vid doesn't build

[pepa65]

On Ubuntu 18.04 (mentioned dependencies installed)
v version: V 0.1.22 be4eaa6
Output of v .:

warning: use "_linux.v" file name instead of "/home/pp/git/v/vlib/ui/ui_lin.v"
./vid.v:1152:34: `vid` is declared as mutable, but it was never changed
 1150| 
 1151| // Find current word under cursor
 1152| fn (vid mut Vid) word_under_cursor() string {
                                        ^
 1153| 	line := vid.view.line()
 1154| 	// First go left

Looks like this has been fixed. Can you confirm @pepa65?

[pepa65]

After pulling v again from current, making and installing that, I now get as output of v .:

./vid.v:15:3: cannot import module "ui" (not found)
   13| 	os
   14| 	time
   15| 	ui
         ^

[watzon]

Did you pull the most recent version of vid as well? Because that line has been changed.

[pepa65]

Sorry, I forgot... Now I'm getting:

Gonna need the full error trace. Build with -g.

I did a v up and tried again v . on vid:

warning: ./vid.v:1819:1: the following imports were never used: 
 * uiold
 -lglfw
collect2: error: ld returned 1 exit statusV error: C error. This should never happen.

This was so different from the last try I thought I'd post again.

[medvednikov]

If you follow instructions in the readme, everything will work.

Install glfw.

[pepa65]

dpkg -l |grep glfw:

ii  libglfw3:amd64                         3.2.1-1                                         amd64        portable library for OpenGL, window and input (x11 libraries)
ii  libglfw3-dev:amd64                     3.2.1-1                                         amd64        portable library for OpenGL, window and input (development files)

[pepa65]

But just now trying v . on vid gives:

warning: ./vid.v:1819:1: the following imports were never used: 
 * uiold

And vid gets built. Can't use it yet though, it's unresponsive.

[pepa65]

Usually it's not good to close an issue before you get confirmation that it's working.

[medvednikov]

What did you do differently to make it build?

[pepa65]

I did cd git/vid and then v .
But the editor doesn't do anything. I think I'll leave you to work on it for a bit, because I don't know how I can help. I think v looks fantastic, and I'm really looking forward to using it!

[medvednikov]

Try running it with ./vid path_to_git_project and use ctrl-p to navigate files.

[pepa65]

./vid .

create window wnd=0x559d15d47fb0 ptr==0x559d15d46d10
Trying to load font from RobotoMono-Regular.ttf
["./vid", "."]
PATH="." cur_dir="/home/pp/git/vid"
load session "/home/pp/.vid/session"
Segmentation fault

(There is no /home/pp/.vid/session.)

[pepa65]

If I copy the file RobotoMono-Regular.ttf into the vid directory and try to open a single file, it works:
./vid timer.v
And I can navigate the file and insert/delete etc.

[watzon]

./vid .

create window wnd=0x559d15d47fb0 ptr==0x559d15d46d10
Trying to load font from RobotoMono-Regular.ttf

I've gotten this too actually, when trying to open a path. Works fine with a single file.
