Select region in Emacs

Open one or more files in Emacs and select (activate the region around) the code or text most relevant to the current discussion using emacsclient --eval. This allows the user to immediately act on the selection: narrow, copy, refactor, comment, etc.

Determine the relevant files and line ranges from the most recent interaction context.

How to select

First, locate agent-skill-select.el which lives alongside this skill file at skills/select/agent-skill-select.el in the emacs-skills plugin directory.

emacsclient --eval ' (progn (load "/path/to/skills/select/agent-skill-select.el" nil t) (agent-skill-select :selections (quote (("/path/to/file1.el" :start 10 :end 25) ("/path/to/file2.el" :start 5 :end 12)))))'

:start is the 1-indexed start line.

:end is the 1-indexed end line.

The last file visited will have the visually active region. Other files have mark and point set (use C-x C-x to reactivate when switching to them).

Rules

Use absolute paths for files.

Choose the region most relevant to the current discussion (e.g., a function just modified, a block with an error, code just generated).

If no specific region is apparent, select the entire relevant function or block.

Locate agent-skill-select.el relative to this skill file's directory.

If no relevant files or regions exist in the recent interaction, inform the user.

Run the emacsclient --eval command via the Bash tool.
