If that doesn't yield a file -that exists, the last hyphen and what follows it is stripped. If that doesn't -yield a file that exists, the previous hyphen is stripped, and so on until all -hyphens are gone. For example, if the terminal type is `aaa-48-foo', Emacs -will try first `term/aaa-48-foo.el', then `term/aaa-48.el' and finally -`term/aaa.el'. + When Emacs opens a new terminal, it checks the TERM environment variable to +see what type of terminal the user is running on, searches for an elisp file +named "term/${TERM}.el", and if one exists, loads it. If Emacs finds no +suitable file, then it strips the last hyphen and what follows it from TERM, +and tries again. If that still doesn't yield a file, then the previous hyphen +is stripped, and so on until all hyphens are gone. For example, if the +terminal type is `aaa-48-foo', Emacs will try first `term/aaa-48-foo.el', then +`term/aaa-48.el' and finally `term/aaa.el'. Emacs stops searching at the +first file found, and will not load more than one file for any terminal. Note +that it is not an error if Emacs is unable to find a terminal initialization +file; in that case, it will simply proceed with the next step without loading +any files. + + Once the file has been loaded (or the search failed), Emacs tries to call a +function named `terminal-init-TERMINALNAME' (eg `terminal-init-aaa-48' for the +`aaa-48' terminal) in order to initialize the terminal. Once again, if the +function is not found, Emacs strips the last component of the name and tries +again using the shorter name. This search is independent of the previous file +search, so that you can have terminal initialization functions for a family of +terminals collected in a single file named after the family name, and users +may put terminal initialization functions directly in their .emacs files. + + Note that an individual terminal file is loaded only once in an Emacs +session; if the same terminal type is opened again, Emacs will simply call the +initialization function without reloading the file. Therefore, all the actual +initialization actions should be collected in terminal-init-* functions; the +file should not contain any top-level form that is not a function or variable +declaration. Simply loading the file should not have any side effect. + + Similarly, the terminal initialization function is called only once on any +given terminal, when the first frame is created on it. The function is not +called for subsequent frames on the same terminal. Therefore, terminal-init-* +functions should only modify terminal-local variables (such as +`local-function-key-map') and terminal parameters. For example, it is not +correct to modify frame parameters, since the modifications will only be +applied for the first frame opened on the terminal. + When writing terminal packages, there are some things it is good to keep in mind. ＠＠ -36,7 +70,7 ＠＠ else someday.
