# 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 extremely inefficient in its execution, uses

only lexical variables, and does not support much of the syntax of the Tcl

l anguage.

## 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.

```sh

cd tentcl

make all

```

## TESTING

```sh

make test

```

## LIMITATIONS

* Terrible runtime.

* Terrible spaghetti-code parsing.

* No non-numerical comparisons for conditionals (`expr` uses `mathexpr`, which does not

  support non-`int` types)

* Inefficient.

* Not thoroughly tested.

* Other things.
