|
|
|
98

99 The second element is the string handed to the shell after being

104 Several such hooks has been defined:
|
|
|
105
|
|
|
106 TeX-run-command: Start up the process and show the output in a
|
|
|
107 separate buffer. Check that there is not two commands running for the
|
|
|
108 same file. Return the process object.
|
|
|
109
|
|
|
110 TeX-run-format: As TeX-run-command, but assume the output is created
|
|
|
111 by a TeX macro package. Return the process object.
|
|
|
112
|
|
|
113 TeX-run-TeX: For TeX output.
|
|
|
114
|
|
|
115 TeX-run-LaTeX: For LaTeX output.
|
|
|
116
|
|
|
117 TeX-run-interactive: Run TeX or LaTeX interactively.
|
|
|
118
|
|
|
119 TeX-run-BibTeX: For BibTeX output.
|
|
|
120
|
|
|
121 TeX-run-compile: Use `compile' to run the process.
|
|
|
122
|
|
|
123 TeX-run-shell: Use `shell-command' to run the process.
|
|
|
124
|
|
|
125 TeX-run-discard: Start the process in the background, discarding its
|
|
|
126 output.
|
|
|
127
|
|
|
128 TeX-run-background: Start the process in the background, show output
|
|
|
129 in other window.
|
|
|
130
|
|
|
131 TeX-run-dviout: Special hook for the Japanese dviout previewer for
|
|
|
132 PC-9801.

|
|
|
135 name of the command, the command string, and the name of the file to
|
|
|
136 process. It might be useful to use TeX-run-command in order to
|
|
|
137 create an asynchronous process.

140 modify the expanded string.
