According to 'requirements' tclreadline works with at least some versions of tcl8.4. I struggled to build tclreadline 2.1.1 on FreeBSD5.1, against tcl8.4.6 only to get a core dump when running ::tclreadline::Loop
I've also tried using rlwrap, which does not appear to run on FreeBSD4.9 and which complains "could not open master pty" on my FreeBSD5.1 box.
Seeing as I really only want the basic up & down arrow cycling through history, and not the fancy readline search & autocompletion and whatever else it may offer - is there some other way I can achieve this functionality in a plain tclsh shell? (I need to run this on plain X-less boxes and ssh sessions.)
It seems to me a very unfortunate lack of cross-platform consistency that the functionality I've always taken for granted on windows boxes doesn't seem to work on Unix-like machines. I understand the gnu readline license is unsuitable for inclusion in TCL, but is there no interest in including some *basic* history editing in tclsh to bring it into line with Windows behaviour?
NEM When you say it works on Windows, you mean in the Tk console, or when running tclsh from the command prompt? If the former, then you can just use tkcon on Unix to get the same behaviour (plus a lot more). When running at the command prompt, you could use the history command. It's not as convenient, but it works. I don't think there is any code for readline style editing for tclsh on any platform, so if it works on Windows I assume it's the windows console which makes it work (somehow).
