The `python` Homebrew package installs unversioned links to Python 3
executables in `/usr/local/opt/python/libexec/bin`. Add this directory
to the `PATH` environment variable when it's present.
Partially address #13 by adding the `--git <repo>` option to `sandbox
create`. This enables the quick cloning of a remote repository instead
of doing the tedious dance of creating a sandbox, cloning the remote
repo, deleting the sandbox repo them moving the `.git` directory before
doing a `git reset --hard HEAD`.
Additionally, improve the error messages for all `sandbox` commands,
clean up the completions a little, and use a consistent style in the
scripts.
The [zsh-completions](https://github.com/zsh-users/zsh-completions) repo
contains completions for various commands but not all of these are
useful so the `update-completion-links.zsh` script inspects the `PATH`
to determine which of the completions should be symlinked to
`~/.local/share/zsh/site-functions` which resides on the `fpath`.
Make using the `@vim$TMUX_PANE` window flag much more robust by
unsetting it every time the zsh prompt is drawn and setting it again
using a `FocusGained` `autocmd` in vim. This removes the need for the
hacky check for zsh in the conditional defined in the `in_vim` variable.
Fixes#18 by exiting the autoenv before invoking vim for editing the
`.enter` and `.exit` scripts, then enters the autoenv after vim exits.
This reduces the number of steps required to update the current autoenv
state.
When using `git` aliases, the alias would be highlighted red by
fast-syntax-highlighting even though the alias is valid so remove it and
go back to zsh-syntax-highlighting instead.
With `setopt nonomatch` unescaped `*` can be used in command arguments
however when passing command arguments to `vimdebug` the `*` _should_
be escaped so that the debugger e.g. `gdb` will correctly invoke the
program where `setopt nonomatch` does not apply.
In addition to setting the `~build` hashed directory, also export the
`build_dir` environment variable to enable commands like this:
```
cmake . -B$build_dir
```
VIM 8.1 added the optional plugin termdebug which integrates gdb
with separate buffers for source, output, and gdb console. This adds the
`vimdebug` command which enables the termdebug plugin and executes the
`:TermdebugCommand` with the given arguments.
Tips from [zsh-vimto](https://github.com/laurenkt/zsh-vimto).
* Remove delay when changing mode
* Enable backspace when returning to viins from vicmd mode
Following on from the previous commit, use of `RPS1` results in the
prompt being redrawn when the terminal gets narrower, this makes the
line drawn by `fresh_line_one` scroll off the screen. By removing any
use of `RPS1` this behaviour goes away.
* When a command fails, don't print the error code at the end of the
first line but directly after the git stats.
* Remove `cr` from `prompt_opts` since there is no longer a new line in
`PS1`, combined with above, this result in no new lines being inserted
when the terminal becomes narrower e.g. a horizontal tmux split.
* Remove `fresh_visible_length` function and instead use the length of
string variables e.g. `${#userhost}`.
After fixing the macOS `/etc/zprofile` issue rewriting the `PATH`
environment variable it is no longer necessary to explicitly add
`/usr/local/opt/python/libexec/bin` to `PATH` since Homebrew installed
python 2.x is installed in `/usr/local/bin` and is used by default.
