Function Documentation

mutt_make_version()

const char* mutt_make_version

(

void

)

Generate the NeoMutt version string.

Return values

ptr	Version string

Note

This returns a pointer to a static buffer

Definition at line 1476 of file muttlib.c.

{
  static char vstring[256];
  snprintf(vstring, sizeof(vstring), "NeoMutt %s%s", PACKAGE_VERSION, GitVer);
  return vstring;
}

Here is the caller graph for this function:

store_backend_list()

const char* store_backend_list

(

void

)

Get a list of backend names.

Return values

ptr	Comma-space-separated list of names

The caller should free the string.

Definition at line 84 of file store.c.

{
  char tmp[256] = { 0 };
  const struct StoreOps **ops = StoreOps;
  size_t len = 0;
 
  for (; *ops; ops++)
  {
    if (len != 0)
    {
      len += snprintf(tmp + len, sizeof(tmp) - len, ", ");
    }
    len += snprintf(tmp + len, sizeof(tmp) - len, "%s", (*ops)->name);
  }
 
  return mutt_str_dup(tmp);
}

Here is the caller graph for this function:

store_compress_list()

const char* store_compress_list

(

void

)

print_compile_options()

static void print_compile_options ( struct CompileOptions *  co, FILE *  fp  )

static

Print a list of enabled/disabled features.

Parameters

co	Array of compile options
fp	file to write to

Two lists are generated and passed to this function:

One list which just uses the configure state of each feature. One list which just uses feature which are set to on directly in NeoMutt.

The output is of the form: "+enabled_feature -disabled_feature" and is wrapped to SCREEN_WIDTH characters.

Definition at line 329 of file version.c.

    if ((used + len) > SCREEN_WIDTH)
    {
      used = 2;
      fprintf(fp, "\n  ");
    }
    used += len;
    const char *fmt = "?%s ";

}

Here is the caller graph for this function:

rstrip_in_place()

static char* rstrip_in_place ( char *  s )

static

Parameters

s	String to be modified

Return values

ptr	The modified string

The string has its last carriage return set to NUL.

{
  if (!s)
    return NULL;
 
  char *p = &s[strlen(s)];

feature_enabled()

bool feature_enabled

(

const char *

name

)

Test if a compile-time feature is enabled.

Parameters

name	Compile-time symbol of the feature

Return values

true	Feature enabled
false	Feature not enabled, or not compiled in

Many of the larger features of neomutt can be disabled at compile time. They define a symbol and use ifdef's around their code. The symbols are mirrored in "CompileOptions comp_opts[]" in this file.

This function checks if one of these symbols is present in the code.

These symbols are also seen in the output of "neomutt -v".
