## Documentation

Programs for creating and viewing documentation.

To facilitate navigating in this list, projects are categorized by their purpose, authorship, and current state. Each project entry lists the categories it pertains to. Clicking on a category name will bring a listing of all projects in that category.

Additionally, a list of related projects is provided where applicable. Each element in that list is a link to the corresponding project entry.

Clicking on a project's name will bring this project's entry as a separate page (a permalink).

Hovering your mouse over the version information of a project shows the list of changes introduced by that version.

Sort controls below allow you to order the list either lexicographically or by the most recent release date, in both directions.

Using the Search control, you can select projects by name. Shell-style globbing patterns (wildcards) are accepted.

### xenv

Version: 3.1  —  2022-04-01
* New feature-control options

** -Wno-escape

The '-Wno-escape' option disables special handling of backslash in
free context.  For example, with this option in effect, the variable
$HOME will be expanded in the following text The \$HOME always expands

The '-Wno-escape' option does not affect expansion of default values
in variable substitutions.  For example, in the text below, the backslash
prevents the

${HOME:+"The variable \$HOME is set"}

** -Wminimal

This option disables all other features and enforces '$ENV' as environment meta-variable. In terms of xenv options, it is a shortcut for: -Wno-command -Wno-comment -Wno-directive -Wno-quote \ -Wno-escape -e ENV  Category: Description: Xenv is a text preprocessor. It reads input from files (or the standard input, if none are supplied) and prints it on the standard output, replacing references to environment variables with their actual values. Variables are referenced using POSIX-compatible shell syntax: $NAME, ${NAME}, ${NAME:-word}, ${NAME+=word}, ${NAME:=word}, ${NAME:?word}. A special ternary construct is provided: ${NAME:|word1|word2}, which substitutes the expansion of word1 if NAME is set and the expansion of word2 otherwise. Conditional preprocessor statements are provided, that allow parts of input to be excluded depending on whether a variable is set.
