I'm counting 27 datatypes implemented so far in Red. The next on 
the list will be: typeset!, errror!, object!, port!, binary!. Although, 
I'm not sure in which precise order they will be added (especially 
for error! and object!, not sure which one I'll do first).


For other datatypes, like float!, date! and time!, which are not 
a requirement for building Red core itself, I would like them to 
be contributed if possible. I could provide a sample empty datatype 
file and instructions on how to use Red's current internal API to 
anyone willing to work on them.

I suggest to change the relaive part of "Readme.md" to:

Running the Red/System hello script
------------------------

1. From the REBOL console type:

    `call/show ""` ; (type this only once to fix Rebol 2 bug)

    `change-dir %red-system/`

2. Type: 

    `do/args %rsc.r "%tests/hello.reds"`
	

    the compilation process should finish with a `...output file size` 
    message.


3. The resulting binary is in `red-system/builds/`, go try it! type 
(on Windows):

    `call/wait/shell/console %builds/hello.exe`

I've started a file common.red for common definitions for Red:
http://red.esperconsultancy.nl/Red-common/dir?ci=tip

Notably, there's marshalling in there for program arguments.

ARGS-COUNT gives you the number of arguments, including the program 
file name, like system/args-count in Red/System.

ARGUMENTS gives a block of string arguments, excluding the program 
file name, or NONE, like ARGS in Boron.
ARGUMENT 0 gives the program file name, like argv[0] in C.

I'm happy to announce our next Android release. Cyphre did a great 
job and pushed the port further forward. Here are the highlights 
of the new release:

-added full file access
-added networking
-added console user input (ASK etc. works)
-improved threading (at the app level, not R3)
-misc small internal changes in the console code


With this it's possible to run R3 chat on your Android phone :-) 
Here is how to do it:

make-dir %/mnt/sdcard/r3/
change-dir %/mnt/sdcard/r3/
chat


The paths might be a bit different on your device. The trick is to 
use the /sdcard path and put everything below it.

The link is as always:

Again, thanks to all who made a donation for this project!

All file and networking tests working for me so far :)

I've extended the Red interpreter console with the ability to load 
and run a script file, given as an optional program argument. It 
also has CALL now, so you can run simple programs with the intepreter 
and script the operating system.


As before, ready built binaries are available in the test repository, 
in */Red/console-pro:
http://archives.esperconsultancy.nl/Red-test/dir?ci=tip

I made simple implementations of READ and WRITE for Red. They need 
to be included from a new file input-output.red:
http://red.esperconsultancy.nl/Red-common/dir?ci=tip

It's now possible to read and write text files with Red.

I've updated the console-pro interpreter in */Red/:
http://red.esperconsultancy.nl/Red-test/dir?ci=tip

Red doesn't have a file! type yet, so the file names need to be passed 
as strings for now

Even though file names and URLs are passed as strings, READ and WRITE 
detect which they are:

read "file.txt"
read "file:///file.txt"
read "http://devcon.esperconsultancy.nl"

Red []

#include %common/input-output.red
#include %GTK/GTK.red

load-file: function [
	field		[integer!]  ; "widget!"
	area		[integer!]  ; "widget!"
	return:		[logic!]
][
	all [
		link: get-field-text field
		not empty? link
		data: read link
		set-area-text area data
	]

view/title [
	"File/URL:" line: field "" [load-file face text]

			not empty? link
			data: get-area-text text
			write link data
		]
	]
	text: area
	button "Quit" close
] "Red GTK+ Text Editor"

In the line field, you can enter either a local file name or a URL, 
so the editor can be used both on local files and files on remote 
servers

I wrote an example of a browser for Internet sites written in Red. 
The source code is here:


http://red.esperconsultancy.nl/Red-GTK/doc/trunk/examples/GTK-browser.red


The usage model is like a web browser. You point it to network or 
local file links, in an address bar or as a command line parameter, 
and it displays them in the same content area in one window. A Red 
page can contain links that make the browser go to another page.


You can create and roll out Red sites just like websites. We are 
hosting the first Redsite here:

http://red.esperconsultancy.nl/index.red

It turns out that the C library on Windows converts Windows newlines 
in text files to standard Unix newlines, so when reading a file, 
it can return fewer bytes than requested. I have extended the Red/System 
read-file function in the C library binding to support this:

http://red.esperconsultancy.nl/Red-C-library/dir?ci=tip


This fix propagates to READ in common/input-output, console-pro, 
GTK-text-editor and GTK-browser. They can now load local text files 
with Windows newlines, including those that were originally in Unix 
format but converted when downloading.


Thanks to Doc for helping test, and to Gerard and Sqlab for additional 
reports.

Kaj, 

the problem, that the console window closed, was caused by my wong 
assumption, that the convention for file names is the same as in 
Rebol.
i.e.
read   -> crash
read %test -- > crash
write %test -- > crash
read "test"   --> works

If you need access to our source repositories or Try REBOL, you can 
temporarily define our hosts locally on your system to our current 
IP address. For example in the /etc/hosts file on Unixy systems:

I implemented UTF-8 output support for Red. I ended up writing optimised 
versions based more on the Red print backend. I integrated them in 
my I/O routines and made heavy performance optimisations. Thanks 
to Peter for leading the way. There are the following Red/System 
encoders embedded in %common.red:

http://red.esperconsultancy.nl/Red-common/dir?ci=tip


to-UTF8: encodes a Red string into UTF-8 Red/System c-string! format.

to-local-file: encodes a Red string into Latin-1 Red/System c-string! 
format on Windows, and into UTF-8 on other systems. This yields a 
string suitable for the local file name APIs. Latin-1 can be output 
as long as it was input into Red via UTF-8. Non-Latin-1 code points 
cannot be encoded in Latin-1 and yield a NULL for the entire result.


These encoders make use of the Latin1-to-UTF8, UCS2-to-UTF8 and UCS4-to-UTF8 
encoding functions. An example of their use in the Red READ and WRITE 
functions is in %input-output.red

I used the new encoding functions in all my Red bindings: those for 
the C library, input/output via files and cURL, 0MQ, SQLite and GTK+. 
In as many places as possible, data marshalled to the external libraries 
now supports UTF-8. File names on Windows support Latin-1. Files 
and URLs are always read and written as UTF-8, including on Windows. 
Red does not support loading Latin-1 strings.

I can't test the encoding on Mac, so I would be interested to hear 
if it works there, especially UTF-8 file names

I dropped the cURL dependency from my red-base distribution. This 
means that it now only depends on a few libraries that can be expected 
to be included in all platforms. This version of the Red interpreter 
can now be used on Windows as a single executable, without any extra 
libraries. The Windows version red-base.exe is here:

http://red.esperconsultancy.nl/Red-test/dir?ci=tip&name=MSDOS/Red


It has versions of READ and WRITE for local file I/O, but no network 
I/O. It also has the other functionality from the C library, such 
as INPUT, ASK, GET-ENV, CALL, NOW and RANDOM, but for more functionality 
you still have to use red-core and red, and download the extra libraries 
for Windows.

I'm happy to announce that we made good progress regarding the Android 
R3 encapper.


A major breakthru in the multiple-app generation has been made (thanks 
to Andreas for ELF format hints). Now it is possible to create encapped 
apps with unique app-id. Such apps can be recognized properly by 
the Android OS and also accepted on the Google Play market.


The cool thing with this approach is one really don't need anything 
more than the Android encapper to produce the apk file. No need for 
android NDK, SDK or even JAVA to be installed ;-)


There are some glitches we are going to fix and than the encapper 
is ready for production.

Ladislav, couldn't you convert the docs to markdown into a file called 
readme.md so that they are visible by default?

You will get a driver.sys file that you can install, start, query 
and remove like this, from a Windows account with administrative 
rights:


sc create hello-Red type= kernel binPath= C:\full\path\to\driver.sys
sc qc hello-Red
sc start hello-Red
sc query hello-Red
sc delete hello-Red

	 append worker-args reform [" -cf" mold file] ]

and on line 123: all [ in uniserve/shared 'server-ports uniserve/shared/server-ports

However, when writing something like:

into a file, you may not be totally sure that somebody does not LOAD 
your code and try to evaluate it twice....

now getting this:

any experience running rebol-view on aws? looks like some libs/headers

Thanks for the welcome back message.
 

 I left off asking about the mySQL driver. So I want to insert into 
 a database a random number the code already generated and associate 
 it with an email address that was provided by a CGI form. Have yet 
 to create this in the real world but for now let us assume I will 
 call the database "customers". The people who process the credit 
 card and collect the email address advised me that the address will 
 be labelled "trnEmailAddress".


 After finding the mySQL driver Here is what I figured out using placeholders 
 for things like password, etc. Would appreicate knowing if this is 
 correct.

; Loads MySQL driver
do %mysql-driver/mysql-protocol.r
; Opens connection to MySQL server
db: open mysql://[[user][:pass]@]host[:port]/database


; Send query to database server. Enters random number from above. 
customers is probably the name of the database I will create

insert db ["INSERT INTO customers VALUES (?,?)" "trnEmailAddress" 
"token"]



 Next I need to insert an existing PDF file (an e-book) into a directory 
 created by the script. The directory will be named after a random 
 number that was earlier generated by the script. I am astounded that 
 I can not find the command to copy a file. So the variable assigned 
 to this random number is called "token".

 So I have the following.

make-dir %token/


 How do I copy a file into this new directory? Also, is that the corecct 
 way to make a directory?

guys ,i explained my mini project in database and game room ...they 
suggest me this room ! plz help me . my project is about one crossword 
which should show on web page !  i created html form and cgi file 
... when user enter value and press submitt it should save in database 
! my problem is i can not save value from form into database(MYSQL)... 
i am using mysql driver...i can make connectivity and retrieve data 
but i ca not save values ! plz guide me ,i do not have experience 
in REBOL... :(

Basically, you create an HTML file and put it on your webserver. 
Let's call it "form.html":


<form action="form.cgi"><input type="text" name="word"><input type="submit"></form>


Then you create a REBOL CGI matching the "action" used above, so 
"form.cgi", and also put it on your webserver:

#!/usr/local/bin/rebol278 -cs
REBOL []
cgi-values: construct decode-cgi system/options/cgi/query-string


;; Now you can access the "word" value submitted via the HTML form
;; as cgi-values/word.

;; Let's echo the value back to the user, as an example:
print rejoin [
  "Content-type: text/html" crlf
  crlf
  cgi-values/word
]

Yes, here is an example:
>> save/all %file.txt o context [a: self]
>> load %file.txt
** Syntax Error: Missing ] at end-of-script

file.txt file is:
#[object! [
    a: #[object! [...]   ;<---
]]

Caelum, SAVE/all and MOLD/all will have trouble saving your example 
object in a restorable state. The problem is those functions defined 
in the object, and bound to its fields. Those bindings won't be restored. 
For data that has to be saved and restored safely you're better off 
with having functions that operate on objects, rather than objects 
with functions in them. The "safely" part actually refers to not 
executing code, and you have to execute code to create functions. 
It's better to put your code in one file which you can protect, and 
your data in another file which you can be more wary of.

In R3, I want to be able to request a specific directory quickly 
and easily.  The easiest way I've found is to use REQUEST-FILE since 
it allows the user to quickly "navigate to" the desired directory. 
 Thing is, it requires the user to pick an existing file , even though 
I don't care about the file itself.  In most cases, this is fine 
since the user can pick any one of the files, but in cases where 
a directory is empty of a file, I have a problem.  

example code:

request-file/file to-file join "/" second parse what-dir "/"   <-- 
I use this to default the directory at the highest level is   ie 
 %/c  

Is there a better way to do this in R3?

I tried request-file in the android build, it didn't crash but nothing 
showed up. Not that I needed it - I was just curious.

I am trying to troubleshoot a peculiarity in   R3    2.101.0 from 
Saphirion

>> print type? what-dir

file!				<-- Ok, it's a file, even if has an end slash instead of 
a specific file path
>> print type? request-dir	; select any directory
file!				<-- Ok, Same thing


So it stands to reason that passing the value returned by WHAT-DIR 
and by REQUEST-DIR  will be FILE!

So here is my code that is giving me some trouble:

file-list:	[]

read-dir:	func	[
	dir	[file!	]
	] [
	foreach file read dir [
		file: either dir = %./ [file] [dir/:file]
		append file-list file
		if dir? file [
			read-dir file
	]	]	]

inp-dir: request-dir/path	what-dir 

unless inp-dir [ask	">>> No directory selected, cannot proceed  (Enter)" 
 quit ]
cd :inp-dir


read-dir inp-dir		; <-- does not work as expected, must use cd and 
what-dir instead
;read-dir what-dir
new-line/all file-list on
print mold file-list

Patrick, simple fix: if you expect INP-DIR do be a file refering 
to a directory, sanitise it through DIRIZE: `read-dir dirize inp-dir`.

The underlying problem indeed is related to a bug in R3. Both directories 
and files are represented by file! in R3. R3 uses a heuristic that 
a trailing slash discernes file file!s from directory file!s. Now 
when you pass a file! without a trailing slash but which actually 
refers to a directory to READ, READ crashes. (Bug#1675)

Back again.  Thank you Andreas,


I had realized that FILE! was used for both directory and files, 
but I didn't realize that REQUEST-DIR was NOT sending it back as 
a directory, but as a file (without trailing slash).  I was able 
to confirm by adding a print of WHAT-DIR and INP-DIR and compare, 
as per your comments.

I did not know about DIRIZE


Using READ DIRIZE INP-DIR does fix the problem -- though I wonder 
if REQUEST-DIR should return it with a trailing slash?

Thanks again to all!

Hello, someone needs Sublime Text 2 editor  syntax highlight file, 
see http://rebol.informe.com/forum/rebol-2-f8/sublime-text-2-t59.html
Do you know where he may find it?

Which script do you suggest me to use for parsing XML files for R'? 
There are many on rebol.org.

I mainly want XML to object, so I can export data from .xlsx file. 
XML to blocks might work but I may need to work on objects for more 
functionality.

for sure, you want stuff to be tag pair aligned so you can easily 
loop through it... though I don't know why he uses the file type 
to  mark tag content. 

probably just to differentiate it from attribute and tags

Endo, that's just his notation for a text node - not meant to imply 
it's a file.

a quick update on elasticsearch.

Currently I have reached 2TB datasize (~85M documents) on a single 
node.

Queries now starting to slow down but the system is very stable even 
under

heavy load. While queries in average took between 50-250ms against 
a 

dataset around 1TB the same queries are now in a range between 900-1500 
ms.

The average allocated java heap is around 9GB which is nearly 100% 
of the
max heap size by a 15 shards and 0 replicas setting.

elasticsearch looks like a very good candidate for handling big data 
with 

a need for 'near realtime' analysis. Classical RDBMS like mysql and 
postgresql

where grilled at around 150-500GB. Another tested candidate was MongoDB

which was great too but since it stores all metadata and fields uncompressed

the waste of diskspace was ridiculous high. Furthermore query execution 
times 
differs unexpectable without any known reason by factor 3.

Tokyo Cabinet started fine but around 1TB I have noticed file integrity 
problems

which leads into endless restoring/repairing procedures. Adding sharding 
logic

by coding an additional layer wasn't very motivating but could solve 
this issue.

Within the next six months the datasize should reached the 100TB 
mark. 

Would be interesting to see how elasticsearch will scale and how 
many
nodes are nessesary to handle this efficiently.

Or differently, has anyone worked with excel files via ODBC, using 
either R2 or R3? I tried Graham's code, which works for .xls files, 
but not .xlsx files. When I convert my file to .xls, R2 returns - 
not enough memory :-(

p: open [
     scheme: 'ODBC

     target: "Driver={Microsoft Excel Driver (*.xls)};DriverId=790;Dbq=c:\path-to-file\file.xls"
]
conn: first p
insert conn "select * from [Sheet1$]"
result: copy conn

I would write the structure as a dialect and sub-page generators 
from that. Each page would be a plain text file or a set of files 
which can be separately edited through a simple web interface.

I like the sencha guide page OK, but I like http://clojuredocs.org/quickref/ClojureCore 
better than the sencha API page. It seems like a better fit for Red/REBOL 
to me. Guess I'll really have to learn git now. 


Now, where is that new version of altme that uses git for file sharing 
and just hides all the details...

(in my file)

Error:

./r3-make -qs >NUL: ../src/tools/make-headers.r
.
 non è riconosciuto come comando interno o esterno,
 un programma eseguibile o un file batch.
mingw32-make: *** [prep] Error 1

Probably it is a missed file on your fork. I didn't build R3 on Windows 
yet. Cyphre can send that file I think.

Yes, I would like that as well.


For a proper solutation that avoids race conditions, it should create 
temporary files, not file_names_, though. So that would probably 
require a temp:// scheme?

using a scheme is a good idea.  then we can add various options to 
how to build them including things like auto naming, manual naming, 
prefixed naming, numbered, and the way it reports if a tmp file already 
exists.

>> file-type? %mi.txt
== text
>> file-type? %mi.r
== none


Text is considered a file type in R3, like .jpg and such. I think 
it was intentional, though I'm not sure whether we should continue 
to intend this. We should check with Carl.

for example, synchronous operations are just a hack, they fail if 
you try to download a larger file as there is a time limit to the 
whole operation.

Chris, the easiest way to do what you are trying to do is to use 
sys/load-header, which returns a block of the decoded header object, 
the position of the script after the header (after decompressing 
it if need be), and the position after the whole script (useful for 
embedded scripts. If the script is embedded in a block it will decode 
the whole script and return the decoded block at the position after 
the header, but that can't be helped. R3 scripts are binary, not 
text, so the returned script position is binary.

Note that it will skip past one trailing newline after the header,

Here's an example of that script-in-a-block embedding I mentioned:

In my dev, I have a central file for all of these.

Robert - do you mean IOS? I still think, that it was kind of superior, 
although it lacked cross-reblet API. Can you see all those Google 
drives, SkyDrives? Cross device, cross user file syncing could be 
done agas ago with IOS (/Services), if RT would have some product 
manager. Pity for lost oportunity. I still think, that something 
like IOS kernel/layer could or even should be used for OpenME ...

what exactly does mode do?

Any insights on establishing .r3 file associations on Windows 7? 
 Am I in the correct group for this?

Not exactly answering your question, you would need to check the 
r3_auto_file key in regedit, but the procedure is the same

Nonetheless, the plan was to have a user preferences system, with 
preferences persisted to a user-specific data file named user.r, 
in a declarative dialect (specifically no procedural code allowed 
in user.r). Unfortunately, that last sentence is as far as the plan 
got. We were going to have a community discussion about this, but 
hadn't gotten around to it yet because we're still too early in the 
development. Maybe now's a good time to start that discussiion.

I'm getting metaphorically killed by the FOREACH function blowing 
a system assertion 1207 periodically. I'm trying to process a couple 
thousand files and it's dying before it's finished. The script will 
need to be rewritten to call another R3 instance per file, just to 
make sure that it completes.

also, other option is to create CodeBlocks setup file so you can 
build directly from CodeBlocks using mingw but I guess noone did 
that so far ;)

Actually, to keep things as simple as possible for people, all you 
need is Code::Blocks, the CB project file and a slightly modified 
make-make.r that is soon to be checked in by Andreas (or which I 
could provide). Then, you can build from CB (and debug), navigate 
your C source propertly, etc.

Pekr, I don't think .RIP was meant for basic temporary compression, 
but a more fully fledged file format to store serialized REBOL data 
efficiently?

regarding zip versus rip - I can imagine runable zip - just add special 
file in it which would be used as a starter - actually that's how 
works for example APK, which is zip with different extension.

as far as i know, zip files allow prefix payload, so you can put 
stuff before the actual .zip file starts... just like REBOL allows 
stuff before the header.   I've seen a demo of a single file which 
is  an .exe,  .pdf ,  and .zip all at the same  time!

Old Bug, New Bug, Red Bug, Blue Bug?


I'm using the ARM build from rebolsource.net and getting the following 
unexpected behavior:

>> template: read %template.html


It outputs template as if it was a binary file, although it is plain 
text.

The build date on the package was 24-Jan-2013.

The ZIP format is supposed to be like a directory/file structure. 
I would rather have it supported as a zip:// port scheme, like file:// 
is for files and directories.

BrianH, yup I realized how it works now and I even fixed the /gzip 
quirks in DECOMPRESS...so I can decompress zip chunks with CRC32 
checksums now. But there is still one annoying bug, that the current 
zlib code doesn't handle the CRC32 calculation well on bigger files 
than 32kB :-/ Now I'm trying to fix it so the crc32() calls works 
in the "CRC running" mode where the final CRC32 is calcualted from 
smaller chunks of data which a file consists of.

I'll hopefully push this on github If I manage to fix it succesfully.

How about writing to a file and sending to the port and seeing if 
there's a difference ...

So better just file a CC issue for the `browse none` crash, and we 
can discuss the desired design in there.

Marc, did you file a ticket for this? If not, I can repurpose #1921 
for this.

Hopefully one remembers having marked a file with --assume-unchanged 
when actually _trying_ to stage changes from that file :)

In rebol 2.7.8.3.1 the #884 version has the same "strange behaviors" 
as the one that Gregg posted as a file here.

I have an updated SPLIT-PATH, modeled on Ladislav's implementation 
where it holds that

   file = rejoin split-path file


This does not match current REBOL behavior. His version arguably 
makes more sense, but will break code in cases like this:

	%/c/test/test2/ 
	REBOL      == [%/c/test/ %test2/]
	Ladislav's == [%/c/test/test2/ %""]


Ladislav's func only seems to go really wrong in the case of ending 
with a slash an that's the only slash in the value which return an 
empty path and entire filespec as  the target.

Schemes (http://) don't work well either.


REBOL also dirizes the file path if it's %. or %.., which Ladislav's 
does not. e.g.

	[%foo/ %../]  == split-path %foo/..

Anton, which is the behavior question. Do you expect SPLIT-PATH to 
return a target you can write to (i.e. a file)?

I haven't had the time to follow all the discussion in detail, but 
to me, the second part of split-path should NEVER return a directory 
path. 


when doing   set [dir file]  I should be able to count on the fact 
that the second part is either a file or none.  The same for the 
first part which should always be none or a dir.  I have my own implementation 
in R2 which makes this strict and it simplifies a lot of code.
so we can do with absolute certainty:

if second set [dir file] split  path [   ]


IIRC some of the versions of my split perform a clean-path to simplify 
and add robustness to the result.

Re:

%/c/test/test2/ [%/c/test/ %test2/]


- this test does not violate anything but it does not split the "pathfile" 
to "path" and "file" parts

Regarding the split-path behaviour in the %foo case. I stongly object 
against the proposal to obtain [%. %foo], since for example INCLUDE 
whan obtaining %foo with empty path uses INCLUDE-CTX/PATH to find 
%foo (which may even exclude the %./ directory if it is not in INCLUDE-CTX/PATH), 
while when obtaining %./foo it just finds the file in the current 
directory (which is not equivalent)

As said, I prefer [%"" %foo] to have the invariant that file = rejoin 
split-path file

question is, is that invariant useful? 


really, I like consistency almost above all else, but I prefer when 
it not just neutral.   getting empty file specs is very awkward to 
use and doesn't work well with all the none transparency which makes 
a lot of the conditional code so easy to read.  one reason this is 
so readable in REBOL is the limited use of equality operations, when 
doing complex decision making.

I prefer

split-path %foo
== [%./ %foo]


The reason is because I believe split-path shouldn't require an extra 
check if all you want to do is read the base directory that a file 
is in.  I think this is a common use of split-path.

Do our preferences come from the basic difference of whether we want 
SPLIT-PATH to be "smart" about file specs, or whether it should assume 
nothing (the REJOIN invariant case)? For example, Andreas's path 
invariant (p/:t) makes a lot of sense, but some of his examples' 
results look wrong when just viewed as results. e.g.:

;   %/              [%/ %/]
;   %//             [%/ %/]
;   %./             [%./ %./]

And while I understand that a file with no path implies the current 
directory, we lose information by assuming it. For example, if I 
let a user specify a path or filename, and I split it, now I can't 
tell if they gave me just a filename, or if they gave me %./<file>.

we have got quite a few combinations to consider:

missing path:

* yielding %.
* yielding %""
* yielding #[none] 

missing file

* yielding the last directory in the path
* yielding %""
* yielding #[none]


In total that is 6 variants but only some combinations make sense, 
I think

It could only do that in relation to a file system or with the simple 
heuristic used by DIR? as well: based on the presence of absence 
of a trailing slash.

Isn't a convention that %foo/ is a directory while %foo is not?  
That's one way to tell if a given file! directory or not...  It's 
what I generally expect, and I agree with Maxim that it makes the 
most sense for split-path to return #[none] if there is no file.

It can't do a check, because the file may not exist.

Max said: "split-path shoudn't invent information which isn't given 
to it"


I agree, if we consider split-path to be operating in string mode 
(the rejoin invariant). If we want to have a file-system aware option, 
what would we call the refinement? Or should it be a separate function?


As far as returning none for either part, it strikes me as inconsistent 
(if convenient, which it may be). That is, if you split a series 
into two parts, splitting at the head or tail should just give you 
an empty series for that part, shouldn't it? This comes back to my 
SPLIT-AT question.

Hi, I'm reading the REBOL3's source codes, and I don't know It's 
a typo or not: in this file https://github.com/rebol/r3/blob/master/src/include/reb-c.h
at line 61, about defining the uint type, It seems #ifdef DEF_UINT 
 was not correct. Maybe #ifndef DEF_UINT ?

Bundle scripts along with the rebol executable, for distribution, 
as a single file.

Just so happens that I have a CB project file for the official source 
layout, if you want it. There's also a little change to make-make.r 
that you'll need t make for which he's made a pull request.
