provider#node#can_inspect will fail on some systems because it is common
to have old node versions in OS (any Linux OS that has LTS releases)
and CI (Travis, Appveyor).
NODE_PATH can be trivially set with VimL.
Build scripts don't have to set it for the nodejs tests to work.
NODE_PATH is optional to begin with and is used only as a workaround
for the neovim node.js host.
ci: install nodejs 8 in Appveyor, Travis
provider: check node version for debug support
Resolve https://github.com/neovim/neovim/pull/7577#issuecomment-350590592 for Unix.
provider: test if nodejs in ci supports --inspect-brk
nodejs host for neovim requires nodejs 6+ to work properly.
nodejs 6.12+ or 7.6+ is required for debug support via `node --inspect-brk`.
provider: run cli.js of nodejs host directly
npm shims are useless because the user cannot set node to debug mode via
--inspect-brk. This is problematic on Windows which use batchfiles and
shell scripts to compensate for not supporting shebang.
The patch uses `npm root -g` to get the absolute path of the global npm
modules. If that fails, then the user did not install neovim npm package
globally. Use that absolute path to find `neovim/bin/cli.js`, which is
what the npm shim actually runs with node. glob() is for a simple file
check in case bin/ is removed because the npm shims are ignored now.
closes#7429
Problem: after a help window was closed, a window was selected and its
autocommands triggered. After that, restore_snapshot was called and the
focused window changed, confusing the user.
Solution: Add function get_snapshot_focus() that returns the window that
holds the cursor in a snapshot. Use this function in win_close to make
sure the right window is selected before any autocommand is triggered.
filter('v:_null_list, 'v:val') should return v:_null_list and a similar
statement should hold for map.
Changes after review
* Test inserted in legacy test suite has been removed by reverting the commit
adding it.
* Change the fix to tv_copy the argument before returning.
* Readd the two tests on crashes, and modified their expected return value.
* Move the test from 'incorrect behaviour' section to 'correct behaviour section'
* Add analogous tests for v:_null_dict
Always copy list or dictionary to return variable
If the type of input is correct (i.e. either a list or a dictionary), this
should also be returned.
Note: there are three changes to ascii_isident. Reverting first two (in
find_special_key and first in get_special_key_code) normally fails the new test
with empty &isident, but reverting the third does not. Hence adding `>` to
&isident.
