frink

What: Frink - Source code formatter

 Where: http://catless.ncl.ac.uk/Programs/Frink/
        ftp://catless.ncl.ac.uk/pub/
 Description: Program to prettify (like the indent command) your Tcl/Tk
        program.  Frink can format, minimize and/or obfuscate your Tcl code.
        It can take some forms of your code and convert it to use message
        catalogs (used for internationalization).  It applies a variety
        of heuristics to the code to try to detect possible errors.
        Supports only vanilla tcl - not extensions such as tclX, itcl, etc.
        Does however recognize namespace and interp commands.
        Check the first URL on a regular basis for updates.
        Does not permit commercial use.
        Currently at version 2.2.2p4, with an ancient 2.3.1 alpha also available at the above ftp site.

This tool by Lindsay Marshall does Static syntax analysis.

See also "debugging" in general.

Frink makes a brief appearance in a UnixReview.com column in April 2002 [1 ].


Note: Be very careful using frink to reformat your source code. Double check the frink results against the original source. It messes up your code every once and a while.


Question: What flags do you find most useful when using frink to check for errors/warnings?

Answer:

 frink -HJ source.tcl

although I sometimes use

 frink -JF FFFFE source.tcl

to turn off a warning for the construct variable $varname PT

LV I use frink -J -U -H to give me a LOT of possible issues; by the time I've checked them all (and I have run the code through tclchecker), I am ready to move on to looking at algorithm problems...


Peter Newman 25 April 2004: The frink web site doesn't seem to have any Windows Binaries. But there's one in the ASED Tclkit/Starpack. Just download and SDX unwrap that.

EKB 16 April 2005: Another Windows binary is available at http://tclsoap.sourceforge.net/dom-packages.html . (v2.1.5)

LV What are your preferences for frink pretty printing arguments?
