Using NEdit

When you bring up a file in NEdit, the file name is in the top left-hand corner of the window, above the menu. If the file has been changed, it will say (modified) immediately to the right of the file name.

Editing a File

Go to the docs directory on your branch, cd to the desired directory, and bring up the file that you wish to edit:

cd /OpenMDAO/dev/<your_working_directory>/<branch_name>/docs
cd <directory_name>             (e.g., cd user-guide)
nedit <file_name>  &            (Brings up a file in NEdit and runs NEdit in the background.)

Using the Fill Paragraph Option

You can use the Fill Paragraph option on the Edit menu (or type Ctrl+j) to fill text in the paragraph:

  • Select a range of text and then chose Fill Paragraph (or type Ctrl+j). All of the text in the selection will be filled. (A paragraph is the space between blank lines.)
  • Use Fill Paragraph (Ctrl+j) with a rectangular selection of text. NEdit interprets the right edge of the selection (text visible to the right boundary of the window) as the requested wrap margin. Text to the left of the selection is not disturbed, but text to the right of the selection is pulled in to the selected region. This method enables you to fill text to an arbitrary right margin, without going back and forth to the wrap-margin dialog. (In other words, you can make your XWindow the desired size and use this option so your text is visible.)

Moving Text Right or Left

  • To move text to the right:
Highlight a block of text and type Ctrl+0. Keep typing 0 for every space you want the text to move to the right.
  • To move text to the left:
To move text to the left, highlight the text and type Ctrl+9. Keep typing 9 for every space you want the text to move to the left.

An easy way to remember this is that 0 is under the right parenthesis for moving right, while the 9 is under the left parenthesis for moving left. If you hold down the Ctrl key and type a right parens (requiring you to press the shift key simultaneously), the text moves one tab instead of one space.

Launching Spell Check from NEdit

  1. Open the file you want to spell-check and type: nedit <file_name> &

  2. From inside the file, type: Alt+b

    An XWindow titled ispell will appear, and the first potentially misspelled word will be highlighted.

  3. Select the letter or number of the desired option (e.g., Replace All, Ignore All, exit, etc.). You will automatically go to next potentially misspelled word and so on until you come to the end of the file.

  4. When you are finished checking the file, save it, even if you made no changes. (Merely launching ispell is considered a modification to the file.)

Using Line Numbers to Find Sphinx Errors

If you get a Sphinx build error when trying to build your documentation files, your build will fail. Sphinx provides the file name and line number where the error occurs. To find the error:

  1. Type nedit <file_name> & to bring up the file with the error.

  2. On the menu bar, click on Preferences and then on Show Line Numbers.

    You should be able to locate the line with the error and correct the problem.
