willghatchjgart what i expect is a barebones programming experience(without third party libraries/ tool kit) to learn logic & problem solving ( like project euler) & text processing, scripting for regular system tasks, good knowledge about database fundamentals & algorithms for programming and may be reading some real world project codes later, if possible.I am not keen in mobile app, webpage creation. my kid age is 12, but he doesnt like scratch... would dr racket fits here or scheme only?

I'm not the OP, but I'm having the same problem. I don't see libedit.dll in my Racket 7.9 installation. (Unlike the OP's error message, my system does not find libedit.dll and not libedit-3.dll.) My Windows 10 system is version 2004 build 19041.388.

Instead of trying to fill in libedit.dll, I will try readline. So I install the package first.

Now I try to run it from cmd.exe.

C:\Users\x\AppData\Roaming\Racket\7.9>rash-repl.exe ffi-lib: couldn't open "libreadline-5.dll" (Não foi possível encontrar o módulo especificado.; errid=126)

That's just Portuguese for "The specified module could not be found.; errid=126)".

Put libreadline-5.dll in the same directory as rash-repl.exe.

C:\Users\x\AppData\Roaming\Racket\7.9>dir libreadline-5.dll O volume na unidade C é X O Número de Série do Volume é 80B6-21C4

Trying to run, I get: C:\Users\x\AppData\Roaming\Racket\7.9>rash-repl.exe ffi-lib: couldn't open "libreadline-5.dll" (%1 não é um aplicativo Win32 válido.; errid=193)

This means "%1 is not a valid Win32 application; errid=193". I must have the wrong DLL for my system or something like that. I downloaded it from

http://gnuwin32.sourceforge.net/downlinks/readline.php

I suppose you wouldn't know what to do here? Thank you.

Sorry, I don't know. I'm afraid I don't have time right now to try to figure it out either. I don't use Windows, so it's harder for me to debug than Linux. My long-term plan is to replace the readline dependency completely with a line editor written in Racket. But I won't be able to do that terribly soon either since I'm busy teaching and wrapping up my PhD.

Though I feel that I should note that I can't really recommend Rackterm. It was my first real Racket project, and was more to learn Racket than anything else. I would like to return to it some day, give it a hardware accelerated renderer frontent (its rendering is super slow and CPU hogging), a nice screen/termux-like frontend, make it nicely configurable, etc.

But it's much less of a priority than Rash, and there are several sufficiently decent terminal emulators. I'm afraid I didn't dogfood Rackterm very long.

PING... Any news regarding the Rash2?

I'm sorry, I thought I had replied to this.

There isn't actually a repository for Rash 2 right now. Rash 2 is really just a list of things that I'm not satisfied with in current Rash that to fix would be a backwards incompatibility.

Before I ever start a real Rash 2, there are a lot of improvements that I have planned that are not backwards incompatible (eg. improving stuff that is currently undocumented or explicitly documented as being unstable). When I do write a Rash 2, it will probably be a fork where I just fix all of those things. In particular, when I make a Rash 2 it will have much more thought about the default set of operators, naming conventions, etc, that I chose somewhat hurriedly to get something out the door. Rash 2 will be an opportunity to revisit those decisions with more experience and less haste. Rash 2 will (when it exists) be a separate Racket package so all old scripts will still work.

Unfortunately, I'm just busy with other things and don't have the time and energy to really push Rash forward much right now. Grad school is busy and stressful. I wish I could work more on Rash right now (frankly, I care much more about Rash than my other projects), but I really need to push on other things to graduate.

No rush :) just a little bit of pressure from over here :) Anyway thanks for a prompt answer.

What do you people write code in? I wanted to return to programming some more in Racket but have few issue with my Emacs setup.

My first problem is with completion (I use company-mode) normally as soon as I start typing (after 2 characters) I would get a companay pop-up with suggestions, in racket-mode instead of that I get a weird behavior in message buffer which looks kindof like a weird completion mechanism of it's own.

Second issue is that I tried to get automatic documentation in message buffer after I move my cursor onto a function call. I tried to enable eldoc back but I get "function definition is void" error.

In reply to @xgqt:matrix.org
welp, I'm spoiled and would like my auto-completions :P

I believe the problem I have is that rash-repl.exe is a 64-bit application and I can't find a 64-bit version of readline. I believe we cannot mix two architectures in the same program.

--8<---------------cut here---------------start------------->8--- %file rash-repl.exe libhistory8.dll libreadline8.dll rash-repl.exe: PE32+ executable (console) x86-64 (stripped to external PDB), for MS Windows libhistory8.dll: PE32 executable (DLL) (console) Intel 80386 (stripped to external PDB), for MS Windows libreadline8.dll: PE32 executable (DLL) (console) Intel 80386 (stripped to external PDB), for MS Windows --8<---------------cut here---------------end--------------->8---

Since I cannot find a 64-bit application, would it be much trouble for you to compile rash-repl.exe as a 32-bit application? I believe this would take care of things for me and, therefore, for practically all other Windows users --- having this exact issue.

But I know you're busy. If this is not just another command for compiling this desired version, don't worry about it. I can manage to eventually compile the right library version for the right architecture.

Thank you either way. I'm insisting because I think the software is great. I read your paper carefully in the last couple of days. Thanks for writing it.

Just a tiny improvement

My rashrc contains:
#! /usr/bin/env racket
;; emacs - set major mode: SPC h M racket-mode

(displayln "=== Loading rashrc")

;; rashrc is NOT a module, and gets none of them. rashrc is mainly there to let
;; you muck up the namespace that you use interactively. Prefer rashrc.rkt
;; @secref["Interactive_Use" #:doc '(lib "rash/scribblings/rash.scrbl")]
(current-repl-display-startup-hints? #f)

(define-line-macro f
(lambda (stx)
(syntax-parse stx
[(_) #'{echo "foo"}])))

and rashrc.rkt:
```racket
#lang racket

(displayln "=== Loading rashrc.rkt")

(require
 linea/line-macro
 (for-syntax syntax/parse))

(define-line-macro b
  (lambda (stx)
    (syntax-parse stx
      [(_) #'{echo "bar"}])))

The line-macro f works but the b does not. Does anybody know why? (My racket-fu is too young. Sorry guys)
