Pros
Pro Standard library
Unlike *sh Tcl has a rich standard library.
Pro Sane quoting rules
Unlike in sh you don't need to quote your variable substitutions ('"$1"').
Expanding of arguments occurs mostly explicit and if yet expected in-place (e. g. using eval
or subst
) it follows strict and well clear rules.
So exec test $argv
would execute test with single argument.
And appending {*} before $argv
would execute test with all arguments (list expansion).
Pro Cross-platform
With a little care you can have the same script work on Linux, *BSD, OS X and Windows.
Pro Widely available
You can expect a reasonably recent version of Tcl to either installed or available in the repositories of any popular open source *nix.
Pro Everything is a string
Tcl can operate at the same level of abstraction as the POSIX shell, which makes it easier to manipulate the output of other programs.
Pro Tk and Expect
Pro Standalone packages
Tcl enables easy deployment through self-contained binaries known as starpacks.
Pro Rich scripting capabilities on a single line
Want to run something 5 times? Here you go: set i 0; time { puts done-[incr i] } 5
If you need real conditional cycle? Not a problem: for {set ready 0; set i 1} {$i <= 100 && !$ready} {incr i} { if {[exec do-some-thing] eq "ready" } {set ready 1} }
Want to measure performance of something or repeat it max 300 times and not longer than 1 seconds? Very simple: timerate { after 20 } 1000 300
How about notifying yourself when some http-server is back online? Sure thing: while {[catch { close [socket localhost 80] }]} { after 1000 }; puts "\7\7\7ONLINE!"
And you can do it also fully asynchronously using events etc.
Pro High performance
Pro Open source
Pro Highly customizable
By utilizing lightweight component architecture and the built in graphical designer and theming options you are able to customize a good looking app on any platform.
Pro Java 8 support
Pro Works with all IDEs
Works with NetBeans, Eclipse, IntelliJ, etc.
Pro Multi-platform development environments (via build server)
You can even use Linux desktops to build native iOS apps, no need for a Mac.
Pro Vibrant & helpful community
Pro Attractive pricing
It is possible to build production grade apps even with the free version. Pricing is decent when compared to competitors like Xamarin.
