* lualoader: add be-list and be-switch commandsKyle Evans2026-06-044-7/+83
| | | | | | | | | | | This is useful for driving BE changes from the loader command prompt, rather than having to use the menu. Note that the active carousel in the boot environment carousel doesn't currently reflect a switch in boot environments done this way- I'm considering this only a minor bug, as you probably can't or won't go back to the menu if you're using these commands.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows something like the following local.lua to install a filter to implement its own notion of hidden BEs using a naming convention of a leading dot to hide them: -- file: /boot/lua/local.lua local core = require("core") local function be_hide(be) if core.isSingleUserBoot() then -- All BEs are accepted for single-user return true end local name = be:match("/([^/]+)$") if not name then -- Accept malformed BEs, for whatever reason return true end return name:match("^%.") == nil end if core.bootenvFilter then -- Just in case we need to be compatible with older versions of -- core.lua without the filtering functionality. core.bootenvFilter(be_hide) end -- EOF Requested by: Marek Zarychta Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D55359

* lualoader: fix pruning of non-existent default kernelKyle Evans2026-01-071-0/+6
| | | | | | | | | | | | | | | Removing the kernel from the list of available kernels is sufficient to avoid rendering it in the list, but we need more for booting to actually work. Notably, the 'kernel' loader.conf var was left intact to its default value, so if one didn't use the kernel selector in the menu then we'd try to boot the nonexistent 'kernel' instead of the new default (first autodetected). There's room to improve the error messages here, but for now let's just make it actually work correctly. PR: 292232 Fixes: d04415c520b03 ("loader: lua: remove the default kernel [...]")

Downstreams may embed their own brands in drawer.lua, and we shouldn't break them for something like this.

* stand: lua: convert orb to a new format that allows per-graphic shiftKyle Evans2025-06-133-51/+104
| | | | | | | | | | | | | | Previously, we had one shift that had to work for both the ASCII version and the image that we may draw if we have a framebuffer to play with. That makes it more difficult to get the positioning just right, so split them out into their own tables for convenience.

* lualoader: allow graphical bits to be disabled with loader_gfxKyle Evans2025-06-061-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Some people prefer the old ASCII art look and it's good to have a way to confirm that the fallbacks still work right on systems that have a functional framebuffer available. Add a loader_gfx loader.conf(5) variable to disable the eager use of graphics for these use-cases. While we're here, clean up the style in the area a little bit; the early porting that I did to lualoader did a lot of redundant ~= nil that has carried over into some of the later work. We can drop some of that, and also re-organize some of these variables to improve readability. ziaee notes that the positioning of the orb is a bit off; this is due to a change in positioning that happened in 1b4e1171315398dec ("loader: Fix orb position") to account for the image dimensions. This should be partially reverted to get it right; we shouldn't assume that we can use the same shift in gfx-* definitions for both the ASCII art and the associated image -- the {image, image_rl} pair should be converted to something more like an fbimg or gfx table that has the image, image width and a shift override to avoid messing up the ASCII positioning when disabled (or with no graphics available).

* stand: lines with comments a '"' in loader.conf are ignoredCyrus Rahman2025-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | So the problem is that the lua parser in /boot/lua/config.lua is splitting the line on the '=', sending the first match to the key and the second to the value. In the problem case, the value is: '"test b" # This is "test_directive_b"' Then the value gets matched against QVALEXPR = '"(.*)"'. This cleans up the value by removing the first and last '"', but in this case turns it into: test b" # This is "test_directive_b which then gets rejected in processEnvVar() with MSG_FAILSYN_QUOTE, since values aren't allowed to contain '"'. Changing QVALEXPR to '([-%w_]+)' fixes this problem. Since the value is explicitly prevented from containing quotes, it's not unreasonable to load it from an expression that excludes them. The only other place this is used is in the 'exec="command"' expression, which also should not contain '"' in the command value.
