If the function name (or expression) in a function call or declaration
is itself so long that even the first argument doesn't fit after it on
the same line, or if that would leave so little space that it would be
silly to try to wrap all the run-on lines into a tall thin column,
then I used to do this
ludicrously_long_function_name
(arg1, arg2, arg3);
and now prefer this
ludicrously_long_function_name(
arg1, arg2, arg3);
I picked up the habit from Python, where the latter idiom is required
by Python's syntactic significance of newlines (you can write the
former if you use a backslash-continuation, but pretty much everyone
seems to agree that that's much uglier). But I've found it works well
in C as well: it makes it more obvious that the previous line is
incomplete, it gives you a tiny bit more space to wrap the following
lines into (the old idiom indents the _third_ line one space beyond
the second), and I generally turn out to agree with the knock-on
indentation decisions made by at least Emacs if you do it in the
middle of a complex expression. Plus, of course, using the _same_
idiom between C and Python means less state-switching.
So, while I'm making annoying indentation changes in general, this
seems like a good time to dig out all the cases of the old idiom in
this code, and switch them over to the new.
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Then, to install in the simplest way on Linux or Mac:
cmake --build . --target install
On Unix, pterm would like to be setuid or setgid, as appropriate, to
permit it to write records of user logins to /var/run/utmp and
/var/log/wtmp. (Of course it will not use this privilege for
anything else, and in particular it will drop all privileges before
starting up complex subsystems like GTK.) The cmake install step
doesn't attempt to add these privileges, so if you want user login
recording to work, you should manually ch{own,grp} and chmod the
pterm binary yourself after installation. If you don't do this,
pterm will still work, but not update the user login databases.
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
