bring up to date with sorin-ionescu/prezto (#1)
Browse files Browse the repository at this point in the history
* Adds additional support for PS prompt context expansion

* Allow setting ZPREZTODIR to make prezto easier to integrate with

* Set ZPREZTODIR to ${0:h}

* Update pure prompt to v1.5.2
This fixes a security issue with malicious branch names

* update brewu method

Homebrew decided to not change the behaviour of `brew upgrade` so
`brew upgrade --all` is equivalent to `brew upgrade` without any other
arguments (so the `--all` is a no-op and can be removed).

* Use python3 for http-serve alias if available (sorin-ionescu#1193)

* Ensure code blocks are formatted properly for GitHub (sorin-ionescu#1271)

* Add support for skipping VIRTUALENVWRAPPER init in modules/python (sorin-ionescu#598)

* Support skip-virtualenvwrapper-init zstyle in python module to avoid auto-sourcing of virtualenvwrapper.sh
* Don't overwrite the WORKON_HOME env var if the user has already set it

* Don't load pfunctions from vi swap files

* Change $TMPDIR for non-interactive shells

This commit changes the way $TMPDIR is set by using `mktemp` rather
than a fixed string.

* Add "sa" alias to make it easy to search aliases

* Avoid unsetting nonexistent variables (sorin-ionescu#1075)

* Add nodenv support to Node.js module

- Implementation from sorin-ionescu#1001
- Documentation from sorin-ionescu#1178

* Prefer $(COMMAND) syntax over backticks (sorin-ionescu#1012)

* Remove extra use of grep in git-hub-shorten-url (sorin-ionescu#904)

* Add notice about potential shadowing of the gb command (sorin-ionescu#1124)

* Use less destructive git push --force-with-lease.

* Improve and simplify titling functions.

Multiplexer titles can be set independent of window and tab titles.
Add auto-title always option to have dynamic titling inside terminal
multiplexers. Setting auto-title to yes continues to ignore dynamic
titling inside terminal multiplexers.

This patch should not alter behavior under Apple terminals.

* Update zsh-autosuggestions submodule location

Thanks to @naibaf0. Closes sorin-ionescu#1096.

* Update zsh-users submodules to latest stable versions

* Update external prompt modules

* Added option to skip git aliases definition

Fixes sorin-ionescu#947

* Added support for python venv display in paradox prompt

* utility module: fix/improve colordiff call in diff

The new call is compatible with colordiff v1.0.8 - v.1.0.15 (might be
compatible with even earlier versions, but not tested), while the
original one breaks down under v1.0.14 and v1.0.15. See
daveewart/colordiff#22.

* Bump license years and tidy up readme (sorin-ionescu#1273)

* Add support for iTerm2 v3 in tab function

* Use patterns from ruby module for initializing nodenv

* Fix path in node module

* FIXED: syntax error in osx module tab function

* Only try to run python-info if it exists for the paradox prompt

* Move common promptpwd code to external function

* Ensure extendedglob is set in promptpwd

* Remove manb from completion filename

* Update fasd README with basic installation information

* Feat (aliases): add aliases for git flow

* Allow syntax highlighting pattern styles (sorin-ionescu#1192)

* completion: Cap max-errors at 7 to avoid hanging (sorin-ionescu#953)

7 is pretty arbitrarily chosen, but seems like a reasonable tradeoff, at
least the completion no longer shows symptoms of exponential
time-growth when trying to complete something completely wrong.

This fixes sorin-ionescu#946.

* Add note about working around preexisting runcoms

Closes sorin-ionescu#955

* Don't use a deprecated argument as a python example

Thanks to @jeffwidman for pointing this out

Closes sorin-ionescu#1141

* Add bundle clean alias

* Doc (ruby): add doc on bundle clean alias

* Feat (docker): add docker aliases (sorin-ionescu#1147)

Thanks to @malikoth and @saoula for their input.

* Fix indentation in README

* Update is-callable to also check builtins

Fixes sorin-ionescu#1037

* Add code style to CONTRIBUTING.md

Closes sorin-ionescu#1296

* Add note to CONTRIBUTING.md about zstyle

* Add initial issue and pull request templates

* Remove additional newlines in issue and pull request templates

* Rework diff function

This removes --unified from the default options to make it possible to pass -y
without worrying about conflicting output formats.

diffu has also been added as an alias to make it easier to get output as a
unified diff.

Fixes sorin-ionescu#1231

* Add missing alias to utility README

* Move python-info call in paradox from preexec to precmd

* archive: add support for *.jar files (sorin-ionescu#1302)

* archive: add archive function

* Add perl-info function & plenv subcommand aliases (sorin-ionescu#1303)

* Add perl-info function
* Add alias for plenv subcommands
* Load perlbrew if needed
* Load plenv if needed
* Use PERLBREW_ROOT as priority to detect Perlbrew

* Add utility alias for pydf

* New `alias gfa=git fetch --all` for git module

Also includes an updated README.md !

* Update ssh module for multi session hosts

create ssh_agent_env with current user id in file name to avoid collisions with other users
create ssh_agent_sock with current user id in file name to avoid collisions with other users

* Add support for 'pip', 'pip2', 'pip3' completion

Since `pip completion --zsh` might be slow, we cache it beforehand.
The implementation is along the lines of 'npm' completion in 'node' module.

* rsync: Update reference to Bombich's rsync page

Seems like Bombich's rsync page moved with the previous link doing 404.
Adjusted to fix this.

* Add zstyle option to show pwd in long format

* Convert long-pwd to pwd-length

* Add better support for pyenv virtualenvs

* Add some new git aliases, modify a few more. (sorin-ionescu#1301)

* Add some new git aliases, modify a few more.
* Add `gbV` command to show more verbose git branch info.
* Add `gcam` to make it possible to execute `gca; gcm '<your message
  here>'` more simply.
* Add `gii` command to temporarily untrack (ignore) a file.
* Add `giI` command to uningore a file.
* Change alias of `gbl` to `gbv`. Personally, I think aliases that
  include a switch in the command should include the switch in the alias
  if possible.  This makes them easier to remember.
* Change alias of `gbL` to `gba`. I think the `-a` switch is more
  salient to what this alias does than the `-v`.  Furthermore, with this
  PR there are already `gbv` and `gbV` aliases, so those are out.
* Change implementation of `gCl` alias to use built-in capabilities of
  git, rather than sed.
* Rename gbx and gbX to gbd and gbD respectively
* Mostly revert alias changes
* Add gbr and gbR aliases to gbm and gbM commands

* Add gbr and gbR aliases to module readme

* Use the lazy-loaded version of virtualenvwrapper if available

This shouldn't cause problems for anyone and should improve startup times for
anyone using python with virtualenvwrapper because it will wait for the first
command to load rather than right away.

* broken $path and $PATH  if nodenv exists (sorin-ionescu#1315)

This change fixes a bug where no command can be found
(e.g. `ls`) due to the $path array being set to two elements,
one of them with all the previous paths separated by spaces.
This makes zsh break $PATH, instead of colons there are
spaces, and nothing works.

The idea is to have the array be set leveraging the word splitting
that we usually are told to avoid by quoting.

* Cache the completion for a quicker startup

The original idea was by @samjonester in sorin-ionescu#1210. This version aims to avoid
relying on the stat or date programs because they have different flags depending
on the OS and if it uses BSD or GNU coreutils.

* Add the ability to specify tmux session name

* Change the zstyle config name for sorin-ionescu#607

* Allow ssh module to run on OSX

* Python virtualenv auto workon cwd hook (sorin-ionescu#1300)

* Command to activate virtualenvs on changing directory

Enables automatic activation of a virtualenv when jumping into a directory
This is done by looking in the current directory for a file or directory
named `.venv`. If it's not found in the current directory its parents will
also be examined. `.venv` can be either:
    1. A file containing the name of a virtualenv found in $WORKON_HOME
    2. A directory containing bin/activate (meaning that the directory is
       assumed to be a virtualenv.)
If $WORKON_HOME is set it is assumed that virtualenvwrapper is installed
and the `workon` command will be issued.

* Update python docs to include info on virtualenv auto-switching

* replace the deprecated abs call in the pacu alias.

* zprofile: Use non-random static TMPDIR

Closes sorin-ionescu#1319

* sorin theme: Use a proper temp file for async data

* Default sorin theme to /tmp when TMPDIR is not set

Fixes sorin-ionescu#1331

* Add git aliases for signing commits (sorin-ionescu#1126)

* Change print to printf in init.zsh error (sorin-ionescu#1335)

When my zsh had issues, and I was debugging it, this line would
end up being run but no output would be made to the screen.

Changing it from print to printf caused the error to properly be
displayed.

* fixed vivisual key binding (sorin-ionescu#1148)

Fixes sorin-ionescu#1236

* Move virtualenv auto-switch cwd hook optional loader out from inside unrelated if statement (sorin-ionescu#1338)

* Fix sorin-ionescu#1337 by removing top alias to htop. (sorin-ionescu#1341)

Fixes sorin-ionescu#1337

* [editor] Set Delete key in vicmd mode to delete character

Delete key deletes character in vimcmd cmd mode instead of weird
default functionality. The default functionality in vicmd mode
is the Delete key will change the case of many of the characters
on the screen, which is not the default thing that vim does.

This could be confusing and frustrating to users, so set it to delete
a character instead.

* Remove redundant style rules from CONTRIBUTING.md

* [runcoms/zprofile+zshenv] Ensure TMPDIR is always set

In some cases TMPDIR may not be set, in which case it could cause issues
for zsh modules.

This change was prompted by issue sorin-ionescu#1331.

Also when creating a missing TMPDIR, use mkdir --mode=700 instead
of creating the directory and then chmoding it afterward.

* [CONTRUBITING] Add section on using a secondary devel directory

Add a section on how to use a separate directory than your normal
ZDOTDIR for development with its own zprezto.

* [zprezto-update] Add convenience function to update zprezto (sorin-ionescu#1344)

* [zprezto-update] Add convenience function to update zprezto

This function checks if there is any update to zprezto, and if so
will pull in the changes. It will not attempt a pull unless
it is fastforwardable. It also makes sure the user is on the master
branch before attempting.

* [zprezto-update] Improve resilience of the function

Better error checking of status of the git repository
and better error producing.

Fit columns into mostly 80 width and add a missing printf
argument.

Use ( ) around the function so changing directory does not affect
the outer scope.

* [README] Add instructions on using zprezto-update function

* Fixed ssh-add not using SSH_ASKPASS

* [editor] set forward/backward word for Ctrl+Right Ctrl+Left

Set forward/backward word to be mapped the same as they are in vim,
instead of having weird functionality when unset.

* [utility] scp/rsync glob local paths but don't glob remote paths

Adds a function which wraps rsync and scp so that remote paths are not globbed
but local paths are globbed. This is because the programs have their own
globbing for remote paths. The wrap function globs args starting in / and ./
and doesn't glob paths with : in it as these are interpreted as remote paths
by these programs unless the path starts with / or ./

Fixes issue sorin-ionescu#1125

* Fix README example on tmux's default session name

* Updater: fix bug regarding source init in new updater logic

* [prompt/sorin] Fix branch code exploit vulnerability

Escape all $ except the first $. Escape all backtick `'s. This prevents
variable names or shell expansions placed as branch names from
remotely exploiting code.

Fixes issue sorin-ionescu#1267 for sorin prompt.

* [editor] Add bindkey-all function to show all bound keys (sorin-ionescu#1358)

* [editor] Add bindkey-all function to show all bound keys

Function which allows you to see all the bound keys for all of
the different keymaps. It does accept arguments and passes them
through to bindkey -m "$keymap" so you could set a shortcut to
all keymaps as well if you wished.

Makes it much easier to see and grep what keys are bound to each of
the different keymaps.

When no arguments are given it will print keymap headers to stderr,
if given arguments it will not print anything extra to the screen.

* [editor] Update README to include information about bindkey-all funct.

* Ensure we use the same function definition syntax everywhere

* Add comments into each of the function files to make them easier to find

* [git] Fix 'git-hub-shorten-url' helper

Changes:
- Use git.io over 'https'
- Add extra check to conform to *.github.com URLs
- Use built-in _urls function for completion
- Update readme with GitHub blog URL

* gpg: fix enable-ssh-support detection

That line may be commented in the config file.

* [editor] Fix undefined results with unbound keys in viins/vicmd

Bind the remaining unbound keys in the main mode so that they
don't result in undefined functionality when pressed. (Often this
will change the casing of one/most/all of the characters you've
typed or even stranger things). In emacs mode this usually just
inserts a tilde, but this will fix that as well so nothing happens
when unbound keys are pressed.

Since there isn't any binding which does "nothing", create a noop
ZLE widget and bind them to that.

The user or other modules are still able to override these bindings
either by overriding the main keymap or setting a keymap in one
of the other modes which will take precedence over the main fallback.

* Prefer evaluation over test for arithmetic expression

Usage of `(( ... ))` over `[[ ... ]]` is preferred for arithmetic expression
since the former is less error prone.

Also, unset local variable whenever possible.

* python: add ubuntu locations for virtualenvwrapper.sh

* [editor] Ensure unbound_keys is defined as an array

Somewhere around zsh 5.1, there was a change which turned typeset (and
most likely local) into a keyword. In older versions of zsh, using
`local x=()` will cause the () to be treated as a glob qualifier.

Fixes sorin-ionescu#1373

* [completion] Minor cleanup of zstyle completion 'tag-order'

De-duplicate common zstyle 'tag-order' for ssh, scp and rsync.

* [utility] Add safe-ops zstyle option to disable safe rm/cp/ln/mv

Currently rm/cp/ln/mv are aliased to rm/cp/ln/mv -i so that it will
prompt before removing files.

Some people would not like this functionality and wish for an easy way to
disable it. This adds a new option:

zstyle ':prezto:module:utility' safe-ops yes/no

It is enabled by default even if zstyle is not set, but can be set to no
to disable these aliases.

This should resolve issue sorin-ionescu#205

* [utility] Move the safeops aliases into their own section and add XXi variants

* Update documentation on safeops

* Add a .editorconfig file to setup tabstyle preferences

With editors that support it it will setup preferences so that it
will use 2 spaces as the indent, except in .gitignore and .gitmodules
which in our files use tabs.

For more info see http://EditorConfig.org

* Small editorconfig file cleanup

* add alias for cloning a repo including all submodules

* change alias to gfcr

* Detach from tmux if attached, before attach (sorin-ionescu#1088)

If you are in a tmux session, and auto-start is enabled
Then you `sudo su` and then `su <username>` it will re-attach, in a loop.
This resolves that problem, by forcing a detach before a (re)attach.

* git: Add revert to special action contexts

revert is very similar to cherry-pick and has a sequence variant.

* Add fasd as an external module

* fasd: fall back to submodule only if command is missing

* [command-not-found] Load brew 'command-not-found' if homebrew tap is available

Homebrew has _official_ tap that supports `command-not-found`.
Enable it when possible.

* Cleanup spurious whitespace

* utility: fix completion for rsync and scp

* [utility] Remove premature call to `compdef`

This is a temporary fix to work-around a minor regression in 90071d3.

* [utility] Update documentation for 'safe-ops'

Update formatting and wordings to be more consistent with rest of prezto
documentation.

* module(homebrew): add outdated options for cask and brew commands

* [homebrew] Add documentation for brewo and casko

* [utility] Reuse interactive aliases when 'safe-ops' is set

When `safe-ops` is set, we can reuse the aliases that are already available.

* [python] Detect actual `pip` command available for generating completion cache

We cannot always assume availability of `pip`, it can be `pip2` or `pip3`
instead. We detect the first available one and use it for generating the
completion cache.

* [general] Switch code block formatting to use fence formatting

Changes:
* Indented code block doesn't support syntax highlighting, use fenced
formatting (```) instead for better syntax highlighting
* Wrap commands/functions in backticks
* Typo fixes

* [prompt] Rename helper function `promptpwd` to `prompt-pwd` for consistency

Changes:
* In prezto, function names are hyphenated ('-') by convention,
  rename `promptpwd` to `prompt-pwd` accordingly.
* Unset local variable `current_pwd` proactively.
* Tweak additional documentation for `prompt-pwd`.

* [utility] Refactor rsync_scp wrapper function and add completion support

Changes:
- Rename `rsync_scp_wrap` to `noremoteglob` and make it more generally usable
- Enable completion support for commands wrapped with `noremoteglob`
- Tighten up internal variable usages
- Update documentation for 'noremoteglob' function

* [general] Fix incorrect fenced code indentation

* Update submodules URLs to use git URLs explicitly

Even though GitHub redirects git calls based on user-agent, using git URLs
consistently is preferable.

* [node] Always quote files when `source`-ing

* [osx] Support custom keyword used by `mand` to open man pages in Dash.app

`zstyle` based customization is now avaialble in *zpreztorc*.

* Fix unbound keys in vicmd/viins mode

Previously I made a change to try and bind these unbound keys to the main
keymap in thoughts that in vicmd or viins mode it would fallback if it wasn't
bound in vicmd/viins mode. This turned out not to be the case.

Explicitly bind the keys in both viins and vicmd mode as works properly.

* Migrate sorin prompt to zsh-async (sorin-ionescu#1385)

This includes some improvements by @indrajitr in addition to the main migration.

The first step was to avoid PROMPT and RPROMPT modification when possible (which may help resolve some other issues as well relating to zsh crashes with the sorin prompt) then update the displayed git information in a separate variable rather than a command.

We use zsh-async for creating and running background tasks. The sorin prompt uses it to update git info without blocking the prompt from displaying (because of how long it can take). In the future it may be worth moving more tasks and more prompts to using this.

The move to zsh-async does make the git prompt slower in some circumstances (most noticeable in large repos), but this is a worthwhile tradeoff to avoid the cache file which had a number of potential security holes.

We have also switched to adding zsh-async as an external submodule (rather than the version bundled with pure) which may cause some migration headaches, but it will be worth it in the long run.

* ssh: update README to reflect macOS changes

* Fix typos

* Update agnoster prompt to include security fix

Fixes sorin-ionescu#1267

* [python] Improve and document `virtualenvwrapper` initialization flow

Changes:
* Simplify zstyle name `skip-virtualenvwrapper-init` to `initialize`
  avoiding double negation in name
* Always perform `eval (pyenv virtualenv-init -)` at initialization
* Prefer `virtualenvwrapper_lazy` over `virtualenvwrapper` when available
* Honor `VIRTUALENVWRAPPER_VIRTUALENV` if it is defined.
* Document about `VIRTUALENVWRAPPER_PYTHON` and `VIRTUALENVWRAPPER_VIRTUALENV`
  (this would be particularly important in macOS after recent homebrew update)
* Add additional documentation for `initialize` in _README.md_ and _zpreztorc_
* Add aliases `py2`, `py3` as shortcut for `python2`, `python3` respectively

* [completion] Support ignoring '/etc/hosts' entries in host completion

Entries from static '/etc/hosts' can now be ignored via 'zstyle' based
configuration. Both IP address and corresponding hostname will be ignored
during host completion. However, some of the entries ignored from '/etc/hosts'
still might appear during completion because of their presence in 'ssh'
configuration ('~/.ssh/config') or history ('~/.ssh/ssh_hosts',
'~/.ssh/known_hosts' etc.).

* [completion] Allow ignores for '/etc/hosts' entries to be dynamic

By keeping the variable `_etc_host_ignores` around, it can be resolved
lazily which is turn should allow selective ignores on a per invocation
basis.

Also, `'\#'` doesn't need to be added to `_etc_host_ignores` anymore.
It is enforced inline.

* Adjust GitHub templates with commented lines

* Avoid setting TMPDIR and make sure all modules handle that properly

Fixes sorin-ionescu#1206

* ssh: check ssh-askpass presence under Linux

Check the presence of `ssh-askpass`, if `/usr/lib/ssh/x11-ssh-askpass`
is present I use it otherwise I require the passphrase in the standard
method

* [general] Miscellaneous cleanup and formatting

* [python] Detect availability of virtualenv plugins as well as pyenv

Just having 'pyenv' available doesn't imply availability of virtualenv pyenv
plugins. Check for availability of virtualenv plugins as well before attempting
to use pyenv wrapper for virtualenv.

* [prompt] Remove spurious duplicate section

Remove duplication 'Prompt Display Length' section.
Also, adjust wrapping for `~`.

* prompt: add sp option to prompt_setup functions

This was a change in zsh 5.4.1 where prompt_sp is now reset on calls to
prompt, unlike previous behavior where it was set by default. This
restores the previous default behavior.

Refs sorin-ionescu#1423, but is not a complete fix because we need to wait for
external prompts to update as well.

* prompt: remove prompt_sp from prompt_smiley_setup as it is not needed

* Revert "prompt: remove prompt_sp from prompt_smiley_setup as it is not needed"

This reverts commit 24e5e49.

* prompt: remove unneeded prompt_opts from smiley prompt

* Fix typo

* Fix typo

* Edit pyenv virtualenv-init check to support non-brew installations

If the pyenv virtualenv plugin is installed using the [pyenv-installer][1]
app script or directly via a [Git clone][2], then the pyenv-virtualenv-init
executable, that the `pyenv virtualenv-init` command uses, will not
exist in the user's PATH and therefore cannot be found using
`$commands[pyenv-virtualenv-init]`.
Installing the pyenv-virtualenv plugin in this manner is common among Linux users.

Using the pyenv `commands` command, which lists all commands pyenv can
run, we can find if the virtualenv-init command is available to pyenv
and subsequently the virtualenv plugin, without relying on
pyenv-virtualenv-init to exist in the user's PATH.

[1]: https://github.com/pyenv/pyenv-installer
[2]: https://github.com/pyenv/pyenv-virtualenv#installing-as-a-pyenv-plugin

* Update prompt_sorin_setup

Added python support

* Update prompt_sorin_setup

Moved ` ` after the virtual env info into the `zstyle` call and out of `RPROMPT`

* Update prompt_sorin_setup

Addressing a type - and switching from a custom orange to yellow (from default color list) for prompt.

* [python] Ensure availability of virtualenvwrapper file before sourcing it

* [python] Refine pyenv based virtualenv management

Now that pyenv plugins availability is detected by directly probing
'pyenv', we need to rely on the same mechanism consistently.

Further, we perform available pyenv plugin scan with native zsh
techniques instead of relying on external commands.

* Explicitly set PYENV_ROOT

* Fix English mistakes in the autosuggestions module README.md (sorin-ionescu#1444)

* Change 'conjuncture' to 'conjunction'
* Fix ambiguous pronoun references

* Update reference to Bombich's rsync

* Fix typo

* Drop `easy_install` in docs, everyone now uses `pip` (sorin-ionescu#1436)

* [python] cleanup readme formatting

Anyone want some backticks? :-)

* Use backticks rather than italics for paths

This is more typical with what I observe elsewhere

* Document that `fasd` is now bundled with prezto

Document that `fasd` is now bundled with prezto (19990c8) and that it's a fallback to a manually installed version (04bfb51).

* Swap italics to code formatting and add hyperlink

* Add missing highlighter to readme

This was added to `.zpreztorc` in 4f19700 but forgot to add it here.

* Add powerlevel9k theme

* Pin powerlevel9k submodule to latest release (v0.6.4)

* Add zsh-help function for easily searching the zsh documentation (sorin-ionescu#1360)

* Add zsh-help function for easily searching the zsh documentation

Looks up things in the zsh documentation.
Usage: zsh-help [--all] search term(s)

Option --all will seach for the term anywhere, not just at the start of a
line. When not using --all it will search nicely for terms at the beginning
of the line, which in the zsh man pages is where terms that are explained
are located, allowing you to search the zsh man pages easily.

* Improve zsh-help to search section headings before other text

Provides a much easier way to search and access ZSH's manual. First checks for
terms at the start of the manual, then checks if it's at start of a line allowing
whitespace.

Clean up some of the code a bit and format it to have a proper header for the
zprezto project with author/email and description of the function.

* [prompt_sorin] Use ✘ and show return value for non-0 rtrns (sorin-ionescu#1460)

If you do not want it to show the return code, you can set:
`zstyle ':prezto:module:prompt' show-return-val false`

* prompt: add documentation for return value display

* Updating submodules

Updating `completition`, prompt `async` and `syntax-highlighting`. All
modules where checkout to their latest tag.

* Updates outdate Mac OS X to macOS

* Fix typo in zprezto-update function

* Bind more unbound keys in viins and vicmd to nothing

Unbound keys in viins or vicmd mode have undefined results. Bind
two more of these to nothing to avoid this.

* Add make to gnu-utility commands

* archive: fix unrar-free and add support for unar (sorin-ionescu#1383)

* archive: fix unrar check when using unrar-free

unrar-free returns the error code 1 when run without arguments, thus
failing the presence check. Replacing the current presence check with
(( $+commands[unrar] )) fixes the problem.

* archive: add unar support for lsarchive and unarchive

No `archive` support with unar.

* Fix README.md for autosuggestions and history-substring-search (sorin-ionescu#1471)

* ssh: update SSH_ASKPASS workaround to more closely match what ssh-add needs

Fixes sorin-ionescu#1478

* Clarify that brewu updates AND upgrades

As homebrew includes both an update and upgrade command, it is beneficial to clarify that this performs both, rather than just the update.

* ssh: fix loading of ssh identities when none are explicitly defined

* [tmux] Avoid run tmux when the shell is executed on emacs

This avoid weird bugs to try running zsh through C-x M-x
and bug happens because obviously tmux is not designed to be
executed inside emacs.

* Document support for macOS

This adds docs for b0c85ed which was added in sorin-ionescu#1376

* Lower requirements down to 4.3.11 again (sorin-ionescu#1491)

There was an update with the syntax-highlighting module which fixed compatibility with 4.3.11.

* prompt: Add basic troubleshooting information for fonts

This is related to sorin-ionescu#1495 and a number of other issues which have been
filed about font issues.

* Update init.zsh

It seems that my older git does not support '@' yet.

* prompt: update pure to 1.6.0

#### Code Style

This project follows the [Google Shell Style Guide][5] when possible. However,
there are a number of additional things to keep in mind.

- Local variables should be used whenever possible.
- Prefer `zstyle` over environment variables for configuration.
- Prefer (( ... )) over [[ ... ]] for arithmetic expression.
- Use the function keyword to define functions.
- The 80 character hard limit can be waved for readability.

#### Using an Alternative zprezto Directory

To work on zprezto without messing with your current configuration:

```sh
mkdir devel-zprezto
cd devel-zprezto
git clone --recursive https://github.com/sorin-ionescu/prezto.git .zprezto
ZDOTDIR=$(pwd)
echo "Your development ZDOTDIR is $ZDOTDIR"

------------

Prezto will work with any recent release of Zsh, but the minimum required
version is 4.3.17.
version is 4.3.11.

1. Launch Zsh:

zsh
```console
zsh
```

2. Clone the repository:

git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"
```console
git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"
```

3. Create a new Zsh configuration by copying the Zsh configuration files
provided:

setopt EXTENDED_GLOB
for rcfile in "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/^README.md(.N); do
ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile:t}"
done
```sh
setopt EXTENDED_GLOB
for rcfile in "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/^README.md(.N); do
ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile:t}"
done
```

Note: If you already have any of the given config files, ln will error. In
simple cases you can add `source "${ZDOTDIR:-$HOME}/.zprezto/init.zsh"` to
the bottom of your `.zshrc` to load prezto but keep your config intact. For
more complicated setups, it is recommended that you back up your original
configs and replace them with the provided prezto runcoms.

4. Set Zsh as your default shell:

chsh -s /bin/zsh
```console
chsh -s /bin/zsh
```

5. Open a new Zsh terminal window or tab.

Updating
--------

Pull the latest changes and update submodules.
Run `zprezto-update` to automatically check if there is an update to zprezto.
If there are no file conflicts, zprezto and its submodules will be
automatically updated. If there are conflicts you will instructed to go into
the `$ZPREZTODIR` directory and resolve them yourself.

To pull the latest changes and update submodules manually:

git pull && git submodule update --init --recursive
```console
cd $ZPREZTODIR
git pull
git submodule update --init --recursive
