ltm

In-process Lua text transforms over multi-cursor selections for the micro editor. A faster successor to invoking a shell-based tool once per cursor.

Ops

One micro command ltm with 14 sub-ops dispatched on the first positional arg.

> ltm eval                       evaluate each cursor's selection as a Lua expression
> ltm seq FIRST STEP [-z | -p]   generate FIRST, FIRST+STEP, ... one per cursor
> ltm dec2hex                    convert each selection from decimal to hex
> ltm dec2oct
> ltm dec2bin
> ltm hex2dec
> ltm hex2oct
> ltm hex2bin
> ltm oct2dec
> ltm oct2hex
> ltm oct2bin
> ltm bin2dec
> ltm bin2hex
> ltm bin2oct

Behavior

• Per cursor: selection text is the input; the result replaces the selection, or is inserted at the cursor position if there was no selection. Edits are applied in buffer-position descending order so they stay valid under any cursor ordering returned by micro.
• eval uses pure Lua. The math table is flattened into the expression scope, so sqrt(2), pi, floor(3.7) work bare. Other globals (tostring, string.format, ...) remain reachable namespaced. Errors in the expression replace the selection with the error message text.
• seq always emits one value per cursor. -z zero-pads (sign aware), -p space-pads. Padding width is computed from the full generated sequence.
• The 12 base shortcuts treat the selection as a single value. Empty selections are skipped. Selections that aren't valid in the from-base are replaced with the literal string "nil". The prefixes 0x, 0o, 0b (case-insensitive) are stripped only when they match the from-base.

Install

Clone into micro's plugin directory:

git clone https://github.com/Tubbles/ltm.git ~/.config/micro/plug/ltm

Micro picks it up at next launch. See > help ltm (from micro's command prompt) for the full reference.

Tests

busted spec/

The pure modules (util, seq, convert, eval, dispatch) all have spec coverage. The micro adapter (ltm.lua) is the only file that touches micro's plugin API and is verified by manual smoke in the editor.
