:Vinfo printf* do not works

[ling-zhou]

:Vinfo libc works

but :Vinfo printf do not works, this is error message: [Vinfo] Invalid DOC: printf (No repo created)

Weird, I just tried it and it works fine for me. What Vim version are you using? :version

Also, Try running :VinfoClean to purge vinfo's repos and then try :Vinfo printf again.

$ vim --version VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Mar 21 2018 11:40:10) Included patches: 1-1625

Tried :VinfoClean, and still do not works for :Vinfo printf, :Vinfo scanf, etc.

I'm unable to reproduce the issue, but the only thing i can think of is that info itself doesn't have the docs, does info printf or info scanf work? Also, what is the output of info --version?

12.12.7 Formatted Output Functions

This section describes how to call printf' and related functions. Prototypes for these functions are in the header filestdio.h'. Because these functions take a variable number of arguments, you must declare prototypes for them before using them. Of course, the easiest way to make sure you have all the right prototypes is to just include `stdio.h'.

-- Function: int printf (const char *TEMPLATE, ...) The printf' function prints the optional arguments under the control of the template string TEMPLATE to the streamstdout'. It returns the number of characters printed, or a negative value if there was an output error.

$ info scanf File: libc.info, Node: Formatted Input Functions, Next: Variable Arguments Input, Prev: Other Input Conversions, Up: Formatted Input

12.14.8 Formatted Input Functions

Here are the descriptions of the functions for performing formatted input. Prototypes for these functions are in the header file `stdio.h'.

-- Function: int scanf (const char *TEMPLATE, ...) The scanf' function reads formatted input from the streamstdin' under the control of the template string TEMPLATE. The optional arguments are pointers to the places which receive the resulting values.

Oh you found it, cool! So it seems that you're using a quite outdated version of coreutils, 8.4 is from 8 years ago, and the current stable version from last year is 8.29. What OS/distribution/version/etc are you using? you think you could upgrade your OS? otherwise some workaround would be needed.

[ling-zhou]

Yes, problem solved by upgrading coreutils to the newest version(8.29), it is not necessary to upgrading OS.

Info Documentation file pages

Vinfo split the Info file in various 'pages' so it's faster to read. You can traverse this pages by following the tags or by using on of the page traversing commands:

                                          :VinfoN :VinfoNext

:VinfoN[ext] Go to the next Info documentation file page. Will fail if the last page is currently loaded.

                                          :VinfoP :VinfoPrevious

:VinfoP[revious] Go to the previous Info documentation file page. Will fail if the last page is currently loaded.

It seems like 'Ctrl-]' does not work for the tags?

It seems like 'Ctrl-]' does not work for the tags?

ah! it happens to me as well, vim's help-tag mechanisms break sometimes, will figure it out.
