Fix WSL startup compatibility for fastfetch configs#1
Conversation
📝 WalkthroughWalkthroughThe changes add fastfetch availability checks to shell startup scripts and standardize fastfetch configuration file paths from absolute/Downloads locations to ~/.config/fastfetch. Logo rendering type is changed from direct kitty to automatic across all fastfetch configurations. Documentation is updated to reflect new paths and conditional checks. Changes

277-278:⚠️ Potential issue | 🟠 MajorBind without
-xdoes not invoke shell functions — the Mikasaa GUARD is non-functional.The binding at line 278 uses
bind '"\C-m": mikasaa_check_command'without the-xflag. Per bashbindsemantics, this syntax expects a readline function name (e.g.,accept-line,beginning-of-line), not a shell command. Sincemikasaa_check_commandis a shell function, not a readline built-in, bash will fail withbash: bind: mikasaa_check_command: unknown readline function nameon every shell start, and Enter will retain its defaultaccept-linebehavior — the guard never activates.To fix, use

bind -x, the function runs withREADLINE_LINEreadable/writable. However, after the function returns, readline does not automatically re-submit the buffer; the user must press Enter a second time.

In `@fastfetch/T_Cleanup.jsonc`:
- Around line 3-4: The configs use "source": "~/.config/fastfetch/mikasa.png"
with "type": "auto", which relies on tilde expansion added in fastfetch v2.41.0;
update the README prerequisites to explicitly require fastfetch v2.41.0+
(mention the exact version) and/or add a short installation check script in the
docs that runs fastfetch --version, parses the version, and aborts with a clear
message if the installed version is older than 2.41.0; ensure the note
references the affected config files (T_Cleanup.jsonc, T_Mikasaa.jsonc,
T_Startup.jsonc, W_Command1-4.jsonc, config.jsonc) and suggests using
$HOME-expanded absolute paths as a fallback if you prefer not to enforce the
version.

- Around line 3-7: The config change updating the logo source is correct — no
code changes required; keep the "type": "auto" and the updated "source":
"~/.config/fastfetch/mikasa.png" as-is and remove any commented-out alternate
paths if you want a cleaner file (refer to the "type" and "source" entries to
locate the setting).
In `@fastfetch/T_Mikasaa.jsonc`:
- Around line 3-4: The review indicates this change is fine as-is — no code
changes required; keep the "type": "auto" and "source":
"~/.config/fastfetch/mikasa.png" fields in T_Mikasaa.jsonc unchanged to remain
consistent with the PR-wide logo update and approve the change.
In `@fastfetch/T_Startup.jsonc`:
- Around line 3-4: This change updates the logo entry to use auto-detection with
the new source path; no code changes required—leave the "type": "auto" and
"source": "~/.config/fastfetch/mikasa.png" fields in T_Startup.jsonc as-is to
remain consistent with the PR-wide logo update (verify only that the file path
exists and the image is accessible at runtime).
In `@fastfetch/W_Command2.jsonc`:
- Around line 3-4: The "source" value uses a tilde
("~/.config/fastfetch/mikasa.png") which may not be expanded by the consumer;
update the configuration so the path is absolute or uses an environment-expanded
form instead of "~". Locate the "source" key (with "type": "auto") and replace
the tilde-prefixed path with either an absolute path or a runtime-expanded value
(e.g., using $HOME or a loader that expands tildes) to match the same
tilde-handling change made in T_Cleanup.jsonc.
In `@fastfetch/W_Command3.jsonc`:
- Around line 3-4: Keep the tilde-expanded path in W_Command3.jsonc consistent
with the rest of the PR by applying the same version-gate used in
fastfetch/T_Cleanup.jsonc: ensure the "source": "~/.config/fastfetch/mikasa.png"
entry is only enabled/accepted under the same version constraint
comment/mechanism as T_Cleanup.jsonc so the tilde-handling behavior remains
uniform across the files.
In `@fastfetch/W_Command4.jsonc`:
- Around line 3-4: No change required — the "type": "auto" and "source":
"~/.config/fastfetch/mikasa.png" entries in W_Command4.jsonc correctly reflect
the PR-wide logo update; simply keep these values as-is (verify the referenced
file path exists in the target environment if needed) and proceed with the
approval.

Note
Low Risk
Doc and configuration-only changes; main risk is altered fastfetch logo rendering behavior in some terminals due to switching to
type: autoand a new default image path.Overview
Improves shell startup reliability by gating the startup
fastfetchcall inbash/.bashrc,zsh/.zshrc, and the README snippets behindcommand -v fastfetch, avoiding errors on systems where it isn’t installed.Makes all fastfetch presets portable by switching logo rendering from
kitty-directtoautoand replacing a hardcoded image path with~/.config/fastfetch/mikasa.pngacrossfastfetch/*.jsonc(includingconfig.jsonc). UpdatesReadme.mdaccordingly and adds WSL-specific troubleshooting guidance and a no-image fallback ("logo": { "type": "none" }).Written by Cursor Bugbot for commit 810beba.
