Improve resilience of live reloading to temp IDE files

[damithc]

A console message noticed during live reloading (when using Intellij). May be useful for improving live reloading.

info: Reload for file deletion: C:\repos\nus-te3201\website\programming\files-paths\text.md___jb_tmp___
error: EPERM: operation not permitted, unlink 'C:\repos\nus-te3201\website_site\programming\files-paths\text.md___jb_tmp___'

This message did not crash the build though.

At another time the build crashed when it tried to access a file {some path}/.temp/{some path}

error: EPERM: operation not permitted, open 'C:\repos\nus-te3201\website\programming.temp\toc\expressions-types-variables.md'

More errors messages shown during live reloading (these are nothing new; just see if they can be reduced).

Error: EPERM: operation not permitted, stat 'C:\repos\nus-te3201\website\programming_site\toc\files.html'
error: EPERM: operation not permitted, open 'C:\repos\nus-te3201\website\programming.temp\toc\strings.md'
EPERM: operation not permitted, unlink 'C:\repos\nus-te3201\website\programming_site\files-reading\text.md___jb_tmp___

In addition to ignoring certain file changes, another strategy we can try is to abandon the current build gracefully (instead of crashing) and retry one more time. Some of the temporary problems with files might no longer exist during the second try.

Observation: Copy-pasting a file inside Intellij usually result in a build crash.

I ignored some of the IDE files.

markbind/index.js

Line 172 in eac242e

x => x.endsWith('___jb_tmp___'), x => x.endsWith('___jb_old___'), // IDE temp files

Haven't noticed this recently. Closing.
