How-to for Updating GRASS Manual Pages
This page will provide general step-by-step instructions for updating and improving GRASS manual pages. Feel free to update and improve this page as well! See also SUBMITTING_DOCS in the source code.
As an example, the vector program v.in.ascii will be used to illustrate the steps required to update its manual page. These steps can then be generalized for your case.
- To begin, you must obtain the latest GRASS source code from the CVS repositories. Detailed instructions on how to do so can be found here.
- Once you have downloaded the CVS source code, open a terminal and change directory to where the source for a specific GRASS module is located - in this example, something like:
- Open a text editor and make your edits to description.html. Save your edits by overwriting the original description.html.
- Within a terminal, create a 'unified diff' (a standard way to show changes between two versions of a file) of the GRASS CVS repository version of description.html and your newly edited description.html:
cvs diff -u description.html > v.in.ascii.description.patch
The "diff -u" command will create a report in v.in.ascii.description.patch which shows any differences between the version of description.html still on the CVS server and your edited version; a '+' at the beginning of each line denotes edits and additions you have made, and a '-' at the beginning of each line denotes lines removed from the original description.html. The exact name of your patch file is arbitrary, but should be as descriptive as possible as in the above example.
The output of the diff -u should look something like this (the exact contents will of course depend on whatever changes you made to the file):

- Images can also be inserted in the html help page. See v.voronoi for an example. Note that images won't show up in the Grass manual pages (which are generated from the HTML), so they shouldn't be considered a substitute for an adequate textual description. Be sure to also send the image (preferably png format) along with your documentation patch.
- The following html codes are understood to some extent by g.html2man (brackets removed): A, B, BLINK, BODY, BR, CODE, DD, DL, DT, EM, H2, H3, H4, HEAD, HEADER, HR, I, IMG, LI, OL, P, PRE, SUP, TABLE, TD, TH, TITLE, TR, UL.
- Email a GRASS developer your description.html.patch for review as an attachment, along with a brief explanation why it is required. Please post a general message about your documentation update to the GRASS Developer's List before sending your patch to anyone in particular.
