`exec` removes fish from the shell "stack", so SHLVL needs to be
decremented to match. This means `exec fish` will result in the same
SHLVL in the new fish instance.
Also tweak the SHLVL logic to interpret an environment SHLVL of "3foo"
as garbage instead of as the value "3".
Fixes#1693.
The wrong lock was being taken around the result queue, leading to the
occasional crash when processing interactive input. This didn't seem to
really affect normal day-to-day usage, but it did sometimes cause the
interactive tests to crash.
Fixes#1692.
As far as I know we can't access the build artifacts from Travis, so we
can't check the interactive logs after a test failure. Add an
environment variable that causes the test runner to dump the logs
itself, and set that variable for Travis.
Split `make test` into two targets `make test_low_level` and `make
test_fishscript`, primarily so fishscript tests can be rechecked quickly
after edits.
Reformat the test.fish file and update some of the code to be a little
more straightforward (e.g. `if not cmd` instead of `if cmd; else`).
This includes:
- Fixing some typos and misspellings
- Being consistent with pronouns (she/he)
- Hyphenating "built-in" and "command-line" where appropriate
Widened 'Commands' menu + fish logo
fish logo added to FAQ menu
'Commands' menu content aligned with Docs menu
'FAQ' menu content aligned and made 1st order as all entires are long
and wrap.
Setting a non-existant path component to PATH logs an error to stderr.
This is not appropriate for non-interactive temporary modifications,
like the one done by the `sudo` completion helper function.
Major documentation cleanup and update.
- Fixes Issue #1557
- Moves entire documentation to Markdown format. Much simpler.
- Fully supports Doxygen 1.8.7+
- All documentation targets updated: user_doc, share/man, doc and
doc/refman.pdf.
- Tested across Ubuntu, CentOS and Mac OS.
See doc_src/FORMATTING.md for in depth rationale and style guide.
Doxygen 1.8.6 and lower do not have the \\htmlonly[block] directive
which fixes a multitude of problems in the rendering of the docs. In
Doxygen 1.8.7 the list of understood HTML entities was greatly
increased. I tested earlier versions and many little issues returned.
