Tentcl

Tentcl is a small hand-parsed Tcl interpreter. This project was undertaken
to better my understanding of the parsing and interpretation of programming
languages.

It is an old project which was started in 2006. It is by no means complete,
nor is it well-written -- it is more of a toy than something useful. It is
extremely and inefficient in its execution, uses only lexical variables, and
does not support much of the syntax of the Tcl language.

It is online for historical purposes only; although, in my opinion, the code
is rather neatly written. But I am biased.

BUILD REQUIREMENTS

In additional to the Tentcl source code, you will also need the mathexpr
source code, which must be placed in the Tentcl root directory. e.g.

  tentcl
  |- src/
  |- mathexpr/
  |- dstructs/
  |- lineread/
  |- Makefile

BUILDING

To build the tclsh program, run the following. Run ./tclsh to run a Tcl REPL, or
./tclsh --help for other execution options.

cd tentcl
make all

LIMITATIONS

  • No non-numerical comparisons for conditionals (expr uses mathexpr, which does not
    support non-int types)
  • Inefficient.
  • Not thoroughly tested.
  • Other things.
