Writing new tests
|
||||||
|
-----------------
|
||||||
|
|
||||||
|
An experimental tool is available to generate test files:
|
||||||
|
|
||||||
|
zsh -f tests/generate.zsh 'ls -x' \
|
||||||
|
| sed s/YYYY/$(date +%Y)/ \
|
||||||
|
> highlighters/main/test-data/foo.zsh
|
||||||
|
git add -N $_
|
||||||
|
|
||||||
|
This generates a test file based on the current highlighting of the given `$BUFFER`
|
||||||
|
(in this case, `ls -x`).
|
||||||
|
|
||||||
|
_This tool is experimental._ Its interface may change. In particular it may
|
||||||
|
grow ways to set `$PREBUFFER` and/or `$ZSH_HIGHLIGHT_HIGHLIGHTERS` or to
|
||||||
|
inject free-form code into the generated file.
