Better error message

[leesei]

It helps the user identify and fix errors if we

• throw sensible errors
• print warnings more verbosely.

Do comment if you found some area that needs improving.

EDIT I have a WIP branch here:
https://github.com/leesei/hexo/commits/better-error-message

To use this branch:

npm i leesei/hexo#better-error-message

[leesei]

slug not found

Hexo fails silently upon this:
#1562
#1594

Test all tag plugins and check how they handle space
hexo cannot use space within tag plugin arguments | Life & Note - winterTTr
Add test cases

[leesei]

_config.yaml

YAML is quite strict in its format and Hexo does not report YAML parsing error properly.
We should catch parsing error early, log and abort the operation.

hexojs/hexo-deployer-git#15
#1263
#11

add resource like:

• YAMLlint - The YAML Validator
• Online YAML Parser
• Validate your .travis.yml file

Missing theme

Better trace of invalid tag

The erroneous tag/syntax causing Nunjunk/Swig error are not easy to read. The line and column refer to intermediate HTML generated from MD.

Thank you for looking into these.

The error message that hexo s or g print is very bad. It doesn't mention which file, row and columns that cause generating failure. So every time I have to spend long time finding what error is

[leesei]

Stack trace color

Currently the stack track is logged in grey, which is hard to read

Done, see hexojs/hexo-log#1

[nickdesaulniers]

did this ever get merged? Seeing an unknown tag error, and while I can grep for the tag, a readable error message rather than a stack trace that listed the source file would be 💯

[leesei]

ping @tommy351, please merge the PR for hexo-log first.

[NoahDragon]

Both changes are merged, thank you.
