Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

/**

* @brief Parse a pacman-style INI config file.
|
|
*
|
|
* @param file path to the config file
|
|
* @param cb callback for key/value pairs
|
|
* @param data caller defined data to be passed to the callback
|
|
*
|
|
* @return the callback return value
|
|
*
|
|
* @note The callback will be called at the beginning of each section with an
|
|
* empty key and value and for each key/value pair.
|
|
*
|
|
* @note If the parser encounters an error the callback will be called with
|
|
* section, key, and value set to NULL and errno set by fopen, fgets, or
|
|
* strdup.
|
|
*
|
|
* @note The @a key and @a value passed to @ cb will be overwritten between
|
|
* calls. The section name will remain valid until after @a cb is called to
|
|
* begin a new section.
|
|
*
|
|
* @note Parsing will immediately stop if the callback returns non-zero.
