be defined, that helps vim to not interpret
the text:


I'll look at this later


Another point I saw is, that highlight together with TeX-code is not really 
usable:
```
\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on]

\starttext
\startpython[highlight=1]
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
\stoppython
\stoptext
```

for x in 1:n
  print(x)

 Hi,
 
 For those using synctex, an alternative method is:
 
 \setupsynctex[state=start]
 
 It is tuned for use in a more complex setup where one wants access to 
 source files (with content) and not to e.g. styles in a tex tree. It also 
 works reasonable well with (also included) xml files. Personally I never 
 use synctex but for some projects it came in handy for authors (think of 
 proofing xml files with hundreds of nested inclusions and files in a 
 rather branched tree.) Of course you can expect a similar performance hit 
 as normal synctex but commenting the above line in production results in 
 zero overhead. Using the syntex flag on the command line 
 (--synctex=context will work) can be messy.
 
 This currently only works with the windows binaries version on the garden
