kandi X-RAY | bismon Summary

bismon is a C library. bismon has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

bismon (this is a temporary name) is a persistent monitor which (in the future) would interact with the GCC compiler thru plugins. It is (or will become) somehow a successor to my old GCC MELT project; the medium-term goal is also static program source code analysis with the help of GCC. The source code repository (GPLv3+ licensed) is on .. My (Basile Starynkevitch, employed at CEA, LIST in France) work on bismon is partly funded (from start of 2018 to end of 2020) by the European Union, Horizon H2020 programme, CHARIOT project, under Grant Agreement No 780075. Within CHARIOT I will focus on analysis of some kind of IoT software coded in C or C++ and (cross-) compiled by GCC on some Linux desktop. In 2019 - 2021 the development of bismon is also partly funded by the DECODER H2020 project, under Grant Agreement 824231 (related to its Persistent Knowledge Monitor WP1). Currently (start of 2021) bismon still in beta-stage, and it is free software under GPLv3+ license. It is intended for a Linux x86-64 desktop developer's workstation (won't work on Windows or MacOSX or Android). Some still incomplete documentation (as a technical report doc/bismon-doc.pdf in PDF) can be generated (with make then make doc; that command requires you to have a writable $HOME/tmp/ directory). An early (unofficial) draft of that report might be available on

QUESTION

How to use in a canvas a text element with a font described in CSS

Asked 2020-Jan-16 at 00:27

This is within the Bismon project (a GPLv3+ software funded by H2020 European projects), git commit 0e9a8eccc2976f. This draft report describes the software. This question gives more context and motivations. It is about the (hand-written) webroot/jscript/bismon-hwroot.js file, used in some HTML page whose code is generated by Bismon (a specialized web server above libonion).

I added some CSS class for span, e.g. span.bmcl_evalprompt (e.g. in my file first-theme.css).

How do I code the JavaScript to add a text piece in a canvas (preferably using jcanvas with jquery) having the same style (same font, color, etc...) as that span.bmcl_evalprompt ? Do I need to create such a span element in my DOM? Is that even simply possible?

I only care about a recent Firefox (68 at least) on Linux. JQuery is 3.4. I am also using Jquery UI 1.12.1

The idea I had in my mind was to create one single element with coordinates far away from the browser viewport (or X11 window), e.g. at x= -10000 and y= -10000 (in pixels), then add that single badly positioned element into the document DOM, then use traditional Jquery techniques to get the font family, font size, and element size. But is there any better way? Or some Jquery compatible library doing that?

If you simply want to render the text from your span in a canvas, you can access the styling attributes using the function window.getComputedStyle. To make the original span invisible, set its style to display: none.

QUESTION

is g_timeout_add thread-safe (Linux, GTK3, X11)?

Asked 2019-Oct-25 at 11:15

Context: on Linux/Debian/Sid x86-64 for my bismon (GPLv3+) software (described here)
(GTK 3.24, Glib 2.62, Xorg server, function register_gui_postponed_BM, file gui_GTKBM.c)

Question:

Can g_timeout_add be safely called from some other thread than the main thread? I can easily ensure that call would be serialized (using a pthread mutex) but I cannot guarantee it would be called from the main thread. The threads are Pthreads, not Glib threads.

I found both this and that, and they make me think it is indeed safe.... But I might have understood wrongly.

Yes. It boils down to a call to g_source_attach(), which locks the GMainContext it adds the timeout source to.

QUESTION

GTK3 function keys; which are consumed (and unusable from my GTK app)?

Asked 2017-Oct-19 at 11:54

FWIW, the exact program motivating this question is (on Linux/Debian/Sid/x86-64) my bismon on github, commit d43a75fb9f8e13. GTK3 is 3.22.24. If you need to try it, build it with make and run ./bismon. It is in alpha stage, and still not interesting to others than me. It is some kind of DSL interpreter with a GTK interface and a persistent heap.

^{If you want something to appear, click to focus on the middle widget, type the_system there followed by Ctrl Return, but that is not relevant for this question.}

I am successfully able, with commandview_BM (it is the middle widget) being a GtkTextView widget

Trying to decompose your questions so that its easier to answer.

First of all, i would recommend reading The GTK+ Input and Event Handling Model and notice that "GTK+ receives events from the windowing system".

I'm using either Gnome, or XFCE4, or LXDE as my desktop environments. AFAIK I did not configure these specially regarding function keys.

Well, you didn't but "distributions"/window managers do.

As an example, check GNOME Shell Keyboard shortcuts

Most window managers use ALT+Fn keys, being ALT+F4 most known for closing a window. CTRL key is more suitable for user "shortcuts/accelerators".

More importantly, is there a way, from a GTK3 application, to programmatically query which function keys will be reached by some widget (like a GtkTextView) ? I can't think of any...

No, there isn't. Events are emitted/triggered and widgets, if programmed to do so, receive and handle them accordingly, then by checking the event, like you do with your key-press-event handler, you can trigger "actions". Well, theoretically, you could develop a set of setters and getters of handled keys in your own widgets but honestly don't see the point of doing so.

Or else, what is the small set of function keys that I reasonably can expect to use from a Gtk3 application on Linux (with X11, and perhaps later with Wayland)?

I would go for CTRL+Fn, SHIFT+Fn and normal F1 to F12 leaving ALT+Fn reserved for the Windowing system.

Now looking to your concrete example on Github, your handler is already ignoring F11 and F12 due to the condition:

Vulnerabilities

No vulnerabilities reported

Install bismon

Most of bismon is in C99 or C11 (including an increasing amount of generated C code under modules/), but some few hand-written code is in C++14 (notably misc_BM.cc and the BM_makeconst.cc metaprogram generating C headers).

Support

The preferred way to report them is to add some new issue on https://github.com/bstarynk/bismon. Of course, an issue should be self-contained. Please give explicitly the output of bismon --version on your computer if you have been able to build bismon. If the issue is related to building the bismon executable, give explicitly all the Linux commands you have run (after having examined and successfully run the distclean-script.bash script, or just after some fresh git clone command). Mention the output of git log -3. Alternatively (if you don't want to add a github issue), send an email (UTF-8 encoded, HTML5 is preferable) in English, or in French, (or perhaps in Russian, only if you cannot send an email in English or French) to basile.starynkevitch@cea.fr. I will try to answer in English or in French (since my written Russian is so bad). If you need to send a screenshot, attach some image encoded as JPEG or PNG to your email. If you want or need to send several files, archive all of them in a unique directory (whose basename(1) contains only letters, digits, and some underscore _) and make some tar(1) archive of them. Give me explicitly the tar command I need to run (on Linux) to extract your archive. You could assume I have GNU tar version 1.30 or better on my Linux computer. If you send me some C or C++ code to be processed by bismon, allow me explicitly to compile it and add comments (UTF8 encoded) in English, French or Russian. If possible, add some shell script (for GNU bash or for zsh ....) which enables me to reproduce that bug, and name that script in your email or bug report. My employer (if you are outside of CEA ....) could prefer also some information related to funding, formal collaboration, etc... If possible mention them explicitly in English or in French in your email.
