Detailed Description

Syntax checker and auto-fixer tool for Fun source files.

Definition in file funstx.c.

Function Documentation

apply_fixes()

char * apply_fixes ( const char * src, size_t len, size_t * out_len )

static

Apply conservative style/syntax auto-fixes to a Fun source buffer.

Fixes include:

• Normalize indentation to 2 spaces (tabs become 2 spaces per tab)
• Convert CRLF/CR line endings to LF
• Trim trailing spaces on each line
• Ensure the file ends with a single LF
• Normalize identifiers 'sint8/16/32/64' to 'int8/16/32/64' at word boundaries

Returns a newly allocated buffer containing the fixed content and writes the resulting length to out_len. Caller must free the returned buffer.

Parameters

src	Input buffer.
len	Input length.
out_len	Output length of fixed buffer.

Returns

Newly malloc'd fixed buffer on success, or NULL on OOM.

Definition at line 116 of file funstx.c.

is_word()

int is_word ( int c )

static

Determine whether a character is an identifier constituent.

Parameters

c	Character code (unsigned char promoted to int).

Returns

Non-zero if c is '_' or an alphanumeric character.

Definition at line 94 of file funstx.c.

main()

int main	(	int	argc,
		char **	argv )

Entry point for funstx.

Parses flags, optionally applies in-place fixes (–fix), and validates each provided Fun source file by attempting to parse it. With –quiet, only errors are printed; otherwise, prints "OK" for valid files.

Parameters

argc	Argument count.
argv	Argument vector.

Returns

0 if all files are valid (and fixes succeeded if requested), non-zero otherwise.

Definition at line 299 of file funstx.c.

read_all()

int read_all ( const char * path, char ** out_buf, size_t * out_len )

static

Read entire file into a newly allocated buffer.

The returned buffer is NUL-terminated for convenience. Caller must free it.

Parameters

path	Path to file to read.
out_buf	Output pointer to receive malloc'd buffer.
out_len	Output length of the file (without the terminating NUL).

Returns

1 on success, 0 on failure.

Definition at line 41 of file funstx.c.

usage()

void usage ( const char * prog )

static

Print command-line usage for the funstx tool to stderr.

Parameters

prog	Program name (argv[0]). May be NULL.

Definition at line 27 of file funstx.c.

write_all()

int write_all ( const char * path, const char * buf, size_t len )

static

Overwrite a file with the provided buffer.

Parameters

path	Target file path.
buf	Buffer to write.
len	Number of bytes to write.

Returns

1 on success, 0 otherwise.
