With a single $, make will try to expand it as a variable.
|

The scheme syntax highlighting wasn't highlighting base functions, this fixes it.

This should make the list of tests more readable.
|
|
This should make sure that vis always terminates and never hangs
waiting for further input. Lua errors in particular cause a new
window/file to be displayed showing a detailed error message.
Previously only this internal file was closed but the original
file remained open and prevented vis from exiting.
|
|
Custom key bindings might interfere with the tests.
|
|
Analogous to the previous commit.
|
|
Using cpp(1) to remove comments might not have been the best idea,
some versions of clang leave trailing white space intact whereas
gcc removes them. These trailing spaces were wrongly interpreted
as <Space> input. This hopefully fixes the tests on Mac OS X.

Libtermkey tries to write a terminal initialization sequence even when
stdin is not a terminal as is the case when running `vis < /dev/null`
or within the Travis CI environment.
The broken code is in libtermkey's driver-ti.c function `start_driver`:
/* There's no point trying to write() to a pipe */
if(fstat(tk->fd, &statbuf) == -1)
return 0;
if(S_ISFIFO(statbuf.st_mode))
return 1;
Instead they should simply be using isatty(3).
As a workaround we catch the resulting EBADF failure and try to re-open
/dev/tty as stdin. If this fails too (as is the case in the Mac OS X
Travis CI runner) create an abstract termkey instance instead. In this
state vis will not be able to consume any input and will instead spin
with 100% CPU usage in the mainloop. This is solely done to make the Lua
tests, which control vis through other means, work within the Travis CI
environment.

We need to push keys individually to the input queue such that
the state machine can advance and record keys into the operator
macro if necessary.
Previously feeding the following input:
isome text<Escape>.
would not work as expected because the complete key stream
was pushed to the input queue at the same time during which
the operator macro was not yet active. Thus the dot command
at the end would have nothing to repeat.
|
|
Instead of using the keys utility to convert the textual key representation
into something a terminal would send and then pipe it to vis' standard input
use the Lua API to directly feed the keys into vis' input queue.
This has a number of advantages:
- it is less fragile: the keys utility is incomplete and only handles the
most common keys
- it is faster because there is no need to artificially delay input
after an <Escape> key to give vis a chance to distinguish between
a single <Escape> and the start of an escape sequence

If the shell command is omitted, the last shell command (of any type)
is substituted. The most recently used shell command is stored in a
new register currently named `!`.
|
|
As in sam if an empty regex // is provided we substitute in the most
recently used one.
0/regexp///
Will match the second occurrence in the fie.
|
|
Instead we will only run the desired tests from .travis.yml.

Redirecting stdin mimics the environment on Travis CI.
Redirecting stderr should give a nicer test list output,
albeit some useful messages might get lost.

As in visual mode write commands have to be forced with ! if the changes
are destructive i.e. only parts of the file are written.
|
|
|
|
No functional changes.
|
|
Wether `/usr/local/share/vis` or `/usr/share/vis` is used depends
on how the configure script was invoked. However, both are never
used at the same time.
This section should be completely reworked at some point.

Do not initalize curses UI before it is actually needed.
Move vis command line argument parsing logic into main.c.
This fixes `vis -v` output and exit status.
Fix #351
|
|
Add another layer of indirection, move actual event generation
code to a dedicated function.
|
|
In preparation to move argument parsing code out of vis.c.

No longer accept "no" prefix for boolean options. Reject too many option
values (use proper quoting to specify values containing spaces).
|

We first try $SHELL and then fall back to the shell field of the password
file entry (/etc/passwd).
|
|
:0 < echo "Should be inserted at the start of the file"
:1 < echo "Should replace the first line"
|
|
|
|
|
|
Also rename underlying C code.
|
|
It was the only command option which needed `=` to assign a value to.
This unifies the argument parsing logic and adds the possibility to
specify a per-option help text.
You might want to adapt your visrc.lua configuration accordingly.
