UG/NX Post Tcl Tools

A focused VS Code toolbox for Siemens NX/UG Post Builder files. It turns mixed .tcl, .def, and .pui postprocessor projects into a more readable, navigable, and previewable editing experience.

Highlights

• Rich language support for NX postprocessor Tcl, DEF, and PUI files.
• Syntax and semantic highlighting for PB_CMD_*, MOM_*, mom_*, pb_*, NC words, Tcl variables, DEF declarations, strings, comments, numbers, and operators.
• Hover previews for Post Builder FORMAT, ADDRESS, and BLOCK_TEMPLATE definitions.
• BLOCK_TEMPLATE previews resolve static Tcl values such as $mom_sys_output_code(INCREMENTAL), $mom_sys_home_pos(0), and leader references like [$mom_sys_leader(X)].
• Cross-file indexing across matching .tcl, .def, and .pui files.
• Ctrl+Click / F12 navigation for Tcl procs, DEF formats, addresses, block templates, and PUI event commands.
• Context-aware completions for Tcl procs, block templates, addresses, formats, events, variables, common snippets, the NX 2506 native MOM_* command catalog, and the full system mom_* variable catalog.
• Native MOM_* commands are distinguished from user event procedures and provide Siemens NX 2506 calling syntax and descriptions on hover.
• Hover documentation for system MOM variables, including category, data type, default, possible values, and the Siemens description.
• A UG/NX Post Events explorer view that groups PUI event sequences and opens the best available Tcl or DEF target.
• A Post Builder aware formatter that keeps braces, continuation lines, table-like PUI rows, and Tcl section dividers tidy.

Preview Examples

Hover a format definition:

FORMAT Feed "&__7.2_"

The preview explains width, decimal places, sign behavior, padding, and example output.

Hover an address:

ADDRESS X
{
    FORMAT      Coordinate
    LEADER      [$mom_sys_leader(X)]
}

The preview shows the address settings, linked format, resolved leader, and sample output such as X0.000.

Hover a block template:

BLOCK_TEMPLATE tool_change_3
{
    G_mode[$mom_sys_output_code(INCREMENTAL)]
    G[30]
    X[$mom_sys_home_pos(0)]
    Y[0]
}

The preview shows the raw template items and a compact NC-style output preview such as:

G91 G30 X0.000 Y0.000

Formatter

Use Format Document after opening a file in UG Tcl mode. The formatter uses 3-space indentation and understands Tcl/DEF/PUI nesting, escaped braces, escaped quotes, hashes inside strings, and continuation-line indentation.
