(Review updated until commit

Logic Change
The installation logic for Fisher and Catppuccin has been wrapped in conditional checks. While this improves idempotency, the use of
fish -c "type -q fisher"is a change from the previouscommand -vcheck. Ensure thatfishis guaranteed to be in the PATH at this stage of the script execution.Sed Safety
The
replacefunction now usesescapeSedPatternandescapeSedReplacement. Since the implementation of these escaping functions is not visible in the diff, it is critical to verify they correctly handle the delimiter used in thesedcommand (which is|) to prevent syntax errors or injection.PR Code Suggestions ✨
Explore these optional code suggestions:
Escape the delimiter in sed patterns
The
sedcommand uses|as a delimiter, but thepatternvariable is not escaped. Ifpatterncontains a|character, thesedcommand will fail or behave unexpectedly.Ensure the pattern is also escaped or use a delimiter that is guaranteed not to
appear in the input.
installer/utils.sh [670]
Suggestion importance[1-10]: 7
__
Why: The
replacefunction inutils.shuses|as aseddelimiter. While the replacement string is now escaped in this PR, the search pattern is not. If the$patternvariable contains the|character, thesedcommand will fail.Fix potential sed delimiter collision
The
sedcommand uses/as a delimiter, butescapeSedReplacementlikely only escapescharacters for the replacement string (like
&or</code>). IfescapedSuffixcontains a/,the
sedcommand will break. Use a different delimiter like|or ensure/is alsoescaped.
installer/software/software.sh [180-181]
Suggestion importance[1-10]: 6
__
Why: The
sedcommand on line 181 uses/as a delimiter. If theescapedSuffix(which contains the hostname) contains a/, the command will break. Using a less common delimiter like|is a standard safety practice in shell scripting.Avoid piping curl directly to source
Piping a remote script directly into
sourcewithin a subshell is risky if thedownload is interrupted or the source is compromised. Additionally, if the
curlfails, the
sourcecommand might still execute with partial or no input depending onshell behavior. Consider downloading to a temporary file first and verifying it.
installer/system/system.sh [337]
Suggestion importance[1-10]: 5
__
Why: Piping
curldirectly tosourceis a common but risky pattern. While the suggestion improves robustness against partial downloads, the impact is moderate as this is an installer script where such patterns are frequently used for convenience./review
