pytcl
Pure Python TCL interpreter and parser library.
Installation
pip install pytcl
Usage
Interpreter
from pytcl.interpreter import Interpreter
i = Interpreter()
i.substitute_string("set x 42") # "42"
i.substitute_string("expr {$x * 2}") # "84"
i.substitute_string("set x") # "84"
Evaluate a .tcl file:
from pathlib import Path
from pytcl.interpreter import Interpreter
i = Interpreter()
i.substitute_file(Path("script.tcl"))
Custom commands
Commands are plain callables stored in the namespace:
from pytcl.interpreter import Interpreter
i = Interpreter()
i.namespace["double"] = lambda args, ns: str(int(args[0]) * 2)
i.substitute_string("double 21") # "42"
Parser
Parse Tcl source into a typed tree without executing it:
from pytcl.words import TCLScript
script = TCLScript.read(iter("set x [expr {1 + 2}]"))
for command in script.commands:
print(command.name, command.args)
Built-in commands
set, unset, expr, if / elseif / else, while, foreach, proc, return, break, continue, incr, append, puts, error
