Because writing one that is usable and complete requires a *lot* of

Hmmm... if I recall correctly you mentioned one of the advantages of
using F# is its IDE (Visual Studio?). In fact code-completion seemed to
be one of the functionalities you pointed out as useful. Well, OcaIDE
has this. And much more. I figure if you believe a full blown IDE for
F# is advantageous, then it should also stand for Eclipse, Netbeans,
or any other IDE.

Mind you, I assume your "horrendous" may also have something to do with
the plug-ins quality. I believe OcalIDE is quite usable at this point in
time. So.. try it out. Join the forum and give you feedback.

BTW, I am harping on this issue because I truly believe that a good IDE
is an excellent medium for promoting the use of Ocaml.

Hello,

Indeed it's a lot of work and I wish I had more time to work on it.
Here are some comments about my experience developping Chamo[1].

It's important for me to be able to change the editor/IDE I use without
having to change the build process or the organisation of the source files.
It's kind of easy to force the developper to use some tools and the way to
use them, saying "If you use my wonderful editor, you have to put your code
here, use this tool and not this other, etc.". The hard part is to keep
flexibility and so to foresee what must be customizable by the user. And
this flexibility is required to be able to contribute on projects using
different organisations and build processes.

For this reason, I never developped a "project manager" in Cameleon,
because I did not want to put my includes and other flags (for example) in
a specific file and become "cameleon-dependent" (and so for the possible
contributors). So I keep on writing Makefiles.

(Chamo is part of Cameleon. Cameleon aimed at being an IDE, with
documentation browsing, version control, etc., and using Chamo as
default source code editor)

So my recent efforts were on Chamo, a source code editor, like emacs but
written in ocaml and using ocaml rather than elisp to write configuration
and extensions. Again, the difficulty is to foresee what the user will want
to change because in ocaml a function f cannot be *redefined*: it is
possible to define *another* function f, but functions using the first
definition will continue to use the first definition, not the new one. So
I added "commands" in Chamo, like shell commands. These are only names, and
the user can change the ocaml function associated to these names. This
allows the user to write the ocaml code which calls its favorite tools and
to for example bind this code to the keyboard shortcuts he wants (see
examples at [3]).

The GUI represents a big part of the work, even using an existing source
code editor widget (gtksourceview). There is a lot of information
to keep and display, a lot of things possibly happening. Moreover, as
soon as there is interaction with the user, error handling is required at
every line...

For ocaml-specific aspects:
- Chamo uses .annot files to display type information (Alt-t),
- ocamlbuild is supported,
- errors messages in compilation processes (ocamlbuild, make or any command)
are parsed and the cursor is positionned at the location of the error.

So I already use Chamo for my daily work (development, edition of text
files). What's missing now is access to more information like location of
definitions, completion and so on. I'm waiting for the result of
ocamlwizard[3] to see how to use these tools in Chamo to provide these
missing features.

Since these tools will surely need some information about compilation
flags, there are two solutions:
1. Add a way to indicate these flags to Chamo/Cameleon, but keep this way
flexible so that any user can import them from any other location
(makefile, etc.)
2. Use "dump" files to store the results of these tools and Makefile targets
to produce them (that the way ocamldoc is used in Cameleon for browsing
documentation)

Intellisense-style completion would be incredibly productive, particularly in 
the context of GUI programming but note that doing this for LablGTK2 would 
require the system to have used type inference and type annotations on the 
structurally-typed objects in the source code to determine the type of the 
start of an expression in order to propose completions for it.

I have found -dtypes to be very slow on large code bases and I assume this is 
because it generates such huge dump files. Perhaps this could be optimized 
somehow?

No. I just donwloaded it and indeed it could be used from chamo to provide
some more features in a flexible way.

Indeed. By the way, I'm not a big fan of completion, I prefer to use/train

Chamo uses .annot files produced by the compiler when the -dtypes is
specified. If the expression has a type indicated in the .annot file, than
it is displayed, else no indication is displayed. If the source file has
been modified after the .annot file was created, then a message indicate
that the current .annot file is obsolete and must be updated by compiling
again. This is the same behaviour as under emacs.

Definitely.  .annot files are incredibly bloated.  Here's a snippet
from a .annot file I have on my hard drive:

"""
"ra_live.ml" 342 11092 11107 "ra_live.ml" 342 11092 11117
type(
  Ra_type.code_class
)
"ra_live.ml" 343 11121 11139 "ra_live.ml" 343 11121 11147
type(
  LiveSet.t
)
"ra_live.ml" 344 11148 11172 "ra_live.ml" 344 11148 11177
type(
  Ra_type.label
)
"ra_live.ml" 344 11148 11163 "ra_live.ml" 344 11148 11177
type(
  Ra_type.code_class
)
"""

See any opportunities for optimization?  ;^)

In fact, gzip does a pretty fine job of optimizing .annot files.  The
source file this .annot came from is 15K, the .annot file is 78K, and
gzipping it gets it down to 9K.

Tokenizing that .annot format by simply mapping each string onto a unique 
token and writing out the mapping first will shrink such files enormously 
whilst still being easily dissected from any language. Moreover, the benefit 
is super-linear...

Sure, I had the same thought, but gzip already exists, doesn't require
approval from INRIA, and .gz is easily read in just about any language
(including OCaml).  Once the .annot files are smaller than the source
files I'm completely willing to generate them all the time.

I think you will find that GZip is orders of magnitude less efficient that the 
approach I suggested and too slow to be useful in this case.

For example, gzipping and unzipping the .annot files from the 4kLOC core of 
Smoke takes 0.5s. So GZip is too slow for interactive use even on this tiny 
code base.

Why would you want to unzip more than one .annot file during
interactive use?  If I query the type of some token foo in bar.ml I
only need to read from bar.annot.gz, not all the files in the project.
 The biggest .annot file I have lying around is from a 40KB source
file.  It's about 270KB before gzip, 30KB after.  According to "time"
it takes 0.009 seconds to gunzip on my MacBook Pro.  I'd say that's
plenty fast enough to be useful, even if your machine isn't quite as
snappy as mine.

I don't dispute that a more efficient encoding than gzip can be found,
but good luck convincing anybody at INRIA to work on it.  ;^)

As the guy who implemented one generic form of "throwback" for NEdit,
namely calltips, I can tell you that it certainly does support it and
I've used it extensively.  It's an editor that is extremely flexible
without being *too* obscure, so you can get it to do just about
anything you want.  I have been unable to find another editor that has
the same combination of power, flexibility, and ease-of-use, and I've
looked far and wide.

Having said that, I'm afraid NEdit development has sunk into a tar
pit.  There is no effective leadership on the project and it's
inextricably tied to the Motif toolkit, which means very few new
developers will sign on.  I've given up and switched to jEdit, which
has a similar spirit (platform-independent, language-independent,
flexible) but, being written in Java, a much higher bloat factor.  But
hey, with 2GB of ram it doesn't feel so bad to give 150MB to my text
editor any more.  I would *love* to have an alternative written in
OCaml, since my forays into the jEdit code have left me with
unpleasant feelings...

They tried, indeed (I'm kind of helping in that projet, so I'm aware of
the progress). Unfortunately, even with the CVS version of Ocaml, the
.annot files appear to lack some information. But the solution currently
followed by Ocamlwizard is along the lines of .annot files, and may even
rely on these files in future version of Ocaml.

Indeed.

On a related note: what would people recommend as a good OCaml source code 
editor under Linux for someone who finds Emacs too archaic and Eclipse too 
slow?

Are there any other editors with type throwback (and maybe even error 
throwback)?

Actually, as a regular Emacs hacker myself, I checked out .NET's F# 
environment and I must confess that I was quite impressed. It is 
actually really neat. Instead of the usual edit, M-x compile, M-x 
next-error cycle, the code is compiled in the background creating 
"squigglies" under code that has errors. Using this and the 
Intelli-sense completion features is very nice and I wish we could have

hey! this thread its animated!!! i think its possitive to think about
develop an exclusive Ocaml IDE, why??:

- novice people on ocaml will found all easier.  ->  so more novice people
will be interested in ocamle  -> so more ocaml developers become active ->
ocaml community will grow up!

The intention of developing a NeTBeans plug-in is provide pupils of my
univesity a friendlier interface, 2 years ago myself cursed the subject
where ocaml was used, and i found difficult learn a new paradigm, 	
and if we add to this that in labs teacher say , "ei! you have Caml
installed, start programming!"...

I think this plug-in could be a starting point for future more friendly
interfaces for developing, so why not??
of course at this point, the plug-in its very simple, syntax highlighting,
auto completion of code, and link with external compiler,but...this is  only
the beginning....

Agreed. That is precisely why I think it is a bad idea to build upon Eclipse.

However that is not an inherent property of an IDE. Surely one written in

The Scala plugin for Eclipse is also almost unusable. AFAIK, Haskell has 
uniformly poor support in this respect as well. F# is the best of the 
functional languages but still leaves a lot to be desired, IMHO.

Actually, many OCaml programmers gave the F# team positive feedback over their 
Visual Studio mode precisely because it makes experienced users so much more 
productive.

That is exactly what I do when writing OCaml at the moment and I find that it 
leaves a lot to be desired.

For example, I cannot even jump to the definition of an identifier reliably. I 
can look at the identifier and guess where it came from, potentially having 
to manually trawl through directories of source files exactly as you 
describe, hoping to find the correct location from many identifiers with the 
same name. But it would be much easier if I could simply jump directly to the 
location of the definition and then jump back. That could be done from plain 
text editors.

Exactly! This is the reason why I sent the e-mail to this list in the

contribute to it.

I guess if the IDE was written in OCaml he would be an active

Personally I find Eclipse appalling. It takes forever to start
up and runs slow as a dog. It might support Java reasonably well
but I find its support for C rather poor. I haven't tried it
with other laguages.

I didn't mention having tried Eclipse before because I really
only used it for a couple of hours.

I spent 35+ hours/week for 6 months on VS2005. Is that not enough
time to learn it?

But the Adobe IDE was definitely different to the VS2005 one I 
was using a couple of months earlier. What I really wanted was
to be using my editor, with my personalised syntax highlighting
pattern and my macros.

> Granted. But I am defending lowering the barrier for Ocaml use.

If you are advocating IDE use for the purposes of making Ocaml
easier for newcomers then you are in a bit of a bind. The 
people who need the IDE are the newcomers who are not capable
of writing one and the ones with sufficient experience to write
an Ocaml IDE are happy with what they have and are therefore 
not interested in writing one (with the possible exception of
Jon Harrop).

It's amazing how you criticize the lack of this or that in the community, but 
are reluctant to help it.

I guess the IDE you mentioned at first place would have been a non-commercial 
software under some sort of open source license, so why this limitation when 
you *may* contribute.. ?

There are ways of getting this to work with nedit but I never

If I need documentation I read the mli files. With bash command
line completion in an xterm I can find the one I want in a second
and I keep it open in a nedit window and then alt-tab between the
window I'm editing and the mli file I'm reading. Sometimes I stick

You sound like someone who never mastered Unix, someone who never

than accepting what Unix provides as a default.

Ok, I assumed too much then. My apologies.

Two comments though:

a) Don't expect an IDE to provide all of the underlying functionality.
    Its just not feasible. I don't expect it.

b) I am *not* saying that IDEs don't have limitations. I am defending
   the point of view that a good IDE will *promote* Ocaml's *adoption*
   (ease of use for newbies, facilitates giving classes to students,
    allows quick prototyping by *non-experts*, etc...)

What I say here also goes for Richard. I am aware that a lot of time
has gone into learning these tools (20 years!). I am just saying that to
use IDEs also requires effort. Of course whether this is advantageous or
not is up to you. For the newbies, students and even those that hack
as a hobby, I believe it certainly is. This is what I defend.

Granted. But I am defending lowering the barrier for Ocaml use.
Not for solving every conceivable problem that comes your way.
Remember: use the right tool to solve the problem.

Ubuntu, before that Gentoo, before that Fedora, before that Red-hat.
Ok so before that windows NT, VMS, windows 98, windows 95,
windows 3.1 (I think), and ms-dos. So yes, I used windows quite a bit
;-).

On a final note: I believe that much of the resistance to use IDEs
also comes the following simple facts:

a) A lot of effort has gone into learning the tools used. No one wants
   to throw away all they have invested in that.

b) Use of an IDE may also signify "lock-in".

But please note: I didn't say use only the IDE. That's not possible. We
all know that. Again, I am only defending the idea that IDEs are
excellent to facilitate the use of Ocaml.

Function signatures is one thing but the ocamldoc comments are at least as

Yet Make is not expressive enough so we have OMake, OCamlBuild...

That's great but it is the writing of OCaml code that is unnecessarily

I assume nedit does not even have basic type throwback, let alone 
documentation throwback?

Diversifying to Windows has certainly shown me just how far behind Unix is in 
terms of usability, productivity and modern computing environments like GUIs.

Here is an example: programming the GUI Sudoku solvers in OCaml and F# for the 
OCaml and F#.NET Journal articles. I had years of experience with OCaml but 
little experience of LablGTK2 (I did not know its API at all). I had little 
experience with F# and none with Windows Forms. Yet I wrote the F# 
implementation 10x faster because the Visual Studio mode makes it trivial to 
explore unfamiliar APIs with complete graphical throwback of documentation. 
In contrast, developing the OCaml required me to use "grep" to search the 
LablGTK2 source code distribution from the command line and ocamlbrowser to 
find definitions (but there is no way to jump to related definitions and no 
way to jump back to previous definitions). That is unbelievably tedious in 
comparison.

Provided you only want to write programs that manipulate text and maybe do 
some custom OpenGL, OCaml is awesome. But if you want to write even the most 
mundane GUI application, OCaml is a world of pain compared to the 
alternatives. This could be solved by a decent graphical development 
environment.

Mathematica has by far the best GUI I have ever seen. I think it would be 
fantastic to have such an interface available for OCaml but, as I say, the 
front-end requires tight bindings to the compiler and top-level which is not 
easy with OCaml.

As little as a 18 months ago I spend about 6 months maintaining
100k lines of mixed C++ and C# code using Visual Studio 2005,
the IDE all the IDE fans rave about. It found the Visual Studio
experience amazingly underwhelming; beyond tedious. The GUI hid
details from me that I thought I needed to know and got in my

More recently I spend a couple of months using the Adobe Flash
GUI development tools. Again I found this a woefully tedious
exercise and wished for command line tools to replace the stupid
and annoying GUI. The GUI thought it knew how I wanted to format
my Actionscript code better than I did.

The funny thing is that my preferences for command line tools was
something I developed after my first exposure to an IDE. My first
serios coding was done on Borland's Turbo Pascal and Turbo C IDEs
back in the late 1980s.

In the late 1990s I did a lot of FPGA development using the Xilinx
development tools. It was the inadequacy of these tools which forced
me back to Make because my Makefile understood the build process
I wanted to achieve better than than the Xilinx tools. Later on
in my FPGA design career I would do schematic entry of FPGA designs, 
export a Xilinx XNF netlist, convert the XNY netlist to VHDL using
a utility I wrote and then run that VHDL through a simulator.

This was actually a pivotal event for me because I was able to do
better work by breaking free of the IDE which limited what I could
do.

IDEs still limit what I can do. How many IDEs allow for meta

code which gets compiled to create the final program?

How many IDEs cater for more than one language? The thing is I use

How many people who use multiple languages are willing to learn a

The same can be said for the Unix IDE, but the UNIX IDE is 100
times more flexible and more capable than any other IDE in
existance. I know Make well enough  to whip up a complex make
file in minutes. I am also intimately familair with the automake/
autoconf/libtool set. Since these tools are so flexible they
adapt to my requirements and never force me to work the way they
are designed.

I don't like emacs and vi. My editor of choice for the last 13
years has been nedit (Nirvana Editor) which has syntax highlighting
for dozens of languages (and it easy to add new ones or modify
existing ones), regex search/replace and macros. Its configurable
so over the years I have bent it into the shape I  want. The same
goes for my Unix shell.

> Why should the use of an IDE be any different?

Unix is my IDE and I am reasonably certain that I can do more
with my IDE than you can do with yours :-). By more, I mean
more languages, more meta programming, more custom build
options with more languages.

I suspect that a lot of the people who think Ocaml needs an IDE
are people whose primay development platform is windows.

You miss the point that most Unix programmers already know emacs or vi
intimately.  I use emacs constantly -- even for writing this very
email, and I have been using emacs for nearly 20 years.  No
"mastering" is needed.

I've used IDEs a bit, but never particularly saw the point.  They seem
to just obscure the workings of the build process, and break the
editor, for no tangible gain.  Emacs can already print the type of an
expression when you hover over it, and can autocomplete symbols.  I've
to find an IDE that can edit email.

There are many problems with the Unix build process -- eg. the horrors
of autoconf/automake/libtool, and possibly better integration with
packaging.  Lack of an all-in-one graphical tool is not exactly high
on anyone's list.

I'm sure you know why, but because (a) it's a huge amount of work and
(b) the sort of people who can do the work already use emacs so they
don't need it.

It'd be better to concentrate on OCaml for Eclipse (& other IDEs).
OCaml has the parts already to make an excellent Eclipse plugin -- eg.
camlp4, ocamldoc, cmigrep and '-dtypes/.annot'.  If Eclipse itself has
specific problems, then fix those.

Red Hat have done a bit of work packaging and fixing the OCaml Eclipse
plugin and we'll have something to release soon(~ish).

I am sceptical of comments such as those of Erik's (no disrespect
intended here). I suspect these people either have not tried using
an IDE or simply haven't made the effort to learn to use the IDE and
take full advantage of it. Which is surprising since mastering Ocaml
requires much effort, and all here seem to agree that the added
productivity of using Ocaml is worth it ;-). In fact mastering
emacs, vi, etc. with all those "modes" also requires a lot of
work. Why should the use of an IDE be any different?

Jon, I would really be interested if you could report back on your
experiences.

I am not sure how it was done in OcalIDE but we have full function
signatures (we need only hover above the function). I guess if parsing
is done via another tool this would not be a problem. Could ask
the OcalIDE folks how its done.

Graphical throwback of documentation is invaluable for interactive API 
exploration, particularly in the context of GUI programming (I currently 
trawl through ocamlbrowser's useful but very basic interface). A GUI to 
browse and visualize performance profiles is useful (I currently browse 
gprof's output as plain text files using KWrite). A GUI to visualize 
dependencies is useful (I currently lookup the use of "dot" every time I need 
it and the PostScript output is typically mangled by GhostScript).

I shall see if it is feasible to develop such an application within an OCaml 
Journal article or two. I think it would be both very useful and a very 
instructive educational exercise combining several of OCaml's strengths.

However, the resulting program would most likely be difficult to distribute 
due to licensing issues (e.g. if you want to reuse OCaml's typechecker or 
top-level) and could not be a viable commercial product due to the 
limitations of OCaml itself.

Most people who actually code in Ocaml do so using the best IDE on
the planet, Unix. For those people an IDE is a step backwards and
hence they have no interest in writing one.

So I have an idea; why don't *you* write a cross platform IDE and if
it really is better than Unix then people would use it.

If I might stick my oar in: why don't the OCaml community write an IDE for 
OCaml in OCaml using Camlp4 for parsing with throwback and LablGTK for the 
GUI?

This has long since seemed like an obvious idea to me but everyone continues 
to battle on with tools like Emacs and Eclipse that are (IMHO) horrendous.

Hi Adonis28850,

I don't know if you are aware of this but IDE support for Ocaml already
exists and is quite mature. Support is in the form of an Eclipse IDE
plug-in. I don't know what your objectives are, but this may be what
you're looking for. Note that I use both Netbeans and Eclipse so an
Ocaml plug-in for Netbeans would also be welcome.

For everyone else: use, test and contribute to these efforts if you
can. A lot of effort has been put into them. Some previous attempts
have "died" due to lack of support.

Please note that I am a simple user and not in any other way associated
to OcaIDE, however please take a look at:

http://ocaml.eclipse.ortsa.com:8480/ocaide/

It includes among other things:
     * Source editor for ml, mli, mly mll files
     * Syntax coloring
     * Automatic indentation
     * An integrated code formatter, and an interface to the camlp4
formatter (through an AST printer)
     * Code Completion
     * Standard library browser
     * Integrated debugger
     * Highlighting of matching delimiters
     * Integrated toplevel
     * Building of O'Caml projects
     * Importation and exportation of O'Caml projects
     * Launching of O'Caml executables
     * A code outline
     * Displaying the inferred type of elements in the editor and outline
     * Descriptive popups on O'Caml definitions
     * Help on expected parameters for functions, exceptions and
constructors
     * Hyperlinks for jumping to the definition of an element (variable,
type constructor...)
     * Error markers in the editor, editor's margin, Navigator view and
Problems view

Regards,
Hugo F.
