[GRASS-user] grass70 problem with gui

Hi list,

After installin grass70 from "[http://ppa.launchpad.net/grass/grass-devel/ubuntu](http://ppa.launchpad.net/grass/grass-devel/ubuntu)" on Ubuntu 12.04 64, it fails to ``launch grass.
The wxpython gui gives the following error:

You need to install the grass-gui package with

sudo apt-get install grass-gui

A colleague of mine had that same issue last week and that package resolved it

Hi,

2013/12/10 Cesar Augusto Ramírez Franco <caesarivs@gmail.com>:

You need to install the grass-gui package with

sudo apt-get install grass-gui

this is really strange. Isn't this package dependency of `grass`
package? In other word, shouldn't be installed automatically?

I used to compile it from trunk without problem in ArchLinux but since this morning I have the same error message.

g.version -g
version=7.0.svn
date=2013
revision=58433
build_date=2013-12-10

Are there any workaround ?

g.version -r is crashing for me, I just realized it.

right, I just realized it, it's related to r58417. Quickly fixed in
r58436 (back to the native tokenize soubroutine).

I have fully reverted r58417 because with strtok, "A sequence of two
or more contiguous delimiter characters in the parsed string is
considered to be a single delimiter" (man strtok), whereas the
GRASS routine does not merge delimiters.

or more contiguous delimiter characters in the parsed string is
considered to be a single delimiter" (man strtok), whereas the

why? It was useful, for example national DEM/DSM in Czech Republic
(sample data [1]) is provided in the format where coordinates are
separated with *two* or more spaces. In other words, with the native
tokenize function `r.in.xyz sep=space` or `r.in.xyz sep=" "`
(double-space as user could expect that it will work) fails bacouse
G_tokenize("x y", " "); returns {'x', '', 'y'} and not {'x', 'y'}.
With strtok-based tokenizing such string works perfectly.

BTW, `separator` parameter can be string with more than one character,
but native tokenize subroutine fails to tokenize such string with
multiple-character delimiter, eg. G_tokenize("firstSElast", "SE");
returns {'first', '', 'last'} and not {'first', 'last'} as someone
could expect.

OTOH, v.in.ascii format=point expects the same number of tokens in each line:

1|1||name
2|2|3|other_name

must always result in 4 tokens. Here, double pipe works as expected
only if delimiters are not merged.

but native tokenize subroutine fails to tokenize such string with
multiple-character delimiter, eg. G_tokenize("firstSElast", "SE");
returns {'first', '', 'last'} and not {'first', 'last'} as someone
could expect.

Someone else would expect that with "SE" as delimiter argument, the
delimiter can be either "S" or "E".

I would leave G_tokenize() as it is because it is used at too many
different places which expect the current behaviour.

It is not uncommon that ASCII input data need a bit of pre-processing
(tr, sed), e.g. when fields have fixed lengths. Alternatively, add an
option (to respective modules, not to G_tokenize()) to expect fixed
length fields defining the field lengths?

right, we need to have native tokenize() subroutine for such cases. It
was not good idea to replace it directly with tokenize_strtok() even
as a test. Anyway my plan was to introduce a new G_tokenize3() or
G_tokenize_strtok() based on tokenize_strtok(). I believe that such
function would make sense on several places like in `r.in.xyz`.

right, as strtok() behaves.

Agreed.

It is not uncommon that ASCII input data need a bit of pre-processing

right, anyway I think it's still better to handle such issues on
module level. You can hardly ask Windows user to use `tr` or `sed`.
Being user friendly is not so bad idea.

option (to respective modules, not to G_tokenize()) to expect fixed
length fields defining the field lengths?

I still think that G_tokenize_strtok() would make sense to have. Then
`r.in.xyz` or `v.in.ascii` could have special flag which could handle
input files as I described (e.g. columns separated by two spaces).
What do you think?
