Setting Indentation Spacing

Use the statement-indent:n option to set the indentation of all statements to n, an integer. The default is 4 spaces of indentation. To set the indentation for expressions, use expression-indent:n. This sets the number of spaces of indentation to n, an integer, and defaults to two spaces of indentation.

Default Indentation

Not specifying indent formatting options uses the default of four spaces for statements and two spaces for expressions. For example, using

• mcc -xg gasket
  

generates the following code segment:

• 0        1         2         3         4         5         6         7         8
  12345678901234567890123456789012345678901234567890123456789012345678901234567890
  
  void mlxGasket(int nlhs, mxArray * plhs[], int nrhs, mxArray * prhs[]) {
      mxArray * mprhs[1];
      mxArray * mplhs[1];
      int i;
      if (nlhs > 1) {
          mlfError(
            mxCreateString(
              "Run-time Error: File: gasket Line: 1 Column: "
              "1 The function \"gasket\" was called with mor"
              "e than the declared number of outputs (1)."),
            NULL);
      }
      if (nrhs > 1) {
          mlfError(
            mxCreateString(
              "Run-time Error: File: gasket Line: 1 Column: "
              "1 The function \"gasket\" was called with mor"
              "e than the declared number of inputs (1)."),
            NULL);
      }
      for (i = 0; i < 1; ++i) {
          mplhs[i] = NULL;
      }
      for (i = 0; i < 1 && i < nrhs; ++i) {
          mprhs[i] = prhs[i];
      }
      for (; i < 1; ++i) {
          mprhs[i] = NULL;
      }
      mlfEnterNewContext(0, 1, mprhs[0]);
      mplhs[0] = Mgasket(nlhs, mprhs[0]);
      mlfRestorePreviousContext(0, 1, mprhs[0]);
      plhs[0] = mplhs[0];
  }
  

Modified Indentation

This example shows the same segment of code using a statement indentation of two and an expression indentation of one:

• mcc -F statement-indent:2 -F expression-indent:1 -xg gasket
  

generates the following code segment:

• 0        1         2         3         4         5         6         7         8
  12345678901234567890123456789012345678901234567890123456789012345678901234567890
  
  void mlxGasket(int nlhs, mxArray * plhs[], int nrhs, mxArray * prhs[]) {
    mxArray * mprhs[1];
    mxArray * mplhs[1];
    int i;
    if (nlhs > 1) {
      mlfError(
       mxCreateString(
        "Run-time Error: File: gasket Line: 1 Column: 1 The function \"gaske"
        "t\" was called with more than the declared number of outputs (1)."),
       NULL);
    }
    if (nrhs > 1) {
      mlfError(
       mxCreateString(
        "Run-time Error: File: gasket Line: 1 Column: 1 The function \"gaske"
        "t\" was called with more than the declared number of inputs (1)."),
       NULL);
    }
    for (i = 0; i < 1; ++i) {
      mplhs[i] = NULL;
    }
    for (i = 0; i < 1 && i < nrhs; ++i) {
      mprhs[i] = prhs[i];
    }
    for (; i < 1; ++i) {
      mprhs[i] = NULL;
    }
    mlfEnterNewContext(0, 1, mprhs[0]);
    mplhs[0] = Mgasket(nlhs, mprhs[0]);
    mlfRestorePreviousContext(0, 1, mprhs[0]);
    plhs[0] = mplhs[0];
  }
