some times misses first character

[oryband]

Some time when I start typing a command, the first characters is ignored:

$ d ~/documents/  # i actually typed `cd ~/documents/`

This has started since I started using this plugin in two different machines, ubuntu and arch.

[danielshahaf]

I presume this doesn't happen under zsh -f.

Do you any bindkey c … calls in your configuration? Do you source zsh-syntax-highlighting.zsh as the last thing in your .zshrc?

[oryband]

• what is -f? couldn't find it in the man or web (never found a good way to search for -X arguments as google interprets it as "don't show 'X'"
• now bindkeys at all
• highlighting isn't sourced last, but somewhere in the middle
  here are my .zshrc, .zshenv, and .zlogin (i use arch so i startx through zlogin). they're not long, perhaps you can find the culprit

thanks a lot! :)

It's "ignore (most) user and system dotfiles". See man zshoptions. Or make your search query "zsh -f" with quotes, in which case the first result gives the answer.

I'm not familiar with oh-my-zsh, but try making zsh-syntax-highlighting the last element of the plugins array.

[danielshahaf]

I'm guessing this is resolved.

[oryband]

@danielshahaf sorry for late reply, but i can confirm that since sourcing the plugin last in the plugin list, this problem has gone away.

EDIT: forget what i said, the plugin was turned off. I'll get to this issue soon. Can you please re-open?

might be worth to mention it in the docs though, it's not obvious for newcomers.

[danielshahaf]

Reopened. I don't understand what docs change you are proposing?

[oryband]

@danielshahaf i meant emphasizing that the zsh-syntax-highlighter should be sourced after all other zsh plugins.

for example, i'm sourcing this plugin using oh-my-zsh. so i have this in my .zshrc:

plugins=(
    archlinux systemd
    python pip django celery virtualenv virtualenvwrapper
    npm
    go
    aws tugboat
    tmux
    docker
    colored-man colorize web-search
    history-substring-search
    zsh-syntax-highlighting # syntax-highlighting plugin must be sourced last
)

[danielshahaf]

@oryband zsh-syntax-highlighting/README.md already says that (in the installation instructions, and reemphasized in the FAQ later in the file). What would you change / add?

[oryband]

@danielshahaf maybe be more direct. Write:

The plugin must be sourced last in the plugin list in `~/.zshrc`:

instead of:

Activate the plugin in ~/.zshrc (in last position):

Incidentally, the 'at end of .zshrc' requirement may be removed some day, if/when the redrawhook work is merged.

@danielshahaf looks good 👍

[oryband]

keep this issue open though, i want to debug the missing char problem and haven't got to it yet

Alright. I suspect history-substring-search might have something to do with it; it duplicates some code from zsh-syntax-highlighting.zsh: https://github.com/robbyrussell/oh-my-zsh/blob/aa15ebad3e9c86fbd8dd5f01803066f82ece9593/plugins/history-substring-search/history-substring-search.zsh#L180

[oryband]

@danielshahaf can these two plugins coexist together? history-substring-search says to source itself after zsh-syntax-highlighting. They're contradicting each other!

[danielshahaf]

The documentation of h-s-s says it is compatible with z-sy-h. However, h-s-s relies on undocumented implementation details of z-sy-h (such as the existence of a _zsh_highlight function). That suggests using both at the same time is possible (since h-s-s's docs says so) but brittle (since h-s-s relies on z-sy-h implementation details which may change without notice).

While you're here, are you in contact with h-s-s's authors? The use of return true in their code could be a bug: that statement sets $? not to zero but to integer value of the shell parameter $true.

[oryband]

@danielshahaf i'm not in touch with them, just an observer. i actually don't know anything about the implementation. maybe ping them upstream?

[danielshahaf]

It's already fixed upstream: zsh-users/zsh-history-substring-search@c61c995

What about your missing character problems, have you got to the bottom of them yet?

[oryband]

yup! thanks :)
