Can't render italics

[anrddh]

• I am on the latest Hyper.app version

• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: macOS Sierra 10.12.2

• Hyper.app version: 1.1.0

• Link of a Gist with the contents of your .hyper.js: https://gist.github.com/awesomeaniruddh/7129bf3d86b515e139ec5b68ec4c57df

• The issue is reproducible in vanilla Hyper.app: Yep

Issue

^ The same file in iTerm2:

The italics aren't rendering: HyperTerm renders the comments with a ugly grey background.

I too would like to see this addressed.

Is this still an issue in 2.0?

[audunolsen]

It is. Currently using the font Menlo which has an italic set.

You can determine if a terminal supports italics by running this command:

echo -e "\e[3m foo \e[23m"

Hyper does not render italics, while Apple's terminal do.

Seems like xterm doesn't support italics, this is a screenshot from your test command in VS Code (that also uses xterm for rendering)

[albinekb]

Upstream issue: xtermjs/xterm.js#580

[flybayer]

I just opened a pull request to xterm that adds support for italic! xtermjs/xterm.js#1422

[flybayer]

xterm PR adding italic support has been merged! >> xtermjs/xterm.js#1422

[lyndsysimon]

Any idea when we'll see this in the release version of Hyper?

[lokesh-krishna]

Any update regarding this?

[lyndsysimon]

@lokesh-krishna Well, it seems like the underlying issue was with xtermjs, not Hyper, and that the issue has a fix in place. The canary branch shows to be using a version of xtermjs with the fix included, but the lastest full release was 2.0.0, which doesn't include it.

If you want this to be applied through your OS's package manager, you'll have to wait for the 2.1.0 release to go live and your OS's repositories to update their version. Otherwise, you can download 2.1.0-canary.2 and it works today :)

ETA: Actually, you can modify your hyper.js to change your update channel to canary, and Hyper will update itself. If you download the canary version manually and don't change your hyper.js, it'll immediately download 2.0.0 again and prompt you to restart.

module.exports = {
  config: {
    updateChannel: 'canary',

[lokesh-krishna]

I just installed the 2.1.0-canary.2 release and tested italics support by entering echo -e "\e[3m foo \e[23m". The output was the same as earlier and not in italics. Does this require any additional configuration?

[oguzbilgic]

@lokesh-krishna were you able to solve the issue? I'm on v2.1 stable but italics are still not working

[lokesh-krishna]

I'm on 2.1.0-canary.3 now and even this version doesn't support italics.
So no, haven't been able to solve this.

[audunolsen]

This may be slightly off topic, but hyper now successfully displays italics (canary) for me — except in vim/neovim. I wonder if anyone is familiar with this? @anrddh You reported this with screenshots explicitly showing Neovim, has this resolved for you?

[jasonoverby]

@audunolsen I am experiencing the same issue where italics are present except for vim/neovim

[ntwb]

I just came looking to see if Hyper supported italics, it appears v2.1.2 is working for me:

Above with the Input Mono font, below with Operator Mono font

[audunolsen]

This may be slightly of topic for this issue, but I was able to resolve my own spesific problem; Vim and pretty much everything but Neovim was able to display italics. I wanted italics specifically for Neovim. I ran the following script which I was fortunate enough to stumble across. The script fixes the terminals' escape sequences for italics. This should probably be addressed by xterm, so this workaround can be avoided.

Hyper 3.0.2 (stable) here, italics don't work, neither from echo -e "\e[3m foo \e[23m", or in vim.

I've tested with fonts Menlo and Ubuntu Mono, which do have an italic typeface.

[Stanzilla]

Can you try with a CI build of current canary or maybe compile one yourself?

[thenerdlawyer]

i am having this issue with 3.02 stable and canary. Tried numerous fonts with italic typefaces including Input Mono, Menlo, and MesloLGS NF.

Running ubuntu on WLS

I'm having this issue with 3.02 (stable) for both WebGL and Canvas renderer, and 3.1.0-canary.1 for Canvas renderer. I'm using Victor Mono font. I'd run echo -e "\e[3mitalic\e[23m" on WSL Ubuntu on Windows 10 (1909).

Same here! did you find a fix?

This solves my problem! Italics are now rendering with vim-gruvbox. Thank you!
