+SprigX are extensions to https://masterminds.github.io/sprig/[the `sprig` library^] (https://pkg.go.dev/github.com/Masterminds/sprig/v3[Go docs^]).
+
+They provide functions that offer more enriched use cases and domain-specific data.

+
+[id="fn"]
+== Functions
+Expect this list to grow over time, and potentially more frequently than the `sprigx` functions.
+
+[id="fn_sys"]
+=== System/OS/Platform
+
+[id="fn_sys_arch"]
+==== `sysArch`
+Returns the https://pkg.go.dev/runtime#GOARCH[`runtime.GOARCH`^] constant.
+
+[id="fn_sys_numcpu"]
+==== `sysNumCpu`
+Returns the value from https://pkg.go.dev/runtime#NumCPU[`runtime.NumCPU`^].
+
+[id="fn_sys_os"]
+==== `sysOsName`
+Returns the https://pkg.go.dev/runtime#GOOS[`runtime.GOOS`^] constant.
+
+[id="fn_sys_rntm"]
+==== `sysRuntime`
+This function returns a `map[string]string` of various information from the https://pkg.go.dev/runtime[`runtime` stdlib library^].
+
+Specifically, the following are returned.
+
+[TIP]
+====
+The value type is a direct link to the `runtime` documentation providing more detail about the associated value.
+
+Because all values are mapped as strings, they can be converted back to their native type via e.g. the https://masterminds.github.io/sprig/conversion.html[Sprig conversion functions^] if necessary.
+====
+
+.`sysRuntime` Values
+[cols="^.^3m,^.^3",options="header"]
+|===
+| Key | Value Type
+
+| compiler | https://pkg.go.dev/runtime#Compiler[string^]
+| arch | https://pkg.go.dev/runtime#GOARCH[string^]
+| os | https://pkg.go.dev/runtime#GOOS[string^]
+| maxprocs | https://pkg.go.dev/runtime#GOMAXPROCS[int^] footnote:[For safety concerns, `sprigx` does not allow *setting* `GOMAXPROCS`, this value only contains the *current* `GOMAXPROCS` value.]
+| cpu_cnt | https://pkg.go.dev/runtime#NumCPU[int^]
+| num_cgo | https://pkg.go.dev/runtime#NumCgoCall[int^]
+| num_go | https://pkg.go.dev/runtime#NumGoroutine[int^]
+| go_ver | https://pkg.go.dev/runtime#Version[string^]
+|===
+
+As a convenience, some of these values also have their own dedicated functions as well:
+
+* <<fn_sys_arch>>
+* <<fn_sys_numcpu>>
+* <<fn_sys_os>>
+
+[id="fn_path"]
+=== Paths
+
+[id="fn_path_gnrc"]
+==== Generic
+These operate similar to https://pkg.go.dev/path[the `path` stdlib library^] and use a fixed `/` path separator.
+
+[id="fn_path_gnrc_pj"]
+===== `pathJoin`
+`pathJoin` operates *exactly* like https://pkg.go.dev/path#Join[`path.Join`^] in stdlib.
+
+[WARNING]
+====
+If you are joining paths in a pipeline, you almost assuredly want <<fn_path_gnrc_ppj>> or <<fn_path_gnrc_pspj>> instead unless you are explicitly *appending* a pipeline result to a path.
+====
+
+[source,gotemplate]
+----
+{{- pathJoin "a" "b" "c" }}
+{{- pathJoin "/" "a" "b" "c" }}
+{{- pathJoin "/a/b" "c" }}
+----
+
+renders as:
+
+[source,text]
+----
+a/b/c
+/a/b/c
+/a/b/c
+----
+
+[id="fn_path_gnrc_ppj"]
+===== `pathPipeJoin`
+`pathPipeJoin` operates like <<fn_path_gnrc_pj>> with one deviation: the root/base path is expected to be *last* in the arguments.
+
+This makes it much more suitable for use in template pipelines, as the previous value in a pipeline is passed in as the last element to the next pipe function.
+
+[source,gotemplate]
+----
+{{- $myBase := "/a" -}}
+{{- pathPipeJoin "b" "c" "a" }}
+{{- pathPipeJoin "a" "b" "c" "/" }}
+{{- $myBase | pathPipeJoin "b" "c" }}
+----
+
+renders as:
+
+[source,text]
+----
+a/b/c
+/a/b/c
+/a/b/c
+----
+
+[id="fn_path_gnrc_psj"]
+===== `pathSliceJoin`
+`pathSliceJoin` joins a slice of path segment strings (`[]string`) instead of a variadic sequence of strings.
+
+[TIP]
+====
+The `splitList` function shown below is from the https://masterminds.github.io/sprig/string_slice.html[`sprig` string slice functions^].
+====
+
+[source,gotemplate]
+----
+{{- $myList := "a,b,c" | splitList "," -}}
+{{- $myList | pathSliceJoin }}
+{{- ("a,b,c" | splitList ",") | pathSliceJoin }}
+{{- ("/,a,b,c" | splitList ",") | pathSliceJoin }}
+----
+
+renders as:
+
+[source,text]
+----
+a/b/c
+a/b/c
+/a/b/c
+----
+
+[id="fn_path_gnrc_pspj"]
+===== `pathSlicePipeJoin`
+`pathSlicePipeJoin` operates like <<fn_path_gnrc_ppj>> in that it is suitable for pipeline use in which the root/base path is passed in from the pipeline, but it is like <<fn_path_gnrc_psj>> in that it then also accepts a slice of path segments (`[]string`) to append to that base path.
+
+[TIP]

+[id="fn_path_gnrc_psubj"]
+===== `pathSubJoin`
+`pathSubJoin` operates like <<fn_path_gnrc_pj>> but it expects an explicit root/base path.
+
+The pipeline-friendly equivalent of this is <<fn_path_gnrc_ppj>>.
+
+[source,gotemplate]
+----

+
+[id="fn_path_os"]
+==== OS/Platform-Tailored
+These operate similar to https://pkg.go.dev/path/filepath[the `path/filepath` stdlib library^], and use the OS-specific https://pkg.go.dev/os#PathSeparator[`os.PathSeparator`^].
+
+[WARNING]
+====
+Take special note of the oddness around specifying Windows paths and drive letters in e.g. <<fn_path_os_pj>>!
+
+It is recommended to make use of <<fn_sys_os>> to conditionally format path bases/roots if needed.
+====
+
+[id="fn_path_os_pj"]
+===== `osPathJoin`
+`osPathJoin` operates *exactly* like https://pkg.go.dev/path/filepath#Join[`path/filepath.Join`^] in stdlib.
+
+[WARNING]
+====
+If you are joining paths in a pipeline, you almost assuredly want <<fn_path_os_ppj>> or <<fn_path_os_pspj>> instead unless you are explicitly *appending* a pipeline result to a path.
+====
+
+[source,gotemplate]

+`osPathPipeJoin` operates like <<fn_path_gnrc_ppj>> (except using OS-specific path separators).
+
+This makes it much more suitable for use in template pipelines, as the previous value in a pipeline is passed in as the last element to the next pipe function.
+

+[id="fn_str"]
+=== Strings
+
+[id="fn_str_extindent"]
+==== `extIndent`
+`extIndent` allows for a MUCH more flexible indenter than the `sprig` `indent` function.
+
+It works with both Windows (`\r\n`) and POSIX (`\n`) linebreaks.
+
+[TIP]
+====
+If `<indentString>` is set to `\n` and `<levels>` is always set to `1`, this function can even be used to doubelspace text!
+====
+
+It has quite a few arguments, however:
+
+[source,gotemplate]
+----
+{{ extIndent <levels> <skipFirst> <skipEmpty> <skipWhitespace> <indentString> <input> }}
+----
+
+Where:
+
+* `<levels>`: The level of indentation for the text. If less than or equal to `0`, `extIndent` just returns `<input>` as-is and NO-OPs otherwise.
+* `<skipFirst>`: If true, skip indenting the first line. This is particularly handy if you like to visually align your function calls in your templates.
+* `<skipEmpty>`: If true, do not add an indent to *empty* lines (where an "empty line" means "only has a linebreak").
+* `<skipWhitespace>`: If true, do not add an indent to lines that *only* consist of whitespace (spaces, tabs, etc.) and a linebreak.
+* `<indentString>`: The string to use as the "indent character". This can be any string, such as `" "`, `"\t"`, `"."`, `"|"`, `"=="` etc.
+* `<input>`: The text to be indented. Because it is the last argument, `extIndent` works with pipelined text as well.

+=== Debugging
+
+[id="fn_dbg_dump"]

+The `dump` function calls https://pkg.go.dev/github.com/davecgh/go-spew/spew#Sdump[the `Sdump` function^] from https://github.com/davecgh/go-spew[`go-spew`] (https://pkg.go.dev/github.com/davecgh/go-spew/spew[`github.com/davecgh/go-spew/spew`^]) for whatever object(s) is/are passed to it.

+# What is SprigX?
+
+SprigX are extensions to [the `sprig`
+library](https://masterminds.github.io/sprig/) ([Go
+docs](https://pkg.go.dev/github.com/Masterminds/sprig/v3)).
+
+They provide functions that offer more enriched use cases and
+domain-specific data.
+
+# How do I Use SprigX?

+If a `<template>.FuncMap` is added via `.Funcs()` **after** template

+# Functions
+
+Expect this list to grow over time, and potentially more frequently than

+
+## System/OS/Platform
+
+### `sysArch`
+
+Returns the [`runtime.GOARCH`](https://pkg.go.dev/runtime#GOARCH)
+constant.
+
+### `sysNumCpu`
+
+Returns the value from
+[`runtime.NumCPU`](https://pkg.go.dev/runtime#NumCPU).
+
+### `sysOsName`
+
+Returns the [`runtime.GOOS`](https://pkg.go.dev/runtime#GOOS) constant.
+
+### `sysRuntime`
+
+This function returns a `map[string]string` of various information from
+the [`runtime` stdlib library](https://pkg.go.dev/runtime).
+
+Specifically, the following are returned.
+
+The value type is a direct link to the `runtime` documentation providing
+more detail about the associated value.
+
+Because all values are mapped as strings, they can be converted back to
+their native type via e.g. the [Sprig conversion
+functions](https://masterminds.github.io/sprig/conversion.html) if
+necessary.

+## Paths
+
+### Generic
+
+These operate similar to [the `path` stdlib
+library](https://pkg.go.dev/path) and use a fixed `/` path separator.
+
+#### `pathJoin`
+
+`pathJoin` operates **exactly** like
+[`path.Join`](https://pkg.go.dev/path#Join) in stdlib.
+
+If you are joining paths in a pipeline, you almost assuredly want
+[](#fn_path_gnrc_ppj) or [](#fn_path_gnrc_pspj) instead.
+
+    {{- pathJoin "a" "b" "c" }}
+    {{- pathJoin "/" "a" "b" "c" }}
+    {{- pathJoin "/a/b" "c" }}
+
+renders as:
+
+    a/b/c
+    /a/b/c
+    /a/b/c
+
+#### `pathPipeJoin`
+
+`pathPipeJoin` operates like [](#fn_path_gnrc_pj) with one deviation:
+the root/base path is expected to be **last** in the arguments.
+
+This makes it much more suitable for use in template pipelines, as the
+previous value in a pipeline is passed in as the last element to the
+next pipe function.
+
+    {{- $myBase := "/a" -}}
+    {{- pathPipeJoin "b" "c" "a" }}
+    {{- pathPipeJoin "a" "b" "c" "/" }}
+    {{- $myBase | pathPipeJoin "b" "c" }}
+
+renders as:
+
+    a/b/c
+    /a/b/c
+    /a/b/c
+
+#### `pathSliceJoin`
+
+`pathSliceJoin` joins a slice of path segment strings (`[]string`)
+instead of a variadic sequence of strings.
+
+The `splitList` function shown below is from the [`sprig` string slice
+functions](https://masterminds.github.io/sprig/string_slice.html).
+
+    {{- $myList := "a,b,c" | splitList "," -}}
+    {{- $myList | pathSliceJoin }}
+    {{- ("a,b,c" | splitList ",") | pathSliceJoin }}
+    {{- ("/,a,b,c" | splitList ",") | pathSliceJoin }}
+
+renders as:
+
+    a/b/c
+    a/b/c
+    /a/b/c
+
+#### `pathSlicePipeJoin`
+
+`pathSlicePipeJoin` operates like [](#fn_path_gnrc_ppj) in that it is
+suitable for pipeline use in which the root/base path is passed in from
+the pipeline, but it is like [](#fn_path_gnrc_psj) in that it then also
+accepts a slice of path segments (`[]string`) to append to that base
+path.
+
+The `splitList` function shown below is from the [`sprig` string slice
+functions](https://masterminds.github.io/sprig/string_slice.html).
+
+    {{- $myBase := "/a" -}}
+    {{- $myList := "b,c,d" | splitList "." -}}
+    {{- pathSlicePipeJoin $myList $myBase }}
+    {{- $myBase | pathSlicePipeJoin $myList }}
+
+renders as:
+
+    /a/b/c
+    /a/b/c
+
+#### `pathSubJoin`
+
+`pathSubJoin` operates like [](#fn_path_gnrc_pj) but it expects an
+explicit root/base path.
+
+The pipeline-friendly equivalent of this is [](#fn_path_gnrc_ppj).
+
+    {{- pathSubJoin "/a/b" "c" }}
+    {{- pathSubJoin "/" "a" "b" "c" }}
+    {{- "c" | pathSubJoin "/" "a" "b" }}
+
+renders as:
+
+    /a/b/c
+    /a/b/c
+    /a/b/c
+
+### OS/Platform-Tailored
+
+These operate similar to [the `path/filepath` stdlib
+library](https://pkg.go.dev/path/filepath), and use the OS-specific
+[`os.PathSeparator`](https://pkg.go.dev/os#PathSeparator).
+
+Take special note of the oddness around specifying Windows paths and
+drive letters in e.g. [](#fn_path_os_pj)!
+
+It is recommended to make use of [](#fn_sys_os) to conditionally format
+path bases/roots if needed.
+
+#### `osPathJoin`
+
+`osPathJoin` operates **exactly** like
+[`path/filepath.Join`](https://pkg.go.dev/path/filepath#Join) in stdlib.
+
+If you are joining paths in a pipeline, you almost assuredly want
+[](#fn_path_os_ppj) or [](#fn_path_os_pspj) instead.
+
+    {{- osPathJoin "a" "b" "c" }}
+    {{- osPathJoin "/" "a" "b" "c" }}
+    {{- osPathJoin "C:\\" "a" "b" "c" }}
+    {{- osPathJoin "C:" "a" "b" "c" }}

+## Strings
+
+### `extIndent`
+
+`extIndent` allows for a MUCH more flexible indenter than the `sprig`
+`indent` function.
+
+It works with both Windows (`\r\n`) and POSIX (`\n`) linebreaks.
+
+It has quite a few arguments, however:
+
+    {{ extIndent <levels> <skipFirst> <skipEmpty> <skipWhitespace> <indentString> <input> }}
+
+Where:
+
+-   `<levels>`: The level of indentation for the text. If less than or
+    equal to `0`, `extIndent` just returns `<input>` as-is and NO-OPs
+    otherwise.
+
+-   `<skipFirst>`: If true, skip indenting the first line. This is
+    particularly handy if you like to visually align your function calls
+    in your templates.
+
+-   `<skipEmpty>`: If true, do not add an indent to **empty** lines
+    (where an "empty line" means "only has a linebreak").
+
+-   `<skipWhitespace>`: If true, do not add an indent to lines that
+    **only** consist of whitespace (spaces, tabs, etc.) and a linebreak.
+
+-   `<indentString>`: The string to use as the "indent character". This
+    can be any string, such as `" "`, `"\t"`, `"."`, `"|"`, `"=="` etc.
+
+-   `<input>`: The text to be indented. Because it is the last argument,
+    `extIndent` works with pipelined text as well.
