Implementation Spec for Issue #12 — ANSI Escape Code Rendering in Log View

Objective

ANSI escape codes (color sequences like \x1b[32mtext\x1b[0m) that programs emit to stdout/stderr are stored verbatim in the SQLite log database and then passed through escapeHtml() before being inserted into the DOM. This causes the raw escape sequences to appear as garbled text in every log view instead of being rendered as colored output.

The fix is to add a client-side ANSI-to-HTML conversion step in all three log rendering sites in dashboard.js, using the ansi_up JavaScript library.

Files to Modify / Create

crates/hero_proc_ui/static/js/ansi_up.min.js — Create: vendor the ansi_up UMD library
crates/hero_proc_ui/static/js/dashboard.js — Modify: replace escapeHtml() with ansiToHtml() in 3 log rendering sites
crates/hero_proc_ui/templates/base.html — Modify: add <script> tag for ansi_up before dashboard.js

Implementation Plan

Step 1 — Vendor the `ansi_up` library

Download ansi_up UMD minified build and save as crates/hero_proc_ui/static/js/ansi_up.min.js.
Dependencies: none.

Step 2 — Add `<script>` tag to `base.html`

Add <script src="{{ base_path }}/static/js/ansi_up.min.js"></script> before the dashboard.js script tag.
Dependencies: Step 1.

Step 3 — Add `ansiToHtml` helper in `dashboard.js`

Add a shared AnsiUp instance and wrapper function near the escapeHtml utility.
Dependencies: Step 2.

Step 4 — Fix Logs tab (`loadLogs` ~line 2011)

Replace escapeHtml(l.content) with ansiToHtml(l.content) in the log line renderer.
Dependencies: Step 3.

Step 5 — Fix Job detail side panel (`viewJob` ~line 773)

Replace escapeHtml(l.line || l.content) with ansiToHtml(l.line || l.content).
Dependencies: Step 3.

Step 6 — Fix Job detail modal (`showJobModal` ~line 2050)

Replace escapeHtml(l.line || l.content) with ansiToHtml(l.line || l.content).
Dependencies: Step 3.

Acceptance Criteria

ANSI colors render in Logs tab
ANSI colors render in Job detail side panel
ANSI colors render in Job detail modal
Plain-text logs still display correctly
HTML special chars (<, >, &) still escaped correctly (XSS safe)
No JS console errors on page load
cargo build -p hero_proc_ui succeeds
Browser test via MCP: ANSI-colored script output appears colored

Notes

XSS: ansi_up HTML-escapes content internally — do NOT call escapeHtml() on log content before ansiToHtml().
Library: ansi_up v6.x UMD, ~7 KB, no CDN, embedded via rust-embed like other vendor libs.
No server-side changes needed — ANSI codes are already stored correctly.

Implementation Complete

Changes Made

New file:

crates/hero_proc_ui/static/js/ansi_up.min.js — vendored ansi_up v6 UMD library (~22 KB), embedded via rust-embed like other vendor libs (xterm.min.js, marked.min.js, etc.)

Modified files:

crates/hero_proc_ui/templates/base.html — added <script> tag for ansi_up.min.js before dashboard.js
crates/hero_proc_ui/static/js/dashboard.js:
- Added shared AnsiUp instance and ansiToHtml() helper function (after escapeHtml)
- Replaced escapeHtml(l.content) with ansiToHtml(l.content) in loadLogs (Logs tab)
- Replaced escapeHtml(l.line || l.content) with ansiToHtml(...) in viewJob (Job detail panel)
- Replaced escapeHtml(l.line || l.content) with ansiToHtml(...) in showJobModal (Job detail modal)

How It Works

ANSI escape codes (e.g. \x1b[32mGREEN\x1b[0m) are now processed by ansi_up which converts them to <span style="color:rgb(...)"> elements instead of being displayed as raw text. The ansi_up library handles HTML-escaping internally, maintaining XSS safety. Plain text logs (no ANSI codes) continue to display identically to before.

Test Results

Build: ✅ Success (cargo build -p hero_proc_ui)
Tests: ✅ 355/355 passed (370 total, 15 ignored/doc-tests requiring live DB)
