<h1 data-number="12" id="8-fisher-plugins">8. FISHER PLUGINS</h1>
<p>Fisher is bootstrapped automatically on the <strong>first interactive
session</strong> via <code>conf.d/first_run.fish</code>. This also
applies the Catppuccin Mocha theme and prints a one-time welcome message
(gated by __fish_config_op_greeting; set it to 0 to suppress).
Subsequent sessions skip all first-run logic with zero overhead.</p>
<p>To re-trigger first-run initialization (e.g., after a fresh install
or for testing), run:</p>
<pre><code>set -Ue __fish_config_first_run_complete</code></pre>
<p>Then open a new shell.</p>
<h2 data-number="12.1" id="fisher-managed-plugins">Fisher-Managed
Plugins</h2>
<p>The following plugins are fully managed by Fisher. Their files are
installed into the repo directory by Fisher and are listed in
<code>.gitignore</code> — do not commit them. Fisher installs and
updates them automatically.</p>
<pre><code>jorgebucaran/fisher Plugin manager itself
meaningful-ooo/sponge Remove failed commands from history</code></pre>
<h2 data-number="12.2" id="sponge-history-filtering">Sponge History
Filtering</h2>
<p>Sponge removes failed commands from history and, via
conf.d/sponge_privacy.fish, also filters privacy-sensitive commands
through three layers:</p>
<p>Layer 1 — Static patterns (universal, persistent across sessions):
Commands matching any of these structural signatures are never
recorded:</p>
<pre><code>--password / --token / --passphrase / --api-key flags with values
Inline env assignments: GITHUB_TOKEN=xxx, MY_API_KEY=abc
Fish set with sensitive names: set -gx GITHUB_TOKEN xxx
URLs with embedded credentials: https://user:pass@host
HTTP Authorization headers: curl -H &quot;Authorization: ...&quot;
Basic auth flags: curl -u user:pass
sshpass, docker login -p, openssl -passin/-passout</code></pre>
<p>Layer 2 — Dynamic secret values (session globals, refreshed each
login): On the first prompt, after secrets.fish has loaded, the literal
values of all exported variables whose names suggest credentials (TOKEN,
PASSWORD, SECRET, API_KEY, etc.) are collected, regex-escaped, and added
as a session-scoped overlay. Because globals shadow universals in Fish,
the combined list is what sponge sees. Rotating a token takes effect on
the next login automatically.</p>
<p>Layer 3 — Per-command filter (sponge_filter_secrets): Catches
credentials in variables exported after login, such as tokens sourced
from a project .env file mid-session.</p>
<p>To add your own persistent patterns:</p>
<pre><code>set -U -a sponge_regex_patterns &#39;your-regex-here&#39;</code></pre>
<p>To mark additional variable NAMES as credential-bearing (so Layer 2
scrubs their values), add name tokens — via <code>config-settings</code>
→ Sponge, or directly:</p>
<pre><code>set -U -a __fish_sponge_extra_sensitive ACME_API VAULT_PW</code></pre>
<p>Tokens are folded into the Layer 2 name match case-insensitively as
substrings, so ACME_API also covers ACME_API_KEY. (The match uses
<code>--entire</code> to return the full variable name, so partial-name
tokens dereference the right value.)</p>
<p>The <code>config-settings</code> Sponge page also surfaces sponge's
own tuning variables — sponge_delay, sponge_successful_exit_codes,
sponge_purge_only_on_exit, and sponge_allow_previously_successful — so
they can be changed without typing variable names.</p>
<h2 data-number="12.3" id="bundled-plugin-functionality">Bundled Plugin
Functionality</h2>
<p>The remaining plugin functionality is bundled directly with this
config rather than managed through Fisher. The bundled versions include
customizations for Fish 4.x compatibility and improved behavior that
differ from their upstream releases. Installing them through Fisher
would overwrite these customizations.</p>
<p>Bundled components and their upstream origins:</p>
<pre><code>catppuccin/fish → themes/ + conf.d/theme.fish
PatrickF1/fzf.fish → functions/_fzf_*.fish + conf.d/fzf.fish
franciscolourenco/done → conf.d/done.fish
jorgebucaran/autopair.fish → functions/_autopair_*.fish + conf.d/autopair.fish
nickeb96/puffer-fish → functions/_puffer_fish_*.fish + conf.d/puffer.fish</code></pre>
<p>Do not run <code>fisher install</code> for these — it will overwrite
the customized versions. To update their behavior, edit the relevant
bundled files directly.</p>
<h2 data-number="12.4" id="fish_plugins-manifest">fish_plugins
Manifest</h2>
<p>The <code>fish_plugins</code> file at the config root:</p>
<pre><code>jorgebucaran/fisher Plugin manager itself
meaningful-ooo/sponge Remove failed commands from history</code></pre>
<p>To update all Fisher-managed plugins, run <code>fisher update</code>
or <code>fish-deps update</code> which calls it as its first step.</p>
