\subject{About \SCITE}

{\em This manual is under (re)construction.}

For a long time at \PRAGMA\ we used \TEXEDIT, an editor we'd written in \MODULA.
It had some project management features and recognized the project structure in
\CONTEXT\ documents. Later we rewrote this to a platform independent
reimplementation called \TEXWORK\ written in \PERLTK\ (not to be confused with
the editor with the plural name).

In the beginning of the century I can into \SCITE, written by Neil Hodgson.
Although the mentioned editors provide some functionality not present in \SCITE\
we decided to use that editor because it frees us from maintaining our own. I
ported our \TEX\ and \METAPOST\ (line based) syntax highlighting to \SCITE\ and
got a lot of others for free.

After a while I found out that there was an extension interface written in \LUA.
I played with it and wrote a few extensions too. This pleasant experience later
triggered the \LUATEX\ project.

A decade into the century \SCITE\ got another new feature: you can write dynamic
external lexers in \LUA\ using \LPEG. As in the meantime \CONTEXT\ has evolved in
a \TEX/\LUA\ hybrid, it made sense to look into this. The result is a couple of
lexers that suit \TEX, \METAPOST\ and \LUA\ usage in \CONTEXT\ \MKIV. As we also
use \XML\ as input and output format a lexer for \XML\ is also provided. And
because \PDF\ is one of the backend formats lexing of \PDF\ is also implemented.
\footnote {In the process some of the general lexing framework was adapted to
suit our demands for speed. We ship these files as well.}

In the \CONTEXT\ (standalone) distribution you will find the relevant files
under:

\starttyping
<texroot>/tex/texmf-context/context/data/scite
\stoptyping

Normally a user will not have to dive into the implementation details but in
principle you can tweak the properties files to suit your purpose.

\subject{The look and feel}

The color scheme that we use is consistent over the lexers but we use more colors
that in the traditional lexing. For instance, \TEX\ primitives, low level \TEX\
commands, \TEX\ constants, basic file structure related commands, and user
commands all get a different treatment. When spell checking is turned on, we
indicate unknown words, but also words that are known but might need checking,
for instance because they have an uppercase character. In \in {figure}
[fig:colors] we some of that in practice.

\placefigure
  [page]
  [fig:colors]
  {Nested lexers in action.}
  {\rotate
     [rotation=90]

        [scite-context-visual.png]
        [maxheight=1.2\textwidth,
         maxwidth=.9\textheight]}}

\subject{Installing \SCITE}

Installing \SCITE\ is straightforward. We are most familiar with \MSWINDOWS\ but
for other operating systems installation is not much different. First you need to
fetch the archive from:

\starttyping
www.scintilla.org
\stoptyping

The \MSWINDOWS\ binaries are zipped in \type {wscite.zip}, and you can unzip this
in any directory you want as long as you make sure that the binary ends up in
your path or as shortcut on your desktop. So, say that you install \SCITE\ in:

\starttyping
c:\data\system\scite\wscite
\stoptyping

You need to add this path to your local path definition. Installing \SCITE\ to
some known place has the advantage that you can move it around. There are no
special dependencies on the operating system.

Next you need to install the lpeg lexers. \footnote {Versions later than 2.11
will not run on \MSWINDOWS\ 2K. In that case you need to comment the external
lexer import.} These can be fetched from:

\starttyping
http://foicica.com/scintillua/
\stoptyping

On \MSWINDOWS\ you need to copy the \type {lexers} subfolder to the \type
{wscite} folder. For \LINUX\ the place depends on the distribution and I just
copy them in the same path as where the regular properties files live. \footnote
{If you update, don't do so without testing first. Sometimes there are changes in
\SCITE\ that influence the lexers in which case you have to wait till we have
update them to suit those changes.}

For \UNIX, one can take a precompiled version as well. Here we might need to split
the set of files into:

\starttyping
/usr/bin
/usr/share/scite
\stoptyping

The second path is hard coded in the binary and moving all files there probably works
okay. Beware: if you're on a 64 bit system, you need to rename the 64 bit \type {so}
library.

If you want to use \CONTEXT, you need to copy the relevant files from

\starttyping
<texroot>/tex/texmf-context/context/data/scite
\stoptyping

to the path were \SCITE\ keeps its property files (\type {*.properties}). There
is a file called \type {SciteGlobal.properties}. At the end of that file (on
\MSWINDOWS\ it is in the path where the Scite binary) you then add a line to the
end:

\starttyping
import scite-context-user
\stoptyping

You need to restart \SCITE\ in order to see if things work out as expected.

Disabling the external lexer in a recent \SCITE\ is somewhat tricky. In that case
the end of that file looks like:

\starttyping
imports.exclude=scite-context-external
import *
import scite-context-user
\stoptyping

In any case you need to make sure that the user file is loaded last.

After this, things should run as expected (given that \TEX\ runs at the console
as well).

% In order to run the commands needed, we assume that the following programs
% are installed:
%
% \startitemize[packed]
% \item tidy (for quick and dirty checking of \XML\ files)
% \item xsltproc (for converting \XML\ files into other formats)
% \item acrobat (for viewing files)
% \item ghostview (for viewing files, use gv on \UNIX)
% \item rxvt (a console, only needed on \UNIX)
% \stopitemize

\subject{Fonts}

The configuration file defaults to the Dejavu fonts. These free fonts are part of
the \CONTEXT\ suite (also known as the standalone distribution). Of course you
can fetch them from \type {http://dejavu-fonts.org} as well. You have to copy
them to where your operating system expects them. In the suite they are available
in

\starttyping
<contextroot>/tex/texmf/fonts/truetype/public/dejavu
\stoptyping

\subject{An alternative approach}

If for some reason you prefer not to mess with property files in the main \SCITE\
path, you can follow a different route and selectively copy files to places.

The following files are needed for the lpeg based lexer:

\starttyping
lexers/scite-context-lexer.lua
lexers/scite-context-lexer-tex.lua
lexers/scite-context-lexer-mps.lua
lexers/scite-context-lexer-lua.lua
lexers/scite-context-lexer-cld.lua
lexers/scite-context-lexer-txt.lua
lexers/scite-context-lexer-xml*.lua
lexers/scite-context-lexer-pdf*.lua

lexers/context/data/scite-context-data-tex.lua
lexers/context/data/scite-context-data-context.lua
lexers/context/data/scite-context-data-interfaces.lua
lexers/context/data/scite-context-data-metapost.lua
lexers/context/data/scite-context-data-metafun.lua

lexers/themes/scite-context-theme.lua
\stoptyping

The data files are needed because we cannot access property files from within the
lexer. If we could open a file we could use the property files instead.

These files go to the \type {lexers} subpath in your \SCITE\ installation.
Normally this sits in the binary path. The following files provide some
extensions. On \MSWINDOWS\ you can copy these files to the path where the \SCITE\
binary lives.

\starttyping
scite-ctx.lua
\stoptyping

Because property files can only be loaded from the same path where the (user)
file loads them you need to copy the following files to the same path where the
loading is defined:

\starttyping
scite-context.properties
scite-context-internal.properties
scite-context-external.properties

scite-pragma.properties

scite-tex.properties
scite-metapost.properties

scite-context-data-tex.properties
scite-context-data-context.properties
scite-context-data-interfaces.properties
scite-context-data-metapost.properties
scite-context-data-metafun.properties

scite-ctx.properties
scite-ctx-context.properties
scite-ctx-example.properties
\stoptyping

On \MSWINDOWS\ these go to:

\starttyping
c:/Users/YourName
\stoptyping

Next you need to add this to:

\starttyping
import scite-context
import scite-context-internal
import scite-context-external
import scite-pragma
\stoptyping

to the file:

\starttyping
SciTEUser.properties
\stoptyping

Of course the pragma import is optional. You can comment either the internal or
external variant but there is no reason not to keep them both.

\subject{Extensions}

Just a quick not to some extensions. If you select a part of the text (normally
you do this with the shift key pressed) and you hit \type {Shift-F11}, you get a
menu with some options. More (robust) ones will be provided at some point.

\subject{Spell checking}

If you want to have spell checking, you need have files with correct words on
each line. The first line of a file determines the language:

\starttyping
% language=uk
\stoptyping

When you use the external lexers, you need to provide some files. Given that you
have a text file with valid words only, you can run the following script:

\starttyping
mtxrun --script scite --words nl uk
\stoptyping

This will convert files with names like \type {spell-nl.txt} into \LUA\ files
that you need to copy to the \type {lexers/data} path. Spell checking happens
realtime when you have the language directive (just add a bogus character to
disable it). Wrong words are colored red, and words that might have a case
problem are colored orange. Recognized words are greyed and words with less than
three characters are ignored.

In the case of internal lexers, the following file is needed:

\starttyping
spell-uk.txt
\stoptyping

If you use the traditional lexer, this file is taken from the path determined by
the environment variable:

\starttyping
CTXSPELLPATH
\stoptyping

As already mentioned, the lpeg lexer expects them in the data path. This is
because the \LUA\ instance that does the lexing is rather minimalistic and lacks
some libraries as well as cannot access the main \SCITE\ state.

Spell checking in \type {txt} files is enabled by adding a first line:

\starttyping
[#!-%] language=uk
\stoptyping

The first character on that line is one of the four mentioned between square
brackets. So,

\starttyping
# language=uk
\stoptyping

should work. For \XML\ files there are two methods. You can use the following (at
the start of the file):

\starttyping
<?xml ... language="uk" ?>
\stoptyping

But probably better is to use the next directive just below the
usual \XML\ marker line:

\starttyping
<?context-directive editor language uk ?>
\stoptyping

\subject{Interface selection}

In a similar fashion you can drive the interface checking:

\starttyping
% interface=nl
\stoptyping

\subject{Property files}

The internal lexers are controlled by the property files while the external ones
are steered with themes. Unfortunately there is hardly any access to properties
from the external lexer code nor can we consult the file system and/or run
programs like \type {mtxrun}. This means that we cannot use configuration files
in the \CONTEXT\ distribution directly. Hopefully this changes with future
releases.

\subject{The external lexers}

These are the more advanced. They provide more detail and the \CONTEXT\ lexer
also supports nested \METAPOST\ and \LUA. Currently there is no detailed
configuration but this might change once they are stable.

The external lexers operate on documents while the internal ones operate on
lines. This can make the external lexers slow on large documents. We've optimized
the code somewhat for speed and memory consumption but there's only so much one
can do. While lexing each change in style needs a small table but allocating and
garbage collecting many small tables comes at a price. Of course in practice this
probably gets unnoticed. \footnote {I wrote the code in 2011 on a more than 5
years old Dell M90 laptop, so I suppose that speed is less an issue now.}

In principle the external lexers can be used with \type {textadept} which also
uses \type {scintilla}. Actually, support for lpeg lexing originates in \type
{textadept}. Currently \type {textadept} lacks a couple of features I like about
\SCITE\ (for instance it has no realtime logpane) and it's also still changing.
At some point the \CONTEXT\ distribution might ship with files for \type
{textadept} as well.

The external lpeg lexers work okay with the \MSWINDOWS\ and \LINUX\ versions of
\SCITE, but unfortunately at the time of writing this, the \LUA\ library that is
needed is not available for the \MACOSX\ version of \SCITE. Also, due to the fact
that the lexing framework is rather isolated, there are some issues that cannot
be addressed in the properly, at least not currently.

In addition to \CONTEXT\ and \METAFUN\ lexing a \LUA\ lexer is also provided so
that we can handle \CONTEXT\ \LUA\ Document (\CLD) files too. There is also an
\XML\ lexer. This one also provides spell checking. The \PDF\ lexer tries to do a
good job on \PDF\ files, but it has some limitations. There is also a simple text
file lexer that does spell checking.

Don't worry if you see an orange rectangle in your \TEX\ or \XML\ document. This
indicates that there is a special space character there, for instance \type
{0xA0}, the nonbreakable space. Of course we assume that you use \UTF8 as input
encoding.

\subject{The internal lexers}

\SCITE\ has quite some built in lexers. A lexer is responsible for highlighting
the syntax of your document. The way a \TEX\ file is treated is configured in the
file:

\starttyping
tex.properties
\stoptyping

You can edit this file to your needs using the menu entry under \type {options}
in the top bar. In this file, the following settings apply to the \TEX\ lexer:

\starttyping
lexer.tex.interface.default=0
lexer.tex.use.keywords=1
lexer.tex.comment.process=0
lexer.tex.auto.if=1
\stoptyping

The option \type {lexer.tex.interface.default} determines the way keywords are
highlighted. You can control the interface from your document as well, which
makes more sense that editing the configuration file each time.

\starttyping
% interface=all|tex|nl|en|de|cz|it|ro|latex
\stoptyping

The values in the properties file and the keywords in the preamble line have the
following meaning:

\starttabulate[|lT|lT|p|]
\NC 0 \NC all   \NC all commands (preceded by a backslash)                \NC \NR
\NC 1 \NC tex   \NC \TEX, \ETEX, \PDFTEX, \OMEGA\ primitives (and macros) \NC \NR
\NC 2 \NC nl    \NC the dutch \CONTEXT\ interface                         \NC \NR
\NC 3 \NC en    \NC the english \CONTEXT\ interface                       \NC \NR
\NC 4 \NC de    \NC the german \CONTEXT\ interface                        \NC \NR
\NC 5 \NC cz    \NC the czech \CONTEXT\ interface                         \NC \NR
\NC 6 \NC it    \NC the italian \CONTEXT\ interface                       \NC \NR
\NC 7 \NC ro    \NC the romanian \CONTEXT\ interface                      \NC \NR
\NC 8 \NC latex \NC \LATEX\ (apart from packages)                         \NC \NR
\stoptabulate

The configuration file is set up in such a way that you can easily add more
keywords to the lists. The keywords for the second and higher interfaces are
defined in their own properties files. If you're curious about the way this is
configures, you can peek into the property files that start with \type
{scite-context}. When you have \CONTEXT\ installed you can generate configuration
files with

\starttyping
mtxrun --script interface --scite
\stoptyping

You need to make sure that you move the result to the right place so best not
mess around with this command and use the files from the distribution.

Back to the properties in \type {tex.properties}. You can disable keyword
coloring alltogether with:

\starttyping
lexer.tex.use.keywords=0
\stoptyping

but this is only handy for testing purposes. More interesting is that you can
influence the way comment is treated:

\starttyping
lexer.tex.comment.process=0
\stoptyping

When set to zero, comment is not interpreted as \TEX\ code and it will come out
in a uniform color. But, when set to one, you will get as much colors as a \TEX\
source. It's a matter of taste what you choose.

The lexer tries to cope with the \TEX\ syntax as good as possible and takes for
instance care of the funny \type {^^} notation. A special treatment is applied to
so called \type {\if}'s:

\starttyping
lexer.tex.auto.if=1
\stoptyping

This is the default setting. When set to one, all \type {\ifwhatever}'s will be
seen as a command. When set to zero, only the primitive \type {\if}'s will be
treated. In order not to confuse you, when this property is set to one, the lexer
will not color an \type {\ifwhatever} that follows an \type {\newif}.

\subject{The \METAPOST\ lexer}

The \METAPOST\ lexer is set up slightly different from its \TEX\ counterpart,
first of all because \METAPOST\ is more a language that \TEX. As with the \TEX\
lexer, we can control the interpretation of identifiers. The \METAPOST\ specific
configuration file is:

\starttyping
metapost.properties
\stoptyping

Here you can find properties like:

\starttyping
lexer.metapost.interface.default=1
\stoptyping

Instead of editing the configuration file you can control the lexer with the
first line in your document:

\starttyping
% interface=none|metapost|mp|metafun
\stoptyping

The numbers and keywords have the following meaning:

\starttabulate[|lT|lT|p|]
\NC 0 \NC none           \NC no highlighting of identifiers   \NC \NR
\NC 1 \NC metapost or mp \NC \METAPOST\ primitives and macros \NC \NR
\NC 2 \NC metafun        \NC \METAFUN\ macros                 \NC \NR
\stoptabulate

Similar to the \TEX\ lexer, you can influence the way comments are handled:

\starttyping
lexer.metapost.comment.process=1
\stoptyping

This will interpret comment as \METAPOST\ code, which is not that useful
(opposite to \TEX, where documentation is often coded in \TEX).

The lexer will color the \METAPOST\ keywords, and, when enabled also additional
keywords (like those of \METAFUN). The additional keywords are colored and shown
in a slanted font.

The \METAFUN\ keywords are defined in a separate file:

\starttyping
metafun-scite.properties
\stoptyping

You can either copy this file to the path where you global properties files lives,
or put a copy in the path of your user properties file. In that case you need to
add an entry to the file \type {SciTEUser.properties}:

\starttyping
import metafun-scite
\stoptyping

The lexer is able to recognize \type {btex}||\type {etex} and will treat anything
in between as just text. The same happens with strings (between \type {"}). Both
act on a per line basis.

\subject{Using \ConTeXt}

When \type {mtxrun} is in your path, \CONTEXT\ should run out of the box. You can
find \type {mtxrun} in:

\starttyping
<contextroot>/tex/texmf-mswin/bin
\stoptyping

or in a similar path that suits the operating system that you use.

When you hit \type{CTRL-12} your document will be processed. Take a look at the
\type {Tools} menu to see what more is provided.

\subject{Extensions (using \LUA)}

When the \LUA\ extensions are loaded, you will see a message in the log pane that
looks like:

\starttyping
-  see scite-ctx.properties for configuring info

-  ctx.spellcheck.wordpath set to ENV(CTXSPELLPATH)
-  ctxspellpath set to c:\data\develop\context\spell
-  ctx.spellcheck.wordpath expands to c:\data\develop\context\spell

-  ctx.wraptext.length is set to 65
-  key bindings:

Shift + F11   pop up menu with ctx options

Ctrl  + B     check spelling
Ctrl  + M     wrap text (auto indent)
Ctrl  + R     reset spelling results
Ctrl  + I     insert template
Ctrl  + E     open log file
Ctrl  + +     show language character strip (key might change)

-  recognized first lines:

xml   <?xml version='1.0' language='nl'
tex   % language=nl
\stoptyping

This message tells you what extras are available. The language character strip feature
is relatively new and displays buttons at the bottom of the screen for the characters
in a (chosen) language. This is handy when you occasionally have to key in (snippets) of
a language you're not familiar with. More alphabets will be added (we take data from some
\CONTEXT\ language relates files).

\subject{Templates}

There is an experimental template mechanism. One option is to define templates in
a properties file. The property file \type {scite-ctx-context} contains
definitions like:

\starttyping
command.25.$(file.patterns.context)=insert_template \
$(ctx.template.list.context)

ctx.template.list.context=\
    itemize=structure.itemize.context|\
    tabulate=structure.tabulate.context|\
    natural TABLE=structure.TABLE.context|\
    use MP graphic=graphics.usemp.context|\
    reuse MP graphic=graphics.reusemp.context|\
    typeface definition=fonts.typeface.context

ctx.template.structure.itemize.context=\
\startitemize\n\
\item ?\n\
\item ?\n\
\item ?\n\
\stopitemize\n
\stoptyping

The file \type {scite-ctx-example} defines \XML\ variants:

\starttyping
command.25.$(file.patterns.example)=insert_template \
$(ctx.template.list.example)

ctx.template.list.example=\
    bold=font.bold.example|\
    emphasized=font.emphasized.example|\
    |\
    inline math=math.inline.example|\
    display math=math.display.example|\
    |\
    itemize=structure.itemize.example

ctx.template.structure.itemize.example=\
<itemize>\n\
<item>?</item>\n\
<item>?</item>\n\
<item>?</item>\n\
</itemize>\n
\stoptyping

For larger projects it makes sense to keep templates with the project. In one of
our projects we have a directory in the path where the project files are kept
which holds template files:

\starttyping
..../ctx-templates/achtergronden.xml
..../ctx-templates/bewijs.xml
\stoptyping

One could define a template menu like we did previously:

\starttyping
ctx.templatelist.example=\
    achtergronden=mathadore.achtergronden|\
    bewijs=mathadore.bewijs|\

ctx.template.mathadore.achtergronden.file=smt-achtergronden.xml
ctx.template.mathadore.bewijs.file=smt-bewijs.xml
\stoptyping

However, when no such menu is defined, we will automatically scan the directory
and build the menu without user intervention.

\subject{Using \SCITE}

The following keybindings are available in \SCITE. Most of this list is taken
from the on|-|line help pages.

\startbuffer[keybindings]
\starttabulate[|l|p|]
\FL
\NC \rm \bf keybinding   \NC \bf meaning (taken from the \SCITE\ help file)                                \NC \NR
