* bug#50179: [PATCH] Add support for "bright" ANSI colors to ansi-color and term-mode @ 2021-08-24 4:02 Jim Porter 2021-08-24 12:07 ` Eli Zaretskii 0 siblings, 1 reply; 20+ messages in thread From: Jim Porter @ 2021-08-24 4:02 UTC (permalink / raw) To: 50179 [-- Attachment #1: Type: text/plain, Size: 1336 bytes --] Note: My copyright assignment paperwork is out of date, but I've already sent a message to assign@ to get it updated. Thus, these patches won't be able to merge right away. However, I wanted to start the review process now so that there's plenty of time for back-and-forth before Emacs 28.1 is released. With the administrative issues out of the way... these patches provide support for "bright" ANSI colors (SGR 90-97 and 100-107 for foreground and background, respectively)[1]. Most of the complexity here is due to the new defcustoms `*-bold-is-bright'. Enabling this results in ANSI "bold" text (SGR 1) to be rendered in the bright color palette (as well as being bold). This is a pretty common option in terminal emulators; all the ones I looked at[2] support it, and it's often the default behavior. For me, the main benefit of this option is so I can easily match the color palettes between Emacs and my terminal emulator. I've split this into two patches, one for 'ansi-color' and one for 'term-mode'. Despite the similarity in functionality, the implementations are pretty different. It might be nice if they could be unified somehow, but that may be more trouble than it's worth... - Jim [1] https://en.wikipedia.org/wiki/ANSI_escape_code#SGR_(Select_Graphic_Rendition)_parameters [2] gnome-terminal, alacritty, and PuTTY [-- Attachment #2: 0001-Add-support-for-bright-ANSI-colors-in-ansi-color.patch --] [-- Type: application/octet-stream, Size: 11382 bytes --] From 7bdaf244ec1aba9cabaeb8be3cbff7c5b798f4e8 Mon Sep 17 00:00:00 2001 From: Jim Porter <jporterbugs@gmail.com> Date: Mon, 23 Aug 2021 17:51:05 -0700 Subject: [PATCH 1/2] Add support for "bright" ANSI colors in ansi-color * lisp/ansi-color.el (ansi-bright-color-names-vector): New defcustom.

I made this a defcustom because `ansi-color-faces-vector' and `ansi-color-names-vector' are defcustoms too. More practically speaking, I'd want to customize this new variable to make these colors match the Emacs theme I use. I chose colors in this patch to complement `ansi-color-names-vector', but they'd clash with my theme. > > +(defcustom term-color-bold-is-bright nil > > + "If set to non-nil, combining ANSI bold and a color produces the bright > > +version of that color." > > + :group 'term > > + :type 'boolean > > + :version "28.1") > > Do we really need 2 separate knobs for these two features? How > probable is it that the same user will want to have bright colors in > one package, but not in the other? I doubt anyone would want to control these independently. It'd be nice to have a single defcustom for this, but I wasn't sure where it should go in that case. Would it be ok to use `ansi-color-bold-is-bright' (from patch 1 in `ansi-color.el') in `term.el'? I see that `term.el` requires `comint.el', which requires `ansi-color.el', so `term.el' should see it without changing what gets loaded. (It might even be nice to use the same definitions for the colors in both `ansi-color.el' and `term.el', but that would take a bit of work to migrate users'/themes' customizations. Maybe that's something to do for Emacs 29 so I have time to figure out a good migration path.) ^ permalink raw reply [flat|nested] 20+ messages in thread

Bright-yellow is the same color whatever the theme. At > least IMO. I wonder if others think otherwise. The colors in `ansi-bright-color-names-vector' are just the color values that get used to set face attributes on bits of text. They (and the values in the other defcustoms mentioned above) get compiled into `ansi-color-map', which contains entries like `(foreground-color . "yellow2")'. Those then get applied as face attributes onto the relevant text. While you'd always want bright-yellow to be some kind of bright-looking yellow, the exact RGB value for that is just a matter of preference. In particular, a theme might need to adjust these color values so that there's appropriate contrast between ANSI-colorized text and the default foreground/background color specified by the theme. > > Would it be ok to use `ansi-color-bold-is-bright' > > (from patch 1 in `ansi-color.el') in `term.el'? > > Yes, why not? Mostly just my relative unfamiliarity with the preferred way to do things here. `ansi-color.el' and `term.el' seemed very independent of each other, and I wasn't sure if there was a particular reason for that. I'll just use `ansi-color-bold-is-bright' for both patches then. ^ permalink raw reply [flat|nested] 20+ messages in thread

Ok, my paperwork is complete. I've attached updated patches that should apply cleanly again (I had to fix the merge to account for changes to NEWS). I also rolled my fix to the term.el tests and Eli's fix to include version info in the new term faces into the second patch. There's one further enhancement that might make sense here: currently, color values are set via a vector of strings for `ansi-color', whereas they're set via faces for `term-mode'. Would it be better to use faces for `ansi-color' too? Perhaps they should even be the *same* faces; is there any reason an Emacs user (or package) would want ANSI colors to be different between `ansi-color' and `term-mode'? If so, maybe each `term-color-FOO' face should inherit from the (hypothetical) corresponding `ansi-color-FOO' face? However, maybe there's a particular reason why `ansi-color' works this way that I'm not aware of. If the current way is best, that's fine by me too. Otherwise, just let me know and I can update the patches to include `ansi-color-FOO' faces.

(We generally prefer using faces instead of colour > names these days.) Since no one chimed in opposing this change, here's a WIP patch that adds faces to ansi-color. This removes the use for `ansi-color-map', since `ansi-color-get-face-1' does all the work now. I benchmarked this a bit and the performance seems on par with the old implementation, except when we fontify *more* stuff thanks to the support for additional ANSI escapes; in that case, it takes longer, scaling linearly with the amount that gets fontified. I also took the opportunity to redefine a couple of the faces. For example, ANSI SGR 7 (negative image) was defined to use the `error' face. Given that `:inverse-video' exists, that seems pretty suboptimal. I don't quite know what to do about man.el though. It has overrides for a few of the faces used by ansi-color. I could maintain that behavior fairly easily, but maybe it makes sense to have it use the defaults from ansi-color. More generally, I wonder what we should do to accommodate users of ansi-color who want to apply non-default faces for a specific case. I guess they could redefine `ansi-color-basic-faces-vector' and friends? That's basically how man.el used to work, and it wouldn't be hard to continue supporting that if we wanted.

I wonder why man.el is overriding the colours? Since I'm not totally sure, I maintained that behavior.

(Users > may have code that references it in their .emacs files, and that > shouldn't bug out.) Ok, I've done this here, and all the other places as well. I also obsoleted the old `ansi-color-map' and friends instead of deleting them for the same reason. Hopefully all that's right; I tried to make sure that they warn the user if they use them, but that warnings don't show up when building Emacs.

(I switched back and forth between implementations there a few times, and I guess when I made the patch I was midway between changing it back.) ^ permalink raw reply [flat|nested] 20+ messages in thread

See e.g. the Modus themes, which are designed to meet WCAG's highest standards for colour contrast. Maybe there's an analogy to make with terminal emulators? Most of those (e.g. Konsole, Terminator, Xfce's) allow the user to customize the 16-color palette. Digging into the history of this 4-bit palette[1], it almost seems like no two consoles ever used the exact same colors, so these color names might not be as absolute as say, HTML color names[2].

It's OK to set a variable. I was asking why would we want to offer users the opportunity to customize these translations. > Maybe there's an analogy to make with terminal emulators? Most of those > (e.g. Konsole, Terminator, Xfce's) allow the user to customize the > 16-color palette. Once again, if someone _really_ wants that, they can set a variable allright. I'm asking why would _we_ want that. > Digging into the history of this 4-bit palette[1], it almost seems like > no two consoles ever used the exact same colors, so these color names > might not be as absolute as say, HTML color names[2]. I don't see how this justifies a desfcustom, sorry. If there's no 110% consensus, we can choose whatever similar color we want. ^ permalink raw reply [flat|nested] 20+ messages in thread
