Configuration for ffmt formatting.

Defaults match MFC’s current style conventions. Config is loaded from ffmt.toml or [tool.ffmt] in pyproject.toml, searched upward from the formatted file’s directory.

Fields

indent_width: usize

Indentation width in spaces.

line_length: usize

Maximum line length before splitting.

keyword_case: KeywordCase

Keyword case normalization mode.

normalize_keywords: Toggle

Normalize compound keywords (enddo -> end do).

indent_fypp: bool

Indent Fypp preprocessor blocks.

indent_module: bool

Indent body of module/program.

named_ends: Toggle

Add procedure/module name to bare end statements.

align_declarations: bool

Align :: in consecutive declaration blocks.

align_comments: bool

Align !< inline Doxygen comments in declaration blocks.

compact_declarations: Toggle

Remove blank lines between consecutive declarations.

compact_use: Toggle

Remove blank lines between consecutive use statements.

unicode_to_ascii: bool

Replace Unicode Greek/math symbols with LaTeX in comments.

rewrap_comments: Toggle

Re-wrap long comments at line-length.

rewrap_code: Toggle

Re-wrap long code lines at line-length.

space_after_comment: Toggle

Ensure space after ! in regular comments.

collapse_double_spaces: bool

Collapse double spaces to single in code regions.

keyword_paren_space: Toggle

Add space between keywords and ( (if, call, allocate, etc.).

fypp_list_commas: Toggle

Normalize comma spacing in Fypp ‘[…]’ list arguments.

end_of_line: EndOfLine

Line ending normalization: “lf”, “crlf”, or “preserve”.

Split semicolon-separated statements onto separate lines. Accepts true/false/“preserve”.

align_ampersand: Toggle

Align trailing & continuation markers at column limit. Accepts true/false/“preserve”.

align_assignments: Toggle

Align = in consecutive assignment statements. Accepts true/false/“preserve”.

use_formatting: Toggle

whitespace: WhitespaceConfig

Whitespace rules.

files: FilesConfig

File handling.

Implementations

impl Config

pub fn find_and_load(start_dir: &Path) -> Self

Search upward from start_dir for ffmt.toml or pyproject.toml with [tool.ffmt]. Returns default config if nothing found.

pub fn from_file(path: &Path) -> Result<Self, String>

Load from a specific config file path.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

where Config: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
