SciTE-st Release 6


Hey everyone,

This is the packaged release of SciTE-st. No more jumping through
hoops to download dependencies, copy them to places, make sure
platform variables are set, etc. All of the files are in one place and
hopefully you'll just be able to unpack the archive, move it to an
appropriate location, and run the executable with everything working
right away.

As always, please read the documentation. Links are on the
http://caladbolg.net/scite_st.php website.

Scintilla and SciTE have been updated to v1.75

Windows: http://scite-tools.googlecode.com/files/scite-st_win32_r6.zip

Linux: http://scite-tools.googlecode.com/files/scite-st_linux_r6.tgz

Note you still have to install the Linux version to /usr/share/scite-
st or recompile.

editor:textrange() accept C-array indices, so sele is
editor.Length - 1 and the second argument is also an index. The
following works for me:

function escapeString()
  local sels = editor.SelectionStart
  local sele = editor.SelectionEnd
  if sels == sele then
     sels, sele = 0, editor.Length - 1
  end
  local text = editor:textrange(sels, sele)
  local out = string.gsub(text, "([\"\\\'])", "\\%1")

   This is going to be quite a lot of work no matter which approach
you take. The best long term approach is to avoid transferring to the
tool thread at all when performing a Lua function but you'd have to
understand the execution mechanism thoroughly before working on this.

Tracker group


   There is a new scintilla-tracker Google group for receiving
Scintilla and SciTE bug reports and feature requests from the trackers
on SourceForge. Unlike the old system on lyra.org, this is separate
from scintilla-interest and scite-interest so only those interested
will see the issues. If you want to respond to an issue, it is best
done on the tracker where it is most likely to be seen by the
initiator.

Re: SingleThreadExtension.cxx


I think I am getting there, but I might be wrong (again). It turned
out amazingly simple, so I am suspicious, having very little
experience with threads. With unpatched SciTE 1.75:

1. I define a keyboard trigger for a Lua function that calls a dll
function.
2. The dll function starts a tool thread passing a pointer to
dynamically allocated resources (a string) to it, closes thread
handle, and exits.
3. The tool thread:
- initializes COM,
- creates a server instance, makes the call, cleans up, uninitializes
COM, and
- deallocates the pointer to the parameter string.

No synchronization between threads, because it is a one-way trip. If
the tool thread fails, it fails silently.

I chose this somewhat strange approach of creating the server instance
each time, because it makes the dll less "stateful". It does not seem
to cause any slow-down, but I don't know about heap-fragmentation-like
longer term consequences.

I'll post my code when it is more complete (in 6-7 hours) if it is ok.
Thanks again,

Maciej.

   So you are not expecting to call anything that returns a value.

   I don't think the Filerx author is active any more.

Lua extension libraries compiled against SciTE for Windows


Hi guys,

I've put up exts.zip, which is a sampler of useful Lua extension
libraries recompiled against SciTE.exe.  It contains lfs.dll (the Lua
filesystem), bit.dll (bit operations) and luasocket. Just unzip this
in your SciTE bin directory.

luasocket in particular gives your scripts interesting new powers,
like the ability to send email ;)

Or (probably more useful) the ability to push stuff onto ftp sites.

I didn't feel it was necessary to do this for Unix/GTK, because the
regular .so files will work fine, if your package.path and
package.cpath are set properly.

ok, that's working also for me, thank you.
