tclint 0.2.5

A CLI utility for linting and analyzing Tcl code.

tclint  

tclint is a lint tool for Tcl. It analyzes Tcl source files and reports stylistic and functional errors that may inhibit readability or correctness.

Features

• Configurable style checks
• Usage checks for built-in commands
• More coming soon!

Getting Started

Install tclint from PyPI using pipx (recommended):

pipx install tclint

Or with pip:

pip install tclint

Run tclint on a Tcl source file by providing its path as a positional argument:

tclint example.tcl

If the file contains any lint violations, they will be printed and tclint will return a non-zero exit code. Otherwise, the output will be empty and tclint will exit successfully.

Example

$ cat example.tcl
puts too many arguments !
  puts "unexpected indent"
puts   "too many spaces after command"
$ tclint example.tcl
example.tcl:1:1: too many args to puts: got 4, expected no more than 3 [command-args]
example.tcl:2:1: expected indent of 0 spaces, got 2 [indent]
example.tcl:3:5: expected 1 space between words, got 3 [spacing]

Usage

tclint is a command-line utility. It takes a list of paths as positional arguments, which may either be direct paths to source files, or directories which will be recursively searched for files ending in .tcl, .sdc, .xdc, or .upf.

Collected files will be checked for lint violations. See the Violations documentation page for a description of all lint violations tclint may report.

Aspects of tclint's behavior can be controlled by a configuration file. By default, tclint will look for a file named tclint.toml or .tclint in the current working directory (in that order), but a path to an alternate configuration file can be provided using the -c or --config flag. See Configuration for documentation on the configuration file.
