xterm includes its own hard-coded map

[John James Jacoby]

• I am on the latest Hyper.app version

• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: macOS 14.3 Sonoma

• Hyper.app version: latest canary

• Relevant information from devtools:

DevTools failed to load source map: Could not parse content for file:///hyper/target/xterm.js.map: Unexpected end of JSON input

• The issue is reproducible in vanilla Hyper.app: Yes

Issue

DevTools attempts to load an xterm.js.map file from the target directory.

This is because xterm.js has this at the end of it:

//# sourceMappingURL=xterm.js.map

...which makes sense from xterm's perspective, but not from Hyper's.

Uncertain when exactly this started (I think it's been a while).

Two solutions:

• modify xterm.js to strip out the manual map
• always (or conditionally, I suppose) manually require xterm.js.map
